Abstract:
The solar photovoltaic (PV) system generates both electrical and thermal energy from solar radiation. In this paper, an attempt has been made for evaluating electrical output of solar PV panel installed at Ajat Instruments Nigeria Limited, Mokola, Ibadan, Nigeria. Using the first law of thermodynamics, energy/power analysis was performed. The operating and electrical parameters of a PV array include PV module temperature, open-circuit voltage, short-circuit current, fill factor, etc. were used. The reviewed formulas were used for the calculation of the energy/power efficiency of the PV system. Ene

Abstract:
Each subsequent generation of wireless standards imposes stricter spectral and energy efficiency demands. So far, layered wireless transceiver architectures have been used, allowing for instance to separate channel decoding algorithms from the front-end design. Such an approach may need to be reconsidered in the upcoming 6G era. Especially hardware-originated distortions have to be taken into account while designing other layer algorithms, as high throughput and energy efficiency requirements will push these devices to their limits, revealing their non-linear characteristics. In such a context, th

Rapid technological advances across a variety of industries are enabling society’s quest for sustainability. The resulting “Energy Transition” is causing an unprecedented shift in how the world’s population consumes energy and natural resources, driven by a range of factors including decarbonisation, economics, access to energy, societal expectations around environment and climate, energy efficiency, political and regulatory forces and emerging technologies. The “Energy Transition” will occur at different speeds and shapes in different geographies, depending on local economic and societal pressure

The decarbonization of the electrical grid requires advancements in affordable, long-term energy storage to address the intermittency of energy sources like solar and wind, while the continued decarbonization of the transportation sector necessitates advancements in energy dense storage devices such as batteries, with low cost and made from abundant materials. Alkali metal-oxygen batteries can provide greater specific energy than Li-ion batteries and can potentially lower cost by reducing reliance on late transition metals like nickel and cobalt.

The collocation method is the method for the numerical solution of integral equations and partial and ordinary differential equations. The main idea of this method is to choose a number of points in the domain and a finite-dimensional space of candidate solutions. So, that solution satisfies the governing equation at the collocation points. The current paper involves developing, and a comprehensive, step-by step procedure for applying the collocation method to the numerical solution of free vibration of tapered Euler-Bernoulli beam.

Introduction. Two-phase pulse width modulation in "the converter – electric motor" system is considered. It is noted that two-phase voltage modulation, which is implemented on a set of two electronically-key half bridges, finds important practical application. Restrictions are given on the values of the modulating functions of the potentials of the keys of the half-bridges, violation of which leads to intermodulation. Intermodulation leads to the appearance of low frequency harmonics in the composition of voltages and is the reason for a decrease in the energy efficiency of "the converter – elect

Although phosphorescent organic light-emitting diodes can have 100% internal quantum efficiency (IQE), the IQE usually roll-off at high current densities due to triplet-triplet annihilation. Phosphor-sensitized fluorescence can realize the energy transfer between phosphorescent and fluorescent emitters, and can used to suppress the efficiency roll-off and tune the color of the device. Based on this consideration, white emission including different colors of phosphorescent and fluorescent emitters can be expected.
