Variability of fuel consumption and CO2 emissions of a gasoline passenger car under multiple in-laboratory and on-road testing conditions
- An increasing divergence regarding fuel consumption (and/or CO2 emissions) between real-world and type-approval values for light-duty gasoline vehicles (LDGVs) has posed severe challenges to...
Study of methane enrichment in a biogas fuelled HCCI engine
- Biogas has been a promising alternative fuel for IC engines. However, its CO2 content reduces calorific value and ignitability. The CO2 fraction of raw biogas can be separated out by various...
Quantitative analysis on cold start process of a PEMFC stack with intake manifold
- To systematically explore the low-temperature operating characteristics of polymer electrolyte membrane fuel cell (PEMFC) stack, a three-dimensional PEMFC stack model with intake manifold is...
Experimental Investigation of the TRM-to-Masonry Bond after Exposure to Elevated Temperatures: Cementitious and Alkali-Activated Matrices of Various Densities
25/12/2021 - Limited research has focused on the effect of high temperatures on the textile-reinforced mortar (TRM)-to-masonry bond. In this study, masonry prisms that were furnished with double-layered TRM...
Design optimisation of braided composite beams for lightweight rail structures using machine learning methods
15/02/2022 - Braided composites have seen substantial industrial uptake for structural applications in the past decade. The dependence of their properties on braid angle provides opportunities for...
Structural Performance of a Precast Concrete Modular Beam Using Bolted Connecting Plates
19/12/2021 - In modular structures, prefabricated modular units are joined at the construction site. Modular structures must ensure splicing performance by connecting modular units sufficiently. The bolted...
Crashworthiness capability of thin-walled fibre metal laminate tubes under axial crushing
- This study aims to evaluate the crushing behaviour of aluminium-glass fibre reinforced plastic (GFRP) with different layer configurations known as fibre metal laminate (FML) subject to dynamic...
Evaluation of New Hollow Sleeve Composites for Direct Post-core Construction
02/12/2021 - The preset shape and diameter of a prefabricated FRC post rarely follows the anatomy of the root canal. To solve this problem, a new hollow sleeve composite (HSC) system for post-core construction...
Development of an O-polysaccharide based recombinant glycoconjugate vaccine in engineered E. coli against ExPEC O1
- Extraintestinal pathogenic Escherichia coli O1 is a frequently identified serotype that causes serious infections and is often refractory to antimicrobial therapy. Glycoconjugate vaccine...
Analytical Model and Numerical Analysis of Composite Wrap System Applied to Steel Pipeline
25/10/2021 - Composite overwraps are a cost-effective repair technology, appropriate for corrosion defects, dents, and gouges for both onshore and offshore steel pipelines. The main benefit of polymer-based...
Leakage analysis of steel wire reinforced polyethylene composite pipe used for waste water transportation
01/12/2021 - Leakage failure had occurred near the electrically melted sleeve of steel wire reinforced polyethylene composite pipes (SRTP, DN200 PN1.6 MPa) which was used for waste water transportation in...
Experimental study on flexural behaviour of prefabricated concrete beams with double-grouted sleeves
- A novel precast concrete beam connected using double-grouted sleeves was developed to reduce pouring concrete on-site and expedite construction. This paper presents a systematic experimental study...
Statistical Interactions and Boson-Anyon Duality in Fractional Quantum Hall Fluids
- We present an exact scheme of bosonization for anyons (including fermions) in the two-dimensional manifold of the quantum Hall fluid. This gives every fractional quantum Hall phase of the electrons...
Spatially-resolved reaction profiles in Fischer-Tropsch synthesis – influence of operating conditions and promotion for iron-based catalysts
01/10/2021 - The complex reaction mechanism of iron-based Fischer-Tropsch synthesis comprises of manifold primary and secondary reaction pathways. Within this work, an experimental setup for spatially-resolved...
Cyclic behavior of joints assembled using prefabricated beams and columns with Engineered Cementitious Composite (ECC)
- This paper studies cyclic behaviors of joints assembled by prefabricated beams and columns made using Engineered Cementitious Composite (ECC). Five large-scale joint specimens were prepared and...
True Mechanism of Spontaneous Order from Turbulence in Two-Dimensional Superfluid Manifolds
- In a 2D turbulent fluid containing pointlike vortices, Lars Onsager predicted that adding energy to the fluid can lead to the formation of persistent clusters of like-signed vortices, i.e., Onsager...
The Effect of Flow Rate of a Short Sleeve Air Ventilation Garment on Torso Thermal Comfort in a Moderate Environment
07/08/2021 - In recent years, air ventilation garments (AVG) have been reported effective to improve thermal comfort. In this study, an AVG incorporated with small fans was investigated on torso thermal...
