A Study of professional ethical behaviour of Sri Lankan software engineers
Wijayasiri, PAIA; Weerasinghe, C; Gamage, C; Nanayakkara, V
Information systems have become an integral part of our lives supporting us in numerous ways, be it banking, accounting, medicine, education or any other discipline that could be complemented by the use of proper information systems. Among the group of personnel engaged in the management of information systems, software engineers in particular playa vital role as individuals who are directly involved in the creation of these systems. Consequently, software engineers could be considered as having a major accountability for the positive or negative impact of a system on its end users. Many cases have been observed in the past, of attempts at system implementations that have failed due to various reasons. Some failures have been directly attributed to flawed software engineering processes. Realizing the pivotal social role played by software engineers, the professional ethical behaviour of software engineers has become a widely discussed topic, internationally. The previous researches on professional ethical behaviour have focused on disciplines such as Accounting, Medicine, Information Technology and Sales. In these studies, age, gender, education, experience, culture and personal attributes have been considered important as factors affecting professional ethical behaviour. Interestingly, while some researchers have observed a relationship between these factors and professional ethical behaviour, others have concluded that there is no relationship between them with regard to certain factors. The present study analyses the impact of a selected set of factors on the professional ethical behaviuor of Sri Lankan software engineers. In addition, the level of awareness of Sri Lankan software engineers of international codes of conduct and the codes of conduct of th~ir respective organizations is also analysed. The analysis of the data collected through a questionnaire revealed that the organizational culture seemed to have a positive correlation with the professional ethical behaviour of the Sri Lankan software engineers while, age, gender, work experience, being a member of a professional body, having followed a course on professional ethics and the level of education had no impact on it. The awareness of the Sri Lankan software engineers of the international codes of ethics and the codes of ethics of their organizations was found to be at a low level. The results of this research are presented and discussed analyzing their implications further. Accordingly, recommendations are made to the management services with a view to helping them promote and encourage professional ethical behaviour of software engineers in Sri Lanka.

(2011) Sooriyabandara, E; Jayawardena, I; Gallaba, K; Pavalanathan, U; Pathirage, M; Nanayakkara, V;
The use of process modeling concepts in business scenarios enables designers to specify process requirements 0 in terms of interactions, enacted by human agents. Inter-operation of Business Processes at the human level, c rather than the software engine level, can be solved with the standardization of the Business Process Mode1 n and Notation (BPMN). BPMN 2.0 is a step forward for the whole business process management community j because it introduces not only a standard graphical notation, but also concise execution semantics for process ( execution, that can be used to enable the real execution of business processes which are modeled using it. ; In this paper, we analyze BPMN 2.0 standard with regard to its expressiveness as a Business Process , Execution Language and propose an implementation of a native BPMN 2.0 execution engine using Apache ODE's JACOB framework.

Combined symbolic and numerical methods for solving equational systems
(1998) Nanayakkara, V; Dias, G
In this paper we discuss systems developed to assist scientists and engineers to solve their problems based on mathematical models using numerical and symbolic methods. Numerical library routines for numerical algorithms and Computer Algebra Systems (CASs) for symbolic computation are both now well established areas. The recent research interest in these areas is oriented towards combining these solvers, rather than on improving the individual solvers. We analyse the state of research in numerical and symbolic solvers as well as the area of these combining methods or coupled (or combined) systems as they are commonly referred to. We evaluate these coupled systems to identify their essential features and various methods of integration. Based on our analysis we then propose a new strategy for integration which can enhance the facilities provided by the existing symbolic and numerical systems.

Diaspora contribution to IT entrepreneurship in Sri Lanka
(2015-01-27) Abeyasekera, N; Nanayakkara, V
One in every ten Sri Lankan lives abroad. Modern ICT and transportation facilities have increased labour mobility and the creation of transnational communities. Diaspora members could be resourceful in two ways to their home country, through discussions and transactions. Discussions include email, instant messaging, websites, forums and social media through which Diaspora maintains close relationships with those living in their home country and others living abroad. Transactions include remittances, investments and commitments in terms of time and knowledge. The key feature of Diaspora is their retained affinity to their home country and high motivation to contribute to its development. This research study is focused on Diaspora contribution to the Sri Lankan IT industry. Leaving aside the diverse composition of the Diaspora, it's influence on events in the country and the many ways they contribute to the economy, the author delves into the background of 23 individuals who went overseas for higher studies and returned back to initiate businesses, often as 'first movers' in the field. An industry that started off with a few multinational companies providing IT infrastructure and services two decades back, saw the emergence of local firms around the 90s entering the application products, software services, off-shore development markets and later the IT BPO market. Behind these developments are Diaspora members who have done pioneering work, giving their knowledge and expertise and often acting as the catalysts in the industry. They use their global networks to launch new businesses for foreign markets and to find the finances to support new ventures. In an era of globalization where skilled migration is inevitable this study looks into ways the country can benefit from its Diaspora. What attracts the Diaspora back home - especially the student population studying overseas? What can the government and the various supportive institutions do to encourage IT entrepreneurship? These are the questions answered in the pages that follow.

