Quality Assessment

Scanning technology (3D laser scanner technique) measures the dimension of a precast concrete panel using extraction algorithms to measure boundary points with a compensation model to increase measurement accuracy (Kim et al., 2013). 3D laser scanning converts CAD models into BIM, which identifies scanned objects by ensuring precision for rebar mapping before actual drilling as well as rebar detailing for installing rebar cages (Hajian & Brandow, 2012). Before shipping precast concrete elements, dimensional quality assurance (DQA) is carried out to ensure that there are no dimensional defects using a scanner in an automated process that saves time and labor input ( ...

Raman spectroscopy is dependent on scattering of light. When light interacts with matter, energy exchange can take place through absorption, simulated emission, Raman scattering or spontaneous emission. In Raman scattering, the emitted photons have less energy and lower frequency in comparison with the absorbed photons. Some energy of the emitted photons is transferred to the molecules. Raman spectroscopy is a method which collects the chemical fingerprints associated with molecules. Every molecule has different levels of vibrational energy and the emitted photons experience shift in their wavelengths. The wavelength shifts are collected,examined and analyzed for sample identification. Raman spectroscopy ...

Surgical fires happen rarely, but should be taken into consideration, for they can have serious consequences for the hospital’s patients, employees, and the institution as well. It’s necessary to learn the ways to prevent such fires and the ways to deal with inflaming if it happens. (“Surgical Fire Prevention”, 2012). The research on the matter shows that up to 650 surgical fires occur in the US operation rooms each year, with up to 5% causing death or serious harm (Rocos & Donaldson, 2012). According to Feldman, L., Fuchshuber, P. & Jones, D. B. (2012) nearly 44% of fires during ...

The invention of the scanning tunnelling microscope, in 1982 resulted in the emergence of a whole new category of microscopic techniques. All these techniques fall under the family of probe microscopy, which basically involves the interaction of a sample with the sharp tip of a probe at distances of the order of a few μm to a few nm. The atomic force microscope (AFM) is one such scanning probe microscope that builds an image that describes the surface topology of a sample based on the atomic forces of interaction between the tip of the probe and the sample surface. ...

Rapid Prototyping Processes and Operations

20.3 Virtual prototyping and how it differs from additive methods Virtual prototyping refers to a technique in the product development process that involves the use of computer-aided engineering (CAE), computer-automated design (CAutoD) and computer-aided design (CAD) software. The software helps in validating a design before one goes ahead to make a visible prototype (kishorebondada, 525). We can achieve this by creating three-dimensional models and combining them to form assemblies. The software can go ahead to simulate the operation of the machine or any object under design. Additive methods, on the other hand, are layered rapid prototyping operations that include ...

Abstract

The following summary discusses the cooling techniques of atomic vapor in several different ways. Additionally, it tends to relate the evolution of experiments that are used in studying shallow layered fluids. Starting with the atomic condensates, the method is known as trapping. However, it exists in many ways from the laser system to the Bose-Einstein methods. The methods of cooling are different due to the evolutionary progress made by science. The use of laser beams includes the study of light forces on atoms which lead to either an absorption or emission of a photon. While the contraction of matter ...
