background some grafts harvested from the groin area do not become hyperpigmented and in an individual with multiple pieces of grafts, the hyperpigmentation of the pieces may vary. this study evaluates the orientation of the inset of groin grafts according to their donor sites (superior-inferior) and its role in graft hyperpigmentation. methods patients with hand burn contracture or syndactyly ...

ntroduction. Operation of adaptive system moving targets selection is considered, which represented by single intermittent subtractor with coherent accumulator, tuned in frequency. System made the form two quadrature channels, high-frequency passive interference and signal from object are converted to video frequency subsequent rejection, accumulation comparison threshold level. Setting task. I...

<p><span>The reversible logic gates are used to improve the power dissipation in modern computer applications. The floating-point numbers with features added advantage performing complex algorithms high-performance computations. This manuscript implements an efficient arithmetic (RFPA) unit, and its performance metrics realized detail. RFP adder/subtractor (A/S), multiplier, divider...

Emerging trends in proof styles and new applications of interactive proof assistants exploit the computational facilities of the provided proof language, reaping enormous benefits in proof size and convenience to the user. However, the resulting proof objects really put the proof assistant to the test in terms of computational time required to check them. We present a novel translation of the t...

Low power dissipation, high packaging density and operation at Tera-hertz frequencies are highly desired features in the design and fabrication of logic circuits. Promising realization of these highly desired features have made Quantum dot Cellular Automata (QCA) a prospective replacement to the conventional CMOS technology for the fabrication of logic circuits in nano scale range. The traditio...

In this paper we study the following simple and mind-puzzling problem: Can a model train car, which runs along an intricate track complete a full cycle around it? In our paper a track will be represented by a simple closed curve, and the cars of our model train by segments whose end-points lie on the curve.
