EXAMPLE OF TECHNOLOGY MICROWAVE OVEN It is a machine that cooks food using microwaves‚ a type of radio wave. The microwave oven uses a magnetron. This is similar to a radio transmitter. It makes very short radio waves which go right into the food to a depth of about 2.5cm. This makes water molecules swing to and fro at about 2.5 billion times a second. This heats up the molecules around it. As they heat up the heat goes to the inside of the food. This process is called conduction. This also

accomplish these goals‚ we conduct two experiments. First‚ we measure UDP and TCP data throughput using Iperf measurement tool at different locations in Boelter Hall. Second‚ we measure UDP and TCP data throughput in Lab with and without effect of microwave turned on. For the first part of experiment‚ where we perform TCP and UDP throughput vs. Signal Strength as distance varies‚ I observed that as the distance increases‚ the value of both UDP and TCP data rate decreases. At a 30ft distance from

She has a pressing deadline to meet – the executive board is meeting in Paris tomorrow to review her choices. 1. What should Gagné do? Specifically‚ which projects should she fund and why? How should she handle the executive meeting? In the short term there are several projects Le Petit

projects on the table. This overflow has led to missed deadlines and therefore missed profit. The gap between LPC and other microwave manufacturers is closing fast and action is required. Essentially‚ Le Petit Chef needs a cornerstone development. There are five proposed projects: A new intelligent (fuzzy logic) line of microwaves‚ a low-cost version of an existing microwave line‚ an entirely new low-cost line‚ a quick heating model‚ and a larger cavity Liberté. When choosing which projects to fund

1. What were the order winners/order qualifiers for Galanz in the microwave oven business during the early stage of its development? Quality is one of most important factors for order qualifiers because it provided reliability for customers to use them. However‚ the low-price strategy was the order winner during the early stage of development of Galanz. To win orders‚ Galanz adopted a low-price strategy. Low product prices which can be afforded by domestic market triggered more demand. With

1. INTRODUCTION Capsicum (“Capsicum annum L.”) also known as peepers are one of the most important commercial crops in India belonging to the family Solanaceae. In India‚ only two spices viz. capsicum annum and capsicum frutsecens are known and most of the cultivated varieties belong to capsicum annum. It was introduced in India by the Portugese in Goa in the middle of 17th century. Capsicum is cultivated for vegetable‚ spice‚ and value-added processed products which has an important constituent

the WPT system. Typical WPT is a point-to-point power transmission. For the WPT‚ we had better concentrate power to receiver. It was proved that the power transmission efficiency can approach close to 100%. We can more concentrate the transmitted microwave power to the receiver aperture areas with taper method of the transmitting antenna power distribution. Famous power tapers of the transmitting antenna are Gaussian taper‚ Taylor distribution‚ and Chebychev distribution. These taper of the transmitting

Microwave Synthesis of 5‚10‚15‚20- Tetraphenylporphyrin Abstract: In this green chemistry experiment of 5‚10‚15‚20-tetraphenylporphyrin was synthesized from benzaldehyde and pyrrole. using microwave irradiation to heat the reactants.‚ The liquid reactants are absorbed on a solid support‚ silica gel‚ which acts as a Lewis acid catalyst to facilitate the reaction. The reaction forms a porphyrinogen‚ which is then oxidized to the porphyrin product by atmospheric oxygen. Column chromatography is performed
