Thermoeconomic Analysis and Optimisation of Air-Based Bottoming Cycles for Water-Free Hybrid Solar Gas-Turbine Power Plants (Mechanical Project)

The growing worldwide energy demand and the impacts of climate change due to anthropogenic greenhouse gases emissions are among the major issues facing humanity. The global energy system, responsible for most of the greenhouse gases emissions, is therefore at the heart of Continue reading

Subwoofer Frequency Response Optimization by Means of Active Control (Electrical/Electronics Project)

ABSTRACT

Most subwoofer systems have difficulties producing frequencies in the low end of the hearing spectrum due to the added power requirements and instabilities. Active controls can transform the audio signal without changing physical characteristics and Continue reading

A Single-Stage Grid Connected Inverter Topology for Solar PV Systems With Maximum Power Point Tracking (Electronics – IEEE Project)

This paper proposes a high performance, single-stage inverter topology for grid connected PV systems. The proposed configuration can not only boost the usually low photovoltaic (PV) array voltage, but can also Continue reading
