The major objective of image segmentation is to extract objects with respect to some input features. One of the impotent methods for image segmentation is Level Set method. In conventional level set function the LSF develops irregularity during its process of evaluation of contour of objects, this destroy the stability and smooth flow of evolution process. A method of selective region-based active contour model (ACM) is suggested in this work, in this first selectively penalizes the level set function to be binary, then uses a Gaussian smoothing kernel to regularize couture evolution. A new region-based signed pressure force (SPF) function is proposed, which can efficiently stop the contours at weak or blurred edges. Other feature is the exterior and interior boundaries can be automatically detected with the initial contour being anywhere in the image. The proposed ACM, it has the property of selective local or global segmentation. The level set function can be easily initialized with a binary function, which is more efficient to construct than the widely used signed distance function (SDF). © 2016 IEEE.

Scheduling of flexible manufacturing systems is a well-known NP-hard problem which is very complex, due to additional considerations like material handling, alternative routing, and alternative machines. Improvement in the performance of a flexible manufacturing system can be expected by efficient utilization of its resources, by proper integration and synchronization of their scheduling. Differential evolution is a powerful tool which proved itself as a better alternative for solving optimization problems like scheduling. In this paper, the authors addressed simultaneous scheduling of both machines and material handling system with alternative machines for the makespan minimization objective. The authors proposed a machine selection heuristic and a vehicle assignment heuristic which are incorporated in the differential evolution approach to assign the tasks, to appropriate machine and vehicle, and to minimize cycle time.

The effect of grain refining elements such as copper, titanium and aluminum on transverse tensile strength, ductility, impact toughness, microhardness and austenite content of AISI 430 ferritic stainless steel welds through Gas Tungsten Arc Welding (GTAW) process in as-welded condition was studied. Taguchi method was used to optimize the weight percentage of copper, titanium and aluminum for maximizing the mechanical properties and austenite content in the weld region of ferritic stainless steel welds. Based on Taguchi orthogonal array the regression equations were developed for predicting the mechanical properties of ferritic stainless steel welds within the range of grain refining elements. The observed mechanical properties and austenite content have been correlated with microstructure and fracture features. © 2011 Elsevier Ltd.

Transmission of energy efficiently is a major goal of Wireless Sensor Network for its lifetime. Wireless sensor network consumes more power, as nodes perform on restricted power batteries which decrease its lifetime, a vast field for researchers to work in several fields like industrial automation, environmental monitoring and military applications. Implementation of error control scheme for reduce of bit error rate (BER) is essential In this work, we aim to evaluate the performance analysis of BPSK and QPSK modulation with different strategies using different analysis parameters such as Bit Error Rate (BER), energy used. The ratio of BER and SNR is analyzed in this paper. This paper may be used and modified further for better analysis of different modulation schemes to improve the lifetime of the clustered sensor network. © 2016 IEEE.

Large quantities of industrial wastes are being generated worldwide due to rapid urbanization and industrialization. In India, aggregate crusher units produce enormous quantities of stone dust, a by-product produced during crushing of stone. Stacking or disposal of such large quantities of stone dust in open areas is not an environment friendly solution. Utilization of this by product in civil engineering applications is likely to provide an acceptable solution. Efforts are underway to utilize stone dust in civil engineering construction industries so that minimizing the threat caused to environment in the direction of sustainable development. In this direction, present paper pertain the results of the compressive strength experimental study carried out on material prepared using stone dust and expanded polystyrene(EPS) beads. The experiments were conducted by adding EPS beads with different mix proportions with respect to the weight of stone dust. The mix ratio percentages used in the present study are 0.033, 0.066, 0.099, 0.132, and 0.165. Density of EPS beads used in the study is 16 kg/m3. Cubical specimen of size 70 mm × 70 mm × 70 mm was used for evaluating the compressive strength of material for curing periods of 7 and 14 days. The results indicate that the compressive strength, density and stress-stress pattern of the prepared material was significantly influenced by the curing period and mix ratios. For a particular mix ratio value, compressive strength of material increased with increasing curing period and for a particular curing period value it decreased with increasing mix ratios. The density of the material is decreased with increasing mix ratio values. The relationship between stress and strain was observed to be nonlinear. © ASCE.

