Comparisons of STRETCH meat grinders based on two different topologies of ICCOS

Journal of Beijing Institute of technology 2013年第4期22卷 432-439页

作者：刘辉毕世华李军刘培柱陈阵 School of Aerospace Engineering Beijing Institute of Technology Science and Technology on Complex Land Systems Simulation Laboratory

Inductive energy storage systems （IES）require opening switches which are technically much more difficult to realize than closing switches. Institute of Advanced technology （ IAT ） puts forward a meat grinder with an inductive pulse power topology called slow transfer of energy through capacitive hybrid （STRETCH）. In this topology, an integrated gate-commutated thyristor （IGCT） is capable of breaking the charging currents on the order of 4 kA, and it may encounter difficulties in expanding to higher energy systems. German-French Institute of Saint Louis （ISL） has developed a high-power opening switch based on standard high-power thyristors by using their so-called inverse current commutation with semiconductor devices （ICCOS） countercurrent commutation principle. Two topologies of the STRETCH meat grinder with ICCOS are analyzed. And they are compared based on the voltage across the main switch, the current multiplication factor and other aspects by u- sing Matlab simulations. The advantages and disadvantages of the two topologies are shown through the comparisons. Therefore a more suitable topology can be chosen for realistic applications accord- ing to their performances.

In this paper, an unified information description model ("UIDM" for short) is proposed to model information from multiple sources in the Information Grid uniformly. In the UIDM: 1) An unified information description language derived from the ODLI 3 is presented to describe information uniformly to resolve the information heterogeneity;2) A set of diagrammatized information modeling symbols are defined to model the information diagrammatically to illustrate the semantic relationships between information classes;3) An information capability model is advanced to model the capability of information from different information sources, based on which the high-performance global views for information sharing are to be constructed. © (2013) Trans Tech Publications, Switzerland.

We present a markerless augmented reality(AR) system based on 3D model. First, the feature of environment was extracted using SIFT operator, then the method of stratified reconstruction was used to reconstruct the 3D scene, after that we constructed the database of prior knowledge using the KDTree. Finally, we tracked the 3D model based on these prior knowledge via feature matching and pose estimation in real time. Experimental results demonstrated that this method is sufficient for markerless tracking registration. With the prior knowledge, key frame selection problem can be avoided and the running speed is also increased. © Springer-Verlag 2013.

For the parameter estimation problem of inertial instrumentation error models, a Bayesian network is founded to fuse the calibration data and make error coefficients statistical inference in this paper. First the fundamental of Bayesian network is stated and then how to establish network for a typical case of inertial instrumentation error coefficients estimation is illustrated. Since the difficult high-dimension integral calculus for model parameter can be avoidable, WinBUGS software based on MCMC method is used for calculation and inference. The simulated results show that using Bayesian network to make statistical inference for inertial instrumentation error model is reasonable and effective. © (2013) Trans Tech Publications, Switzerland.

Metastable States and Wetting Transition of Submerged Superhydrophobic Structures

Superhydrophobicity on structured surfaces is frequently achieved via the maintenance of liquid-air interfaces adjacent to the trapped air pockets. These interfaces, however, are subject to instabilities due to the Cassie-Baxter-to-Wenzel transition and total wetting. The current work examines in situ liquid-air interfaces on a submerged surface patterned with cylindrical micropores using confocal microscopy. Both the pinned Cassie-Baxter and depinned metastable states are directly observed and measured. The metastable state dynamically evolves, leading to a transition to the Wenzel state. This process is extensively quantified under different ambient pressure conditions, and the data are in good agreement with a diffusion-based model prediction. A similarity law along with a characteristic time scale is derived which governs the lifetime of the air pockets and which can be used to predict the longevity of underwater superhydrophobicity.

The load balancing problem is becoming the main technical obstacle in HLA distributed simulation development with the increasing scale of distributed simulation system. The solution of task-federate mapping and federate-processor mapping used to be determined based on experiences and the entity is taken as a task granularity in simulations in order to simplify the model in previous studies. Neither the experience methods nor the previous studies could solve the huge communication overhead or load imbalance problem effectively in large scale distributed simulation. The static load balancing optimization of HLA distributed simulation is divided into task-federate mapping and federate-processor mapping, and a two-stage mapping allocation optimization method is proposed in this paper. Decreasing communication overhead of the system is the main mission in the taskfederate mapping stage and the load balancing is studied in the federate allocation stage. The effectiveness of the proposed method, which developed a new direction for static load balancing distribution optimization in distributed simulations, is verified with experiments.

An iterative space alternative tiling parallel algorithm for 3D finite difference stencil computations

International Journal of Database Theory and Application

International Journal of Database Theory and Application 2014年第6期7卷 105-120页

Stencils are finite-difference algorithms for solving large-scale and high-dimension partial differential equations. Due to the data dependences among the iterative statements in Stencils, traditional Stencil computations are be executed serially, rather than in parallel. It's challenging to design an effective and scalable Stencil parallelized method. To address the issue of 3D data space computing, we present a serial execution model based on multi-layers symmetric Stencil method and time skewing techniques. Within this model, the iteration space is divided to multiple tiles based on time skewing, where the executive process is ordered by the sequence of tiles, and the nodes in each individual tile can be swept repeatedly to improve the data locality. In addition, we propose a novel 3D iterative space alternate tiling Stencil parallel method, which subdivides the iteration space along high dimension, and changes the execution sequence of tiles to reduce the data dependency and communication cost, where the partial order of tiles is still guaranteed. Experimental results demonstrate our proposed alternative tiling parallel method achieves better parallel efficiency and scalability compared with the domain-decomposition methods.
