Stimulated emission in the Nd:YAG laser with a saturable absorber Cr:YAG is modelled as a superposition of interacting optical modes which are stable in a given optical cavity. The interaction of the active laser crystal and a passive Q-switch with diode pump and optical cavity modes is modelled...

In this paper we analyze the determinants of the export performance firms. The methodology used is reminiscent of that of previous studies. The main novelty is the use of information provided by a specific field work done to effect. The analysis shows that export propensity is growing the more...

This paper deals with the promotion of green electricity (e.g. electricity based on water, wind, waves, solar, biomass) in electricity consumption. It considers various market mechanisms such as taxes, subsidies, CO2 quotas and green certificates.

Strategic plans in the energy sector have the overall objective of the use of renewable energy, especially wind power, hydroelectricity, biomass intending a considerable increase in the share it has in total energy production. Thus, chase is moving towards an economy based on low carbon...

Using solar energy through photovoltaic systems implementation in an agricultural household leads to the increasing of it’s efficiency, to optimizing energy balance thus implying the decreasing of the primary energy costs. The solar energy refers to a renewable energy source that is produced...

This study investigates the transformative effect of unscheduled solar PV and wind generation on electricity demand. The motivations for the study are twofold, the poor medium term predictions of electricity demand in the Australian National Electricity Market and the continued rise in peak...

The expansion of wind-generation in the United States poses significant challenges to policy-makers, particularly because wind’s intermittency and unpredictability can exacerbate problems of congestion on a transmission constrained grid. Understanding these issues is necessary if optimal...

This paper examines the China’s coal chemical strategy. As a part of national energy strategy, China’s coal chemical industry induces conflicts on technical level, economic level and policy level. The analysis of this paper is under the policy framework and discusses the causes and effects...

The expansion of wind-generation in the United States poses significant challenges to policy-makers, particularly because wind’s intermittency and unpredictability can exacerbate problems of congestion on a transmission constrained grid. Understanding these issues is necessary if optimal...

This paper uses a sample of 36 countries for the time period 1990-2011 in order to examine the relationship between countries’ electricity consumption from renewable sources and Gross Domestic Product (GDP) levels. Several nonparametric techniques are applied to investigate the effect of...