Distributed management systems for unmanaged UPS
Punchimudiyanse, M; Nanayakkara, V
Information and communication networks have transformed the world to a global village. A typical distributed local area network often consists of one or more network distribution cabinets powered by uninterrupted power supplies of various capacities ranging from 400VA to 2 KVA. Maintaining high availability at correct time is the key issue faced by technical personnel involved in network maintenance today. The research project "Distributed Management System for Unmanaged UPS" IS intended to provide effective monitoring of environment and timely notifications of status or interruptions to background services such as electricity and temperature control of the distributed network locations by a remote unit installed in each remote location .The status of the remote location is sent back to a central software module through Ethemet network then to appropriate technical personnel for necessary actions. The research project utilizes embedded electronic device and sensors with some custom programmed or pre programmed intelligence to monitor and control equipment at the remote network locations. An embedded device named TIN! "Tini Inter Net Interfaces"[I], [R] is used in order to monitor the status of UPS using smart/ non smart serial protocol of the UPS via its serial port to measure the electrical stability of re mote location, and uses a temperature sensor to get feedback on temperature status of the remote location. Immediate evasive actions also triggered automatically in temperature increases without intervention from teclmical personnel. A central software module with real time status monitor is used to integrate status logging and alerting on behalf of remote units. SMS and Intercom alerts arc used as a lerting mechanisms with specified I customized thresholds, messages suiting to each remote network location and alerted only to personal intended to attend to specific location.

Earning expected benefits of ERP for insurance organizations in Sri Lanka : implementation perspective
Atulugama, SR; Prasanna, R; Nanayakkara, V
During the study of the research gap it was found that there are many complain in sustainability of benefits in insurance ERP implementation projects. These complain are due to not meeting expected benefits from the implementations or declining the initially acquired benefits. There is very little study done in this area and in fact, any study in Sri Lankan context could not be found. Consequently this research has three main aims. First is to identify important factors that influence gaining sustainable value from ERP implementations in insurance organizations. The second is to identify the degree of criticality ofsuch factors for post implementation success and value addition. The third and the final is to formulate a framework or guidance with such factors to facilitate ERP implementations for insurance organizations in Sri Lanka The study was based on the data collected from insurance professionals in Sri Lankan insurance industry representing various capacities. There were 24 semi-structured interviews conducted. The analysis of findings was formed into 32 arguments and a questionnaire was submitted to same respondents and few additional professionals to identify the criticality of derived factors. In addition the information from two real life projects concluded recently was included. The final results were further analyzed with previous literature and developed a guidance using 20 important factors to consider in depth in order to get sustainable benefits from the insurance ERP implementation projects. The outcome of this thesis has achieved a guidance to acquire sustainable benefits from insurance ERP implementations, which in also reflect to facilitate as a mitigation plan for insurance ERP project implementation risks. This would be an interesting information for prospective project managers those who expect to implement other insurance information systems too.

Factors affecting use of IT tools for secondary education in Sri Lanka
Maduranga, JAG; Nanayakkara, V
In a developing country, education has become an essential factor for the achievement of a stable economy. A country requires a good and modem education system to produce professionals whose contribution is ultimately to become a strength to the country for its development. Therefore, the investment in education provides a path for economic growth in Sri Lanka for which the responsibility ofthe government is to provide modem and quality education to every student. Free secondary education has already been implemented and according to the latest educational statistics, there are 9,662 schools, 212,683 teachers and 3,929,234 students in the country but the current education system is not at an up-to-date standard in using IT. Information Technology has been already incorporated to the current education system through different methods such as establishing computer labs in schools, educating students and teachers on the use of IT, incorporating IT as a subject in the curriculum, etc. The use of IT tools has been recognized as a new concept and the students get familiar with that technology only in the university environment. Hence, if the student had absorbed the technology during his/her secondary education, he/she would have been more productive in the university environment. The aim of this study is to find out the factors affecting the use of IT tools for secondary education in Sri Lanka. The IT tools are driving forces to provide quality education to the students. The main human resources of the education system are teachers who teach, guide, instruct and stimulate students to be successful in their future with quality educational qualifications in hand. Special emphasis ofthis thesis is the perception ofteachers on the factors affecting the use ofIT tools in teaching & learning process ofthe secondary education. The research utilized the survey method and questionnaires were used to collect data from 370 teachers. Interviews were conducted with 7 IT and Non IT teachers as the pilot study and data was collected from 279 teachers (208 Non- IT teachers and 71 IT teachers) from all provinces in the country. A qualitative analysis of questionnaire data and interview data were presented as the outcome ofthis research. Findings of this research were categorized into variables in the Technology Acceptance Model (TAM). Analysis was done according to the mapped variables of the TAM and the responses received for each question of the questionnaire. The acceptance ofthe TAM in secondary education is tested by using the responses to the questionnaire and interview data. As the main out come, very less IT facilities available in schools, the operational and maintenance issues, insufficient training and financial issues negatively affect the smooth operation ofsecondary education in the use of IT tools. The recommendations given as the outcome ofthis research can be considered for improvement in the secondary education in Sri Lanka.

