What is the role of RFID chips in logistics? What is the role of RFID chips in logistics? Solution Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically stored information. Passive tags collect energy from a nearby RFID reader\'s interrogating radio waves. Active tags have a local power source such as a battery and may operate at hundreds of meters from the RFID reader. Unlike a barcode, the tag need not be within the line of sight of the reader, so it may be embedded in the tracked object. RFID is one method for Automatic Identification and Data Capture (AIDC).[1] The emergence of RFID (Radio Frequency Identification) technology has been greatly increased efficiency in the production process management, material flow management, logistics and transport, retail and distribution and other fields of the national economy industries, including electronic information industry. RFID may eventually replace the ubiquitous bar code in the future and become the main technology in logistics and supply chain management field RFID in Logistics Management Logistics management involves the efficient control of some or all of the supply chain functions, including: – Product research and development – Sourcing and purchasing – Manufacturing – Production planning – Sales, marketing, and forecasting – Inventory management – Cross-docking and flow-through – Customer service – Transportation – Freight payment – Information reporting Using RFID logistics tracking has helped many organizations solve the main challenge at every node in their supply chains: the lack of visibility of logistics data. RFID technology is a powerful solution that improves asset visibility, data quality, inventory management, and interoperability in an end-to-end integrated supply chain. In fact, the U.S. Department of Defense (DoD) issued a mandate in 2005 that requires all of their suppliers to use RFID in marking any items that are sold to the DoD. The need for this mandate arose from decades of logistical challenges faced by the military with regard to the supply chain. RFID has proven to alleviate various logistical problems associated with the DoD supply chain. RFID technology, in combination with the Internet, allows the DoD to disseminate accurate, real-time data to commanders worldwide so that assets can be easily located and used according to the Department’s highest priorities..

How does RFID work and differentiate with bar coding. Also what is the impact of RFID in B2B e-Commerce. Discuss Collaborative Commerce and its benefits Solution RFID stands for radio frequency identification tag associated with each products. The main difference between the working of RFID and Barcoding are as follows: RFID Working: In RFID method a tag is affixed to the products which is used to identify and track product via radio waves. These tags can store or carry upto 2,000 bytes of data. RFID technology has three parts namely the scanning antenna, a transceiver and a transponder. The transceiver comes with a decoder to interpret the data and the transponder comes with the pre-set with information.The scanning antenna is used to send a radio-frequency signal to the RFID tag. As the RFID tag is passed through the frequency field of the scanning antenna; it will be able to detect the activation signal and further will be able to transfer the information data it holds to be picked up by the scanning antenna. Bar Coding: A visual representation of data that is scanned and interpreted for information is called as barcodes. A certain code is present in each barcode which works as a tracking technology for products. It is usually represented as a sequence of lines or in other shapes. Barcodes initially were one dimensional and were based on the width and spaces between parallel lines but later they were developed as two-dimensional with many geometrical shapes used for bar-coding. The barcode technology can be scanned with the help of bar-code readers. Impact of RFID in B2B and E-Commerce are as follows: RFID has a great impact on the B2B and E-commerce business since the radio frequency codes can now be checked easily. RFID has playeda significant role in fostering a higher level of integration between the supply chain members. Collaborative Commerce: C-Commerce or Collaborative commerce is a new business strategy that looks at the supply chain managment in a difference way. It describes about the selection and project based cooperation between one or more parties or parteners along the supply chain. Collaborative commerce is further seen as a tool that combines knowledge management, supply chain management and e-commerce. Benefits of Collaborative Commerce are as follows: 1. Cost Advantages. 2. Concentration on core competencies 3. Innovations are encouraged 4. Reduction in inventory 5. Reduced time-to-market.

