"Energy consumption in European countries is increasing in significant amount each year. EU countries are becoming more concerned towards environmental safeguarding along with energy production. Wind and solar power have increased their market in many power systems in the recent decades and the main limitation is that they are greatly time dependent and are not available all the time to cope with ...

The fluids have been around us for as far as we know and it enabled us to cross the oceans, ride the winds, shortens the distances, and much more. Computational Fluid Dynamics (CFD) has extended our understanding of fluids. Until today, the analytical solution of fundamental equations of fluid mechanics is a million-dollar award (referred to Clay Mathematics Institute). As engineers, let's leave ...

With globalization and rapid technological-economic development accelerating the market dynamics, consumers' demand is becoming more volatile and diverse. In this situation, capacity adjustment as an operational strategic decision plays a major role to ensure supply chain responsiveness while maintaining costs at a reasonable norm. This study contributes to the literature by developing computationally ...

Prolonged 'cold' exposure poses numerous challenges for industrial operations, human survival, and living convenience. The impact of the cold cannot be quantified just based on temperatures; however, other factors such as wind speed, humidity, and irradiance have to be considered. Therefore, efforts have been made to develop combined indices, such as wind chill temperature (WCT), AccuWeather RealFeel® ...

Ice accretion has been a persisting issue in cold regions and poses a threat to onshore and offshore infrastructure, especially to sensitive equipment and personnel safety. Thermal infrared imaging (thermography) can be used as a non-destructive, non- invasive technique to determine the presence and thickness of ice over a surface. The paper presents early-stage experiment results with a FLIR® Lepton ...

This paper studies the capacitive coupling in a capacitive power transfer (CPT) system designed for charging applications. It proposes mathematical models using the conformal transformation for calculating air-gapped and underwater capacitance and verifies the proposed models using COMSOL multiphysics and measurements. The measured results show that we can achieve nano-farad capacitance ranges ...

With the associated environmental challenges and unsustainable patterns of construction, there is also notable awareness and willingness among the state bodies to adopt sustainability measures and practices in Kazakhstan. This study explores the drivers of and barriers inhibiting the adoption of sustainability paradigm in the construction context of Kazakhstan. The drivers and barriers were validated ...

In this paper we prove new continuous refinements of some Jensen type inequalities in both direct and reversed forms. As applications we also derive some continuous refinements of Hermite–Hadamard, Hölder, and Popoviciu type inequalities. As particular cases we point out the corresponding results for sums and integrals showing that our results contain both several well-known but also some new ...
