Financial report readability is an important factor influencing the decision usefulness of accounting report, which has become a common concern problem of both accounting theory and practice. For study on financial report readability, it is gradually mature in foreign countries, but in China, due to the limited measurement method of readability and other factors, the study on financial report readability...
The evaluation of the city public emergency capability is an important basis of the development of the city emergency capability. This paper made a evaluation to the eight sample cities based on the Fuzzy Set Theory. And the sample cities are choice by the three criteria such as disaster distribution, city type and geography location and so on. And they are Nanning, Harbin, Yinchuan, Shenyang, Jinan,...
This paper proposes a cross layer routing protocol which operates with Cognitive Radio (CR) Ad Hoc Networks. The new routing protocol exploits the passage of CR performance information from the Physical/MAC layers up to Network layer as contributing factors within the route selection algorithms. The performance of the proposed protocol is investigated via simulations and the results confirm its favorable...
CAPTCHA (also known as verification code) is mainly used to guarantee the login security of the interactive websites. At present, the most popular verification code is image CAPTCHA which can distinguish the human user from the computer by identifying characters in the image. Although the image CAPTCHA is safe at beginning, great deals of CAPTCHAs have been cracked by the computers along with the...
Interactive genetic algorithms (IGAs), combining the human's intelligent evaluations with the evolutionary optimization mechanisms, have been sufficiently investigated due to their powerful performance in solving problems with aesthetic criteria. User fatigue arising from intelligent evaluations, however, greatly restricts IGAs to successfully optimize complicated problems. Lot of efforts have been...
The effects of grain size distribution and intergranular phase on effective anisotropy Keff and coercivity Hc have been investigated in nanometer hard magnetic materials. In order to obtain higher Keff and Hc, grain size should be larger than 15 nm, and the grain size distribution should be as central as possible. The existence of intergranular phase may result in the enhancement of coercivity. The...
