International Conference on Multidisciplinary Research (ICMR 2024) Eastern University, Sri Lanka, Tamil Nadu Teachers Education University, India, and ESN Publications, India xi MESSAGE FROM THE CHIEF GUEST Emeritus Professor Ranjith Senaratne, Chairman, National Science Foundation. Today, despite phenomenal advances and remarkable accomplishments in science and technology (S&T), conflicts, terror, violence, unrest and disquiet as well as inequalities and disparities are mounting in a world characterized by volatility, uncertainty, complexity and ambiguity. This world is becoming increasingly more chaotic, more insecure and more dangerous by the day. For instance, the world has to come to grips with a myriad of formidable challenges and threats such as climate change, poverty, loss of biodiversity, pandemics, natural hazards, high-tech terrorism, drug trafficking, arms trafficking, cybercrime and pollution and marine while nevertheless seizing the emerging opportunities for the benefit of humanity. In addition, with the advent of the free economy and globalization, there is unhindered flow of capital, services, goods and labour across the globe where markets are not constrained by national boundaries. For instance, Apple phone designed in the USA is assembled in China and made in 31 countries with over 785 suppliers. Therefore in a globalized environment, no country can be independent of or insulated from what is happening elsewhere; all countries have become
International Conference on Multidisciplinary Research (ICMR 2024) Eastern University, Sri Lanka, Tamil Nadu Teachers Education University, India, and ESN Publications, India xii interdependent and interconnected. This is amply evident from the current Russia-Ukraine war, which has affected not only Europe, but the whole world, in which countries are connected by innumerable supply chains and value chains that account for about 70% of international trade. Moreover, contemporary sustainable development challenges, like the global challenges referred to above, are complex, multi-faceted and multidimensional. Tackling them demands an interdisciplinary, transdisciplinary, multi-sectoral and transnational approach where cooperation between specialists with diverse backgrounds in both the natural and social sciences across territorial boundaries is imperative. Besides, there is growing recognition that new approaches and different types of expertise are needed to renew science. Under the circumstances, it is gratifying to note that the Eastern University, Sri Lanka (EUSL) has broken away from the conventional monodisciplinary approach to embrace a multi-disciplinary and interdisciplinary approach in addressing real-world issues through its research endeavours. It is my fervent hope that the EUSL will extend this approach to its academic programmes as well thereby introducing appropriate cross-faculty degree programmes to the higher education sector of the country. It will make the EUSL a trendsetter and a trail blazer in the higher education landscape of the country. I wish the endeavours of the EUSL in this regard be crowned with success. Emeritus Professor Ranjith Senaratne, Chairman, National Science Foundation.

Arunmaran ABSTRACT Consider a region Ω and a basepoint 0 in Ω. We are interested in where the Brownian particle released from a basepoint 0 first hits the boundary of the region Ω within a distance of 0. Evaluating these probabilities for each > 0, we define the special function ℎ() always expressed for a region with a specific location of the basepoint 0. We call this ℎ() as the ℎfunction. This function is non-decreasing, and takes the value between 0 and 1 including these two values, as ℎ() represents the probability that the first exit occurs on the boundary of Ω. To understand the relationships between the ℎ() and the shape of the region Ω. In this paper, we explain the ℎfunction of a doubly connected unbounded region Ω formed by deleting two horizontal line segments along the real axis from the right halfplane. In the computation of ℎ(), we use the prime functions which are the key tool to solve problems related with multiply connected regions. Also, here we use the Cayley-type maps which transform the concentric annulus onto the lower halfplane with a deleted line segment that emanates from the origin and lies in the lower halfplane. To compute ℎ() of region Ω with a chosen basepoint, we first seek a conformal map that transforms a concentric annulus onto the region Ω, then identify the suitable Cayley-type map, and formulate a potential function whose imaginary part is harmonic and produces the ℎ-function ℎ() of the region Ω.

