Samkharadze, Nodar (author), Bruno, A. (author), Scarlino, P. (author), Zheng, G. (author), Divincenzo, D.P. (author), DiCarlo, L. (author), Vandersypen, L.M.K. (author)We present superconducting microwave-frequency resonators based on NbTiN nanowires. The small cross section of the nanowires minimizes vortex generation, making the resonators resilient to magnetic fields. Measured intrinsic quality factors exceed 2×105 in a 6-T in-plane magnetic field and 3×104 in a 350-mT perpendicular magnetic field....journal article 2016

Zheng, H. (author), Negenborn, R.R. (author), Lodewijks, G. (author)Large ports are seeking innovative logistical ways to improve their competitiveness world-wide. This article proposes waterborne AGVs, inspired by conventional automated guided vehicles and autonomous surface vessels, for transport over water. A predictive path following with arrival time awareness controller is proposed for such waterborne AGVs...journal article 2016

Van Hoek, Mattijn (author), Jia, Li (author), Zhou, J. (author), Zheng, Chaolei (author), Menenti, M. (author)The time lag between anomalies in precipitation and vegetation activity plays a critical role in early drought detection as agricultural droughts are caused by precipitation shortages. The aim of this study is to explore a new approach to estimate the time lag between a forcing (precipitation) and a response (NDVI) signal in the frequency...journal article 2016

Loukis, E (author), Janssen, M.F.W.H.A. (author), Dawes, S. (author), Zheng, L (author)Both private and public sector organizations tend to participate in networks in order to gain access to knowledge, skills and resources of other organizations and to create synergies to achieve highly demanding and complex goals they cannot attain individually. The governance of these networks has been recognized as being an important variable...journal article 2016

Zheng, X. (author)Natural ventilation is a traditional but effective way in buildings to adjust the indoor environment. It has also been proved to be effective in today’s design, if applied appropriately. At the same time, there is a growing trend that higher and higher buildings are constructed in the crowded city area. Air velocity, temperature and other...master thesis 2015

Zheng, Y.F. (author), Zhang, L.L. (author), Zhang, J. (author)Due to the complexity of natural ground condition, consolidation settlement is usually difficult to predict. In this study, a Pareto multi-objective optimization based back analysis method for consolidation settlement is presented in this study. The model is a coupled flow and deformation model for unsaturated soil foundation which is...conference paper 2015

Zheng, Z.Z. (author)Ports have evolved into an essential part of a nation’s economy [Schipper et al., 2015]. In order to obtain economic growth and prevent loss of trade and competitive position, the worldwide growth in port development will not stop [PIANC 2014a]. At present the port development process typically results in environmental mitigation and/or harm....master thesis 2015

(author), Lynd, L.R. (author)Clostridium thermocellum and Thermoanaerobacterium saccharolyticum are thermophilic bacteria that have been engineered to produce ethanol from the cellulose and hemicellulose fractions of biomass, respectively. Although engineered strains of T. saccharolyticum produce ethanol with a yield of 90% of the theoretical maximum, engineered strains of...journal article 2015

Yin, H. (author), Li, D. (author), Zheng, X. (author)How to evaluate crowd safety in crowded areas is a tough, but important, problem. According to accident-causing theory, uncontrolled release of hazardous energy among overcrowded pedestrians is the basic cause of crowd disaster. Therefore, crowd energy is modeled in this paper, which takes both pedestrian kinetic energy, pedestrian potential...journal article 2014

Fragkopoulou, M. (author), Desai, P.A. (author), Zheng, X. (author)This "designers' manual" is made during the TIDO-course AR0533 Innovation & Sustainability. This manual directs a designer to develop his own ideas on deep building day lighting strategies. After an introduction that defines the need for daylighting, critical regional aspects are discussed, followed by solutions. The daylighting solutions are...student report 2014

Implementing and evaluating a simplified transistor model for timing analysis of integrated circuitsZheng, X.Y. (author)Static Timing Analysis (STA) is one approach to verify the timing of a digital circuit. The currently used Gate Level Model (GLM) has limitations on performing STA for circuits when taking process variations into consideration. The transistor level model is developed taking the statistical factors into account. This thesis presents an...master thesis 2012

Zheng, C. (author)In this thesis, we will analyze swaptions whose short term interest rates are assumed to follow some affine models with dimension of factors more than two, so called multiple-factor interest rate models. Considering there is generally no analytical swaption price, we attempt to approximate it, and our discussion will focus on one of these...master thesis 2012

(author)To keep the freeway networks in a good condition, road works such as maintenance and reconstruction are carried out regularly. The resulting work zones including the related traffic management measures, give different traffic capacities of the infrastructures, which determines the travel time for road users. A work zone capacity prediction model...journal article 2011

Zheng, F. (author)Urban travel times are intrinsically uncertain due to a lot of stochastic characteristics of traffic, especially at signalized intersections. A single travel time does not have much meaning and is not informative to drivers or traffic managers. The range of travel times is large such that certain travel times can occur for congested conditions...doctoral thesis 2011
