In arid and semi-arid environments, groundwater plays a significant role in the ecosystem. In the last decades, groundwater levels have decreased due to the increasing demand for water, weak irrigation management and soil damage. For the effective management of groundwater, it is important to model and predict fluctuations in groundwater levels. In this study, groundwater table in Kashan plain ...

Environmental impact assessment (EIA) has led to the dominance of planners on the natural environment of the regions, providing the possibility of continuously monitoring and controlling the status quo by management staff. In this regard, a new semi-quantitative model is presented for the EIA of the Eastern Alborz Coal Mining complex using the matrix method, and determining the corresponding im...

purpose ankle sprain is one of the most common injuries among athletes and instability and injury to this joint is responsible for long time loss of physical and recreational activity. also, it can impose high costs to sport teams. prevention of this injury is an important concern of practice and rehabilitation. one way of reducing the possibility of ankle joint injury is using an ankle orthosi...

This article presents a virtual prototyping study of a semi-active lower limb prosthesis to improve the functionality of an amputee during prosthesis-environment interaction for level ground walking. Articulated ankle-foot prosthesis and a single-axis semi-active prosthetic knee with active and passive operating modes were considered. Data for level ground walking were collected using a photogr...

This paper has proposed a Graph – semantic based conceptual model for semi-structured database system, called GOOSSDM, to conceptualize the different facets of such system in object oriented paradigm. The model defines a set of graph based formal constructs, variety of relationship types with participation constraints and rich set of graphical notations to specify the conceptual level design of...

We introduce a novel approach for detection of objects from aerial images at the level of pixels using semi-supervised learning. Buildings in aerial images are complex 3D objects which are represented by features of different modalities include visual information and 3D height data. Semi-supervised learning is a classification which additional unlabeled data can be used to improve accuracy. Thi...

We introduce a new numerical solution method for semi-infinite optimization problems with convex lower level problems. The method is based on a reformulation of the semi-infinite problem as a Stackelberg game and the use of regularized nonlinear complementarity problem functions. This approach leads to central path conditions for the lower level problems, where for a given path parameter a smoo...
