Aravinthan, A; Nanayakkara, T; De Silva, C
Humanitarian demining is an urgent and necessary activity to be carried out to resettle in places where the civilians were used to live before the war. Humanitarian mine clearance technology currently used in various parts of the world is based on the use of very basic equipment, techniques, and procedures developed in early years. Robotics has come into all aspects of life today. It has come into the industrial aspect, the biological and practical sciences aspect, everyday life, and especially in the rescue aspect. Humanitarian Demining is one of the areas where the robots can be used to reduce risk and speed up the process. Anovel behavior based mobile robotic platform for landmine detection is proposed in this thesis. A fully autonomous wheeled mobile robot called Autonomous Mine Detecting Robot(AMDR) was designed and developed for this purpose. A microcontroller based system was developed for processing sensor signals and driving actuators. Networks of microcontrollers were used to implement the whole system while reducing complexity of algorithm. Bumper switches, photoreflectors and sonar sensor were used in the robot to sense the world aud two DC motors were used for locomotion. A Subsumption based behavior based controller was implemented to enable the robot to do simple search operation to detect landmines. Six behaviors were arranged according to its priority level. Behaviors were tuned to give better performance.This thesis explains about Humanitarian Demining in the first chapter. The design of the robot and design of the proposed controller are explained in consecutive chapters. In the final chapter the results of experiments are summarized.

(2011) Abeykoon, H; Kaushalya, T; Akram, N; Weerawarana, S; De Silva, C; Dissanayaka, A
Music notations can be considered as very important information for musicians as well as for music fans, To recreate music which WOJ heard before, one has to know the musical notes which were included in that music recording. For many years computer scientists and engineers have tried to come up with various techniques to automate the task of finding out musical notes from a music recording. Many digital formats which facilitate storing and encoding of music information exist. Many statistical methods have been proposed in literature. But implementation specific detail is very scarce. With this paper we try to address that issue. In this research study, we have implemented a system to systematically address the challenges in performing automatic music transcription.

Airline business on the web and challenges for airlines in Sri Lanka
(12/3/2011) Gunasekera, HMG; De Silva, C
107252-1.pdf The Internet is creating opportunities for airlines beyond the traditional air travel business. There has been no turning back from the Internet revolution, and many leading Airlines believe their online channels are vital in reaching out to their customers. The challenge now for Airlines and other companies within the travel sector is not whether to go online, but when and how to obtain the best and fastest return on their investment. It is a proven fact beyond doubt that e-commerce works. Many International & domestic airlines in other countries in the world use their web sites as well as online travel agents sites to earn revenue with high degree of market competitiveness. In Sri Lanka such usage is very low due to various reasons such as technical, investment, economical, social. Also a biggest challenge remains how to use these channels more effectively to cut costs and create new revenue streams. It is important to provide significant new insights into the development and implementation of web business strategies that will lead airlines in Sri Lanka to a competitive advantage. In this process it is possible to assess the current usage of Internet in airline business in Sri Lanka against the usage of other airlines in the world. With this can identify factors and challenges for introducing and developing web e-commerce strategies for airline business in Sri Lanka. This thesis proposes possible strategies to improve market competitiveness in airline business in Sri Lanka using web. Domestic airlines in Sri Lanka can focus on having a web site with at least flight schedule updates, flight booking and FFP as an initial step. Further they can analyze web site access and booking data and decide on future path. National carrier in Sri Lanka needs to plan a web site strategy for next three years. Also it will have to decide on timelines of the project and decide on outsourcing with data security terms. The model identified and explained in this thesis will be helpful in assessing the existing web site strategy and also to focus on future direction for an airlines web site.

