Descartes Meditation Essay Example for Free

Descartes Meditation Essay 1. If Descartes’s aim is to find certainty, why does he proceed by doubting as many things as he can? He feels that as long as he goes on believing his old beliefs, laziness and habit will block him from receiving any truths. He feels that if he regards his beliefs in the same way as he does any falsehoods he can remain unbiased when judging information and only then will he receive real truths. 2. What reason does he give for doubting that the senses give knowledge? That a man asleep can have a realistic dream that he is having the same experiences as a man thats awake. 3. What does the experience of â€Å"dreams† show us concerning the senses? He talks about how real dreams appear even though they are proven to be deceiving. And if one can be deceived in a dream by all of their senses can they not also be deceived in reality by some supernatural demon. He says hypothetically that God may not have created earth, shapes, etc. and everything that we sense could be a form of deception. 4. Why can he doubt even that 2=3 = 5. He talks about the fact that he sometimes doubt others who claim to have the most perfect knowledge. And if that can be the case for them cant it also be possible for him to be wrong about â€Å"obvious† truths. Also, if one may feel that if Gods goodness would stop him from being deceived SOME of the time, wouldnt it stop him from being deceived ALL of the time since he is clearly deceived some of the time. Basically he is acknowledging the fact that he could be wrong.

The Role of Women in Screwball Comedy Films :: Movies

The Role of Women in Screwball Comedy Films Joan Wilder: You're leaving? You're leaving me?! Jack Colton: You're gonna be all right, Joan Wilder. Yea. You always were. Like a contemporary Dorothy, Romancing the Stone's Joan Wilder must travel to Columbia and survive incredible adventures to learn that she had always been a capable and valuable person. Romancing the Stone (Robert Zemeckis, 1984) is part of a series of 1980s action comedies that disrupted previous expectations for female heroines. These female protagonists manage to subvert the standard action narrative and filmic gaze, learning to rescue themselves and to resist others' limited vision of them. Not only did these action comedies present strong female characters, they also offered a new filmic experience for female audiences. The commercial success of comic action heroines paved the way for women to appear in serious action roles--without the personal sacrifices required of Sigourney Weaver’s Ripley. Figures like Joan Wilder serve as an important link between previous strong yet feminine screen personas and current female stars. Led by Laura Mulvey, feminist film critics have discussed the difficulty presented to female spectators by the controlling male gaze and narrative generally found in mainstream film, creating for female spectators a position that forces them into limited choices: "bisexual" identification with active male characters; identification with the passive, often victimized, female characters; or on occasion, identification with a "masculinized" active female character, who is generally punished for her unhealthy behavior. Before discussing recent improvements, it is important to note that a group of Classic Hollywood films regularly offered female spectators positive, female characters who were active in controlling narrative, gazing and desiring: the screwball comedy. Comedy often allows for a subversion of the status quo that is not tolerated in more serious genres. Beginning in the 1930s, the subgenre of screwball comedy presented female characters who were active and desiring, without evoking negative characterizations as "unfeminine" or "trampish." Screwball comedies represent a specific form of romantic comedy that features a complicated situation--or more often a series of complications--centered around a strong-willed, unpredictable female. The comedy is generally physical as well as verbal. Screwball and other forms of romantic comedy do not just reverse the masculine/active, feminine/passive paradigm--which as E. Ann Kaplan notes accomplishes little in terms of change--but instead strengthens the female and weakens the male just enough to put them on more equal footing.

Khan Academy

With the Khan-Academy systematics, I feel that it is actually a tool that helps many others like myself who may be attending math classes in school. As a child in elementary school, the Internet program helped me start filling the â€Å"Swiss cheese† gaps Khan talked about. The â€Å"Swiss cheese† gaps, are the things people didn’t learn while they were in math classes, where the teacher simply did not go into great detail of explaining. The way the gaps began to be filled, was that it actually challenged me to a greater potential that I thought could not be achieved.In fact many others in my class treated the program as a game in a good way, as on the Internet program one wins a copious amount of prizes in which we used to brag to each other on. To win prizes they may consist of answering a specific amount of questions or becoming persistent at working with Khan-Academy. Something the program has definitely made up is the intolerable position in which unfit teac hers put there students into. The math teachers usually do not help enough or teach only one way, and this is the full reason on why some student actually end up failing their classes.With Khan-Academy some how the student that ended up failing their math classes, now have grades like the visually impaired gifted ones, which also may show how poorly the teachers may have taught their students. Another good point Khan made happen to be the interactions that started to make place amongst the student of classes, in which the ones that did not understand the lessons could know get taught by other students that may have had a full understanding of whatever the problem or problems were.A way the Khan-Academy is assuring that the help that is given is accurate, is that within the program itself it has a way a keeping track who is excelling, and who may not be. Either way one may take the program, it benefits everyone in a various amount of ways and has been a major help in classes across A merica by helping student who did not excel in math class before.