Factors for LGN usage by staff officers of divisional secretariats in Colombo district
Roshini, SS; Nanayakkara, V
Lanka Government Network (LGN) is the common infrastructure and the link that provides secure and reliable connections between government entities and e-government initiatives. E-mails and VoIP phones are the main facilities provided by Lanka government Network. It is obvious that the Colombo district is the pioneer of e-government implementation in Sri Lankan divisional administration due to its superior leadership and readiness to practice e-government initiatives. Though ICTA has provided LGN facilities, some observations and survey reports reveal that these facilities have not been fully utilized. The technology acceptance of the staff officers is determined for the purposes of this study through the usage of Lanka Government Network. The main objective of this research is to determine the present usage level and the difficulties in usage of LGN e-mails and VoIP phones. The research is focused on strategies for motivating LGN usage. In the Literature review the relationship among ICT usage, Perceived Ease of Use, Perceived Usefulness and the skills and knowledge of the officers has been discussed using the Technology Acceptance Model (TAM). Information was gathered using questionnaires and interviews, from a sample of sixty staff officers covering each divisional secretariat of the Colombo District. Questionnaires were distributed to forty five subjects to determine the usage level, ease of use, frequency usage and reasons for not using e-mails and VoIP phones. Fifteen officers were interviewed separately to find out the reasons why they have never used the above facilities and their requirements by way of facilities and training. It was concluded that the low usage of VoIP phones indicates that it is not a satisfactory device for communication. It was felt by the majority of the staff officers that it would be easier to use the LGN e-mails. Most of the officers are qualified in ICDL. The staff officers feel positively about the Ease of Use of LGN e-mails, but frequency usage of LGN e-mails and VoIP phones are at a disheartening rate.

A faster image registration and stitching algorithm
(Computer Science & Engineering Society c/o Department of Computer Science and Engineering, University of Moratuwa., 2009-07) Senarathne, N; Ransiri, S; Balasooriya, A; Arangala, P; De Silva, CR; Nanayakkara, V; Gunasinghe, UP
This paper presents a new algorithm for Image Registration and Stitching. The algorithm is designed to be extremely efficient and fast in its execution and is intended for use in stitching images extracted from a video stream of a camera. This algorithm is not universally applicable to all the image registration and stitching problems. It is customized to be used to generate single images of surfaces such as a conveyor belt or undercarriage of vehicles, which cannot be captured by a single photo. The algorithm works by extracting edges of the two images to be registered. Then it selects a reference section from the first image and search in the second image where it finds the best match for that section. The best match is the least difference score. The section in the second image which gives the least difference score is then identified as the registration point between the two images. The speed of the algorithm is improved by using heuristics to restrict the search space in the second image. We present full details of how the extraction of the heuristic is done from the inputs and how it drastically reduces the execution time of the algorithm. The implementation of the algorithm was done in MATLAB and the details of the MATLAB functions are listed in the paper. The paper also contains a full section on comparing our algorithm with a set of existing algorithms. Our algorithm outperforms the existing ones for all the common image sizes.

