Zhao, Y. (author), Robal, T. (author), Lofi, C. (author), Hauff, C. (author)The use of mobile technology has become a part of our daily<br/>lives and enabled us to perform tasks that once were possible only on<br/>stationary computers on-the-go anywhere and at any time. This shift<br/>has also affected the way we learn. The use of mobile devices on-the-go<br/>requires users to multitask and divide attention between...conference paper 2018

Robal, T. (author), Zhao, Y. (author), Lofi, C. (author), Hauff, C. (author)Massive Open Online Courses (MOOCs) have become an attractive opportunity for people around the world to gain knowledge and skills. Despite the initial enthusiasm of the first wave of MOOCs and the subsequent research efforts, MOOCs today suffer from retention issues: many MOOC learners start but do not finish. A main culprit is the lack of...conference paper 2018

Zhao, M. (author), van Dalen, K.N. (author), de Oliveira Barbosa, J.M. (author), Metrikine, A. (author)This paper addresses the dynamic response of an infinitely long cylindrical structure embedded in an elastic half-space. The structure has a circular cross-section and its axis is parallel to the half-space surface. Excitation can be incident body waves or forces applied on the surface of the half-space and/or the structure. The model can be...conference paper 2018

Zhao, T. (author), Palardy, G. (author), Villegas, I.F. (author), Benedictus, R. (author)Ultrasonic welding is a promising assembly technique for thermoplastic composites and it is well-suited for spot welding. In this study, two typical welding process control strategies, i.e. displacement-controlled and energy-controlled welding, were selected to manufacture spot-welded joints. The influence of different boundary conditions,...conference paper 2017

(author)Ultrasonic welding is a promising assembly technique for thermoplastic composites and it is well-suited for spot welding. In this paper, the in-plane and out-of-plane mechanical behaviour of ultrasonically spot-welded and mechanically fastened joints are investigated by double-lap shear and pull-through tests, respectively. Special attention was...conference paper 2016

Taal, A. (author), Itard, L.C.M. (author), Zeiler, W. (author), Zhao, Y (author)A much occurring problem in the Energy Management Systems of existing buildings and HVAC services is that the measurements are unreliable. In this article a methodology is described which can be used to determine the presence of errors in energy monitoring, caused by faulty measurements. These errors can be detected and subsequently diagnosed....conference paper 2016

Zhao, Z. (author), Ledoux, H. (author), Stoter, J.E. (author)The LoD2 building models defined in CityGML are widely used in 3D city applications. The underlying geometry for such models is a GML solid (without interior shells), whose boundary should be a closed 2-manifold. However, this condition is often violated in practice because of the way LoD2 models are constructed and exchanged. Examples of the...conference paper 2013

Zhao, J. (author), Stoter, J. (author), Ledoux, H. (author), Zhu, Q. (author)Many 3D GIS applications require 3D building models with different LoD (Level of Detail) that satisfy certain quality criteria. However, because of their complexity, most detailed 3D building models available are still produced manually, which results in inevitable geometric and topological errors. These errors hinder the downstream processing...conference paper 2012
