Chang, Moohyun (author)In his paper, Conway presents his remarkable findings, leaving the task of careful examination and verification to us. He unveils a special link between the extraFib series and the Empire State Building, and reveals an unexpected relationship between Fibonacci numbers, Lucas numbers, and trigonometric formulas. This fresh concept, labeled ...bachelor thesis 2023

Chang, Jakka (author)The Generalized Gamma Distribution (GGD) is a three-parameter distribution with desirable properties. For certain values of the parameters, the GGD can reduce to the gamma, exponential and lognormal distribution, among others. This makes it a flexible distribution that can be used in various scenarios. The problem with implementation of the GGD...bachelor thesis 2022

Chang, L. (author), Rots, J.G. (author), Esposito, R. (author)Research has shown that lateral boundary conditions can have a large influence on the force capacity of two-way spanning unreinforced masonry (URM) walls subjected to out-of-plane (OOP) loading. Differently than laterally free one-way spanning walls, they show a higher force capacity, which however is underestimated by current analytical...book chapter 2020

Chang, Z. (author), Schlangen, E. (author), Šavija, B. (author)This paper reports an extended lattice model for printing process simulation of 3D printed cementitious materials. In this model, several influencing factors such as material and geometric nonlinearity are considered. Using this model, green strength of cementitious material is investigated, deformation and crack pattern can be derived, which...book chapter 2020

Han, Yeonjung (author), Chang, Yoon-Seong (author)The objective of this study was to present the wood properties and drying characteristics of sawtooth oak (Quercus acutissima Carruth.) for the spread of its utilization in South Korea. The annual ring, latewood ratio, dimension of vessels, density, and shrinkage of specimens manufactured from five sawtooth oak trees were measured and compared...conference paper 2019

Chang, Yoon-Seong (author), Kim, Min-Ji (author), Shin, Hyun-Kyeong (author), Han, Yeonjung (author)Based on the 2017 statistics of the Korea Forest Service, the amount of annual production of domestic roundwood was 4.5 million ㎥. Twenty eight percent of the production was hardwood roundwood. About 80% of the hardwood was Quercus species. The hardwood roundwoods were mainly used for wood chips (50%) and medium density fiberboard (MDF)(26%)....conference paper 2019

Yakovenko, S.N. (author), Chang, K.C. (author)In the present study, the surface tension is introduced as volume forces according to the continuum surface force (CSF) model [1] using the surface tension coefficient and the mollified volume fraction (color) function. The latter can be taken in the first approximation as the volume fraction defined numerically due to (possible) smoothing of...conference paper 2006

Chang, Z. (author), Zhang, H. (author), Schlangen, E. (author), Šavija, B. (author)The aim of this work is to investigate the fracture process of concrete under various boundary conditions. Although numerous concrete fracture tests have been reported, showing the failure behavior of concrete, their evaluation is ambiguous due to the limitations of specimen size and experimental conditions. Therefore, it is necessary to use...conference paper 2019

These two control objectives can be achieved without modifying the control architecture or the control parameters. The proposed method has guaranteed stability in the Lyapunov sense and also has robustness...conference paper 2022

(author)This paper presents a power- and area-efficient 9-channel LNA array for piezoelectric ultrasound transducers to enable real-time 3D imaging with miniature endoscopic and catheter-based probes. In view of the relatively low impedance of piezoelectric transducers, the LNA is implemented as a capacitive feedback voltage amplifier, rather than a...conference paper 2015
