Abstract: A cleaning base station includes a base, a first electrode, an infrared module, and a guiding member. The base includes an open chamber accommodating a cleaning robot, and the open chamber includes a chamber sidewall extending in an arc shape. The first electrode is arranged on the chamber sidewall and contacts a second electrode of the cleaning robot. The infrared module is arranged on the chamber sidewall and aligns the cleaning robot. The guiding member is arranged on the chamber sidewall and protrudes from the chamber sidewall, the guiding member is capable of extending into a guiding groove defined on the cleaning robot, the guiding member includes a guiding part, the guiding part is positioned on one end of the guiding member far away from the chamber sidewall, and a cross-sectional size of the guiding part gradually decreases along a direction away from the chamber sidewall.

Abstract: A data analysis-based energy-saving control method for a precision air conditioner in a cloud computing data center, a medium, and a system, initially trains a Bayesian linear regression model based on historical datasets of heat source data of a cloud server and control quantity data of a precision air conditioner, and is used to predict a temperature difference between temperature sensors in a data center in future time, obtain newly-added training data in real time in a control process, update the Bayesian linear regression model in real time, predict the temperature difference between the sensors in real time, and obtain an optimal control quantity of a combination of a frequency of a discrete compressor and an opening degree of a water valve in real time by using a grid search algorithm to control an actual temperature difference between the sensors in the future.

Abstract: A tungsten-base alloy material and a preparation method therefor. The preparation method comprises: 1) evenly grinding composite powder containing tungsten and zirconium oxide, and then performing annealing treatment at 700-1000° C. to obtain powder A; and 2) grinding and then compression moulding the powder A, and then performing liquid-phase sintering to obtain a tungsten-base alloy blank so as to obtain the tungsten-base alloy material.

Abstract: An apparatus for direct analysis of the redox products, or intermediates, of an electrochemical reaction by coupling an electrochemical cell to desorption electrospray ionization mass spectrometry.

Abstract: A fully automatic, parameter free MR interpretation system is based on human logic emulation. Information is derived mainly from an MR spectrum with maximum confidence and in a similar way as a human expert. This is achieved by the combination of different expert systems that interpret certain MR spectral features as well as features from a proposed structure. The expert systems are dynamically linked to each other and the analysis is performed iteratively in all directions in a way that the expert systems can utilize all of the interpretations of all expert systems at all times. The expert system may generate not just a single result but rather lists of probability weighted hypotheses.