Stages and Prognosis of Breast Cancer - 3785 Words

Breast Cancer 3 Running Head: Stages and Prognosis of Breast Cancer Stages and Prognosis of Breast Cancer Abstract Breast cancer is one of the major causes of death in cancer patients all over the world. Tumor node- metastasis (TNM) is a standard staging system for breast cancer. TNM staging system also provides the basis for the prognosis for breast cancer. The prognosis for breast cancer is majorly based on two factors; tumor size and biological factors. However, these factors have been further divided into subdivisions and have been discussed. In this paper the stages of breast cancer have been discussed along with the prognosis of breast cancer in detail. Stages and Prognosis of Breast Cancer Introduction It has been found that nearly 1.3 million women are suffering from breast cancer all over the world. There are different stages of breast cancer starting from 0 to IV. Cancer staging systems are intended to provide information on prognosis and to guide clinicians in treatment planning (Greene, 2002)(1). Traditionally, breast cancer has been staged using the American Joint Committee on Cancer (AJCC) and is known as the Tumor node- metastasis (TNM) system. Developed in 1959, this system has been periodically updated to reflect new knowledge regarding the relationship between disease extent and prognosis, ensuring that the system maintains clinical relevance (Edge, 2009)(2).

The methods and hardware for recording new stock items, including their location in a large warehouse. 1. RFID for recording new stock items RFID is the technology that uses radio waves to automatically identify items. An RFID system consists of an antenna and a transceiver, which read the radio frequency and transfers the information to a processing device (reader) and a transponder, or RF tag, which contains the RF circuitry and information to be transmitted. The antenna provides the means for the integrated circuit to transmit its information to the reader that converts the radio waves reflected back from the RFID tag into digital information that can then be passed on to computers that can analyze the data. RFID are used for recording new stock items and their location for stock in of receipt of ordered items. 2. Barcodes for recording new stock items Barcode has a various way for encoding numbers and letters by using a combination of bars and spaces of varying widths. Think of barcodes as another way of writing since barcodes replace keying data. In business, the correct use of BARCODES can reduce inefficiencies and increase companys productivities. Barcodes are easy, fast and an exact way of entering data. A barcode doesnt include descriptive data. Typically barcode has ID data encoded in it, and data is used by a computer to look up all detail information associated with the data. 3. WIRELESS PORTABLE BARCODE SCANNERS for recording new stock items A wireless solution is the perfect one when you need to collect information at a far location, and need the information instantly. A wireless portable barcode scanner is built into a terminal, and uploads data to the host as its scanned, exactly and instantly. Wireless portable barcode products can allow the user scan the information at the point-of-activity, which makes it ideal for industry. 4. The methods for recording new stock items The methods for recording new stock items involve deducting each order, new stock item received, and maintain a cumulative balance. Stock record card method is the most basic style of stock record and it can be hand-written or keyed where the stock is located and the maximum and minimum quantities to be held in stock. C. The methods and hardware for processing order. Order processing starts with the receipt of an order from a customer. It may be obtained by a salesperson, be telephoned in, or arrive by mail. Regular buyers and sellers are often linked electronically. As the buyers inventories become low, an electronic purchase order is generated. It is communicated to the seller, whose computers will determine that the goods are available, and the seller. 1.

Every business needs how to determine the stock levels. There are 3 level of stock average. They are maximum stock level, minimum stock level and reorder level. Maximum Stock Level the maximum ever held in storage. The stock total will not usually be this high. Maximum Stock Level = Amount used each month x Months between orders x 3 Minimum Stock level When the stock level of an item falls below the minimum quantity, it is time to reorder the product. There are some instances where it is difficult to maintain accurate stock levels because it is impractical to record each individual material disbursement. Stock in hand + Stock received Stock used = Balance left Re-order Stock Level this figure gives a quick reference to see when you need to re-order. When the stock reaches this level, or below, you will need to re-order supplies on the next ordering date. Re-order Level = (amount used each month) x (Months between orders) x 2 The reorder level is the sum of the safety stock and the forecast requirement within the replenishment lead time or the overall lead time for articles produced in-house. Re-order level approach Average stock levels stay more or less the same and are less responsive to changes in demand. There is a risk of stock outs with inexpected rising demand but outstanding re-supply orders can be chased. E. Other hardware for the complete system. Printer Epson C-58 Colour Printer. Handheld computer Modern or FTP link 80 GB HDD(7200 rpm) UPS 600 VA (Power tree) Classic 2 GB DDR3 Memory Recommendation For amazing book store, used RFID and barcodes as a hardware for recording new stock items.