Weerakoon 1,* and A.G. Johnpillai 1 ABSTRACT We study the existence of exact solutions for a nonlinear second-order ordinary differential equation arising as a mathematical model in epidemiology. The nonlinear equation admits eight-dimensional Lie algebra of point symmetries. We show how one can use the invariant of a Lie point symmetry generator of two-dimensional subalgebra to reduce the nonlinear equation to the Riccati equation. We further show that the reduced Riccati equation is linearizable to a second-order ordinary differential equation via the Riccati transformation. The exact solution of the nonlinear equation is then obtained by using the general solution of the linear second-order ordinary differential equation and the Riccati transformation. Moreover, we demonstrate that the Lie symmetry methods provide a systematic and effective approach for investigating the dynamics of the underlying nonlinear epidemiological model in a simpler manner via the obtained exact solution.

Sasni1,* and R. Yogeswary2 ABSTRACT Numerical integration plays a major important role in mathematics. In this study we introduce a new approach to estimate definite integrals. Our method involves using secant lines of the curve and is compared with already existing methods like Simpson’s rule, midpoint rule and trapezoid rule. Our primary purpose is to make these calculations more accurate, especially when the existing methods are challenging. Our approach is based on a simple idea: the area under a curve and its secant line. We developed a new model and also modified it using Taylor polynomial. We experimented our proposed model using algebraic, trigonometric, exponential function and consistently our method performed better than existing methods. Our experiments show that when increasing the intervals our model provides more accuracy. In summary, our study presents a new effective way to estimate definite integrals, offering improved accuracy compared to standard methods. By focusing on secant lines, we provide a innovative approach that proves beneficial across different types of mathematical functions. This contributes to better numerical integration techniques with applications in various mathematical scenarios.

Yanuprasath1*, M.C.M. Rifan1 , M.M. Nafeer1 , M.B.H.M. Rihan1 and H.C. Ganege1 ABSTRACT The world is focused on promoting the widespread use of Electrical Vehicles (EVs) in the transportation sector, aiming to reduce dependence on fossil fuels and minimize greenhouse gas emissions. With the development of EVs, Battery Swapping Stations (BSSs) and conventional battery charging stations are introduced to charge batteries as efficient means to supply power to EVs. Between those options, BSS is a more attractive method for users due to its capacity to charge batteries while minimizing the waiting time at charging stations. This research is concentrated on improving the BSSs designed for motorcycle batteries with 10 Ampere-hours (Ahs). The primary objective of this research is the design and implementation of a cost-effective BSS control system based on the Internet of Things (IoT). As an advancement of the system, the system is upgraded to function during power outages. The communication method has been improved to overcome the system malfunctions caused by signal losses or drops. Additionally, a method for storing and displaying historical data, including State of Charge (SOC) and State of Health (SOH), temperature, and battery percentage has been introduced. Moreover, the system has been enhanced the system with the web application, thereby further improving its capabilities. When enhancing the system, a Raspberry Pi-based control system has been introduced to reduce the cost and connection complexity of the system. Further, NodeMCU is employed to control the individual battery slots in BSS thereby
International Conference on Multidisciplinary Research (ICMR 2024) Eastern University, Sri Lanka, Tamil Nadu Teachers Education University, India, and ESN Publications, India 9 preventing whole system failures with a signal component malfunction. The Controller Area Network (CAN) module facilitates the transmission of data from the Battery Management System (BMS) to NodeMCU, and a Wi-Fi network is used to connect all data to the cloud-based application. To maintain all functionalities within the system during a power outage, an external power source is utilized and provides access to charged batteries within the BSS. Comprehensive battery details taken from BMS are regularly uploaded to the cloud and customer can access and view required details through a web application based on their requirements. Further, customers are provided with facilities such as the ability to pre-book batteries and checkout of available batteries with the charging percentages and historical data for each battery. As future implementations, BSS can be improved to provide equivalent batteries to customers by utilizing information from BMS, especially battery cycle data. Moreover, the BSS can be upgraded to establish a connection with the nearest BSS control system in the event of a malfunction in the existing station’s control system, ensuring uninterrupted service. In conclusion, the developed BSS control system significantly enhances overall system reliability by mitigating the risk of power and communication failures. Additionally, it provides a user-friendly platform for customers to optimize their functionalities and it contributes to promoting sustainable transportation through Electrical vehicles.