Feasibility of using eLearning in capacity building of ICT trainers and delivery of eLearning courses in TVET sector in Sri Lanka
(2016-07-15) Jayalath, JADJ; Nanayakkara, V
Capacity building of instructing staff in Technical Vocational Education and Training (TVET) sector in Sri Lanka is a prevailing difficulty. Trainer competencies on technology are to be continuously upgraded to match the industry developments. Geographical distribution of the trainers throughout the country adds more complications for fulfilling this need of on-going, real time training of the trainers. Therefore this research has been focused on analyzing whether eLearning is a better alternative to deliver trainer training programs for ICT trainers in the TVET sector. Further the feasibility of converting some selected training courses in to eLearning based material is evaluated. The existing literature was reviewed to identify the major requirements of conducting trainer training programmes and delivering such programmes in eLearning environment. Based on the identified requirements, a questionnaire survey was conducted for main stakeholders namely trainees, trainers and TVET administrators. The survey was conducted according to a sample selected from the population using simple random sampling method. An extensive analysis of the collected data was the basis for final recommendations. From the survey, several favorable indications were revealed in the areas of English language ability, effectiveness of training delivery and trainers with good educational background which are plus points for implementation of eLearning. The need for trainer training is specially elaborated in the areas of eLearning strategy, technology and the technical support on learning management systems. The need for awareness in eLearning is identified in many instances of the research outcome. When considering the outcomes from all three categories, there is a very high potential to change the traditional course delivery methodology to eLearning. Several recommendations in the broad areas of infrastructure, training and institutional requirements were made for the development and implementation of eLearning in TVET sector in Sri Lanka. Infrastructure development was a key recommendation with setting up of centralized server facility including internet connection to every ICT training center. Trainer capacity building and thereby converting traditional training course modules to eLearning based materials were some important recommended activities.

(2014-06-24) Kodithuwakku, S; Padmakumara, L; Premadasa, I; Rathnayaka, S; Nanayakkara, V; Perera, S
Management of a large scale distributed system presents several issues such as managing a network of thousands of nodes, keeping the system up to date when nodes are added, deleted, changed and detecting and recovering from failures. With all these challenges, required features of a distributed system vary from organization to organization. Here we present 'GajaNindu', a distributed management framework, which facilitates user-defined management rules. This feature provides organizations with the capability of modifying the framework according to their business/organizational needs. Open source technologies (Apache Zookeeper, Apache Thrift and Jboss Drools) have been used to implement a prototype of the concept.

Generationally significant work values and their impact on employee retention in the Sri Lankan IT industry
Gnanarathne, DMSP; Nanayakkara, V; Gnanarathne, D.M.S.P. (2013).Generationally significant work values and their impact on employee retention in the Sri Lankan IT industry [Master's theses, University of Moratuwa]. Institutional Repository University of Moratuwa. http://dl.lib.mrt.ac.lk/handle/123/14059
Generational diversity is a strong dimension in society diversification. The groups can be differed in many various ways due to their fundamental approach to work issues, different lifestyles and social values. All ofthese have a significant weight in the workplace. Each generation views the world through their own generational experiences and influences; and it is these factors that shape the core values of a generation. For the first time in history four generations are in the global workplace simultaneously. In the current working environment people are as young as their children and as old as their parents but they are working in a team to achieve company’s common objectives. It is very important for employees to know how to connect with each other representing different generations at workplace more than ever before. Appreciation and greater understanding of the generational diversity that exists within the society and workplaces will enable to leverage on the differences, giving individuals and organizations greater competitive advantages. There are various benefits in understanding generational diversity in greater depth as increased awareness of generational backgrounds and how they impact on software team, communication, generational similarities and differences. Misunderstanding, miscommunication, conflict, dissatisfaction and de motivation can arise due to generational diversity. So the corresponding loss ofproductivity and performance in companies also arise (Bernstein, Alexander and Alexander, 2006). The most valued work values of each generation and impact analysis of generational diversity on retention in the context of Sri Lankan IT companies are yet to be done. This research intends to fill these gaps. The theoretical framework is developed based on generational work values and the categorizations of each impact on the employee retention. This framework was used to identify most significant work values of each generation in Sri Lankan IT industry and the degree of each work value category’s impact on the employee retention. The conceptual framework was developed based on the theoretical framework. An online questionnaire was used to collect data from employees in Sri Lankan IT Organizations. Research results indicate that most of the employees in Sri Lankan IT industry belong to Gen-X category and Gen-Y category. Therefore this research studies carried out was based on generation X and generation Y. According to the results, while gen X employees selected ‘job security’ as the most valued work value Gen Y selected ‘economic return’ as the most valued work value. Those work values were selected out ofsecurity, way oflife, economic return, management, variety, prestige, independency, intellectual stimulation, altruism, creativity and associate. The research also reveals comfort and security, professional growth, personal growth, and working environment positively impacts on employee retention in Sri Lankan IT industry. This research identifies the current generational diversity behavior of IT industry and generation wise level of importance of several work values influencing the employee efficiency and productivity. The efficiency in future IT workforce will be increased ifthe identified factors are taken as suggestions and necessary steps be taken to enhance the IT industry environment based on employee work values. Thus the findings of this research project will be useful for IT employees, IT management, and owners. This would ensure retention of valued employees in the organization and reduction in misunderstanding, miscommunication, conflict, dissatisfaction and de-motivation among employees.
