A system for the rapid prototyping of floating point hardware designs is presented. This system, called Float, consists of a floating point class for the simulation of quantization effects associated with low precision floating point operators; an optimizer which can automatically determine the minimal number of exponent and fraction bits required for a specified degree of accuracy; and a param...

Bulk metallic glasses (BMGs) deform irreversibly through shear banding manifested as serrated-flow behavior during compressive tests. The strain-rate-dependent plasticity under uniaxial compression at the strain rates of 2 × 10, 2 × 10, and 2 × 10·s in a Pd-based BMG is investigated. The serrated flow behavior is not observed in the stress-strain curve at the strain rate of 2 × 10·s. However, t...

Optimizing the output power of a photovoltaic panel improves the efficiency of a solar driven energy system. The maximum output power of a photovoltaic panel depends on atmospheric conditions, such as (direct solar radiation, air pollution and cloud movements), load profile and the tilt and orientation angles. This paper describes an experimental analysis of maximizing output power of a photovo...

This paper describes the development stages and performance of a solar powered thermoelectric refrigerator. It is carried out by installing a conventional thermoelectric refrigerator in a stand alone photovoltaic system for household usage. This photovoltaic driven refrigerator is powered by a field of solar panels, a battery bank, a solar charge controller, and an inverter. In this project, th...

Renewable energy generation systems, based on photovoltaic sources, currently represent the most suitable solution, for low power levels, to reduce the energy consumption produced by oil and gas. Moreover, they are becoming more and more attractive as the price per watt of the photovoltaic modules is decreasing. However, the conversion efficiency of commercial photovoltaic modules is still rath...

We describe the development of new, Web-based maps of insolation and photovoltaic energy potential across Canada. The maps will be made available on the Natural Resources Canada website. They are presented for each month and summed for the entire year, for five different surface orientations: a suntracking orientation and four fixed South-facing orientations with latitude, vertical and latitude...

Offshore photovoltaic energy is possibly the most important future step in harnessing of solar energy. Since no long-term offshore installation exists to date, various unknowns are still present, creating a research gap. For instance, floating structures will have some type response incoming waves. This highly dependent on design structure. effect insolation systems installed structures. presen...

The paper presents grid-tied PV monitoring system using wireless sensor networks. The temperature and humidity parameters were measured using DHT22. While ACS 712 5A current sensor and Arduino voltage sensor modules were used to measure photovoltaic output current and voltage respectively. Web application has been developed in the base station using PHP programming web server to access the sens...
