Urban Youth Perspectives on AI-Driven Solutions for Food Waste Management: Evaluating the Smart Food Waste Accelerator Prototype in Colombo Zeron Anas, NJ; Asam, NJM As part of the Youth Leadership for Climate Action (YLCA) initiative, carried out by Biodiversity Sri Lanka (BSL) and funded by the British Council, this study aims to empower young leaders in climate action by tackling the critical issue of food waste management. Our community intervention involves creating an AI-led Smart Food Waste Accelerator prototype. The first phase of our study involved a baseline survey in the Dehiwala Municipal Council region, employing a mixed-methods approach using key informant interviews (KIIs) and structured questionnaires to gather data from youths aged 18 to 29 on their perspectives on food waste management. A total of 567 responses were collected, revealing significant concerns about the absence of proper food waste disposal methods, with 91% of respondents acknowledging it as a household issue. Alarmingly, 89.45% of participants indicated the lack of appropriate disposal methods, with over 93% relying on local government waste vehicles. Our findings showed an average daily accumulation of 0.67 kg of food waste per household, predominantly comprising meal leftovers. Importantly, 89% of respondents expressed a willingness to purchase the Smart Food Waste Accelerator for their homes, and 96% were eager to understand its features and market availability. The AI-driven solution in this prototype exemplifies the potential for innovative technology to transform food waste management, promoting sustainability and reducing environmental impact.

Revolutionizing Mobility: Exploring the Integration of Ridesharing and Parcel Delivery Applications Pabasara, BKT; Goonathilake, MAST; Wedisighe, N This research explores the use of mobile applications to address traffic congestion and environmental degradation caused by the increasing number of vehicles. The study focuses on ridesharing and parcel delivery services as potential solutions. By optimizing seat occupancy in private vehicles through ridesharing apps, the number of vehicles on the road can be reduced. These applications connect drivers and riders with similar routes, enabling shared rides and more efficient use of available space. Additionally, integrating parcel delivery services into these applications can further decrease vehicle usage and reduce delivery times. This study evaluates the critical factors for the success of such applications, including the number of seats utilized and key features that benefit both drivers and passengers. The goal is to provide insights into how mobile apps can contribute to a more sustainable and efficient transportation system.

Review of potential research and development areas in the technological aspect of Bioprinting Liyanarachchi, VW Bioprinting technology has shown a swift development within the last decade. However, the fundamental limitations of bioprinting technology still need to be addressed. This review aims to identify limitations, the rationale behind them, the current approaches to solve them, and propose novel methodologies to address these challenges. The data were collected from several databases, using different combinations of keywords in metadata to precisely identify the technological limitations and analysed in depth over the resulting collection of literature in several disciplines ranging from 3D bioprinting, 3D printing, Machine Learning, Stem cell technology, Cell biology and transplant medicine, and Biomaterials to identify the major limitations, current trends and deficits in the current approaches to overcome the existence of the fundamental limitations. From the analysis, the leading three 3D bioprinting technologies were identified, laying the foundation for all other bioprinting technologies. The fundamental limitations, novel approaches, and understandings were compiled. Also, the limitations across the entire bioprinting discipline were separately identified and compiled. Different approaches to solving the existing limitations were scrutinized and possible research avenues and directions were proposed. This understanding of limitations and the proposals may direct young scientists and biomedical engineers to solve them.

Review Of High-Capacity Battery Systems For Onboard War Ships In The Era Of Artificial Intelligence De Silva, LMH Battery technologies have ever been developing rapidly in the era of Artificial Intelligence for the marine transportation industry aiming for more greener energy for propulsion. Meanwhile the war ships also transforming from traditional propulsion to modern hybrid or pure electric propulsion, the potential for propulsion in battery electric and combination of batteries with a diesel powered & steam powered engine in a hybrid system will be used in modern ships. The battery technologies are developing rapidly to cater the future potential maritime propulsion applications. The propulsion & auxiliary systems onboard ship required to support the batteries with the technical characteristics of their weight, volume, and cost of a maritime battery systems. The energy demands & consumption pattern of military vessels for specific operations are considered while selecting the best energy production & storage facilities. The energy demands could be catered either by pure battery or by hybrid methods for propulsion & auxiliary requirements. The amount of load required to move in different environment conditions also considered while selecting the energy storage. This technical paper gives an insight overview of the available battery technologies and future developments in the industry that may potentially available for the future usage for propulsion & auxiliaries for future ship’s in the era of Artificial intelligence.
