a side eeect, this search-intensity surface gives a clear indication of not just where has been searched but, more importantly, where has not yet been searched, providing for the rst time a measure of how thorough the ock search is. Conclusions The hybrid approach ooers many potential advantages over using any one of the methods independently. In a worst case scenario, the system should still p...

This paper presents a tuned behavior-based guidance algorithm for formation flight of quadrotors. The behavior-based approach provides the basis for the simultaneous realization of different behaviors such as leader following and obstacle avoidance for a group of agents; in our case they are quadcopters. In this paper optimization techniques are utilized to tune the parameters of a behavior-bas...

Background: 79% of the pregnant women suffer from sleep disorders and 70% of pregnant women have some of the depression symptoms. These disorders are the result of physiological changes, hormonal, physical, pregnancy which occur from different causes and can affect disorders before, during and after childbirth be involved in causing depression and may be aggravated by disregarding health behavi...

Hemangiopericytoma is a vascular tumor that is rarely seen in the nose and paranasal sinuses. Biological behavior of these tumors is not completely known, and their natural history is not predictable. This case report presents a patient with a sinonasal hemangiopericytoma. Diagnosis and management of these uncommon tumors is discussed.

The intention of this study is the analysis of thermal behavior of functionally graded beam (FGB). The distribution of material properties is imitated exponential function. For thermal loading the steady state of heat conduction with exponentially and hyperbolic variations through the thickness of FGB, is considered. With comparing of thermal behavior of both isotropic beam and FGB, it is appea...

Calcifying epithelial odontogenic tumor is a rare odontogenic neoplasm. Its occurrence in the maxillary sinus is very rare. Maxillary tumors tend to be locally aggressive and may rapidly involve the surrounding vital structures.  We report a case of calcifying epithelial odontogenic tumor involving maxillary sinus in a 48 years old female patient with the oral mucosal involvement. The purpose o...

rural sustainable development will be obtained through sound exploitation of environmental resources with an appropriate theoretical emphasis with protection and improvement of them for next generations. rural people behavior has important role in quality of these resources. this study was designed to develop a model of rural people environmental behavior. this study implemented in the west pro...
