Abad, Belkis Filian (author), Lantsoght, E.O.L. (author), Yang, Y. (author)The Critical Shear Displacement Theory (CSDT) was developed to determine the shear capacity of reinforced concrete beams based on the different shear-carrying mechanisms (concrete in the compression zone, aggregate interlock, and dowel action). This research aims at extending the CSDT to Steel Fibre Reinforced Concrete (SFRC) by adding the...conference paper 2019

Arcondoulis, Elias J. G. (author), Ragni, D. (author), Rubio Carpio, A. (author), Avallone, F. (author), Liu, Yu (author), Yang, Yannian (author), Li, Zhiyong (author)Porous coated cylinders have been shown to reduce the vortex shedding tone and broadband noise of a bare cylinder placed in uniform flow within specific Reynolds number regimes. The processes by which the vortex shedding and thus tone suppression take place are still uncertain despite numerous numerical and experimental studies. It is understood...conference paper 2019

Yang, Yujing (author), Brik, N.J. (author), de Jong, Peter (author), Gonçalves, M. (author)Framing is a crucial skill for connecting problem and solution spaces in the creative design process, both for individuals and teams. Frames are implicit in individuals’ cognitive thinking, but the creation of shared frames plays a vital role in collaborative design. Many studies have attempted to describe the framing process, but little is...conference paper 2019

Li, M. (author), Albayrak, A. (author), Zhang, Yu (author), van Eijk, D.J. (author), Yang, Zengyao (author)The usability now serves as a fundamental quality of a computational device, e.g. smartphone. Moreover, the smartphone has firmly embedded into our daily life as an indispensable part, so the context and style that user may interact with them are largely different from a decade ago. Nowadays, testing usability with end user has become a...conference paper 2019

Yang, B. (author), Slob, E.C. (author)We present a data driven method of full waveform inversion in one dimension. This means that the inversion is carried out as a sequence of processing steps. The first step is known as Marchenko redatuming. In this step we retrieve focusing functions from the measured data. In the second step we isolate the last event in the focusing function to...conference paper 2018

Yang, Xueying (author), Karampatzakis, Evgenios (author), Dörr, C. (author), Kuipers, F.A. (author)LoRaWAN is a MAC-layer protocol for long-range low-power communication. Since its release in 2015, it has experienced a rapid adoption in the field of Internet-of-Things (IoT). However, given that LoRaWAN is fairly novel, its level of security has not been thoroughly analyzed, which is the main objective of this paper. We highlight the security...conference paper 2018

(author)At the hot metal desulphurisation (HMD) stations of Tata Steel’s BOS plant in Port Talbot (UK), KAlF4 is injected together with magnesium in order to increase the fluidity of the slag and thus to decrease the iron loss. Although KAlF4 is successfully contributing to a lower iron loss during HMD, it also has a negative effect on the...conference paper 2018

Lukovic, M. (author), Yang, Y. (author), Schlangen, E. (author), Hordijk, D.A. (author)Different analytical models exist to predict the shear strength of reinforced concrete members. Generally, each of these shear strength models consists of a formulation based on certain underlying theory and fitted model coefficients. The model fitting parameters are usually established from the comparison with test data. Hence, the predictive...conference paper 2018

Lantsoght, E.O.L. (author), Yang, Y. (author), van der Veen, C. (author), Hordijk, D.A. (author), De Boer, Ane (author)As the existing bridge stock is aging, improved assessment methods such as proof load testing become increasingly important. Proof load testing involves large loads, and as such the risk for the structure and personnel can be significant. To capture the structural response, extensive measurements are applied to proof load tests. Stop criteria,...conference paper 2018

HIsarna produces hot metal with higher sulphur, lower phosphorus and manganese, almost no silicon and titanium and a lower temperature compared to the blast furnace. Because of that, desulphurisation of the HIsarna hot metal is one of the...conference paper 2017
