Quantification of Effective Flow Resistivity for Parametric Assessment of Pervious Concrete by Using Ultrasonic Pulse Velocity Method

The use of nondestructive ultrasonic pulse velocity (UPV) testing to assess the hardened properties of pervious concrete (PC) mixtures is an emerging research area. Further, UPV has been successfully used to determine the effective flow resistivity (EFR) of asphalt concrete and cement concrete pavements. However, no research studies have...

Investigating Surface Fractures and Materials Behavior of Cultural Heritage Buildings Based on the Attribute Information of Point Clouds Stored in the TLS Dataset

To date, the potential development of 3D laser scanning has enabled the capture of high-quality and high-precision reality-based datasets for both research and industry. In particular, Terrestrial Laser Scanning (TLS) technology has played a key role in the documentation of cultural heritage. In the existing literature, the geometric properties...

On the Painterly Depiction of Materials: An Interdisciplinary Study on the Depiction and Perception of Materials within Paintings

The world around us is filled with materials. Our ability of visual material perception informs us how to navigate and interact with our environment. It tells us, for example, whether food is fresh, if a chair is strong enough to sit on, how much force to use to pick up a glass, etc. Painters have studied how to depict the world and the...

Long-term material and structural behavior of high-strength concrete cantilever bridge: Results of 20 years monitoring

In 1997, the Second Stichtse Bridge was built in the Netherlands using the balanced cantilever method. The use of high-strength concrete was proposed. At that time, the long-term behaviour of this material was not known, and no code provisions were applicable. Therefore, it was proposed to monitor the material behaviour and the deflections of...

A Method for Studying Climate-related Changes in the Condition of Decorated Wooden Panels

Museum objects are often highly complex and composed of materials with varying properties, some of which may have changed as a result of ageing and/or conservation treatments. Research into defining sustainable environmental conditions by balancing energy cost and risk to these vulnerable objects has mainly focused on experiments in...

Tailoring the Mechanical Properties of High-Aspect-Ratio Carbon Nanotube Arrays using Amorphous Silicon Carbide Coatings

The porous nature of carbon nanotube (CNT) arrays allows for the unique opportunity to tailor their mechanical response by the infiltration and deposition of nanoscale conformal coatings. Here, we fabricate novel photo-lithographically defined CNT pillars that are conformally coated with amorphous silicon carbide (a-SiC) to strengthen the...

Biodegradable materials: A research and design handbook; enhancing the use of biodegradable materials on building's envelopes in the Netherlands.

This master thesis dealt with 12 biodegradable materials that were researched extensively under various parameters, aiming to a better understanding of those materials and their potentials as future building materials in the Netherlands. The main research question of “which products and systems will enhance the use of biodegradable materials on...

Materials for Action: A Performative Material Toolkit for Social Interaction Design

Social networking sites are today playing an essential role in our daily lives. These web-based services not only focus on providing people a platform to share interests and activities, but also facilitate the process of keeping in touch with families and friends. Take Facebook, the most popular social networking website, as an example: people...

Folded plate assemblies with branching column supports: Interaction and control of overall shape

The work described in this paper aims at developing the interrelation and overall effects of interaction between a folded plate roof structure and a system of branching column supports. In the context of architectural performance it is of interest to discuss the effects of the material on environmental conditions. The current study is...

Investigation of the relation between growth mechanism and material properties of amorphous silicon solar cells

Thin film silicon solar cells are produced by using plasma deposition techniques. With this technique a thin film layer of silicon, most commonly amorphous silicon (a-Si: H), can be deposited on a substrate. The material properties depend largely on the plasma properties and the growth mechanism. The investigation of the correlation between...

Methods for reducing energy dissipation in cosmetic gloves

For cosmetic reasons, hand prostheses are provided with cosmetic gloves. Their pleasing appearance, however, is accompanied by poor mechanical behavior, resulting in a negative influence on prosthesis operation. Glove stiffness is high and nonlinear, and internal friction in the glove material causes energy dissipation (hysteresis). In this...

Stochastic approaches for damage evolution in standard and non-standard continua

Structural lightweight concrete: Recent research

As a result of a number of reasons new interest developed into the use of lightweight aggregate concrete. Within the scope of this development, a modernized code for lightweight concrete had to be written. In order to support this development, a number of research projects have been carried out. The aim of the research was to verify the...