Using barcodes as a hardware for processing order is convenience and for use to scan in the order number from the packing slip. Use Receipt Printer is suitable because it can support direct serial connection or any printer that connects via USB, parallel or Ethernet and is supported by a compatible OPOS driver. Network Topologies There are four basic types of Network Topology. They are Star Topology Ring Topology Bus Topology Mesh topology Definition of star topology Star topology also call star network. It is the most common of used of network topologies. In star Topology there is a central connection point called the hub which is a computer hub or sometimes just a switch where computers and devices are connect to a central hub. This is topology has only one central server node. All nodes are connected to a central node. Central device received or sent data. In the star topology, data transmitting between nodes is pass to the central node which transmit again the data to other nodes. Advantages of star topology If there is a failure in cable, only one computer will affect and it will not affect the entire network. It is simple in function so it is easy to mange. It is easy to troubleshoot because the problems can be easily located in this network. It is easy to install. It is easy to find the defects and to remove the parts. Transmitting data to unnecessary nodes can control. Disadvantages of star topology All the computers connected to a central hub would be disconnected when the central hub fails. All the operations of computers are depending upon the operation of the central server. The network may be slow if there are many nodes. It require more length of cable than a linear topology. Ring Topology Ring topology also known as ring network. Data travels from node to node. Packet of data is passed only in one direction, receive data node to node. This topology has only one pathway between any two nodes, ring networks may be disrupted by the failure of a single link. A token, or small data packet, is continuously passed around the network. When a device needs to transmit, it reserves the token for the next trip around, then attaches its data packet to it. The receiving device sends back the packet with an acknowledgment of receipt, then the sending device puts the token back out on the network. Data are passed in one direction only, being received by each node and then transferred to the next node. Advantages of ring topology Network server is not managing the connectivity between the computers. Ring networks are moderately easy to install. Using token ring can create much larger network Disadvantages of ring topology A single break in the cable can disrupt the entire network. The failure of a single node of the network can cause the entire network to fail. The movement or changes made to network nodes affects the performance of the entire network. Linear bus topology The topology consists of main cable with a terminator at each end. Nodes are connected to the linear cable. A bus network uses a multi-drop transmission medium, all node on the network share a common bus and thus share communication. This allows only one device to transmit at a time. Data frames include source and destination addresses, where each station monitors the bus and copies frames addressed to itself.Computer connect this network will check these address and then receive and accept the data.If data sends in parallel, network use Carrier Sense Multiple Access with Collision Detection (CSMA/CD) access method for prevent data collision. Advantages of linear bus topology The computers are easy to connect. If one of the station fails, the other are not affect. Not need very much length of cable than a star topology. The complexity of wire is low. Disadvantages of linear bus topology If the main cable is a break, the whole network is shut down And so, this can become problem. Terminators are need. Definition of mesh topology In a mesh topology, the nodes are connected directly all other nodes. Each node can transmit, receive and routing data. This topology connects devices with multiple paths so redundancies exist. This topology is used mostly for wireless network. There are two types of mesh topology. They are fully mesh and partial mesh. Advantage It is reliable. No gateway computer so nodes can create their own paths. Disadvantage This topology can cause redundancy of many of the network connections. Need very much cable than the LAN topologies. Network Media There are four basic types of network cables. They are Fiber Optic cable Coaxial cable Unshielded Twisted pair cable (UTP) Shielded twisted pair Cable (STP) Fiber Optic Cable Fiber Optic Cable is a technology uses glass (or plastic) threads (fibers) to transmit data. It consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves. The advantages of fiber optic cable are it has high greater bandwidth so they can be used over greater distance than copper cable. Fiber optic cables are thinner and lighter than metal cable so it reduce size and weight and that it keep environmental protection and overall system economy. The disadvantage of fiber optic cable is that the cable is expensive to install. In addition, they are more fragile than wire and are difficult to splice. Coaxial Cable The coaxial cable is transmission line for high-frequency signals and carries both video and audio singals. The coaxial cable is used by Satellite Company. It also used by cable TV between the community antenna and user homes and business. There are two types of coaxial cables. They are thin coaxial and thick coaxial. Advantages of Coaxial Cable It is highly resistant to signal interference it can support greater cable lengths between network devices than twisted pair cable. Disadvantages of Coaxial Cable Great noise. High installation cost. More expensive than twisted pair cable. It is difficult to install. Unshielded Twisted pair cable Unshielded twisted pair cable is composed of pair of wires. Unshielded twisted pair cable (UTP) is used in a variety of networks. UTP computer networking and used to connect devices in a Local area network. it may react to radio or electrical interference. Advantages of unshielded twisted pair cable It is easy to install. It is low cost of materials. It is less expensive than other types of networking media. It costs less per foot than any other type of LAN cabling. Disadvantages of unshielded twisted pair cable No additional shielding to protect the medium from noise. It may react to radio or electrical interference. Recommendation I choose Fiber Optic Cable and star topology for build stock control system in Amazing book store. I think star topology is most suitable for the amazing book company because it is easy to mange and simple in function. It also has good performance. Failing one cable can affect only one computer and not affect the whole of network. If one of the computer fail does not effect other devices and computers in the network. I choose UTP cable for the amazing book company. It is easy to install, low cost of materials. By using this cable, it can get many benefits. Other cable are not suitable for this site because fiber optic cable is easy fragile and difficult to splice. Coaxial cable is difficult to install, great noise and have high installation cost. So, it is the best using the UTP cable. Keep database and connect to the workstation of website for the