Much of the existing work in component-based software technology has concentrated on developing infrastructure capabilities and middleware solutions for connecting independent pieces of system functionality. The result of this work is a range of maturing infrastructure products for supporting deployment of distributed systems. Examples include message-oriented middleware (MOM) products such as ...

In this tutorial, attendees will learn how to architect safely extensible component systems. The tutorial introduces to the concepts of component-oriented programming before presenting and explaining compound documents as an application example of extensible component systems. Creation of an add-on component to this system will be demonstrated. Finally, architecting for safe extension will be d...

Component-based software development is becoming more generalized, representing a considerable market for the software industry. The perspective of reduced development costs and shorter life cycles acts as a motivation for this expansion. However, several technical issues remain unsolved before software component’s industry reaches the maturity exhibited by other component industries. Problems ...

the divisibility graph $mathscr{d}(g)$ for a finite group $g$ is a graph with vertex set ${rm cs}(g)setminus{1}$‎ ‎where ${rm cs}(g)$ is the set of conjugacy class sizes of $g$‎. ‎two vertices $a$ and $b$ are adjacent whenever $a$ divides‎ ‎$b$ or $b$ divides $a$‎. ‎in this paper we will find the number of connected components of $mathscr{d}(g)$ where $g$ is a‎ ‎simple zassenhaus group or an sp...

detecting anomalies is an important challenge for intrusion detection and fault diagnosis in wireless sensor networks (wsns). to address the problem of outlier detection in wireless sensor networks, in this paper we present a pca-based centralized approach and a dpca-based distributed energy-efficient approach for detecting outliers in sensed data in a wsn. the outliers in sensed data can be ca...

background: we examined epidemiological aspects of dynamic changes in incidence of ovarian cancer in women of kazakh and russian nationalities in kazakhstan. methods: the material of investigation was primary data on registered patients with malignant ovarian tumors in the whole country. the study was conducted during the period of 1999-2009. evaluation of changes in ovarian cancer incidence in...

linseed is an important oilseed and fibre crop predominantly grown in india. the aim of the present research was to evaluate genetic diversity and patterns of relationships among the 58 genotypes through 10 morphological traits and 12 polymorphic microsatellite (ssr) markers. euclidean analysis of agro-morphological traits grouped the 58 genotypes into four clusters of which cluster i was the l...

Component selection is not an easy task in Component Based Software Engineering .and it is very difficult to select component for CBSE. Component Based Software Engineering (CBSE) is a concerned with the assembly of pre-existing software components that leads to a software system that responds to client-specific requirements. This paper presents an approach for defining evaluation criteria for ...

Fractal is a component model developed initially by France Telecom and INRIA and later as an open source project in the ObjectWeb consortium. The component model is defined by the Fractal Component Model specification [BCS]. The specification defines a hierarchical component model, where a component is specified in terms of its server and client (provided and required) interfaces and configurab...
