An accurate and standardized technique for breast tumor segmentation is a critical step for monitoring and quantifying breast cancer. The fully automated tumor segmentation in mammograms presents many challenges related to characteristics of an image. In this paper, a comparison of two different semi-automated methods, viz., level set and marker controlled watershed methods that perform an accurate and fast segmentation of tumor is made. The robustness of the proposed methods is demonstrated by the segmentation of a set of 17 mammogram images. Numerical validation of the results is also provided. © 2009 Elsevier Ltd.

Wireless Sensor Networks offer several applications but limit in their energy resource. Efficiency and lifetime of these networks depend on the proper use of their energy. Energy in these networks can be efficiently consumed using mechanism of clustering. Any clustering mechanism depends upon the criteria used in the cluster head selection. In order to select a Cluster Head, this paper presents a mechanism HEEC-RND that takes into account three factors - the node's residual energy, node degree and node's distance from the base station. Compared with other techniques, the technique increases the network lifetime and decreases the network energy decay. © 2015 IEEE.

The PMSM motors are increasingly playing an important role in modern motor drives. A shaft encoder or sensor connected to the shaft of the motor provides feedback required for controlling torque and speed to the PMSM. So many motor drives are not abiding by the application of this feedback device because of their reliability concerns, price, and space and weight limitations. This paper analysis the adjustable current model in which PMSM itself acts as reference model, with the parameter of speed revolution adjustable for the sensor less speed control of PMSM, a model reference adaptive system mechanism is used. The control scheme is simulated in the Matlab/Simulink software environment. The simulation result shows that the speed of rotor is estimated with high precision and response is considerable fast. It also shows that the whole control system is effective, feasible and simple. © 2013 IEEE.

Rationale and Objectives: This article provides a survey of segmentation methods for medical images. Usually, classification of segmentation methods is done based on the approaches adopted and the domain of application. Materials and Methods: This survey is conducted on the recent segmentation methods used in biomedical image processing and explores the methods useful for better segmentation. A critical appraisal of the current status of semiautomated and automated methods is made for the segmentation of anatomical medical images emphasizing the advantages and disadvantages. Computer-aided diagnosis (CAD) used by radiologists as a second opinion has become one of the major research areas in medical imaging and diagnostic radiology. A picture archiving communication system (PACS) is an integrated workflow system for managing images and related data that is designed to streamline operations throughout the whole patient care delivery process. Results: By using PACS, the medical image interpretation may be changed from conventional hard-copy images to soft-copy studies viewed on the systems workstations. Conclusion: The automatic segmentations assist the doctors in making quick diagnosis. The CAD need not be comparable to that of physicians, but is surely complementary. © 2010 AUR.

Digital images are the most common cover files used for steganography. In this paper, a new steganography method called JMQT based on modified quantization table is proposed. This steganography method is compared with steganography method JPEG-JSteg. Two performance parameters namely capacity and stego size has been compared. As a result capacity increases and stego size increases. So JMQT provides better capacity and JPEG-JSteg provides better stego-size. © 2012 IEEE.

Undoped and Erbium (Er) doped zinc oxide (EZO) thin films were deposited on glass substrate by sol-gel method using spin coating technique with different doping concentration. EZO films were characterized using X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), UV-VIS-NIR transmission and single beam z scan method under illumination of frequency doubled Nd:YAG laser. The deposited films were found to be well crystallized with hexagonal wurtzite structure having a preferential growth orientation along the ZnO (002) plane. A blue-shift was observed in the band gap of EZO films with increasing Er concentration. All the films exhibited a negative value of nonlinear refractive index (n 2) at 532 nm which is attributed to the two photon absorption and weak free carrier absorption. Third order nonlinear optical susceptibility, χ (3) values of EZO films were observed in the remarkable range of 10 - 6 esu. EZO (0.4 at.%) sample was found to be the best optical limiter with limiting threshold of 1.95 KJ/cm 2. © 2012 Elsevier B.V. All rights reserved.

Speech for realistic environment is hard to achieve. Emotion synthesizing is one way to achieve realistic and natural sounding speech. Use of right emotion in synthesized speech generates the speech which is more effective and natural for listener. The implementation of emotions is very difficult, as word "emotion" has no single definition. There have been various attempts in creating emotional speech synthesis but perfect or near to ideal system has not been developed so far. Our paper is an attempt to create emotional speech synthesizer, where we have used the emotional database recorded in our own voice. We have used unit selection and CART method to implement it. We have taken class room environment for teaching pre-school students with three emotions i.e neutral, happy, sad and tested our synthesizer with twenty listeners and found that listeners have significantly identify the emotional state of speaker. © 2013 Springer International Publishing.

The redundancy in English words helps the unauthorized entity to guess the cipher text. The DNA sequences do not follow such properties. It means the conversion of message to DNA sequences make it robust against attacks. This paper performs the DNA cryptography and then hides the DNA sequence in to the random frame of a video. The result analysis shows that the frame is imperceptible. The video seems to be same. The enhancement in PSNR value and reduction in MSE shows the effectiveness of the technique. © 2015 IEEE.

In the absence of thermal comfort standards in India, architects and designers have no choice, except to provide air conditioning to meet thermal comfort criteria for achieving green building rating for their projects and thus end up using more energy eventually. Significant Energy saving can be brought about by promoting naturally ventilated buildings as thermally comfortable building by retrofitting them with energy conserving measures for improving thermal performance. This paper analyses effect of various ECBC measures on thermal comfort in naturally ventilated hostel buildings in composite climate with respect to occupants' responses vis- Àvis thermal comfort standards based on the adaptive model of ASHRAE 55-2010 and simulated model so as to prove naturally ventilated buildings to be thermally comfortable due to adaptive opportunities.

Flexible manufacturing system (FMS) promises a wide range of manufacturing benefits in terms of flexibility and productivity. These benefits are targeted by efficient production planning. Part type selection, machine grouping, deciding production ratio, resource allocation and machine loading are five identified production planning problems. Machine loading is the most identified complex problem solved with aid of computers. System up gradation and newer technology adoption are the primary needs of efficient FMS generating new scopes of research in the field. The literature review is carried and the critical analysis is being executed in the present work. This paper presents the outcomes of the mathematical modelling techniques for loading of machines in FMS’s. It was also analysed that the mathematical modelling is necessary for accurate and reliable analysis for practical applications. However, excessive computations need to be avoided and heuristics have to be used for real-world problems. This paper presents the heuristics-mathematical modelling of loading problem with machine processing time as primary input. The aim of the present work is to solve a real-world machine loading problem with an objective of balancing the workload of the FMS with decreased computational time. A Matlab code is developed for the solution and the results are found most accurate and reliable as presented in the paper. © 2016 Growing Science Ltd. All rights reserved.
