The design of the multi-function wireless monitoring system based on Android is designed in this paper. The system consists of superior-machine and lower-machine. The lower-machine takes ATmega16 as the core processor, and RCV420 is the signal processor for measuring and sampling the 4–20mA current signal. The superior-machine is connected with lower-machine to receive and send data by WIFI module...
In this paper, an approximate constrained optimal guidance law is proposed for Mars entry vehicles guidance. Firstly, the original guidance of Mars entry vehicle is transformed into a fixed-time optimal tracking control problem, which depends on the solution of the Hamilton-Jacobi-Bellman (HJB) equation. Considering the case the control input is constrained, a generalized non-quadratic performance...
A compact, low cost, high speed, non-destructive testing NIR (near infrared) spectrometer optical system based on MOEMS grating device is developed. The MOEMS grating works as the prismatic element and wavelength scanning element in our optical system. The MOEMS grating enables the design of compact grating spectrometers capable of acquiring full spectra using a single detector element. This MOEMS...
There is asymmetric information between the headquarter and its subsidiaries. In order to maximize their utilities, subsidiaries incline to submit fake performance information, headquarter doesn't participate subsidiaries' business operation, so it can't identify these information. In order to control subsidiaries' behavior of manipulation, this paper sets up a “principal-agent” model, and then we...
Enterprise life cycle is generally divided into four stages: establishment, growth, maturity and decline, the primary target of the enterprise during the period of establishment should be the enlargement of enterprise scale, and with which the enterprise's human resource management will be faced up with unprecedented stress: more arrangement of recruitment and training, challenge on the formal post...
