Development of an effective communication skill development program embedded in engineering study Program
(2009) Ranaweera, RAMP; Kahangamage, UP
This paper presents a successful and innovative approach for improving presentation skills of undergraduates by incorporating PowerPoint presentation to laboratory practical assessments. The key aims were to improve oral presentation skills, to enhance the knowledge of undergraduates about the state of the art technologies and to improve the effectiveness of laboratory practical assessments. After completion of the first "presentation coursework" session, a noteworthy improvement in presentation skills and enthusiasm among undergraduates for making presentations was clearly seen.

Development of an empirical model of a helically coiled steam generator for waste heat recovery
(2011) Premalhilake, MRLT; Rajapaksha, RPAKS; Hewa Bettage, MS; Perera, KKCK; Perera, PABAR; Ranaweera, RAMP
Discussions are going on today in many forums analyzing correlations between engineering applications and environmental pollutions. As a result of that, novel concepts such as green engineering have appeared in the engineering scenario. This paper describes a procedure developed for designing a helically coiled steam generator (SG) for recovering heat from the flue gas of a furnace. The design was applied to the lead melting furnace operating at Associated Battery Manufacturers (Ceylon) Ltd (ABM), Ratmalana, Sri Lanka, Most available literature deals with experimental investigations regarding correlations for heat transfer coefficients and pressure drops in helically coiled heat exchangers for both single phase and two phase flow regions. The paper presents a systematic procedure for designing a helically coiled SG through this case study.

Enhancement of students' learning experience through introduction of innovative methods of conducting and assessing laboratory classes: a case study
(2009) Ranaweera, RAMP; Gamage, JR; Kahangamage, UP; Dassanayake, VPC
This paper elaborates a successful attempt made for improved way of conducting and assessing of laboratory classes. The key aims were to improve the quality & effectiveness of laboratory classes, promote team work and increase relevance of the undergraduate practical programme that suits the industrial environment. In the design stage, problems of the existing methods, industrial requirements and expert views were carefully analysed. Finally it shown considerable improvement in quality and effectiveness of the practical programme and team working ability students.

Identifying the safe and efficient way of removing Lead acid battery terminals from battery cap for recycling Lead
(2011) Dassanayake, DEG; Mendis, MBRD; Patabandige, MPVYM; Ranaweera, RAMP
A significant portion of the Lead requirement for manufacturing Lead acid batteries in Associated Battery Manufacturers (Ceylon) Limited, the only battery manufacturer in Sri Lanka, is taken from recycling old batteries. At the moment the primary separation of Lead parts from the other parts of the battery is done manually. Thus this process suffers from the unavailability of skilled labors to remove battery terminals as the removal of terminals from the battery cap is the most difficult part done manually. Besides, the health risk to the operators is also quite significant. Therefore, a Semi- Automatic Battery Terminal Removing Machine was developed to overcome the above issues. This paper describes the experimental process of identifying optimum methodfor above process.
