Gong, Z. (author), Gonçalves, M. (author), Latif, Ummi (author), Georgiev, Georgi V. (author)Extensive research has focused on the influence of culture on individuals’ performance in design, with either positive or negative effects. Moreover, studies have shown that it is possible to prime individuals’ cultural values to influence their behaviours in design. However, to the best of our knowledge, no study has explored priming culture...conference paper 2023

Gong, Z. (author), Gonçalves, M. (author), Nanjappan, Vijayakumar (author), Georgiev, Georgi V. (author)In recent years, there has been a growing interest among researchers in the field of virtual reality (VR) storytelling. There is a lack of studies on using VR storytelling to prime culture-related content. The cultural aspects, particularly the tendency to avoid uncertainty, have yet to be thoroughly examined within VR. Therefore, we...conference paper 2023

(author)In a fractional-N PLL, it is beneficial to minimize the input range of its phase detector (PD) as it promotes better linearity and higher PD gain for suppressing noise contributions of the following loop components. This can be done by canceling the predicted instantaneous time offset between the frequency reference (FREF) and the variable...conference paper 2022

He, Xianqi (author), Yang, Lin (author), Lu, Chao (author), Gong, Jianwei (author), Li, Z. (author)In urban environments, the complex and uncertain intersection scenarios are challenging for autonomous driving. To ensure safety, it is crucial to develop an adaptive decision making system that can handle the interaction with other vehicles. Manually designed model-based methods are reliable in common scenarios. But in uncertain environments,...conference paper 2022

(author), Liu, Qi (author), Gong, Jianwei (author), Lu, Chao (author)Precisely modeling interactions and accurately predicting trajectories of surrounding vehicles are essential to the decision-making and path-planning of intelligent vehicles. This paper proposes a novel framework based on ensemble learning to improve the performance of trajectory predictions in interactive scenarios. The framework is termed...conference paper 2022

Gong, J. (author), Patra, Bishnu (author), Enthoven, L.A. (author), van Staveren, J. (author), Sebastiano, F. (author), Babaie, M. (author)LC VCOs with low phase noise (PN) and an octave frequency-tuning range (FTR) are required for multistandard communication devices, software-defined radios, and wireline data links. A viable popular approach is to exploit multicore mode-switching VCOs for two reasons: (1) their PN improves linearly by in-phase coupling of N identical VCOs; (2)...conference paper 2022

Enthoven, L.A. (author), van Staveren, J. (author), Gong, J. (author), Babaie, M. (author), Sebastiano, F. (author)This paper presents a 15b cryo-CMOS DAC for multiplexed spin-qubit biasing implemented in a 22-nm FinFET process. The integrating-DAC architecture and the robust digitally-assisted high-voltage output stage enable a low power dissipation (157W) and small area (0.08mm2) independent of the number of biased qubits, and a 3V output range well...conference paper 2022

Takahashi, Yuya (author), Gong, Fuyuan (author), Maekawa, Koichi (author)Using numerical simulations, this study investigated the concrete expansion damage caused by the coupled action of freeze-thaw cycles (FTC) and alkali silica reactions (ASR). In the authors’ previous experiments, it was shown that a preceding ASR definitely accelerated the succeeding expansion by FTC. Further, even if the specimens have...conference paper 2021

Gong, J. (author), Sebastiano, F. (author), Charbon-Iwasaki-Charbon, E. (author), Babaie, M. (author)This paper presents a charge-sampling PLL (CSPLL), that demonstrates the best reported jitter-power FOM of-258.9 dB thanks to its high phase-detection gain and to the removal of the power-hungry buffer driving the phase detector. It also achieves-65 dBc of reference spur by both minimizing the modulated capacitance seen by the VCO tank and...conference paper 2020

Gong, J. (author), Chen, Yue (author), Sebastiano, F. (author), Charbon-Iwasaki-Charbon, E. (author), Babaie, M. (author)Low-power, low phase noise (PN) cryogenic frequency generation is required for the control electronics of quantum computers. To avoid limiting the performance of quantum bits, the frequency noise of a PLL should be < 1.9 kHz rms [1]. However, it is challenging for RF oscillators, as the heart of frequency synthesizers to satisfy such a...conference paper 2020

Gong, Yiwei (author), Janssen, M.F.W.H.A. (author)Organizations have adopted Enterprise Architecture (EA) for managing their IT-landscape and ensuring coherence among projects and activities. There is much work about approaches, methods, and tools for EA based on the assumption that their use will create business value. However, the failure of many EA efforts results in the need to...conference paper 2020

(author), Farajzadeh, R. (author), Rossen, W.R. (author)Surfactant-alternating-gas (SAG) is often the injection method for foam enhanced oil recovery (EOR) in order to improve injectivity. However, liquid injectivity can be very poor once foam is created in the near-wellbore region. In a previous study, we reported core-flood experiments on liquid injectivity after foam flooding and liquid...conference paper 2019

(author)Automated Static Analysis Tools (ASATs) are an integral part of today’s software quality assurance practices. At present, a plethora of ASATs exist, each with different strengths. However, there is little guidance for developers on which of these ASATs to choose and combine for a project. As a result, many projects still only employ one ASAT...conference paper 2017

(author), Vdovin, Gleb (author)We present a reference-less and time-multiplexing phase retrieval method by making use of the digital micromirror device (DMD). In this method, the DMD functions not only as a flexible binary mask which modulates the optical field, but also as a sampling mask for measuring corresponding phases, which makes the whole setup simple and robust.
