For a more accurate measurement, the correct emissivity value of the investigated building material is necessary to consider. Furthermore, for thermal images with many different equipment is necessary to consider different emissivity, one for each material. Consequently investigations of emissivity ...
Wang and his Ph.D. student, Weixing Hao, tested the various fabrics and materials using a scanning mobility particle sizer, which measures particle size and concentration. They then compared the "filtration efficiency" of multiple layers of each material against different aerosol particle sizes, ran...
“I consider this an investment in my future, and I feel it has made a difference in my ability to pass the exam. If you take the time to do the homework, look at the course material, and ask questions during the class, the expense is worth it. I am confident it gave me a leg...
Latvia has forests; therefore, wood as the building material can be considered as the resource available on the local market. It is one of the oldest materials, which is used in civil engineering, as its positive properties ensure the stable demand for it. Timber is the only widely available...
to buildings and civil engineering infrastructure. Construction features give a particular flavor to LCA, because of the broad diversity of construction artifacts, the huge mass of materials involved that need to be included in a circular economy approach, the variety of materials contributing to a ...
In this paper, we review the current research into deep learning for detection, modelling and planning for material deterioration. Driving such research are factors such as budget reductions, increasing safety and increasing detection reliability. Based on the available literature, researchers are making...

The results show that the parallel cementation model can better reflect the mechanical properties of rock material16,17. So the linear contact model is adopted between the wall and the particles, and the linear parallel cementation contact model is adopted between the particles. The maximum radius ...
CA mortar has been widely used in the high-speed railways of Japan, Germany, and China, it is a kind of inorganic–organic composite material compounded by cement (C), asphalt (A), sand (S) and various admixtures [1], [2], [3]. According to the difference of elastic modulus and st...
Experimental study on mechanical behavior of silty-fine sand reinforced by a new type of permeable polymer material under dry-wet cycles The functional calculation model between the specimens and the initial grouting conditions under dry-wet cycles was constructed, and the main influencing ...
