Dong, H. (author), Huang, H. (author), Ye, G. (author)Many types of healing agents have been investigated. These agents are processed in different ways, such as adhesive polymer in capsules or hollow fibre glasses, bacteria in porous aggregates and geo-materials directly incorporated in the cementbased materials. In this study, sodium silicate powder is encapsulated in polystyrene particles ...conference paper 2013

Huang, H. (author), Ye, G. (author)Since self-healing of cracks is able to improve the durability of concrete structures, it has attracted much attention in the recent years. As known, in concrete matrix there are large amounts of cement grains remaining unhydrated, particularly in high performance concrete. Further hydration of these unhydrated cement grains has potential to...conference paper 2013

Blijlevens, J. (author), Mugge, R. (author), Ye, P. (author), Schoormans, J.P.L. (author)Designers use product attributes (e.g., trendiness) to design aesthetically appealing products. The relationships of physical properties (e.g., shape) of product designs with product attributes and aesthetic appraisal are often considered to be generalizable over product categories and markets. However, in line with an interactionist view, we...journal article 2013

Lukovic, M. (author), Schlangen, H.E.J.G. (author), Ye, G. (author), Savija, B. (author)Surface roughness of the existing concrete substrate was considered to have the greatest impact on the bond strength in repair systems. However, the influence of this parameter has been subject for debates in recent years. The effect of concrete surface roughness is not quite clear, nor there exist a clear relation between the surface roughness...conference paper 2013

Kayastha, N. (author), Ye, J. (author), Fenicia, F. (author), Solomatine, D.P. (author)Often a single hydrological model cannot capture the details of a complex rainfall-runoff relationship, and a possibility here is building specialised models to be responsible for a particular aspect of this relationship and combining them forming a committee model. This study extends earlier work of using fuzzy committees to combine...journal article 2013

Zhang, Y. (author), Ye, G. (author)The pressure to reach sustainability favours the development of ternary composite cement. The synergistic effect on mechanical behaviour at 28 days between limestone powder (LP) and pozzolanic additives, i.e. fly ash (FA) and blast furnace slag (BFS), has been documented. In order to better understand the synergistic effect, this article...conference paper 2012

Qian, Z. (author), Schlangen, E. (author), Ye, G. (author), Van Breugel, K. (author)Cracking in cement-based materials is usually not easy to predict, because of the complexity of their microstructures. Concrete is a composite material of mortar and coarse aggregates, and mortar consists of cement paste and sands. The fracture processes in these materials are related, and this paper aims to reveal the relationship by developing...conference paper 2012

Qian, Z. (author), Ye, G. (author), Schlangen, E. (author), Van Breugel, K. (author)Concrete is a composite construction material, which is composed primarily of coarse aggregates, sands and cement paste. The fracture processes in concrete are complicated, because of the multiscale and multiphase nature of the material. In the past decades, comprehensive effort has been put to study the cracks evolution in concrete, both...conference paper 2012

Zhang, Q. (author), Ye, G. (author)Portland cement paste is a multiphase compound mainly consisting of calcium-silicate-hydrate (CSH) gel, calcium hydroxide (CH) crystal, and unhydrated cement core. When cement paste is exposed to high temperature, the dehydration of cement paste leads to not only the decline in strength, but also the increased pore pressure in the paste. In this...journal article 2012

(author)A micro-electro-mechanical-system (MEMS) based, temperature triggered, switch is developed as a cost-effective solution for smart cooling control of solid-state-lighting systems. The switch (1.0x0.4 mm2) is embedded in a silicon substrate and fabricated with a single-mask 3D micro-machining process. The device switches on at a designed...journal article 2012

Lukovic, M. (author), Ye, G. (author), Van Breugel, K. (author)This paper highlights the importance of achieving durable and long-term predictable repair of reinforced concrete structures. The performance of concrete repair in past and current engineering practice, including all types of repair and application of different materials, is often unsatisfactory. One of the reasons for this lays in the fact that...conference paper 2012

Ye, Q. (author)This thesis presents the development a generic morphological model for both structured and unstructured grid and the extension to a biogeomorphological model. For the morphological model, numerical algorithms are adjusted to adapt unstructured grid and are validated against analytical solutions and flume experiments. For the bio-geomorphological...doctoral thesis 2012

Ye, Q. (author), Taheri, M. (author), Van Geenhuizen, M.S. (author)Open innovation is well conceptualized and researched for large established firms, but not for small and young ones. What makes small high-technology firms more open in search behaviour and innovation and others more closed, has remained largely unknown. This particularly holds true for university spin-off firms. The paper fills this gap and...conference paper 2012

Ma, Y. (author), Hu, J. (author), Ye, G. (author)Alkali-activated fly ash (AAF) is a promising material that exhibits comparable material properties as cement-based materials but with much less CO2 emission. In the present work, the effect of activating solution (SiO2 and Na2O content) on the performance of AAF was studied by means of isothermal calorimetry and X-ray diffraction analysis....journal article 2012
