Hoogendoorn, S.P. (author), Daamen, W. (author), Duives, D.C. (author), Yuan, Y. (author)Determining travel time information from Wi-Fi (or Bluetooth) sensors is not trivial due to various (often technical) reasons. In this contribution, we focus on the problem of distinguishing travel time from the time people spend performing activities (e.g. fuelling the car, standing still to watch the scenery, buying a train ticket). More...conference paper 2016

(author)We present a novel method for caging grasps in this paper by stretching ropes on the surface of a 3D object. Both topology and shape of a model to be grasped has been<br/>considered in our approach. Our algorithm can guarantee generating local minimal rings on every topological branches of a given model with the help of a Reeb graph. Cages and...conference paper 2016

Yuan, Y. (author), Hoogendoorn, S.P. (author)In big cities, the proportion of slow-mode (such as pedestrian) flows in total trip demand is steadily growing every year. Along with this trend, many concerns arise about accessibility and safety. The monitoring and the management of pedestrians serve as a potential solution to maintain the resilience of the transport network. Monitoring and...journal article 2016

Baldi, S. (author), Yuan, S. (author), Endel, P (author), Holub, O. (author)Estimation of energy models from data is an important part of advanced fault detection and diagnosis tools for smart energy purposes. Estimated energy models can be used for a large variety of management and control tasks, spanning from model predictive building control to estimation of energy consumption and user behavior. In practical...journal article 2016

Yuan, M. (author), Singh, V. (author), Blanter, I.M. (author), Steele, G.A. (author)In cavity optomechanics, light is used to control mechanical motion. A central goal of the field is achieving single-photon strong coupling, which would enable the creation of quantum superposition states of motion. Reaching this limit requires significant improvements in optomechanical coupling and cavity coherence. Here we introduce an...journal article 2015

Yuan, M. (author), Cohen, M.A. (author), Steele, G.A. (author)We study the mechanical dissipation of the fundamental mode of millimeter-sized, high quality-factor (Q) metalized silicon nitride membranes at temperatures down to 14?mK using a three-dimensional optomechanical cavity. Below 200?mK, high-Q modes of the membranes show a diverging increase of Q with decreasing temperature, reaching Q=1.27×108Q=1...journal article 2015

Yuan, J. (author), Hicks, M.A. (author)A numerical model for the design and analysis of electro-osmosis consolidation in soft clay is used to study a well-documented full-scale field test. The large-strain model, which considers coupled electro-osmosis flow, hydraulic flow and electric density flow in a deformable elasto-plastic porous medium, is briefly introduced first. It is then...journal article 2015

(author)Typically, metal particles are difficult to manipulate with conventional optical vortex (OV) tweezers, because of their strong absorption and scattering. However, it has been shown that the vortex field of surface plasmonic polaritons, called plasmonic vortex (PV), is capable of stable trapping and dynamic rotation of metal particles, especially...journal article 2015

Yuan, J (author), Papaioannou, I (author), Straub, D. (author)Landslide events often occur after rainfall events during which the pore water pressure builds up within surficial soil layers, leading to shallow slope failure. The spatial variability of the permeability parameters of the soil causes high gradients in pore water pressure when the rainwater infiltrates into the slope. In this paper, we compute...conference paper 2015

Yuan, J. (author)Consolidation of soft clay creates a lot of problems in foundation engineering, because of the very low clay permeability and high compressibility. Primary consolidation takes a long time to complete if the material is left consolidating under atmospheric evaporation, and traditional dewatering techniques, such as surcharge preloading, vacuum...doctoral thesis 2015

Due to the relatively low accuracy of pseudorange observations, the single-epoch GNSS real-time kinematic (RTK) using phase observations can be utilized to...journal article 2015

(author)2013 was nog het jaar van minder files en minder reistijdverlies, wat weer ten dele samenhing met ‘minder economie’. Maar voor 2014 was een kleine kentering voorzien: er werd weer meer verkeer en ook meer congestie opde Nederlandse wegen verwacht. In hoeverre is die voorspelling uitgekomen? En hoe staat het eigenlijk met de verkeersveiligheid en...report 2015

A contact binary asteroid consists of two components connected to each other, resulting in a highly bifurcated shape. Here, it is represented by a combination of an ellipsoid and a...journal article 2015

In literature, there are considerable debates about the mechanism causing this phenomenon. This paper studies the mechanism by analyzing real life data of two different days. The traffic...conference paper 2014
