Designing a PABX system using the existing power line infrastructure as the transmission medium is an effective method of implementing a fast and easily installable communication solution. The scope of this research is to develop such a system for a small scale organizational environment to avoid the complexities and time consumption of cable installation. As the power line transmission technique, we used narrowband frequency shift keying to counter the noise disturbances in power line. In addition we used a novel communication protocol to further reduce the effects of noise and to achieve reliable transmission. We integrated the switching function into the central unit which is the central control element in the system. We were able to achieve voice communication at the rate of 2kbps and to switch between four extensions. Further improvements in the voice quality can be achieved by using advanced noise reduction algorithms.

The performance of neuro-fuzzy traffic signal control at two independent traffic junctions is discussed. In this work, traffic conditions at two 4-way traffic junctions were simulated and flow of traffic on the road connecting the two junctions under varying traffic conditions was studied. For a given data set, the developed neuro-fuzzy system automatically draws membership functions and the rules by itself, thus making the designing process easier and reliable compared to conventional fuzzy logic controllers. The traffic inflows of roads are given as inputs to the fuzzy control system which generate the corresponding green light time as the output to control the signal timing. The control systems try to minimize the delay experienced by the drivers at the two traffic junctions. As expected, when compared with a fixed-time signal control system, the neuro-fuzzy system tends to minimize vehicle delays at both junctions. Simulation results show, under variable traffic conditions, neuro-fuzzy control system perform efficiently by making average delay per vehicle under the red light phase smaller and increasing the synchronization of green light phases between junctions. When the volume of traffic at one of the junction changed abruptly, the green light timing of both junctions changed, adapting to the new traffic condition on the road connecting the two junctions.

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.

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.

The geospatial information is becoming an integral part of many decision making processes, specially related to socio-economic development. Geospatial data are often collected and maintained by different organizations and become a major bottleneck for spatial integration. Further, the spatial relationships between various spatial objects and the influence on each other are often not defined crisply. There exists a spatial or thematic relation between the data of different themes. In real world situations, inferring accurate relationship between the data of different themes is not possible. In order to address this inaccuracy and uncertainty, a fuzzy logic concept has to be used. In this paper, a framework has been proposed to integrate these diverse data using fuzzy spatial web services. The framework uses fuzzy geospatial data model to integrate the data across various organization. Such data model is developed based on base feature set, domain knowledge and fuzzy logic. The association between data of different themes derived from domain knowledge and fuzzy logic is used to map the uncertainties between the relationships of these diverse data. A database has been designed and populated using the fuzzy geospatial data model. The data are integrated and accessed through Enterprise GIS Framework geospatial web service that conforms to OGC (Open Geospatial Consortium) geospatial web services. For analysis and decision support a fuzzy decision system has been used implemented using fuzzy logic concepts.

Traceability systems have become a dominant management information system within the production and marketing companies as they can efficiently control the supply chain, by minimizing the risks of the production process, and helping to enhance the consumer/customer reliability on products. There may have some limitations of using available traceability systems with small and medium scale industries as there may have design-reality gap of such systems.

The Axial Flux BLDC motors are relatively new, specially at higher power ratings over 10kW. Therefore the designers face a lot of difficulties in designing and optimizing the motor for a given application. This paper presents a new method to optimize the performance in speed, torque, torque stability, power output, power density and motor dimensions in view of the cost and reliability for a given motor; specially to be used for traction purposes. By this method, the motor designers can easily choose the exact parameters of the motor to match the requirement and make sure of the optimization of the design. A software interface and simulation results are presented to check the level of optimization achievable with the system. This paper discusses a three phase axial flux outer rotor BLDC motor, but the core equations can be easily changed to simulate for any kind of motor with the same software and simulation interface.

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.
