Power quality monitors handle and store several gigabytes of data within a week and hence automatic detection, recognition and analysis of power disturbances require robust data mining techniques. Literature reveals that much work has been done to evolve several feature extraction and subsequent classification techniques for accurate power disturbance pattern recognition .However the features e...

abstract: this paper considers the problem of scheduling n jobs on m unrelated parallel machines with sequence-dependent setup times. to better comply with industrial situations, jobs have varying due dates and ready times and there are some precedence relations between them. furthermore sequence-dependent setup times and anticipatory setups are included in the proposed model. the objective is ...

A strategy by multi-objective genetic algorithm (MOGA) combined with Kriging response surface is proposed for optimum design of wavy fin tube in an air cooler, while minimum pressure loss factor, maximum heat transfer factor and overall performance as three objective functions. The results show that the effects height density on are positive wave number angle negative; parallel higher than stag...

This action research consists two cycles with stages planning, action, observation, reflection. Data collection was done by observation techniques, tests, doc...

The microchannel heat sink (MCHS) has become the most relevant micro-heat exchanger for a small area in need of an effective high removal system. However, dissipation from microchips where MCHS is utilized—the microprocessor and microcontroller—is getting higher with sizes smaller. A more coolant needed to address increasing load microchip nanofluid, nanosized particles dispersed base fluid, am...

As a multi-source vibration machine, the complex of combine harvester has caused many effects on various components. In this paper, dynamic response plate and shell is studied, influence factors determined. The structure optimized, scheme structural optimization that replaces finite element model with surrogate developed. designed Latin hypercube design (LHD), surface generated based Kriging mo...

A través del concepto "cuerpo sin órganos", Antonin Artaud cuestiona el orden orgánico de la realidad, considerado por él pernicioso para sujeto y propia existencia. Gilles Deleuze retoma noción desarrollar su teoría acontecimiento diferencia, mediante ella genera una definición analítica deseo. Este artículo analiza diálogo entre dicho poesía española siglo XXI a tres poemarios: Cuerpo mí, Edu...

In this paper, we present the design and optimization of a centrifugal fan with requirements maximizing total-to-static pressure rise efficiency at two operating points maximum torque provided by motor power using 3D inverse method, DOE (design experiment) study, an RSM (response surface model) MOGA (multi-objective genetic algorithm). The geometry is parametrized 13 parameters, 120 different d...
