Abstract Background With the increasing concerns on energy shortage and carbon emission issues worldwide, sustainable recovery from thermal processes is consistently attracting extensive attention. Nowadays, a significant amount of usable wasted not recovered worldwide every year. Meanwhile, discharging often causes environmental hazards. Significant social ecological impacts will be achieved i...

The increase in the energy consumption of machines when operating unsteady modes is caused by many reasons, main which are deviation from calculated and braking machine with irretrievable losses. When driving cars electric motors, recovery can be carried out switching them to generator mode returning general power supply network. However, absence parallel consumers network requires presence an ...

CP measurements show that PBTI stress induced interface trap area density ΔNit in InGaAs/Al2O3 n-MOSFET is very small and has power law time evolution At in the stress phase, and is partially recovered in the recovery phase. However the DC Is-Vg measurements show large degradations of negative ΔVg and sub-threshold swing S in the sub-threshold region and are recovered in the recovery phase, als...

conclusions the results clarified a deep perception of participants’ experiences after disaster. the path of life recovery after disasters involves participants’ striving to achieve a comprehensive health recovery, which starts with the need for all-inclusive health recovery as a main concern; this is the motivator for a responding strategy. this strategy is participatory, and the process is pr...

This paper simplifies the energy regeneration based vehicle velocity system of the hydraulic hybrid bus into a process in which the extension rod of the hydraulic cylinder drives the secondary-element variable delivery pump/motor to change its displacement. This process enables braking of the vehicle and also allows recovery of energy. The stability, energy efficiency and other characteristics ...

Fluorescence resonance energy transfer (FRET) is an extremely effective tool to detect molecular interaction at suboptical resolutions. One of the techniques for measuring FRET is acceptor photobleaching: the increase in donor fluorescence after complete acceptor photobleaching is a measure of the FRET efficiency. However, in wide-field microscopy, complete acceptor photobleaching is difficult ...

various researches on laboratory and field scale illustrate that manipulating the ionic composition and the ion concentration of injected water can affect the efficiency of water flooding and the interaction of injected water with rock and other fluids present in porous media. the objectives of this paper are to investigate parameters that affect low salinity water flooding; mainly the effect o...

The power consumption of the clock tree dominates over 40% of the total power in high performance VLSI designs. Hence, low power clocking schemes are promising approaches for low power design. We propose energy recovery clocked flip-flops that enable energy recovery from the clock network, resulting in significant energy savings. These flip-flops operate with a single-phase sinusoidal clock whi...

This paper describes the context, the basic assumptions and the main findings of a joint research project aimed at identifying the optimal breakdown between material recovery and energy recovery from municipal solid waste (MSW) in the framework of integrated waste management systems (IWMS). The project was carried out from 2007 to 2009 by five research groups at Politecnico di Milano, the Unive...
