Examination of smart grids in island operation
2009 IEEE Bucharest PowerTech, 2009This paper is qualified for the assessment of cooperation and interaction of smart grids (that means a micro network with about zero transfer power) and power system. Primarily it examines the effect of the continuously increasing integration of the intelligent energy distribution networks concerning the stability of the power system.

Rotated Island Graft Operation for Pterygium
American Journal of Ophthalmology, 1926This operation isolates the bulk of the pterygium by four incisions. Sutures are introduced in such a way as when tightened to rotate the isolated square 90 degrees. It is fixed in position with the help of additional sutures if needed. The operation is applicable only to exceptionally severe cases, which may have not been corrected by other operations.

On-line Islanding Operation Based on CSP
2010 Asia-Pacific Power and Energy Engineering Conference, 2010In event of fault in distribution system with distributed generators, in order to enhance service reliability, the DGs should be used as main power source for blackout area. Deeply considering the characteristic in the service restoration process and the type of switches, the model based on CSP is proposed to solve the on-line islanding operation ...

Bathurst Island Group and Byam Martin Island, Arctic Canada (operation Bathurst Island)
1972The Bathurst Island group, and Byam Martin Island, together occupy about 8,000 square miles of land area. They are situated near the geographic center of the Canadian Arctic Archipelago and encompass the north magnetic pole. Most of the area is covered by sedimentary rocks of Ordovician to Late Devonian age, with a composite exposed thickness of ...

scientific co‐operation in the Aleutian Islands
Eos, Transactions American Geophysical Union, 1926The topic for the symposium was suggested by the immediate prospect of the founding of a volcano observatory in the Aleutian Range under the United States Geological Survey. The Aleutians are difficult of access and remain but little more explored than when Alaska was first acquired.

Research Operations on Jan Mayen Island
2004The remoteness of Jan Mayen Island makes it rather inaccessible for scientists and the ruling arctic conditions require logistics that secure conditions for field research. The scope of research interests ranges from Global climate and hemispheric meteorology, seabed tectonics and volcanology, and geophysics of the World Ocean and the proximal Nordic ...

Trackless Trolley Operation In Rhode Island
Transactions of the American Institute of Electrical Engineers, 1949This paper attempts to set forth the knowledge gained in operating a growing trackless trolley system over a period of 17 years. It in no way is intended to prove that the trolley coach is a cure-all for transit ills. Unbiased transit experts recognize the need for all types of vehicles in the industry: ``A place for every vehicle-every vehicle in its ...
