Service-oriented architecture (SOA) is an emerging IT strategy. It is an architectural style for building loosely coupled distributed systems that deliver application functionality as services. Currently there is little academic research published on SOA. As a result, we know little about what factors affect SOA implementation such that reported benefits can be achieved. To fill this gap, we st...

This study evaluates the significance of glyoxal acting as an intermediate species leading to secondary organic aerosol (SOA) formation from aromatic hydrocarbon photooxidation under humid conditions. Rapid SOA formation from glyoxal uptake onto aqueous (NH4)2SO4 seed particles is observed in agreement with previous studies; however, glyoxal did not partition significantly to SOA (with or witho...

A new model for predicting the UV-visible absorption spectra of secondary organic aerosols (SOA) has been developed. The model consists of two primary parts: a SOA formation model and a semiempirical quantum chemistry method. The mass of SOA is predicted using the PHRCSOA (Partitioning Heterogeneous Reaction Consortium Secondary Organic Aerosol) model developed by Cao and Jang [Environ. Sci. Te...

UNLABELLED The ozonolysis of terpenoids generates secondary organic aerosol (SOA) indoors. Models of varying complexity have been used to predict indoor SOA formation, and many models use the SOA yield, which is the ratio of the mass of produced SOA and the mass of consumed reactive organic gas. For indoor simulations, the SOA yield has been assumed as a constant, even though it depends on the ...

Nowadays, service-oriented architecture (SOA) is used as an efficient solution to integrate distributed applications in an enterprise. In a SOA-based environment, security is one of the most important issues that must be considered on account of loosely coupled nature of SOA. However, there are several approaches and technologies for securing services such as WS-Security, SAML, and etc. SOA bri...

A simplified parameterization for secondary organic aerosol (SOA) formation in polluted air and biomass burning smoke is tested and optimized in this work, towards the goal of a computationally inexpensive method to calculate pollution and biomass burning SOA mass and hygroscopicity in global and climate models. A regional chemistry-transport model is used as the testbed for the parameterizatio...

Service oriented architecture (SOA) and shared services (SS) have been widely studied in the information technology literature. However, there is a lack of tools for shared services management (SSM) to apply SOA. This paper proposes an ontological map for SSM to apply SOA. This mapping approach, based on the well-known Zachman framework of information architecture, specifies the ontological per...

Secondary organic aerosol (SOA) nearly always exists as an internal mixture, and the distribution of this mixture depends on the formation mechanism of SOA. A model is developed to examine the influence of using an internal mixing state based on the mechanism of formation and to estimate the radiative forcing of SOA in the future. For the present day, 66% of SOA is internally mixed with sulfate...

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...
