In this paper, ant colony optimization (ACO) algorithms are proposed for reservoir operation. Through a collection of cooperative agents called ants, the near-optimum solution to the reservoir operation can be effectively achieved. To apply ACO algorithms, the problem is approached by considering a finite horizon with a time series of inflow, classifying the reservoir volume to several interval...

Echo state networks (ESNs) with multi-clustered reservoir topology perform better in reservoir computing and robustness than those with random reservoir topology. However, these ESNs have a complex reservoir topology, which leads to difficulties in reservoir generation. This study focuses on the reservoir generation problem when ESN is used in environments with sufficient priori data available....

The investigation and exploration of potential deep geothermal systems is based on detailed knowledge of their distinct reservoir characteristics. This is especially important in the exploration of potentially engineered geothermal systems and of mid to low enthalpy reservoir formations in greater depths, resp. In the early stages of geothermal reservoir exploration, characterization of the res...

background: hydatidosis is a zoonotic disease of global prevalence. it causes considerable health problems and economic losses throughout the world, including iran. the objective of this study was to assess the current status of echinococco-sis/hydatidosis in the province of ilam (western iran). methods: from april to september 2011, 65 stray dogs were collected from urban and rural areas of il...

The north of Ilam Province in Iran has a great variety geodiversity features, and the presence resources, along with other geological geomorphological values, enriched area. purpose present study is to evaluate Province. main indices for assessing include geology, geomorphology, geomorphosites, paleontology, pedology, hydrology, mineral fossil species. In addition geodiversity, hazard maps area...

Building upon the foundation of the prior investigations, a three-fold classification of tight gas reservoirs is proposed in this paper which is based primarily on dynamic relationship between gas charging history and reservoir tightening process, coupled with tectonic evolution, source-reservoir relationship, migration and charging pattern. The three categories of tight gas are: (1) “pre-exist...
