Previous methods on improving translation quality by employing multiple SMT models usually carry out as a secondpass decision procedure on hypotheses from multiple systems using extra features instead of using features in existing models in more depth. In this paper, we propose translation model generalization (TMG), an approach that updates probability feature values for the translation model ...

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...

In this study, we first analyze the specific dynamics of the shelter site location problem for an application in Turkey and develop a mixed integer linear programming based methodology which incorporates with their requirements of the Turkish Red Cresent and improve their current system. The mathematical model maximizes the minimum weight of open shelter areas while deciding on the location of ...

In the present economic context, the operating theater is considered as a critical activity in health care management. This paper describes a model for operating room (OR) planning under constraint of a unique equipment. At first level we schedule elective surgeries under the uncertainty of using a unique equipment. At the second level we consider emergency surgeries, and at the third le...

Limitations on water resources and the high costs of new hydraulic structure construction intensify the need for an optimum operation of Iranian reservoir systems. For appropriate water distribution and management in a 9-reservoir system on the Kalamarz river, Mianeh basin optimizing mathematical models are applied. Considering the stochastic nature of river discharges and the constant amount o...

Stochastic channel error models are an important part of performance evaluations of wireless protocols. In fact, for a given protocol often the performance measures of interest seen in simulations depend on the choice of the error models, often simpler models give poorer quality performance predictions. This paper presents a new class of Markovianbased channel models, called bipartite models. T...

substitution management planning, as one of the important issues in manpower planning, is referred to as a process of filling the gaps and fulfilling the needs of very crutial and key elements of organization in managerial levels. meeting the needs by means of using external and internal manpower of the organization seems to be rational. however, it has some advantages and disadvantages. this p...
