This paper describes a generic framework facilitating the specification and construction of component-based distributed systems. The framework integrates methods for specification of systems with tools supporting the construction of those systems. This is achieved by defining a reference architecture supported by a metamodel, a Component Modelling Language and tools for code-generation. The met...

An extension of earlier work on component compatibility is described in this paper. Similarly as before, the behavior of components is specified by component interface languages, and the shuffle operation is introduced to represent possible interleavings of service requests that originate at several concurrent components. The paper shows that the verification of component compatibility is possi...

One of the many difficulties in making Component-Based Software Engineering (CBSE) a reality is the adaptation of software components that may be required when constructing applications from COTS components. We surveyed the literature to discover various approaches to component adaptation and evaluated these approaches against a set of requirements for component adaptation mechanisms. We also d...

This paper proposes an extension to scalar component methodology for the identification and estimation of VARMA models. The complete methodology determines the exact positions of all free parameters in any VARMA model with a predetermined embedded scalar component structure. This leads to an exactly identified system of equations that is estimated using full information maximum likelihood.

This study was conducted to evaluate some development factors in Southern Nigeria order ascertain common that explained the interrelationships among them and identify best cities for recommendation. A total sample of 250 from different states three geopolitical zones used this 11 were considered. Kaiser-Meyer-Olkin (KMO) (> 0.5) computed test sampling adequacy; Bartlett’s Test Sphericity (Si...

This paper constitutes an extension to the report on DISAMU team participation in the ImageCLEF 2014 Scalable Concept Image Annotation Task as published in [3]. Specifically, we introduce a new similarity search component that was implemented into the system, report on the results achieved by utilizing this component, and analyze the influence of different similarity search parameters on the an...