updating or recording information of book. When the customer buy or look detail information, the serve check the company database and display the information to the customer such as prices, discount, available quantity. In any business, delivery system is important for product. Different business use different delivery methods. I investigate the electronic systems that could be used for recording the transfer of packages from Amazing books to the courier depot, then to the courier vehicle, and finally to the customer. The amazing book company uses the courier for delivery the package to the customer. Firstly, the amazing book company registers in the courier website. The courier company give the invoice ID and password to enter and look the delivery information of package in the website. The amazing book company gives the invoice ID and password to the customer can enter and look the package information. The courier company made delivery product by ship or car or air. The courier company website describes air delivery time information, ship delivery time information and car delivery time information in the website. The website also describe the delivery time information, overseas delivers informatio n, price information depend upon the location. The packages are carried by ship1-8days. So, the customer needs to know that information. So, the website admin need to repair and update the delivery information. And also need to send e-mail that describes the delivery information. The website also describes the package arrive location information for the customer. So, the customer can know their package arrive location. If the late condition of package such as when the ship meet the storm and so the delivery package can late. The customer can worry that their product are not arrive at right time. So, the website needs to give that information to the customer and amazing book company. The customer can change the delivery information option using the invoice ID and password but the delivery option can not change after the order has been confirmed. If goods are damaged due to courier or something, the website describe damage package and the website admin send mail. The customer can pay website by credit card when the delivery is complete. The website also describes insurance of package. Website admin always update website information. Website admin also describes the site map of website and help system. AIDC (Automatic Identification and Data Capture) is also requires in delivery system and it is automatically methods of identifying objects, collecting data about them, and entering that data directly into bar code. As software Rifidi is require for RFID(Radio frequency identification, it is to provide a development tool that greatly simplifies the way RFID application are developed. That software also defined RFID Tags and RFID Readers. Recommendation I think RFID (Radio frequency identification) is necessary for the delivery system because it is need to identify the product and quick for delivery process. And also use RFID software of Rifidi. Use OCR(Optical Character recognition) and OMR(Optical Mark Recognition) in delivery system. OCR use for printed text recognition and OMR use for marks recognition. Not only small business but also large business needs one important duty. That duty is to prevent theft. So, you need to know the method of how to prevent theft and monitoring staff and when theft occurs how you adjust stock levels. Choosing good character staff To prevent theft for stock control system, we will choose good character employee because the employee can thieve the stock easily in the company. So, choosing good character employee is important in any business. When hiring a new employee, you must take job application that have a section inquiring about criminal history. We will also need strictly control of staff. We also restrict the position of staff for entering of stock room. We should train the staff in dealing with thieves and set up a clear policy. We must set up rules for stock room such as when the staff out the stock room make checking the staff body, the staff that enters the stock room must sign in the stock entering file and restrict taking other things to the stock room. We set up the electronic thing that monitor staff. Keeping security guard men for stock room We should keep two types of security guard men for stock room, the first type of security guard men for looking stock room at day duty and the other type of security guard men for at night. Using fingerprint for prevention theft To prevent theft we should use stock security method, hardware, software and network. As hardware, we should use fingerprint in entering stock room. Using CCTV for prevention theft To prevent theft we should use stock security method, hardware, software and network. As hardware, we should use CCTV in stock room and check every 24 hours. Keeping the user name and password for prevention of theft To prevent theft we should keep user name and password in stock room. We should change the password one time in a month for security. We give the password and user name only to the authorized person. If there are unsuccessful 3 times attempt log in, we should close workstation. And after about 30 minutes, we should allow to type the user name and password again. Otherwise, we keep the security alarm system that connects to the user name and password system and the security alarm that ring when there are many times unsuccessful attempt log in. Other method for prevention theft We should always check report that include product in and out of stock and always check stock level. We should allow only authorized person to enter stock. When the stocks arrive, we should check the product list in delivery note and we should use RFID (Radio Frequency Identification) for check product quantity. We should keep delivery bay secure. We need good record for stock secure. We should also keep track of when stock is sold, used, replaced or thrown away. We need also monitoring the staff to prevent theft. We should use many tool and install security cameras and surveillance mirrors for monitoring the staff and recording staff activitiesbyCCTV cameras. Adjusting stock level when theft occurs The thieving of stock can be staff in our business or thieve from the outside. However, when the theft occurs in our business we need adjusting stock level and resolving the problem. If the customer orders are stolen, we give information that your orders are stolen and wait the customer and make the order for customer again. If our stock are stolen, we check the supplier delivery product quantity and the product that arrive in our stock quantity. If supplier wrong delivery the product, we give information to the supplier that you delivery the wrong product quantity. We should record that how many products are stolen. Recommendation Use the software, hardware and network requirement to reduce the threat of stock theft. I keep the fingerprint in entrance of stock room. Use username and password to enter the stock room. Keep CCTV for monitoring the staff and recording the staff activities. Use the stock security software for control stock room with computer. If the theft occurs in my stock, I give information that your orders are stolen and wait the customer. And then, make the order for customer again. We should fill the product units that are stolen in our stock.

