preventive maintenance scheduling of generating units is addressed as a long-term scheduling in power system studies aiming to increase the reliability incorporating cost reduction. it consists of knowing which generating units should be shut down for regular safety inspection. in this paper, a new formulation of preventive maintenance scheduling associated with cost reduction index (cri) is pr...

this paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. the hybrid dc power sources are connected to grid using power electronic converters include dc-dc converter and grid connected voltage source inverter. the power from hybrid power sources is controlled during voltage sag by designing of control strategy for dc-dc converter....

context: detection of causative pathogen is crucial for treatment strategies in most infections. molecular diagnosis as a more sensitive and specific method, has become the best option to investigate certain pathogens, mainly viruses. recent scientific and technological approaches resulted in changing the area of diagnostic microbiology. evidence acquisition: a comprehensive online search of da...

paris polyphylla smith var. yunnanensis (liliaceae) is an important traditional medicinal plant of the yunnan province in china. however, the genomic information regarding this plant is limited. to further understand its molecular background, we conducted illumina hiseq 2000 second-generation sequencing of this plant species. approximately 30,198,679 reads with an average length of 202 bases we...

the current study investigated and compared data generation methods for groundwater modeling. thesemethods can be divided into two classes; geostatistic and probabilistic. by comparing geostatistic methods,the best method was chosen and the hydraulic conductivity of the aquifer was generated for a study area ina grid (9-cell) format. after observing weak spatial correlation between the data, th...

background: finding the right word is a necessity in communication, and its evaluation has always been a challenging clinical issue, suggesting the need for valid and reliable measurements. the homophone meaning generation test (hmgt) can measure the ability to switch between verbal concepts, which is required in word retrieval. the purpose of this study was to adapt and validate the persian ve...

entropy generation in an unsteady hydromagnetic couette flow of a viscous incompressible electrically conducting fluid between two infinite horizontal parallel plates in a rotating system have been analyzed. both the lower and upper plates of the channel are subjected to asymmetric convective heat exchange with the ambient following the newton's law of cooling. a numerical solution for governin...

given the importance of transcriptome analysis in various biological studies and considering thevast amount of whole transcriptome sequencing data, it seems necessary to develop analgorithm to assemble transcriptome data. in this study we propose an algorithm fortranscriptome assembly in the absence of a reference genome. first, the contiguous sequencesare generated using de bruijn graph with d...

deregulation policy has caused some changes in the concepts of power systems reliability assessment and enhancement. in this paper, generation reliability is considered, and a method for its assessment using intelligent systems is proposed. also, because of power market and generators’ forced outages stochastic behavior, monte carlo simulation is used for reliability evaluation. generation reli...

the new-aeds, whose developments were motivated following the discovery of the valproate and its marketing in the u.s in 1978, have presented more therapeutic options. there are approximately twenty four fda-approved antiepileptic drugs for use in patients with epilepsy, five of which were identified and have come on to the market between 2009 and 2012. the new-aeds are of interest, not due to ...
