The goal of this work is to produce algorithm for coexistence in TVWS between 802.22 and 802.11 by equal opportunity without reduce in the delay time and throughput for each of them. Also, we investigate the coexistence problem between the 802.22 and the 802.11af systems in the TV White Spaces (TVWS). 802.22 And 802.11af are two typical standards e

The p-adic models of statistical mechanics require the investigation of the roots of polynomial equations over p-adic fields in order to construct p-adic Gibbs measures. The most frequently asked question is that whether a root of a polynomial equation belongs to the classic domains not. This question was open even for a quadratic equation. In this

Eco-friendly composites have been successfully prepared from the source of sugar palm tree. The effect of fibre contents on mechanical properties of sugar palm fibre reinforced plasticized sugar palm starch (SPF/SPS) biocomposites have been performed and the experimentally tensile properties (tensile strength and young’s modulus) of biocomposites

Optimization of basidiomycete mixed cultures for production of animal feed supplement in a solid state fermentation (SSF) remained elusive. Process conditions associated with improved protein enrichment of fruit peels by two white rot fungi were optimized using response surface methodology (RSM). Through one-factor-at-a-time (OFAT) method, six day

As image and video processing applications are leaning towards real-time requirement, the program control for the system must be designed efficiently while taking the processing time factor as one of the main considerations. This paper presents the method of detecting multicolour objects and the processing time comparisons of designed algorithms. A

Recently, incorporation of cement replacement material (CRM) in concrete has gained considerable attention throughout the world. It is known that the commonly used CRM in current concrete industry is silica fume (SF), pulverized fuel ash (PFA) and rice husk ash (RHA). RHA is an agricultural waste from rice milling process. Rice farming activities i

Based on some numerical calculations, S.M. Ulam has conjectured that the ergodic theorem holds true for any quadratic stochastic operator acting on the finite dimensional simplex. However, M.I. Zakharevich showed that Ulam's conjecture is false in general. Later, N.N. Ganikhodjaev and D.V. Zanin have generalized Zakharevich's example in the

It is known that polymeric materials are easily to get on fire due to their chemical structures. Thus the flame retardant material such as aluminium hydroxide (ATH) is used to improve the flame retardancy property of polymers. Polypropylene (PP) with various amount of nano-sized ATH particles of (5, 10, 20, 30, 40 wt%) were compounded with an extru

This paper investigates the average surface roughness (Ra) in micro-electrical discharge machining of electrically nonconductive zirconium oxide (ZrO2) ceramic using powder mixed dielectric. The gap voltage and concentration of tantalum carbide (TaC) powder are considered as the variable parameters for the investigation while other conditions are k

On the basis of some numerical calculations,Ulam has conjectured that the ergodic theorem holds for any quadratic stochastic operator acting on a finite-dimensional simplex. However, Zakharevich showed that Ulam’s conjecture is false in general. Later, Ganikhodzhaev and Zanin generalized Zakharevich’s example to the class of quadratic stochasti
