Constraining the Parameters of New Variable Modified Chaplygin Gas Model

Abstract: Assuming the flat FRW universe in Einstein’s gravity filled with New Variable Modified Chaplygin gas (NVMCG) dark energy and dark matter having negligible pressure. In this research work we analyze the viability on the basis of recent observation. Hubble parameter H is expressed in terms of the observable parameters H 0, $\varOmega_{m}^{0}$ and the model parameters A 0, B 0, C 0, m, n, α and the red shift parameter z. Here we find a best fitted parameter range of A 0, B 0 keeping 0≤α≤1 and using Stern data set (12 points) by minimizing the χ 2 test at 66 %, 90 % and 99 % confidence levels. Next we do the joint analysis with BAO and CMB observations. Again evaluating the distance modulus μ(z) vs redshift (z) curve obtained in the model NVMCG with dark matter with the best fitted value of the parameters and comparing with that derived from the Union2 compilation data.

First Ply Failure of Laminated Composite Conoidal Shell Roofs Using Geometric Linear and Nonlinear Formulations

Abstract: A detailed review of literature on failure of composite shells shows that no research report is available on failure of laminated conoidal shells using geometrically nonlinear formulation. The present paper aims to fill the lacuna and reports first ply failure of moderately thin composite conoidal shells. A number of parameters like boundary condition, stacking order and lamination are varied to study the failure loads, failure locations and failure modes/tendencies of the shell. The paper concludes with a set of meaningful engineering design guidelines, which are proposed keeping the serviceability criterion in mind.

Micro-Bump Assignment for Efficient Routing on Re-Distribution Layer (RDL) in 3D-ICs

Abstract: RDL (Re-Distribution Layers) routing from the IO pads to micro-bumps plays an important role for transmitting signal between two adjacent layers in 3D IC. The quality of RDL-routing strongly depends on the positions of micro-bumps between two adjacent dies. Initially, I/O pads are assigned to micro-bumps and then single-layer routing is performed over the two RDLs that are adjacent to two respective layers. We propose an improved method for RDL-routing in 3D IC. Experimental results show that 100% routability can be achieved with reduced wire-length for all five test-cases that we have studied.

A Novel Approach for Designing Indian Regional Language Based Raw-Text Extractor and Unicode Font-Mapping Tool

Abstract: Extracting specific information from a collection of documents is called Information Extraction (IE). In general, the information on the web is well structured in HTML or XML format. And the work of IE from structured documents (in HTML or XML), basically uses learning techniques for pattern matching in the content. In this paper, we have proposed a novel approach for interactive information extraction technique. Here, we have described how this approach enables any naive user to extract Indian regional language based document from a web document efficiently which is quite similar to a standard search engine. It is just similar to a pre-programmed information extraction engine.

Developer involvement considered harmful?: an empirical examination of Android bug resolution times

Abstract: In large scale software development ecosystems, there is a common perception that higher developer involvement leads to faster resolution of bugs. This is based on conjectures around more ``eyeballs" making bugs ``shallow" -- whose validity and applicability are not without dispute. In this paper, we posit that the level of developer attention as well as its extent of diversity influence how quickly bugs get resolved. We report results from a study of 1,000+ Android bugs. We find statistically significant evidence that attention and diversity have contrasting relationships with the resolution time of bugs, even after controlling for factors such as interest, importance, dependency etc. Our results can offer helpful insights on team dynamics and project governance.
