Energy labelling and minimum efficiency performance standards have proved to be very effective in stimulating energy efficiency improvement in the domestic appliance sector. But standards suffer from long and often difficult implementation periods because of the resistance of the industrial sector. As a consequence, the question has been raised as to whether similar results could not be obtaine...

BACKGROUND Prolonged controlled mechanical ventilation depresses diaphragmatic efficiency. Assisted modes of ventilation should improve it. We assessed the impact of pressure support ventilation versus neurally adjusted ventilator assist on diaphragmatic efficiency. METHOD Patients previously ventilated with controlled mechanical ventilation for 72 hours or more were randomized to be ventilat...

In this paper, efficiency analysis and design of contactless electric power transfer systems working based on an inductive method are elaborated. Large leakage inductances of the systems are compensated to achieve resonance conditions for maximum efficiency. Considering the circuit models of a contactless system, the effects of different parameters including the compensating capacitors are anal...

In electrical heating systems, the electrical power consumption should be lower than the Contracted Power Limit. Energy distribution devices are used to solve this problem, but they are only concerned with the electrical energy. We claim that this energy distribution must also consider the comfort level in the building. In this work, an electrical energy distribution MAS for coordinating the el...

Information technology (IT) has captured the popular imagination, in part because of the tangible benefits IT brings, but also because the underlying technological trends proceed at easily measurable, remarkably predictable, and unusually rapid rates. The number of transistors on a chip has doubled more or less every two years for decades, a trend that is popularly (but often imprecisely) encap...

soil temperature is one of the most effective parameters for plant growth. although the spatiotemporal monitoring of soil temperature is important for providing an optimum condition to maximize the yield efficiency, indirect measurements for zoning  of soil temperature are essential due to difficulties in direct methods of measuring it and also the limited measurement points. thus, the efficien...