Order information It should have quantity of book u order, total cost, Delete button for remove the item in your shopping basket, Delivery Company and delivery time for order. Other information It should describe Member information, Member price, and discount for much order and promotion period. B. The methods and hardware for recording new stock items, including their location in a large warehouse. 1. RFID for recording new stock items RFID is the technology that uses radio waves to automatically identify items. An RFID system consists of an antenna and a transceiver, which read the radio frequency and transfers the information to a processing device (reader) and a transponder, or RF tag, which contains the RF circuitry and information to be transmitted. The antenna provides the means for the integrated circuit to transmit its information to the reader that converts the radio waves reflected back from the RFID tag into digital information that can then be passed on to computers that can analyze the data. RFID are used for recording new stock items and their location for stock in of receipt of ordered items. 2. Barcodes for recording new stock items Barcode has a various way for encoding numbers and letters by using a combination of bars and spaces of varying widths. Think of barcodes as another way of writing since barcodes replace keying data. In business, the correct use of BARCODES can reduce inefficiencies and increase companys productivities. Barcodes are easy, fast and an exact way of entering data. A barcode doesnt include descriptive data. Typically barcode has ID data encoded in it, and data is used by a computer to look up all detail information associated with the data. 3. WIRELESS PORTABLE BARCODE SCANNERS for recording new stock items A wireless solution is the perfect one when you need to collect information at a far location, and need the information instantly. A wireless portable barcode scanner is built into a terminal, and uploads data to the host as its scanned, exactly and instantly. Wireless portable barcode products can allow the user scan the information at the point-of-activity, which makes it ideal for industry. 4. The methods for recording new stock items The methods for recording new stock items involve deducting each order, new stock item received, and maintain a cumulative balance. Stock record card method is the most basic style of stock record and it can be hand-written or keyed where the stock is located and the maximum and minimum quantities to be held in stock. B. The methods and hardware for processing order. Order processing starts with the receipt of an order from a customer. It may be obtained by a salesperson, be telephoned in, or arrive by mail. Regular buyers and sellers are often linked electronically. As the buyers inventories become low, an electronic purchase order is generated. It is communicated to the seller, whose computers will determine that the goods are available, and the seller. 1. Phone Order Sometimes customer wants to hear a friendly and sometime online connection is not good for made order for the customer and so, the customer made order by phone. Phone orders are made customer satisfy because the customer can tell the point of that they want. 2. Online order Nowadays, the most people use the internet and if they want to buy something, they made order from online. Ordering online is easy, fast, and safe because online orders are usually used credit cards payment. Customers can purchase product by sending an order to a business which will consists details information of which products they want to purchase and how many. Order can be received Pass the post on order forms. This will need to be entered as records on the orders file onto the computer. Online. Customer can send order by using email or over the Internet. This order would be saved in the orders file. The order file would contain fields with information about item details and quantities the date of the order money owing or received from the customer. customer detail In online order process, it will need Credit Card Processing Verification Tool. It is check any credit card number to ensure its legitimacy. It can download free and using this tool to instantly eliminate fraudulent orders and invalid card numbers. Barcode for processing order When the barcode is scanned, information is sent to the computer and placed in the desired application. Its used to scan in the order number from the packing slip and its used to scan the serial numbers of the products being shipped, which also helps when tracking inventory. If the order has items that have serial numbers, click on the Add Serial # link, and scan the serial number barcodes from the products for that order. C. The methods and hardware for recording items dispatched. An invoice is sent requesting the amount of money due for the order when the goods are dispatched. The customer may give by cheque. If you pay for your item using PayPal, or the seller marks the item on their eBay page as Payment Received, the payment status in eBay will be updated automatically to show as Payment Sent. Although, if you paid using another payment method and you manually marks the item as Payment Sent, the seller is not notice automatically. Receipt Printer Any serial printer that supports direct serial (RS232) connection or any printer that connects parallel, via USB or Ethernet and is supported by a compatible OPOS driver. Both current Samsung OPOS and Epson drivers have been tested and are compatible with EPOS-Excel. HP Printer Duplex for LaserJet 8000 8100 8150 This HP printer duplex assembly allows automatic printing on both sides of the paper and handles booklet printing. Epson LX-300+II Dot Matrix Printer Designed for demanding work environments, the Epson LX-300+II offer the speed, reliability and user-friendly features you need for critical business requirements and get powerful performance, plus easy system integration with Parallel and Serial ports, as well as fast USB connectivity.

