i) Description: • NFC is a short form for Near Field Communication‚ a technology that allows similar or NFC enabled devices to communicate with each other either by touching or bringing them into closer proximity – all wirelessly and is usually done within not more than a few centimeters • The communication can also be established between a NFC device with an unpowered NFC chip‚ which is called as tag. For example a movie poster outside a theater. So in this case your Smartphone would be the initiator

One thing that uses magnetic fields is the electric motor‚ which is used in many household appliances‚ such as electric fans‚ microwave ovens‚ and other small appliances. In this instance the electric motor has an electric current‚ giving it also this magnetic field. An electric motor converts electricity into mechanical motion. Most electric motors work by electromagnetism‚ but motors based on electrostatic forces also exist. The overarching concept is that a force is generated when a current-carrying

Soldier Field I have never been astounded by such marvelous architecture until I laid my eyes on Soldier Field in Chicago‚ Illinois. Soldier Field seemed like a dragon‚ just engulfing everyone who was spectating the Mexico vs Bosnia game on May 2011. When I first laid eyes on the monstrosity‚ I was very intimidated. The thought of entering this behemoth marveled me and made me even more excited to enter and watch the Mexico soccer game that I was anxiously waiting for! Chicago itself is a marvelous

In Flanders Field Cold Commentary In Flanders’s Field is a war poem filled with emotions that probably relate to World War One. The strange thing this poem does not have a sort of morning/sad tone to it which was typical after the world experienced the horrors of World War One. This poem has a very strong feeling of fighting on and “hold [the torch] high”(12) feeling. This is due to a lot of different reasons. The most prominent is the fact that this poem seems to be from a single entity

one of the newest mobile technologies‚ called Near-Field Communications or NFC. The technology can potentially replace credit/debit cards‚ or in some cases wallets entirely‚ for today’s consumers. “The payment system can allow Google to offer retailers more data about their customers and help retailers target ads and discount offers to mobile-device users near their stores.” Google wallet is just one way that industry developers are using Near-Field Communication technology. In the “home of the future”

generates a magnetic field. For a long time‚ it has been suggested that Earth’s magnetic field would eventually weaken. The field can change over time and may even occasionally flip‚ causing the north to become the south and vice versa. Now‚ new research‚ published on July 28th in Nature‚ states that Earth’s weakening magnetic field is actually a sign that another flip is to be anticipated. It is important to understand Earth’s magnetic field We owe some much of our livelihood to the magnetic field surrounding

Paddy Field Fish Culture (also named Fish Culture in Paddy Field) Problem Identification: The bad harvest of paddy resulting in a high price of rice‚ accompanying with the low income of farmers. Problem Delineation: Firstly‚ the growth of paddy needs a mass of water to survive‚ and it is hard and cost to fertilizer and to sterilize the fields‚ especially in a rainy season. And manure is hardly to be absorbed sometimes. In addition‚ there are usually some problems with pests and weeds‚ which

What holds the complexes together: The set of ligands are held to a metal ion by largely electrostatic forces (although there really is a high degree of covalency). The forces arise from the positive charge on the metal ion and the electric dipoles of the ligands‚ whose negative ends are associated

Essay Assignment II Nov. 28th‚ 2012 Discuss whether the functional Magnetic Resonance Imaging (fMRI) is a new form of “phrenology”. Is it reliable enough to be used as evidence in court? After fMRI was first introduced‚ it has been under criticism that it is not hard science. The most common technique‚ the BOLD (blood oxygen level-dependent) fMRI‚ measures the increase in regional cerebral blood flow in response to increased metabolism‚ which is to be caused from heightened activity of neuron
