The development of code for finite elements-based field computation has been going on at a pace since the 1970s, yielding code that was not put through the software lifecycle - where code is developed through a sequential process of requirements elicitation from the user/client to design, analysis, implementation and testing (with loops going back from the second stage onwards as dissatisfactions are identified or questions arise) and release and maintenance. As a result, today we have legacy code running into millions of lines, implemented without planning and not using proper state-of-the-art software design tools. It is necessary to redo this code to exploit object oriented facilities and make corrections or run on the web with Java. Object oriented code's principal advantage is reusability. It is ideal for describing autonomous agents so that values inside a method are private unless otherwise so provided - that is encapsulation makes programming neat and less error-prone in unexpected situations. Recent advances in software make such reverse engineering/reengineering of this code into object oriented form possible. The purpose of this paper is to show how existing finite element code can be reverse/re-engineered to improve it. Taking sections of working finite element code, especially matrix computation for equation solution as examples, we put it through reverse engineering to arrive at the effective UML design by which development was done and then translate it to Java. This then is the starting point for analyzing the design and improving it without having to throw away any of the old code.

Small and Medium Industries (SMIs) generate significant contribution in the economic growth in developing countries. To achieve the standard expected product from customers, SMIs must produce marketable product in term of quality, quantity and prices. This requires the investment in technology for supporting daily operation and maintenance management. In previous research, maintenance decision support system has been developed using decision making grid (DMG) model to solve the problem. In this study, the researches apply tri-quadrant technique to cluster the DMG. This study focuses on the effect from the improvement of DMG model in categorizing low, medium and high criterion for the real production floor in SMIs. The result shows not only the reduction of cost and machines downtime but also better reliability on daily maintenance operation.

In the analysis of medical images for computer-aided diagnosis and therapy, segmentation is often required as a preliminary step. Medical image segmentation is a complex and challenging task due to the complex nature of the images. The brain has a particularly complicated structure and its precise segmentation is very important for detecting tumors, edema, and necrotic tissues in order to prescribe appropriate therapy. Magnetic Resonance Imaging is an important diagnostic imaging technique utilized for early detection of abnormal changes in tissues and organs. It possesses good contrast resolution for different tissues and is, thus, preferred over Computerized Tomography for brain study. Therefore, the majority of research in medical image segmentation concerns MR images. As the core juncture of this research a set of MR images have been segmented using standard image segmentation techniques to isolate a brain tumor from the other regions of the brain. Subsequently the resultant images from the different segmentation techniques were compared with each other and analyzed by professional radiologists to find the segmentation technique which is the most accurate. Experimental results show that the Otsu's thresholding method is the most suitable image segmentation method to segment a brain tumor from a Magnetic Resonance Image.

Supply chain management involves planning and management of suppliers and retailers that are engaged in a business process. These entities operate in a distributed and interconnected complex world that manifests in ever-changing dynamic systems with lots of uncertainty. Those systems cannot be modeled by traditional techniques that assume the stability of a system during execution. In addressing the above issue, we have postulated a multi agent system to emulate process in supply chain management. The system is able to create multiple Agents upon the dynamic requests and enables passing messages to establish negotiations among agents to achieve the best deals to satisfy requirements of both suppliers and the retailers. The agents execute successfully or they could not compete, kill themselves and come up with better strategies again only when necessary, thereby saving the computing resources to execute the agent system. The system has been tested for various possible cases and found to be successful for modeling the complex domain of supply chain management.

