Architectural design of experience based factory model for software development process in cloud computing: integration with workflow and multi-agent system

A model which is based on experience factory approach has been proposed earlier, calledEBF-SD, to overcome the limitations of experience management in software developmentdomain. An application prototype, which is then called SDeX, is developed based on theproposed model. The study on correlation analysis indicates that automation do have positiverelationship with other components: knowledge management, cloud, collaboration and portal.This paper further discusses the high level prototype development with the emphasis on thearchitectural design. Automation features are incorporated in the design in which workflowsystem and intelligent agents are integrated, and the facilitation of cloud environment isempowered to further support the automation.Keywords: architectural design; knowledge management; experience factory; workflow;multi-agent system; cloud automation

Regression Analysis on Experience Based Factory Model for Software Development Process

Software organizations are still struggling to reuse the best of their knowledge and experiences in future projects. Often, when there are changes on employee re-assignment, a lot of time and effort are spent for knowledge transfer activities. This however may not assure that all knowledge and experiences are well transferred and shared; some could be missing or misplaced. In this study, a model has been proposed for managing knowledge and experiences based on experience factory approach to provide a more efficient and effective experience management for software development community. Experience Factory is an infrastructure that aims for reuse of products, processes and experiences gained during a system life cycle. A set of components have been identified as the predictors of the model which eventually forms the two main organizations: project organization and experience factory organization. This study further has gone through a correlational survey research to verify the relationship between the identified predictors towards the experience factory goals. Reliability analysis has been conducted to validate the measures, while correlation and regression analyses have been carried out to examine the relationship between the constructs and the goals. Results reveal that reliability of the model is high and construct validity is satisfactory. Experience factory organization is found having more positively significant towards experience goals as compared to project organization; however, there is no significant impact towards the model due to inexistence of causal relation

Customized Fault Management System for Low Voltage (LV) Distribution Automation System

1. Introduction Supply disruption such as overloading will cause interruptions of electricity supply to customers. The technicians have to manually locate the fault point and this tedious work may last for extended periods of time. The other reasons are the lack of use of efficient tools for operational planning and advanced methodology for quick detection of fault, isolation of the faulty section and service restoration. Currently, fault detection, isolation and service restoration takes a long time causing the interruption of supply for a longer duration

Empowering pro-environmental potential among hotel employees: Insights from self-determination theory

Purpose: This research examines the role of green, inclusive leadership, corporate social responsibility, and pro-environmental attitudes on proactive pro-environmental behaviour among hotel employees. It further examines the indirect effects of pro-environmental attitudes between green inclusive leadership, corporate social responsibility, and proactive pro-environmental behaviour, as well as the moderating role of psychological contract breach between pro-environmental attitudes and proactive pro-environmental behaviour. Design/methodology/approach: The participants of this cross-sectional study were employees in the Malaysian hotel industry, and 374 usable questionnaires were used for data analysis. The data were analysed using Partial Least Squares – Structural Equation Modelling. Findings: This study found that green, inclusive leadership, corporate social responsibility, and pro-environmental attitudes significantly influence proactive pro-environmental behaviour. For mediating effects, pro-environmental attitudes have been found to mediate the relationship between corporate social responsibility, green inclusive leadership and proactive pro-environmental behaviour. Research limitations/implications: The research proposes actionable measures to encourage environmentally friendly practices in the hotel sector. For companies to succeed, they must integrate green initiatives with their societal objectives. Pro-environmental mindsets are essential for implementing effective environmental policies, which in turn impact recruitment approaches. The advantages of fostering pro-environmental conduct encompass financial savings, enhanced standing, adherence to regulations, increased innovative thinking and improved workplace well-being. Originality/value: Over time, environmental degradation has been contributed by individual behaviours and the combined actions of businesses and organisations. This study significantly contributed to a new model underpinned by the Self-determination Theory by including new constructs influencing proactive pro-environmental behaviour

The Practice, Challenges and Awareness of Residential Solid Waste Management in the City of Al –Marj, Libya

Solid waste management (SWM) in urban cities has always been a challenge to municipalities. Piles of garbage are seen on the roads and suburbs of highly populated neighbourhoods in the city of Al Marj, Libya. This study aimed at identifying the factors and barriers which influence solid waste management (SWM) in the city of Al Marj, Libya. The data was collected via a questionnaire survey and interview sessions with the residents of the city. A total of 700 questionnaires were distributed randomly; only 482 of these were filled up and returned. The results showed that the city of Al-Marj has a profound solid waste management and awareness problems that must be tackled immediately. The local authorities in charge of the SWM seemed to lack experience as well as facilities required for proper solid waste management. The residents also showed lack of awareness on recycling solid waste, however, they agreed to its importance. The over finding of the study indicated that numerous factors led to the solid waste management problem in the city of Al Marj, Liby

