In this research, we have proposed the central-symmetrical property of image reconstructions from Zernike moments and pseudo-Zernike moments. We conducted the image reconstructions from the odd, even, and complete sets of Zernike moments and pseudo-Zernike moments, and verified the proposed central-symmetrical property. We have concluded that if the original image is centrally symmetrical, the ...

Symmetrical peripheral digital gangrene is a life-changing complication, caused by a pro-thrombotic life-threatening disease, such as disseminated intravascular coagulopathy (DIC) secondary to systemic infection. We describe the unusual case of a woman who developed symmetrical peripheral digital gangrene following DIC because of malaria. While initial treatment led to cure of the infection, in...

In this paper a overcurrent protection using concept of symmetrical component for power transformer is presented .first we review the concept of symmetrical component. Secondly we investigate how the concept of symmetrical component can be used to improve the transformer protection scheme and how it helps to discriminate the fault and non fault events. For this an algorithm and discrimination c...

BACKGROUND AND PURPOSE A number of anatomicoclinical syndromes have been described in which bilateral symmetrical polymicrogyria is the underlying morphologic abnormality. We retrospectively reviewed the clinical, epileptic, and morphologic manifestations of bilateral symmetrical polymicrogyria in 21 patients to determine whether certain areas are at particular risk for these syndromes. METHO...

The occurrence of bilateral extradural hematomas (EDH) is an uncommon consequence of craniocerebral trauma, and acute symmetrical bilateral epidural hematomas are extremely rare. We discuss the technique adopted by us for the management of this rare entity. A 55-year-old patient presented with history of fall of branch of tree on her head. She had loss of consciousness since then and had multip...

There have been only single reports about the radiological changes in bones subsequent to frostbite in childhood and adolescence. We found only three cases on this subject in the literature. L6hr (1930) described a case in a 16-year-old boy; Bennett and Blount (1935) published the report of an 8-year-old girl, and Thelander (1950) of a 9-yearold boy. There are some thorough studies on this subj...

In this article we first present a mathematical model which describes the nonlinear dynamics of tensegrity structures. For certain tensegrity structures a particular class of motions, coined symmetrical motions, is defined. The corresponding equations of motion are derived and the conditions under which symmetrical motions occur are established. Reconfiguration procedures through symmetrical mo...
