    Machine Learning to Aid in the Process of Disease Detection and Management in Soilless Farming
    (IEEE, 2022-07-18) Fernando, S. D; Gamage, A; De Silva, D. H
    This research aims at enhancing the methods and techniques that are being used in disease detection when it comes to soilless farming. Soilless farming is quite famous among the Sri Lankan farmers farming in urban areas. A mobile application is launched by us and this application is capable of identifying diseases in plants, therefore, farmers do not have to rely on their years of experience to identify the diseases. A novice farmer may struggle to say what is wrong with their plants, while another farmer with many years of experience may say what the disease is with no hesitation. Both those types of farmers benefit from our mobile application equally. The said mobile application consists of four components and each of them focuses on a different service. One of those components is to detect and manage diseases in plant leaves and that component is what this research paper showcases. This particular component allows the user to capture live-images of plant leaves. Then the application processes the captured image to identify if the plant is suffering from a disease. After that, it generates a report with a set of treatments. It further analyses and alerts the user if this disease detected is going to affect the harvest.

    Analyzing transport layer protocols to create an API to satisfy timed response in dynamic requirements of wireless networks
    (IEEE, 2014-12-11) De Silva, D. H; Ahamed Ishak, M. M; De Silva, G. C. M; Suranjith, A. V. S; Herath, H. M. H. S
    In modern systems it is very vital to have an efficient data transmission mechanism. This becomes more critical factor when it is involved with a system like a way finding application for vision impaired people or a medical system that notifies the doctor's smartphone when the patient's heart rate goes down. The size of the data that is used frequently by the mentioned systems is relatively small. Additionally it might take more time for connection establishment despite of the requirement of urgency. Thus this kind of data transmission is not ideal for such systems. Therefore this diversity of data transmission makes a special category of systems that needs a reliable, efficient data transfer mechanism since requirements of those systems such as low latency, reliability are not being fully satisfied by the current Transport Layer Protocol (TLP) selection mechanism.

    An investigation into dynamic TLPs for smartphone communication: To facilitate timed response in way finding for vision impaired people
    (IEEE, 2013-12-11) De Silva, D. H; Murray, I
    A reliable, high speed and efficient data transfer method is a very important factor in real time Way-finding systems since it requires information with very low latency to discover paths, avoid dangerous situations, identified changes in existing maps and alternative routes. This research will develop models and methods to facilitate bounded timing with minimal latency for way-finding application for vision impaired people. As a result of analyzing the requirements for Way-finding applications, it was noted that some typical behaviours involve relatively small amount of data transfer through networks. Existing Transport Layer Protocols (TLP) are not ideal for providing such requirements. This research investigates existing TLPs and proposes modifications / extensions to facilitate demands in Way-finding applications and will implement the Dynamic TLP to incorporate both reliable data transfers with high efficiency as well as frequent data transfers which do not require reliability.
