Storage-area networks are a popular and efficient way of building large storage systems both in an enterprise environment and for multi-domain storage service providers. In both environments the network and the storage has to be configured to ensure that the data is maintained securely and can be delivered efficiently. In this paper, we describe a model of mandatory security for SAN services th...

Ubiquitous computing software needs to be autonomous so that essential decisions such as how to configure its particular execution are self-determined. Moreover, data mining serves an important role for ubiquitous computing by providing intelligence to several types of ubiquitous computing applications. Thus, automating ubiquitous data mining is also crucial. We focus on the problem of automati...

This paper presents Ingrid, an architecture for a fully distributed, fully self-configuring information navigation infrastructure that is designed to scale to global proportions. Unlike current designs, Ingrid is not a hierarchy of large index servers. Rather, links are automatically placed between individual resources based on their topic similarity in such a way that clusters of term combinat...

Today's communication-based applications are mostly crafted in a stovepipe development paradigm, which is inflexible to be used by various domain-specific applications and costly in the development phase. In a previous paper [1], we proposed a new design called CVM (Communication Virtual Machine) to overcome these problems by having a high-level API which can be reused and extended easily for u...

Global supply chains and worldwide spread subsidiaries are a topic for both huge enterprises as well as for small and medium sized enterprises. The challenge lies in the right allocation of functions and competencies within the global production network and in their coordination and integration in order to gain the desired outcome and to reach the objectives tied to the networks. In this contex...

This paper describes Livingstone, an implemented kernel for a model-based reactive self-configuring autonomous system. It presents a formal characterization of Livingstone’s representation formalism, and reports on our experience with the implementation in a variety of domains. Livingstone provides a reactive system that performs significant deduction in the sense/response loop by drawing on ou...

Most of today's generic annotation tools for semantic web metadata (RDF) are designed for experts. People with no or little knowledge about RDF are therefore forced to use simplified and often domain-specific tools that work with fixed sets of metadata elements. This paper introduces the Annotation Profile Model as a configuration mechanism from which annotation tools can be automatically gener...

This paper describes a racing procedure for finding, in a limited amount of time, a configuration of a metaheuristic that performs as good as possible on a given instance class of a combinatorial optimization problem. Taking inspiration from methods proposed in the machine learning literature for model selection through cross-validation, we propose a procedure that empirically evaluates a set o...

Academia has a long tradition of structuring itself around academic subjects, often epitomized through architectural manifestations such as individual buildings and whole campi. These materializations serve as sites of research and education, but also serve to describe the university as whole as well as its institutional parts, their definitions and their interrelations. This description goes d...

The main objectives of SaaS application are to make the management and control of software easier and take the management strain away from consumers. However, it also leads to software services available globally and this has been realized in our paper by designing a new model for SaaS application. The three levels we have classified in our model easy adapted to workflow and services. From the ...
