The 24Hour Knowledge Factory is a software development paradigm that goes beyond the conventional global delivery model. It involves round-the-clock operations through the establishment of three or more development teams around the globe. Complex projects are iteratively broken down into simpler modules, with a “composite persona” (CP) being responsible for each of such modules. Developers arou...

The European Food Safety Authority (EFSA) received a request on 19 September 2008 from the European Commission, Health and Consumers Directorate requesting urgent scientific advice on the risks to human health due to the possible presence of melamine in composite food products imported from China into the European Union (EU). Considering the urgency of this request for advice EFSA issued a stat...

The breakthrough in biomedical and surgical instrument research follows the advances of newly developed biomedical technologies, improved composite materials, and renovated manufacturing methodologies. These new biomedical and surgical instruments allow physician to perform complex biomedical treatments and surgical operations with better medical quality. Some more complicated biomedical treatm...

This paper re-evaluates the security of a chaotic image encryption algorithm called 13 MCKBA/HCKBA and finds that it can be broken efficiently with two known plain-images and 14 the corresponding cipher-images. In addition, it is reported that a previously proposed breaking 15 on MCKBA/HCKBA can be further improved by reducing the number of chosen plain-images 16 to two from four. The two attac...

This work comprises several projects that involve optimization of physical systems. By a physical system we understand an object or a process that is governed by physical, mechanical, chemical, biological, etc., laws. Such objects and the related optimization problems are relatively rarely considered in operations research literature, where the traditional subjects of optimization methods are r...

Use of Non Destructive Testing (NDT) technique during aircraft maintenance operations is increasing in the last years as well as the tools to perform these inspections are widening their field of application. Damage tolerance design approach has been selected by aeronautic industry for the last years also thanking to the most modern NDT capabilities, like ultrasound and thermography, which have...

The utilization of TiB2 particles reinforced aluminum (Al6063) metal matrix composite materials in many different engineering fields has undergone a tremendous increase. Accordingly, the need of accurate machining of composites has increased enormously; an attempt has been made to assess the factors influencing surface roughness and material removal rate on machining the composite. The orthogon...

t he purpose of this study was to examine farm operations cooperation groups in central agricultural zone of delta state, nigeria. all the members of the six  selected groups were used for the study. the data which were collected with the use of questionnaire and interview schedule were analyzed with the use of frequency counts, percentages and tobit regression model. most of the members were ...

Portability and automated management of composite applications are major concerns of today’s enterprise IT. These applications typically consist of heterogeneous distributed components combined to provide the application’s functionality. This architectural style challenges the operation and management of the application as a whole and requires new concepts for deployment, configuration, operati...

Web Services are interfaces that describe a collection of operations that are network-accessible through standardized web protocols. When a required operation is not found, several services can be compounded to get a composite service that performs the desired task. To find this composite service a search process in a, generally, huge search space must be performed. The algorithm that composes ...
