Gersen, C.M. (author)Object-Relational Mapping (ORM) frameworks can be used to fetch entities from a relational database. The entities that are referenced through properties are normally not fetched initially, instead they are fetched automatically by the ORM framework, when they are used by the application. This is called lazy-fetching and can result in many...master thesis 2013

Jansen, P.R. (author)CB&I is experiencing an issue in a new project to be executed in Russia, named NKNK. Despite the rich experience CB&I has with projects, there is a continuous struggle with the sourcing process in projects which it involves financing by multiple export credit agencies. The issue at stake is, CB&I does not know beforehand in which countries it is...master thesis 2013

Zegov, L.T. (author)Compressive sensing (CS) provides a new paradigm in data acquisition and signal processing in radar, based on the assumptions of sparsity of an unknown radar scene, and the incoherence of the transmitted signal. The resolution in the conventional pulse-compression radar is foreseen to be improved by the implementation of CS. An unknown sparse...master thesis 2013

Kwasieckyj, B. (author)A hybrid propulsion system features both a diesel engine and an electric motor for propulsion. The degrees of freedom with power generation raise the question how this division between power can be optimised in such a way that the engines are running with their optimal fuel efficiency. A generalised method to determine the power generation for...master thesis 2013

Shankar, A. (author)A clustered architecture is a viable design choice when aiming to increase the performance of a VLIW processor while avoiding the hardware complexity and increased access times associated with a centralized register file. However, this places additional responsibility on the compiler: the production of an efficient cluster assignment. In this...master thesis 2013

Musegaas, P. (author)The optimization of high-thrust interplanetary trajectories continues to draw attention. Especially when both Multiple Gravity Assists (MGA) as well as Deep Space Maneuvers (DSMs) are included, the optimization is typically very difficult. The search space may be characterized by a large number of minima and is furthermore very sensitive to...master thesis 2013

Backx, J.J.A.M. (author)In this research a decision model designed for the optimal planning of maintenance for road constructions to a particular section of a highway for a longer period. Optimal refers to the minimization of construction maintaining the required quality of the product and performance conditions. The optimization problem consists of assigning...master thesis 2012

Amirtha, T.R. (author)Existing re-calibration methods for instrumented treadmills have mainly been performed when the instrumented treadmill has been in static operation i.e. the belts are not running. The effect re-calibrating during experimental operation, i.e. while the belts are running, on the ground reaction force (GRF) and the center of pressure (CoP) accuracy...master thesis 2012

Mariens, J. (author)Multidisciplinary design optimizations have shown great benefits for aerospace applications in the past. Especially in the last decades with the advent of high speed computing. Still computational time limits the desire for models with high level of fidelity cannot be always fulfilled. As a conse- quence, fidelity is often sacrificed in order to...master thesis 2012

Koerselman, J.R. (author)A design methodology for composite space enclosures was generated. As a result a panel of an electronics housing structure, as part of a general satellite traversing both GEO and LEO, was designed and optimized. A mass saving of 18% was achieved over a conventional aluminum panel, while assuring structural integrity for acceleration loads,...master thesis 2012

Holt, S. (author)The upstream oil and gas industry focuses increasingly on unconventional gas resources to maintain the level of its hydrocarbon reserves. To unlock the full potential of gas shale reservoirs, horizontal wells are drilled and active stimulation of the reservoirs, in the form of multi-stage hydraulic fracturing, is performed. This new technique...master thesis 2011

Van Eldert, J. (author)In the optimization of open pit mine design, the Lerchs-Grossmann algorithm is the industry standard, although network flow algorithms are also well suited, efficient, and known. The stochastic version of the conventional (deterministic) network flow algorithm is based on the use of multiple simulated realizations of the ore deposit, thus...master thesis 2011

Crisostomo Ramirez, J.D. (author)The electricity sector in Spain had been evolving steadily in an ascendant rate since the liberalization in late 90’s. Demand was expected to keep growing but it suddenly dropped in 2009 creating an unbalance in the system in terms of demand and capacity available. In addition the increasing share of renewable energy contribution has also...master thesis 2011

Hendrich, T.J.M. (author)Traditionally, the aircraft design process is divided into three phases: conceptual, preliminary and detailed design. In each subsequent phase, the fidelity of the analysis tools increases and more and more details of the design geometry are frozen. In each phase a number of design variants is generated, fully analyzing them with the tools...master thesis 2011
