This paper studies unidirectional pedestrian flow in a channel by using a lattice gas model with parallel update rule. Game theory is introduced to deal with the conflict that several pedestrians intend to move to the same site. A pedestrian is either a co operator (C) or defector (D) when he or she wants to move into the same lattice as other pedestrians. Moreover, he or she could change the strategy (C or D) in the next conflict. The fundamental diagram of pedestrian flow in the channel has been investigated in details, and differences from the model with random sequential update rule have been observed. The co operators fraction is shown to exhibit an interesting non-monotonic dependence on pedestrian density. It is interesting to find that change of co operators fraction alters exponentially before the system comes to steady state. How the parameters p and q in the payoff matrix of game influence mean flow and co operators fraction is also investigated.

In the process of wave radar off-shore measurement, many factors have important influence in data collection, such as angle, distance and so on. Water depth is one of these important factors. Also water depth participates in the later inversion algorithm to affect several parameters (wave period, signal-to-noise ratio, etc.) precision. Firstly, according to the dispersion relation, it analyses the effect on those parameters qualitatively. Then the experiment results verify these analyzed results. It proves that in the inversion algorithm, if the water depth used is greater than the actual one, the signal-to-noise ratio increases, and the wave period decreases. On the contrary, the signal-to-noise ratio decreases, and the wave period will increase.

Unconventional emergency occurs unexpectedly, therefore the response system for unconventional emergency has distinct difference from classical emergency event. In order to solve unconventional emergency response problem, chance constraint response utility model (CUUM) and chance constraint response multi-objective programming model (CUMM) are developed. This paper has examined the emergency missions of unconventional emergency response, and analyzed the unconventional emergency response decision, mainly about resources and capabilities allocation. Then uncertain vector of unconventional emergency situation is generated, functions of response-decision-variable's capability are introduced. This research hopes to support the emergency response system to short response decision time and increase the response quality and efficiency by using CUUM and CUMM.

with the rapid development of storage technology, many kinds of storage products and systems have been released, but these products and systems always have some problems such as the performance is not credible, the reliability is not high and so on. In order to better test and evaluate the performance of storage products and systems, we design and implement a distributed Storage Performance Test System called SPTS, which can test the IO performance of file system and disk array. The experience of testing disk array's IOPS and data transfer rate shows that SPTS can provide certain value when customers purchase and use storage products or storage systems.

Green financial products such as green loans have developed quickly worldwide in the last 5 years. Green credit extended so far is already more than 1 trillion Yuan in China, and huge growth is expected with further development of a low carbon economy. As green loan undertakes social responsibility, such as environmental protection and energy saving, and is one of the key factors in policy decisions, the traditional credit scoring system and risk evaluation model can not be used since here only financial and management factors are considered. In this paper, a green credit scoring system is presented which introduces new environment and energy factors. A SVM risk assessment model is created on this basis. Finally, a real-world dataset is applied to test the green credit scoring system and the SVM risk assessment model. The result shows that the new green credit scoring and SVM risk assessment models are effective.

The paper based on the Jilin flood in 2010, analyses the meteorological services provided by the meteorological departments for three heavy rainstorm processes during the flood disaster, and completes the meteorological service benefit assessment and customer satisfaction index (CSI) survey. It concludes the successful experiences and disaster prevention system when meteorological departments are confronted with natural weather disasters. Given the overall framework for the construction of meteorological disaster prevention system, four methodologies appropriate for the system development - disaster monitoring, early warning information dissemination, emergency prevention and risk management mechanism -- are outlined and described.

This paper investigates the road pricing problem with extended multi-class equilibrium behaviors in the transportation networks. Taking into account mixed behaviors, where distinct Cournot-Nash (CN) players control certain portions of users, and the other users follow the user equilibrium (UE) principle, we establish the existence of meaningful road pricing in this case to decentralize a system optimal as the multiple behavior equilibrium. Considering the effect of the road pricing, some UE players may chose to give up their travel or change their travel tools, so we assume that the demand of UE players is elastic. There propose a Stackelberg leader-follower game for this problem, where the government is the network manager acting as the leader aiming to optimize network performance charging to part of network users, and the follower are the elastic demand UE players and CN players on the network. The particle swarm optimization (PSO) algorithm is used to solve the proposed model and a numerical example is provided. The computation results show that the road pricing strategy can obviously improve network performance in terms of reducing system congestion.

With the development of network, the online information has greatly enriched. It is increasingly difficult to obtain the desired information. The search engine can solve some problems, but far from satisfying people's needs. With the development of Web 2.0, RSS technology can solve some problems, greatly reducing spam, but as more and more channels appear, the user once again gets into the "information overload" situation. Therefore, in this paper, we use machine learning techniques and effective text classification techniques to solve the problem of information overload in a certain extent.
