Abstract: The disclosure belongs to the technical field of heat insulation materials, and discloses an in-situ microfibrillated reinforced polymer composite heat insulation foam material as well as a preparation method and application thereof. This disclosure adopts a polypropylene matrix, a fiber-forming polymer, an elastomer and an antioxidant as a foam material. The foaming material is subjected to a primary melt blending process and a hot stretching process first, then subjected to a secondary melt blending process and cooling granulation and subjected to a pressing process, and a composite board is obtained. The composite board is subjected to supercritical fluid foaming process, and a composite heat insulation foam material is obtained.

Abstract: The present invention relates to a method for tracking and locating a contamination source in a water distribution system based on consumer complaints, comprising following steps: S1: generating a contamination matrix by location information complained by consumers; S2: determining similarity between candidate nodes and classifying the candidate nodes; S3: adding a random complaint hysteresis time and constructing a consumer complaint sample; and S4: training, validating and testing a convolutional neural network by the consumer complaint sample, and using the convolutional neural network in practically tracking and locating a contamination source. Compared with the prior art, the present invention has the following advantages. The contamination source is located in the consumer complaint pattern, according to the real-time consumer complaints after a contamination accident occurs.

Abstract: A Chip on Film (COF) flexible circuit board and a display device using the COF flexible circuit board are provided. The circuit board includes: a substrate; a plurality of conductive terminals arranged separately in parallel over the substrate, each of the plurality of conductive terminals including a wide line and a narrow line; and a anisotropic conductive adhesive region provided over the substrate. A connection site of the wide line and the narrow line is located in an overlapping area of the anisotropic conductive adhesive region and the substrate. The embodiments of the invention can reduce the probability of the circuit board being broken and the undesirable phenomena such as open circuit.

Abstract: This invention contemplates an accurate and efficient estimation of gene copy number using oligonucleotide microarrays. The method integrates gene copy number data obtained from perfect match and mismatch probe sequence structure intensities and probe binding affinities. In one embodiment, an accurate determination of single nucleotide polymorphisms (SNPs) sequences is obtained. In another embodiment, an accurate detection and determination of DNA copy number alteration is obtained. In another embodiment, an accurate estimation for RNA gene expression is obtained.