Built to handle all your critical tasks, the Epson LX-300 +II features multiple paper paths for greater versatility. It also includes eight built-in bar codes so you can customize documents as needed. D. The process for determining and flagging up stock reorder levels. Every business needs how to determine the stock levels. There are 3 level of stock average. They are maximum stock level, minimum stock level and reorder level. Maximum Stock Level the maximum ever held in storage. The stock total will not usually be this high. Maximum Stock Level = Amount used each month x Months between orders x 3 Minimum Stock level When the stock level of an item falls below the minimum quantity, it is time to reorder the product. There are some instances where it is difficult to maintain accurate stock levels because it is impractical to record each individual material disbursement. Stock in hand + Stock received Stock used = Balance left Re-order Stock Level this figure gives a quick reference to see when you need to re-order. When the stock reaches this level, or below, you will need to re-order supplies on the next ordering date. Re-order Level = (amount used each month) x (Months between orders) x 2 The reorder level is the sum of the safety stock and the forecast requirement within the replenishment lead time or the overall lead time for articles produced in-house. Re-order level approach Average stock levels stay more or less the same and are less responsive to changes in demand. There is a risk of stock outs with inexpected rising demand but outstanding re-supply orders can be chased. Other hardware for the complete system. Printer Epson C-58 Colour Printer. Handheld computer Modern or FTP link 80 GB HDD(7200 rpm) UPS 600 VA (Power tree) Classic 2 GB DDR3 Memory Recommendation For amazing book store, used RFID and barcodes as a hardware for recording new stock items. RFID are used for recording new stock items and their location for stock in of receipt of ordered items. Barcodes are used for recording new stock items and their location for stock in of receipt of ordered items. Using barcodes as a hardware for processing order is convenience and for use to scan in the order number from the packing slip. Use Receipt Printer is suitable because it can support direct serial connection or any printer that connects via USB, parallel or Ethernet and is supported by a compatible OPOS driver. Review for Task 2- I use the internet for search the information of computerized stock control system. I investigate 4 computerized stock control systems for the task 2. I write the recommendation for the computerized stock system. By making task 2, I increase the knowledge about what hardware and methods are more convenience for the stock control system to record new stock items, what hardware are more reliable for order processing and much know what hardware for recording items dispatched. Task 3 Network Topologies There are four basic types of Network Topology. They are Star Topology Ring Topology Bus Topology Mesh topology Definition of star topology Star topology also call star network. It is the most common of used of network topologies. In star Topology there is a central connection point called the hub which is a computer hub or sometimes just a switch where computers and devices are connect to a central hub. This is topology has only one central server node. All nodes are connected to a central node. Central device received or sent data. In the star topology, data transmitting between nodes is pass to the central node which transmit again the data to other nodes. Advantages of star topology If there is a failure in cable, only one computer will affect and it will not affect the entire network. It is simple in function so it is easy to mange. It is easy to troubleshoot because the problems can be easily located in this network. It is easy to install. It is easy to find the defects and to remove the parts. Transmitting data to unnecessary nodes can control. Disadvantages of star topology All the computers connected to a central hub would be disconnected when the central hub fails. All the operations of computers are depending upon the operation of the central server. The network may be slow if there are many nodes. It require more length of cable than a linear topology. Ring Topology Ring topology also known as ring network. Data travels from node to node. Packet of data is passed only in one direction, receive data node to node. This topology has only one pathway between any two nodes, ring networks may be disrupted by the failure of a single link. A token, or small data packet, is continuously passed around the network. When a device needs to transmit, it reserves the token for the next trip around, then attaches its data packet to it. The receiving device sends back the packet with an acknowledgment of receipt, then the sending device puts the token back out on the network. Data are passed in one direction only, being received by each node and then transferred to the next node. Advantages of ring topology Network server is not managing the connectivity between the computers. Ring networks are moderately easy to install. Using token ring can create much larger network Disadvantages of ring topology A single break in the cable can disrupt the entire network. The failure of a single node of the network can cause the entire network to fail. The movement or changes made to network nodes affects the performance of the entire network. Linear bus topology The topology consists of main cable with a terminator at each end. Nodes are connected to the linear cable. A bus network uses a multi-drop transmission medium, all node on the network share a common bus and thus share communication. This allows only one device to transmit at a time. Data frames include source and destination addresses, where each station monitors the bus and copies frames addressed to itself.Computer connect this network will check these address and then receive and accept the data.If data sends in parallel, network use Carrier Sense Multiple Access with Collision Detection (CSMA/CD) access method for prevent data collision. Advantages of linear bus topology The computers are easy to connect. If one of the station fails, the other are not affect. Not need very much length of cable than a star topology. The complexity of wire is low. Disadvantages of linear bus topology If the main cable is a break, the whole network is shut down And so, this can become problem. Terminators are need. Definition of mesh topology In a mesh topology, the nodes are connected directly all other nodes. Each node can transmit, receive and routing data. This topology connects devices with multiple paths so redundancies exist. This topology is used mostly for wireless network. There are two types of mesh topology. They are fully mesh and partial mesh. Advantage It is reliable. No gateway computer so nodes can create their own paths. Disadvantage This topology can cause redundancy of many of the network connections. Need very much cable than the LAN topologies. Network Media There are four basic types of network cables. They are Fiber Optic cable Coaxial cable Unshielded Twisted pair cable (UTP) Shielded twisted pair Cable (STP) Fiber Optic Cable Fiber Optic Cable is a technology uses glass (or plastic) threads (fibers) to transmit data. It consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves. The advantages of fiber optic cable are it has high greater bandwidth so they can be used over greater distance than copper cable. Fiber optic cables are thinner and lighter than metal cable so it reduce size and weight and that it keep environmental protection and overall system economy. The disadvantage of fiber optic cable is that the cable is expensive to install. In addition, they are more fragile than wire and are difficult to splice. Coaxial Cable The coaxial cable is transmission line for high-frequency signals and carries both video and audio singals. The coaxial cable is used by Satellite Company. It also used by cable TV between the community antenna and user homes and business. There are two types of coaxial cables. They are thin coaxial and thick coaxial. Advantages of Coaxial Cable It is highly resistant to signal interference it can support greater cable lengths between network devices than twisted pair cable. Disadvantages of Coaxial Cable Great noise. High installation cost. More expensive than twisted pair cable. It is difficult to install. Unshielded Twisted pair cable Unshielded twisted pair cable is composed of pair of wires. Unshielded twisted pair cable (UTP) is used in a variety of networks. UTP computer networking and used to connect devices in a Local area network. it may react to radio or electrical interference. Advantages of unshielded twisted pair cable It is easy to install. It is low cost of materials. It is less expensive than other types of networking media. It costs less per foot than any other type of LAN cabling. Disadvantages of unshielded twisted pair cable No additional shielding to protect the medium from noise. It may react to radio or electrical