Essays on development economics by Wang, Wen

“…The estimation results remain robust when subjected to further checks and sensitivity tests. In addition, we consider alternative channels including pathogen stress, historical population density and colonization, which may also influence the degree of institutionalized democracy via the cultural dimension of collectivism / individualism. …”

Advances in 3D optical profilometry by Huang, Lei

“…In addition, a practical phase retrieval framework is proposed for multi-frequency phase shifting method to accurately calculate the absolute phase and automatically identify invalid phase points via a thresholding and criterion checking process. For dynamic application, only a single frame of data is available to retrieve the wrapped phase and then unwrap it. …”

Nonequilibrium hyperuniform fluids by Lei, Yusheng

“…The first one is the systems stemmed from random organization (RO) dynamics, which is a model originally proposed to describe the chaotic particle motion in sheared non-Brownian suspensions. The subsequent one is the hyperuniform systems found in active particle systems, including hyperuniform reactive particle fluids and the chiral active brownian systems and biological algae systems, etc. …”

Fabrication and characterization of graphene and carbon nanotube reinforced bioceramic nanocomposites by Hu, Huanlong

“…Bioceramics play an important role in the replacement and regeneration of human tissues, but their intrinsic brittleness and low wear resistance make the monolithic bioceramics still problematic for load-bearing applications. The two dimensional (2D) graphene and one dimensional (1D) carbon nanotube (CNT), as the secondary strong and tough biocompatible nanofillers, are popular nanocarbons to reinforce bioceramics. …”

Amino-functionalised β-diketiminate ligands (N-nacnacs): Synthesis and coordination chemistry with Main Group elements by Huan, D

“…The establishment of a library of germylenes and stannylenes bearing different N-bound aromatic substituents with varying degrees of steric bulk allows for a systematic study of the steric effects of the flanking aryl groups on the overall molecular metrics of these complexes. …”

Smart material based on magnetorheological elastomer and its 3D printing by Bastola, Anil K.

“…The 3D printability of different materials has been studied by measuring their rheological properties and it was found that the highly shear thinning, and thixotropic properties are important for 3D printability. …”

Stability improvement and control optimization of isolated two-stage AC-DC-DC converter systems by Feng, Fan

“…The analysis results offer instructive implications to fine-tune the design rules of the DAB converters. Bearing the mind that the impedance model of the DAB converter is closely related to the modulation schemes, the impacts of three typical modulation methods on the DAB impedances are analyzed and compared. …”

Physical unclonable function based solutions to unification of user, device and data authentication by Zheng, Yue

“…At a time of rampant public media manipulation and ease of fake image/video fabrication, verification of benign and malicious image transformations is necessary but not sufficient for fact checking of visual artefacts presented in the court of law. …”

Development of schlieren-image based flow diagnostics and analysis for supersonic jet flows by Lim, Desmond Haoxiang

“…When compared against PIV results, the much higher spatial and temporal resolution of SIVOF resulted in sharper and clearer vortical structures that can be tracked across several time-resolved frames. An embedded shear layer resulting from subsonic flow downstream of a 0.9 mm diameter Mach disk was also observed, which is testament to the high-fidelity flow field offered by SIVOF. …”
