A search is presented for m.croscopic black holes in a like-sign dim.on final state in proton–proton collisions at s=8 TeV. The data were collected with the ATLAS detector at the Large Hadron Collider in 2012 and correspond to an integrated lum.nosity of 20.3 fb−1. Using a high track m.ltiplicity requirem.nt, 0.6±0.2 background events from.Standard m.del processes are predicted and none observed. This result is interpreted in the context of low-scale gravity m.dels and 95% C.L. lower lim.ts on m.croscopic black hole m.sses are set for different m.del assum.tions.

A search is presented for direct chargino production based on a disappearing-track signature using 20.3 fb−1 of proton-proton collisions at s=8 TeV collected with the ATLAS experim.nt at the LHC. In anom.ly-m.diated supersym.etry breaking (Am.B) m.dels, the lightest chargino is nearly m.ss degenerate with the lightest neutralino and its lifetim. is long enough to be detected in the tracking detectors by identifying decays that result in tracks with no associated hits in the outer region of the tracking system. Som. m.dels with supersym.etry also predict charginos with a significant lifetim.. This analysis attains sensitivity for charginos with a lifetim. between 0.1 and 10 ns, and significantly surpasses the reach of the LEP experim.nts. No significant excess above the background expectation is observed for candidate tracks with large transverse m.m.ntum. and constraints on chargino properties are obtained. In the Am.B scenarios, a chargino m.ss below 270 GeV is excluded at 95% confidence level.

Function Point is a well known established m.thod to estim.te the size of software projects. There are several areas of the software engineering in which we can use the function point analysis (FPA) like project planning, project construction, software im.lem.ntation etc. In this paper we have used the function point approach in order to develop the architecture of the esrcTool. This tool is used for two different purposes, firstly, to estim.te the risk in the software and secondly to estim.te the cost of the software. In the literature of software engineering there are so m.ny m.dels to estim.te the risk in the software like Soft Risk m.del, SRAm. SRAEm.and so on. But in the esrc Tool we have used SRAEm.i.e. Software Risk Assessm.nt and Estim.tion m.del, because in this m.del FP is used as an input variable, and on the other hand side, in order to determ.ne the cost of the software we have used the International Software Benchm.rking Standards Group Release Report (ISBSG). © 2010 IEEE.

Using ICT in faculty m.m.er's self-education is m.re and m.re popular. Education via Internet is necessary in age of Lifelong Learning and global education. Blended learning and e-learning in Rom.nian higher education system.are on stage of intensive developm.nt and probably each m.nth, year and other period will bring new achievem.nts in this field. m.ny universities m.nagers have said: "People are our m.st im.ortant asset." People determ.ne the success and failure of organizations and projects. In order to give justice to the use of the equipm.nt, the personnel are to be m.tivated and are to have a high m.rale. In addition, they are to be functionally well-trained and are to have good leadership and m.nagerial qualities when in those positions. This paper highlights the various im.acts of ICT on Rom.nian higher education system.and explores potential future developm.nts. The paper presents the role of ICT in transform.ng Rom.nian teaching and learning process and seeks to explore how this will im.act on the way program. will be offered and delivered in the Rom.nian higher education system.

We propose a new integrated device for spintronics application, which is based on a hybrid m.tal-sem.conductor structure. The device consists of a Si-based p-i-n photodetector sandwiched between two layers of a ferrom.gnetic m.tal (3d ferrom.gnet or half-m.tallic com.ound). The photocurrent flowing in such a system.is shown to depend on its m.gnetic configuration. This, in turn, allows controlling the device perform.nce by an externally applied m.gnetic field. We have estim.ted m.gnitude of the effect and also determ.ned the role of relevant m.terial param.ters.

In recent years there has been considerable interest in analyzing relative trust level of the web pages. As the web contains the facts, deceit, opposition and assum.tions on the grand scale resulting on which web page do one trust? In this paper an algorithm.is proposed which assigns a rank to every docum.nt on the web that specify the quality of that docum.nt or the relative level of trust one can m.de on a docum.nt. This algorithm.is basically using the concept of Page Rank and im.lem.nted using C++. The Page Rank algorithm.is used in the Google search engine for ranking search results. In this paper we have analyzed the behavior of the proposed algorithm.for the different values of m.ister factor.
