The Effect of Bridge Orientation in Casting Machine on the Castability and Quality of Base Metal Castings
Introduction: The aim of this study was to evaluate the effect of bridge orientation in casting machine on castability and quality of base metal castings. Methods: Three groups of patterns with different direction and lengths in casting machine were casted and then studied qualitatively and quantitatively using mean and standard deviation in table of frequency. Results: Larger nodules and poros...
متن کاملMachine Vision Based Inspection of Textile Fabrics
Several issues on automatic inspection of textile fabrics are discussed in this paper. To avoid the intense computation for real time inspection, we suggest a parallel pyramid hardware architecture consisting of several channels with CCD cameras in different resolutions working simultaneously. In inspection algorithms, we use a hierarchy of improved BP neural networks which demonstrate a tree s...
متن کاملMachine Vision Inspection of Web Textile Fabric
The paper describes instrumentation which uses machine vision to inspect rolls of web textile fabric in real time. This involves detection of "message" signals arising from defects buried in noise caused by fabric structure. Analogy with the detection of targets in radar and sonar is exploited to provide effective signal processing. The hardware implementation achieves efficiency with economy b...
متن کاملMachine-Stitched E-textile Stretch Sensors
Truly wearable sensing poses challenges in many areas. To be successful, wearable sensors must preserve wearer comfort while providing accurate sensor data. Further, for widespread commercial production they must also be compatible with soft goods manufacturing. Here, we present a method of fabricating stretch sensors using common apparel sewing machinery. The response of sensors made using ind...
متن کاملDiscrimination of Brazilian propolis according to the seasoning using chemometrics and machine learning based on UV-Vis scanning data
Propolis is a chemically complex biomass produced by honeybees (Apis mellifera) from plant resins added of salivary enzymes, beeswax, and pollen. The biological activities described for propolis were also identified for donor plant's resin, but a big challenge for the standardization of the chemical composition and biological effects of propolis remains on a better understanding of the influenc...
