laser fusion simulations are carried out for dt and d- he pellets by using a hydrodynamic code including heating from all charged reaction products and neutrons. it is shown that the inclusion of the side reactions and heating from all reaction products in the fuel pellets have an appreciable effect on the plasma temperature, the icf drive energy requirement, fusion gain and the ignition condit...

castor bean (ricinus communis l.( with a capability to withstand harsh conditions, low nutritional needs, 50 percent of oil content and high- quality, is one of the best crop used to produce biodiesel. the first step toward introduction and widespread cultivation of this crop is to investigate the energy balance for its cultivation. to do so, energy input (include renewable and nonrenewable) an...

In recent years, brain tumors become the leading cause of death in the world. Detection and rapid classification of this tumor are very important and may indicate the likely diagnosis and treatment strategy. In this paper, we propose deep learning techniques based on the combinations of pre-trained VGG-16 CNNs to classify three types of brain tumors (i.e., meningioma, glioma, and pituitary tumo...

introduction the high energy consumption is one of the serious problems in poultry industry. the poultry industry consume about five percent of total energy sources in different countries, with consideration of losses, it increases up to 16-20%. in the year 2003 also, the iranian chicken meat consumption per capita was 13.3 kg, while in the year 2013 it increased to 25.9 kg (fao, 2014). it show...

The radiation power loss from a magnetically confined plasma in a stellarator has been calculated using neoclassical particle and energy fluxes in an energy balance equation. We could obtain a power loss of about 34% of the total input power by numerical calculation. This fraction of the power loss has been found to be in good agreement with the experimentally measured values of 30-40% for...

Ever since the inception of the Personal Computer, the goal of its designers was to empower individuals to work with information in new, unprecedented ways. Today’s multimedia systems have advanced this idea to a new level, with their technical prowess to process a vast array of media types, increasingly so in real time. Why is it, then, that the user interface provided to interact with this ex...