Bandara1 , W.A.M. Gunathilaka1 , S.H.T.D. Dharmadasa1 ,R.M.S.M. Rathanayake1, * , I.G.P.N. Karunasena2 and L. Wickramasinghe1 ABSTRACT With the global advancement, the use of Electric Vehicles (EVs) has become more prominent today. Since Li-ion batteries are used in most electric vehicles, this project was conducted based on Li-ion batteries. A Battery Management System (BMS) is required to monitor, safely, balance, and control the charging and discharging of a battery pack. Despite the variety of battery systems available, there are still several limitations that hinder the widespread adoption of EVs such as excessive cost, weight, space requirements and limited battery lifespan. The primary goal of this project is to develop an optimized BMS to improve the unique requirements of electric vehicles to accomplish high-power output, increase battery health and safety, measure the cycle count, and identify the destroyed batteries in the pack. Achieving this goal requires a comprehensive understanding of several factors that impact battery performance and a focus on developing an advanced BMS that can optimize the performance of the pack in real-time. The BMS was designed using the STM32 platform microcontroller unit (STM32F103CBT6TR), and battery monitoring integrated circuit (ML5238). When compared to existing systems, this BMS design includes unique features such as individual battery cycle counting methods, an improved temperature sensing mechanism, an improved voltage measuring procedure using an N-channel MOSFET, and balancing the BMS circuit using capacitors. Accordingly, this research is critical to the continued growth and success of the EV industry, as it can contribute to reduce unnecessary costs, improve efficiency, and enhance the overall performance of electric vehicles.

International Conference on Multidisciplinary Research (ICMR 2024) Eastern University, Sri Lanka, Tamil Nadu Teachers Education University, India, and ESN Publications, India 11 DESIGN AND MANUFACTURING OF A PROTOTYPE POLYTHENE RECYCLE MACHINE FOR PRODUCE A POLYMER SHEET K.G.K. Perera1 , K.P.C. Dilshan1 , V. Thushangan1 , H.L. Subasinghe1 and D.N. Liyanage1* ABSTRACT The growing issue of polythene waste poses a formidable environmental challenge and a global issue. Even though they are frequently employed, traditional techniques like landfilling and incineration are insufficient to handle the growing amount of polythene waste, which results in resource depletion and environmental degradation. By addressing the shortcomings of current waste management systems, the project seeks to pave the way for innovative approaches, including the development of a Polythene recycling machine. The main objective of the project is to design and manufacture a prototype polythene recycle machine to produce sustainable polymer through the seamless integration of an extruder machine, a pressuring machine, and a pressing machine. The proposed system integrates an extruder machine, a pressuring machine, and a pressing machine, each playing a distinctive role in the intricate process of transforming discarded polythene into resilient and eco-friendly materials. This thesis presents a holistic solution to the pressing issue of polythene waste, culminating in the design and manufacturing of a polythene recycling system for sustainable polymer sheet production. The proposed system orchestrates a transformative symphony, converting discarded polythene into resilient and eco-friendly materials. Commencing with the extruder machine, transforming polythene waste into a molten state, the journey progresses to the pressuring machine. This component subjects the molten polythene to controlled force and temperature, preparing it for the

