The aim of this work is to design a mathematical model for deriving acoustic signatures by analyzing the sound of a ball mill in its load varying conditions. The paper establishes an appropriate mathematical background that helps to predict dynamic breakage characteristics with respect to particle size distribution of different types of material. Condenser based stereophonic microphones have been used for capturing the acoustic signal with different raw materials at different running conditions of the mill like with load, without load and saved in appropriate format for analysis. Using Kernel Density Estimator, a unique pattern for each state of the running mill is derived, i.e. Gaussian in nature. As a next step we apply Gaussian curve fitting for simulating the patterns based on the statistical parameters. Finally, a mathematical model has been established to follow the crushing operation of the grinding mill in predictive manner. The parameters are tuned in order to minimize the error between the experimental and the simulated results. The model has been validated in real time environment. © 2016 IEEE.

The paper introduces a very efficient and a new steganography technique, while keeping the quality of the cover image with strong security. Though the use of steganography is to hide secret messages in a cover object but the major drawbacks of existing methods are very less embedded payload and low security. To overcome this problem, perceptible degradation of stego-image is occurred. The proposed research work is based on the 24 bit color image steganography with secure hash function in spatial domain. In the present work the cover image has been decomposed into 2 by 2 non-overlapping blocks. Afterwards the first pixel component of each sub-block of RGB channel is used as the indicator. The two least significant bits of the first component specifies the order of secret bit(s) embedding into the rest three pixel components of the given sub-block. The hash values as obtained from six most significant bits decide the number of bits to be embedded in second, third and fourth components. Using this method the perceptible quality degradation has been minimized and hence data capacity has increased and security has also been enhanced. © 2016 IEEE.

In this paper, we propose a method to measure entropy and similarity for Intuitionist Multifuzzy Set (IMFS). Initially, we construct intuitionistic multifuzzy matrix from decision maker with respect to the objective criteria. Then, we construct aggregated intuitionistic multi fuzzy matrix using the Intuitionistic Multifuzzy Weighted Averaging (IMFWA) operator from intuitionistic multifuzzy matrix and decision maker weight. Decision maker weights are calculated by the proposed entropy base weight estimation method. Finally, similarity measurement method is applied to solve the problem on pattern reorganization, multi criteria decision making, medical diagnosis etc. © 2017 Taylor & Francis Group.

In this paper, we represent the threshold voltage modeling along with drain current, based on the surface potential of linearly graded binary metal alloy gate (Work Function Engineered Gate) Recessed Source / Drain (Re S/D) SOI/SON MOSFET with additional insulator region(IR -SOI). The proposed structure is similar to that of the Recessed S/D SOI MOSFET with the exception that there is an insulator region of high k dielectric in between the channel and drain region. Due to the presence of high k dielectric material the electric field is substantially reduced in the channel and drain regions. Therefore the proposed structure suppressed various short channel effects such as Hot Carrier Effect (HCE) which define the device degradation mechanism and hot electron reliability. The analytical surface potential model has been developed by solving two dimensional Poisson’s equation in the channel region considering appropriate boundary condition with parabolic potential profile. © 2017 Taylor & Francis Group.

The objective of this work is to validate the servo mechanism property of Repetitive Control (RC) system for periodic reference input in the presence of disturbance and in the presence of time varying parametric uncertainty. The ways of design and implementation of repetitive control system is demonstrated in steps. A similar test have been made having conventional PI-control and compared with RC based P control. Comparisons in terms of performances in both time and frequency (using bode plot) domain are done to show the effectiveness of the RC over the traditional idea. © 2014 IEEE.

Multi-Tasking digital microfluidic biochip raises some challenging issues in droplet routing in presence of on-chip defects. In this work, a heuristic droplet routing algorithm is proposed that tries to perform defect aware droplet transportation on digital microfluidic biochip. The aim of the proposed algorithm is to design defect-Avoiding and pin-count aware routing paths minimizing the following objective functions, (i) number or electrode usage during routing, (ii) routing completion time, and (iii) actuation pin count. The algorithm tries to find electrode fitness through a sum between, numbers of electrode elapsed in routing and an electrode count on rectilinear path between the candidate electrode and target electrode. A candidate electrode with minimum fitness value is selected for next movement in droplet route. During this routing control pins are simultaneously allocated through a comprehensive cooptimization method. This pin assignment technique helps in minimizing reuse of the resources for routing beyond sustainable level. Simulation results are compared with some exiting works and the improvement in this proposed work is quite encouraging. © 2016 ACM.

Commercial digital microfluidic biochip is facing an urge for design automation and test because of its complex multi-tasking paradigm. This work presents particle swarm optimization based technique for multiple fault detection in DMFB. The main objective of the algorithm is to localize the faults on a 2D biochip by circulation wash droplet, treated as the particle. PSO framework is modeled with the 2D biochip board as the search space for the particles. Multiple particles are generated from the reservoir and are circulated over the search space. Paths of the particles are guided by the velocity, which is decided upon previous knowledge of the particles' motion. The proposed work tries to find a time efficient procedure for fault localization with minimal number of particle encountered in the process. Simulation study shows that the process will enhance the reliability and accuracy in fault detection of the operational digital microfluidic biochips. © 2016 IEEE.

Servo control systems are very popular in process automation. Towards achieving and maintaining the desired speed in close-loop application, fuzzy controllers are more competent in comparison with their conventional counterparts. Based on the prior knowledge, a rule-base is designed here comprising of forty-nine if-then rules using simple triangular membership functions. The non-linear behaviour of such servo systems can also be efficiently managed by proper designing of rule-base with appropriate choice of scaling factors. Superiority of the designed fuzzy PI controller is verified through simulation study on a servo speed control system and in addition it is successfully implemented in real-time on a hardware setup. © 2015 IEEE.

A new approach for stability and reliability analysis of hybrid CMOS-SET circuits has been proposed. Using this approach, the stability of hybrid SET-CMOS NAND and NOR gates has been tested using SIMON. All the points corresponding to the control input vectors are found to be located in the stable white and grey portion of the stability plot. The influence of thermal fluctuations caused by increase in system temperature on the stability of the logic gates has also been thoroughly investigated. It was found that tunneling event increases with increase in temperature thereby decreasing the stability of the circuit. The reliability of the designed gates has been analyzed considering different variation factor of uniform and normal distribution of background charges. It was found that the reliability of the NAND gate is highly dependent on the value of the equivalent resistor and that it gave best result if the value of the resistor is kept in the middle of the range. NOR gate was found to be less affected by the value of the load resistor compared to the NAND gate. Copyright © 2014 American Scientific Publishers. All rights reserved.

HVAC systems control the temperature, humidity and air circulation in shopping malls. In these systems generally there is one main controlling unit as the Ventilation and Air-conditioning units are centralized. HVAC system consumes bulk amount of energy and idle consumption in a centralized system is always greater than the distributed system where each and every unit could be controlled separately. In present scenario, the HVAC systems installed in large shopping mall could not provide sufficient amount of oxygen and fresh air, and failed to maintain the desired temperature across the various zones where, crowd is more than the normal. For example a feeling of suffocation and more humidity are felt predominantly at the overcrowded locations like at the front of the payment counter or at the POS where large discount has been announced. In this paper the problem is identified and a suitable control system has been suggested to cater a better comfort and control over entire zone with reduced consumption of energy. In this proposed scheme the control system dynamically adjusts to the changing Building environment and load (number of Occupants and Sources of heat like lighting load, Electronic gadgets, Electronic Displays, computers, kitchen etc.). An automatic and effective Energy saving scheme has also been proposed without compromising with the comfort level of the occupants. © 2014 IEEE.
