In view of the needs for energy minimization in the buildings sector, the design of cost optimal low energy buildings (LEB) in the Mediterranean area is of significant interest. The measures available to accomplish this task include the use of latest building technology and the customization of the design (climate, owner’s needs and requirements, user behavior, etc). The goals include the minim...

Thermoeconomic models, which combine the concept of cost in the field of economics and the concept of exergy in the field of thermodynamics, provide a possibility of optimizing complex energy-generating systems to achieve a best balance between thermodynamic efficiency and economic cost (including investment cost and operation cost). For the first time, operation optimization on a 300 MW coal-f...

The most promising method for micro scale energy scavenging is via vibration energy harvesting which converts mechanical energy to electrical energy. Using piezoelectric cantilevers is the most common method for vibration energy harvesting. Changing the shape of the cantilevers can lead to changing the generated output voltage and power. In this work vibration energy harvesting via piezoelectri...

cables have always been under consideration as a structural element because of important features such as large strength to weight ratios and long spans. their equilibrium analysis is an important issue in this regard. but this analysis involves highly nonlinear equations arising from large deformations and material nonlinearity. different methods have been under use for numerical analysis of s...

the need for simulation of human foot mechanism has made researchers and engineers move towards different patterns to describe this movement. in this regard, optimal solutions such as energy consumption, accuracy, etc. are of utmost importance. in this paper, efforts have been made to present a new solution by designing a fully two-dimensional six-bar mechanism with one degree of freedom so tha...

EXCESS (Execution Models for Energy-Efficient Computing Systems) is a European research project funded by EU FP7 2013–2016. The EXCESS project developed a holistic approach to energy optimization across the entire hardware/system software/application software stack. Targeting architectures and applications in both HPC and the embedded domain, its goal has been to bridge the gap between such sys...

We consider sensor networks where energy is a limited resource so that energy consumption must be minimized while satisfying given throughput requirements. Moreover, energy consumption must take into account both the transmission energy and the circuit processing energy for short-range communications. In this context, we analyze the energy-efficient joint routing, scheduling, and link adaptatio...

in this paper, the energy efficient resource allocation in noma-based heterogeneous cellular network(hcn) systems is investigated. since energy consumption and its limitations is one of the important challenges in fifth generation of cellular networks (5g), we propose a resource allocation problem which allocates power and subcarriers to multiple users to achieve the best system energy efficien...
