A model predictive, dynamic control allocation algorithm is developed in this paper for the inner loop of a re-entry vehicle guidance and control system. The purpose of the control allocation portion of the guidance and control architecture is to distribute control power among redundant control effectors to meet the desired control objectives under a set of(More)
We discuss the work of the QCDSP collaboration to build an inexpensive Teraflop scale massively parallel computer suitable for computations in Quantum Chromodynamics (QCD). The computer is a collection of nodes connected in a four dimensional toroidial grid with nearest neighbor bit serial communications. A node is composed of a Texas Instruments Digital(More)
In this paper, the problem of control allocation – distribution of control power among redundant control effectors, under a set of constraints – for the inner loop of a re-entry vehicle guidance and control system is studied. Our control allocation scheme extends a previously developed model-predictive algorithm by providing asymptotic tracking of(More)
The classification of EEG tasks has drawn much attention in recent years. In this paper, a novel classification model based on independent component analysis (ICA) and Extreme learning machine (ELM) is proposed to detect lying. Firstly, ICA and its topography information were used to automatically identify the P300 ICs. Then, time and frequency-domain(More)
The CREST is an open source automatic test generation tool for C which based on Common Intermediate Language and Yices. One of its major advantages is that several heuristic search strategies are proposed to test larger programs. The success of CREST should be attributed to static instrumentation, concolic execution, and heuristic search. Thus, it's(More)
With the development of virtualization technology, it is a prevailing trend that users deploy highly reliable, scalable, high efficiency application services via virtual machines. OpenStack, the most fiery open-source virtual machines management platform, focuses on IaaS(Infrastructure as a Service), and now expands to PaaS(Platform as a Service) and(More)
Recent success deployment of P2P streaming can provided hundreds of media channels of users at any given time. This evokes an interesting question can the streaming server allocate channel resources efficiently with limited capabilities? In this paper, we propose an auction-based new strategy for resources allocation. The mechanism enable streaming server(More)

An image fusion algorithm based on Self-Generating Neural Networks¿SGNN¿ is presented in this paper. Three features are defined and proved to indicate the clarity of an image block. These features are extracted and fed into the neural networks, which learn to produce a Self-Generating Neural Tree (SGNT) to determine the clustering result. registered source(More)
