Multi-purpose embedded communication gateway : system design and testbed implementation
2014
Masteroppgave i Informasjons- og kommunikasjonsteknologi IKT590 Universitetet i Agder 2014 This dissertation revolves around developing a multi-purpose embedded communication gateway. The gateway is equipped with multiple communication interfaces including Ethernet, Bluetooth, WiFi, Zigbee, LTE, and it can be configured and utilized for many purposes, such as a failover of an Ethernet cable via 4G in order to maintain the network connectivity. Raspberry Pi circuit board and the operating system Raspbian are selected as the hardware and the software platforms respectively. Different communication interfaces are coordinated by the Raspberry Pi and are configured via Linux scripts according to…
Seamless Hand-over Algorithm for Wireless Enterprise Networks
2007
Masteroppgave i informasjons- og kommunikasjonsteknologi 2007 – Høgskolen i Agder, Grimstad The mass deployment of the Institute of Electrical and Electronics Engineers’ (IEEE) 802.11 based wireless local area networks (WLAN) and increased sales in hand-held devices supporting WLAN have resulted in an urgent need to support fast WLAN handovers or roaming. The reason for this problem arising now is that hand-held devices are more mobile than a laptop and their users actively use their hand-held equipment while moving. Laptop users are often called nomadic users in contrast to the real mobile users. The customarily solution is that when a connection is lost with the associated access point, o…
OpenIMS and Interoperability with Asterisk/Sip Express VOIP Enterprise Solutions
2007
Masteroppgave i informasjons- og kommunikasjonsteknologi 2007 – Høgskolen i Agder, Grimstad Nowadays, with the development of the next-generation network, IMS becomes very important, and it will play a key role in the future All-IP infrastructure. But it is still in the developing stage, and it will take time for all 3G mobile networks upgrade to 3GPP networks. Therefore, the research project will study the interoperability solutions between Open Source IMS and Open Source VoIP/SIP implementations. This project is supported by auSystems and HiA. OpenIMS (Open Source IMS) was developed by FOKUS (a Germany institution) in December 2006. It is a free IMS enterprise solution. As it is so new, t…
Handling of IP-Addresses in the Context of Remote Access
2008
Masteroppgave i informasjons- og kommunikasjonsteknologi 2008 – Universitetet i Agder, Grimstad For various reasons (e.g., security, lack of IPv4-addresses) the services in the home smart space only use private IP addresses. This is unfortunate in the remote service access since these addresses frequently appear in responses sent from a service in the remote smart space (e.g., your home) to the visited smart space (e.g., your friend’s home).The Internet Engineering Task Force (IETF) provides some solutions and workarounds for the problem caused by NAT. In this project, the challenge to me is to summarize the available options, rank the options according to which one is preferred for the RA-…
Deep Convolutional Neural Networks for Semantic Segmentation of Multi-Band Satellite Images
2018
Master's thesis Information- and communication technology IKT590 - University of Agder 2018 Semantic segmentation of images is of increasing interest in the eld of computer vision and machine learning. Accurate and e cient segmentation methods is required for many of todays modern applications. This the- sis provides a review of deep learning methods for semantic segmentation of satellite images. Firstly, we compare di erent state-of-the-art methods. Next, we explore the bene ts of using multiple spectral bands of data as compared to the traditional RGB bands. Finally, a look at future possibil- ities with segmentation using capsule networks.
Combining Deep Privacy with an Attribute-driven Generative Adversarial Network to Preserve Gender and Age in De-identified CCTV Footage
2021
Master's thesis in Information- and communication technology (IKT590) A surveillance camera is an efficient solution to prohibit crimes for both small and big businesses, and is broadly utilized in big cities. Today, the police force can only access the camera footage for further investigation after an act of crime. In order to observe, find patterns, and react appropriately to an event, the Oslo Police wants to use its own CCTV cameras and analyze such footage in real-time. To investigate real-time CCTV footage and share such footage with a third-party for analyzing, the people in the footage need to be de-identified. In this thesis, we focus on de-identification of CCTV footage, preservin…
Hand Gestures Recognition using Thermal Images
2021
Master's thesis in Information- and communication technology (IKT590) Hand gesture recognition is important in a variety of applications, including medical systems and assistive technologies, human-computer interaction, human-robot interaction, industrial automation, virtual environment control, sign language translation, crisis and disaster management, en-tertainment and computer games, and robotics. RGB cameras are usually used for most of these applications. However, their performance is limited especially in low-light conditions. It is challenging to accurately classify the hand gestures in dark conditions. In this thesis, we propose the robust hand gestures recognition based on high re…
SNOMED on FHIR Transmission of clinical data with the Fast Healthcare Interoperability Resources protocol (HL7-FHIR) utilizing Systematized Nomenclat…
2019
Master's thesis Information- and communication technology IKT590 - University of Agder 2019 The exchange of information at the level of semantic interoperability needs some infor-mation model and clinical terminology work together. Electronic records of the patientmust include the terminologies in order to give the decision support to the practitionerwhen needed. Due to the lack of common standards for data structure and data sharingcreates the problem to interact and share information with different applications.Our main goal in this thesis is transferring the SNOMED-CT (Systematized Nomenclatureof Medicine Clinical Terms) terminologies using HL7 FHIR (Fast Healthcare Interoper-ability Res…
Is a SPARQL endpoint a good way to manage nursing documentation
2014
Masteroppgave i Informasjons- og kommunikasjonsteknologi IKT590 Universitetet i Agder 2014 In Semantic Web there are different technologies available, among these technologies ontologies are considered a basic technology to promote semantic management and activities. An ontology is capable to exhibits a common, shareable and reusable view of a specific application domain, and they give meaning to information structures that are exchanged by information systems [63]. In this project our main goal is to develop an application that helps to store and manage the patient related clinical data. For this reason first we made an ontology, in ontology we add some patient related records. After that …
Playing the game of Hex with theTsetlin Machine and tree search
2020
Master's thesis in Information- and communication technology (IKT590) Hex is an abstract mathematical board game where the players aim to build a connection of pieces, traversing the board from edge to edge. The game requires the use of certain patterns to be played at a high level. Artificially Intelligent Hex players have had success using Monte Carlo tree search and current research efforts have introduced neural networks. This thesis looks into the recent Tsetlin Machine pattern-recognition technique, relying on interpretability, in combination with the Monte Carlo tree search method to play the game of Hex. A supervised learning approach has been employed in an effort to teach the Tset…