International Conference on Multidisciplinary Research (ICMR 2024) Eastern University, Sri Lanka, Tamil Nadu Teachers Education University, India, and ESN Publications, India 13 RFID BASED VOTING SYSTEM TO IMPROVE THE ELECTION PROCESS AND TO AVOID RIGGING M.N.V. Fernando ABSTRACT Sri Lanka, being the oldest democracy in South Asia, is still using the old traditional paper-based election system. The major drawback of this process is the lack of efficiency in counting the votes, the printing cost, and the dependency on human resources. The main objective of this study is to replace the current paper-based election system with paperless electronic voting systems. Radio frequency identification (RFID) is a popular method for automatic identification and data capture that uses electromagnetic fields to automatically identify, and track tags attached to objects. The electronic voting machine is developed by using a microcontroller, an RFID reader, RFID tags, an LCD display, a buzzer alarm, LEDs, and voting push buttons. In this system, each registered voter will have a separate voter identity card with an RFID tag printed on it. During the election, the RFID reader module senses the RFID tags with voter ID. After receiving the voter ID from the RFID reader, the IC compares the ID, and if the data matches the already stored information, the information is displayed on the LCD display, and the voter is allowed to cast his vote. The admin panel has a different ID, and they have authority to see the results, reset the voting results, add a new registered user, remove a registered user, reset all users, and reset all results. If the voter is not authorized, then a message is displayed on the LCD display as “unknown user," and the buzzer alarm will ring to inform them that the person is not allowed to vote. LEDs and buzzers were used to indicate the vote cast and the scanning process of the card. The data stored in the EEPROM will remain even when the microcontroller is turned off. So, it
International Conference on Multidisciplinary Research (ICMR 2024) Eastern University, Sri Lanka, Tamil Nadu Teachers Education University, India, and ESN Publications, India 14 helps to improve the security of the device. The implementation of this system helps to minimize the possibility of rigging in elections, reduce the probability of causing human error, and eliminate the need to do manual work. Electronic voting systems have many advantages, such as being more efficient, reliable, cost-effective, producing faster and more accurate results, and being more environmentally friendly than traditional hand-counted paper ballots. Therefore, it will be a necessary replacement for the future of Sri Lankan democracy. There are some future scopes as the system can be implemented by interfacing an external memory for storing the votes to prevent loss of data even if the machine is damaged. Another improvement that can be made to this system is integrating fingerprint matching or a face recognition system, which improves the security of the election process. Alcohol and metal detectors can also be interfaced to the system so that an unhealthy environment will not be created. KEYWORDS: Electronic Voting Machine, RFID reader.

Perera1*, G.R.S. Jayasena1 , M.P. Sudheera1 , S. Brunthapan1 , Harshana Senavirathna1 and Ayomi Pabasara1 ABSTRACT Textile and cardboard waste is a huge threat to the environment and global industry. Among them, fast fashion waste is expected to reach 134 million tons annually and cardboard waste is approximately 146.1 million tons in landfills. This research was focused on applying the fabric and cardboard waste in a repurposed way according to the 5R waste management concepts. The construction industry is a well-desired industrial building and architecture branch with more sustainable and innovative approaches. Concrete curing is one of the construction procedures that significantly affects building strength. However, there is currently no effective method to determine the necessary water requirement during the concrete water curing process. Here an eco-curing system with a membrane was designed as an economical and environmentally friendly solution to the concrete curing process in the construction industry. Furthermore, natural rubber latex and Polyethylene Glycol Additive (E8000) have been identified as advanced solutions for bonding agents. Under the standard of ASTM C31 for concrete slabs, the designed membrane successfully achieved the required amount of water release for the concrete curing process of 19.594 ml per day. The membrane had dimensions of 15 × 15 cm squared and a thickness of 1 cm. The proposed eco-membrane system was manufactured by compressing two layers together under 75 N manually using a compressive mold in 24 hours. It included approximately 90 holes in the upper layer, each with a 1.5 mm diameter. As a result, this layer can prevent water evaporation to the environment and successfully control the water flow rate through the

Besides, the membrane was constructed using nontoxic and biodegradable materials. Hence, this membrane was completely focused on an effective solution for global and local fabric and cardboard waste, both scientifically and economically.

