The invention discloses a deforming statistical map based multi-view spatio-temporal data visualization method and application. Spatio-temporal data having geography and time attributes is visualized by adopting a method of multi-view and multi-tag mixed layout formed by combining a traditional map, a statistical map, time axis and a pie chart, a bar graph, a bubble chart and a Nightingale rose diagram in a statistical chart, and the dissymmetry problem of data distribution and space utilization of a traditional map visualization method and the problem that the attributes of multi-dimensional data display are not comprehensively displayed are avoided. A user can be helped to understand all the aspects of data from multiple perspectives, meanwhile a classic visualized statistic analysis chart, the map time axis and the like are combined, so that data display is specific and vivid. The deforming statistical map based multi-view spatio-temporal data visualization method can be applied to the fields of data visualization of microblogs, WeChat, demographic statistics, infectious disease distribution, elector distribution and the like, and visualization and visual analysis conducted on the data having the time relation of spatial distribution are achieved.

A handbag can be easily redesigned with attachable/detachable handbag covers of virtually any design. The configurable handbag can similarly be configured to interchange various different handbag handles, also of any design. Accordingly, a handbag can be easily customized in both look and feel without necessarily requiring the purchase of multiple different handbags of different styles. In particular, a user can purchase a single (or few) base handbag(s), and alternatively purchase multiple different handbag covers and/or handbag handles to customize the handbag. The handbag covers are relatively small, and can be easily stored. In at least one implementation, the handbag covers are a tri-folding component that is attachable via magnetic fasteners.

The invention relates to a rotational inertia on-line identification method for an alternating current (AC) permanent magnet synchronous motor servo system and belongs to the technical field of rotational inertia identification for motors. The method aims to solve the problems that an on-line inertia identification method based on the traditional least square method is high in requirements for storage space and arithmetic speed of digital processing chips. The method adopts a load torque identification part to identify a constant load disturbance torque value TL; a system dynamic state judging part is adopted for judging whether rotation speed of a motor is at a dynamic change stage, and when the rotation speed of the motor is at the dynamic change stage and the rate of change of the rotation speed of the motor is higher than a critical change rate for identification of rotational inertia of the motor, a rotational inertia estimation value is obtained through calculation by utilization of a least square estimation method based on recursion; and when the rotational inertia on-line identification process meets requirements of a preset output rotational inertia estimation value and meets a requirement for precision, the rotational inertia estimation value is output and the rotational inertia on-line identification process is completed. The method is used for rotational inertia on-line identification for the motor servo system.
