Dong, J. (author), Zhang, Kouchi (author)In lighting systems consisting light-emitting diodes (LEDs), excessive temperature is a main cause of degraded luminous efficacy, which leads to reduced average illuminance and distorted illumination rendering. Modeling the thermal dynamics of LEDs is hence essential in designing thermal dissipators and controllers for maintaining constant...journal article 2017

(author), van de Giesen, N.C. (author)This study demonstrated a new method for mapping high-resolution (spatial: 1 m, and temporal: 1 h) soil moisture by assimilating distributed temperature sensing (DTS) observed soil temperatures at intermediate scales. In order to provide robust soil moisture and property estimates, we first proposed an adaptive particle batch smoother...journal article 2016

Dong, M. (author)As we enter era of “intelligence”, an increasing number of smart devices are being equipped around us. Such devices reflect the emerging need in microelectronics industry: increased functionality and miniaturization. As Moore’s law gradually meets its bottleneck, the concept of “More-than-Moore” (MtM) is proposed to address this issue by...doctoral thesis 2016

Dong, J. (author), Steele-Dunne, S.C. (author), Ochsner, Tyson E. (author), van de Giesen, N.C. (author)This study addresses two critical barriers to the use of Passive Distributed Temperature Sensing (DTS) for large-scale, high-resolution monitoring of soil moisture. In recent research, a particle batch smoother (PBS) was developed to assimilate sequences of temperature data at two depths into Hydrus-1D to estimate soil moisture as well as...journal article 2016

(author), Hintzen, H.T.J.M. (author)Many strategies have been adopted to improve thermal degradation of phosphors. Because of the stability and high transmittance of graphene, here we report a novel method of carbon coating on BaMgAl<sub>10</sub>O<sub>17</sub>:Eu<sup>2+</sup> (BAM) phosphor particles through chemical vapor deposition. The chemical composition, microstructure,...journal article 2016

Gao, Y. (author), Dong, J. (author), Isabella, O. (author), Zeman, M. (author), Zhang, G (author)Diverse solar irradiance spectra can be observed under different conditions of time, date, location, weather, etc. Since the solar irradiance spectrum is required by certain scientific and engineering applications, obtaining accurate spectral data is essential. Measurements by spectrophotometers are able to achieve accurate real-time data with...conference paper 2016

Lu, Y. (author), Dong, J. (author), Steele-Dunne, S.C. (author), van de Giesen, N.C. (author)Surface heat fluxes interact with the overlying atmosphere and play a crucial role in meteorology, hydrology, and climate change studies, but in situ observations are costly and difficult. It has been demonstrated that surface heat fluxes can be estimated from assimilation of land surface temperature (LST). One approach is to estimate a neutral...journal article 2016

(author)Steel is prone to corrosion induced by chloride ions, which is a serious threat to reinforced concrete structures, especially in marine environments. In this work, we report a novel capsule-based selfrecovery system that utilizes chloride ions as a trigger. These capsules, which are functionalized via a smart response to chloride ions, are...journal article 2015

Yang, X. (author), Daamen, W. (author), Hoogendoorn, S.P. (author), Chen, Y. (author), Dong, H. (author)Pedestrian dynamics has been being a popular research area. In this paper, breakdown probability in the bidirectional flow that includes pedestrians with heterogeneities is investigated. Reaction time appears to have the most pronounced breakdown proba- bility, followed by desired velocity and then body size. The relationship between the start...journal article 2014

Dong, C. (author)Uncertainty is an unavoidable part of decision making. Decisions always have to be made before perfect knowledge on their consequences is known. However, there is no ‘perfect knowledge’ in hindsight. To research uncertainty and take actions proactively becomes the challenge to scientists and decision makers. In water resources planning and...doctoral thesis 2014