International Conference on Multidisciplinary Research (ICMR 2024) Eastern University, Sri Lanka, Tamil Nadu Teachers Education University, India, and ESN Publications, India 17 VIBRATION ABSORBERS TO PREVENT FAILURES CAUSED BY VIBRATIONS IN UAV MANUFACTURED BY SLAF D.A.M.N. Wijerathna1*, K.M.J.R. Karunarathne2 , V.V.S. Ranaweera3 , M.G.L. Ravishanka4 and V.H.P. Vitharana5 ABSTRACT The Sri Lanka Air Force (SLAF) manufactures unmanned aerial vehicles (UAV) by assembling various components to complete specific requirements without importing. During the UAV testing, several accidents have occurred. In the inquiries, the structure failure caused by the UAV's engine vibration forces was inferred to be the cycle time expected of the structure material. SLAF doesn’t identify the magnitude of vibrations acting on the surfaces, because there isn't a method of measuring the magnitude of shock for UAV. Due to the lack of effective vibration absorption between the engine and the structure, the direct transmission of engine shock forces to the structure is assumed to be the cause of failure. In this project, develop an Arduino-based coded system with relevant sensors used as the vibration measuring method for UAV, and introduce customized effective vibration absorbers. The system automatically plots on a graph that shows the current state magnitude of vibration forces. The advantage is that if a UAV experiences significant vibration of parts in fighting, immediate responses can be made to prevent the UAV from crashing and reduce the risk of unexpected damage to the environment and other property. Several vibrations-absorbing designs have been simulated in the software of Solidworks and Ansys. Among them, the Manufacturer selected the absorber design and installed the UAV. The data obtained with designed absorbers using gas springs show a reduction of 43.32% in the transmitted vibration forces than when using the rubber feet.

Farhan1, 2* and P. Samarasekara3 ABSTRACT Magnetic properties of bcc structured ferromagnetic thin films with two spin layers were described using the fourth order perturbed Heisenberg Hamiltonian with all seven magnetic energy parameters. Spin exchange interaction, magnetic dipole interaction, second and fourth order magnetic anisotropy constants, in and out of plane applied magnetic fields, demagnetization factor and stress induced anisotropy constant were considered in the model. 3D plot of total magnetic energy versus angle and spin exchange interaction were plotted using the different values of second and fourth order magnetic anisotropy constants. All other magnetic energy parameters were fixed at constant values. All the peaks are closely packed in the graphs plotted using the fourth order perturbed Heisenberg Hamiltonian compared to peaks in the graphs plotted using the second and third order perturbed Heisenberg Hamiltonian. In this manuscript, the order of magnetic energy was found in the range of 1035 to 1041. The order of magnetic energy slightly changes when the values of fourth order anisotropy constants of two spin layers are interchanged. The higher order magnetic energy was observed, when the second order magnetic anisotropy of both the bottom and top spin layers are increased. In addition, the graphs of energy versus angle were plotted to find the magnetic easy and hard directions. The angle between magnetic easy and hard direction is not 90 degrees in all the cases.

International Conference on Multidisciplinary Research (ICMR 2024) Eastern University, Sri Lanka, Tamil Nadu Teachers Education University, India, and ESN Publications, India 19 A REVIEW OF HOLISTIC AND SUSTAINABLE BIOPOLYMERS IN COMPARISON TO SYNTHETIC POLYMERS P.V.N.M. Kaushik1,* , N. Krishna Jyothi2,* and M. Gnana Kiran3 ABSTRACT The world currently is drifting from an economy that is driven by fossilfuel-energy, to a more renewable and sustainable economy. Recent studies in the field of material science reveal that the interest in the manufacturing of materials has shifted towards the use of polymers and fibres. Though there was an initial urge to synthesize synthetic polymers, the world soon witnessed the hazards of these. Hence, the choice of the use of a biodegradable matrix was worth considering, as, this immediately results in a completely biodegradable polymer composite, which not only is ecofriendly, but also efficient. Polymers have found their application in various fields including the food and packaging industry, and the synthesis of artificial muscles in modern-day society, there is a tremendous urge to use synthetic polymers and their matrices for storage devices. Agobi et al. have reported the choice of conducting polymers for the usage of supercapacitors and batteries. Therefore, the choice of using biodegradable polymers for storage and energy devices is the current interest of study. The tamarind Seed Polysaccharide (TSP) polymer is blended with sodiumbased salt and the polymer electrolyte films are synthesized by the solution casting technique. The obtained biopolymer films have been subjected to XRD and FTIR characterization techniques to investigate the structural and chemical correlation between the chosen biopolymer and the salt. The AC impedance measurements have enabled the calculation of the conductivity of these polymer films. It was observed that the conductivity measured in
