A new fuzzy maximum power point tracker (MPPT) for photovoltaic systems is proposed. Fuzzy controller input parameters dI dP , ) dI dP ( D and variation of duty cycle ( DC D ) are used to generate the optimal MPPT converter duty cycle, such that solar panel maximum power is generated under different operating conditions. A photovoltaic system including a solar panel, a fuzzy MPP tracker and...

Nel lavoro si descrive l’applicazione di tecniche di IA per l’elaborazione e l’allineamento di immagini provenienti da scanner 3D, in grado di generare modelli digitali tridimensionali. Al fine di allineare più correttamente i fotogrammi acquisiti, in scansioni successive, dal dispositivo e ricostruire accuratamente il modello tridimensionale digitale, si è integrata la tecnica di Simulated Ann...

background: the role of diagnostic pathology has become more prominent. this study aimed to compare the accuracy of frozen section compared with permanent section in the morning and afternoon working hours. methods: in this cross-sectional study, 99 patients with stage 1 and 2 breast cancer who underwent sentinel and non-sentinel lymph node biopsy between 2013 and 2015 were included. the result...

background and objectives: the addition of plasticizers (mainly phthalates and adipates) makes plastic flexible and popular for packaging, storing and preserving food, water, and so on. the most widely used plasticizer in food contact applications is di-ethylhexyl phthalate (dehp) though being suspected to have carcinogenic and estrogenic properties. the aim of this study is application of magn...

in this paper a numerical method for solving forth order fuzzy dierentialequations under generalized differentiability is proposed. this method is basedon the interpolating a solution by piecewise polynomial of degree 8 in the rangeof solution . we investigate the existence and uniqueness of solutions. finally anumerical example is presented to illustrate the accuracy of the new technique.

introduction: langerhans cell histiocytosis (lch) is a rare disease characterized by clonal prolifera-tion of histiocytosis in different tissues. permanent consequences (pc) described among subjects with langerhans cell histiocytosis (lch).in this study we report the prevalence of permanent sequel among long – term survivors of lch in our center. methods: we had 30 cases of lch from 1989 – 2001...

This paper presents the results of experimental work carried out to evaluate the distribution of cold and hot exhaust gas recirculation between cylinders in a DI diesel engine. The experiments have been conducted on a 3.99 liters turbocharged DI diesel engine under full load condition at 1900rpm in order to distinguish and quantify some effects of hot and cooled EGR with various rates on the EG...

dentinogenesis imperfecta (di) is a hereditary dentin defect caused by an autosomal dominant mutation in dentin sialophosphoprotein gene. defective dentin development results in discolored teeth that are prone to wear and fracture. early diagnosis and proper treatment are necessary to achieve better functional and esthetic results and minimize nutritional deficiencies and psychosocial distress....

this study was conducted to determine the effects of the combined use of rain shelters (rs) and deficit irrigation (di) on tomato yield and quality characteristics. two experiments with different treatments were conducted in the southern china during the growing season in 2011 and 2012. the crops were irrigated to field capacity once average soil water content at the 0-60 cm layer in the treatm...
