The expandable multifunctional integrated- construction skyscraper building platform includes: a building foundation part, including an underground level, a basement level and a ground level which form a main body; an external frame part, a bottom of the external frame part being fixed deep into the underground level, and a top of the external frame part running through the basement level and the ground level to reach upper air such that lifting platform parts arranged on the external frame part are capable of going up from the underground level for construction; a transportation elevator part and a three-layer enclosure part, mounted on the building foundation part; a top transfer part, mounted on a Chinese character “Ri” frame at a top of the external frame part; and a carrying tower.

Abstract: A multi-tower linkage type aerial hoisting platform includes: four tower crane body lifting/lowering parts respectively disposed in an outer periphery of a building to form a rectangle through enclosure, and including a tower crane body and a self-climbing lifting/lowering system that is capable of climbing or descending step by step along the tower crane body; four tower-crane-body-connected support beams, respectively disposed on two opposite self-climbing lifting/lowering systems, where a hoisting platform enclosed by the tower-crane-body-connected support beams is driven by the self-climbing lifting/lowering systems to move up and down synchronously; and four movable tower crane bases, respectively disposed at lower ends of the four tower crane body lifting/lowering parts, including movable chassis that are used as movable supports with a variable platform angle and support parts disposed on the movable chassis, where four corners of the support parts are respectively provided with rotary drilling fasteni

Abstract: An intelligent waste wooden formwork recovery and recycling system includes a screening part, a feeding part, and a processing part. The screening part includes a wood board unit, a wood strip unit and a wood block unit disposed inside a frame unit. The feeding part includes three conveying units inclined and disposed within an installation unit, and ends of the three conveying units are respectively aligned with the wood board unit, wood strip unit and wood block unit. The processing part includes a compaction unit, a moving unit, a discharging unit, a gauze unit, and a glue brushing unit sequentially disposed on a bracket unit. Wood materials are classified into three types and the three-layer conveying mechanism effectively controls an addition order of the wood material, significantly improving an utilization rate of the wood materials and ensuring a uniform density distribution of the compacted wood materials.

Abstract: A rotary digging drill includes three disk drills arranged in ascending order of diameter, each with a cavity therein. The disk drill includes two circular ring seats arranged side by side, multiple toothed digging buckets disposed at peripheries of the two circular ring seats, and ring gear racks respectively disposed on inner sides of the two circular ring seats. Adjacent ones of the disk drills have the toothed digging buckets facing opposite directions, and the disk drills all rotate in a direction facing a large opening, enabling adjacent two of the three disk drills to rotate in opposite directions. The rotary digging drill further includes three disk drill supports that match the three disk drills in quantity and are configured to support and drive the three disk drills.

Abstract: Disclosed is a method for encoding DNA/RNA sequences based on bidirectional trinucleotide position-specific propensities and pointwise joint mutual information, which consists of the steps: constructing the nucleotide position-specific propensity matrix of DNA/RNA sequences; constructing the bidirectional dinucleotide position-specific propensity matrix of DNA/RNA sequences; constructing the bidirectional trinucleotide position-specific propensity matrix of DNA/RNA sequences; determining the value of pointwise joint mutual information of the nucleotides of DNA/RNA sequences; concatenating features and encoding DNA/RNA sequences. In order to extract more position information of trinucleotides from DNA/RNA sequences, a parameter ? is introduced to represent the distance between the current nucleotide and its forward or backward adjacent dinucleotide, the numerical feature vectors obtained from different values of ? are concatenated into a high-dimensional numerical feature vector.
