Research in wireless physical and link layers is restricted in many cases by the transceiver chip hardware, with its specic limitations, the software drivers for the hardware, which are sometimes only available in binary format and not modiable. Software Dened Radios oer the possibility to do research in those layers without the showstoppers of the chip and/or the driver. TinyOS has given the a...

Genomi aberrations are often seen in the analysis of solid tumors. Aberrations on a band level an be found by oloring the bands of the hromosomes with various dyes. When looking at the hromosomes in a mi ros ope, a trained eye an identify missing or inserted regions. Early aberrations are believed to afe t the probability of other aberrations to o ur. This model views the an er progression as a...

(1992). 12 approach should be combined with precise designing tools. Adding the ability to merge curves using Boolean operations will allow one to merge a circle with the tip of the wing, making it feasible to precisely design the cross-section of the missile. The techniques presented herein with the aid of the NUBS representation can be easily enhanced to support these features. The method pre...

1 This thesis develops a new approach to the formal denition of a truth predicate that allows a consistent, semantically closed denition within classical logic. The approach is built on an analysis of structural properties of languages that make Liar Sentences and the paradoxical argument possible. By focusing on these conditions, standard formal denitions of semantics are shown to impose syste...

BACKGROUND Conventional anterior cervical discectomy with fusion is thought to require postoperative neck immobilization for the promotion of bony fusion. Rigid internal fixation with anterior cervical plates may decrease graft-related complications and provide immediate stability. This stability may obviate postoperative external immobilization. METHODS This report reviews one surgeon's expe...

In this paper, we introduce a new class of implicit functions and also common property (E.A) in modified intuitionistic fuzzy metric spaces and utilize the same to prove some common fixed point theorems in modified intuitionistic fuzzy metric spaces besides discussing related results and illustrative examples. We are not aware of any paper dealing with such implicit functions in modified intuit...

This paper discusses the issues in estimating the effects of marketing variables with linear models. When the variables are not directly observable, it is well known that direct regression yields biased estimates. Several researchers have recently suggested reverse regression as an alternative procedure. However, it is shown that the reverse regression approach also fails to provide unbiased es...

Applying the rules of translation is even simpler. In essence, all that is needed is a mechanism for arranging There are various difficulties in accomodating the traditional logical expressions into larger expressions in conformity with mass/count distinction into a grammar for English which the semantic rules. (For examples of parsers see Thompson has a goal the production of "logical form" se...

The Langley 8-Foot High-Temperature Tunnel (8-ft HTT) is used to test components of hypersonic vehicles for aerothermal loads de nition and structural component veri cation. The test medium of the 8-ft HTT is obtained by burning a mixture of methane-air under high pressure; the combustion products are expanded through an axisymmetric conical-contoured nozzle to simulate atmospheric ight at Mach...
