Model Predictive Voltage Regulation in Active Medium Voltage Distribution Grids

Zöllner, András (author)

The renewable generation capacity, particularly solar and wind power installations, has increased steadily in the Netherlands over the course of recent years. Due to the local, small-scale nature of these power plants (compared to conventional power plants), a large share of this generation capacity is installed into the medium- and low-voltage...

Withdrawal strength of self-tapping screws in tropical hardwood

Nijkamp, Robert (author)

Self-tapping screws are popular tools used in timber engineering. The axial withdrawal strength of self-tapping screws could be used in timber structures as an active or passive application. An example of an active application is the use as a fastener in wall to wall connections. An example of a passive application is the use as reinforcement...

Fuzzy model-based disturbance rejection control for atomic force microscopy with input constraint

Mahmoudabadi, Parvin (author), Tavakoli-Kakhki, Mahsan (author), Hassan HosseinNia, S. (author)

Accurate representation of the atomic force microscopy (AFM) system is not only necessary to achieve control objectives, but it is also beneficial for detecting the nanomechanical properties of the samples. To this end, this paper addresses the issue of controller design for the AFM system based on an accurate nonaffine nonlinear distributed...

Sensitivities and prerequisites of the application of the Energy Flux Analysis to high-rise structures excited by wind using in situ measurements: Case: New Orleans tower, Rotterdam

Sonneveld, Michelle (author)

As buildings get taller and lighter, structural engineers are increasingly faced with the consequences of the dynamic response of high-rise buildings to wind. Damping is an important property for the dynamic response of high-rise structures, but is a combination of many mechanisms, which makes it a complex phenomenon to account for in the...

Drinking water temperature around the globe: Understanding, policies, challenges and opportunities

Agudelo-Vera, Claudia (author), Avvedimento, Stefania (author), Boxall, Joby (author), Creaco, Enrico (author), de Kater, Henk (author), Nardo, Armando Di (author), Djukic, Aleksandar (author), Kapelan, Z. (author), Blokker, E.J.M. (author)

Water temperature is often monitored at water sources and treatment works; however, there is limited monitoring of the water temperature in the drinking water distribution system (DWDS), despite a known impact on physical, chemical and microbial reactions which impact water quality. A key parameter influencing drinking water temperature is...

Spatial patterns in ⁸⁷Sr/⁸⁶Sr ratios in modern human dental enamel and tap water from the Netherlands: Implications for forensic provenancing

Kootker, Lisette M. (author), Plomp, E. (author), Ammer, Saskia T.M. (author), Hoogland, Vera (author), Davies, Gareth R. (author)

The analysis of strontium isotope ratios in human dental enamel has become important in the fields of archaeological and forensic science for determining provenance and hence mobility. The prerequisite for the approach relies on a correlation between dietary Sr intake and the underlying local geology. This premise is brought into question for...

Distinct cortical activity patterns in Parkinson's disease and essential tremor during a bimanual tapping task

Luft, Frauke (author), Sharifi, Sarvi (author), Mugge, W. (author), Schouten, A.C. (author), Bour, Lo J. (author), Van Rootselaar, Anne Fleur (author), Veltink, Peter H. (author), Heida, Tijtske (author)

Background: Parkinson's disease (PD) and essential tremor (ET) are neurodegenerative diseases characterized by movement deficits. Especially in PD, maintaining cyclic movement can be significantly disturbed due to pathological changes in the basal ganglia and the cerebellum. Providing external cues improves timing of these movements in PD and...

Background: The basal ganglia and cerebellum are brain structures involved in movement initiation, execution and termination. They are thought to be involved in the tremor generation and movement deficits in Parkinson's disease (PD) and essential tremor (ET). Especially in PD, maintaining cyclic movement, such as walking or tapping can be...

Robustness of attractors in tapping mode atomic force microscopy

Chandrashekar, A. (author), Belardinelli, P. (author), Staufer, U. (author), Alijani, F. (author)

In this work, we perform a comprehensive analysis of the robustness of attractors in tapping mode atomic force microscopy. The numerical model is based on cantilever dynamics driven in the Lennard–Jones potential. Pseudo-arc-length continuation and basins of attraction are utilized to obtain the frequency response and dynamical integrity of...

A comprehensive model for transient behavior of tapping mode atomic force microscope

Keyvani Janbahan, A. (author), Tamer, M.S. (author), van Wingerden, J.W. (author), Goosen, J.F.L. (author), van Keulen, A. (author)

Many investigations have focused on steady-state nonlinear dynamics of cantilevers in tapping mode atomic force microscopy (TM-AFM). However, a transient dynamic model—which is essential for a model-based control design—is still missing. In this paper, we derive a mathematical model which covers both the transient and steady-state behavior....

NO_x reduction in the Di-Air system over noble metal promoted ceria

Wang, Y. (author), Kapteijn, F. (author), Makkee, M. (author)

In this study, the role of the noble metals Pt and Rh (0.5 wt.%) for the selective reduction of NO into N₂ is evaluated by the transient TAP technique and in-situ spectroscopy using a commercial stable ceria support (denoted as CZ) and applying isotopically labelled ¹⁵NO and ¹⁸O₂. The transient...

Assessing the origin of bacteria in tap water and distribution system in an unchlorinated drinking water system by SourceTracker using microbial community fingerprints

The general consensus is that the abundance of tap water bacteria is greatly influenced by water purification and distribution. Those bacteria that are released from biofilm in the distribution system are especially considered as the major potential risk for drinking water bio-safety. For the first time, this full-scale study has captured and...

Krabbenborg, Stijn (author)

Currently, Quooker is Europe’s market leader in boiling water taps. Although initially Quooker taps were focused on providing boiling tap water in standard households, nowadays an increasing share of Quooker B.V.’s turnover is represented by taps being sold in professional markets from which the office and food & beverages (F&B) markets...

Fundamental understanding of the Di-Air system (an alternative NO_x abatement technology). I: The difference in reductant pre-treatment of ceria

Wang, Y. (author), Makkee, M. (author)

Toyota's Di-Air DeNO_x system is a promising DeNO_x system to meet NO_x emission requirement during the real driving, yet, a fundamental understanding largely lacks, e.g. the benefit of fast frequency fuel injection. Ceria is the main ingredient in Di-Air catalyst composition. Hence, we investigated the reduction...

Wang, Y. (author)

Nitrogenoxides (NOx, including NO and NOx) are a group of hazardous, toxic and harmfulgasses, which have an adverse effect on both environment and human health,e.g., acid rain, photochemical smog, and affecting the human respiratorysystem. The NOx concentration in most of the EUcities exceeds the EU annual limit value (40 μg/m3). Around40% of...
