In this contribution, we obtain self-similar propagation of high-energy, ultrashort, parabolic pulses in a passively mode-locked Yb-doped fiber laser by numerical simulation using our non-distributed model. For extracting the chirp of these wave-breaking-free self-similar solitons to research characteristics of them, we propose several methods to accomplish the extraction and then discuss the advantages and disadvantages of these time-frequency analysis methods in this particular application.

Resource Arbitration and allocation are some of the very critical management issues in cloud computing, because IT services are to be provisioned on subscriptions based on the consumer computing requirements. Enabling the optimal utilization of the requested resources by the consumers is a challenge, and any failure of it can possibly lead to a serious performance degradation of the cloud system. Here, we focus on the dynamic distribution and optimal utilization of the resources in the cloud architecture in a specific time period. We have proposed a Rule Based Resource allocation model (RBRAM) along with a Supply-Demand analysis of the resources in a time marching paradigm. Within the framework of this approach, the analysis shows an improved performance of the system, achieved through efficiently allocating the resources to the jobs submitted to the cloud.

Real-time clothing animation has wide applications in many areas such as the design industry and e-commerce. Existing cloth simulation techniques based on the physical model can produce realistic animation effect. But they often incur a high computational load and hence are very time-consuming. GPU has become more widely used for high performance computing for its parallel processing capability. However, in the clothing animation problem, some tasks may not be suitable for GPU. In order to achieve the real-time realistic animation effect, this paper proposes a CPU-GPU hybrid computing framework. It is found that this framework can significantly improve bandwidth utilization. In this framework, the GPU is mainly in charge of high level parallel modules such as force calculation, collision detection and position update for each cloth vertex, while the CPU deals with the serial over-stretching process and other related computing. The implemented system achieves 10 times performance increase compared to the CPU mode, and can generate about 100 clothing animation key frames per second, thus meeting the real-time requirement for clothing animation.

Google's MapReduce enables program automatic parallelization by partitioning input data and replicating functions, but it does not directly support complex parallel modes like pipeline. However, many parallel modes are helpful to optimize solution of parallel computing problem. In this paper, we propose EFC (Execution Flow Control), a novel programming model and related implementation. It supports an execution-flow control interface which makes the model more compatible with different parallel modes. It allows user to modify execution flow as needed. The new model enables simple compact design of most parallel modes.

COA (Course of Action) planning involves resource allocation and task scheduling. Traditionally, this problem is tackled with the assumption that task duration is constant and with the objective to minimize the makespan. In contrast to this, this paper assumes task duration can vary in a time interval and the objective is to maximize the RM (Robustness Measure) given the deadline, which makes sense to deal with the duration uncertainty. A COA planning method based on GA (Genetic Algorithm) and STN (Simple Temporal Network) is proposed and a COA planning instance is presented to illustrate the usefulness of this method.

The theory of asymmetric λ/2 coupling filter is presented. According to the both coupling modes of electric and magnetic, two novel coplanar waveguide (CPW) structure filters, the center frequency is 60GHz, is obtained based on the theory of asymmetric λ/2 coupling. The harmonic suppression technology is introduced in the design process. The parasitic frequency and second harmonic are effectively suppressed by the harmonic suppression technology. The bandwidth of the electric coupling filter is 1.5GHz and the insertion loss is 0.6 dB. The bandwidth of the magnetic coupling filter is 12GHz and the insertion loss is 0.3 dB.

We simulate a presently proposed PZT (piezoelectric transducer) driver circuit with relatively good dynamic response characteristics using a kind of electronic circuits simulation software — Multisim2001. We study the dynamic response characteristics and the power of this circuit. The simulation results shows that this PZT driver circuit can synchronously and linearly amplify the low voltage of the input dynamic signal such as sinusoidal wave to high voltage required for driving PZT, and the correlation coefficient between the input and output voltage is as high as 0.9934, calculated from the experiment data. Furthermore, we found that the power supplied by the power supply increases from 5.353 Watts to 7.854 Watts as the PZT capacitance increases from 100 nF to 1000 nF. By drawing figures and calculating the correlation coefficient between the power and the PZT capacitance (which is 0.99978), we can see that the power is perfectly direct proportional to the capacitance. To our knowledge it's the first time to note this correlation between the power and the PZT capacitance. This conclusion is very helpful for practical PZT driver circuits design.

Knowledge discovery has often used as a background application to motivate many technical problems in ETL research. However, traditional ETL tools face new challenges include tremendous amount of data and limitation of computing ability and so on. Meanwhile, MapReduce parallel computing model has been widely used in recent years. In This paper, we first analyze the problems of existing ETL tools and propose a metadata-driven ETL service model, and then summarize the types of metadata and their application scopes. Based on this metadata-driven ETL service model, we put forward a concrete ETL framework combined ETL with MapReduce algorithm framework and provided as PaaS to meet the requirements. Afterwards, many significant services are also discussed. At last, we illustrate some strategies for advancing the flexibility, extensibility of the framework and promote the reusability of ETL components and ETL application. In conclusion, practices have proved that the model and the framework proposed in this paper have advantages that open-source or commercial ETL tools do not have and can deal the problem of processing large scale data.
