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...

Despite the increasing popularity of Service-Oriented Architecture (SOA), mixed outcomes about SOA implementation have often been reported. The key research question to be answered in this study is how various factors, while interacting with each other over time, affect the dynamics of the SOA implementation and certain organizational challenges may occur in the implementation process. To devel...

The thermally induced evaporation of secondary organic aerosol (SOA) has been characterized for SOA formed from the dark ozonolysis of α-pinene at initial mass concentrations ranging from 1 to 800 μg m. Temperaturedependent particle size distributions were measured using a thermodenuder and the resulting mass thermograms were compared between the SOA formed at the various SOA mass concentration...

A fundamental question in vision research is whether visual recognition is determined by edge-based information (e.g., edge, line, and conjunction) or surface-based information (e.g., color, brightness, and texture). To investigate this question, we manipulated the stimulus onset asynchrony (SOA) between the scene and the mask in a backward masking task of natural scene categorization. The beha...

Benefiting from the technology based strategies, Service-Oriented Architecture (SOA) has been able to achieve the general goals such as agility, flexibility, reusability and efficiency. Nevertheless, technical conditions alone cannot guarantee successful SOA implementations. As a valuable and necessary supplement, the space of technology independent strategies should also be explored. Through t...

While there are several efforts underway to provide security for the Service Oriented Architecture (SOA), there is no specification or standard defined to provide authorization services for the SOA. The SOA comprises of Web services and business process workflows built using Web services. Based on our analysis of existing authorization frameworks and policy specification models for the SOA, we ...

The Service Oriented Architecture (SOA) became a dominant paradigm for enterprise computing. The web services are the implementation of SOA that works for heterogeneous platforms as they use common Internet protocols for communication and simple text format such as XML for data representation. The basic SOA architecture does not contain any security solution within it and the security is applie...

Current atmospheric models do not include secondary organic aerosol (SOA) production from gas-phase reactions of polycyclic aromatic hydrocarbons (PAHs). Recent studies have shown that primary emissions undergo oxidation in the gas phase, leading to SOA formation. This opens the possibility that low-volatility gas-phase precursors are a potentially large source of SOA. In this work, SOA formati...
