The application of conventional wind turbines on board a vessel creates a number of new challenges for turbine control systems. Thrust force is used in marine applications as an additional control variable for propulsion of the vessel. Variability of the wind speed and wind direction, together with the yaw rate and range constraints, impose strong requirements on the turbine control system. A n...

The past inflexibility of international banks in granting concessions (like elimination of surcharges, partial debt cancellations, lower interest rates, etc.) is linked by Ortiz to case-by-case strategy adopted in debt renegotiations. Within this context, the fear of setting precedents is seen as a major explanation in the banks' negotiating stance. To renew political commitment to the improvem...

Data from interviews conducted with residents of a homeless shelter supported the hypothesis that perceived loss of control over the shelter environment would be positively related to giving up on finding a home and emplo...

Within the context of tele-presence and immersion for piloting light aircraft, knowledge about the surrounding wind offers useful information for piloting purposes. Rendering wind in virtual simulation or telepresence application has been used still the early sixties [1] to enhance immersion. However since then it has been rather limited to use a fan in front of the user to produce an illusion ...

Most cities around the world are in danger of disasters. Among disasters, the earthquake is the most dangerous and ruining one. Iran has been located in the Alpine-Himalayas seismic belt, and because of the significant frequency of severe earthquakes happening all over the country compare to other countries and the state of the unsecured residential and non-residential buildings in most of the ...

The purpose of the work is to investigate a monitoring of autonomous photovoltaic battery wind turbine hybrid system (PVBWHS). The PV array, wind turbine and the storage batteries sizes are estimated based the site of application; Jazan province, KSA. The sizing result of the proposed PVBWHS is generator with 2.16kW, wind turbine generator with 2kW, Battery Bank with ~400Ah, and 5kW ratings of ...

This study examined the rate of admission to public shelters between 1990 and 1992 among persons who received Medicaid-reimbursed inpatient and outpatient psychiatric services and inpatient substance abuse services in Philadelphia between 1985 and 1993. Results show that 7.5 percent of such persons were admitted to public shelters during the three-year period, nearly 2.7 times the rate of shelt...

The importance of a house in enabling individuals and families to attain physical shelter from inclement weather, provide security, a ‘grounded’ attachment to place, and enhance the quality of life of residents is an idea that has universal acceptance. Particularly since the Second World War, it has become an integral part of the popular imagination. The almost iconic status of what a house rep...
