Screening and classification are performed for the separation of particles by their sizes. There empirical, phenomenological, numerical models predicting size distributions screening/classification products. This paper introduces a new algorithm same purpose, which partially mimics phenomenological models. The iteratively selects monosize fractions with pre-defined probabilities, then carries p...

Direct steam generation is a promising alternative to conventional heat transfer fluids for solar thermal power plants using linear concentrators because water and do not have chemical stability problems. The novelty of this study, an energy exergy (2E) analysis, was that it performed on several configurations conceptual direct plant with optimized Fresnel reflectors in Agua Prieta, Mexico coup...

Abstract This paper re-considers the foundations of particle size statistics. While traditional statistics consider their data as samples random variables and use methods classical mathematical statistics, here a sample is treated point process sample, suitable form recommended. The whole sequence ordered sizes considered variable in space. Instead distribution functions, intensity functions ar...

Many jurisdictions use net metering to record power exchanges between residential solar photovoltaic (PV) panels and the grid, thus valuing at electricity retail rate. However, if over billing period, production exceeds consumption, surplus remains freely available for consumption. In Wallonia (Belgium), combination of generous subsidies rooftop PV installation encouraged households set-up larg...

In many parts of the world, artisanal and small-scale gold mines (ASGM) employed numbers people compared to large-scale mines. The ASGM has been played a crucial role in poverty alleviation rural development, particularly developing countries. mined ore is crushed ground for beneficiation gold. grinding process involved size reduction blasted materials acquire minerals interest. This paper pres...

Grid-connected transformerless photovoltaic (PV) systems have become very popu- lar, due to their smaller size/weight, greater efficiency and lower cost. However, the common- mode voltage (CM) generated in power inverters causes leakage current, which according PV standards, must be limited. Among different methods limit modified LCL (MLCL) filter with passive damping is an efficient simple sol...

An alternative sensing solution is described to measure local magnetic hysteresis cycles through a laminated core. Due the reduced space gap separating two successive laminations, it impossible interpose usual oversize sensors (wound coil, Hall-effect sensor). In this study, issue has been solved by printing needle probe method for state monitoring and using micrometric Giant Magneto Resistance...
