User involvement in the system design process and the final success of a system has been the subject of many studies. Conflicting results reported in those studies have not helped to resolve the issue. This study employs meta-analysis to systematically combine the results of many user involvement studies to see if the overall results are significant. In addition, the strength of the relationshi...

In this project, we propose a malaria model which takes into account the climate factors, the extrinsic incubation period (EIP) and the vector-bias effect. We first obtain the basic reproduction ratio R0 and then prove that it serves as a threshold parameter in determining the global dynamics of the model, that is, the disease-free periodic solution is globally attractive if R0 is less than one...

Nowadays, internet has changed the world into a global village. Social Media has reduced the gaps among the individuals. Previously communication was a time consuming and expensive task between the people. Social Media has earned fame because it is a cheaper and faster communication provider. Besides, social media has allowed us to reduce the gaps of physical distance, it also generates and pre...

This research-in-progress paper presents a new approach called Link Proximity Analysis (LPA) for identifying related web pages based on link analysis. In contrast to current techniques, which ignore intra-page link analysis, the one put forth here examines the relative positioning of links to each other within websites. The approach uses the fact that a clear correlation between the proximity o...

Structural analysis of supply chains often involves postponement to some degree. The concept has received a lot of attention in the literature but the understanding of how to operationalize the concept still deserves some attention. A framework is introduced that provides an integrative picture of how different aspects of supply chain and operations management interplay in a postponement contex...

A method for the identification of small inhomogeneities from a surface data is presented in the framework of an inverse scattering problem for the Helmholtz equation. Using the assumptions of smallness of the scatterers one reduces this inverse problem to an identification of the positions of the small scatterers. These positions are found by a global minimization search. Such a search is impl...

The relationship between machining speed and the process mean for a manufacturing process has received little attention. This paper presents an analytical model and its solution procedure to simultaneously determine the optimal machining speed and process mean when the objective is to minimize the total cost per part. The total cost of the model includes replacement (resetting), production and ...
