International Conference on Emerging Trends in Engineering and Technology‚ ICETET-09 Adsorption Air-Conditioning (AdAC) for Automobiles Using Waste Heat Recovered from Exhaust Gases A C Deshpande‚ R M Pillai Abstract- According to a cautious estimate‚ approximately 10% of the energy available at the crankshaft in a diesel operated vehicle is used for operating the compressor of the vehicle’s air-conditioning system. This is a huge loss if one takes into account the fact that the thermal efficiencies

A BASIC STUDY ON SIMULTANEOUS HEATING WITH MICROWAVES AND ULTRASOUND USING COAXIAL‚ TYPE APPLICATOR Abstract- A new heating method for hyperthermia using microwave and ultrasound simultaneously is proposed‚ and temperature distributions are obtained by computer simulations. The results have shown that the simultaneous use of microwave and ultrasound can heat wider and deeper region than the sole use‚ and can reduce the input power of microwave and ultrasound. This implies that we can reduce

The amount of heat and moisture are gained from the building internal and external heat sources that is required to be removed by the building cooling system. Both heating and cooling loads form the basis in designing the HVAC systems for the building and occupied spaces to achieve both

Air Defense Artillery is a very important part of The United States Army. Air Defense was a great asset during the Battle of Luzon. The 200th Coast Artillery Regiment provided Air Defense on the Islands of the Philippines for the Filipinos and United States Forces retreating. The United States and Philippine forces provided weapon systems and defense layouts for threats that were encountered. This encounter led The United States Army to replace old weapon systems with new weapon systems‚ and

History of Aerial Photography Dark Room in a Hot-Air Balloon The first known aerial photograph was taken in 1858 by French photographer and balloonist‚ Gaspar Felix Tournachon‚ known as "Nadar". In 1855 he had patented the idea of using aerial photographs in mapmaking and surveying‚ but it took him 3 years of experimenting before he successfully produced the very first aerial photograph. It was a view of the French village of Petit-Becetre taken from a tethered hot-air balloon‚ 80 meters above

The purpose of this differential heating lab is to see which of the given materials would heat up faster or remain the same when heated by our heat lamp. in previous years‚ when this lab has been conducted for the most part‚ results were the same as our results. Our background knowledge consisted of knowing about which of the given materials were more flammable. Hypothesis: if differential heating occurs‚ then different materials will heat at different rates. I would assume that the leaves

Since the invention of air planes few decades ago‚ air travelling has become famous among travellers. When the air transportation was first introduced in 1903 by the Wright Brothers‚ many people could not travel using it because it was expensive. But after few decades‚ technology has improved and air transportation is being widely used all around the world. Most of the countries has built airports and has their own airline companies. Today‚ due to rivalry among airline companies air travelling has become

Background information of AirAsia History The airline was established in 1993 and started operations on 18 November 1996. It was originally founded by a government-owned conglomerate DRB-Hicom. On December 2‚ 2001‚ the heavily-indebted airline was purchased by former Time Warner executive Tony Fernandes’s company Tune Air Sdn Bhd for the token sum of one ringgit. Fernandes proceeded to engineer a remarkable turnaround‚ turning a profit in 2002 and launching new routes from its hub in Kuala Lumpur
