    Road Navigation System Using Automatic Speech Recognition (ASR) And Natural Language Processing (NLP)
    (IEEE, 2019-01-31) Withanage, P; Liyanage, T; Deeyakaduwe, N; Dias, E; Thelijjagoda, S
    In a highly evolving technical era, Voice-based Navigation Systems play a major role to bridge the gap between human and machine. To overcome the difficulty in taking and understanding user's voice commands, simulating the natural language, process the route with user's turn by turn directions while mentioning key entities like street names, landmarks, point of interests, junctions and map the route in an interactive interface, we propose a user-centric roadmap navigation mobile application called “Direct Me”. The approach of generating the user preferred route, system will first convert the audio streams into text through Automatic Speech Recognizer (ASR) using Pocket Sphinx Library, followed by Natural Language Processing (NLP) by utilizing Stanford CoreNLP Framework to retrieve the navigation-associated information and process the route in the Map using Google Map API upon the user request. This system is used to provide an efficient approach to translate natural language directions to a machine-understandable format and will benefit the development of voice-based navigation-oriented humanmachine interface.

    Critical Analysis on Identifying the Effect of Military Training Simulations on Confidence Level of Soldiers
    (2014-08-21) Fernando, S; Thelijjagoda, S
    Simulations and games grow very rapidly and dynamically with technologies evolving every day. Technologies of military simulation are continuously evaluated and upgraded since it is a key factor for military training, analysis, planning, etc. The training simulations had been used to train soldiers for a long time period, but systematic analysis haven't been made to identify if the military simulations have been able to achieve increasing the confidence level of soldiers,. There have been many researches on military training simulations time to time around the world. Mainly defence research centers had done researches to identify the areas to improve in order to upgrade the quality of training. These have been used to train soldiers' way back in the World War II. In the advancement of technology these have become more and more advance and effective on achieving their goals. DARPA (Defence Advance Research Program Agency) and the US Army research institute were the major two researchers on this domain. This paper presents a research that was conducted to identify whether military training simulations make an effect on the confidence level of the soldiers when they are battling. The objective of this research was achieved through evaluating the existing background of military simulations against the confidence level of soldiers, investigating how military training is done in terms of simulations, evaluating how simulation based training are effective for soldiers, identifying the factors that affect the confidence level of soldier and introducing a model to evaluate the confidence level of soldiers. According to the conceptual model used, actual experience, experience of others, self-efficacy, mission readiness, persuasion and emotional arousal were identified as factors affecting the confidence level of a soldier. Based on the collected data, the conceptual model which was proposed to measure the confidence level of soldiers could be justified to acceptable level.

    D-REHABIA: A Drug Addiction Recovery Through Mobile Based Application
    (SLIIT, 2016-04-06) Somasiri, L. U; Galabada, S. S. G; Wijethunga, H. M; Dayananda, H. M; Nugaliyadde, A; Thelijjagoda, S; Rajasuriya, M
    Drug addiction has become a major issue in the world. There are certain governmental and nongovernmental organizations which provide various programs to prevent, recover and rehabilitate drug addicts. The patients who are in the recovery process have a higher tendency of relapsing after being released to the society. The objective of this research is to produce a mobile based Drug Recovery Application and prevent patients from relapsing during the recovery process and to involve both family and rehabilitation center to the recovery of the patient. In order to accomplish this objective, the application contains an artificial intelligent assistant which will guide/help the patient regarding issues occurred during the recovery process, a location tracking mechanism to identify the movements of the patient and possible high risk places where drugs can circulate, a voice analysis mechanism to analyze the voice of the patient and identify emotional states which might cause the patient to relapse and treatments to reduce the stress, anxiety and depression level of the patient. The field of drug rehabilitation has been barely addressed via a proper technological solution, hence the system implemented as the result of this research can be effectively used for the recovery of the patient.

    Simplifying Law Statements Using Natural Language Processing
    (SLIIT, 2016-11-16) Dharmasiri, N; Gunathilake, B; Pathirana, u; Senevirathne, S; Nugaliyadde, A; Thelijjagoda, S
    Understanding the law statements for general public is evidently complex. The research derives a computational solution on reducing the complexity of the law statements. Given a law statement, the research will use both wordnet and “LawNet” to create a simpler meaning. The research will focus on information extraction, information retrieval, question analysis and answer generation techniques to derive better meaning of law statements. The law statement will be treated as a question and the “LawNet” and wordnet will be used in as information extraction points. The law statement will be analyzed as a question; more information will be retrieved through the wordnet and “LawNet”. This process mostly acts similar to a search engine’s process. The results provide on average 80% accuracy for a 1500 dataset.

    Dia-Shoe: A Smart Diabetic Shoe to Monitor and Prevent Diabetic Foot Ulcers
    (IEEE, 2019-12-05) Kularathne, N; Wijayathilaka, U; Kottawaththa, N; Hewakoralage, S; Thelijjagoda, S
    Diabetes is a continuous, lifetime disease that affects the body ability to use the energy found in food. Usually, the body splits down the sugars and carbohydrates you eat into a sugar called glucose. Glucose fuels the cells in the body. But the cells require insulin, a hormone, in the bloodstream to get in the glucose and utilize it for energy. Body doesn't make enough insulin, or it can't use the insulin it produces are the two main reasons to occur diabetes. Since the cells can't take in the glucose, it forms up in the blood. High levels of blood glucose can ultimately create nerve injury to the tissues in the extremities. The damage to nerves is a significant reason to occur foot ulcers. If a diabetic sufferer has foot ulcers, he/she need to manage it. Unless with the time they can drop their sensation in the foot which is known as neuropathy situation, which eventually appears in foot ulcers. Because of this, doctors advise using a diabetic shoe to prevent foot ulcers. These shoes decrease the peak plantar force exerted on the foot, but temperature, humidity and abnormal pressure are not managed, and this can be effective on the infection of wounds. As Diabetes is the main reason for the occurrence of these foot ulcers, maintaining blood glucose level is important. Diabetic patients can manage their blood glucose level by controlling daily calorie consumption and activities. For this self-maintenance of diabetes, patients should reduce their blood glucose level periodically and get notified of its divergence. The concept “Día shoe” proposed is an innovative mobile base plug and play device which can be attached to any sort of diabetic shoe to manage the foot ulcers and prevent them from spoiling, while monitoring temperature, humidity, weight and step count of the patient through a mobile application.
