The fast growing rate of the usage of large-scale computing machines on cloud platform has resulted in increased consumption of energy and emission of carbon. Such negative effects should be curbed for a more environmental-friendly computing platform, e.g. a green cloud computing platform. Scheduling is one of the aspects that can be looked into in regards to the improvement of the whole cloud architecture, specifically in the scope of resource management. One of the important features that need to be optimized in regards to scheduling is the load balancing process that emphasizes on optimal resource utilization, maximum throughput, maximum response time and prevention of overload. One way to optimize the load balancing process is by implementing the migration of virtual machines across multiple hosts, in which utilization of CPU resources can be optimized. The appropriate use of two different classes of resources e.g. low-powered and high-powered machines based on their Million Instructions Per Second (MIPS) metrics, will lead to minimal process execution time if both types of resources are being efficiently used and effectively mapped to suitable types of processing. According to different machine performance, the migration of virtual machines will be computed based on the current CPU utilization following three different conditions, i.e. when the CPU usage reaches its 90%, 10% and 0% marker. Based on this idea, a general algorithm in activating the virtual machine migration is proposed, in which the overall load balancing process could be improved.","PeriodicalId":160566,"journal":{"name":"2014 5th International Conference on Intelligent and Advanced Systems (ICIAS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125296024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As computational modeling needs vast of simulation time, a real-time hardware implementation using FPGA could be the solution as it provides high configurability and performance. For rapid prototyping, MATLAB Simulink that offers a link with the FPGA has been used. Through Simulink HDL Coder, a tool in the MATLAB software that capable to convert the MATLAB Simulink blocks into hardware description language (HDL) code and an FPGA-in-the-loop (FIL) and co-simulation for verification, FPGA hardware implementation can be done. As a result, the LR-I excitation model is successfully simulated by using the MATLAB Simulink and the VHDL code has been successfully generated by the HDL Coder after fixed-point optimization is done. The FIL verification on actual FPGA board also has shown quantitatively comparable results to the MATLAB Simulink simulation. Therefore, the design flow has given a positive outlook in developing this FPGA stand-alone implementation.","PeriodicalId":160566,"journal":{"name":"2014 5th International Conference on Intelligent and Advanced Systems (ICIAS)","volume":"549 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127666455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ultrasound is continuously promoted by physicians and radiologist because of its features such as use of non-ionizing radiations, non-invasive nature, real time diagnosis, portability, over existing imaging modalities such as Magnetic resonance imaging (MRI) and Computed tomography (CT). Despite many advantages, images obtained from ultrasound equipment suffer from loss of resolution and contrast. In this paper, contrast enhancement of ultrasound image is performed using adaptive statistical method and comparison with original ultrasound image was performed. The quantitative analysis was performed based on three different measurement indices. The measurement indices used to evaluate the performance of contrast enhancement images are universal quality index (UQI), structural similarity index (SSI) and signal to noise ratio (SNR). The ultrasound enhanced and original images are shown for visual references. The quantitative comparison suggests gamma correction to perform best among the chosen methods. The analysis was performed based on real dataset collected from University Malaya Medical Center on patients suffering from MSK disorder in shoulder. Total of 37 images from 23 patients were evaluated to verify the study. Later, several dataset from patients will be collected and qualitative assessment of images will be performed to validate the study for all images.","PeriodicalId":160566,"journal":{"name":"2014 5th International Conference on Intelligent and Advanced Systems (ICIAS)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133617359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
