Anvendelsesområder og sikkerhetsløsninger for RFID-teknologi i helsesektoren
2004
Masteroppgave i informasjons- og kommunikasjonsteknologi 2004 - Høgskolen i Agder, Grimstad Radio Frequency Identification (RFID) er en teknologi som inneholder mange muligheter, spesielt i sammenheng med annen mobil kommunikasjonsteknologi. Ved Sørlandet Sykehus HF i Arendal ønskes en øket identitetssikring og kvalitetskontroll på prøver som blir analysert ved laboratoriet. Det har derfor vært ønskelig å se på hvordan RFID-teknologien kan benyttes i sammenheng med rutiner for prøvetaking, og hvilke begrensninger og muligheter som ligger i lagring av sensitiv informasjon i RFID-brikker. På bakgrunn av observasjoner, intervjuer og oppfølgingsmøter med nøkkelpersoner ved sykehuset har det vær…
Overføring av prosessdata via WAP
2000
Masteroppgave i informasjons- og kommunikasjonsteknologi 2000 - Høgskolen i Agder, Grimstad Denne oppgaven ser på mulighetene for å overføre prosessdata via en WAP-telefon. Prosessdataen som skal overføres er et EKG-signal. EKG er et signal som beskriver forandringer i elektrisk aktivitet på hjertet. En WAP-telefon skal i denne oppgaven fungere som en alarm som en hjertepasient hele tiden har med seg. Dersom pasienten slår alarm, skal WAP-telefonen hente ut pasientens EKG fra en database og sende disse til en alarmsentral, der det skal være mulig og følge pasientens utvikling. Et EKG signal har en båndbredde fra 0-150 Hz. Det er mulig å kode dette signalet i forskjellige formater. Disse for…
Balanced scorecard as a strategic management tool : the case of Seagull AS
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad Can investments in IT help a company to achieve its overall strategy and vision? Research over several years has resulted in mixed findings but several studies shows that the IT investments actually can result in better performance for companies. To achieve this it is important to align the IT investments with the overall business strategy and vision. The aim of this thesis is to see how Porter’s theories on competitive strategy and Kaplan and Norton’s Balanced scorecard can help the company to specify an IT system for the Operations department. The main idea is that the IT investment will support th…
Evaluation of OSA API's for 3rd party developers of Telco-services
2002
Masteroppgave i informasjons- og kommunikasjonsteknologi 2002 - Høgskolen i Agder, Grimstad Changes in business models introduce new actors to the telecom business. A set of new demands occurs and to handle this, a technical enabler like OSA is needed. Telenor R&D, which often provides Telco services in research projects, must form an opinion concerning this framework. Thus an evaluation of OSA is inquired. This thesis presents an introduction and evaluations of the OSA framework, further, a closer look at two of the OSA API’s (User Status and Terminal Capabilities) are made. To enhance the evaluation, Youngster has been utilized as an example of where the OSA framework can be used. An impl…
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…
Non-contractual churn prediction using Hierarchical Temporal Memory
2018
Master's thesis Information- and communication technology IKT590 - University of Agder 2018 As markets become more saturated and industry leaders compete over the existing customer base, competitors look for ways to improve customer retention with their customers. It is considered much more expensive to gain a new customer than retaining one, so the industry leaders look for ways in which churn in a customer can be predicted and potentially be avoided by incentivizing the customer to stay. Several of the previously proposed approaches struggle with combining the linearity with the non-linearity that exist within churn analysis and prediction. This emphasizes the need for research into state…
Neuroevolution of Actively Controlled Virtual Characters
2017
Master's thesis Information- and communication technology IKT590 - University of Agder 2017 Physics-based character animation offer an attractive alternative to traditional animation techniques, however, physics-based approaches often struggle to incorporate active user control of these characters. This thesis suggests a different approach to the problem of actively controlled virtual characters. The proposed solution takes a neuroevolutionary approach, using HyperNEAT to evolve neural controllers for a simulated eight-legged character, a previously untested character morphology for this algorithm. Using these controllers this thesis aims to evaluate the robustness and responsiveness of a c…
Imitation Accelerated Q-learning on a Simulated Formula Student Driverless Racecar
2020
Master's thesis in Information- and communication technology (IKT590) In the international Formula Student competition, only a handful compete in the driverless category. Most of them using expensive hardware such as LIDAR’s. By leveraging reinforcement learning, a cheaper camera based system can be created .In order to train this system a simulator based on a fork of Microsoft’s AirSim by Formula Technion was used. A virtual replica of a Formula Student car designed for 2020 by Align Racing UiA, functioned as the test vehicle. In order to decrease the required training time, a pre-trained imitation learning network was used. This was implemented into a Deep Q-Learning network in four diffe…
