that there are any irregularities along its width. Given this situation, standard contact method for surface scanning could be used. On the other hand, when the whole surface area needs to be scanned instead... a surface 3D scanner [1-3]. There are usually two ways of scanning the surfaces; in the first method thin laser line to highlight the device’s profile is used while in the other, only light background......
as additives for CPB preparation was proposed and studied by a few experts, and it has been illustrated to be an effective method to improve the tensile and compressive strengths of CPB in some successful cases..., accurate and low-cost methods for the strength evaluation of fiber-reinforced CPB. One method that is often used to predict the UCS of the CPB by researchers includes establishing an empirical formula......
from damage by shocks from road or ground surfaces[1-2]. The heat insulating plates are joined by a sheet metal method known as clinching. Clinching has been used for almost 25 years and there has been much research into this method[3-7]. The traditional clinching technique used to combine the upper and lower heat insulation plates of a catalytic converter has two steps: first, the flanges......
] was granted to Boliden Mineral AB for its proposed flowsheet in 2002. This paper gives a description of the precipitation method and presents some test data produced during the BioMinE project. 2 Two-stage precipitation method The proposed two-stage iron removal process is based on precipitation using a controlled neutralization process employing limestone, lime or a similar alkaline material......
nanostructures[4-5]. The solution-based hydrothermal methods have also been used for the synthesis of 1D ZnO. Compared with the vapor phase methods, the hydrothermal method has some distinctive advantages... on the formation of 1D ZnO in ZnSO4-Na2CO3 system. In the present work, a facile hydrothermal decomposition method was developed to synthesize ZnO whiskers in alkaline media, using ZnSO4 and Na2CO3......
widely in the computation of the governing equation for FENE dumbbell model. Generally speaking, it can lead to accurate results compared to the approximate theoretical method[4-6]. Brownian dynamic simulation is not a good method to explain the physical properties. On the other hand, simulation is sometimes time consuming. Analytical method makes the explanation of the physical phenomena more......
texture characteristics. The sheet possessing specifical texture characteristics and properties can be controlled through fit rolling process. The pack ply-rolling process is an effective method to produce Ti-6Al-4V alloy thin sheet[1-2]. This method should lower the product cost and improve the mechanical properties of the alloy sheet. This paper introduces the effects of texture characteristics......
Introduction The method for production of tantalum metal powder for tantalum capacitors in large scale was developed by HELLIER and MARTIN in 1950s, and was improved by the following research. Potassium... electron microscopy (JEOL TEM-200CX, Japan JEOL Co.). 2) Nitrogen content in the black powder treated at 900 ℃ was measured by pulse-heating inert-gas fusion thermoconducting method (Model TC-436......
particles or other phase, depending on the processing method. The aim of the present work is to investigate the effect of K and Si content on the high-temperature properties and microstructure of molybdenum... with diameter of 17 mm, the green compact was sintered in a induction furnace. The sintered AKS doped Mo rod was processed to Mo wire with diameter of 0.7 mm by drawing method. The content of doped......
or non-metal ions[2-4], depositing noble metals[5-6], surface sensitization[7] and composite semiconductor[8-9]. Doping transition metals or non-metal ions are effective method to improve... were prepared from tetrabutyl titanate through sol-gel method, characterized by means of X-ray diffraction (XRD), energy dispersion X-ray spectrum (EDS) and Brunauer-Emmett-Teller (BET) surface area......
