The analog of Toupin's version of Saint-Venant's principle is proved for an isotropie, linear elastic mieropolar body of arbitrary length and of uniform cross-section which in the unstressed state is helical. That is, when such a body is loaded by self-equilibrated stresses and couple stresses at one end only, we show that the elastic strain energy stored in the part of the body beyond a certai...

language like other inventions was originated to serve human needs in different civilization. different language was created later. contextually the importance of translation from one language to another is not only to understand words; as the words are not the elements of translation. importance and base of translation lies in context to understand it. after getting the content, one should d...

ENIAC WAS BUILT during the Second World War, from 1943 to 1945. Many consider it the rst electronic, general-purpose, large-scale digital computer. Picture it as a room encompassing 36 racks, three printer panels, a card reader, and a card punch. Each rack used hundreds of vacuum tubes to perform a speci c function. Many racks acted as accumulators: they received pulses corresponding to the dig...

A Room Impulse Response (RIR) shows a complex time-frequency structure, due to the presence of sound re ections and room resonances at low frequencies. Many acoustic signal enhancement applications, such as acoustic feedback cancellation, dereverberation and room equalization, require simple yet accurate models to represent a RIR. Parametric modeling of room acoustics attempts at approximating ...

In recent years space-division multiple access (SDMA) has been suggested in order to increase the capacity of a cellular mobile communication system and to simultaneously combat the losses due to multipath and interference. This is achieved by using spatial diversity introduced by an antenna array and therefore SDMA can easily be implemented as an additional component into existing systems that...

Statistics-based colour constancy algorithms work well as long as there are many colours in a scene, they fail however when the encountering scenes comprise few surfaces. In contrast, physics-based algorithms, based on an understanding of physical processes such as highlights and interre ections, are theoretically able to solve for colour constancy even when there are as few as two surfaces in ...

we reported a 35 year old breast cancer patient who was referred to our nuclear medicine department for sentinel node mapping. she was planned to undergo mastectomy and lymphatic mapping. a dose of tc-99m phytate was injection in the peri-areolar region in an intra-dermal fashion. two hours post-injection no sentinel node was visible in the axilla. due to a high liver uptake, inadvertent intra-...

objectives: this study aimed to assess the effect of re-etching of desensitized dentin for five and 10 seconds on marginal microleakage of composite restorations. materials and methods: class v cavities (4x2x2mm) were prepared on the buccal surfaces of 64 third molars and randomly divided into four groups of 16. in the control group, single bond (sb) adhesive was applied after etching. in bb+sb...
