GREEN CLOUD COMPUTING: GREEN INDEXING OF CLOUD NETWORK RESOURCES

The present-day methods of green cloud computing are focused principally on data processing and data storage. However, the transmission and switching elements are often not considered in green cloud computing. Techniques are presented herein that support a mathematical model which focuses on the end-to-end cloud environment including, for example, transmission, switching, data storage, and data processing elements. In particular, energy efficiency, a minimal carbon footprint, optimal capital expenditures, and the fewest operating expenditures are the need of hour for both middle-scale and massive-scale cloud environments and data centers. The presented techniques encompass a mathematical model along with elaborating use cases to successfully meet all the objectives noted above

Effects of Thickness and Indenter Tip Geometry in Nanoindentation of Nickel Films

Nanoindentation has become a widely used technique to measure the mechanical properties of materials. Due to its capability to deform materials in micro- and nano-scale, nanoindentation has found more applications in characterizing the deformation behavior and determining the mechanical properties of thin films and coatings. This research deals with the characterization of samples received from Center for Advanced Microstructures and Devices (CAMD) and Integran Technologies Inc., Toronto, Canada and the objective of this investigation was to utilize the experimental data obtained from nanoindentation to determine the deformation behavior, mechanical properties of thin films on substrates and bulk materials, and the effect of geometrically different indenters (Berkovich, cubecorner, and conical). X-ray diffraction (XRD), transmission electron microscope (TEM), scanning electron microscopy (SEM), and atomic force microscopy (AFM) analysis were performed on these materials to determine the crystal orientation, grain size of the material, and also to measure any substrate effects like pile-up or sin-in respectively. The results indicate that indentation size effect (ISE) strongly depends on shape of the indenter and less sensitive to penetration depth where as the hardness measurements depends on shape of indenter and depth of penetration. There is a negligible strain rate dependency of hardness at deeper depths and a significant increase in the hardness due to the decrease in grain size and results also indicate that there is no significant substrate effect on thin films for 10% and 20% of film thicknesses. Nanocrystalline material could not validate a dislocation based mechanisms deformation for indentation made by cubecorner and conical indenters in depths less than 1mm

A cognitive approach to decision support systems

 A Decision Support System is not merely a computer -based information system designed to collect, manipulate and generate information. It is a tool which enhances the decision making capabilities of managers by augmenting their mental processes. It is often difficult for the user to adapt any information system into the decision making process if the decision maker is psychologically unsatisfied about the capabilities or performance of that system. Strategies for design of DSS should focus on design, development and implementation of systems which are highly interactive with the users and assimilate into their decision process. The research is exploratory in nature. Initially in this research, the human decision making processes is analysed and two models on human decision making are identified after synthesising past studies. A set of desirable cognitive attributes is derived from a comprehensive literature review. The cognitive attributes summarised into a checklist and the checklist is then applied to the evaluation of selected DSS packages. The evaluation indicates that the current available literature can provide operational guidelines for cognitive considerations in the design of DSS. The research further explains that design considerations arising from the set of desirable attributes may eventually enhance the quality of Human Computer Interaction. Limitations and future research opportunities are discussed.  </p
