Frame based signal representation and compression
(Dr. ingeniøravhandling, 0809-103X; 2000:65, Doctoral thesis, 2000)The demand for efficient communication and data storage is continuously increasing and signal representation and compression are important factors in digital communication and storage systems. This work deals with Frame ... -
Fully automatic real-time ejection fraction and MAPSE measurements in 2D echocardiography using deep neural networks
(Journal article; Peer reviewed, 2018)Cardiac ultrasound measurements such as left ventricular volume, ejection fraction (EF) and mitral annular plane systolic excursion (MAPSE) are time consuming and highly observer dependent. In this work, we investigate if ... -
Guidelines for limiting exposure to electromagnetic fields (100 kHz to 300 GHz)
(Peer reviewed; Journal article, 2020)Radiofrequency electromagnetic fields (EMFs) are used to enable a number of modern devices, including mobile telecommunications infrastructure and phones, Wi-Fi, and Bluetooth. As radiofrequency EMFs at sufficiently high ... -
Hardware-accelerated analysis of non-protein-coding RNAs
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:196, Doctoral thesis, 2005)A tremendous amount of genomic sequence data of relatively high quality has become publicly available due to the human genome sequencing projects that were completed a few years ago. Despite considerable efforts, we do not ... -
Hochschild cohomology, complexity and support varieties
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:234, Doctoral thesis, 2006)This PhD-thesis consists of the five papers - On the Hochschild (co)homology of quantum exterior algebras, to appear in Comm. Algebra, -Complexity and periodicity, Coll. Math. 104 (2006), no. 2, 169-191, -Twisted support ... -
Implementing Hydropower Scheduling in a European Expansion Planning Model
(Journal article; Peer reviewed, 2014)A method for implementing an enhanced hydropower planning formulation in a long-term expansion planning model is proposed. The methodological framework involves assigning hydropower generation a marginal cost through water ... -
Improved Receivers for Digital High Frequency Communications: Iterative Channel Estimation, Equalization, and Decoding (Adaptive Turbo Equalization)
(Dr. ingeniøravhandling, 0809-103X; 2002:128, Doctoral thesis, 2002)We address the problem of improving the throughput and the availability of digital communications in the High Frequency (HF, 3-30 MHz) band. In standardized military waveforms, the data is protected by an error-correcting ... -
Inclusion of women to ICT engineering–lessons learned
(Peer reviewed; Journal article, 2021)This paper address how we may understand inclusion strategies designed to reduce the gender gap in higher education in engineering and ICT engineering in particular. Based on a case study of a long-term inclusion effort ... -
Incremental Evolutionary Methods for Automatic Programming of Robot Controllers
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:228, Doctoral thesis, 2007)The aim of the main work in the thesis is to investigate Incremental Evolution methods for designing a suitable behavior arbitration mechanism for behavior-based (BB) robot controllers for autonomous mobile robots performing ... -
Interactive Process Models
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:2, Doctoral thesis, 2004)Contemporary business process systems are built to automate routine procedures. Automation demands well-understood domains, repetitive processes, clear organisational roles, an established terminology, and predefined plans. ... -
Joint Source-channel Coding: Development of Methods and Utilization in Image Communications
(Dr. ingeniøravhandling, 0809-103X; 2001:76, Doctoral thesis, 2001)In a traditional communication system, the coding process is divided into source coding and channel coding. Source coding is the process of compressing the source signal, and channel coding is the process of error protection. ... -