An Assessment on suitability of e-procurement for Sri Lanka Railways
Samarasinghe, ATLP; De Silva, C
The level of maintenance of locomotives and other engineering systems of the Sri Lanka Railways : SLR does not meet, the system availability levels, demanded by the train operation and the problem persists even after receiving new rolling stock in recent years. This has been revealed by Railway Performance Reports. One of the main reasons is the non-availability of spare parts and other maintenance items, at the time when they are really required. The railway procurement process is not geared to cater to the requirements of the maintenance departments of SLR. The research was designed, to identify the current problems of railway procurements, including problems experienced by maintenance departments, suppliers and by the procurement (stores) department. It examines how other similar organisations have overcome such problems through application of technology. The existing railway procurement process was deeply studied while studying the procurement processes of other Sri Lankan Organisations in the same manner. Related literature review revealed that carrying out organisational procurements electronically brings many advantages and the current procurement problems of Sri Lanka Railways ' SLR ' can be overcome through implementation of electronic procurement within railways. The survey identified fourteen problem faced by the three groups of stakeholders of the railway procurements. Furthermore, it was found that the other Sri Lankan Organisations who have implemented electronic procurement, also have had similar problems and have overcome those problems through e- P implementations. Based on the survey findings and as per literature review, it is recommended to implement electronic procurement within Sri Lanka Railways and a phased implementation starting from Restricted e- Tendering is recommended. Furthermore, a few improvements and reforms such as, classification of procuring items, with the intension of diversifying procurement strategies and formation of Procurement Circles to expedite the current processes, are recommended.

Wijekoon, WMDB; De Silva, C
It is important tor container terminal operators and administrators to understand the key factors influencing the productivity due to competitive nature of the business. Growing competition among container terminal has forced the container terminal management to develop competitive strategies to attract and retain their customer base. The shipping Alliances that have tremendous command over selection of seaports always set standards and expect very high productivity indicators and service level. The shipping lines and freight forwarders always demand faster response, on-line data availability, online billing and online payments. It is therefore important to have these functions be processed and managed by using an infrastructure with proper Information and Communication Technology (ICT). For the port of Colombo as it is facing severe competition from the seaports in the South Asian region and ports in Far East and Persian Gulf, it is extremely important to have the seaports facilities to meet international standards. At the same time emergence of new terminals, construction of new generation ships, mergers and alliances of shipping lines are also happening. This dissertation analyzes the implementation level of information technologies used in some of the container ports in the region as well as in Sri Lanka. The operating staffs' IT skill is one the factor for productivity since they have to interact with sophisticated ICT systems. It is important to study the actual impact of this factor to the performance of the terminal. The research compares the effect of ICT and IT skills to final productivity in two container terminal in Sri Lanka. It was not found any research done on this area and this is a useful area for future research.

Can actor network theory be used in understanding planning processes?
Ratnayake, R; De Silva, C; Nayomi, HHKR
Planning systems and practices – including plan preparation and implementation- are often comprise of different actors. The engagement of planning professionals in the planning process is not always static. At all levels, different actors play different roles in the planning process. The design and implementation of any planning process effectively, requires an understanding of the complexity of that process and its related networks. This paper proposes a means of mapping the network of resettlement process and housing delivery system in a selected resettlement scheme, applying the Actor Network Theory (ANT). ANT was introduced by Bruno Latour and Michal Callon in 1990s and it treats equally all human and non-human actors and their relationships in a network. Accordingly, the current research considers legal frameworks, policies, acts and laws as non-human actors within the same network where human actors exist. Utilizing a resettlement community in Anuradhapura as a case study, this research focuses on the flow of information between different actors related to the planning process. Different field based approaches were used to trace such flows of relationships between humans and non-human actors in the resettlement planning process. The application of actor network mapping analysis reveals the influence of different human and non-human actors in shaping and reshaping the planning process in plan preparation and implementation.

