Stakeholders argue that the information barrier is the major obstacle restricting firms from adopting Energy Efficiency Technologies (EETs) in Europe. The present work examines the processes of information gathering as regards to EETs and explores the factors affecting the level of acquired information by EET adopters. Empirical evidence is provided by a data set of Greek manufacturing firms wh...
In the present paper, a complete literatures review of thermal barrier coating applications in diesel engines is performed to select a proper type and to find coating effects. The coating system has effects on the fuel consumption, the power and the combustion efficiency, pollution contents and the fatigue lifetime of engine components. Usually there are several beneficial influences by appl...
Background and aims: One of the innovative technologies for air pollution control is non-thermal plasma. The dielectric barrier discharge reactor is one of the reactors that applied in non thermal plasma technology for air polluation control. In dielectric barrier discharge reactor, the distance between the electrodes for electric discharge is low and led to increasing space velocity of the pol...
Hydraulic fracturing and matrix stimulation are two major methods of the reservoir stimulation. Hydraulic fracturing, which is the newest technique and technically more complex, is very useful in low permeability reservoirs. Although it has been used widely in hydrocarbon production wells, it is a new method in Iran. In this paper, the effect of sufficient barrier layers on hydraulic fracturing...
We present the results of picosecond time-resolved photoluminescence (PL) measurements for GaN/A1Ga1N MQWs with varying structural parameters, grown by metalorganic chemical vapor deposition under the optimal (iaN-like growth conditions. We have shown that the optimal GaN/A1GaN (x 0.2) MQW structures for UV light emitter applications are those with well widths ranging from 12 and 42 A and barri...
An autostereoscopic display with parallax barrier attached onto a liquid crystal panel suffers from the trade-off between brightness and crosstalk. One approach for making improvement by modifying the layout of light blocking components, such as thin film transistor, storage capacitor, and protrusion, in the liquid crystal pixel has been proposed. Ray tracing simulation shows that the aperture ...
