Business intelligence (BI) architecture based on service-oriented architecture (SOA) concept enables enterprises to deploy agile and reliable BI applications. However, the key factors for implementing a SOA-based BI architecture from technical perspectives have not yet been systematically investigated. Most of the prior studies focus on organisational and managerial perspectives rather than tec...

The concept of Service Oriented Architecture (SOA) has had a significant impact not only on software engineering but on the analysis of an organization’s business layer as well. It contributes to developing information systems that are compatible with the needs of agile organizations. This fact brings us to investigate the new approach of Business-IT Alignment (BITA) by utilizing SOA features. ...

This study investigated the DTT activity of different types of SOA (toluene, TMB, isoprene, a-pinene) formed in the presence of NOx. Experiments are conducted in an outdoor chamber facility with different levels of NOx. Results showed that in the presence of relatively higher levels of NOx, DTT activity of toluene SOA is 2-5 times higher than other SOA. Isoprene SOA has lower DTT with increasin...

As a matter of fact, SOA-based systems have a huge internal complexity due to plenty of services. On the one hand, this complexity enables and strongly supports the flexible alignment of the enterprise architecture with business processes. On the other hand, it requires a special management and control framework – provided by SOA Governance. For IT Governance, many accepted approaches exist. In...

During the last years, several approaches for the design of software services in service-oriented architectures (SOA) have been proposed. Often these approaches are too rough or too academic to provide guidance for real world SOA projects. Moreover, since the existing SOA design approaches are often not sufficiently validated, their successfulness in practice can be doubted. The research presen...

The purpose of this discussion paper is to explain why we are convinced that Service Oriented Architecture (SOA) is the best alternative to resolve the data movement interoperability gap that exists between LMSs and LORs. An example of a successful implementation of SOA in the Healthcare and Insurance industries is discussed, followed by a recent endorsement of SOA by the Instructional Manageme...

Laboratory chambers, invaluable in atmospheric chemistry and aerosol formation studies, are subject to particle and vapor wall deposition, processes that need to be accounted for in order to accurately determine secondary organic aerosol (SOA) mass yields. Although particle wall deposition is reasonably well understood and usually accounted for, vapor wall deposition is less so. The effects of ...

Abstract In runoff prediction, the prediction accuracy is often affected by non-linear and non-stationary characteristics of series. this study, a coupled forecasting model proposed that decomposes original series an improved complete ensemble Empirical Mode Decomposition (EMD) (ICEEMDAN) combined with wavelet decomposition (WD) then forecasts monthly using support vector machine (SVM) optimize...

Secondary organic aerosol (SOA) formation from photooxidation of α-pinene has been investigated in a photochemical reaction chamber under varied inorganic seed particle acidity levels at moderate relative humidity. The effect of particle acidity on SOA yield and chemical composition was examined under highand low-NOx conditions. The SOA yield (4.2–7.6 %) increased nearly linearly with the incre...

Secondary organic aerosol (SOA) can reside in the atmosphere for a week or more. While its initial formation from the gas-phase oxidation of volatile organic compounds tends to take place in the first few hours after emission, SOA can continue to evolve chemically over its atmospheric lifetime. Simulating this chemical aging over an extended time in the laboratory has proven to be challenging. ...
