The gating system design for a die-casting die is a non-trivial task that involves a number of steps and computations, in which many factors related to part design, material, and process need to be accounted. In case of a multi-cavity die-casting die, the non-triviality of the gating system design increases manifold. The main contribution of this article is to develop a computer-aided system for design of gating system for multi-cavity die-casting dies. The proposed system applies design knowledge and rules, accounting for various influencing factors to design gating system elements and generate their computer-aided design models in an efficient manner. To demonstrate the capabilities of the developed system, the results for an industrial case study part are presented. We expect that the proposed system would help reduce manufacturing cost and lead time, alongside bridging gaps between design and manufacturing of the die-casting process. © 2015 Institution of Mechanical Engineers.

Die-design for the die-casting process is a time consuming and non-trivial task that requires domain knowledge and vast experience of a die-designer. Complexity of the die-design activity further increases in case of a multi-cavity die. In the present research work an attempt has been made to develop a computer-aided system, which facilitates design of a multi-cavity die-casting die taking part product model as input. The proposed system, multi-cavity die designer, works as an add-on application to an existing CAD software namely SolidWorks. To demonstrate capabilities of the developed system, the results for two industrial case study parts are presented. Proposed system is a step forward to design-manufacturing integration for die-casting process. Copyright © 2016 Inderscience Enterprises Ltd.

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.

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.

Use of industrial by-products as raw materials in concrete is becoming necessary to address the sustainability of both the concrete and the industrial growth. The present study assesses the potential of imperial smelting furnace (ISF) slag as in concrete, considering the presence of toxic elements (lead and zinc) and their detrimental effects on the early hydration of cement. Equivalent volume of sand was replaced by ISF slag in different percentages. Concrete specimens were prepared at different water-to-cement ratios. Compressive, flexural, and pull-offstrength, along with abrasion resistance, were examined. Leaching potentials of toxic lead, zinc, and cadmium from ISF slag concrete mixtures were also analyzed to evaluate environmental viability. Results are encouraging because sign of delay in setting was not observed. Improvement in compressive and pull-offstrength, comparable flexural strength and abrasion resistance, and leaching of toxic elements within safe limits assures the potential of future use of ISF slag as sand in concrete. © 2013 American Society of Civil Engineers.

This paper presents the use of genetic algorithms for optimizing the gains of a PID controller for a Servo DC Motor in contrast to the conventional methods of tuning. PID controller tuning with the help of the Genetic Algorithms comprises of obtaining the best possible outcome for the three PID parameters for improving the steady state characteristics and performance indices. This paper presents the parameter tuning of a PID controller to be used in driving a Servo DC Motor. For simulating the response of the Servo DC Motor modeling has been done in Simulink. The results obtained from the optimization using Genetic Algorithms are compared with the ones derived from the Ziegler-Nichols method. Comparatively better results are obtained in Genetic Algorithm case. © Research India Publications.

Diecasting is one of the forming methods which is used for producing large number of components with good surface finish by injecting cast alloys in a metal mould under high pressure. Design of a diecasting die requires human expertise and is normally performed by trial and error method, which leads to monetary and time loss. Automation at initial die design stage will result in higher productivity besides reducing production lead time. Decision about number of cavities, layout pattern and placement of cavities in diecasting is critical for die design and manufacturing. This paper presents research work related to system for computer aided cavity layout design for diecasting dies. Proposed system consists of three modules namely determination of number of cavities, selection of layout pattern and placement of cavities in the die-base. It enables die designers to generate cavity layout design automatically from CAD (Computer Aided Design) file of the part with little information provided manually. Optimal number of cavities is determined by considering economic, technical, geometrical and time limitations followed by selection of layout pattern. Thereafter, cavities are placed in the die-base. The developed system depends upon database of diecasting machines and materials along with a knowledgebase of die design. This system has been tried on a number of diecasting parts and results have been found to be on the lines of those obtained from industry. Proposed system is more comprehensive than those available presently and is a step forward in the direction of design-manufacturing integration for diecasting.

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.