Radio-frequency identification (RFID) is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data, to automatically identify and track tags attached to objects. COMPONENTS: READER- Antennae are the conduits between the tag and the transceiver, which controls the system’s data acquisition and communication. The antenna emits radio signals to activate the tag and read and write data to it. 2. RFID TAGS- Passive tags do not carry onboard power and derive it from the reader to enable reading and writing to the tag. Active tags are where the controller is the interface between one or more antennae and the device requesting information from or writing information to the RF tags. 3. CONTROLLER- The controller is the interface between one or more antennae and the device requesting information from or writing information to the RF tags. There are controllers for interfacing antenna to PC servers and networks. Supply Chain Management (SCM) is the approach of managing the flow of goods and services – from raw materials to the end consumer. It involves all the activities and processes that transform raw materials into finished products and deliver them to the end customer. Encompasses: Planning Sourcing Production Inventory management Logistics Customer service BENEFITS: Increased Efficiency: Streamlined processes reduce waste and optimize resource utilization. Reduced Costs: Lower inventory levels, improved logistics, and better negotiation with suppliers lead to cost savings. Enhanced Customer Satisfaction: Faster delivery times, improved product quality, and better responsiveness to customer needs. Improved Competitive Advantage: Efficient SCM creates a strategic edge in a competitive marketplace. . Initial Investment Costs Data Security Concerns Limitations of RFID Technology Other Considerations: Not all products or packaging materials are suitable for RFID tags due to size constraints or compatibility issues. The shelf life and durability of RFID tags need to be factored in, especially for harsh environments. Potential impact on disposal or recycling processes for products with RFID tags. RFID technology is revolutionizing supply chain management (SCM) by enabling real-time tracking, improved inventory accuracy, and enhanced visibility throughout the entire process. From streamlined warehouse operations and efficient asset tracking to faster deliveries and reduced counterfeiting, RFID offers significant benefits. While initial investment and technical limitations require consideration, integration with AI and blockchain promises a future of intelligent and secure data management in global supply chains. By embracing RFID, businesses can gain a competitive edge and navigate the complexities of modern SCM. Read Range Tag Size and Compmodern SCM. Read R

A concerned mother brings her 2-year-old daughter to the clinic with the complaint of fever, irritability, and difficulty eating. Based upon what you have learned so far in class, what are possible diagnoses and how would you differentiate between them? Solution In children the symptoms of epiglottitis include fever with chills difficulty swallowing refusing to eat restlessness and irritability. This disease can be diagnosed by observing X-rays and the wind pipe laryngoscopy. The doctors day observed the swollen epiglottis by observing his throat. Blood test also help observed infection ,other immunologic test also help for identifying the antibodies to specific bacteria ore viruses. Epiglottitis maybe misdiagnosed as strep throat. other misdiagnosis include infectious diseases like diphtheria infectious mononucleosis, peritonsillar abscess. An important misleading diagnosis is croup which occurs in younger children having viral prodrome the children with croup has barking cough and rarely appears toxic they also it experience sore throat, dyspnea and vomitings. Epiglottis is very rare disease where as crop is very common epiglottis is caused by haemophilus influenzae type b virus ,croup is caused by parainfluenza, rsv and enteror viruses ,epiglottis is common in between the children 3 to 7 years where as crop is common between 3 months to 3 years. Fever is less in croup disease whereas fever > 39°c is observed in epiglottitis. Croup Is benign where as epiglottitis is potentially critical. Bacterial tracheitis may also mislead epiglottitis diagnosis..

Why is it important that chromosomes can cross over in Meiosis and not in Mitosis? Solution Crossing over results in genetic recombination. It is responsible for genetic diversity of the population. Genetic recombination and natural selection are the driving force behind evolution. Meiosis is called sex division, it is responsible for gamate formation. Crossing over occurs when chiasma is formed and this random exchange of information leads to unique gametes formation and genetic recombination to occur..

TDH invited staff fiom the Centers for Disease Control and Prevention (CDC) to participate in the ongoing investigation. CDC staff suggested submission of fresh stool specimens from ill students for viral studies including reverse transcriptase-polymerase chain reaction (RT-PCR). TDH and CDC staff decided to undertake an unmatched case-control study to further explore the source of the outbreak. Question 18 Who should be enrolled as subjects for this study? Solution persons with vomiting or diarrea that is the enroolled as subjects for this study.

