We proposed a short-term thermal energy storage system by applying Phase Change Materials (PCMs) in air ducts connected to an indoor conditioning unit within ceiling space. PCM tubes were arranged staggered layout the duct and cooled chilled from during “charging” mode, whereas released cold room space without operation of compressor “discharging” mode. The charging mode allowed for increase pa...

In recent years, the energy consumption of vehicles has gained widespread attention due to increasing importance and environmental issues. Coupled with explosive demand for vaccines that spawned massive deployment refrigerated trucks, savings efficiency improvement are goals pursued by pharmaceutical logistics companies while getting vaccine distribution task done. order evaluate fuel trucks du...

car body lightening and crashworthiness are two important objectives of car design. due to their excellent performance, composite materials are extensively used in the car industries. in addition, reducing the weight of vehicle is effective in decreasing the fuel consumption. hat shape energy absorber is used in car’s doors for side impact protection. the aim of these numerical models and exper...

Energy consumption is a fundamental barrier in taking full advantage of today and future semiconductor manufacturing technologies. We present our recent research activities and results on estimating and reducing dynamic and static energy under realtime constraints in embedded systems. This includes techniques and tools for (i) estimating instantaneous energy consumption of embedded processors d...

reducing energy consumption and greenhouse gas emissions have become a worldwide necessity. iran has the sixteenth ranking position of global greenhouse gas emissions and its rate of growth is above global average. built environments are responsible for about 40% of energy consumption and it is generally approved that the greatest portion of built environment is dedicated to residential land us...

Reducing energy consumption has become an important issue in designing hardware and software systems in recent years. Although low power hardware components are critical for reducing energy consumption, the switching activity, which is the main source of dynamic power dissipation in electronic systems, is largely determined by the software running on these systems. In this paper, we present and...
