The invention discloses a multi-vehicle coordinating lane changing control system and a multi-vehicle coordinating lane changing control method based on vehicle-vehicle communication, and belongs to the field of control over vehicles. The system comprises a sensing unit, a communication unit, a control unit and a human-computer interaction unit. The sensing unit is used for acquiring information of an own vehicle in real time, the communication unit is used for performing real-time interaction of information among vehicles, and the communication unit is used for making a decision of the coordinating lane changing feasibility and acquiring expected control quantities of the own vehicle and coordinating vehicles and realizing control over the vehicles. The method is based on the system, through collecting information of vehicles, i.e. the own vehicle, a front vehicle on an original lane, a front vehicle on a target lane and a behind vehicle on the target lane, motion statuses of the four vehicles having mutual effects are planned in a centralized manner in the lane changing process, and the own vehicle changes the lane smoothly through active coordinating among the four vehicles. By applying the multi-vehicle coordinating lane changing control system and the multi-vehicle coordinating lane changing control method based on the vehicle-vehicle communication, safety spaces among the vehicles can be fully used, the feasible lane changing chance is effectively increased, the lane changing safety is guaranteed, the driving comfort in the lane changing process is improved, and negative influences of lane changing behaviors on the upstream vehicles on the target lane are decreased.

The invention discloses an emotion analysis method which aims at network microblogs. The emotion analysis method which aims at the problem that in the traditional emotion analysis, expression of diversification emotion of emergencies is not enough is based on a multi-dimensional vector representation model. The emotion analysis method comprises extracting emotional words in combination with a clinical psychological emotion detection table and initializing emotion analysis vectors; automatically finding the network new words in the microblogs through a method which is based on large-scale corpuses and statistics, automatically absorbing the network new words and emotional identifiers which can express emotion, continuously expanding the emotion vectors and setting a gradational structure of the emotion vectors; performing multi-dimensional emotion analysis and timing sequence analysis on the microblogs based on an existing vector model.

The invention provides a model generation method, an abnormal flow detection method and device, electronic equipment and a computer readable storage medium. The abnormal flow detection method comprises the following steps of acquiring to-be-detected flow data in a target time period, acquiring a to-be-detected proportion of at least one index, inputting the to-be-detected proportion into an abnormal detection model for detection to obtain a detection result, and finally judging whether the to-be-detected flow data in which the to-be-detected proportion is located is abnormal according to the detection result. In the embodiment of the invention, through obtaining a to-be-measured proportion of at least one index of to-be-measured flow data, the proportion components contained in the to-be-detected flow data are quantized, and whether the acquired to-be-detected proportion meets the rule of historical probability distribution and integral clustering or not is judged by the aid of the abnormal detection model, so that the to-be-detected flow data are comprehensively detected, and the accuracy and comprehensiveness of detection results are guaranteed.

The invention relates to the technical field of big data, and relates to a big data-based policy information query pushing system and method. An ES database module collects webpage contents related toscience and technology policies on a website by using a web crawler technology; The policy original database module is used for integrating the data crawled by the web crawler according to the formsof a policy title, a policy source, a policy province and city area, a URL link and release time; The policy collecting and editing module is used for classifying and marking useful policy notification files again; The policy warehousing module is used for selectively warehousing and displaying the compiled policy data; The policy display module is used for carrying out listing display on the input policies; And the policy pushing module is used for immediately pushing policy information to the user. The defect that in the prior art, an existing policy cannot be timely, comprehensively and intensively inquired and pushed is overcome, and the purpose of quickly and effectively inquiring and pushing policy information is achieved.

The invention discloses a quality management system for stem cell production, which includes (1) environment control management, (2) tissue collection management, (3) blood sample collection, (4) tissue transferring management, (5) tissue separation management, (6) cell culture and cryopreservation management, (7) archives and database management system. Each independent function detection units is innovatively provided for a various kinds of cell detection means, and combined for the detection, so that not only comprehensiveness of the detection is ensured, but also oversight and man-made error in a single detection is avoided; inter-chamber quality control means is introduced, standardization of quality detection between detection part is ensured; each segment of the stem cell storage is divided into a plurality of independent units, independent process management and quality monitoring is executed, making the system beneficial to stabilization of the stem cell quality and avoidance of interference from human factors. The invention is capable of interconnecting each unit of information, and collectively using common database information.