Customer relationship management systems in the Sri Lankan hospitality industry for sustained growth and development
(12/3/2011) Wijewansa, SM; Randiwela, P; De Silva, C
In the current highly competitive business environment, organizations strive to deliver a superior service to customers in order to gain their satisfaction and thereby increasing customer loyalty and retention. The ability to retain customers is becoming a key determinant that enables organizations to achieve sustained competitive advantage and growth. Customer Relationship Management (CRM) Systems offers organizations the ability of capturing, storing and analyzing customer data in order to gain a better understanding of the customers, which enable the organization to deliver a personalized service. CRM provides the ability of gaining a deeper insight about the needs and requirements of customers and forming more intimate, mutually beneficial relationships with them. CRM Systems, coupled with data mining techniques enable organizations to analyze guest data and unearth a wealth of information regarding the customers. Although implementing CRM provides many benefits in terms of higher customer loyalty and retention levels and higher revenue, the success with CRM has been elusive to many organizations. According to research carried out in CRM implementations, over half of CRM efforts do not deliver the expected results. The causes of the failures vary from ineffective CRM strategy and organizational and human issues to implementation issues. The objectives of this research are to analyze the current usage of CRM Systems in the Sri Lankan hospitality industry and to identify the constraints that are encountered during CRM implementation. Finally, the research analyzes the applicability of existing CRM Systems implementation frameworks to the Sri Lankan hospitality industry, and proposes recommendations for a localized framework, which can be adopted by the Sri Lankan hospitality industry. The research was carried out using a case based qualitative approach. A literature review was carried out in order to analyze the existing frameworks for CRM implementation and to identify the critical success factors pertaining to the hospitality industry in general. A preliminary study was carried out with individuals from the ii industry to gain an understanding of the factors critical in the local context and also to identify any other relevant factors that was not evident from the literature review. A conceptual model was formed using the factors identified from the literature review and preliminary study, which was used to execute the research. Subsequently, a series of in depth interviews based on the conceptual model was carried out using a suitable sample from the Sri Lankan hospitality industry to identify the effect of the factors that influence the implementations. The findings of the research indicate that CRM in the Sri Lankan hospitality industry is still in its infant stages, initiated mostly by hotels belonging to the high-end segment. The majority of the difficulties encountered during CRM efforts are in the areas of strategy development, organizational & human development, technology and implementation. The proposed framework and recommendations have taken all factors that affect the CRM implementation in the local context into consideration as well as the scale of the CRM initiatives by local hotels.

Developing a suitable method to evaluate mobility levels in urban areas of Sri Lanka
(Sri Lanka Society of Transport and Logistics, 2020-11) De Silva, C; Kavindya, PBKC; Gunaruwan, TL
This paper aims to develop a suitable method to measure urban mobility in Sri Lanka using an appropriate indicator set. The study only focuses on vehicular mobility. The study covers four sub-objectives: review and identification of the limitations of existing evaluation methods, application of already developed evaluation mechanisms to Sri Lankan context in comparison with foreign cities, determining the best criteria to analyse the mobility index for the selected case studies, and urging decision makers to take necessary actions to upgrade the mobility index in Sri Lankan cities. The proposed method includes 13 indicators related to vehicular mobility. Methodology includes creating a definition using cluster analysis, deriving suitable parameters according to content analysis, expert survey and factor analysis in the preceding part. Data analysis is performed using different formulas and spatial analyses, a mobility index is developed using arithmetic mean, and the index is applied to selected case studies from Colombo, Kandy and Galle. The “Urban mobility index” and “Sampling mobility index” are also applied to those cities. Non-judgmental probability sampling method was used for expert analysis with 22 experts participating. Random sampling was used for the public survey. Sample size was 140 from each city. Five experts validated the method. According to the findings Colombo and Galle cities have barely acceptable mobility levels, and in order to improve indicators returning lower values, some targets should be established. Kandy has an unacceptable mobility level. This is not critical but in order to reverse the situation, there should be immediate interventions from society and administrators. Moreover, in the final part of the research, it is expected to urge decision makers to take necessary actions to upgrade the mobility level in Sri Lanka. These indicators will demonstrate areas that should become policy priorities in future. After achieving acceptable mobility, more indicators can be incorporated to the index.

Development of a gamified application to enhance flood disaster education among children and youth
(Faculty of Graduate Studies, 2024) Mahamood, R; Kankanamge, N; De Silva, C; Ranasinghe, D; Kangana, N
Disasters, whether natural or man-made, pose a serious threat to the security and well-being of people everywhere. One in every 100 years floods directly damage 23 percent of the world’s population, or 1.81 billion people. Out of that 1.24 billion people live in South and East Asia, which 16% - 23% of them are Sri Lankans [1]. In Sri Lanka, flood-related losses and damages were over USD 2 billion between 1990 and 2018 [2]. It’s critical to manage and prevent disasters using proactive strategies in order to reduce the possible hazards to people and infrastructure. As a result, it is impossible to overestimate the significance of disaster awareness as a preventative strategy for disaster management.

