Abstract: The electronic flight bag in China with few products owning Chinese independent intellectual property is attracting increasing attention in the field of the civil aviation industry in recent years. This paper introduced a level 1 EFB(Electronic Flight Bag) for general aviation with iOS as research platform. In order to realize interactive electronic checklists and automatic generation of electronic flight log, C/S model is adopted to store, update and display cabin documents, such as aeronautical charts, flight manual. Experiments show that electronic flight bag based on mobile terminal can provide the user with a good experience, which greatly reduces the pilots cabin burden and is closer to the users requirements. Moreover, the system provides an efficient way to improve safety of flight safety. Therefore, the electronic flight bag has good market prospect and practical promotional value.

Abstract: In order to study the influence by non-uniformity of illumination on testing performance of optical measurement system, the causes of non-uniformity were analyzed. We constructed the relationship model between interval distance of LED light source and illumination. The distribution of illumination with different intervals of LED were simulated. Then relationship model between viewing-field angle at object plane of optical system and illumination was established. Influence of viewing-field angle at object plane on distribution of illumination was studied. The experimental results indicate that non-uniform light source and wide viewing-field angle are two main causes for non-uniformity in optical imaging system. Larger interval distance of LED or viewing-field angle will result in non-uniformity of illumination.

Abstract: Based on the theorem of generalized synchronization for discrete chaos systems, a new discrete chaos synchronization system was designed. Using the new system and the properties of sensitive dependent on initial condition, a novel S-box generation approach was proposed. An affine transformation was used to shuffle S-box. Testing the cryptographic properties shows that the S-box generated in the proposed algorithm has sound cryptographic performance.

Abstract: In this paper, we investigate the Hyers-Ulam stability of the functional equation ƒ(2x+y)+ƒ(2x-y)=8ƒ(x)+2ƒ(y) in fuzzy Banach space using the fixed point method.

Abstract: The aim of the present paper is to establish some new nonlinear retarded integral inequalities which provide explicit bounds on unknown functions. The inequalities given here can be used as tools in the qualitative theory of certain integral equations

Abstract: The problem of birthday is an ancient and interesting problem in probability theory. The traditional birthday problem has a conclusion that the probability of the same birthday among people will reach 50% when the number of people reached 23. This paper studies the issue of people with a given distribution and discusses the probability that people have the same birthday among a given crowd.

Abstract: Many Studies has carried on the technology of detecting invariants, for example, Daikon can detect most of invariant by presetting some types of them. But unary polynomial inequality likely invariants are rarely discovered by traditional tools. An effective method to detect unary polynomial inequality likely invariant was proposed in this paper. Through analyzing the property of value ranges of unary polynomial inequality likely invariants, the algorithm set the threshold value and calculates neighbor distances to determine the form of invariants. Finally, experimental results are given to demonstrate the effectiveness of this method.

Abstract: Based on the distinguishable ball-into-box issue, this paper started from a seemingly simple ball and extended to the question of birthday frequency distribution, i.e. people birthday in different dates probability distribution and the distribution law. In addition, the value was obtained by Monte Carlo simulations with different frequency distribution birthday days, finally when frequency simulation is large, achieving the theoretical value of the frequency values to estimate the probability,and the corresponding distribution can be obtained.

Abstract: By introducing the norm and two parameters, we give a multiple Hardy-Littlewood-Polya inequality with a best possible constant factor.

Abstract: A class of backward stochastic differential equations are studied. We obtain the comparison theorem of these backward stochastic differential equations under non-Lipschitz coefficient.
