1. Moisture Transport and Moisture-Induced Distortions in Timber - an Experimental and Numerical Study
Abstract : Timber products subjected to climatic variations commonly display moisture-induced distortions that can lead to serious problems for end-users. The aim of the thesis, which consists of an extended summary and six appended papers, was to investigate the potential of using the gluing technique suggested here for dealing with problems of moisture-induced distortions and developing the heat and mass transfer models which such distortion analyses require.

2. A Finite Element Study of the Shape Stability of Sawn Timber Subjected to Moisture Variations
Abstract : Shape instability in timber products exposed to moisture variation is a serious problem since it can make wood products unsuitable for construction purposes. In this thesis the finite element method has been used to simulate deformations during the drying process.….…. READ MORE

3. Numerical Analysis of Moisture-Related Distortion in Sawn Timber
Abstract : A 3D theory for the numerical simulation of deformations and stresses in wood during moisture variation is described. The constitutive model employed assumes the total strain rate to be the sum of the elastic strain rate, the moisture-induced strain rate, the mechano-sorption strain rate and the creep strain rate.

4. Investigations on moisture damage-related behaviour of bituminous materials
Abstract : This doctoral thesis presents results of literature review on classical and contemporary aspects of stripping, as well as experimental investigations on moisture damage as influenced by bituminous materials. Previous research in the area of moisture damage was reviewed and synthesized into a state-of-the-art. READ MORE

5. By Means of Beams : Laser Patterning and Stability in CIGS Thin Film Photovoltaics
Abstract : Solar irradiation is a vast and plentiful source of energy. The use of photovoltaic (PV) devices to convert solar energy directly to electrical energy is an elegant way of sustainable power generation which can be distributed or in large PV plants based on the need. READ MORE
