A directional sensing algorithm is proposed employing doppler radar and low-complexity 2-D IIR spatially bandpass filters. The speed of the scatterer is determined by the frequency shift of the received signal following down-conversion. The downconversion is done by mixing it with the instantaneous transmitted signal. The direction of the scatterer is determined by the means of 2-D plane-wave spectral characteristics, using 2-D IIR beam filters. The proposed architecture was simulated for three scatterers at 10,° 30,° 60° from array broadside, traveling at speeds of 31 ms, -1 18 ms-1 and 27 ms -1, respectively. A doppler radar module was used to transmit and receive reflected signals, that has a carrier frequency of 2.4 GHz. Simulations show both direction and doppler information being enhanced.

Start-up marks are considered as one of the major defect in woven fabric, it occurs when the loom is restarted after loom stoppage due to various reasons. This defect is more prominent in high speed weaving looms especially with elastic warp yarns and is caused to deteriorate the fabric quality. This research paper deals with the mathematical analysis of the startup mark generation in elastic tape on narrow fabric loom. Mathematical analysis was carried out for both continuous operation condition and under stopping condition of the narrow fabric loom. A system simulation was carried out using the model developed and compared with the experimental results to show the accuracy of the model.

We developed a new email client which runs on the browser and is not dependent on a particular server, based on the Unhosted web application architecture. The client can connect to any standard mail server directly from the browser, using IMAP and SMTP protocols so that the user is not limited to the webmail clients provided by various email service providers. As our client runs in a browser, it is independent of the operating system. It provides a uniform user experience on any mail system. As a part of our unhosted email client, we have developed a browser extension to allow HTML5 clients to connect to IMAP and SMTP servers. Using this extension, developers may introduce new e-mail clients which are both server and operating system independent. Our client application also provides offline features so that the user can load the application and read/create mail even if he/she is not currently connected to the Internet.

Effectiveness of eLearning has been identified as an important aspect. It determines whether the stakeholders achieve the goals of eLearning. Unlike earlier, eLearning rapidly changes with the introduction of Massive Open Online Courses (MOOC). Since many students got access to experience eLearning via MOOC, perceptions of the factors leading to an effective eLearning changed according to current needs. Many users drop out of eLearning courses due to the fact that it is ineffective in many aspects. It is timely and necessary to address the needs of the users in order to achieve success in eLearning. Finding solutions to the above problem, this research used Grounded Theory (GT) methodology in finding the factors affecting an effective eLearning. We found 10 dimensions which affects a successful eLearning while actively participating in 16 eLearning courses in 5 different platforms in 2 years. This paper explains the process of GT approach which ultimately resulted in the dimensions and the explaining factors in the dimensions leading to a successful eLearning.

Half way through the evolution of supply chain management, the measurement of performance became an important component to the successful implementation of its concepts and practices. The intense competition in the apparel manufacturing industry has encouraged the players to focus not only on the profitability of their businesses but also on the elements such as supplier - customer relationship management and optimization of every single echelon along the supply chain. This research presents a detailed study and an analysis carried out to determine the impact of the performance measurement systems established in apparel companies on their organizational objectives in Sri Lankan context. The apparel manufacturing companies involve in export trade that are registered under Export Development Board were considered as the population and the apparel exporting organisations which are registered under Sri Lanka Apparel Exporters' Association were considered as the sample for this research. All the data is gathered via an online questionnaire and focus respondents are the senior level managers in these apparel manufacturing organizations. In the data analysis phase, the Cronbach's alpha, the principal component analysis and regression analysis became extensively useful. The analysis and the conclusions are solely based on the data collected from the apparel organizations in the export industry and not having even a single representation from non-exporting small scale apparel organisations is seen as a main limitation of this study. This research brought into light that measurement of organisational performance has favourable as well as antagonistic impact on organisational performances, therefore organisations should identify the tradeoffs and set division targets accordingly.

Water diversion mechanisms are commonly used in the irrigation systems and this concept is older than tank (reservoir) systems in Sri Lanka. At present, for water diversions in the wet zone anicuts are constructed by using lifting type gates. Anicuts are used to maintain required water level in the upstream by releasing only the excess water to downstream. In the lifting gate, water is allowed to flow from the bottom and this causes high erosion in the canal. The thrust force due to water pressure on the lifting gate makes it difficult to operate the system and then controlling the system is a complex task. This paper describes the construction and operation of newly introduced flap gates and issues related to lifting gate which are presently used for diversion process. In this analysis, conceptual design of a flap gate with compressive arc type wall plate is proposed to minimize use of construction materials. In the proposed system, height of the anicut could be changed from the top and then the water level in the upstream is not varied much when compared with lifting gates for varying flows in the cannel. According to the practical experiences from implemented proposed systems, controlling of the system is much easier compared to the conventional system.

Solar energy has received increasing attention as one of the potential renewable energy sources for power generation in recent past. Introduction of Net Metering and the increment in provision for renewabIes encouraged the usage of Solar PV systems in Sri Lanka. However, the intermittent nature of solar energy has become one of the barriers for solar energy based power to be integrated to the national power grids. Due to unpredictability solar energy based power plants are non-dispatchable and can cause network instability. With an efficient and reasonably accurate predictable model, a better system balance can be achieved. Shadowing on solar PV modules results in reduction of power produced. Cloud coverage blocking the sun can be identified as the major contributor in shadowing. Identifying and tracking the clouds can be used to finally predict the solar PV output. This paper presents a methodology to obtain cloud image data and an algorithm to process the images which can be used to predict the relationship between the cloud movements and the solar PV output.

Modern communication networks uses optical fibre extensively. The transport networks are upgrading its capacity continuously to provide the bandwidth requirement of the customer requirements. To provide such an increase in bandwidth, the transmission networks are moving from Amplitude Shift Keying modulation methods to Phase Shift Keying methods. In phase shift keying systems, data reception and regeneration required phase synchronization. This requires original optical carrier phase information. In this paper, we report a model for optical carrier recovery for optical synchronization of a Binary Phase Shift Keying input by exploiting Four Wave Mixing in Highly Non-Linear Fibers. The noise influence from the signal laser for the recovered carrier was analyzed.

Lean philosophy has received more emphasize during recent times due to its robust features which facilitate productive manufacturing environments in companies regardless of the type of industry. However, enormous approaches taken to implement lean manufacturing systems inside factories, have failed to achieve desired objectives. This is mainly due to the focus on individual lean attributes rather than considering their collective impact on a system. This paper suggested an approach to measure correlations among lean attributes using their degrees of implementation. These correlations will help organizations to identify lean attributes which are interrelated. The quest is how to measure the degree to which each lean attribute has been implemented within the organization. Different companies have varying levels of lean implementations. Therefore identifying the leanness requires the organization to compare itself against a proxy company who has also implemented similar lean attributes. This research suggested an approach to identify a proxy company and then evaluate the degrees of lean attribute implementations of the selected company. The fuzzy membership functions were used to calculate the degrees. These degrees were then used to figure out possible correlations among lean attributes. The research findings showed that visual feedback made available to the factory floor had triggered a positive impact on other lean attributes in most circumstances.
