Face recognition system have been widely developed. The machine vision system becomes an interest of many researchers in various fields of science. It provides the most important characteristic of natural interaction that is personalization. Automatic face recognition is a challenging problem, since human faces have a complex pattern. This paper presents a method for recognition of frontal huma...

Background: In patients with ST-segment elevation myocardial infarction (STEMI), Primary percutaneous coronary intervention (PCI) is the preferred reperfusion therapy. Timely primary PCI is essential in improving the clinical outcomes of these patients. The aim of this study was to evaluate the factors affecting balloon delay in STEMI treated patients by primary PCI and its relationship with ma...

This paper studies whether trading in social networks allocates a new technology efficiently. I use a field experiment in Odisha India to compare decentralized trade of a new technology through networks with an approach where demand was revealed via door-to-door sales. While 84% of farmers are expected to gain from the technology, only 7% adopt in networks. Conversely, 40% of farmers adopt when...

Indoor navigation is gaining an increasing interest among researchers in many domains. In many cases users need to orient quickly in complex environments, which is not always the target of current routing algorithms. The paper reviews current indoor pathfinding approaches and discusses some of the limitations. In order to support a natural movement in buildings, typically for emergencies, we pu...

For over the past several decades, there has been a great concern about energy crisis and lackof non-renewable resources. Residential buildings take more than 25% of the total energy consumption and morethan 75% of energy consumption in these buildings is for heating, cooling and hot sanitary water. On the other hand,traditional buildings of Iran were designed according to ecological conditions...
