Performance Enhancement of Multicore Processors using Dynamic Load Balancing

Introduction of Multi-core Architecture has opened new area for researchers where dynamic load balancing can be applied to distribute the work load among the cores. Multi-core Architecture provides hardware parallelism through cores inside CPU. Its increased performance and low cost as compared to single-core machines, attracts High Performance Computing (HPC) community. The paper proposes a user level dynamic load balancing model for multi-core processors using Java multi-threading and use of Java I/O framework for I/O operations

Application of Linear Programming in Scheduling

Distributed computing virtually combines the scattered interconnected computing resources and satisfies the demand of compute-bound and data-hungry applications. The paper highlights various Distributed Computing Environments (DCE), scheduling techniques and need of incorporation of Dynamic Load Balancing (DLB) in scheduling. The paper also opens a new area of research by introducing Linear Programming as a scheduling technique in DCE

Adaptive Load Balancing Policy for Web Server Custer

The paper highlights the significance of open source software for distributed computing environment and proposes an adaptive load balancing model using open source software for distributed computing environment. The load balancing strategies used by the model are based on load of the system. The proposed algorithm uses current load, response ratio and processor utilization of the nodes of the web server cluster to evaluate the performance

Impact of Cypermethrin on Fingerlings of Common Edible Carp (Labeo rohita)

Laboratory evaluations were made to assess the toxicological and biochemical effect of cypermethrin on fingerlings of common edible freshwater culture carp (Labeo rohita). There was a significant negative (P < 0.05) correlation observed between effective doses of cypermethrin and exposure periods; that is, LC50 values decreased from 0.323 μg/L (6 h) to  > 0.278 μg/L (12 h),  > 0.240 μg/L (18 h) and >0.205 μg/L (24 h). Exposure to sublethal doses of cypermethrin for 24 h and 96 h exposure period caused significant (P < 0.05) time- and dose-dependent alterations in total protein, total free amino acids, nucleic acids, glycogen, pyruvate, and lactate level and in the activity of enzyme protease, alanine aminotransferase, aspartate aminotransferase, acid phosphatases, alkaline phosphatases, acetylcholinesterase, and cytochrome oxidase in liver and muscle tissues of fish. Thus, cypermethrin has potent piscicidal activity against fingerlings of fish Labeo rohita and adversely affects their behavioural patterns, shifting aerobic pathway of fish respiration towards anaerobic pathway and also inhibiting energy production by suppressing ATP synthesis

Two and three-dimensional shock-shock interactions on the blunt leading edges of the hypersonic inlets

The effect of shock impingement on the blunt leading edges of the top and sidewall compression type inlet of a scramjet engine is studied numerically. The impinging shock is caused by the vehicle forebody. The interaction of this forebody shock with the inlet leading edge shock results in a very complex flowfield containing local regions of high pressure and intense heating. This complex flowfield in calculated by solving the Navier-Stokes equations using a finite volume flux splitting technique due to van Leer. To resolve the finer details of the flow structure as well as to predict the surface heat transfer accurately, adaptive grid technique is used in the analysis. Results of the present numerical study are compared with available experimental results

FORMULATION AND EVALUATION OF FAST DISSOLVING TABLETS OF AMOXYCILLIN TRIHYDRATE AND POTASSIUM CLAVULANATE

Objective: The present work is aimed to formulate fast dissolving stable tablet formulation a preferred combination of Amoxycillin trihydrate (Beta-lactum antibiotic) and Potassium clavulanate (Beta-lactum inhibitor) by using various super disintegrants.Methods: Fast dissolving tablets are prepared by direct compression method using super disintegrants i.e. sodium starch glycolate, crospovidone, croscarmellose sodium. Aspartame as a sweetener and trusil mango flavor were used to increase palatability. Reduction in the dose of Amoxycillin trihydrate and Potassium clavulanate tablet was possible by developing fast dissolving tablet. Results: The powder blends were subjected to various pre-formulation evaluations such as, tapped density, bulk density, hausner's ratio, the angle of repose and compressibility index. The prepared Amoxycillin trihydrate and Potassium clavulanate fast dissolving tablets were evaluated for thickness, weight variation, friability, disintegration time, hardness, wetting time and in vitro drug release. All fast dissolving tablet formulations shown uniform weight, hardness and friability data indicates the good mechanical resistance of the fast dissolving tablet. Fast dissolving tablets were disintegrated between 25-50 second and in vitro disintegration time of the best fast disintegrating tablets was found to be 25 second. Conclusion: Amoxycillin trihydrate and Potassium clavulanate fast dissolving tablets were found to be of good quality fulfilling all the needs for fast dissolving tablets. The optimised (F-4) formulation had shown best disintegration time and released profile with a maximum in vitro drug release as compare to marketed preparation at all time intervals of in vitro drug release

T Cell Lymphoma: A Rough Road to Diagnosis

Introduction: Lymphoproliferative disorders are well known for their variable presentation. Peripheral T cell lymphoma not otherwise specified (PTCL-NOS) is one subtype which is especially notorious. It has a variable age of onset, predominantly a nodal presentation and immunohistochemistry (IHC) depicting mature T cells.Presentation of case: We share our experience of a 33 year old patient who presented with mediastinal mass with pericardial effusion. However the histopathology revealed PTCL-NOSConclusion: This case in one of the manifestations of heterogeneity encompassing T cell neoplasms where discordance in clinical and pathological behaviour caused not only diagnostic confusion but also complicated treatment decisions.

Experimental Investigation & Evaluation of Incorporated Material to Set their Optimum Re-Order Point in Kanban Control

In a manufacturing company inventory cost is a significant part of expense. So, the Re-order Point (R.O.P.) of the items must be optimum to reduce its carrying cost. We have study about the inventory and R.O.P. in Nevatia Steel & Alloys Pvt. Ltd. Mumbai and tried to find the optimum R.O.P. by applying VED and XYZ Analysis. Finally, for mathematical modeling we also take help of MatLab
