In this paper, we present a binary-linear optimization model to prevent the spread of an infectious disease in a community. The model is based on the remotion of some connections in a contact network in order to separate infected nodes from the others. By using this model we nd an exact optimal solution and determine not only the minimum number of deleted links but also their exact positions. T...
Today, the global positioning systems (GPS) do not work well in buildings and in dense urban areas when there is no lines of sight between the user and their satellites. Hence, the local positioning system (LPS) has been considerably used in recent years. The main purpose of this research is to provide a four-layer artificial neural network based on nonlinear system solver (NLANN) for local pos...
In this paper, we analyze the effect of stress-fiber inclusion on the stiffness of an actin random network. To do this, use a discrete random network model to analyze the elastic response of this system in terms of apparent Young’s modulus. First, we showed that for a flat-ended cylindrical AFM indenter the total indentation force has a linear relation with the indentation depth and the indente...
Background and Aim: The utilization of technology acceptance model is one of the ways for perceiving the users' attitudes, and this research utilizes it to investigate the factors affecting the students' encouragement to use the social network sites in order to determine which factors encourage the students to use the social network sites as a virtual learning network. Methods: This research is...
the main purpose of this study was to investigate of economic impacts of soleimanshah dam on rural development in regions that are under influence of irrigation and drainage network of dam. in this research quantitative-qualitative research method was used and information gathered with questionnaire, interview, and direct observation. statistical population of research in qualitative part consi...
Iran’s geographical situation, in particular long-distance routes, makes rail transportation to be more attractive and important than the other modes. Since transport cost is the main concern for local and national authorities, Hub location is an important problem in transport planning in which transport industries are looking for selected points to change trains for passengers. In this pap...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
research topics dealing with the application of the markal model have been quite common in the last 20+ years. every new paper has added new insight into the potential of using such a model for a variety of purposes. not only global but also local applications have shown both limits and benefits when dealing with manifold energy-environmental-resources optimal management. the aim of this wo...
Abstract. We use the Local Optima Network model to study the structure of symmetric TSP fitness landscapes. The ‘big-valley’ hypothesis holds that for TSP and other combinatorial problems, local optima are not randomly distributed, instead they tend to be clustered around the global optimum. However, a recent study has observed that, for solutions close in evaluation to the global optimum, this...
forest management as one of the important source of production is crucial and critical. in taking over the forest resources as one of the most important of natural resources in the world, it is essential to consider local stakeholders to implement forest action plan for forest co-management. therefore, this study aims at achieving to proper management of forests based on evaluating the stakehol...
