IoT-based Data Collection and Transmission for Thermal Water Supply Systems in a Smart Home: Implementation and Testing
2021
Master's thesis in Information- and communication technology (IKT590) This thesis will look into theoretical aspect, implementation and design of data collection and data communication systems. The core system that this thesis use as a data collection system is a thermal water system that exploit heat exchange from a well. Most problems that occur in heat transfer systems can be avoided by implement a automatic surveillance system. This thesis will review basic functionality of the intended thermal system and operative problems and further propose a surveillance system using theory in data collection and data transmission- To transfer the data collected from the thermal system a communicati…
FEST on FHIR : A Standardized Service Interface for Norwegian Medicines Registry
2018
Master's thesis Information- and communication technology IKT590 - University of Agder 2018 The Norwegian Electronic Prescription Support System (FEST) is a Norwegian drugs database in XML format offered by the Norwegian Medicines Agency (SLV). FEST includes all information about drugs that can be prescribed electronically in Norway. FEST is used as a pharmaceutical data source by practitioners, pharmaceutical companies, and hospitals. The Norwegian hospitals are divided into four health regions. Each region has its own drug registry, but they use FEST as a resource of drug information and take the responsibility of updating their own systems with the latest up-to-date version of FEST. Havi…
An Attention-Based Encoder-Decoder for Week-Ahead Sales Forecasts Applied to a Norwegian Zoo
2021
Master's thesis in Information- and communication technology (IKT590) Accurate sales forecasts are vital for companies to plan efficiently and make strategic economic decisions. However, predicting future sales is a complex problem due to the high variance and strong seasonality of sales data. Dyreparken is a zoo and water park in Norway that operates over 30 stores and restaurants throughout the two parks. Accurate automated sales forecasts can enable Dyreparken to more efficiently manage staffing by providing a more reliable decision basis. Such forecasting is challenging among others because there are significant differences between departments with varying activity levels, opening hours…

Estimation of temperature development in secondary substation transformers
2021
Master's thesis in Information- and communication technology (IKT590) The temperature in a transformer element has a great impact on the aging process fora transformer. After a pilot project that aimed to make their power grid smarter, Agder Energi had temperature-data from sensors placed on some of their transformers. The purpose of this thesis was to establish a method for estimating transformer temperature based on available information such as load, capacity, and external weather conditions. To succeed, we had to deal with limited data, that is, few relevant samples combined with high levels of noise. To address the challenges of the estimation problem and the limitations of the data, w…
The Maritime Pickup and Delivery Problem with Cost and Time Window Constraints : System Modeling and A* Based Solution
2019
Master's thesis Information- and communication technology IKT590 - University of Agder 2019 In the ship chartering business, more and more shipment ordersare based on pickup and delivery in an on-demand manner ratherthan conventional scheduled routines. In this situation, it is nec-essary to estimate and compare the cost of shipments in order todetermine the cheapest one for a certain order. For now, these cal-culations are based on static, empirical estimates and simplifications,and do not reflect the complexity of the real world. In this thesis,we study the Maritime Pickup and Delivery Problem with Cost andTime Window Constraints. We first formulate the problem mathe-matically, which is c…
Enabling Edge Computing In 5G Via Local Area Data Network : Implementation and Experiments
2019
Master's thesis Information- and communication technology IKT590 - University of Agder 2019 The benefits of cloud computing are eclipsing when compared to other technologies, but the applications of cloud computing are very much cloud computing also has limitations due to its centralized architecture. The centralized cloud computing architecture gives rise to unnecessary delays which result in poor user experience. To avoid this, a decentralized cloud computing concept was introduced. In this concept computing and storage part of the cloud was to be moved as close to the user equipment as possible. By doing so the overall delays can reduce significantly which will enhance user experience. T…
An Environment Adaptive Approach for Indoor Localization Using the Tsetlin Machine
2021
Master's thesis in Information- and communication technology (IKT590) Indoor positioning is a challenging task due to the small scale of area and the complex electromagnetic environment. Among different distance measurement schemes, Received Signal Strength Indication (RSSI) readings are commonly used in proximity and localization applications such as in BLE and Wi-Fi, because of the low power consumption and simplicity of retrieving this information. There are several approaches for RSSI based indoor localization, among which the deep-learning based models trained with fin-gerprinting data can achieve far superior localization accuracy compared with orthodox approaches, such as trilaterati…
Design and Implementation of Self-Powered Long Range IoT Device Based on LoRaWAN
2020
Master's thesis in Information- and communication technology (IKT590) This project proposes a self-powered long-range wireless sensor node based on Long Range Wide Area Network (LoRaWAN) with various sensing capabilities. The nodes have been designed in such a way that these are self-sustainable throughout the components’ lifespan. These are completely powered by ambient solar energy harvesting. Also, these nodes can be deployed on a large scale and are maintenance-free. In addition, these nodes can be deployed in remote places where the accessibility is limited, and maintenance is difficult. The wireless sensor nodes can be deployed both in indoor and outdoor environments with sufficient l…
Deep Hybrid Neural Networks on Multi-temporal Satellite Data: Predicting Farm-scale Crop Yields
2021
Master's thesis in Information- and communication technology (IKT590) Accurate farm-scale crop yield predictions can enable farmers to improve their yield per decare and inform subsequent sectors of the availability of grains sooner. Existing research on yield predictions is limited to regional analytics, which often fails to capture local yield variations influenced by farm management decisions and field conditions. Farm-scale crop yield predictions require precise ground-truth prediction targets, which are not always available. It takes substantial manual labor to create large and suitable datasets of high-resolution per-farm samples. This thesis introduces a hybrid multi-temporal deep ne…