Software reuse is one of the major research area in component based software engineering (CBSE). It is an area which integrates all the other technical areas like data mining, soft computing, artificial intelligence etc. The major areas which are to be focused in software reuse are classification, clustering, searching, indexing and retrieval of software components. There are many techniques described in literature each with their advantages and limitations. In this paper, we propose a dynamic approach where the components are retrieved by using genetic algorithm. The proposed algorithm mainly focuses on the termination condition or stopping criteria of Genetic Algorithm, which changes dynamically based on the user query. Genetic Algorithm (GA) stops the evolution i.e., reaches convergence when the average fitness value of the population becomes equal to the fitness value of the user query. © 2015 IEEE.

An ultra-wide band (UWB) monopole antenna with a band-notch characteristic is presented which needs only two parameters to tune the notch frequency. The proposed monopole antenna is embedded with loading strip, whose length is determined by parametric study. By adjusting the loading strip length and width, the notched frequency bandwidth the antenna's operating bandwidth can be easily controlled. The time-domain behaviors are discussed. The antenna is suitable for operating frequency of 7.5 GHz. It is shown that return loss of the antenna at 7.5 GHz is better than -10 dB. The VSWR obtained is less than 2. Details of the proposed antenna design and measured results are discussed. © 2015 IEEE.

As Moors law is concerned, down scaling of conventional CMOS technology results in, rapidly approaching fundamental limits. Alternative device structures are constantly proposed to substitute the traditional CMOS type devices. That type of device is a gated reverse-biased structure, commonly referred to as Tunnel Field-Effect Transistor (TFET). This device is particularly suitable for ultra-low-power applications. The most prominent feature of TFETs is their capacity for producing an inverse sub-threshold swing (SS) smaller than the 60 mV/decade thermal limit (at 300 K) of conventional inversion mode MOSFETs. Sub-thermal SS is achievable because, the drain current in TFETs is produced by carrier injection from source to channel which is predominantly governed by quantum mechanical band-to-band tunnelling (BTBT), rather than by diffusion as in MOSFETs. In, this paper we will show the silvaco TCAD simulation results for both conventional MOSFET and Tunnel field effect transistor. From the results, it is evident that TFET is suitable for ultra-low power applications. © 2016 IEEE.

In India, enormous quantity of stone dust is produced from the crushing of stone at quarry sites. In the direction of sustainable development, it is desirable to use stone dust to the maximum extent in the construction activities. A series of compressive strength tests have been performed on newly developed construction material (NDCM) prepared using stone dust, expanded polystyrene (EPS) beads and binder material such as cement. Two different densities of EPS beads 22 kg/m and 16 kg/m were used in the study. The mix ratio percentages used in the study are 0.25, 0.75, and 1.25. The compressive strength of material was evaluated for curing periods of 7, 14, and 28 days. For a particular mix ratio value, compressive strength of material increased with increasing curing period and for a particular curing period value it decreased with increasing mix ratios. The density of NDCM was found to be decreased with increasing mix ratios for both the densities EPS beads. For a particular mix ratio, NDCM prepared using EPS beads of density 16 kg/m shows lower density that that of prepared using density 22 kg/m. For a particular mix ratio and for each curing days, NDCM prepared using EPS beads of density 22 kg/m shows higher compressive strength than EPS beads of density 16 kg/m.

Bottom ash is a by-product produced from burning of pulverized coal in thermal power plants. The increasing production of bottom ash and its disposal in an eco-friendly manner is a matter of concern. This paper concisely describes the suitability of bottom ash to be used in civil engineering applications as a way to minimize the amount of its disposal in the environment and in the direction of sustainable development. The proposed geomaterial was prepared by blending bottom ash with expanded polystyrene (EPS) beads and a binder such as cement. The experiments were conducted by adding EPS beads with different mix proportions. The mix ratio percentages 0.3, 0.6, 0.9, 1.2, and 1.5 were used in the study. The cement to bottom ash (C/BA) ratios of 10 and 20% were used in the study. All the ratios used in the study are with respect to weight of bottom ash. The compressive strength of geomaterial was evaluated for curing periods of 7, 14, and 28 days. The effects of various mix ratios, cement content, and curing periods on the density, compressive strength, and initial tangent modulus was studied and the results were incorporated. Test result indicated that the density of geomaterial reduced from 650 to 360 kg/m3 with addition of EPS beads from 0.3 to 1.5%. For a particular curing period, compressive strength reduced marginally following the inclusion of EPS beads in geomaterial. For each mix ratio, compressive strength increased with increasing curing periods. The initial tangent modulus of the geomaterial decreased with increasing mix ratio values. The prepared geomaterial was light in weight comparitively and it can be used as a substitute to conventional fill materials. © 2015 American Society of Civil Engineers.
