Abstract: Disclosed is a non-transitory computer readable medium storing a computer program, in which when the computer program is executed by one or more processors of a computing device, the computer program performs operations to provide methods for detecting flaws, and the operations may include: extracting a flaw patch from a flaw image including a flaw; preprocessing at least one of the flaw image or non-flaw image not including a flaw; extracting a non-flaw patch from at least one of the preprocessed flaw image or non-flaw image; and training a neural network model for classifying patches to flaw or non-flaw with a training data set including the flaw patch and the non-flaw patch.

Abstract: A domain name system includes a native language domain name registrar, which receives a native language domain name registration request. The native language domain name comprises at least one non-alphanumeric character not included in the allowable character set for domain name registration, i.e., the English alphabets A through Z, the Arabic numbers 0 through 9 and the hyphen “-”. Each of the non-alphanumeric characters is converted to a string of alphanumeric characters to produce an alphanumeric domain name comprised of strings of alphanumeric characters uniquely representing the native language domain name being requested to be registered. The resulting alphanumeric domain name is registered with the domain name registration system, and is used in the domain name/IP address entry in the domain name server (DNS).

Abstract: An oxygen sensor probe for a boiler including a U-shaped zirconia element that is to be brought in contact with an exhaust gas in the interior of a cylindrical probe body attached to a plug and arranged together with a thermocouple in the longitudinal direction of the body. A heater for heating the element is provided around the periphery of the element and a protective filter is provided on the top portion of the body. The probe is characterized by the U-shaped zirconia element 11 being located at an upper end of the probe body 12 with its concave open portion 11' facing upwards to be contacted with the exhaust gas while its convex closed portion 11" faces downward to be confronted with the thermocouple 16.

Abstract: Apparatus and a method for evaluating the plane strain stretch formability for thin steel sheets used in automotive bodies to provide easy evaluation of the plane strain stretch formability. The apparatus includes: a lower die and an upper die with a lock bead installed thereon. A rectangularly shaped test specimen is inserted between the upper and lower dies and, and is clamped by means of the lock bead along the circumferential edge of the test specimen, so that the material of the test specimen can be moved into the upper die. A punch is elevated to apply a stretch forming force on the test specimen, and then, the plane strain stretch formability is evaluated based on the fracture limit punch height at the instant of the fracture. The punch has a saddle-like, semi-cylindrical shape.

Abstract: Polyester compositions containing an effective amount for flame retardancy of a copolymer of (1) benzene phosphorus oxydichloride, (2) 2,4'-thiodiphenol, 4,4'-thiodiphenol, 2,4'-sulfonyl diphenol, 4,4'-sulfonyl diphenol or mixtures thereof, and (3) POCl.sub.3 are disclosed.
