de Vries, F.P.Ph. (author)Uitgaande van de voorstelling van een F.M.modulator als een tot instabiliteit teruggekoppeld elektronisch systeem, waarbij door de terugkoppeling de polen van het teruggekoppelde systeem op de imaginaire as komen, wordt aangetoond dat indien de polen van het open systeem op de negatief reèle as gelegen zijn, deze ligging zo is te variëren door...master thesis 1968

de Vries, J.P. (author)De realisering van een klok-synchroon T.D.M.A. systeem via een satelliet wordt bemoeilijkt door de bewegingen die de satelliet uitvoert ten opzichte van de grondstations. (klokfrequentie verschuiving ten gevolge van het Doppler-effect.) Een methode om toch een klok-synchroon systeem te verkrijgen, bestaat uit het bijregelen van de, door het...master thesis 1971

de Vries, J.C.Z. (author)Om in een digitale verbinding geklokte repeaters uit te sparen worden op kleine afstanden zeer eenvoudige repeaters geplaatst. Het voornaamste probleem hierbij is de intersymboolinterferentie. De intersymboolinterferentie wordt door middel van terugkoppeling gecompenseerd.master thesis 1972

de Vries, A.M.A. (author)Sound and vibrations are important aspects when designing a ship. Most of all on board passenger ships and pleasure crafts a "silent" vessel is essential. To realise this, it has to be known where the waves, because that is what sound and vibration are about, come from, how strong they are and how propagation through the vessel takes place. With...master thesis 2002

de Vries, M.J. (author)NedTrain, a subsidiary of the Dutch Railways (NS), is responsible for maintenance of rolling stock of NS. Maintenance is performed at maintenance depots and involves wheel sets that are located under trains. Wheels are subject to wear due to usage and need to be exchanged at maintenance when they have worn below a certain limit. Therefore, it is...master thesis 2013

de Vries, Veerle (author)This paper reports on the exploration of the architectural design process involving both the expression of the intuitive and tacit as well as the rational and explicit. The purpose is finding out the role and influence of design approaches and design methods within the design process regarding these opposites by reflecting on my own process in...master thesis 2016

de Vries, R. (author)The general trend in the aerospace industry is to optimise lightweight and highly flexible wing structures made of composite materials. This flexibility gives rise to static and dynamic aeroelastic instability problems. Research by Kim and Lee, Murua et al., and Drazumeric et al. have proven that chord-wise flexibility has a significant effect...master thesis 2016

de Vries, Jennie (author)One of the leading perspectives from literature is that decisions about investments should be made based on a comprehensive cost-benefit analysis and on a cyber-risk assessment. However, many organizations do not undertake this sophisticated analyses due to the lack of available data about costs, benefits and the impact and likelihood of attacks...master thesis 2017

de Vries, Daniël (author)Multidisciplinary Design Analysis and Optimization (MDAO) promises major advances in aircraft design. However, judging from todays aircraft, MDAO is clearly not fully embraced by the industry yet. This is due to technical difficulties (coupling incompatible tools) and non-technical barriers (intellectual property).<br/><br/>Recent research, such...master thesis 2017

de Vries, Romana (author)With the relocation of the industry in Rotterdam from the city centre to the sea, the old harbour area became empty. One of the buildings in this area is Santos, an old coffee warehouse that is located in Katendrecht. Due to the developments in this area, there is a need for a redevelopment for Santos as well. The shape of the waterfront is...master thesis 2018

de Vries, Rinze (author)Flood risk is increasing due to climate change and the growth of the potential consequences of flooding. Analysing how flood-proof the spatial plan is, therefore becomes more important. Since most spatial planners have limited knowledge concerning flood risk, the Netherlands’ Directorate-General for Public Works and Water Management commissioned...master thesis 2018

de Vries, Tjeerd (author)This thesis develops a continuous time framework to value deferred taxes using<br/>Black and Scholes (1973) type option pricing techniques. The valuation renders a<br/>market consistent pricing procedure, which avoids the necessity of subjective accounting principles. Our framework is flexible enough to value deferred taxes like carry forward,...master thesis 2018

de Vries, Eline (author)In 1942 cast glass columns weredesigned in the Danteum by GiuseppeTerragni. But due to the annealing timeof large glass pieces, these have neverbeen produced. Now, more than 75years later, a new type of cast glasscolumn will be designed. This time, thedesign is made out of interlocking drystacked cast glass components.Glass is a strong yet...master thesis 2018

de Vries, Anne Mathilde (author)Currently, the only effective treatment for end-stage liver diseases is liver transplantation. However, the waiting list with patients who are in need of a new liver is long, because too few good-quality donor livers are available. New techniques in the field of tissue engineering are being investigated to create a reconstructed liver, which...master thesis 2018

de Vries, Tim (author)A quick-scan algorithm has been developed in order to evaluate rooftop PV potential in the Netherlands. Both its panel fitting and yield prediction functions have been validated with existing systems monitored by Solar Monkey. The calculation times of different parts of the algorithm were measured and decreased while keeping the accuracy of the...master thesis 2018
