Signal analysis, modeling and simulation of vehicle crash dynamics
(Master thesis, 2013)Vehicle crash safety has been a strong point of interest for long time in many countries due to the reason that safety statistics show high fatality rate of vehicle occupants involved in road accidents. All vehicles which ... -
Tilt rotor tricopter : control system for the holonomic multirotor platform
(Master thesis, 2013)Development of a new approach to the multicopter segment of the Unmanned Areal Vehicle (UAV) family is presented. The system is designed on a T-shaped tricopter platform with ability to tilt all three motors, hereby ... -
Deformation measurement of circular steel plates using projected fringes
(Journal article; Peer reviewed, 2013)Fringe projection is a versatile method for mapping the surface topography. In this paper, it is used to measure the deformation of steel plates under static penetration. Here, the surface shape changes continuously. ... -
Input-output finite-time stability of discrete-time impulsive switched linear systems with state delays
(Journal article; Peer reviewed, 2013)This paper is concerned with the problem of input-output finite-time stability (IO-FTS) for discrete impulsive switched systems with state delays. Sufficient conditions are presented for the existence of IO-FTS for such ... -
Bond graph modeling and simulation of wind turbine systems
(Journal article; Peer reviewed, 2013)This paper addresses the problem of bond graph methodology as a graphical approach for the modeling of wind turbine generating systems. The purpose of this paper is to show some of the benefits the bond graph approach has, ... -
Techno-economic optimum sizing of hybrid renewable energy system : rural electrification in Sri Lanka
(Master thesis, 2013)Using an off grid hybrid renewable energy-based power systems for rural electrification has become an attractive solution for areas where grid electricity is either not feasible or the cost of the grid extension is relatively ... -
Voltage regulation of a distribution grid with distributed generation

Optimization of capacitor banks in the Skagerak networks transmission grid
(Master thesis, 2013)Capacitor banks have been widely used in electric power networks. This master thesis presents a study of introducing new capacitor banks into a transmission network. The network comprises two areas at Telemark and Vestfold ... -
A Novel solid oxide fuel cell anode substrate : performance and lifetime studies
(Master thesis, 2013)The competition in the fuel cell market today is driving improved performance and among the fuel cells types the Solid Oxide fuel cell (SOFC) has a top rank because of its high efficiency in combined heat and power ... -
The Possible contribution of photovoltaic systems to the electricity supply in some districts in Palestine
(Master thesis, 2013)This thesis discusses the potential of solar energy to support and partly cover the energy demand in the medium voltage level electric supply grid in four cities in the West Bank, Palestine. The load profile for two days ... -
Energieffektive boliger : tekniske og økonomiske aspekter
(Master thesis, 2013)Økende interesse for energiproduksjon og energieffektivitet har ført til at oppgavens problemområde anses som svært spennende. De fornybare energiressursene som Norge sitter på, kan utnyttes langt bedre enn de gjør i ... -
Optical modelling for photovoltaic panels
(Master thesis, 2013)A novel approach to predict the performance of anti-reflective glasses on PV panel is presented in this thesis. Anti-reflective glass, such as deeply textured and thin film coated glass, has shown to increase the annual ... -
Electrification of the Utsira formation : electric system requirements for a power distribution platform
(Master thesis, 2013)The Norwegian oil and energy department instructs operators to look at the possibility for electrification of future offshore installations with power from shore. The offshore installations at the Utsira formation may ... -
Manure energy exploitation : the use of biogas to secure water supply in developing countries
(Master thesis, 2013)This thesis has investigated the feasibility to produce electricity for water pumping in developing countries by using a simple biogas reactor system with an internal combustion. This was done by visiting Katulani Secondary ... -
Optimization of biodiesel injection parameters based on support vector machine
(Journal article; Peer reviewed, 2013)For the running diesel engine, spray-atomization, mixed-combustion, and thermal-power conversion processes are inseparable, which causes difficulty to investigate atomization effect separately. This study was conducted to ... -
Delay-dependent H-infinity control for networked control systems with large delays
(Journal article; Peer reviewed, 2013)We consider the problems of robust stability and H-infinity control for a class of networked control systems with long-time delays. Firstly, a nonlinear discrete time model with mode-dependent time delays is proposed by ... -
Stability and l(1)-gain analysis for positive 2D Systems with state delays in the Roesser Model
(Journal article; Peer reviewed, 2013)This paper considers the problem of delay-dependent stability and l(1)-gain analysis for positive 2D systems with state delays described by the Roesser model. Firstly, the copositive-type Lyapunov function method is used ... -
Filtering for discrete fuzzy stochastic time-delay systems with sensor saturation
(Journal article; Peer reviewed, 2013)This paper addresses the H-infinity filtering problem for discrete fuzzy stochastic systems with time-varying delay and sensor saturation. Random noise depending on state and external disturbance is also taken into account. ... -
Missing value estimation for microarray data by Bayesian principal component analysis and iterative local least squares
(Journal article; Peer reviewed, 2013)Missing values are prevalent in microarray data, they course negative influence on downstream microarray analyses, and thus they should be estimated from known values. We propose a BPCA-iLLS method, which is an integration ...
