In this paper, we study on evaluating physical education teaching quality based on the entropy model. The entropy model is a measure of the uncertainty associated with a random variable, which is a powerful tool in many research fields. Next, a physical education teaching quality evaluation method is designed by obtaining the maximum information entropy based on the index systems, which include 12...
As far as a Turbo decoder is concerned, the lower Bit Err Rate (BER) at the expense of acceptable and feasible complexity, the better. In this paper, a method is proposed which employs additional redundant sequence added at the end of tail bits of an information sequence to improve performance of a Turbo decoder. Computer simulation results show that, when L=L'=1024, where L is the length of information...
The problem of computing such minimal active sensor which can cover the target region completely is NP-hard. This paper designs a novel method, in which the detection area is divided into lots of virtual grid. So area coverage can approximately be considered as point coverage. Then the problem of area coverage turns into set covering problem. An improved ant colony algorithm is proposed for the minimal...