Development of a mobile augmented reality application to enhance youth engagement in planning and designing public spaces in urban areas
(Faculty of Graduate Studies, 2024) Ranasinghe, D; De Silva, C; Kankanamge, N; Mahamood, R
Urban planning necessitates public participation to ensure that every individual’s voice and requirements are heard and considered, thereby promoting inclusive urban development. According to UN-Habitat (2018), public participation fosters a positive relationship between a government and the public by communicating effectively and solving conflicts collaboratively. Despite the theoretical emphasis on participatory planning in planning practices, research has identified a lack of community participation in planning-related contexts, leading to the current gap between urban planning and public participation. The incompatibility between communication preferences and the public’s preferred method of engagement significantly contributed to the lack of public engagement in urban planning using traditional approaches [1]. Furthermore, in the local context, the existing participatory planning methodologies are outdated and fail to motivate people to voice their opinions. Given this situation, we hypothesize that incorporating advanced digital technology and an augmented reality application into a participatory planning methodology could enhance community involvement in planning and de-signing public spaces in cities based on their needs.

Development of a mobilized crowdsourcing platform to enable participatory risk sensitive urban development.
(Faculty of Graduate Studies, 2024) Kangana, N; Kankanamge, N; De Silva, C; Ranasinghe, D; Mahamood, R
According to United Nations Development Program (2021) nearly 84% of the fastest growing urban areas are facing extreme climate and disaster risks especially in Asia and Africa. In Sri Lanka, it is ranked 63 (out of 171 countries) on the World Risk Index and 56 (out of 191 countries) by the risk assessment platform of countries that are exposed to disaster risks [3]. According to the hazard profile of Sri Lanka, over 50% of the highly populated cities are located in disaster prone areas. Sri Lanka is a developing country, facing highly challenging situations with governance deficits, and resource constraints. Therefore, risk sensitive urban development approaches have been a crucial concern in developing cities, where it integrates disaster risk reduction and adapting the climate smart measures into development planning across all sectors of development that help to protect development outcomes and investment made towards achieving development goals [3]. Disaster-vulnerable communities need active engagement in risk management to prepare, respond, and recover from disasters, utilizing their understanding on the risks and vulnerabilities they face and access to local resources and knowledge [2]. Therefore, participation of vulnerable communities within the decision-making process in risk sensitive urban environment is important. However, vulnerable communities are often marginalized in the decision-making process [1]. In the Sri Lankan context, community participation has been a least vital consideration in urban planning, not only in disaster risk reduction. Most importantly the existing attempts are lacking with the public participation where the awareness, trust, and interest of people towards the process has been marginalized.

Dye - sensitized solar cells: using over 100 natural dyes as sensitizers
Attanayake, CIF; De Silva, C; Premachandra, BAJK; De Alwis, AAP; Senadheera, GKR
Over 100 natural dyes extracted from fruits, leaves, flowers, stems, bark and roots of plants growing in Sri Lanka were used as sensitizers of to fabricate dye-sensitized solar cells (DSSC's). Preliminary investigations on the identification of natural pigments in the dye-sensitization of nanocrystalline n-type Ti02 were carried out. Fresh extracts of various fruits and vegetables were employed as sensitizers in thin layer sandwich type photo electrochemical dye - sensitized solar cells (DSSC's). After electrical and electronic analysis, of several natural dyes of local plants, it was observed that many useful dyes which could be extracted from natural products by simple procedure could be used as photo sensitizers for DSSC's. It was also observed that dye extracts of Mangoostein yielded better results. The current-voltage curves obtained with solar cells employing the photo anode with Ti02 sensitized by different dyes were observed. The values of short circuit current density (Jsc), open circuit voltage (Voc), fill factor (ff), and efficiency fa) obtained for solar cells employing photo anodes with Ti02 sensitized with different fruit / vegetable extracts were noted. The dye extracts of Mangoostein fruit were found to be superior to those obtained from other dyes , and were Jsc = 2.56mAcm2, Voc 6S5.3 mV, ff = 60.02 %,n = 1-053 %. Also Ekkiriya wood, Egg Plant, Karawilla kabilla yielded Jsc, Voc, ff and /? of 2.32 mA.cm2, 414.2mV, 56.86%, 0.547% respectively; 2.096 mA.cm2, 410.4mV, 56.42%, 0.485%; 1.395 mA.cm2, 443.5mV, 58.58% and 0.362%.