interference. Recommendation I choose Fiber Optic Cable and star topology for build stock control system in Amazing book store. I think star topology is most suitable for the amazing book company because it is easy to mange and simple in function. It also has good performance. Failing one cable can affect only one computer and not affect the whole of network. If one of the computer fail does not effect other devices and computers in the network. I choose UTP cable for the amazing book company. It is easy to install, low cost of materials. By using this cable, it can get many benefits. Other cable are not suitable for this site because fiber optic cable is easy fragile and difficult to splice. Coaxial cable is difficult to install, great noise and have high installation cost. So, it is the best using the UTP cable. Keep database and connect to the workstation of website for the updating or recording information of book. When the customer buy or look detail information, the serve check the company database and display the information to the customer such as prices, discount, available quantity. Review for Task 3- I search the information from the internet and reference information for the task 3. I know about the network topology and network cable than before I am not making the task 3. Task 4 In any business, delivery system is important for product. Different business use different delivery methods. I investigate the electronic systems that could be used for recording the transfer of packages from Amazing books to the courier depot, then to the courier vehicle, and finally to the customer. The amazing book company uses the courier for delivery the package to the customer. Firstly, the amazing book company registers in the courier website. The courier company give the invoice ID and password to enter and look the delivery information of package in the website. The amazing book company gives the invoice ID and password to the customer can enter and look the package information. The courier company made delivery product by ship or car or air. The courier company website describes air delivery time information, ship delivery time information and car delivery time information in the website. The website also describe the delivery time information, overseas delivers informatio n, price information depend upon the location. The packages are carried by ship1-8days. So, the customer needs to know that information. So, the website admin need to repair and update the delivery information. And also need to send e-mail that describes the delivery information. The website also describes the package arrive location information for the customer. So, the customer can know their package arrive location. If the late condition of package such as when the ship meet the storm and so the delivery package can late. The customer can worry that their product are not arrive at right time. So, the website needs to give that information to the customer and amazing book company. The customer can change the delivery information option using the invoice ID and password but the delivery option can not change after the order has been confirmed. If goods are damaged due to courier or something, the website describe damage package and the website admin send mail. The customer can pay website by credit card when the delivery is complete. The website also describes insurance of package. Website admin always update website information. Website admin also describes the site map of website and help system. AIDC (Automatic Identification and Data Capture) is also requires in delivery system and it is automatically methods of identifying objects, collecting data about them, and entering that data directly into bar code. As software Rifidi is require for RFID(Radio frequency identification, it is to provide a development tool that greatly simplifies the way RFID application are developed. That software also defined RFID Tags and RFID Readers. Recommendation I think RFID (Radio frequency identification) is necessary for the delivery system because it is need to identify the product and quick for delivery process. And also use RFID software of Rifidi. Use OCR(Optical Character recognition) and OMR(Optical Mark Recognition) in delivery system. OCR use for printed text recognition and OMR use for marks recognition. Review for Task 4- I investigate the electronic system from the internet and get information. Then I do task 4 and look the information that search from the internet as a reference and write recommendation. I get more knowledge concerning delivery system by finishing task 4. Task 5 Not only small business but also large business needs one important duty. That duty is to prevent theft. So, you need to know the method of how to prevent theft and monitoring staff and when theft occurs how you adjust stock levels. Choosing good character staff To prevent theft for stock control system, we will choose good character employee because the employee can thieve the stock easily in the company. So, choosing good character employee is important in any business. When hiring a new employee, you must take job application that have a section inquiring about criminal history. We will also need strictly control of staff. We also restrict the position of staff for entering of stock room. We should train the staff in dealing with thieves and set up a clear policy. We must set up rules for stock room such as when the staff out the stock room make checking the staff body, the staff that enters the stock room must sign in the stock entering file and restrict taking other things to the stock room. We set up the electronic thing that monitor staff. Keeping security guard men for stock room We should keep two types of security guard men for stock room, the first type of security guard men for looking stock room at day duty and the other type of security guard men for at night. Using fingerprint for prevention theft To prevent theft we should use stock security method, hardware, software and network. As hardware, we should use fingerprint in entering stock room. Using CCTV for prevention theft To prevent theft we should use stock security method, hardware, software and network. As hardware, we should use CCTV in stock room and check every 24 hours. Keeping the user name and password for prevention of theft To prevent theft we should keep user name and password in stock room. We should change the password one time in a month for security. We give the password and user name only to the authorized person. If there are unsuccessful 3 times attempt log in, we should close workstation. And after about 30 minutes, we should allow to type the user name and password again. Otherwise, we keep the security alarm system that connects to the user name and password system and the security alarm that ring when there are many times unsuccessful attempt log in. Other method for prevention theft We should always check report that include product in and out of stock and always check stock level. We should allow only authorized person to enter stock. When the stocks arrive, we should check the product list in delivery note and we should use RFID (Radio Frequency Identification) for check product quantity. We should keep delivery bay secure. We need good record for stock secure. We should also keep track of when stock is sold, used, replaced or thrown away. We need also monitoring the staff to prevent theft. We should use many tool and install security cameras and surveillance mirrors for monitoring the staff and recording staff activitiesbyCCTV cameras. Adjusting stock level when theft occurs The thieving of stock can be staff in our business or thieve from the outside. However, when the theft occurs in our business we need adjusting stock level and resolving the problem. If the customer orders are stolen, we give information that your orders are stolen and wait the customer and make the order for customer again. If our stock are stolen, we check the supplier delivery product quantity and the product that arrive in our stock quantity. If supplier wrong delivery the product, we give information to the supplier that you delivery the wrong product quantity. We should record that how many products are stolen. Recommendation Use the software, hardware and network requirement to reduce the threat of stock theft. I keep the fingerprint in entrance of stock room. Use username and password to enter the stock room. Keep CCTV for monitoring the staff and recording the staff activities. Use the stock security software for control stock room with computer. If the theft occurs in my stock, I give information that your orders are stolen and wait the customer. And then, make the order for customer again. We should fill the product units that are stolen in our stock. Review for Task 5- In task 5, I write about the prevention of theft and monitoring the staff and when the theft occurs how adjust stock level. This task give many knowledge about how protect the stock, how monitor the staff and when theft occurs how adjust stock level. So, I know more about if the stock theft occurs how I will do.

