Jesus de Moraes, R. (author), Hajibeygi, H. (author), Jansen, J.D. (author)In data assimilation problems, various types of data are naturally linked to different spatial resolutions (e.g. seismic and electromagnetic data), and these scales are usually not coincident to the subsurface simulation model scale. Alternatives like down/upscaling of the data and/or the simulation model can be used, but with potential loss of...conference paper 2018

Jesus de Moraes, R. (author), Rodrigues, José R.P. (author), Hajibeygi, H. (author), Jansen, J.D. (author)A generic framework for the computation of derivative information required for gradient-based optimization using sequentially coupled subsurface simulation models is presented. The proposed approach allows for the computation of any derivative information with no modification of the mathematical framework. It only requires the forward model...journal article 2018

Fonseca, R. M. (author), Della Rossa, E. (author), Emerick, A. A. (author), Hanea, R. G. (author), Jansen, J.D. (author)Since the early 2000's there has been a significant focus from many groups around the world towards the development and application of innovative technologies in order to improve reservoir management strategies and optimize field development plans. Benchmark studies are a very valuable way of evaluating and demonstrating the status and...conference paper 2018

Diaz Cortes, G.B. (author), Jansen, J.D. (author), Vuik, Cornelis (author)We explore and develop POD-based deflation methods to accelerate the solution of large-scale linear systems resulting from two-phase flow simulation. The techniques here presented collect information from the system in a POD basis, which is later used in a deflation scheme. The snapshots required to obtain the POD basis are captured in two ways:...conference paper 2018

Jansen, K.M.B. (author), Tarren, Bailey (author), Slingerland, M. (author)We developed disposable and stretchable on-skin sensors for simple and unobtrusive monitoring of posture and movements during daily activities. Simple sensor platforms like these are expected to become commonly accepted in the near future, not only for posture monitoring but also for e.g. motion monitoring in sports. The paper describes the...conference paper 2018

Steijlen, A.S.M. (author), Jansen, K.M.B. (author), Albayrak, A. (author), Verschure, D. O. (author), Van Wijk, D.F. (author)Background: Cardiovascular diseases (CVD) are the leading cause of morbidity and mortality worldwide. Early diagnosis is of pivotal importance for patients with cardiac arrhythmias and ischemia to minimize the consequences like strokes and myocardial infarctions. The chance of capturing signals of arrhythmias or ischemia is substantially high...journal article 2018

(author), Krijgsheld, Pauline (author)Filamentous fungi colonize substrates by forming a mycelium. This network of hyphae can be used as a bio-based material. Here, we assessed the impact of environmental growth conditions and deletion of the hydrophobin gene sc3 on material properties of the mycelium of the mushroom forming fungus Schizophyllum commune. Thermogravimetric...journal article 2018

(author)Background: Pelvic endometriosis is often mentioned as one of the variables influencing surgical outcomes of laparoscopic hysterectomy (LH). However, its additional surgical risks have not been well established. The aim of this study was to analyze to what extent concomitant endometriosis influences surgical outcomes of LH and to determine if...journal article 2018

Diaz Cortes, G.B. (author), Vuik, Cornelis (author), Jansen, J.D. (author)We study fast and robust iterative solvers for large systems of linear equations resulting from simulation of flow trough strongly heterogeneous porous media. We propose the use of preconditioning and deflation techniques, based on information obtained frfrom the system, to reduce the time spent in the solution of the linear system.An important...journal article 2018

Jansen, J.D. (author)This ‘white paper’ proposes to develop a data-informed operational system to forecast induced seismicity, and the associated seismic hazard in the Groningen natural gas field. The goals of developing and maintaining such an Operational Earthquake Forecasting System (OEFS) are 1) to provide a unified environment to test and align research efforts...report 2018

Jansen, S.J.T. (author)In the Netherlands, the extraction of natural gas from the ground has led to soil subsidence and the occurrence of earthquakes. These earthquakes cause physical damage to buildings and give rise to psychological distress. Research on the impact of natural hazards, such as earthquakes, has shown that there is a complicated relationship between...journal article 2019

Jansen, E. (author), Pereira Machado, J.D. (author), Blanter, Y.M. (author)We consider an electromechanical system in which a microwave cavity is coupled to a mechanical resonator, with a mechanical frequency twice the microwave frequency. In this regime, the effective photon-phonon interaction is equivalent to that of a degenerate parametric amplifier, instead of the typical radiation pressure interaction. If the...journal article 2019
