By analyzing the factors affecting the airborne mission system, this paper applied the method of Quantified Self to the evaluation of human effectiveness in the military airborne mission system. According to the depth of interaction between people and information, we divide the information circumstance into four aspects including individual, equipment, network and environment. Then we construct a complete individual Quantified Self information interaction system by collecting physiological data, cognitive data, behavioral data and environmental data. Finally, the functional architecture and composition of the ergonomic evaluation platform are given in combination with the airborne mission system.

In the big data era, privacy preserving is a vital security challenge for data mining. Common object of privacy preserving is personal privacy, which should be kept unrevealed while data mining on group information. However, for a few sensitive groups, such as suffering from some particular disease, engaging in some special occupation or having some peculiar hobby, even if every personal data is processed for privacy preserving, group specificity can be still exposed. Therefore, we propose the concept and method of anti-data mining on group privacy information. By adding, swapping data according to our rules, the minable characteristic and group specificity of original data is destroyed and eliminated to prevent group privacy from data mining.
In this paper, we propose a clothes classification method, an application of the gcForest. The gcForest, a novel decision tree ensemble method proposed by Zhou and Feng, performs excellently in many experiments. Moreo...

Since Graphic Processing Unit (GPU) has a strong ability of floating-point computation and memory bandwidth for data parallelism, it has been widely used in the areas of common computing such as molecular dynamics (MD), computational fluid dynamics (CFD) and so on. The emergence of compute unified device architecture (CUDA), which reduces the complexity of compiling program, brings the great opportunities to CFD. There are three different modes for parallel solution of NS equations: parallel solver based on CPU, parallel solver based on GPU and heterogeneous parallel solver based on collaborating CPU and GPU. As we can see, GPUs are relatively rich in compute capacity but poor in memory capacity and the CPUs do the opposite. We need to make full use of the GPUs and CPUs, so a CFD heterogeneous parallel solver based on collaborating CPU and GPU has been established. Three cases are presented to analyse the solver's computational accuracy and heterogeneous parallel efficiency. The numerical results agree well with experiment results, which demonstrate that the heterogeneous parallel solver has high computational precision. The speedup on a single GPU is more than 40 for laminar flow, it decreases for turbulent flow, but it still can reach more than 20. What's more, the speedup increases as the grid size becomes larger.

In view of the security hidden danger of the business data in the logistics traceability system of aquatic product, the design of the information security strategy is carried out from the two angles, which are data collection and transmission. Firstly, the aquatic traceability code is designed. Then the data encryption algorithm is studied, and the data security transmission of information security protection system is built. In the intelligent collection of traceability data, QR Code is used to express the logistics trace data, then uses the improved data encryption algorithm to encryption storage about QR Code. In the transmission of traceability data, the HTTPS protocol is used to construct the client-server transmission encryption channel to ensure the integrity of the data. Finally those information security technologies about Logistics traceability data are used in a logistics traceability system of aquatic product, and the effectiveness of RC4-RSA hybrid encryption algorithm is verified. And the integrated applications enhance the system's information security.
