Abstract: The design aims at the central kitchen to flow the system, realizes a lot of function, such as order management, merchandise delivery, storage management, financial control and so on. The system bases on the characteristic of central kitchen which is about "one contains many", follows the simple, economically and practical principle, set up the algorithm for delivery, optimizes the situation for the vehicle, considers the priority of customer, optimized the route of merchandise delivery, enhances the efficiency, reduces the cost, and the order management, the storage management the situation of dynamic management of storage management are more scientific and standardized. Moreover the system has supported the financial analysis function, and the enterprise cost can be analyzed and appraised by mathematics model.

Abstract: In this paper, we establish a nonlinear weakly singularity Wendroff type integral inequality with two variables, which generalizes the unknown function with a variable to composite function of nonlinear function with unknown function with two variables. Under certain conditions, the estimation of unknown function is given by the technique of amplification, variable substitutions, integration and differentiation, discrete Jensen inequality.

Abstract: Today's wireless communication has become the primary means of communication, the wireless communication relative to wired communications, its random parameter channel delay problem and fading problem raising a new challenge to the reliability of communication. This article describes the basic principle of OFDM system with interleaving and de-interleaving, Verification platform to build on this basis, and using EDA tools Quartus II functional and timing verify the correctness, Giving the integrated circuit simulation results, also showing the use of FPGA to achieve interleave and interleaving process well in OFDM systems. Effectively improve the reliability of the system, not only meet the needs of Systems on flexibility and real-time, but also occupy less hardware resources, fast, and consistent with the development trend of modern communications.

Abstract: Based on the empirical likelihood method, an instrumental variable based testing procedure is proposed for linear regression models with instrumental variables. The proposed testing method can attenuate the effect of endogeneity of covariates. Some simulations indicate that the proposed testing method is more powerful.

Abstract: In this paper, we establish a new weakly singularity integral inequality with two variables, which generalize the unknown function with a variable to composite function of power function with unknown function with two variables.

Abstract: To carry out an effective classification and recognition for target, this paper studied the target owned characteristics, discussed a decryption algorithm, gave a feature extraction method based on the decryption process, and extracted the feature of palmprint in region of interest. Moreover, this paper used the wavelet transform to extract the energy feature of target, gave an approach on matching and recognition to improve the correctness and efficiency of existing recognition approaches, and compared it with existing approaches of palmprint recognition by experiments. The experiment results show that the correct recognition rate of the approach in this paper is improved averagely by 2.34% than that of the existing recognition approaches.

Abstract: Cloud computing environment is regarded as a kind of multi-tenant computing mode. With virtulization as a support technology, cloud computing realizes the integration of multiple workloads in one server through the package and seperation of virtual machines. Aiming at the contradiction between the heterogeneous applications and uniform shared resource pool, using the idea of bin packing, the multidimensional resource scheduling problem is analyzed in this paper. We carry out some example analysis in one-dimensional resource scheduling, two-dimensional resource schduling and three-dimensional resource scheduling. The results shows that the resource utilization of cloud data centers will be improved greatly when the resource sheduling is conducted after reorganizing rationally the heterogeneous demands.

Abstract: In this paper, we discuss the upper and lower bounds of unknown functions in several nonlinear integral inequalities. Firstly, we give out the upper estimation of unknown function of a nonlinear integral inequality. Secondly, we give out the lower estimation of unknown function of another nonlinear integral inequality. Finally, we discuss the upper and lower bounds of a linear integral inequality by adopting novel analysis techniques, such as change of variable, amplification method, differential and integration.

Abstract: In this paper, a kind of prevent drunk driving system is designed, which is based on the ARM9 core, alcohol detection module, GPS module, GSM module, voice module, LCD (Liquid Crystal Display), power and other functional modules are included in this new system. The system detect alcohol concentration, prevent drunk driving through the voice prompt and send text messages to a preset phone number. The system has absorbed the idea that most of the hardware functionality through software modular, so the circuit in the system is simple and that makes the system stability and accuracy greatly improved.

Abstract: Track irregularities are the only external excitation in vehicle-bridge coupling vibration analysis and therefore the numerical simulation method of track irregularities is very important. The U.S. frequency spectrum is usually employed to simulate the track irregularities in China. In this paper, the secondary filtering method is introduced to the simulation of track irregularities and MATLAB programing is employed to simulate an example. Based on the comparison of the simulation results and the objective function, it is indicated that the simulation result is reliable and the method is feasible.
