Error analysis of a stereo-vision-based tube measurement system
A stereo vision-based measurement system was developed to inspect a tube and its joints. As shown in Fig. 1(a), a tube can be described by the bending points located at the intersection of two end-to-end straight segments and the start- and end-points of the tube .
CONCRETE MIXING RATIOS - WHAT IS THE BASIC MIXING RATIO FOR
This mixing ratio will give you a concrete mix that is strong, durable, and good for most concrete projects. A cubic yard of concrete will fill an area 8 feet wide by 10 feet long by 4 inches thick, or 80 square feet @ 4 inches thick. At 6 inches thick a cubic yard of concrete will fill an area 52...
Chemical feed systems can be classified according to the components used, the type of material to be fed (powder or liquid), the control scheme employed, and the application. FEED SYSTEM COMPONENTS. Chemical Storage. Treatment chemicals are usually delivered and stored in one of three ways: bulk, semibulk, and drums.
Feedforward and Ratio Control
Feedforward and Ratio Control In Chapter 8 is was emphasized that feedback control is an important technique that is widely used in the process industries. Its main advantages are as follows. 1. Corrective action occurs as soon as the controlled variable deviates from the set point, regardless of the source and type of disturbance. 2.

Influence of Simulated Acid Rain Corrosion on the Uniaxial
Jul 15, 2012 · An experimental study on the uniaxial tensile property of concrete exposed to the acid rain environment was carried out. Acid rain with pH level of 1.0 was deposed by the mixture of sulfate and nitric acid solution in the laboratory. Dumbbell-shaped concrete specimens were immersed in the simulated acid rain completely. After being exposed to the deposed mixture for a certain period, uniaxial ...
Design and management of manufacturing systems for production
In the quality and productivity performance of mixed-model assembly systems under human errors was evaluated. In it was reported that about 20% of the defects in the Fuji Xerox China photocopy machine assembly systems was connected to operators errors. It was the second cause for defects in the analysed plant.
Four Characteristics of a Primary Standard Substance
