Naval Engineers Journal 2009年第5期112卷

作者： Dr. Roy L. Streit Since 1992 Dr. Streit has focused a significant amount of his energy to assignment problems in acoustic warfare data fusion systems. This work led him to the formulation of the PDD Principle a broadly useful theoretical method that enables the derivation of new classes of discrete-continuous estimation algorithms for solving assignment problems without requiring enumeration and pruning. In recognition of his outstanding work in this area Dr. Streit received the NAVSEA Scientist of the Year Award for 1997. Dr. Streit has also been pursuing avenues for analyzing the loss in broadband detection performance of an acoustic array in the presence of interferences. Because examining all possible separations between the signal and many interferers is infeasible he has proposed a Poisson process model for the number and location (s) of the interferers. In this same time period Dr. Streit has also been investigating issues in environmental modeling and localization by proposing a novel integral method for solving the bearings-only target motion analysis problem which enables a natural heuristic for compensating for mismatch between the model predictions and the real world. Most recently Dr. Streit has proposed the Numerical ACoustic Hull ARray (NACHAR) Project as a revolutionary and ambitious approach to hull array design. Its premise is that optimizing the detection capability of large hull arrays requires the full integration of hull sensor array and beamformer design processes. Because NACHAR crosses an unusual number of technical disciplines it involves researchers from several departments. The diversity of Dr. Streif s technical background makes him uniquely suited to lead the project Dr. Streifs truly impressive scientific achievements are complemented by a noteworthy list of professional activities that accentuate his value to Division Newport and the Navy. He represents the United States in The Technical Cooperation Program Maritime Activities Panel 9 (Sonar Technology) and participates in the Division New

for his significant engineering research and development in sonar array research and acoustic transient signals as set forth in the following

This paper is concerned with the design of Multi-Inputs and Multi-Outputs (MIMO) predictive PID controllers, which have similar performance to that obtainable from model-based predictive controllers. A new PID control structure is defined which incorporates the prediction of future outputs and uses future set point. A method is proposed to calculate the optimal values of the PID gains from generalised predictive control results. A decentralized version of the predictive PID controllers is presented and the stability of the closed loop system is studied. Simulation studies demonstrate the superior performance of the proposed controller compared with a conventional PID controller. The results are also compared with generalised predictive control solutions.

Approximating the largest eigenvalue of network adjacency matrices

Physical Review E 2007年第5期76卷 056119-056119页

作者： Juan G. Restrepo Edward Ott Brian R. Hunt Center for Interdisciplinary Research in Complex Systems Northeastern University Boston Massachusetts 02115 USA Department of Physics Department of Electrical and Computer Engineering and Institute for Research in Electronics and Applied Physics University of Maryland College Park Maryland 20742 USA Department of Mathematics and Institute for Physical Science and Technology University of Maryland College Park Maryland 20742 USA

The largest eigenvalue of the adjacency matrix of a network plays an important role in several network processes (e.g., synchronization of oscillators, percolation on directed networks, and linear stability of equilibria of network coupled systems). In this paper we develop approximations to the largest eigenvalue of adjacency matrices and discuss the relationships between these approximations. Numerical experiments on simulated networks are used to test our results.

We developed a novel type of quartz tuning-fork probe that vibrates and detects its own probe deformation, for application to atomic force microscopy (AFM). This tuning-fork probe improves the AFM image resolution because of its high Q (quality) factor value. The tuning-fork probe has a sharp tip that was fabricated using anisotropic wet etching and a focused ion beam system. We evaluated the vibration properties of the tuning-fork in both the in-phase and anti-phase driving mode, and measured a Q factor value of 2808 in the anti-phase mode. We also confirmed that the tuning-fork probe is able to measure a 100 nm-step on a silicon surface by self-vibration and self-detection, without using external vibration and optical-detection mechanisms.

Thomson Avenue Cambridge CB3 0HE United Kingdom Max-Planck Institute for the Physics of Complex Systems Nöthnitzer Strasse 38 01187 Dresden Germany Faculty of Engineering Tohoku-Gakuin University Tagajyo 985-8537 Japan Institute for Materials Research Tohoku University Sendai 980-8577 Japan

We present experimental evidence, by magnetic force microscopy, for the existence of magnetic bubbles in suitably designed high-quality circular FePt nanodots. We specifically study dots of sizes where this fundamental magnetic state is a ground state and it is spontaneously created. We also observe triple-domain states consisting of concentric rings with alternating magnetization. A numerical study confirms the range of stability of the observed magnetic states and predicts the phase diagram in parameter space. Differences in the topology of these states imply distinct dynamical behavior, providing the basis for fundamental dynamical studies.

Functional modulation of power-law distribution in visual perception

Physical Review E 2007年第5期75卷 051902-051902页

Neuronal activities have recently been reported to exhibit power-law scaling behavior. However, it has not been demonstrated that the power-law component can play an important role in human perceptual functions. Here, we demonstrate that the power spectrum of magnetoencephalograph recordings of brain activity varies in coordination with perception of subthreshold visual stimuli. We observed that perceptual performance could be better explained by modulation of the power-law component than by modulation of the peak power in particular narrow frequency ranges. The results suggest that the brain operates in a state of self-organized criticality, modulating the power spectral exponent of its activity to optimize its internal state for response to external stimuli.

Primary objectives for the International Space Station (ISS) in support of the Vision for Space Exploration include conducting research to counteract the harmful effects of space on human health, test new space technologies, and learn to operate long-duration space missions. In pursuit of these objectives, NASA is interested in closer cooperation between the ISS operational community, scientists, and engineers. To develop the exploration vehicles for missions to the moon and Mars, NASA must test materials, foods, and medicines to ensure their performance in the space environment. These results will enable important decisions on the materials to be used for future space vehicles. Another critical factor for the success on future missions beyond Earth orbit is the capability for repairs of equipment. On the ISS, the practice of crewmembers performing repairs in microgravity will increase our understanding of the repair processes in space;when these capabilities are needed during future space exploration missions, we will have the knowledge and experience to perform them. The ISS is a unique and irreplaceable training ground for building the operational knowledge required to safely conduct future exploration missions, and the growing links within the science, engineering and operations communities are reinforcing the value of that training. Current interactions between the communities that support the ISS have already produced many synergies that are significantly accelerating NASA's advancement towards future exploration missions in support of the Vision.

The two goals of Nonlinear Biomedical Physics are: firstly to show how nonlinear methods can shed new light on biological phenomena and medical applications and secondly to bridge the technical, mathematical, and cultural divides between the physical disciplines where these methods are being developed and the audience for their use in the biological and medical sciences. © 2007 Czernicki et al;licensee BioMed Central Ltd.
