Virtual reality (VR) is one of the most common technologies nowadays, which make a virtual environment exactly similar to the real environment. The purpose behind this is to test several issues (designing or manufacturin...

Abstract This article presents the use of image processing technique to study the effect of injection current on the optical power distribution and laser spot cross-section (profile) of semiconductor laser type (AlGaInP)...

Given the substantial contribution of coal-fired power generation to environmental pollution in South Korea, evaluating the effectiveness of policies in the electric power sector is essential. The South Korean government...

The main objectives of the study are to develop a generalized thermo-electromechanical model of a solid-state heat engine based on a Ni-Ti-Cu shape memory alloy for converting low-grade thermal energy (30-100 °C) into e...

Introduction. Three-phase pulse width modulation (PWM) rectifiers are widely used in modern power conversion systems due to their high efficiency, controllability, and ability to provide high-quality energy conversion. T...

 INTRODUCTION: The frequent occurrence of extreme natural disasters poses severe threats to power grids, necessitating robust emergency communication. Low Earth Orbit (LEO) broadband satellite networks offer a promising...

Abstract Accurate and reliable wind power forecasting models are essential for the optimal dispatch of power systems. However, existing methods still face several challenges, including ineffective signal decomposition, l...

Abstract Individual training programs are essential for healthy weightlifting. To investigate the adaptive response of vital functions and pupil diameter to olympic style weightlifting training performed in elite female ...

The purpose of this study is to justify the design parameters of spiral-vortex equipment ensuring energy-efficient desulfurization of flue gases from autonomous medium-capacity gas-piston power plants (GPPPs). The study ...

ABSTRACT Microorganisms are expected to play vital roles in the development of sustainable societies, but this idea is still poorly understood by the general public. In addition, it would also be important for the future...

This article presents operational data from turboexpander units (TEU) wherein a stable temperature gradient across both the turboexpander and the turbocompressor coexists with its power imbalance. A hypothesis attributin...

This study reports a new optically addressed spatial light modulator (OASLM) structure based on bilateral-sapphire substrates with an air gap that exhibits high-average-power laser resistance. The resistance of tradition...

This article examines how illiberal leaders’ behaviour towards the judiciary changes when they have a second chance in power. Drawing on Varieties of Democracy indicators for populist rhetoric and constitutional change...

The article is devoted to a little-studied side of authority, in particular the authorities of the President of Russia. Exploring the constitutional scope of power, we can say that the President of Russia has a sufficien...

Abstract With the increasing performance requirements for data acquisition in applications such as the Internet of things and artificial intelligence, analog-to-digital converters (ADCs) face stringent trade-offs among s...

Power plant projects are crucial to providing andining a reliable power system. Power plant projects, like other construction projects, often experience a problem of delayed completion of work known as time overrun, whic...

Nowadays, offshore renewable energy is seen more and more as an attractive alternative to onshore energy thanks to less space limitations and usually better weather conditions. However, the higher costs in installation a...

The incorporation of wind generation in microgrids is growing progressively. This integration can introduce problems in the dynamics and power quality of the electrical system due to the wind fluctuations. This work prop...

A energia eólica tem experimentado um exponencial e virtuoso crescimento no Brasil. De 2009 a 2012, nos seis leilões em que a fonte eólica participou, foram contratados 7 GW em novos projetos representando mais de 25 ...

Animals respond to environmental variation by exhibiting a number of different behaviours and/or rates of activity, which result in corresponding variation in energy expenditure. Successful animals generally maximize eff...

Por motivos não abordados neste artigo, projetos importantes sofreram atrasos em seus cronogramas, aumentando o risco de que, em futuro próximo, o Brasil venha a enfrentar uma crise de abastecimento de energia elétric...

Solar panels consist of photovoltaic cells which are identical to diode semiconductor devices. Photovoltaics have a special point which is usually called MPP (Maximum Power Point). At that point, the photovoltaic is in a...

O presente artigo analisa outra vertente (por vezes ignorada ou subestimada) do conceito de poder, o soft power, relacionando-o com o caso concreto de uma potência em ascensão: a China. Inicia-se por definir a noção ...