1. In which case(s) is there constructive interference for two light waves meeting at the same point at a given instant? (Select all that apply.) A) Both waves are at their minimum B) One wave is at its maximum, one wave is at zero. C) Both waves are at their maximum D) One wave is at its minimum, one wave is at zero. E) One wave is at its maximum, the other is at its minimum 2. In which situation(s) is there destructive interference when two waves intersect at one point? (At an instant of time.) A) Both waves are at a maximum B) One wave is at a maximum, the other is at zero C) One wave is at a minimum; the other is at a maximum D) Both waves are at a minimum E) One wave is at a minimum, the other is at zero 3. When light goes through a very narrow slit, it spreads out from that slit in all directions beyond the slit due to: A) diffraction B) dispersion C) interference D) refraction E) reflection 4. Light encounters two very narrow slits closely spaced together. Constructive interference of light coming from these two slits will occur when A) the wavelength of the light equals the width of the slits B) the wavelength of the light equals the separation of the slits C) the light from one slit has to travel a distance that is longer than that traveled by the light from the other slit equal to half the wavelength of the light D) light from one slit at its crest encounters light from the other slit at its trough E) the light from one slit has to travel a distance that is longer than that traveled by the light from the other slit equal to twice the wavelength of the light 5. Equations 17.7 and 17.8 depend on which assumption? A) The screen is very close to the slits B) the slits are much wider than the wavelength of the light C) small angles (in radians) D) large angles (in radians) 6. You shine both red and blue light through a double slit. What can you say about their interference patterns? A) The red bright fringes will be closer together than will be the blue bright fringes. B) The red and blue bright fringes will be the same distance apart from each other. C) The blue bright fringes will be closer together than will be the red bright fringes. 7. You compare a double-slit interference pattern with the interference pattern due to a diffraction grating of the same spacing as that of the double-slit. The most noticeable difference would be that: A) The peaks of the diffraction grating are much broader than that for the double-slit B) The peaks of the diffraction grating are much farther apart than for the double-slit C) The peaks of the diffraction grating are much sharper than that for the double-slit D) The peaks of the diffraction grating are much closer together than for the double-slit E) The center point is a maximum, not a minimum F) The center point is a minimum, not a maximum Solution (1).Both waves are at their maximum (2).One wave is at a minimum; the other is at a maximum (3).diffraction (4).the light from one slit has to travel a dis.

List and describe three examples of secondary sexual characteristics each for males and females. Solution Secondary sex characteristics are features that appear at sexual maturity in animals and during puberty in humans, Secondary sex characteristics are Traits that distinguish the biological sexes of a species, but are not directly part of the reproductive system. Examples of secondary sex characteristics in humans include shorter stature and wider pelvis, breast development, and more fat in the thighs and buttocks in women and broader shoulders, greater muscle mass, more facial and other body hair, and “male pattern” baldness in men. Male secondary sexual characteristics of hair: The pubic regions is usually the first to develop hair Facial hair begins at the corner of the mouth and spreads to the midline - followed by the rest of the face Body hair develops long before facial hair growth is complete (arm pit, legs, arms, buttocks, back) Male secondary sexual characteristics of vocal changes: Rapid growth of the larynx - larger and stronger The thyroid cartilage increases in dimension creating the Adam\'s apple Vocal cords lengthen and thicken. Male secondary sexual characteristics of the body: Increase in body size, weight and strength (musculature) Correlated to increase in testosterone levels Female secondary sexual characteristics of hair: The pubic regions is usually the first to develop hair Body hair develops slightly later (arm pit, legs, arms) female secondary sexual characteristics of the pelvis: Broadens and changes from a narrow funnel-like outlet, to a broad oval outlet, flaring at the hip Fat cells increase in number around the buttocks and thighs Female secondary sexual characteristics of the breasts: Tanner Stages Tanner I no glandular tissue, typically age 10 and younger Tanner II Breast bud forms, with small area of surrounding glandular tissue, 10-11.5 Tanner III breast begins to become more elevated, and extends beyond the borders of the areola, 11.5-13 Tanner IV increased breast size and elevation, 13-15 Tanner V breast reaches final adult size, 15+.
