  • Publication number: 20230166996
    Abstract: The present invention belongs to the field of treatment of urban organic wastes, and specifically relates to a high-value treatment system or method for urban wet garbage. According to the present invention, through the steps such as oil extraction, high-efficiency hydrolysis, high-value biological conversion, simultaneous recovery of released nitrogen and phosphorus and deep utilization of residues, urban wet garbage is converted into acetic acid by high-value treatment, produced by-products including carbon dioxide and hydrogen are biologically converted into acetic acid, released nitrogen and phosphorus are recycled into slow-release fertilizers, and solid residues are used to prepare materials capable of promoting conversion of the wet garbage into acetic acid through high-value treatment. According to the present invention, not only can high-value treatment of the urban wet garbage be realized, but also produced waste gases and waste residues are recycled.

  • Patent number: 11475979
    Abstract: Embodiments of methods, systems, and tangible non-transitory computer readable medium having instructions are presented. A method includes calculating a plurality of feature values for a number of bioinformatic features of the desired hybridization reaction; and calculating distances between the plurality of feature values and corresponding database rate constant values stored in a database, the database comprising a plurality of hybridization reactions having known rate constants. The method additionally includes calculating a weighted average of a logarithm of the database rate constant values, with larger weights assigned to value instances having values lower in distance to the plurality of feature values of the desired hybridization reaction; and providing the weighted average as a predicted logarithm of the rate constant of the desired hybridization reaction.

  • Patent number: 9551568
    Abstract: A method for operating a scanning microscope system. The optimal number of required through-focus scans, that is required to predict the position of a focal plane of the objective with respect to the object to produce the image with minimized blur, is not pre-determined but rather defined iteratively in real-time, contemporaneously with conducting the sample scanning operation itself.

  • Publication number: 20130279750
    Abstract: System and method for identification of foreign object debris, FOD, in a sample, based on comparison of edge features identified in images of the sample takes at a reference point in time and at a later time (when FOD may be already present). The rate of success of identification of the FOD is increased by compensation for relative movement between the imaging camera and the sample, which may include not only processing the sample's image by eroding of imaging data but also preceding spatial widening of edge features that may be indicative of FOD.
