Cost estimation for Service Oriented Architecture (SOA) has not been addressed properly in the existing literatures. Most cost estimation approaches published in the literatures are more guidelines than actual practical estimation techniques. On the other hand, traditional software cost estimation techniques don’t fit SOA characteristics properly. In this paper, a phased effort distribution in ...

This paper brings forward a service oriented perspective, based on practical experiences from designing information systems (IS) as services. Viewing IS as services are beneficial but still an unexplored approach in organizations. In this paper, we present an analysis of Enterprise Resource Planning (ERPs) systems through the perspective of Service Oriented Architecture (SOA). This paper contri...

SOA has been adopted by enormous number of organizations world-wide. This study has investigated significant factors which affect SOA adoption in positive and negative manner. Unlike the previous similar studies, where they focused on qualitative analysis for SOA adoption, this study conducted a quantitative analysis to investigate the relationship between the adoption of SOA and the performanc...

Aged atmospheric volatile organic matter create secondary aerosols (SOA), influencing the indirect effect of aerosols. A difference in viscosity and hydrophobicity SOA may be primary cause changes hygroscopicity.

Organic gases undergoing conversion to form secondary organic aerosol (SOA) during atmospheric aging are largely unidentified, particularly in regions influenced by anthropogenic emissions. SOA dominates the atmospheric organic aerosol burden and this knowledge gap contributes to uncertainties in aerosol effects on climate and human health. Here we characterize primary and aged emissions from r...

The chemical and physical differences of secondary organic aerosol (SOA) formed at select isothermal temperatures (278 K, 300 K, and 313 K) are explored with respect to density, particle volatility, particle hygroscopicity, and elemental chemical composition. A transition point in SOA density, volatility, hygroscopicity and elemental composition is observed near 290–292 K as SOA within an envir...

Service-Oriented Architecture (SOA) is a paradigm to implement loosely-coupled, platform-independent distributed software systems using communicating services. Currently, SOA is well-recognized as an established architectural paradigm for distributed systems. Specific design principles for SOA have been recognized as fundamental for implementation in practice. In this article, a systematic lite...

The photodegradation of secondary organic aerosol (SOA) material by actinic UV radiation was investigated. SOA was generated via the dark reaction of ozone and d-limonene, collected onto quartz-fiber filters, and exposed to wavelength-tunable radiation. Photochemical production of CO was monitored in situ by infrared cavity ring-down spectroscopy. A number of additional gas-phase products of SO...

SOA governance has a critical role in achieving success and realizing the benefits of SOA. Without effective SOA governance, organizations will experience some significant challenges including difficulties in designing effective decision structures and managing services. To address SOA challenges, organizations require a comprehensive SOA governance framework to implement management and control...
