Object Based Concurrency for Data Parallel Applications: Programmability and Effectiveness
(Dr.ingeniøravhandling, 0809-103X; 2002:83, Doctoral thesis, 2002)Increased programmability for concurrent applications in distributed systems requires automatic support for some of the concurrent computing aspects. These are: the decomposition of a program into parallel threads, the ... -
On Capacity and Delay of Multichannel Wireless Networks With Infrastructure Support
(Journal article; Peer reviewed, 2017)In this paper, we propose a novel multi-channel network with infrastructure support, called an MC-IS network,which has not been studied in the literature. To the best of our knowledge, we are the first to study such an ... -
On the performance and energy efficiency of the PGAS programming model on multicore architectures
(Chapter; Conference object; Peer reviewed, 2016)Using large-scale multicore systems to get the maximum performance and energy efficiency with manageable programmability is a major challenge. The partitioned global address space (PGAS) programming model enhances ... -
On the Theory of Shannon-Kotel'nikov Mappings in Joint Source-Channel Coding
(Doctoral Theses at NTNU, 1503-8181; 185, Doctoral thesis, 2008)In this thesis an approach to joint source-channel coding using direct source to channel mappings is studied. The system studied communicates i.i.d. Gaussian sources on a point-to-point Gaussian memoryless channel with ... -
Onset of Convection in a Triangular Porous Prism with Robin-Type Thermal Wall Condition
(Journal article; Peer reviewed, 2019)This paper investigates a peculiar case of thermal convection in a vertical porous prism with impermeable and partially conducting walls. We facilitate the analysis in the numerical finite-element environment alongside ... -
OntoLog: Flexible Management of Semantic Video Content Annotations
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:161, Doctoral thesis, 2005)To encode, query and present the semantic content of digital video precisely and flexibly is very useful for many kinds of knowledge work: system analysis and evaluation, documentation and education, to name a few. However, ... -
Optical fibers with periodic structures
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:48, Doctoral thesis, 2006)This thesis concerns some experimental and theoretical issues in fiber optics. In particular, properties and devices based on photonic crystal fibers (PCFs) are investigated. The work can be grouped into three parts. In ... -
Optimal Bit and Power Constrained Filter Banks
(Dr. ingeniøravhandling, 0809-103X; 2000:7, Doctoral thesis, 2000)In this dissertation, two filter banks optimization problems are studied. The first problem is the optimization of filter banks used in a subband coder under a bit constraint. In the second problem, a multiple input multiple ... -
Oscillatory Non-normal-Mode Onset of Convection in a Porous Rectangle
(Journal article; Peer reviewed, 2019)A special case of the fourth-order Darcy–Bénard problem in a two-dimensional (2D) rectangular porous box is investigated. The present eigenfunctions are of non-normal-mode type in the horizontal and vertical directions. ... -
Parametric Programming in Control Theory
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:94, Doctoral thesis, 2008)The main contributions in this thesis are advances in parametric programming. The thesis is divided into three parts; theoretical advances, application areas and constrained control allocation. The first part deals with ... -
Peaking Capacity in Restructured Power Systems
(Dr. ingeniøravhandling, 0809-103X; 2000:100, Doctoral thesis, 2000)The theme of this thesis is the supply of capacity during peak demand in restructured power systems. There are a number of reasons why there is uncertainty about whether an enegyonly electricity market (where generators ... -
Perforated Panel Absorbers with Viscous Energy Dissipation Enhanced by Orifice Design
(Dr. ingeniøravhandling, 0809-103X; 2000:67, Doctoral thesis, 2000)Currently, there is a great interest in panel absorber design where porous components are excluded due to environmental and cleaning considerations. For such absorbers, the challenge is to increase the natural, viscous ... -
Performance engineering method for workflow systems : an integrated view of human and computerised work processes
(Dr. ingeniøravhandling, 0809-103X; 1996:62, Doctoral thesis, 1996)A method for designing workflow systems which satisfy performance requirements is proposed in this thesis. Integration of human and computerised performance is particularly useful for workflow systems where human and ... -
Population balance modeling and passivity-based control of particulate processes, applied to the Silgrain® process
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:35, Doctoral thesis, 2004)This thesis deals with the systematic development of mechanistic models of particulate processes for the purposes of nonlinear controller design and implementation.The methods investigated in this thesis were illustrated ... -
Practical Thermal and Electrical Parameter Extraction Methods for Modelling HBT´s and their Applications in Power Amplifiers
(Dr. ingeniøravhandling, 0809-103X; 2003:20, Doctoral thesis, 2003)A new practical technique for estimating the junction temperature and the thermal resistance of an HBT was developed. The technique estimates an interval for the junction temperature. The main assumption in the new technique ... -
