Web services support the integration and interoperability of Web-based applications and enable machineto-machine interaction. The concepts of web services and open distributed architecture were applied to the development of T-DSS, the prototype customised for web based hydro-information systems. T-DSS provides mapping services, database related services and access to remote components, with spe...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
Visual saliency is a cognitive psychology concept that makes some stimuli of a scene stand out relative to their neighbors and attract our attention. Computing visual saliency is a topic of recent interest. Here, we propose a graph-based method for saliency detection, which contains three stages: pre-processing, initial saliency detection and final saliency detection. The initial saliency map i...
Problem Statement: In general, the drinking water systems sourced from ground water (GW) contains chemicals at double the current maximum contaminant levels (MCL) of colloids. However, due to increasing demand of water, groundwater may be subjected to over-exploitation and the natural equilibrium is thus disturbed. A steady-state condition is established between seawater and freshwater in a coa...

in this study with the inspirations from both neuroscience and computer science, a combinatorial framework for object recognition was proposed having benefited from the advantages of both biologically-inspired hmax_s architecture model for feature extraction and extreme learning machine (elm) as a classifier. hmax model is a feed-forward hierarchical structure resembling the ventral pathway in ...
امروزه یکی از دغدغههای مهم در بسیاری از کشورهای جهان، تأمین آب بهمنظور توسعۀ پایدار است. برای مدیریت مؤثر منابع آب زیرزمینی بهمنظور توسعۀ پایدار از یک سو به ابزار مناسب برای مدلسازی و از سوی دیگر به معیاری برای محاسبۀ پایداری نیاز است. این تحقیق وضعیت پایداری آبخوان با استفاده از مدل ترکیبی را که شامل مدل هیدرولوژیکی SWAT، مدل جریان آب زیرزمینی MODFLOW و مدل انتقال آلاینده MT3DMS میشود، ...
In systems and control theory dynamical systems described by partial differential equations are known as distributed parameter systems. For modelling and dynamical analysis of distributed parameter systems wide possibilities are offered by virtual software environments as ANSYS, COMSOL Multiphysics, ProCAST, MODFLOW, based on numerical solution of sets of partial differential equations by finit...
چکیده پیشروی آب شور در سفره های آب شیرین، تنها به جزایر و سواحل اقیانوس ها و دریاها و دریاچه های شور محدود نمی شود، بلکه امکان دارد سفره های آب شور، از طریق کویرها، باتلاق ها و چاله های آب شور در سفره های آب شیرین مجاور، پیشروی کنند و آن را شور و در شرایط بحرانی، غیر قابل استفاده سازند. ایران به دلیل داشتن آب و هوای خشک، دارای کویرهای فراون می باشد. محدودیت منابع آب های سطحی و بهره برداری بیش ...
