This paper presents the intelligent vehicle's highspeed steering control model based on CCD sensor, to ensure that the vehicle pass the curve stably and rapidly, and do not runaway. First, the vehicle obtain road information by CCD visual sensor, and detect the type of road and the location of the vehicle etc. Second, calculate the turning radius of the road in front of the vehicle. Third, figure out the vehicle's highest speed and servo's steering angle through turning mathematical model, establish the relationship between turning radius and speed, turning radius and steering angle. Then, in order to make the vehicle achieve the target speed quickly and stably, some mathematical analysis of the driving motor has been done, and the relationship between speed and motor's armature voltage is established. Finally, verify and calibrate the turning mathematical model experimentally. The result shows that the model algorithm is stable and accurate, and the intelligent vehicle can pass different types of road with high and stable speed.

Code search in an industrial environment is driven by the programmers wish to scan huge source code repositories with high precision in a very short time. Given a challenging scenario of a huge software repository, the question for an efficient code search backend is relevant. This paper discusses the question of an appropriate data storage model for a structured code search engine applied in an industrial development scenario, where a search on large software repositories is common. To investigate this, a search engine approach with integrated Abstract Syntax Trees is adapted. Using the capabilities of a hybrid in-memory database, we stored a big amount of structured data obtained from the source code repository into column-, row-, and a hybrid store layout and performed a set of typical queries using an SQL interface on them. The results have shown the superiority of the column-oriented approach for the investigated scenario.

A novel and practical method which is Quantum-behaved Particle Swam Optimization (QPSO) algorithm is applied in one type of turbo fan engine performance optimization. In this paper, by comparison with PSO algorithm, QPSO algorithm have obvious advantages. The simulation is carried out under different altitudes and velocities. The result shows that thrust can be increased by 7% ∼ 9% under maximum thrust mode and improved by 0.3% ∼ 3.7% than that is optimized by Particle Swam Optimization (PSO) algorithm. Meanwhile, fuel consumption can be decreased by 2% ∼ 3% under the minimum fuel consumption mode. The influence of initial values on PSO algorithm is reduced and the problem of being easily trapped in local optimal values is solved as well. Apparently, the algorithm is of great application value.

Common-frame launch has been a development trend of shipborne weapon systems, but it can increase the hazard of collision and disturbance between weapons both during launch and in flight. In order to ensure the safety of ship and weapons, common-frame launched weapons must be coordinated in airspace and time. In this paper, we put forward a kind of airspace coordination algorithm for shipborne weapons common-frame launch by analyzing the safety problems brought by common-frame launch. Then we discuss the influence of random weapon selection on the coordination results by a simulation example, and advance an improvement on the algorithm flow. The results show that the algorithm with the improved flow can avoid the bad probability of random weapon selection and resolve problems of airspace coordination.

This research deals with a three-stage integrated inventory problem of tree-type single-producer multi-distributor multi-retailer supply chain network. This paper relaxes one constraint of Wee and Yang (2004) in which shortage is not allowed. The total cost model was developed based on the model presented by Wee and Yang considering the cost of backorder. Four variables that compose the total cost function are optimized to determine the optimal replenishment policy for producer, distributors, and retailers to achieve the lowest total cost. Sensitivity analysis was also applied to evaluate the outcome of the proposed solution procedure presented in this research.

This paper is concerned with the optimum proportional-integral-derivative (PID) controller design for a PM dc motor position control. Since the evolutionary programming (EP) algorithm has been considered as a useful technique for finding global optimization solutions for certain complicated functions in recent years. In this paper, we attempt to combine the EP algorithm with the PID control design to solve the positioning control problem of a PM dc motor, such that a performance index of integrated-absolute error (IAE) is minimized. Last, a SYL-5 PM dc motor position control system is used to verify the superiority of the proposed method. It can be easily seen from the simulation results that the proposed method will have better performance than those presented in other studies.