The Effect of Temperature free essay sample

An enzyme is a type of protein that, through its own structure including hydrogen bonds, acts like a biological catalyst and is able to accelerate the biochemical reaction rate by lowering the activation energy of the whole process, without which cells could hardly practice any physiological functions within human bodies (Sizer, 1943). Found in the saliva and pancreatic secretions of animals including human beings as well as the plant seeds, bacteria and fungi (Siddiqui et al. We will write a custom essay sample on The Effect of Temperature or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page , 2010), the enzyme ? -amylase that was studied during the experiment has significant impact on the hydrolysis of starch. By breaking the alpha, 1-4 glycosidic linkages in the carbohydrates, amylase hydrolyzes the starch, a polysaccharides that is stored in plants and cannot be directly digested by animal cells, into maltose, a disaccharide that later generate two units of glucose to undergo metabolisms and provides necessary energy (Slaughter et al. , 2001). The enzymatic activity of ? amylase is facilitated by calcium and chloride ions during the hydrolysis (Marini, 2006 and Siddiqui et al. , 2010). The complete digestion of starch and formation of maltose and glucose can be examined through the iodine test when I2KI reagent is added into the solution and remains brown instead of turning into dark blue, marking that all the molecules of starch have been fully hydrolyzed (Hanes, 1932). While amylase effectively activates the hydrolysis of starch, the efficiency of the catalytic process is influenced by several factors including temperature, pH level and the concentration of the substrates etc. In this experiment, as the ? -amylase is a type of protein, the efficiency of enzyme is highly related to its hydrogen bonds which are affected by the temperature. Though the enzyme is collected from the porcine pancreas, due to its structural similarities to amylase in human bodies, the behaviors of two amylases should resemble each other. Given that under extreme temperature enzymes will be denatured and unable to function and the constant temperature of pigs is around 39Â °C, the hypothesis of this experiment is that at 37Â °C amylase will catalyze the hydrolysis with the highest speed, followed by amylase at 22Â °C. Amylase at 0Â °C will react extremely slowly due to the crystallization of hydrogen bonds and at100Â °C, amylase will lose its function since it will be denatured. Materials and Methods Four test tubes were marked from A1 to A4. Then, 2mL of 1% starch solution from Carolina Biological Supply Company, 4mL of deionized water and 1mL of 6. 8 hydrion buffer from VWR International/ Micro Essential Laboratories were added into each tube. Another four test tubes were also labeled from B1 to B4 and added 1mL of 1% ? -amylase from porcine pancreas from Sigma Aldrich. Eight tubes were paired according to the same number (A1and B1 etc. and assigned to environments at different temperature: Tube A1 and B1 were placed into a water bath at 100Â °C; Tube A2 and B2 were placed into a water bath at 37Â °C; Tube A3 and B3were placed on the tube rack (at about 22Â °C); Tube A4 and B4 were placed into an ice bath at 0Â °C. All test tubes were kept at different temperatures for 10 minutes. Meanwhil e, a control group of starch solution was prepared without amylase. (Bio Lab Manual, 2013) At the same time, a test plate was added 2 drops of I2KI reagent (1% Iodine and 2% KI) from Carolina Biological Supply Company per well. After 10 minutes, when test tubes were still in the original environments, solutions in Tube A1 with B1 were mixed and a timer was started. At each 30-second-inteval, a drop of the mixture was released into the well on the test plate until the solution in the plate did not change into dark blue and remained brown, indicating the end of the reaction by showing no presence of starch and presence of maltose and glucose. The experiment was repeated on the tubes at other temperatures. Slow reactions were observed and recorded up to 420 seconds due to time limit.
