A New Modified Collection Selection Algorithm using Optimal Term Weight for Web based Applications

As the number of electronic data collections available on the internet increases so does the difficulty of finding the right collection for a given query Often the first time user will be overwhelmed by the array of options available and will waste time hunting through pages of collection names followed by time reading results pages after doing an adhoc search Collection selection using optimal weight methods try to solve this problem by suggesting the best subset of collections to search based on a query This is of importance to fields containing large number of electronic collections which undergo frequent change and collections that cannot be fully indexed using traditional methods such as spiders This paper presents a solution to these problems of selecting the best collections and reducing the number of collections needing to be searche

Design of Fractional Order Digital Differentiators and Integrators Using Indirect Discretization

Mathematics Subject Classification: 26A33, 93B51, 93C95In this paper, design of fractional order digital differentiators and integrators using indirect discretization is presented. The proposed approach is based on using continued fraction expansion to find the rational approximation of the fractional order operator, s^α. The rational approximation thus obtained is discretized by using s to z transforms. The proposed approach is tested for differentiators and integrators of orders 1/4 and 1/2. The results obtained compare favorably with the ideal characteristics

Mimo Detection

The use of digital wireless communication systems has become more and more common during recent years. A multiple-input-multiple-output (MIMO) system techniques can be implemented to enhance the capacity of a wireless link. We have investigated the performances of MIMO detectors : Linear detectors(ZF detector, MMSE detector), SIC(Successive Interfer- ence Cancellation) signal detectors, Maximum Likelihood detector, Sphere decoding. In SIC signal detection we use MMSE weight matrix

A Revise On Ambler Stream Behavior Beside Pavement

We can find mixed traffic conditions, which mean that the flow routes include all kinds of vehicles like bicycles, bikes, cars, etc. During peak hours, the influx of NMVs is high. The presence of NMV in the transportation system affects traffic characteristics such as speed, volume and river flow. In order to plan a route, it is essential to understand how to travel. For mixed traffic conditions, the river behaviour is difficult to understand. In this article, an attempt is made to study the behavioural characteristics of NMVs in river mixtures. The entire project consists of two parts. The first is the sample section and the last is the sample section test. The first part of the study includes studying the basic foundations and finding potentials of the group and collateral settlement of the group to obtain the information obtained from the various parts of Guntur. The change in NMV ratio was viewed as a problem present in the model such as velocity, density, and flow. In a background study, it was observed that in one sector of transport traffic, the large number of NMVs occupying the left side and MVs occupying most of the area due to our Indian transport behaviour are left-handed and easy for the MV to pass slowly. In the case of two lanes intersecting, the traffic limit is available in the middle section but the lower part is in the left and right parts in light of the fact that vehicles are in fill in that

MHD Boundary Layer Slip Flow over a Flat Plate with Soret and Dufour Effects

The present paper studies the effects of Soret and Dufour on MHD boundary layer slip flow over a flat plate. The governing partial differential equations are converted to a set of nonlinear ordinary differential equations by using similarity transformations. Then, these equations are solved numerically by implicit Finite Difference Scheme. The numerical solutions for Velocity, Temperature and Concentration profiles for the related essential physical parameters are visualized through graphs and discussed. Results show that the velocity rises whereas the temperature and concentration reduces with the respective slip parameters. The increase in Soret number or decrease in Dufour number reduces the temperature and enhances the concentration of the fluid

Bacterial flora associated with the selected life stages and organs of farmed giant freshwater prawn Macrobrachium rosenbergii (de Man)

Bacteria associated with different life stages of giant freshwater prawn (Macrobrachium rosenbergii de Man) were analyzed. The gill, hepatopancreas, haemolymph of brood and juveniles as well as the egg, larvae and larval rearing water were sampled to understand the quantity and the quality of bacteria associated with the animals.A total number of 93 representative isolates were identified. The identified bacterial isolates could be distributed in to 14 genera. A mean bacterial total plate count (TPC) of 4.5x105 colony forming units (cfu) g-1 in eggs, 6.0x106 cfu g-1 in larvae and 4.6x105 cfu ml-1 in water were observed. Among all the organs highest TPC of 3.5x107 cfu g-1 were observed in juvenile’s gills. The brood haemolymph was found to be devoid of any bacteria. Identification of isolates representing different colony morphotype indicated that 89.77% of the bacterial population was gram negative dominated by Aeromonas hydrophilla (16.74%), Enterobacter aerogenes (12.09%) and Citrobacter frundii (10.16%). Among Gram-positive bacteria Bacillus, Streptococcus and Micrococcus were identified. Study of quantitative and qualitative aspects of bacterial prevalence with the different life stages of M. rosenbergii would be helpful in identification of disease causing bacteria and therefore in better management of M.rosenbergii culture

Estimation and Determinants of Chronic Poverty in India : An Alternative Approach

The paper conceptualizes chronic poverty by using the spaces of income and nutrition and estimates its incidence among states and social groups. It also aims to improve our understanding of the determinant of chronic poverty by considering economic, demographic and social factors. It attempts to answer the following questions : How important a determinant of chronic poverty is household income? What factors inhibit escape from chronic poverty? How different are the other poor from chronic poor? The analysis uses the unit level NSS and NFHS data.Chrinic Poverty, India
