Drown Prevention and Flood prediction using smart embedded devices
(IEEE, 2019-12-05) Samarasinghe, D; De Silva, P. M; Mudalige, T. U; Gamage, M. K. I; Abeygunawardhana, P. K. W
Drowning and Flood becomes major negative impact to the mankind and infrastructure. Drowning is caused by the when person go into deeper areas or else due to a person's health condition. Flood is a natural disaster commonly caused by the run of rivers due to excessively highly rainy season or due to environment effect or global warming effect. Hence IoT with sensor technology support us to efficiently cover up this impact for mankind. This research support for each mankind to survive from the drowning threat and this may help for people to survive from the natural disaster like flooding. This research presents two IoT Devices consisting with sensors and monitoring system to determine the flood level, the user condition and water level when user in the water. Then generating alert via the mobile application to notify the user. Machine learning algorithms were implemented to perform the level classification.

Factors affecting successful implementation of lean manufacturing tools and techniques in the apparel industry in Sri Lanka
(SSRN, 2011-04-27) Silva, N; Perera, H. S. C; Samarasinghe, D
Lean Manufacturing is a business strategy which was originated and developed in Toyota Motor Company, Japan. It is useful in identifying waste associated with processes. As a result companies can improve their productivity and quality and can achieve a competitive advantage over others. Lean Manufacturing was originated in automotive industry and then later on spread to many other industries in both developed and developing countries. In implementing this concept Toyota has introduced and developed many tools and techniques which can be used effectively. In Sri Lanka, apparel sector is the leader in implementing Lean Manufacturing. However a little research work is carried out in regarding its suitability. Therefore in order to fill this empirical gap, this research is an attempt to identify factors such as suitable methods of implementation, order of implementation, challenges, how to overcome those challenges and benefits of implementing Lean Manufacturing concepts in the apparel sector of Sri Lanka. The study first undertook literature review in the field of Lean Manufacturing. Then it developed broader research questions and administered them to fifteen apparel manufacturers in Sri Lanka using personal interviews and observations methods. The sample firms were selected judgmentally. In analyzing the data descriptive statistics and qualitative techniques were used. The result of the study revealed factors such as implementation strategies, order of implementation, challenges, how to overcome those challenges and benefits have influenced the successful implementation of Lean Manufacturing in mass production apparel industry. Since Lean is new to most of the Sri Lankan apparel manufacturers, the full benefit is not yet achieved. But current situation suggests that the industry can go forward with Lean.

Job seeker value proposition conceptualised from the perspective of the job choice theory
(2023-04-27) Jayasinghe, S; Suraweera, T; Samarasinghe, D
The job seeker value proposition (JSVP) can be defined as a set of benefits or values a firm promises its job seekers to deliver once they join it, signifying an indicator of its employer brand as well as focusing on job seeker attraction because it carries some information that helps the decisionmaking process of the prospective employees. In this concern, the job choice theory interprets the actual factors of a job seeker’s decision-making process, and therefore, it could be effectively used in conceptualising the JSVP. However, it is claimed that, in most cases, the job choice theory is not considered the basis for developing the construct of the JSVP. Therefore, taking the job choice theory into consideration, this paper aims to develop a framework for conceptualising the JSVP from a new perspective. Thus, through a systematic literature review, eight factors that explain the conceptual domain of the JSVP are discovered and, on the basis of them, eight propositions are made in developing a measurement scale for the JSVP. This study discusses the theoretical and practical implications of the proposed factor-based structure for the JSVP. Subsequently, the limitations in the present research are discussed, and suggestions are made for future research concerning JSVP constructs.
