Biological assessment of river Haji Abad (Hormuzgan province) Using Macrobenthic Community Structure
This study aimed to investigate the population structure of benthic communities in Haji Abad River, West of Hormuzgan province. The study was conducted from October 91 till September 92. The three sites were determined based on regional topography and large benthic fauna. Sampling was performed monthly using a 500 micron Surber sampler with three replicates at each station. Samples were fixed i...
متن کاملIsolation, purification and identification of three diatom species (Bacillariophyceae) from Gomishan wetland (N. Iran) using phylogeny and silica cell wall ultra-structure analysis
Diatoms of Gomishan wetland (Golestan province, N. Iran), one of the most significant habitats in the eastern shore of the Caspian Sea, has been isolated, purified and identified during 2013. Using serial dilution and streaking on F/2 medium, pure, monoalgal and axenic cultures of the isolates were prepared. The isolates were characterized and identified using micro-morphological studies on the...
متن کاملDamage identification of structures using second-order approximation of Neumann series expansion
In this paper, a novel approach proposed for structural damage detection from limited number of sensors using extreme learning machine (ELM). As the number of sensors used to measure modal data is normally limited and usually are less than the number of DOFs in the finite element model, the model reduction approach should be used to match with incomplete measured mode shapes. The second-order a...
متن کاملکاهش ابعاد دادههای ابرطیفی به منظور افزایش جداییپذیری کلاسها و حفظ ساختار داده
Hyperspectral imaging with gathering hundreds spectral bands from the surface of the Earth allows us to separate materials with similar spectrum. Hyperspectral images can be used in many applications such as land chemical and physical parameter estimation, classification, target detection, unmixing, and so on. Among these applications, classification is especially interested. A hyperspectral im...
متن کاملOptimization of RFM's Structure Using a New Reformulation of PSO in Case of Limited GCPs
Metaheuristic algorithms have been widely used in determining the optimum rational polynomial coefficients (RPCs). By eliminating a number of unnecessary RPCs, these algorithms increase the accuracy of geometric correction of high-resolution satellite images. To this end, these algorithms use ordinary least squares and a number of ground control points (GCPs) to determine RPCs' values. Due to t...