Bromocarbons in the tropical coastal and open ocean atmosphere during the Prime Expedition Scientific Cruise 2009 (PESC 09)

Atmospheric concentrations of very short-lived species (VSLS) bromocarbons, including CHBr3, CH2Br2, CHCl2Br, CHClBr2, and CH2BrCl, were measured in the Strait of Malacca and the South China and Sulu–Sulawesi seas during a two-month research cruise in June–July 2009. The highest bromocarbon concentrations were found in the Strait of Malacca, with smaller enhancements in coastal regions of northern Borneo. CHBr3 was the most abundant bromocarbon, ranging from 5.2 pmol mol−1 in the Strait of Malacca to 0.94 pmol mol−1 over the open ocean. Other bromocarbons showed lower concentrations, in the range of 0.8–1.3 pmol mol−1 for CH2Br2, 0.1–0.5 pmol mol−1 for CHCl2Br, and 0.1–0.4 pmol mol−1 for CHClBr2. There was no significant correlation between bromocarbons and in situ chlorophyll a, but positive correlations with both MODIS and SeaWiFS satellite chlorophyll a. Together, the shortlived bromocarbons contribute an average of 8.9 pmol mol−1 (range 5.2–21.4 pmol mol−1) to tropospheric bromine loading, which is similar to that found in previous studies from global sampling networks (Montzka et al., 2011). Statistical tests showed strong Spearman correlations between brominated compounds, suggesting a common source. Log–log plots of CHBr3/CH2Br2 versus CHBr2Cl/CH2Br2 show that both chemical reactions and dilution into the background atmosphere contribute to the composition of these halocarbons at each sampling point. We have used the correlation to make a crude estimate of the regional emissions of CHBr3 and to derive a value of 32 Gg yr−1 for the Southeast (SE) Asian region (10◦ N–20◦ S, 90–150◦ E). Finally, we note that satellite-derived chlorophyll a (chl a) products do not always agree well with in situ measurements, particularly in coastal regions of high turbidity, meaning that satellite chl a may not always be a good proxy for marine productivity

Cloud-To-Ground Lightning Flashes Under The Influence Of Pollution In Malaysia And Some Countries

The effect of air pollution produced from world war, industrial activities and transportation clearly can change the earth ecology system such as the atmospheric conditions. Base on few studies reported from by researcher in USA, Brazil, Spain and South Korea researcher have proven that the pollution effect can enhance the activity of lightning. Those information above motivate Advanced Multidisciplinary System Technology researcher in UTeM to report the cloud-to-ground lightning flashes in Malaysia the influence of pollution. Particulate Matter (PM10) and Sulfur Dioxide (SO2) concentration were used as gross indicator of Cloud Condensation Nuclei (CCN) and examined in relation to the urban increase in CG lightning activity. PM10 concentration recorded in Subang, Ipoh and Bayan Lepas were 51, 50 and 49μgm/m³ respectively. Meanwhile, SO2 concentration recorded were 8, 7.9, 7.7μgm/m³. The three urban areas have average number of CG lightning flashes of 200, 197 and 184. An analysis related number of CG flashes against pollutants show positive correlation in Malaysia with reading of 0.94. This indicates PM10 and SO2 concentration have high influential factor in enhancement of CG lightning activity in Malaysia

Effect Of Varying Thermal Annealing Temperature On The Characteristics Of Lower And Higher Mg-DOPED GaN

Gallium nitride (GaN)-based light emitting diodes (LEDs) are widely used to produce blue light that, with phosphor, is converted into white light for everyday applications. Despite its high efficiency, the performance of GaN based LEDs is limited by the low electrical conductivity and mobility of magnesium (Mg)-doped GaN due to the presence of magnesium-hydride (Mg-H) complex, which may passivate Mg as an acceptor. In this study, the efficacy of thermal annealing treatment at different temperatures (550°C, 650°C, 750°C and 850°C) was investigated to activate Metal-Organic Chemical Vapor Deposition (MOCVD) grown Mg-doped GaN of different doping levels. Characterization of the treated samples were carried out using Hall effect measurement, atomic force microscopy (AFM) and X-ray diffraction (XRD) for electrical, surface and structural evaluation, respectively
