Iii Rewrite

Check and correct my answers?

Let p, q, r denote the following propositions: p: Seng gets a grade A in maths q: Seng makes all the problems r math: Seng leads the class in math Write the following statements in symbolic form: (i) receive a degree in mathematics Seng, but it does all the math problems. (This one does not know how to …==) (ii) If Seng not all math problems, then he will have a degree A and the top of the class in mathematics. (My answer is q – p ∧ r>) [Is my answer correct? If wrong, please correct me, thanks.] (Iii) as part rewrite (ii) without using the connective if … then. (My answer: If and only if Seng not all math problems, get a degree A and the top of the class in mathematics. [My answer? If wrong, please correct me, and politely explain why my answer is wrong. Thanks ..]

(I) Seng gets a grade A in mathematics, but he does all the math problems. Seng gets a grade A in mathematics p → is true it does all the math problems is false → → q ~ Q is true. The relationship here is "and" – so this is the statement p ~ q. (Ii) If Seng not all math problems, then he will have a grade A and the top math class. Depending on the order of operations, I guess I do not remember exactly …. so I think that parentheses are necessary. q → (p ∧ r). (Iii) A → B is false if and only if A is true and B is false. Therefore, A → B is true if and only if B is true or A is false. That is, (A → B) ↔ (~ A ˅ B). Thus, a rewriting of (ii), is (O) Seng will do all the math problems or get a higher grade and math and math class. Hope this helps. ♣ ♣

RFID Markets Part III

Continuing from the second part, we talked about some of the vertical markets in which RFID can be used.

Economic Sectors

It is believed that top three fastest growing economic sectors in order of importance are: services retail, healthcare and business services.

The commercial and industrial applications of RFID are among the largest, with inventory management, safety and security to be more prominent. The harsh environmental conditions typical of manufacturing environments where RFID can be an advantage over other technologies.

Examples of Applications – product identification, inventory control raw material, product handshake, work in process and asset management – Especially when reusable containers are used for the transport of hazardous substances. Here, the rewritable tags can be used to record the contents of containers in order to facilitate the necessary processing.

Retail and Consumer Goods

Traditionally, the use of RFID in retail systems has had minimal use but is quickly about to change, with large supermarkets to the head. The retail industry and consumer goods is largely responsible for RFID pilot projects currently underway and see RFID adoption as a way of limiting the lack of stock, allowing visibility of the supply chain in Real Time or almost real time and reduce costs.

Examples of applications – automatic gearboxes, product identification, inventory management, asset management, theft prevention, promotion and customer service, returns management and retirement.

Library / Books / DVD rental

Library and library systems are big users of electronic article surveillance (EAS), which strictly speaking are not RFID, as it only can be used to detect the presence or absence of an article and not identified. EAS systems are beginning to be replaced by RFID, which can achieve the function of anti-theft and distance Combined data capture in an inventory. This is similarly applicable in the DVD rental market.

Application examples – auto loans and return control of theft, item identification, inventory management.

Life Sciences – human, animal sciences, medicine, life is one of the most long and is currently setting the fastest growing markets for RFID systems. Traditional applications such as animal tagging, has helped to develop this area. Also, more recently arrested and labeling of baby is a growing segment. However, medical and pharmaceutical applications can overcome these more traditional uses as regulatory requirements for traceability and increased pharmaceutical try to improve the means of protecting their investments.

Examples applications – patient identification (tags wrist band), item identification, verification of product authenticity, inventory management, asset management, performance and memory management.

Military

The U.S. Army is currently one of the largest users and markets great for RFID systems, but most systems require / use expensive active RFID tags, some with sensor capabilities. There is an obvious need for low cost RFID, especially for use in the management of food and medical supplies.

Examples of applications – item identification, inventory management

The airline industry

The airport and airline industry are experiencing and using RFID for many applications. For example, Boeing is using RFID to track and manage its aircraft parts, while others such as Hong Kong International Airport is using a automated in-flight catering for the route of in-flight meals and the management of returnable containers. The greatest potential application within the industry is to label luggage. Airlines are reported to handle approximately 3 billion bags each year and due to limitations of barcode technology is estimated that 2% of bags are lost each year, representing 60 million bags missing. Each bag costs lack airlines as much as $ 200 for replace, costing the industry about $ 12 billion per year plus the additional problem of dissatisfied customers.

Examples of applications – labels in baggage and management, parts identification / management and asset management.

Automotive Industry

RFID is a mature technology in the automotive industry and has established itself as an integral part of flexible manufacturing systems for those at the forefront of technological development, with greater penetration of vehicle safety systems (immobilizers) was adopted. The industry is researching additional uses of technology and management supply chain similar to other industries.

Examples of applications – Point and parts identification, product handshake, inventory management, management of assets, work processes, returns, and memory management. logistics industry in the logistics sector is in storage and postal services, transport road, fleet management and more. Worldwide the independent logistics industry is a late adopter of RFID although this is currently being addressed. Postal services are paying an active interest in RFID, particularly for item management (auto-routing, etc), as well as logistics service providers.

Examples of applications – item identification, inventory management, asset management, profitability and memory management.

Business Innovation

RFID can provide the basis for product developers to create new products, which have the ability to process and communicate information to other objects or devices, described as "silent trade" or "environmental trade." With the functionality added sensor technology, these objects or devices will be able to detect and respond to their environment, demonstrating a degree of intelligence, providing a greater return on investment.

Conclusion

It is evident that RFID technology is flexible and has potential for application in all industry sectors. Common to all industries is its use for identification of items and management, highlighting the interest in technology supply chain applications. It seems that technology is moving beyond the traditional use niches such as baggage handling, rental item labels, point of sale systems, real-time location (RTLS) and Supply Chain Management. This last application is considered as the "murderer" application, because this segment has the greatest opportunity to achieve long-term income, supporting applications such as work in progress tracking, container tracking, from the cradle to-grave tracking, monitoring and management platform of articles that will drive growth.
