Marine technologies' control networks analysis and optimization for failsafe operations examined for class certification
2014
Masteroppgave i Informasjons- og kommunikasjonsteknologi IKT590 Universitetet i Agder 2014 This thesis presents a suggested solution to improve Marine Technologies (MT) bridgesystems. MT is advancing their technology and use Ethernet as a base. This is new in theoffshore world and certification companies have yet to create clear lines to certify thesenetwork systems. Systems continue to get approved with their current protection, butmeasurements are needed to advance their protection and comply with new demands. Thethesis will go through their current demands and interpret them to optimize MT’s systems andgive the certification companies a clear line to follow. The thesis will analyze MT’s …
Naive Bayes classier-based fire detection using smartphone sensors
2014
Masteroppgave i Informasjons- og kommunikasjonsteknologi IKT590 Universitetet i Agder 2014 For many years, smoke detectors have been used as the most crucial _re detection sensors.Although smoke detectors do their job very well, they are not perfect and may causefalse or late alarms. This is because they only rely on one of the _re signs which is smoke.Fire has many other signs as well such as heat and light. It also a_ects its environmentalparameters such as temperature and humidity. But typically, buildings are not equippedwith sensors capable of sensing these changes. Recently, a few smartphone manufacturershave added temperature, humidity, and barometer sensors to their products which c…
Ontology-based personalized system to support patients at home
2014
Masteroppgave i Informasjons- og kommunikasjonsteknologi IKT590 Universitetet i Agder 2014 Chronic diseases are incurable diseases that require long term supervision and treatments by medical professionals. The most common chronic diseases are cardiovascular disease, obesity, diabetes respiratory diseases and cancer. With information and communication technology many applications have been implemented to facilitate different clinical decision making process. With new technology, personalized healthcare systems are in place to enable patients with chronic diseases to acquire continuous and long-term medical services at home. This improves healthcare delivery since medical services can be acc…
Position technologies for internet connected mobile terminals, offering location based audio services
2007
Masteroppgave i informasjons- og kommunikasjonsteknologi 2007 – Høgskolen i Agder, Grimstad The company Infotain wishes to offer location based audio guiding at museums. They wish that this audio is going to be available through the visitor’s mobile phone. However, to be able to offer location based audio guiding a suitable positioning technology for mobile phones has to be found. Therefore the purpose of this thesis is to gather information about the technologies that can be used for location based information. After the technologies have been thoroughly examined we have to give Infotain a recommendation about what technology seems to best satisfy the demands. Important factors in evaluati…
Performance Analysis of Super-Orthogonal Space-Time Trellis Coded MIMO-OFDM Systems over the One-Ring Channel
2007
Masteroppgave i informasjons- og kommunikasjonsteknologi 2007 – Høgskolen i Agder, Grimstad With the rapid development of wireless communications, the available bandwidth for wireless applications becomes more and more insufficient. Therefore, how to improve data rate without expending bandwidth becomes a main goal in modern communication system design. Recently, two wireless communication schemes, which can be used to effectively combat with multi-path fading, are widely investigated around the world. One is the multiple-input multiple-output (MIMO) technology and another is the orthogonal frequency division multiplexing (OFDM). As a result, a combined system, MIMO-OFDM, can be used for wi…
Mobilteknologi til videokommunikasjon ved trygghetsalarmer
2007
Masteroppgave i informasjons- og kommunikasjonsteknologi 2007 – Høgskolen i Agder, Grimstad Denne rapporten behandler bruk av mobiltelefoner som alarmsentral for hjemmeboende brukere. Studien legger vekt på de forskjellige mobile netts egenskaper og begrensninger som alarmbefordrer. Ønske om videotelefoni som alarm behandles og det foreslås løsninger for å ivareta dette uten å gå på akkord med sikkerhet. Juridiske sider med alarmer og videobilder behandles ut fra to ulike scenario avhengig av om hjelpere er offentlige eller private. Studien er gitt som en del av interregIII prosjektet Grensebroen Arena sin satsning innen emnet “Et år til hjemme” rettet mot eldre hjemme- boende. Prosjektet h…
Implementering av internettbasert pasientjournal i en helseinstitusjon
2007
Masteroppgave i informasjons- og kommunikasjonsteknologi 2007 – Høgskolen i Agder, Grimstad Det utvikles stadig flere internettjenester som gir nye og bedre muligheter for kommunikasjon og utveksling av informasjon. Det norske helsevesen har merket en stor etterspørsel fra pasienter og helsepersonell etter internettbaserte helseløsninger som vil forenkle hverdagen. De første internettbaserte helsetjenestene eksisterer, men disse er helt i startfasen og det er nærmest uendelige muligheter for hva slags tjenester en skal kunne tilby i fremtiden. Sårbarhetene relatert til internett og det strenge lovverket i Norge gjør slike tjenester vanskelig å gjennomføre. Løsningene som skal tilby slike tj…
A Deep Learning-based approach for Fault Detection of Power Lines
2020
Master's thesis in Information- and communication technology (IKT590) A transmission network is the most crucial part of modern infrastructure. However, it requires an extensive amount of power line inspection each year to maintain, and with an increased interest in replacing large helicopters with drones for this process, the possibility of including AI is equally compelling. This thesis goes into the second part by taking a deep learning-based approach in the interest of fault detection. A literature review illustrates that earlier research has some to none understanding of the complexity re-quired for inspection. Due to the advancement in object detection and classification, this thesis …
Differentiating Between Spontaneous and Posed Facial Expression using Inception V4
2018
Master's thesis Information- and communication technology IKT590 - University of Agder 2018 This thesis proposes a way to simplify and make solutions for spontaneous and posed facial expression analysis more efficient. Traditional approaches have been using hand-crafted features and two image frames to be able to differentiate between spontaneous and posed facial expressions. The solution aims to be as flexible as possible and introduces two models to differentiate between posed and spontaneous facial expression. We introduce Inception V4 as an algorithm to solve this task. The results indicate that Inception V4 may be too deep and unable to differentiate between spontaneous and posed facia…
Classification of GNSS Jammers using Machine Learning : Multivariate Time Series and Image Classification Based Approaches
2021
Master's thesis in Information- and communication technology (IKT590) GNSS is one of the most widely used positioning techniques in modern technology. However, the signals from the GNSS satellites are weak on earth due to the propagation attenuation, making GNSS-based systems vulnerable to interference or jamming of signals. This the-sis proposes a machine learning approach to detect the presence of jammers in the GNSS spectrum bands in recorded data. We have employed the state-of-the-art and baseline machine learning techniques for Image- and multivariate time series classification and evaluated their ability to classify the presence of illegal jammer activity. In addition, we propose a no…
