Ground rubber powder (GRP) is a waste material obtained from discarded tires and has been explored as a reinforcement material in polyethylene (PE) composites to improve their mechanical properties. The present study investigates the influence of GRP content and particle size on the properties of PE/GRP composites. The samples were characterized using Scanning Electron Microscopy (SEM) for surface morphology, Fourier Transform Infrared Spectroscopy (FTIR) for identifying organic compounds, and several mechanical tests to evaluate the properties. Statistical analysis was conducted through a one-way analysis of variance (ANOVA) to assess the impact of different GRP concentrations on the impact strength within each particle size range. Based on the SEM analysis, the surface of PE exhibits a smooth and homogeneous texture, while the SEM image of the PE/GRP blend reveals a strong interfacial bonding and compatible morphology between the two components. The spectrum of the GRP revealed characteristic vibrations associated with polyisoprene, a major component of tire rubber. In the case of polyethylene PE, bands related to the characteristic vibrations of C-H groups were observed, along with indications of polyethylene degradation through oxidation. These findings contribute to the understanding of the chemical composition and properties of the individual components in the PE/GRP blend. In terms of mechanical properties, the elongation at break (EB) results showed that higher GRP concentrations, particularly at 10%, led to improved elongation values, indicating the reinforcing effect of GRP particles on the PE matrix. The impact strength analysis revealed that the inclusion of GRP particles significantly enhanced the impact strength of the blend. The optimal GRP concentration for maximizing impact strength was found to be 10%. Moreover, statistical analysis through a one-way analysis of variance (ANOVA) indicated that the impact strength variations were significantly influ

Service composition is among the most important challenges that cloud providers have ever faced. Optimization of QoS attributes when composing simple atomic services to obtain a complex service can be considered to be an NP-hard problem, which could be solved properly by using Hybrid optimization algorithms. In this research, the hybridization of an improved Gravitational Attraction Search (as a local search algorithm) with an Imperialist Competitive Algorithm has led us to introduce and apply a new memetic algorithm for gaining optimal or near optimal response time and execution fees simultaneously, for cloud computing service composition. Using a roulette wheel selection algorithm to make well-advised and non-blind decisions to choose the number of countries in each empire that should be selected to apply a local search to has assisted the hybrid algorithm at achieving better solutions. Introducing a new equation to calculate the QoS eligibility of the solutions that were generated based on the normalization of the response time and execution fee has also led us to compute the results fairly and in a scientifically based manner.

Complexity reduction approach has been used to solve various science and technology problems. In this paper we will discuss the implementation of the approach to solve some hyperbolic equation such as first order hyperbolic problem and the Maxwell Equations. For solving the Maxwell equations, we implement a weighted average fourth order truncation with the complexity reduction approach. The approach shown to successfully reduce the complexity of original method. Results show to increase the speed up of its original method significantly.

PCs in computing labs at institution of higher learning are often if not always underutilized. These PCs are usually not used at night and early morning (i.e. between 10pm-8am), during semester breaks, weekends and during final examinations. At other times most of the lab PCs are not utilized up to the available capacity. This underutilization scenario provides an excellent opportunity for researchers to utilize these lab PCs for research work that requires immense computing power. Furthermore, it is noteworthy that the life cycle of a PC is about 5 years which comes to about 1826 days (1 year = 365.25 days). At the end of its life cycle, new PCs are often purchased to replace the older ones. Thus, using these PCs effectively before being rendered obsolete should be given high priority. The use of distributed computing for compute intensive problems is not new. However, with the availability of improved hardware, fast interconnects and user friendly middleware, the use of distributed computing has become even more popular now. In this paper, we discuss our experience in using Condor middleware on lab PCs at Faculty of Information Science and Technology. We have recorded good speedups from our experiments for embarrassingly parallel problem that we executed on the lab PCs. A script and programs were written to automate the process of preparing input files, merging output files, and displaying output. The single command execution provided by the script offers user friendly environment for the users. We hope the outcome of this experiment will encourage more faculty members to use the available resources at the computing labs for their research work. © 2011 IEEE.

The Open-H2O community is developing ocean technology with the aim of co-designing the technology; licensing under the Open Source Software and Hardware protocols; and gathering ocean data from its different technology users and developers. Protei is a fleet of autonomous, shape-shifting, sailing vessels for ocean exploration and conservation, created by the Open-H2O community. This paper presents the tools and learning environments used during the development of Protei, and the opportunities created in terms of education and engagement of the Public, Scientific and industrial sectors. Three case studies are presented, concluding with the challenges and education perspectives lying in the growth of the Open-H2O community.

Computational clusters have become a dominant platform for a wide range of applications in scientific disciplines, engineering and commerce. This is due to their low cost, high performance, availability of off-the-shelf hardware components and freely accessible software tools that can be used for developing cluster applications. To manage, monitor and administer all the nodes in a cluster environment, a specific system known as Cluster Control System (CCS) is required. Even though there are numerous systems available, most of it are developed specifically for in-house use such as scientific research or commercial purpose. In this paper, we discuss a prototype and architecture of UKM Cluster Control and Management (UKM C2M) system that we developed using open source software. The UKM C2M has six modules namely a switch manager, program manager, report manager, user manager and administrator manager. This module allows an administrator to manage, monitor and administrate all the nodes in the cluster concurrently and effectively. The main purpose of developing UKM C2M is to provide a lightweight system for managing clusters effectively. In this work, we included a report manager that is not available in many CCS to keep track, collect and generate node information continuously for later retrieval. These information can be archived in secondary storage or printed as a hardcopy. The overall design of UKM C2M is described and the details on each of the six modules is presented in this paper. © 2011 IEEE.

Our previous researches have shown the extraordinary performance of quarter sweep iteration to speed-up the original method by four times. In this paper, an experimental study is conducted to show the efficiency of the red-black quarter-sweep iteration by using the Crank-Nicolson (CN) finite difference approximation scheme to obtain numerical solutions of the first order hyperbolic equation. In this paper, the implementation of the red-black strategy to full-sweep Gauss-Seidel (FGS-RB), half-sweep Gauss-Seidel (HGS-RB), and the quarter-sweep Gauss-Seidel (QGS-RB) methods will be discussed. Finally, through numerical results obtained, the QGS-RB iterative method has been shown to be the most superior method compared to FGS-RB and HGS-RB methods.
