4-hydroxy Coumarin: a possible ?-radiation dosimeter

The synthesized 4-hydroxy Coumarin was investigated for the purpose of developing a new chemical ?-radiation dosimeter. The compound was exposed to 60Co ?-radiation source at room temperature. The compound dosimeter exhibited good sensitivity to ?-radiation of dose less than 30 Gy and a fairly good linearity of response in dose range 0-25Gy. The present compound may be used as sensitive, and as well as cost-effective dosimeter in 0-25Gy ?-radiation environment.

[PDF] A New Approach for Solving N-Queens Problem with Combination of PMX and OX Crossover Operators

The optimization of the complicated computational problems using algorithms based on population is increased, considerably. In this paper, we use Genetic Algorithm (GA) with a new structure to optimize the optimal solutions to solve N-Queens which is one of the combinatorial optimization problems. For increase the efficiency of GA and prevent from premature convergence, it is used crossover operator. So, to keep the primary population and optimal solution in each generation, it is selected the most fitness population. By performing operations, it is created chromosomes with less conflict. In this case, not only we prevent premature convergence, but also keep the population variety in a balanced scale. In this way, not only we prevent from premature convergence, but also keep the variety of population in balanced way. So, more parts of search space will be explored. The experiment results showed that GA has high efficiency to find optimal solution by combining crossover operators.

[PDF] A novel method for efficient face recognition based on illumination invariant elastic bunch graph matching

Making recognition more reliable under uncontrolled lighting conditions is one of the most important challenges for practical face recognition systems This paper proposes a system which can handle illumination problem of face recognition systems by using “Retinex and color constancy” algorithm. The Retinex and color constancy approach has been plugged with Elastic Bunch Graph Matching (EBGM). The proposed system has been tested on FERET database having more than 1000 face images. The experimental results demonstrate that performance of the proposed system is superior to the known systems with the increase in accuracy.

[PDF] A rare cause of stiff neck: Muscle lymphoma-Case Report and Review of Literature

Muscle lymphoma is a very rare disorder, comprising only a very small subset of lymphoma cases. It can develop either as primary extranodal intramuscular lymphoma or as intramuscular manifestation of disseminated disease. There are characteristic imaging features which, if recognized, can prevent delay in diagnosis and treatment, particularly when not suspected clinically. We herein present a rare case of primary muscle non Hodgkin lymphoma with a description if the associated clinicopathological findings and a review of the relevant literature.

[PDF] A review on software project reliability estimation

Despite the increased importance of the role that reliability plays in commercial product development, most companies are still unable to produce reliable software. The mission of organizations is to provide innovative products at a competitive price to fulfill the needs of very high expectations highly reliable software products for its customers and to do so ahead of its competitors. This requires focus on customer’s satisfaction and software reliability to ensure that desired factor is built into the software product and enable reliable software to be produced. By optimizing best practices for defect removal, organizations can produce high reliability software. In this paper we focus on some research efforts directed at gaining a deeper understanding of the reliability estimation using different algorithms, approaches, simulation methods for software.

[PDF] A Sparsity-Independent Greedy Compressive Sensing algorithm for Cognitive Radio: A subjective approach

This paper presents a Compressive Sensing (CS) greedy iterative algorithm, based on OMP: Sparsity-Independent-OMP (SI-OMP), for varying sparsity spectral conditions. As CS is one of the most essential techniques used by a Cognitive Radio (CR) for efficient usage of spectrum, it is required to be optimally simple, and, still, swift in working. The complexity here refers to the Number of computations a CR is required to make while using such algorithms and, this also, will in turn affect the effective requirement of hardware and power consumption. The proposed algorithm introduces negligible additional complexity, but enables a significant performance improvement in the reconstruction accuracy for arbitrarily varying spectral conditions. The spectrum here is a function of time and frequency both, exhibiting varying sparsity in both the domains.

[PDF] An empirical analysis of Factors of Mechanism of Corporate Governance and Bank-Specific Factors affecting the performance of selected Indian Banks.

An organized Banking sector of any country act as a catalyst for the economic development of the country, Indian Banking sector is the most important component of Indian financial system which work on many dimensions for the economic development of the country including mobilization of savings to the Indian financial system through wide network of Branch Banking that leads to availability of funds to investment purposes and capital formation for the developing country like India, where as the performance of Indian banking sector is not up to the mark from more than five years, so the present study aim is to examined the effect of bank’s specific ratios and selected parameters of corporate governance mechanism on Earning per Share (EPS) of selected eight Indian banks. Earnings per share (EPS) has taken as dependent variables to know financial performance of eight selected Indian Banks. Whereas gross nonperforming assets (GNPA) and Dividend Payout Ratio (DPR) were taken as bank specific independent variables, On the other hand board independency (BIND), Frequency of board meeting (FBM) and capital adequacy ratio (CAR) were considered as parameters of corporate governance. The present research using Panel multiple regression techniques to analyze the factors affecting the earning per share (EPS) during the period 2010 – 2019, On the basis of Hausman test the null hypothesis – random effect model is appropriate is rejected due to (p<0.05)and alt hypothesis-fixed effect model was accepted and found appropriate for the model applied for the study. The study revealed the following result¬- Board independency (BIND) is positively related with the earning per share but statistically insignificant but frequency of bard meetings (FBM) and dividend payout ratio (DPR) are positively related with the EPS as well as statistically significant, capital adequacy ratio (CAR) and gross non-performing assets (GNPA) are negatively related with EPS but CAR is insignificant and GNPA is statistically significant.

[PDF] An outlook about evolution modeling of small world brain functional network simulating memory connection mechanism

In order to understand the character of the brain functional network, we propose a new evolution model to simulate the mechanism of the brain network. With the reference of the memory mechanism, the network was set up by the compression path algorithm and displayed good effect of its characteristic on degree distribution, average path length and clustering coefficient, especially on community.

[PDF] An overview of Blend of Casting Process and Powder Metallurgy Technique as an alternative for manufacturing

The combination of Casting and Powder Metallurgy can promote refined and more uniform microstructures which can result in improved properties and higher isotropy of material. The potential of such blending can be studied by using three important processes viz. Osprey Process, Ceracon Process and Slip Casting Process. These processes can be compared on the basis of microstructure, Austenitizing temperature, and Hardness with Scanning electron microscopy and can be related with conventional processes of manufacturing.
