In this paper, we aim at establishing certain integral transform and fractional integral formulas for the generalized Gauss hypergeometric functions, which was introduced and studied by özergin et al. [J. Comput. Appl. Math. 235(2011), 4601-4610]. All the results derived here are of general character and can yield a number of (known and new) results in the theory of integral transforms and fractional integrals. © 2014 NSP Natural Sciences Publishing Cor.

In this work have a problem of effects of fading. In problem formulation, it is assumed that the capacity gain and link reliability of MIMO (Multi Input Multi Output) systems was maximized that channels between pairs of transmit and receive antennas are independent of each other. The fading channel in wireless communications degrades the system Bit Error Rate (BER) performance significantly. MIMO channel, which employs multiple transmitters and/or multiple receivers, compensate the BER performance difference between fading channel and Additive White Gaussian Noise (AWGN) channel, because multiple replica of the information mitigates the randomness of fading channel. In this, the space diversity is studied and simulated. Space diversity includes two kinds of diversity: transmitter diversity and receiver diversity. Transmitter diversity means multiple transmitters are employed, which leads to Multiple Input Single Output (MISO) channel. Receiver diversity means multiple receivers are employed, which leads to Single Input Multiple Output (SIMO) channel. Employment of both multiple transmitters and receivers leads to Multiple Input Multiple Output (MIMO) channel. MIMO in conjunction with Space-Time Coding, which provides correlation on both temporal and spatial domain, is necessary for multiple transmitter system. We also describe a Space-Time architecture known as vertical BLAST (Bell Laboratories Layered Space-Time) or V-BLAST. The BER performance of these systems for different diversity are simulated and compared. © 2013 IEEE. Source

In this paper, we apply the concept of Caputo's H-differentiability, constructed based on the generalized Hukuhara difference, to solve the fuzzy fractional differential equation (FFDE) with uncertainty. This is in contrast to conventional solutions that either require a quantity of fractional derivatives of unknown solution at the initial point (Riemann-Liouville) or a solution with increasing length of their support (Hukuhara difference). Then, in order to solve the FFDE analytically, we introduce the fuzzy Laplace transform of the Caputo H-derivative. To the best of our knowledge, there is limited research devoted to the analytical methods to solve the FFDE under the fuzzy Caputo fractional differentiability. An analytical solution is presented to confirm the capability of the proposed method. © 2015 by the authors. Source

Several materials including fly ash, silica fume, metakaoline, wollastonite etc. which are either industrial wastes or naturally occurring minerals, have been investigated for making durable concrete material. Fly ash, silica fume, marble slurry etc. have been used in combination with wollastonite in cement concrete mixes for property enhancement. Huge amount of fly ash is being produced in India every year. It is expected to reach 225 million tons by 2017, creating its disposal problem which can be minimized by utilizing it in useful applications. The present investigation has been aimed to determine the influence of wollastonite-fly ash (W-FA) combination on properties of concrete such as strength, permeability, and durability over a range of water-binder (w/b) ratios and cement replacement. The microstructure and mercury intrusion porosity results of concrete mixes indicated that increased replacement levels of cement by W-FA combination (45-55%) causes some densification resulting into their enhanced mechanical and durability properties. © 2012 Elsevier Ltd.

Die-casting is one of the methods used to produce a large number of components with a good surface finish by injecting cast alloys into a metal mould under high pressure. The design of a die-casting die requires human expertise and is normally performed by trial and error, which leads to monetary and time losses. Automation at the initial die design stage would result in higher productivity and would reduce the production lead time. Decisions regarding the number of cavities, the layout pattern and the placement of cavities in die-casting are critical for die design and manufacturing. This paper presents research work on a system for computer-aided cavity layout design for die-casting dies. The proposed system consists of three modules: (1) determination of number of cavities; (2) selection of layout pattern; and (3) placement of cavities in the die base. It enables die designers to generate a cavity layout design automatically from a computer-aided design (CAD) file of the part with little information provided manually. The optimal number of cavities is determined by considering economic, technical, geometrical and time limitations, followed by the selection of a layout pattern. Thereafter, cavities are placed in the die base. The developed system depends on a database of die-casting machines and materials along with a knowledge base of die design. This system has been tested on a number of die-casting parts and results have been found to be along the lines of those obtained by the industry. The proposed system is more comprehensive than those presently available and is a step in the right direction for design-manufacturing integration for die-casting. © 2012 Taylor & Francis. Source
