In the present paper, the effect of Hall currents, compressibility and suspended particles on thermosolutal convection of Rivlin-Ericksen fluid in porous medium is studied. Using linearization theory and normal mode analysis, a dispersion relation is derived. For the case of stationary convection, Rivlin Ericksen fluid behaves like a Newtonian fluid. By analyzing the dispersion relation, it is found that compressibility, suspended particles, Hall currents and permeability destabilizes the convection. The solute gradient and magnetic field stabilizes the same. Oscillatory modes are introduced due to the presence of solute gradient and Hall currents. © 2017 Author(s).

Many different diseases can occur in the liver, including infections such as hepatitis, cirrhosis, cancer and over effect of medication or toxins. The foremost stage for computer-aided diagnosis of liver is the identification of liver region. Liver segmentation algorithms extract liver image from scan images which helps in virtual surgery simulation, speedup the diagnosis, accurate investigation and surgery planning. The existing liver segmentation algorithms try to extort exact liver image from abdominal Computed Tomography (CT) scan images. It is an open problem because of ambiguous boundaries, large variation in intensity distribution, variability of liver geometry from patient to patient and presence of noise. A novel approach is proposed to meet challenges in extracting the exact liver image from abdominal CT scan images. The proposed approach consists of three phases: (1) Pre-processing (2) CT scan image transformation to Neutrosophic Set (NS) and (3) Post-processing. In pre-processing, the noise is removed by median filter. The “new structure” is designed to transform a CT scan image into neutrosophic domain which is expressed using three membership subset: True subset (T), False subset (F) and Indeterminacy subset (I). This transform approximately extracts the liver image structure. In post processing phase, morphological operation is performed on indeterminacy subset (I) and apply Chan-Vese (C-V) model with detection of initial contour within liver without user intervention. This resulted in liver boundary identification with high accuracy. Experiments show that, the proposed method is effective, robust and comparable with existing algorithm for liver segmentation of CT scan images. © 2017 Elsevier B.V.

Image segmentation is the pre-processing task for many computer assisted medical imaging applications. Recently, the Active Contour Models (ACMs) have shown their superiority over traditional low level techniques in segmenting ill-defined medical images. Irrespective of continual development and refinement of these models for the last decades, sensitivity to the initial position of contour and the entrapment within local minima are among the problems inflicted on ACMs. ACM based segmentation is an optimization problem in the sense the objective is to search for a contour with minimal energy. The L'evy flight Firefly Algorithm (LFA) is a nature-inspired meta-heuristic algorithm that is very powerful in solving global optimization problems. In this paper a hybrid approach that integrates ACM with LFA in order to improve its segmentation ability. To validate the performance of the proposed approach, experiments have been conducted on the real CT images of abdomen. The results show the ascendancy of the proposed approach in reaching contour concavities as compared to the traditional ACM. © 2013 IEEE.

The fundamental of motion estimation is that the objects in a frame of video sequence should only move within the original frame to form corresponding objects on the next frame. The concept of block matching method is to partition current frame into a matrix of macro blocks, that are compared with corresponding block and its adjoining neighbors in the last frame to create a vector that determines the motion of a macro block from one position to another in the preceding frame. This movement calculated for all the macro blocks consisting a frame, calculates the motion approximated in current frame. The search region for a perfect macro block equivalent is limited up to s pixels on all fours sides of the corresponding macro block in previous frame. This 's' is known as the search region. Bigger movements require a big s, and the bigger the search region, the process of motion estimation becomes costly. Motion estimation is the main process of block matching algorithms. The motion vector for every block is calculated by obtaining perfect equivalent block of pixels within the search area region in the last frame according to matching criterion. The efficiency of Block Matching Algorithms can be improved by increasing the PSNR of compensated image, changing Block size on Block Matching Algorithm and decreasing number of computations. Block Matching Algorithm is a part in Video Compression Process. Improving the working of Block Matching Algorithm reduces the time taken to compress a video. Motion estimation is used widely in various image sequence coding schemes. It plays a important part in the carrying & storage of video signals at reduced bit rates. © 2015 IEEE.

ABSTRACT: Extensive research and development (R&D) efforts are required to make biofuel production cost-effective. Knowledge management may boost the R&D efforts. Co-processing of petroleum residues, other organic wastes, and fuels may generate cleaner fuels. Presently, an energy management concept of phase-wise transition to biofuels and an energy security management (ESM) model has been suggested as E (Energy) = a ex + b dy/dt + c ez, based on the exponential growth of fossil fuels use with increase in the world population (ex) and differential rate increase in organic wastes use with time, with ez being the exponential increase in biofuels use and a, b, and c are the factors representing the fuel reserves. R&D management involving knowledge management through trained human resources may lead to the development of effective technologies for ushering in the era of bioeconomy. © 2016 Taylor & Francis Group, LLC.

This paper presents a simulation study aimed at evaluating the performances of a typical Flexible manufacturing system (FMS) problems in terms of make span, average flow time, average delay time at local buffers and average machine utilization, subject to different control strategies which include routing flexibilities and dispatching rules. The routing strategies under evaluation are 'No Alternative Routings (NAR)'; 'Alternative Routings Dynamic (ARD)'; and 'Alternative Routings Planned (ARP)'. The ARP rule was introduced into the FMS and coded with C++ program. The above routing strategies are combined with five dispatching rules and studied in different production volumes. Since an FMS usually deals with a variety of products, effects of changing the part mix ratio are also discussed. Simulation study was performed by using ARENA software. Finally results indicate that the 'alternative routings planned' strategy outperforms other routing strategies in general. Copyright © 2014 by ASME.

Energy and environment management is important for energy policy makers as the global warming and climate changes are necessitating carbon management. Coal and biomass are the major energy sources. Focus of energy planners is shifting to renewable fuels such as biofuels (bioeconomy) and clean coal technologies. The present paper describes the need for boosting research and development (R and D) efforts in renewable energy sources. Proper biofuels and clean coal technologies policy and planning are desirable for the sustainable energy technologies management. Strategic management of energy sources would require not only the trained manpower but also knowledge management for the economical and sustainable exploitation of energy resources. Flow scheme of the integrated energy management for cleaner power generation has been suggested by the author presently and a model for clean fuel management and planning has also been proposed. © 2016 Taylor & Francis Group, LLC.