The main objective of this study is to design and implement a suitable algorithm and its simulation for vehicle detection to control road traffic. The system developed is able to detect moving metal objects (vehicles) and then to calculate the appropriate duration for the traffic signals at an intersection to operate. By employing mathematical functions to calculate the appropriate timing for the green signal to illuminate, the system can help to solve the problem of traffic congestion. The sensing element used to detect vehicles was a Magneto-Resistive sensor. The simulation of the algorithm of the traffic signal system was done using software. First stage of the hardware simulation tests were successfully performed on the algorithm implemented into a controller. Using the Graphical User Interface (GUI) developed, the operation of the traffic lights according to the new, calculated time can be observed. The new timing scheme that was implemented promises an improvement in the current traffic light system in terms of time save and track utilization and this system is feasible, affordable and more than that it is ready to be implemented with minimum changes to the current traffic system in Sri Lanka.

A web enabled visualization methodology is proposed in this work for viewing time varying spatial data. The technique is simple, and hence could be used by non experts of IT or GIS. The user can upload own datasets prepared in a given format with specific fields. The variation of time for data visualization can be adjusted. A web server and centralized GIS engine would process the data and the visualization would be sent to the web client as an animation. Spatial and temporal interpolation is used at the server side. In order to test the methodology, a GIS based Time-varying Spatial Information Visualizer is developed. The methodology is tested with local weather data. It can be used for visualization of demographic data as well. The methodology can be further developed to add forecasting facilities based on user provided data.

Cadaver dissection is a valuable tool in anatomy teaching for medical students. With practical constraints that anatomy teachers face today, they seek to improve the quality of teaching using computer aided novel teaching methods. In this paper, we propose a cadaver dissection simulator based on the digital anatomical images of Visible Human Project dataset. The simulator would be used as a pre-lab tool to get familiar with the dissection process. Students are able to interact with the tool and define an organ or an area of a region to be removed. By defining and removing each successive organ/region, dissection could be carried out as it is being done in the laboratory. The original true colour is preserved in the rendered volume to impart a real life experience. In developing the simulator, the original digital images were pre-processed by “The Visible Human Preprocessing Toolkit” plug-in of ImageJ. Further processing was done through the Visualization Toolkit (VTK) to remove unnecessary patches that remained in the background. Segmentation of the preprocessed images was carried out by the “LiveWire” plug-in in ImageJ. Finally, true colour visualization was carried out through VTK. We successfully demonstrated the simulator for dissection in the abdomen region.
尸体解剖是医学生解剖教学的重要手段。面对当今解剖学教师所面临的实际限制，他们寻求利用计算机辅助的新颖教学方法来提高教学质量。在本文中，我们提出了一个基于可视化人体计划数据集的数字解剖图像的尸体解剖模拟器。该模拟器将用作实验室前的工具，以熟悉解剖过程。学生可以与该工具进行交互，并定义要移除的器官或区域的区域。通过定义和移除每个连续的器官/区域，可以像在实验室中一样进行解剖。原始的真实色彩被保留在渲染的体量中，以传递真实的生活体验。在模拟器的开发过程中，使用ImageJ的“the Visible Human Preprocessing Toolkit”插件对原始数字图像进行预处理。通过可视化工具包(VTK)进行进一步处理，以删除留在后台的不必要的补丁。通过ImageJ中的“LiveWire”插件对预处理后的图像进行分割。最后，通过VTK进行真彩可视化。我们成功地演示了腹部解剖模拟器。

The increasing interconnectivity of SCADA (Supervisory Control and Data Acquisition) networks has exposed them to a wide range of network security problems. Also in that case WSN (Wireless Sensor Networks, which is a new computing paradigm that emerged from the fusion of the SCADA systems and Ad hoc networks technologies, have gained the advantage over SCADA due to its simplicity and the ad-hoc nature of the network. This paper provides an overview of all the issues that are involved in strengthening the interconnectivity of SCADA networks and how the WSN has gained the advantage as a solution for SCADA. The paper describes the general architecture of WSN and SCADA networks and the properties of some of the commonly used SCADA communication protocols. This paper presents an overview of challenges in the design and implementation of WSNs. It summarizes the potential challenges that influence the WSNs design. Also this paper proposes an example solution to interconnect such environments using low cost and customizable sensor nodes which each has the computational power built in.
