Production ramp-up appears to be the main challenge during the late phases of innovation processes: new product specifications have to walk along with new production processes and even new production facilities. Bringing new products to market at a required level of quality while meeting targeted time and cost, is the main goal of production ramp-up management. Literature stresses the importanc...
this paper presents a new observer-based control scheme for a class of nonlinear systems. in the proposed method, nonlinear observer and twisting algorithm controller are employed to realize a sensor-less control strategy for complex systems which makes use of non measurable process information instead of installing as many sensors as possible. due to lack of availability of the complex system ...
this paper presents the steady state behavior and maintenance planning of the bleaching system in a paper plant. the paper plant comprises of various systems including feeding, chipping, digesting, washing, bleaching, screening, stock preparation and paper making, etc. one of the most important functionaries of a paper plant, on which quality of paper depends, is the bleaching system, where rem...
breast cancer within incident of one million new cases each year has become one of the most common malignancies and leading cause of death among females. this disease is comprised of about 18% of women cancers. the availability of early detection and improved treatments may decrease the mortality rates which reflected in the united states and many other western countries. breast cancer in over ...

ethyl benzene used increasingly each year is the raw material of producing styrene monomer. this substanceis produced from benzene alkylation with ethylene or ethanol, depending on the availability and cost of rawmaterials. in this study benzene alkylation in the presence of ethanol in a catalytic fixed bed reactor inthree states of isotherm, adiabatic and non-isotherm-non-adiabatic is mathemat...
the construct of self-efficacy has received increasing attention in research over the past two decades. many studies have been carried out 1.3 significance of the study this study has pedagogical implications since improving students’ self- efficacy and autonomy is important for promoting actual performance on classroom academic tasks. in academic settings, it has been shown that self-effi...
horses and 1 from Cx. tarsalis mosquitoes. Notably, our sequence is distantly related to GQ287646, which was isolated from Culex spp. mosquitoes in Chaco, Argentina. The nucleotide sequence of the positive control VEEV-Tc83 is correctly placed in the VEEV clade. Clinical and laboratory fi ndings showed that the illness described here was compatible with viral encephalitis. Using a generic RT-PC...
