A new heavy gauge boson, W′, decaying to a muon and a neutrino, is searched for in pp collisions at a centre-of-mass energy of 7 TeV. The data, collected with the CMS detector at the LHC, correspond to an integrated luminosity of 36 pb−1. No significant excess of events above the standard model expectation is found in the transverse mass distribution of the muon–neutrino system. Masses below 1.40...
Information Systems are needed for modernization of ICUs to deliver better health care services. EHR systems can improve the work flow management in health care delivery. This work proposes a secure web enabled system based on a multi-tier architecture for carrying out routine and special operations of Neonatal Intensive Care Unit (NICU). The system adopts a service oriented approach for execution...
A measurement of W+W− production in pp collisions at s=7 TeV and a search for the Higgs boson are reported. The W+W− candidates are selected in events with two leptons, either electrons or muons. The measurement is performed using LHC data recorded with the CMS detector, corresponding to an integrated luminosity of 36 pb−1. The pp → W+W− cross section is measured to be 41.1±15.3(stat)±5.8(syst)±4...
`Separation of Concerns' in the field of Software Engineering has been an important issue for quite some time. And this issue is very much related to Aspect Oriented Software Development. This is so because Aspects happen to be certain concerns that get interleaved with the Core-Functionalities in such a way that they become inseparable. As a result of which the programmer, who is supposed to be concerned...
UML being semi formal in nature, it lacks formal syntax and hence automated verification of analysis and design specifications cannot be done. Verification at early phases of SDLC has gained significant importance because of the possibility of early error detection resulting in reduced costs and time to market. To address this, in this paper we propose a formal grammar for the three of the commonly...
Requirements discovery during project development is known to be the most critical risk in any software project, and managing this is paramount to success in software development. Requirements can change in various ways during the course of a project, and the effect of change on the outcome can differ widely. In this paper we study the effect of different patterns of requirements discovery on a software...
This paper proposes a graph-based approach for the specification of component-based architectures. We have proposed Component Architecture Graph (CAG), a new graphical model for representing UML component diagram. A set of metrics has been defined based on this graph, which will help in measuring several architectural aspects of a system. A case study is presented for presenting the new graphical...
The distributed delivery model has gained immense importance where the actual software is developed in a distributed manner with a common core component and various regional components interfacing with it. This introduces more complexity in software design as sequence diagrams, which implements the use cases are highly interleaved. We propose a new graphical model named Distributed Scenario Graph...
A Unified Modeling Language (UML) use case diagram is a visual tool that provides a way for developers to come to a common understanding with system's end users and domain experts. The behavior of a use case can be specified by describing a flow of events in text for an outsider to understand it easily. The flow of events of a use case is specified in an informal structured text. Therefore, it is...
