Akram, M. (author), Bhowmik, S. (author), Jansen, K. (author), Ernst, L.J. (author)Titanium is one of the most effective materials for structural application of space craft and aviation. Titanium alloys are widely used in solid rocket booster cases, guidance control pressure vessel and other different applications demanding light weight and reliability. Aerospace industry is also a larger market for titanium products and...conference paper 2010

Van Essen, G.M. (author), Van den Hof, P.M.J. (author), Jansen, J.D. (author)In oil production waterflooding is a popular recovery technology, which involves the injection of water into an oil reservoir. Studies on model-based dynamic optimization of waterflooding strategies have demonstrated that there is a signifcant potential to increase life-cycle performance, measured in Net Present Value. However, in these studies...conference paper 2010

Fonseca, R.M. (author), Leeuwenburgh, O. (author), Jansen, J.D. (author)In a recent study two hierarchical multi-objective methods were suggested to include short-term targets in life-cycle production optimization. However this previous study has two limitations: 1) the adjoint formulation is used to obtain gradient information, requiring simulator source code access and an extensive implementation effort, and 2)...conference paper 2012

Barros, E.G.D. (author), Jansen, J.D. (author), Van den Hof, P.M.J. (author)This paper proposes a new methodology to perform value of information (VOI) analysis within a closed-loop reservoir management (CLRM) framework. The workflow combines tools such as robust optimization and history matching in an environment of uncertainty characterization. The approach is illustrated with two simple examples: an analytical...conference paper 2014

Neele, F.P. (author), De Leeuw, G. (author), Jansen, M. (author), Stive, M.J.F. (author)The first results are presented from a quantitative model describing the aerosol production in the surf zone. A comparison is made with aerosol produced in the surf zone as measured during EOPACE experiments in La Jolla and Monterey. The surf aerosol production was derived from aerosol concentration gradients measured downwind from the surf zone...conference paper 1998

Van Doren, J. (author), Markovinovic, R. (author), Jansen, J.D. (author)During the design of development concepts for the exploitation of oil and gas reservoirs, frequent use is made of numerical simulation of the flow of multi-phase fluids through porous rock. Recently, increased attention has been paid to systematic optimization of well positions and operating parameters (rates, pressures) over the life of the...conference paper 2006

Jansen, S.J.T. (author)The decreasing importance of socio-economic factors in choosing a place to live gives more room to other motivational factors. These can be examined using affordance-based theory (Gibson, 1979), which explores what use the environment has to the user. In a telephone survey, 738 respondents were asked for their preferred residential environment...conference paper 2015

Namdar Zanganeh, M. (author), Kraaijevanger, J.F.B.M. (author), Buurman, H.W. (author), Jansen, J.D. (author), Rossen, W.R. (author)We apply adjoint-based optimization to a Surfactant-Alternating-Gas foam process using a linear foam model introducing gradual changes in gas mobility and a nonlinear foam model giving abrupt changes in gas mobility as function of oil and water saturations and surfactant concentration. For the linear foam model, the objective function is a...conference paper 2012

Skandali, M. (author), Jansen, K.M.B. (author), Koussios, S. (author), Sinke, J. (author), Benedictus, R. (author)The purpose of this study is to simulate the two-dimensional, transient and continuous heat transfer during the thermoset Automated Tape Laying (ATL) process. The heat transfer analysis is coupled with a cure kinetics model of the thermoset prepreg tapes used for the process. Unlike most studies, the process is modelled in a Lagrangian framework...conference paper 2015

(author)The influence of fiber-matrix adhesion on the linear viscoelastic creep behavior of as received and surface modified carbon fiber (AR-CF and SM-CF, respectively) reinforced polyphenylene sulfide (PPS) composite materials was investigated. Short-term tensile creep tests were performed on ±45° specimens under four different isothermal condition;...conference paper 2014

Lelieveld, C. (author), Jansen, K.M.B. (author)A composite structure consisting of a Shape Memory Polymer (SMP) matrix and three Shape Memory Alloy (SMA) strips was constructed. The SMA strips act as actuators which create forward and backward angle bends of 90 degrees of the composite structure. The function of the polymer matrix was to give the structure enough stiffness. During the...conference paper 2013

Fatemi, S.A. (author), Jansen, J.D. (author), Rossen, W.R. (author)An enhanced-oil-recovery pilot test has multiple goals, among them to verify the properties of the EOR agent in situ. Given the complexity of EOR processes and the inherent uncertainty in the reservoir description, it is a challenge to discern the properties of the EOR agent in situ. We present a simple case study to illustrate this challenge: a...conference paper 2015
