Compressed sensing (CS) provides a new approach to acquire data as a sampling technique and makes it sure that a sparse signal can be reconstructed from few measurements. The construction of compressed matrixes is a central problem in compressed sensing. This paper provides a construction of deterministic CS matrixes, which are also disjunct and inclusive matrixes, from singular pseudo-symplectic...
The purpose of this paper is to introduce a new eddy-current testing system for subsurface crack detection based on giant magneto resistive (GMR) sensors. The optimized probes having small dimensions and high sensitivity to low magnetic fields enhances the spatial resolution of an ECT system. Experimental results of different frequencies and different liftoff distance are presented.
Protocol identification is a key technology in the field of military electronic countermeasure. The P-AM (Preprocessing-Array Matching) algorithm based on character string matching was proposed for satellite data. First, a satellite data preprocessing algorithm was used to increase the size of data set. Then, the AM algorithm was applied to proceed the protocol identification. Finally, the complexity...
Magnetic sensor is a key component of electronic compass used to measure the magnetic field in geomagnetic navigation. The development of high-precision three-axis vector magnetic sensor is the foundation and core of the geomagnetic navigation. To improve the accuracy of measurement, on the basis of analyzing the sensor working principle and error sources, several error models are established and...
Working in a weighted Sobolev space, a new result involving superlinear nonlinearities for a quasilinear elliptic boundary value problem in a domain in is established. The proofs rely on the Galerkin method, Brouwer’s theorem and a new weighted compact Sobolev-type embedding theorem due to V.L. Shapiro. MSC: 35J25, 35J62, 65L60.
Risk management is usually neglected in the management of IT software project. But the quality of risk management plays important role in the fulfillment of IT software project. This article mainly researches on the theories and methods of risk management identification, risk assessment, risk management tactics and risk control.
Human-based Management is an inevitable development trend in modern enterprises management; it is the requirement of complete human-being development on enterprise management. Human-based management, i.e. the commonly called "human oriented", means regarding human being as the core of management activities, highlighting the management thought of promoting the completion of organization goals...
It is obvious that informal organization widely exists in social organizations, and informal organization lies in any organization, and it comes along with formal organizations. Once an informal organization appeared, it will penetrate with formal organization, and work on the activities formal organization in every aspect, especially in human resources management. The emergence of informal organization,...
This paper introduces an auto-discharging system for jigging machine based on switched reluctance motor (SRM). In this system, SRM is used to replace the traditional asynchronous motor. The hardware system, controller and software design methods are discussed in this paper. AT89C51 is taken as the core component of the speed regulation controller for SMR and works with other peripheral circuits to...
