EFFICIENT QUANTUM CIRCUITS FOR PERFECT AND CONTROLLED TELEPORTATION OF n-QUBIT NON-MAXIMALLY ENTANGLED STATES OF GENERALIZED BELL-TYPE

Abstract: An efficient and economical scheme is proposed for the perfect quantum teleportation of n-qubit non-maximally entangled state of generalized Bell-type. A Bell state is used as the quantum channel in the proposed scheme. It is also shown that the controlled teleportation of this n-qubit state can be achieved by using a GHZ state or a GHZ-like state as quantum channel. The proposed schemes are economical because for the perfect and controlled teleportation of n-qubit non-maximally entangled state of generalized Bell-type, we only need a Bell state and a tripartite entangled state respectively. It is also established that there exists a family of 12 orthogonal tripartite GHZ-like states which can be used as quantum channel for controlled teleportation. The proposed protocols are critically compared with the existing protocols.

An Automated approach for Bug Categorization using Fuzzy Logic

Abstract: Various automated techniques built to benefit software developers, bug triagers, stakeholders and users in open source systems, utilize information placed in issue tracking systems. The success of these techniques depends largely on the quality of information present in the issue reports. Assigning correct label to issue reports is one of the quality concerns. Previous empirical studies conducted on the issue reports show that most issues are either mislabeled or are not labeled at all. Thus, in order to enhance quality of issue reports, there is a strong need to propose an automated and accurate bug labeling approach. A label can be a bug, feature enhancement or other request. In this paper, we propose an automated approach to label an issue either as bug or other request based on fuzzy set theory. Experiments are conducted on issue repository of three open source software systems: HTTPClient, Jackrabbit and Lucene. We have achieved an accuracy of 87%, 83.5% and 90.8% and F-Measure score of 0.83, 0.79 and 0.84 respectively. This is a considerable improvement as compared to the earlier reported work on these three datasets using topic modeling approach.

Protic ionic liquid-based gel polymer electrolyte: structural and ion transport studies and its application in proton battery

Abstract: Proton-conducting free standing gel polymer electrolyte (GPE) films containing protic ionic liquid, 1-butyl-3-methylimidazolium hydrogen sulphate, immobilized in blend of poly(vinylidenefluoride-co-hexafluoropropylene) and poly(vinylpyrrolidone) have been prepared by solution-cast technique. Films have been characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscope (SEM), differential scanning calorimetry (DSC), complex impedance spectroscopy, and cyclic voltammetry. Ionic conductivity of the semicrystalline and porous GPE films has been obtained as ~3.9 × 10−3 S cm−1 at room temperature. Protonic nature of conduction in the films has been established by performing cyclic voltammetry and complex impedance spectroscopy on the cells having both blocking (stainless steel) and both reversible electrodes (Zn + ZnSO4.7H2O). The electrochemical stability window of the films has been found as ~3.8 V. The highest conducting film has been used as a separator and proton conductor to fabricate a proton battery of configuration Zn + ZnSO4.7H2O |GPE film| PbO2 + V2O5. The battery shows an open circuit voltage of ~1.62 V. Energy density of the cell has been obtained as 35.2 W h kg−1 for low current drain. Rechargeability of the cell has been tested for ten cycles. The maximum discharge capacity of the cell has been obtained as ~2.50 mA h g−1 during the first discharge cycle.

Parallel crawler architecture and web page change detection

Abstract: In this paper, we put forward a technique for parallel crawling of the web. The World Wide Web today is growing at a phenomenal rate. It has enabled a publishing explosion of useful online information, which has produced the unfortunate side effect of information overload. The size of the web as on February 2007 stands at around 29 billion pages. One of the most important uses of crawling the web is for indexing purposes and keeping web pages up-to-date, later used by search engine to serve the end user queries. The paper puts forward an architecture built on the lines of client server architecture. It discuses a fresh approach for parallel crawling the web using multiple machines and integrates the trivial issues of crawling also. A major part of the web is dynamic and hence, a need arises to constantly update the changed web pages. We have used a three-step algorithm for page refreshment. This checks for whether the structure of a web page has been changed or not, the text content has been altered or whether an image is changed. For The server we have discussed a unique method for distribution of URLs to client machines after determination of their priority index. Also a minor variation to the method of prioritizing URLs on the basis of forward link count has been discussed to accommodate the purpose of frequency of update.

Effect of Introduction of Fault and Imperfect Debugging on Release Time

Abstract: One of the most important decisions related to the efficient management of testing phase of software development life cycle is to determine when to stop testing and release the software in the market. Most of the testing processes are imperfect once. In this paper first we have discussed an optimal release time problem for an imperfect faultdebugging model due to Kapur et al considering effect of perfect and imperfect debugging separately on the total expected software cost. Next, we proposed a SRGM incorporating the effect of imperfect fault debugging and error generation. The proposed model is validated on a data set cited in literature and a release time problem is formulated minimizing the expected cost subject to a minimum reliability level to be achieved by the release time using the proposed model. Solution method is discussed to solve such class of problem. A numerical illustration is given for both type of release problem and finally a sensitivity analysis is performed.
