Simple network management protocol co- existence with hydrocarbon process automation communication real-time network

Hydrocarbon Process Automation Applications (HPAA) utilizes Real-time network connecting process instrumentations, controllers, and real-time logic control applications. Conventional practice is to dedicate a real-time network for process automation applications and prevent other applications from utilizing the same infrastructure. An important application that can help optimize, improve network performance, and provide rapid response time in network diagnostics and mitigation is Simple Network Management Protocol (SNMP). This paper addresses the co-existence of SNMP traffic with real-time applications. The impacts of activating this protocol with the real-time HPAA utilizing high speed Ethernet network design will be examined. Empirical data for an implemented Hydrocarbon process automation system will be used to illustrate the interdependency of application performance, traffic mix, and potential areas of improvements. The outcomes of this effort demonstrate the co-existence of SNMP with HPPA, given special considerations (i.e., bandwidth, number of applications, etc.)

Diffusion of social cognitive theory in information systems research: A bibliometric study

Recently, Social Cognitive theory (SCT) has been widely adapted across various disciplines in business and management as well as Information Systems (IS) research. In IS, the use of SCT remains in its early stages. Few bibliometric analyses have been published on mapping theories across previous literature. However, to date factors related to literature review mapping in relation to SCT in IS have not been much examined. This paper aims to investigate the expliotiation of SCT in IS research based on bibliometric analysis. In this study a biblimetric analysis is conducted on previous literature reviews/abstracts based on Association of Business Schools (ABS) journal rankings from Information Management field perspective. 62 articles in Information Management field have utilised SCT were published in 17 (out of 53 journals) between 1995 and 2010. The study findings has identified that the organisation/firm and actors as a unit of analysis, positivist paradigm, empirical and quantitative research as well as survey method were used significantly in combination with SCT in IS studies. This bibliometric study will provide the needed platform for a better understanding of high quality research activities. Consequently, this can be used as an indicator to measure research quality and the impact of future direction and exploitation of SCT in IS research

The impact of national culture on e-government implementation: A comparison case study

Over the past decade there has been increasing interest in the IS research literature on the impact of cultural differences on the development and use of information and communications technologies (Ives & Jarvenpaa, 1991; Shore & Venkatachalam, 1995; Tractinsky & Jarvenpaa, 1995, Myers and Tan, 2002, Ali and Brooks, 2008). In this paper the authors explore the influence of national culture on eGov implementation. The authors have conducted a comparative case study in two different countries the UK as a developed country and Sari Lanka as a developing country. The research findings highlight the potential influence of cultural differences on eGov implementation

Blind image separation based on exponentiated transmuted Weibull distribution

In recent years the processing of blind image separation has been investigated. As a result, a number of feature extraction algorithms for direct application of such image structures have been developed. For example, separation of mixed fingerprints found in any crime scene, in which a mixture of two or more fingerprints may be obtained, for identification, we have to separate them. In this paper, we have proposed a new technique for separating a multiple mixed images based on exponentiated transmuted Weibull distribution. To adaptively estimate the parameters of such score functions, an efficient method based on maximum likelihood and genetic algorithm will be used. We also calculate the accuracy of this proposed distribution and compare the algorithmic performance using the efficient approach with other previous generalized distributions. We find from the numerical results that the proposed distribution has flexibility and an efficient resultComment: 14 pages, 12 figures, 4 tables.

Colored bosons on top FBA and angular cross section for ttˉt \bar t production

With full data set that corresponds to an integrated luminosity of 9.4 fb$^{-1}$, CDF has updated the top quark forward-backward asymmetry (FBA) as functions of rapidity difference $|\Delta y|$ and $t\bar t$ invariant mass $M_{t\bar t}$. Beside the sustained inconsistency between experiments and standard model (SM) predictions at large $|\Delta y|$ and $M_{t\bar t}$, an unexpected large first Legendre moment with $a_1= 0.39\pm 0.108$ is found. In order to solve the large top FBA, we study the contributions of color triplet scalar and color octet vector boson. We find that the top FBA at $|\Delta y| >1$ and $M_{t\bar t} > 450$ GeV in triplet and octet model could be enhanced to be around 30% and 20%, whereas the first Legendre moment is $a^{\bf Di}_1= 0.38$ and $a^{\bf Axi}_1= 0.23$, respectively.Comment: 13 pages, 5 figures; references adde

Pairwise quantum and classical correlations in multi-qubits states via linear relative entropy

The pairwise correlations in a multi-qubit state are quantified through a linear variant of relative entropy. In particular, we derive the explicit expressions of total, quantum and classical bipartite correlations. Two different bi-partioning schemes are considered. We discuss the derivation of closest product, quantum-classical and quantum-classical product states. We also investigate the additivity relation between the various pairwise correlations existing in pure and mixed states. As illustration, some special cases are examined.Comment: 19 pages, To appear in International Journal of Quantum Informatio
