Business Level Service-Oriented Enterprise Application Integration

In this paper we propose a new approach for service-oriented enterprise application integration (EAI). Unlike current EAI solutions, which mainly focus on technological aspects, our approach allows business domain experts to get more involved in the integration process. First, we provide a technique for modeling application services at a sufficiently high level of abstraction for business experts to work with. Next, these business experts can model the orchestration as well as the information mappings that are required to achieve their integration goals. Our mediation framework then takes over and realizes the integration solution by transforming these models to existing service orchestration technology

Semantic Service Modeling: Enabling System Interoperability.

Interoperability is the capability of different systems to use each other’s services effectively. It is about sharing functionality and information between systems at different levels, e.g., between physical devices, software applications, business units within one organization, or between different organizations. Interoperability implies that systems are able to interact (i.e., exchange messages), read and understand each other’s messages, and share the same expectations about the effect of the message exchange. In this paper we analyze and define in detail what it means for software systems to be interoperable. We identify three different levels of interoperability – the syntactic, semantic and pragmatic level – and define the requirements for assessing interoperability at each of these levels. We propose a method for formally verifying the semantic and pragmatic interoperability of a number of systems, given a target for integration

Requirements and Method for Assessment of Service Interoperability

Service interoperability is a major obstacle in realizing the SOA vision. Interoperability is the capability of multiple, autonomous and heterogeneous systems to use each other’s services effectively. It is about the meaningful sharing of functionality and information that leads to the achievement of a common goal. In this paper we systematically explain what interoperability means and analyze possible interoperability problems. Further, we define requirements for service interoperability and present a method to assess whether a composite system meets the identified requirements

The impact of weathering and aging on a LIMB ash stockpile material

A 1,500 ton temporary storage pile of water conditioned LIMB (Lime Injected Multistage Burner) ash by-product from the Ohio Edison Edgewater plant Lorain, OH was constructed in July, 1991 at a coal company near New Philadelphia, Ohio. This stockpile was created for dry FGD by-product material to be held in reserve for a land application uses field demonstration. High volume, beneficial uses of dry FGD by-products, such as for mine reclamation and embankment stabilization, will require temporary stockpiling of the by-product. Purpose for constructing this pile was to study changes with time in the LIMB by-product material when exposed to weathering. This by-product material was studied over a 2 1/2 year period. The water to control fugitive dust was added in the ash conditioner at the power plant while being loaded into dump trucks. Amount of water normally added in the conditioning process is close to the optimum moisture content of 40--50 % (dry weight basis), to construct a compacted road embankment or road base. Four environmental operating permits required for construction of the storage pile were obtained, three from Ohio EPA (air, water and solid waste), and one from the Ohio Division of Reclamation (revised reclamation area permit). There was no significant environmental impacts from storm runoff or leachate water from the LIMB ash stockpile during the initial 18 month period through December, 1992. After 2 1/2 years of storage, the potential value of the LIMB material for use as a road embankment material or soil conditioner has declined significantly. Ettringite formation occurs. Aging allows the expansive reaction to take place before its potential use as compacted structural fill or embankment

Oscillation enhanced search for new interaction with neutrinos

We discuss the measurement of new physics in long baseline neutrino oscillation experiments. Through the neutrino oscillation, the probability to detect the new physics effects such as flavor violation is enhanced by the interference with the weak interaction. We carefully explain the situations that the interference can take place. Assuming a neutrino factory and an upgraded conventional beam, we estimate the feasibility to observe new physics numerically and point out that we can search new interactions using some channels, for example $\nu_{\mu} \to \nu_{\mu}$, in these experiments. We also discuss several models which induce the effective interactions interfering with the weak interaction, and show that some new physics effects are large enough to be observed in the oscillation enhanced way.Comment: 25 pages, 20 figure
