introduction: telemedicine is defined as the ability to provide interactive health care by modern technologies and telecommunications which require related infrastructure and technologies. the aim of this study was to assess infrastructures of telemedicine at health centers, hospitals and clinics affiliated to shiraz university of medical sciences. method: this is a cross-sectional study conduc...

In this paper, a supply chain network design problem is explained which contains environmental concerns in arcs and nodes of network. It is assumed that there are some routes such as road, rail and etc. in each pair of nodes. In this model decision variables are choosing facilities to open, environmental investment level in each facility and flow of products between nodes in each route. A multi...

The facility layout problem has generally been formulated as a quadratic assignment problem, where the interacting facilities are assigned to the various sites. In this paper a different approach, based on assigning distances between pairs of sites to pairs of facilities, is taken. A network formulation and analysis of this problem is provided. An algorithm, composed of three phases, is develop...

During summer, melt ponds have a significant influence on Arctic sea-ice albedo. The melt pond fraction (MPF) also has the ability to forecast the Arctic sea-ice in a certain period. It is important to retrieve accurate melt pond fraction (MPF) from satellite data for Arctic research. This paper proposes a satellite MPF retrieval model based on the multi-layer neural network, named MPF-NN. Our ...

Governmental facilities for such services as education, health, and transportation are often small, of poor quality, and overcrowded, even when the costs are spread among all taxpayers. We also find that governments may subsidize private facilities providing the same services, or may charge admission fees at public facilities. We explain these phenomena with a model which considers two types of...
