the automation of visual inspection for printed labels, which are coated with rubber and curl, we have developed a camera-based portable experimental device of automatic inspection in this research. By experiments, we have verified that the experimental device surely detect the failures such as the stain, the patchiness, the spread, and the chip detected by using low dimensional feature vectors...
Rainfall and its associated storm water runoff have been associated with transport of many pollutants into beach water. Fecal material, from a variety of animals (humans, pets, livestock, and wildlife), can wash into beach water following rainfall and result in microbial contamination of the beach. Many locales around the world issue pre-emptive beach closures associated with rainfall. This stu...
We have studied electron tunneling through water between two metal electrodes supported on a solid substrate and observed random fluctuations in the tunneling current between two discrete levels. The two-level fluctuations persist when changing the concentration and the valency of the ions, and pH of the water solutions. A given two-level fluctuation is, in general, not affected by the applied ...
A novel and quite simple method to establish a traceability link between air velocity and the national standards of mass and time is presented in this paper. The method is based on the humidification of flowing air before the blower of a wind tunnel with a known mass flow of water. Then air velocity can be calculated as a function of humidification water flow. The method is compared against a P...
Circular drop manholes are widely implemented for steep catchments in urban drainage networks. Poor downstream hydraulic transition processes of a manhole system, i.e., the formation jump near outlet entrance, and sudden from free surface to pressurized flow with bursts air outflow pipe can severely constraint capacity water conveyance. In this paper, we defined four basic stages that indicate ...
Knowledge about the extent of genotype in environment interaction is helpful for farmers and plant breeders. This because it helps them choose proper strategies agricultural management breeding new cultivars. The main contribution this paper to investigate on environmental using GGE biplot method (Genotype Genotype-by-Environment) ten canola experimental design was a randomized complete block (...
