Bahrami, A. (author)Al-Mg-Si alloys are heat treatable alloys in which strength is obtained by precipitation hardening. Precipitates, formed from a supersaturated solid solution during ageing heat treatment, are GP-zones, B", B´ and B-Mg2Si. Precipitation kinetics and strength vary with alloy composition and process parameters. There is still a need for property...doctoral thesis 2010

Almeida, A.R. (author)Chemical processes are generally operated at elevated temperatures and pressures, and energy intensive separations are usually necessary. This thesis focuses on the production of cyclohexanone, which is an intermediate of high commercial importance as a result of its use in nylon-6 and nylon-6,6 production. Using TiO2 based photo-catalysis is a...doctoral thesis 2010

Tang, S. (author)Although being a young technology, peer-to-peer (P2P) networking has spurred dramatic evolution on the Internet over the recent twenty years. Unlike traditional server-client mode, P2P networking applications are user-centric. Users (peers) generate their own content and share it with others across the Internet. Be it a P2P file-sharing network,...doctoral thesis 2010

Milovanovi?, V. (author)Modeling of the effects occurring outside the usual region of application of semiconductor devices is becoming more important with increasing demands set upon electronic systems for simultaneous speed and output power. Analog integrated circuit designers are forced to enter regimes of transistor operation that are close to or within the device...doctoral thesis 2010

Kalbasenka, A.N. (author)Crystallization is one of the oldest separation and purification techniques. Batch crystallizers are widely used in production of fine chemicals, food ingredients, specialty chemicals, and active pharmaceutical ingredients. Control of the crystalline material properties is a challenging task due to complexity and nonlinearity of batch...doctoral thesis 2009

Heus, T. (author)Cumulus clouds have since long been one of the greatest challenges in the atmospheric sciences. For a correct representation of clouds in weather and climate models, where they are the largest unknowns, a good understanding of interaction between cloud and environment is of prime importance. In this thesis, this problem is attacked with a...doctoral thesis 2008

Abrasive Waterjet (AWJ) Machining is a recent non-traditional machining process. This technology is widely used in industry for cutting difficult-to-machine-materials, milling slots, polishing hard materials etc. AWJ machining has many advantages, e.g. it can cut net-shape parts, no heat is generated during the cutting process, it is...doctoral thesis 2008

van der Helm, A.W.C. (author)Drinking water treatment plants automation becomes more sophisticated, more on-line monitoring systems become available and integration of modeling environments with control systems becomes easier. This gives possibilities for model-based optimization. In operation of drinking water treatment plants, the processes are usually optimized...doctoral thesis 2007

Dijkstra, W.O. (author)In the thesis two different models of solidification of aluminum alloys are presented and analyzed. The first 1--D solidification model is derived from the conservation of solute, heat and mass. With numerical experiments it is shown that simulations with the Finite Difference discretization must adhere a relation similar to the Courant...doctoral thesis 2007

Groot Wassink, M.B. (author)Inkjet technology is an important key-technology from an industrial point of view. Its ability to deposit various types of materials on a substrate in certain patterns makes it a very versatile technology. Though the performance criteria imposed by today's applications are quite tight already, future performance requirements will be even more...doctoral thesis 2007

Schrik, E. (author)The research presented in this thesis was done in the context of the modeling of parasitic physical effects, like field couplings and crosstalk, that may adversely affect the functional performance of Integrated Circuits (ICs). The modeling of parasitic effects, through simulations with the resulting models, provides insight into the performance...doctoral thesis 2006

Van 't Hof, C. (author)Chemical shrinkage and simultaneous build-up of mechanical properties in curing thermosets leads to the build-up of residual stresses and strains. Depending on the constraints these may cause interface failure, dimensional inaccuracy or failure in the thermoset or its surrounding structure. The present work aims at both an improved methodology...doctoral thesis 2006

Stork, M. (author)Emulsions are widely encountered in the food and cosmetic industry. The first food we consume is an emulsion, namely breast milk. Other common emulsions are mayonnaise, dressings, skin creams and lotions. Equipment often used for the production of oil-in-water emulsions in the food industry consists of a stirred vessel in combination with a...doctoral thesis 2005

Ditzel, A. (author)Ground vibrations generated by high-speed trains are of great concern because of the possible damage they can cause to buildings or other structures near the track, and the annoyance to the public living in the vicinity of the track. Particularly in soft-soil regions, where the wave speed is comparable to the speed of the trains, a strong...doctoral thesis 2003

Chen, S.P. (author)Microstructural modeling of thermomechanical processing is well established as a valuable procedure for optimizing processing conditions in the steel industry, while the similar work for aluminum industry is still an opening problem. Recovery, recrystallization and grain growth are core elements of this processing. This thesis concentrates on...doctoral thesis 2003
