L. Walker This paper discusses the use of service-oriented architecture (SOA) as one of the key elements supporting business transformation at IBM. It describes the internal SOA strategy, SOA governance, organizational impacts, and several IBM internal SOA case studies. The top-down and bottom-up approaches to promoting SOA within the enterprise are also illustrated, along with a set of SOA bus...

Field measurements of secondary organic aerosol (SOA) find significantly higher mass loads than predicted by models, sparking intense effort focused on finding additional SOA sources but leaving the fundamental assumptions used by models unchallenged. Current air-quality models use absorptive partitioning theory assuming SOA particles are liquid droplets, forming instantaneous reversible equili...

Recently, Service-Oriented Architecture (SOA) has received significant attention. SOA simulation can play an important role in SOA software development as it can be used to verify the SOA application models and to demonstrate runtime and collaborative behaviors of the SOA applications. SOA simulation differs from traditional simulation as it emphasizes on reusability, collaborative behaviors, a...

In this paper first we try to analysis the behavior ofthe SOAs in the optical networks and then have proposed anumerical simple model to simulate the behavior of thesemiconductor optical amplifiers. After that by employing thismodel as inline amplifier for a DWDM optical system, we havesimulated the transmission of 10 channels with bit rate 10 Gb/sup to distance 3970 km with RZ-DPSK modulation ...

To support the difficult process of SOA adoption, SOA maturity models are published. In this thesis a literature analysis introduces the area of SOA maturity models and highlights benefits and criticism. As a result, the combined SOA maturity model (CSOAMM), a model to facilitate the interpretation and comparison of SOA maturity models, is proposed. CSOAMM is a model with 10 levels that describ...

There is a general consensus that SOA benefits could be reached but it is unclear how to achieve this. Research shows that the problems with SOA governance in practice are among the major reasons of SOA failures. Based on a literature review, this study first proposes a list of SOA aspects to be considered when implementing SOA governance. By adopting an interpretive research methodology based ...

The paper reports secondary organic aerosol (SOA) yield, mass absorption coefficient (MAC) values, and light-absorbing compounds in SOA produced from photooxidation of indole. High SOA yield was observed and several compounds (i.e. -heterocyclics) were found to absorb visible light. Additionally, an air quality simulation was used to evaluate the contribution of indole-SOA to total atmospheric ...

Service oriented architectures (SOA) are becoming reality in a corporate environment. Rather than pure technology improvements SOA intends to increase manageability and sustainability of IT systems and to better align business requirements and technology implementations. Following these intentions current SOA research is focused on the management of SOA. In this paper we present a method to ide...

Due to their economic and technological benefits, Service Oriented Architectures (SOA) are valued more and more by companies in all industries and sizes. This paper explains SOA briefly and presents approaches for migrating to an SOA in ‘real life’. We will discuss how SOA design methods and proven software reengineering technology can be combined in order to support a company’s SOA adoption ro...

Das Thema SOA begleitet uns nun schon seit einigen Jahren und immer wieder wird uns die Frage gestellt „Können Sie als Requirements Engineer auch mit SOA umgehen?“ Interessant wird es, wenn wir diese Frage mit einer Gegenfrage beantworten „Was bedeutet denn für Sie SOA?“. Vielleicht wird es Sie als Leser nicht verwundern, dass wir bisher immer eine andere Definition von SOA erhielten. In den me...
