In this paper, a novel view-based 3D object recognition method is proposed, which consists of three steps. First, employing wavelet transform to decompose view images of the object into different frequency sub-images. Second, for each sub-image, the features are extracted using singular-value decomposition (SVD) approach, and the features extracted from sub-images are combined to construct the feature vector of the original image. Third, the feature vector is fed into the support vector machine (SVM) to classify the objects. Experimental results show that the proposed method is effective.

It has been found that some huge overshoot in the sense of sup-norm may be observed when typical iterative learning control (ILC) algorithms are applied to LTI systems, even though monotone convergence in the sense of λ-norm is guaranteed. In this paper, a new ILC algorithm with adjustment of learning interval is proposed to resolve such an undesirable phenomenon, and it is shown that the output error can be monotonically converged to zero in the sense of sup-norm when the proposed ILC algorithm is applied. A numerical example is given to show the effectiveness of the proposed algorithm.

In 1928, the Institute of Radio Engineers (IRE) selected Jonathan Zenneck as the recipient of its Medal of Honor. He was cited for "his contribution to original researches in radio circuit performance and to the scientific and educational contributions to the literature of the pioneer radio art." His research interests included cathode-ray tube instruments, coupled resonant circuits, and directive antennas. He also performed experimental and theoretical investigations of electric wave propagation over land and water surfaces. He authored about 200 technical papers and two influential books on electric waves and wireless communication. He became a Fellow of the IRE in 1914.

We consider a system of agents as a layer between services and the network hosts. We present a self-organizing system of agents able to offer services with an increase of the speed, and decrease of the network traffic. A coordination model defines how the agents interact, and how their interactions can be controlled;this includes dynamic creation and destruction of agents, control of communication flows among agents, control of spatial distribution of agents, as well as synchronization of actions over time. Various distances and topological relations are used to explain our self-organizing mechanism. We analyze the stability of the system, and provide a new result regarding a weak form of stability depending only on the moment of the first requests of agents by hosts. Finally we provide a visualization of the services evolution using self-organizing maps, and presenting a service clustering structure.
We introduce asynchronous dynamic pushdown networks (ADPN), a new model for multithreaded programs in which pushdown systems communicate via shared memory. ADPN generalizes both CPS (concurrent pushdown systems) [QR05...

Clemson South Carolina in December 1994. Upon graduation he remained at Clemson University and received the M.S. degree in Electrical Engineering in 1997. During this time he also served as a research/teaching assistant. His research work focused on the design and implementation of various nonlinear control algorithms with emphasis on the induction motor and mechanical systems with friction present. He is currently working toward his Ph.D. degree in Electrical Engineering at Clemson University. Darren M. Dawson was born in 1962
in Macon Georgia. He received an Associate Degree in Mathematics from Macon Junior College in 1982 and a B.S. Degree in Electrical Engineering from the Georgia Institute of Technology in 1984. He then worked for Westinghouse as a control engineer from 1985 to 1987. In 1987 he returned to the Georgia Institute of Technology where he received the Ph.D. Degree in Electrical Engineering in March 1990.

In this paper, we extend the observer/control strategies previously published in [25] to an n -link, serially connected, direct drive, rigid link, revolute robot operating in the presence of nonlinear friction effects modeled by the Lu-Gre model. In addition, we also present a new adaptive control technique for compensating for the nonlinear parameterizable Stribeck effects. Specifically, an adaptive observer/controller scheme is developed which contains a feedforward approximation of the Stribeck effects. This feedforward approximation is used in a composite controller/observer strategy which forces the average square integral of the position tracking error to an arbitrarily small value. Experimental results are included to illustrate the performance of the proposed controllers.
