Computational grids provide a massive source of processing power, providing the means to support processor intensive applications. The strong burstiness and unpredictability of the available resources raise the need to make applications robust against the dynamics of grid environment. The two main techniques that are most suitable to cope with the dynamic nature of the grid are load balancing and job replication. In this work, we develop a load-balancing algorithm by juxtaposes the strong points of neighbor-based and cluster-based load-balancing methods. We then integrate the proposed load-balancing approach with fault-tolerant scheduling namely MinRC and develop a performance-driven fault-tolerant load-balancing algorithm or PD-MinRC for independent jobs. In order to improve system flexibility, reliability, and save system resource, PD-MinRC employs passive replication scheme. Our main objective is to arrive at job assignments that could achieve minimum response time, maximum resource utilization, and a well-balanced load across all the resources involved in a grid. Experiments were conducted to show the applicability of PD-MinRC. One advantage of our approach is the relatively low overhead and robust performance against resource failures and inaccuracies in performance prediction information. © 1968-2012 IEEE.

Support vector machine (SVM) is one of the state-of-the-art tools for linear and nonlinear pattern classification. One of the design issues in SVM classifier is reducing the number of support vectors without compromising the classification accuracy. A technique denoted as diminishing learning (DL) is already proposed in literature for an SVM based multi-class isolated digit recognition system using speaker dependent TI46 database of isolated digits. In this paper, the computational complexity for SVM and SVM-DL based isolated digit recognition system is studied and the computation time for both the classifiers is evaluated by system-on-programmable-chip (SOPC) implementation of the recognition system onto an Altera Cyclone II Series FPGA using Nios II Soft-core processor. The number of support vectors is reduced by 38.28-90.25 % on using SVM-DL for isolated digit recognition problem. This in turn reduces the classification time for SVM-DL by 31.45-91.78 % over SVM. Recognition accuracies of 97 and 98 % are achieved for SVM classifier with and without DL technique, respectively. The study confirms the effect of, the order in which the classes are classified, on the recognition accuracy. For the TI46 database, about 2-4 % increase in recognition accuracy is obtained by choosing the optimum order for SVM-DL classifier. The proposed SOPC implementation of SVM-DL based recognition system can be employed for various other pattern recognition applications too such as face recognition, character recognition and target recognition. © 2012 Springer-Verlag.
It's time to re-think how we get around, so this year's Biomimicry Student Design Challenge is dedicated to solving problems in our transportation system. The challenge asks students to look to nature to come up with ways to lessen the environmental impact of personal or public transportation, or to make transportation more responsive to user needs. The theme gives students a lot of room for creativity. Reducing the environmental impact of travel can mean creating fewer greenhouse gasses, lowering energy demands or cutting down on waste and pollution. Students from around the globe have already signed up, among them teams representing the Ontario College of Art and Design, the Escuela Superior de Diseno de Madrid, Bucknell University, Harvey Mudd College and the PES Institute of Technology in Bangalore. Students from the University of Calgary have participated in the Biomimicry Design challenge for the past three years. So far this year, the university has five teams registered. One of the teams is looking at how a cactus could inspire a better semi-truck. The group of six mechanical engineering students originally thought they'd model their design on a peregrine falcon. However, that proved to be a challenge. "There's so much research on birds of prey, that we really struggled to find something innovative," said Jeniece Galeano. "The cactus has proven to be promising." The team's design will also fulfill course requirements as their capstone project, and they plan to enter the University of Calgary's spring design fair. Although biomimicry is touched on in their program, team member Max Verbeurgt says there aren't currently any courses or programs focused on biomimicry. The Biomimicry Student Design Challenge aims to promote nature-inspired design solutions, but it also provides tools to students who want to learn more about biomimicry. Registering a team gives students access to a number of resources to help this process and doesn't require a complete design. The Biomimicry 3.8 Institute has hosted the challenge since 2009. The challenge is open to all students currently enrolled in a degree or certificate program, and interdisciplinary teams are strongly encouraged. Registration is open through February 7, 2014 and final designs are due April 20, 2014. Learn more about the challenge here.

Al 6063 based in situ composites were manufactured from Al-10%Ti and Al-3%B master alloys by liquid metallurgy route. The in situ TiB2 reinforced Al 6063 composites were synthesized through the exothermic reaction between Al-10%Ti and Al-3%B master alloys, which were used in the ratio of 1:2 respectively in Al 6063 matrix alloy. Tribological properties of both Al 6063 matrix alloy and the developed in situ composites have been evaluated. Dry sliding friction and wear tests were carried out using a pin on disc type machine with steel counter disc hardened to HRC60. A load range of 10-50N with the sliding velocity varying from 0.209m/s to 1.256m/s were adopted. Results have revealed that the developed in situ composites have lowered coefficient of friction and wear rates when compared with Al 6063 matrix alloy under all the test conditions studied. The excellent wear resistance of the in situ composites results from the formation of fine TiB2 particles uniformly dispersed within the Al 6063 matrix alloy. The coefficient of friction of both matrix alloy and in situ composites decreased with increase in load, whereas it increased with increase in sliding velocity. However, wear rates of both matrix alloy and in situ composites increased with increase in both load and sliding velocity. © 2011 Elsevier B.V.

Purpose – The purpose of this paper is to examine the success of enterprise resource planning (ERP) implementation based on five identified items, i.e. top management commitment (TMC), user involvement (UI), business process reengineering (BPR), project management (PM) and ERP teamwork and composition (TWC) factors at Fortis hospital, Bangalore, India. It also tests a number of hypotheses and examines the hypothetical relationships among critical success items and success of ERP implementation. Design/methodology/approach – Empirical data were collected via a survey questionnaire/interview technique. A structured interview was planned and conducted with key executives of Fortis hospital who were familiar with success of ERP implementation progress as well as examination of company documentation supported by literature. Findings – A significant relationship was found between TMC, UI, BPR, PM and ERP TWC with success of ERP implementation at Fortis hospital. Originality/value – The value of this paper is that it presents any hospital wishing to implement ERP with a set of critical success factors. Understanding the critical success factors would lead to a smoother implementation in hospital industry.Although as a single case study the ability to generalize the findings is narrow, support from literature and experiences add the knowledge to ERP implementation in healthcare sector in India. © Emerald Group Publishing Limited.