Effectiveness of it applications on consumer complaints for improvements in water supply: a case study with analytic hierarchy process
(Department of Civil Engineering, 2023-09-27) De Silva, C; Gunawardhana, L; Abeykoon, H; Mallikarachchi, C
Consumer complaints are crucial to improve the quality of any service. These complaints mean expressions of consumers’ dissatisfaction with the services they receive. Not handling consumer complaints efficiently and neglecting the complaints can delay the service provider's work. On the other hand, successful attendance to these complaints helps to increase the reliability of the services and reduce negative attitudes of consumers, which in turn boosts the reputation of the service provider. In the context of the National Water Supply and Drainage Board (NWSDB), customer complaints have been instrumental in identifying pipeline leakages. The objective of this study is to identify the factors that affect leakages and, accordingly, develop a susceptibility map for the Biyagama area of the Gampaha district. According to past studies, various factors contribute to leakages in water distribution networks, such as pipe age, diameter, pressure, length, and depth of placement. In this study, the United States Environmental Protection Agency Network Evaluation Tool (EPANET) was used to model the water distribution system in Biyagama area and analyse the hydraulic properties. Considering the qualitative nature of some of the influential factors, multi-criteria decision analysis (MCDA) was employed. The analytical hierarchy process (AHP), which is one of the MCDA techniques, was used to assess the significance of influential factors for pipe leakages. Actual weights for each factor were calculated and normalised. The AHP values were adjusted accordingly and compared with the actual leakage data to calculate the error margin. The weightages with the minimum error were selected for the susceptibility analysis. Accordingly, the analysis reveals the most vulnerable locations for pipe leakages and the importance of influential factors. The AHP results indicated that the depth of placement, pressure, diameter, pipe length and the water velocity, in accordance with their significance, play a crucial role in identifying leakage locations. The analysis classified the study area based on level of susceptibility for low, moderate, and highly vulnerable classes. The results demonstrated that under highly vulnerable conditions, 415 predicted leakage points out of 2207 (19%) matched the actual leakage points. When considering both high and moderate categories, the accuracy rate was increased to 81%. The study was able to identify the critical areas of the Biyagama water distribution system to efficiently attend to customer complaints. The developed methodology can be applied in other areas of the country to act proactively, which lessens the maintenance cost and avoid or reduce impact of damages.

Evaluation and analysis of mobile payment adaptation in Sri Lanka
Perera, BMN; De Silva, C
The dramatic increase in mobile phone usage and mobile application usage within the last decade has shifted the would from e-commerce to m-commerce era. As a result today lots of research have being conducting on rn-cornrnerce in all over the world. Mobile payment (rn-Payrnent) is one of the latest services of the m-cornrnerce technology and is becoming more and more popular. The main objective of this research is analyzing and evaluating the factors that affect rn-Payrnent adaptation in Sri Lanka. When compared to the other countries in the region, Sri Lanka has a highest mobile penetration of 30% of the population. Therefore m-Payrnent can be used as an alternative for micro payments to break the infrastructure barrier in other technologies such as internet. But it is really important to identify the critical success factors and the correct technological and business model for m-Payment service in the context of Sri Lanka. There are lots of research and theories on rn-cornrnerce technology adaptation such as Davis' Technology Adaptation Model [29], theory of perceived risk [39], switching barrier theory [44] etc. In this research, 14 concepts have been developed based on the previous research findings and theories and hypotheses have been developed base on those concepts to evaluate the effect on those factors on rn-Payrnent adaptation. Even though the target population is the mobile phone users in Sri Lanka, due to various limitations such as time, cost and resources ICT (Information and Communication Technology) professionals have been used as the sampling population for this research. Data were collected using a questionnaire and both hard copies and soft copies were distributed to more than 600 ICT professionals. There were 238 valid respondents which were used for the further analyzing and results and conclusions were developed based on those data. It was found that the Cronbach's Alpha of the collected data is 0.867 which can be considered as a very high reliability factor. Pearson Correlation was used to analyze the relationship between individual concepts and regression analyze method was used to analyze the relationship between the dependent variable and the multiple independent variables and to develop a model for the variables. Analysis proved that the usefulness, ease of use, risk factor, attractiveness of alternatives and personal factors such as age, gender and usage of mobile applications and services have a greater impact on the adaptation of m-Payment services. And it was found that the perceived ease of use and perceived usefulness are directly affected by the awareness, perceived switching cost, merchant acceptance, task technology fit and perceived confidentiality. During the analysis it was revealed that there is a huge usage of SMS (Short Message Service) applications when compared to WAP (Wireless Application Protocol) and GPRS (General Packet Radio Service) applications.
