the main objective of this study is to investigate the production factors productivity in large manufacturing sub-sectors. for this purpose, using statistical data for period 1972-2004, we have tried to study and analyze the trend and level of production factors productivity (partial and total productivity) in each sub-sectors classified according to isic two digits code. the average and margin...

We describe the utility of integral representations for sums basic hypergeometric functions. In particular we use these to derive an infinite sequence transformations symmetrizations over certain variables which functions possess. These were studied by Bailey, Slater, Askey, Roy, Gasper and Rahman also used facilitate computation outstanding problems in theory orthogonal polynomials q-Askey sch...

<span>This article clarified the basic fiber Bragg grating (FBG) apodization functions effects on filtered optical acoustic signal (AS). Max power variations after acousto optic filter is with spectral wavelength variations. FBG are uniform, Gaussian, and Tanh. We have tested max various The AS amplitude electrical combiner reported based Apodization functions. studied lengths for at cent...

Domination theory is an important branch of Graph Theory and has many applications in Engineering, Communication Networks and many others. Allan, R.B., and Laskar, R., [1,2], Cockayne, E.J.,and Hedetniemi, S.T., [3], Haynes, T.W., and Slater, J.S., [4], have studied various domination parameters of graphs. Graphs associated with certain arithmetic functions which are usually called arithmetic g...
