Mapping Atlas of Shenzhen - Urban Villages

This publication is in response to the call of 2017 Bi-City Biennale of Urbanism\Architecture (Shenzhen) (UABB) “Cities, Grow in Difference”, from the perspective of urbanism: the synthesis of factors that collectively determine the spatial use of the city. <br/>This atlas is based on master graduation theses of Delft University of Technology ...

Nonlinear nearshore wave environment for ship motion

Preferential concentration of particles in compressible turbulence

The behavior of particles in compressible turbulence has been seldom investigated to date despite its importance in many natural and industrial flows. Direct numerical simulations of particle-laden compressible isotropic turbulence are performed to study the preferential concentration of particles and the underling mechanisms. It turns out that...

Analogical Assessment of Train-Induced Vibration and Radiated Noise in a Proposed Theater

This study presents the analogical assessment of the train-induced vibration and radiated noise in a proposed theater. The theater is to be constructed in a region with crowded metro lines, and the assessment is implemented in an analogical building with comparable structural type and metro condition. Prior to the assessment, the comparability...

Analysis and Mitigation of Biases in Greenland Ice Sheet Mass Balance Trend Estimates From GRACE Mascon Products

Mascon products derived from Gravity Recovery and Climate Experiment satellite gravimetry data are widely used to study the Greenland ice sheet mass balance. However, the products released by different research groups—JPL, CSR, and GSFC—show noticeable discrepancies. To understand them, we compare those mascon products with mascon solutions...

Design and assessments on a hybrid pin fin-metal foam structure towards enhancing melting heat transfer: An experimental study

Solar energy, as a kind of renewable energy, offers a large reserve to be harvested at a reasonably low cost for engineering applications. To decouple the temporal and spatial relevance of the continuous energy supply of solar energy, latent heat thermal energy storage can deal with this problem at different temperatures. Aiming to improve...

Characteristics of ceramic fiber modified asphalt mortar

Ceramic fiber, with a major composition of Al₂O₃ and SiO₂, has advantages of stability at relatively high temperature, big specific surface area and resistance to external mechanical vibration. It has the potential contribution of improving the rutting resistance and temperature sensitivity of modified asphalt...

Simultaneous photocatalytic and microbial degradation of dye-containing wastewater by a novel g-C₃ N₄ -P₂₅ /photosynthetic bacteria composite

Azo dyes are very resistant to light-induced fading and biodegradation. Existing advanced oxidative pre-treatment methods based on the generation of non-selective radicals cannot efficiently remove these dyes from wastewater streams, and post-treatment oxidative dye removal is problematic because it may leave many byproducts with unknown...

ж青中多环芳烃荧光特征及其浓度梯度下的 响应机制硏究

Polycyclic Aromatic Hydrocarbons (PAHs) in asphalt materials is a type of serious environmental hazard, and the main pollution resource in road engineering. Aiming at the requirement of PAHs rapid detection method in asphalt pavement construction for low environmental hazard, this research concentrated in experiments about PAHs content,...

Chemo-physical characterization and molecular dynamics simulation of long-term aging behaviors of bitumen

To further explore the long-term aging behaviors of bitumen from the multiscale perspectives, the experimental characterization and molecular dynamics (MD) simulation methods were performed. Series of chemical properties for the virgin and various aged bitumen were evaluated using the TCL-FID, ATR-FTIR, Elemental analysis and GPC tests. The...

Analysis on mechanical characteristics of welded joint with a new reinforced device in high-speed railway

High-speed railways adopt continuous welded rail to maintain the smoothness and continuity of the rail surface. However, the welded joint became one of the weakest parts. In order to clear the characteristics and mechanical properties of the new reinforced device, a dynamic three-dimensional vehicle-reinforced device-track coupling model is...

Cross-Comparison and Calibration of Two Microscopic Traffic Simulation Models for Complex Freeway Corridors with Dedicated Lanes

Realistic microscopic traffic simulation is essential for prospective evaluation of the potential impacts of new traffic control strategies. Freeway corridors with interacting bottlenecks and dedicated lanes generate complex traffic flow phenomena and congestion patterns, which are difficult to reproduce with existing microscopic simulation...

How Fear of External Threats Plays Roles: An Examination of Supervisors’ Trait Anger, Abusive Supervision, Subordinate Burnout and CCB

In times of uncertainty, such as during COVID-19, many organizations experience profit decline, and employees develop a fear of external threats, such as organizational layoffs. However, most of the literature focuses on how people’s fear influences their well-being. Less is known about how employees’ fear of external threats influences their...
