Introduction: Replacingfuel oil with natural gas in brick kilns is one of the effective ways to reduce air pollution as well as the cost of the furnaces maintenance. The aim of this study isto estimate reduction of air pollutants resulting from brick kilns functioning with natural gasin Yazdprovince. Methods: In this descriptive-survey research, we estimated consumption of the fuel oil in the ...
a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
running the industrial components at a proper temperature is always a big challenge for engineers. internal combustion engines are among these components in which temperature plays a big role in their performance and emissions. with the development of new technology in the fields of ‘nano-materials’ and ‘nano-fluids’, it seems very promising to use this technology as a coolant in the internal c...
the primary objective of this work is to introduce a gear ratio selection strategy for a CVT equipped vehicle and show its effectiveness on the fuel consumption reduction. AFuzzy control algorithm is designed for this purpose. Anonlinear model is developed for simulating the longitudinal vehicle dynamics with accelerator pedal applied by the driver as an input. In order that pedal input valu...
Fleet fuel consumption is greatly reduced through the introduction of the HSDI Diesel engine. The reduced fuel consumption is then reflected in a reduction of CO2 emissions. The drop in fuel consumption and CO2 emissions results in a rise in market acceptance, which is also the result of desirable driving performance and greatly improved NVH behavior. The continuously increasing demands on plac...

In Iran, energy consumption in the building accounts for about 40% of the total energy consumed in the country; given that 71% of the natural gas consumption in the building is used for indoor heating; therefore, optimizing fuel consumption in the heating system is of special importance. This paper investigates the combined effects of climatic conditions and construction materials. For this pur...
in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
