Ontology is used to annotate sensor network data and enhances its semantic, which is the motivation of Semantic Sensor Network (SSN). With the development of SSN, massive RDF datasets have been produced, so SSN is up against a big challenge now, i.e., the integration and application of data. In this paper, we present a Hadoop-based Semantic Sensor Network System (named HDSW) to achieve efficien...

Several factors can influence the process of biogas production. The type of reactor is one of the key factors that influence biogas production. Therefore, the aim of this study was to construct a portable horizontal polyethylene-based biogas reactor. In addition, the performance of the developed biogas reactor was tested through digestion of cow manure. The experiments were carried out in Mashh...

triazine derivatives are small synthetic peptides with no apparent toxicity and high target specificity in central nervous system. hippocampal tissue is the most vulnerable area in the alzheimer’s disease (ad). the aim of this study was to investigate the neuroprotective effect of triazine in ad induced by intra-cerebro-ventricular (i.c.v.) administration of streptozotocine (stz). male wistar, ...

conclusions as we can see the ann outputs values are very close to actual cu concentration, so indicating that predicted values are accurate and the network design is proper and the input variables well suitable for the prediction of cu concentration. background access to safe drinking water is one of the basic human rights and essential for healthy life. concerns about the effects of copper on...

one of the popular and well known models in boundary layer that is implemented in most of the operational and familiar models is the mellor-yamada model of atmospheric boundary layer. one reason that this model is so popular is its ability in simulations and exposing of different phenomena in the boundary layer. this model has been constructed based on second order closure hypothesis. beside al...

the spreading activation models of mental lexicon's structure have presented the lexicon in multiple layers (semantic- syntactic- phonological). each layer is a network of nodes which are associated by links. the nature of these links is different from layer to layer. the literature for english speakers has shown that in the phonological layer, phonological forms of words have been linked based...

investigation of soil properties like cation exchange capacity (cec) plays important roles in study of environmental reaserches as the spatial and temporal variability of this property have been led to development of indirect methods in estimation of this soil characteristic. pedotransfer functions (ptfs) provide an alternative by estimating soil parameters from more readily available soil data...

Objective: Soil temperature serves as a key variable in hydrological investigations to determine soil moisture content as well as hydrological balance in watersheds. The ingoing research aims to shed lights on potential of artificial neural networks (ANNs) and Neuro-Fuzzy inference system (ANFIS) to simulate soil temperature at 5-100 cm depths. To satisfy this end, climatic and...
