Abstract:

In this paper, we present an adaptive circuit design that is capable of increasing the effective size-ratio of combinational logic gates to extend the balanced operation in the subthreshold region as well as to maintain high performance at the nominal VDD. We optimize the sizes of the PMOS transistors in the pull-up network for minimum power dissipation and propagation delay over a wide range of supply voltage. In addition to the minimized energy operation, the dynamically adjustable gate size-ratio allows the gate to preserve a symmetric voltage transfer characteristic at both normal supply a

Abstract:

Energy security of the European Union is one of the most important parameters that determine the present and the future on the world's geopolitical scene. EU countries are characterized by: insufficient fossil fuels from their own sources, continuous increase in consumption and strict environmental regulations (which limit the use of coal and oil). From all of the above, it follows that the long-term energy security of the European Union can be ensured by increase of gas supply capacity and diversification of sources of supply.

Large-sized commercial customers like institutional complexes have put significant efforts to promote sustainability by establishing renewable energy systems at university campuses. This paper proposes the integration of a photovoltaic (PV) system, energy storage system (ESS) and e

Abstract:

In today's power-driven world, ensuring uninterrupted electricity supply is crucial for both residential andindustrial sectors. This project focuses on designing an automatic power supply control system capable ofswitching between four different sources: mains supply, wind energy, solar energy and batteries. The systemprioritizes these sources based on availability and pre- defined criteria to maintain continuous power deliverywithout manual intervention. Using microcontroller-based logic and relay mechanisms, the setup monitors eachsource's status in real-time and seamlessly transitions betwe

Abstract:

The continuous demand and usage of energy in large quantum for industrial purposes has motivated the global advocacy for energy sustainability (SDG-7). Against this backdrop, this study employed various econometric techniques to study the nexus between clean energy supply in Nigeria and industrial development between 1990 and 2019. This study sets to establish the nature of the relationship in the long run, direction of causality and the stochastic dynamic interaction between clean energy supply and industrial development in Nigeria. Consequently, the following findings emerged from this study

With the continuous development and utilization of Marine resources, the island’s developments get more and more attention of the state, however, the island's power supply is always a bottleneck restricting the development of its economy. Microgrid as a kind of effective supply and use of distributed generation of power system, provides an effective solution for remote island power supply. There is a big difference in output characteristic from the power system, for the distributed power mostly use power electronic interface, which provides barriers to the protection of microgrid.

By making use of a back supply of heated rendering-plant fat to the continuous disc drier KDS 250 the so-called fritting effect is induced speeding up the evaporation of residual water and reducing the redrying time of the meat and bone paste. An analysis proved a reduced consumption of specific energy, whereby the demand for the best available technique (BAT) is met.

Abstract:

The design of a solar thermal installation is based on the lowest irradiance levels that occur during winter. However, there are consecutive days with irradiance levels well below those used for the design, which are called in this work “critical irradiance levels”. To solve this challenge, a statistical analysis is carried out to find a representative percentile of 22 years of consecutive days with “critical irradiance levels”. A case study of a cotton-dyeing industrial process requires 18.5 m3 of hot water and operates for 2.75 h at temperatures between 40 and 90 °C. Environmental variables
