Magnetic resonance Image (MRI) is a medical image method use in radiology to visualize internal body structures like tissues. MRI method provides high-quality contrast effect to visual tissues of brain and MRI contrast is enhancing appearance of tumors in brain. In this survey compared the CLIC, EM, AFCM, Bias Field Estimation, SFKFCM, MFCM and FLGMM methods for accurate brain segmentation in MRI images. CLIC method to evaluate metric tissue classification and estimate bias field minimizing energy, optimal bias field derived smoothness of CLIC method. It’s applied for fully automated applications. AFCM applied on corrupted images in reality accurate in classification and partial volume effect. MR data corrupted truth brightness variation in each component. AFCM implementation is faster than other methods one major problem in AFCM method is to look for clusters of the same shape, size and increased complexity. Bias corrected FCM method with spatial neighborhood regularization period and its time taking; lacks robustness to noise is main problem of the method. In GKFCM method with a spatial bias correlation can automatically learn parameters by prototype driven learning scheme and this method is effective more robust to noise. SFKFCM method for segmenting brain MRI images and correcting spurious variations, to improve the separability of observed data, fast clustering scheme improve speed up process and execution time is reduced improved clustering results. MFCM for adaptive segmentation and intensity correlation of MR images and automation available for the segmentation of MR images into tissues classes correcting interscan intensity inhomogenetics. MFCM leads to increased improvement in quality of 3D brain structures and visualization. GMM voxel intensities in each target region, its lack of taking spatial information and uncertainty data may produce poor segmentation result. To overcome problem in segmentation FGMM concept is proposed for uncertainty data and parameter quality improvement. The integration of the weighted GMM energy functions in the entire image and uses a truncated Gaussian kernel function to incorporate spatial constraints into local GMM employ the fuzzy membership function to balance each GMM segmentation process. FGMM reduced noise, low contrast, bias field and improved segmentation result compared with all other methods proposed by previous researches.

The Ab-initio and charge density analysis of Au and thiol substituted Dicyclopentyl-Cyclohexan (DCC) molecular nanowire, was carried out using high level Density Functional Theory (DFT) with the help of LANL2DZ basis set coupled with the Bader’s theory of atoms in molecules . All the studies were carried out in the presence of an applied electric field which is gradually increasing from 0.05–0.26VÅ?1. The effect of the applied electric field on the geometrical and the topological analysis of the molecular wire is thoroughly made and studies were made to charcterise the bonds, especially the terminal bonds, which shows ionic nature. The variation in the dipole moment as a consequence of the polarization caused by the applied EF is thoroughly studied. HOMO-LUMO analysis was carried out to determine the way the molecule interacts with other species which may initiates the conductivity. The I–V characteristics of the molecule have been studied for various applied fields for finding the conducting nature of the molecule-electrode-molecule system. The molecular electrostatic potential surface was plotted over the geometry of the molecule to elucidate the reactivity of the molecule.

The abnormal right coronary artery originating from the left coronary system is an extremely rare variation of isolated single coronary artery. It is often a benign entity and the patients remain asymptomatic. Nevertheless, it can lead to sudden death during exertion. The treatment of this coronary anomaly may be medical, percutaneous and/or surgical. We present here a right coronary artery originating from the proximal left anterior descending artery in the first case and from the left main coronary artery in the second case. Both patients were seen to have an acute coronary syndrome with multi-vessel coronary artery disease.

Reliability assessment popularly known as Weibull analysis is an exercise primarily concerned with reliability estimation and prediction with which failure process of a system can better be analyzed. Many situations like modeling failure processes, decision of effective maintenance policy, estimation of maintenance float factors, downtime assessment and reduction greatly rely on the parameters of the life distributions fitted to the failure data. As the Weibull distribution involves transcendental equation, determining parameters is quite difficult task. To this effect, a Nomograph is developed and presented in this paper to closely determine the Weibull parameters. The paper articulates the development of Nomograph and procedure for its implementation. Results and discussions carried out proves statistically that the results obtained using the Nomograph are better than the commonly used its counterparts.

- A cloud consists of several elements such as clients, cloudlets, datacenter, distributed servers etc. While Cloud computing is a term, which involves virtualization, distributed computing, networking and software and web services. Centrally, the issue is to establish an effective load balancing in cloud. There are two types of load balancing algorithms available one is Static and other is Dynamic. In this paper we have studied three different Static load balancing algorithms i.e. Round Robin, Throttled, and Optimal. To compare each algorithm we have prepared a set-up and implemented each algorithm. Finally, an analysis has been done about the three implemented algorithms to find the best algorithm in terms of overall response time of cloudlet and Datacenter Processing time of cloudlet.

Good featured glassy bismuth selenide (Bi2Se3) thin films were prepared from solutions having bismuth nitrate, triethanolamine and sodium selenosulphate at room temperature by chemical bath deposition technique. The crystalline structure, surface morphology, electrical and optical properties of these Bi2Se3 thin films were investigated as a function of annealing process. X-Ray diffraction studies resulted in Bi2Se3 thin films with amorphous structure at room temperature (RT) and growth in film was found by annealing with hexagonal crystal structure. A uniform sphere-like morphology was observed from scanning electron microscopy upon annealing. Optical absorption studies revealed that a direct band gap of 1.11 eV for as-deposited Bi2Se3 films and is drops to 1.02 eV by annealing in air at 2000C for one hour. Moreover the absorption edge shifting toward longer wavelength associated with crystallinity development of annealed film. As-deposited, the thin films show resistivity of approximately 6k?/cm2 decreases upon annealing. From temperature-resistance measurements Bi2Se3 thin films are distinctive semiconductor material upon annealing, with calculated activation energies of 0.18eV and 0.9eV at lower and higher temperature respectively. In photoconduction studies after annealing, the films display organized rise in the photocurrent with applied voltage than in the as-prepared films. This enrichment in conductivity results from crystallinity development along with partial loss of selenium. This may accelerate various promises for the usage of these films by chemical bath deposition method.
