TbDyFe is a rare earth-iron magnetostrictive alloy with “giant” magnetostrain, good magnetomechanical coupling factor and fast response. Giant magnetostrictive actuators (GMAs) are designed and fabricated with home-made TbDyFe rods. Their magnetostrain properties under varied operation are tested. The static output displacement up to 100μm and output force up to 1500N were obtained. The dynamic displacement increases with amplitude under fixed frequency and decreases with frequency under fixed amplitude generally. The maximum dynamic output displacement of 146µm was obtained at natural frequency around 5Hz. Active vibration control employing GMA was implemented in the flexible structure. The excellent damping effect, 20-30 dB under the frequency range from 10Hz to 100Hz was obtained. The dynamic phase delay of GMA has been analyzed. A novel improved FSLMS algorithm is proposed to achieve a better control performance.

Why care about painting as an art? Does it offer to engage our aesthetic interest in ways that other art forms do not, or does it merely reproduce the aesthetic satisfactions they provide? Most paintings involve both marks on a surface, and something represented by those marks. Some attempts to say what is distinctive about painting concentrate on the former feature, understanding the art as an exploration of the two-dimensional picture plane. Others concentrate on the representational aspect, seeking to find something special about the things painting can represent, or the way in which it achieves this. The most promising approaches acknowledge both aspects, and do so as essential elements in the experiencewe have of painting. One such approach turns on the idea that the configurational aspect ‘inflects’ the representational, so that what we see in the picture itself somehow involves the marks from which the painting is composed. Another sees painting as offering aesthetic values found elsewhere, but in a distinctive form. Taking seriously the idea of our experience of painting also helps us to say something about a set of paintings we are otherwise in danger of ignoring - abstract works.

Conceptual Formulation

The tutorial presents 3D visualization as implemented at NCMI: beginning with a brief overview of the history and philosophy of scientific visualization, proceeding to a description of general methodologies used throughout the field of visualization, and concluding with specific applications in electron microscopy, confocal microscopy and x-ray diffraction. The majority of the tutorial uses biological examples of visualization to demonstrate concepts and tools.History and Philosophy: Effective scientific visualization presents data in a simple, accurate conceptual formulation. Over the last one hundred years there has been a sea change in its economics caused by digital computers: beginning with calculated tables that were manually plotted, proceeding to two dimensional image graphics, and most recently multivariate 3D interactive graphics. The capability of scientific visualization has been greatly facilitated by the evolution of computers; particularly over the last ten years the 3D visualization of biological structures is quickly becoming a necessity for analysis, conceptualization, and presentations.

Periodically driven strictly dissipative nonlinear oscillators in general possess a recurring bifurcation structure in parameter space. It consists of slightly modified versions of a basic pattern of bifurcation curves that was found to be essentially the same for many different oscillators. The periodic orbits involved in these bifurcation scenarios also possess common topological properties characterized in terms of their torsion numbers and the way they are connected when parameters are varied. In this paper, this typical bifurcation structure of periodically driven strictly dissipative oscillators will be presented and discussed in terms of examples from Duffing’s equation. Furthermore a family of two-dimensional maps is given that models (strictly) dissipative oscillators and shows essential features of the bifurcation pattern found.

The Relationship

Embedded giant magnetostrictive actuator (EGMA) is one of the most important applications of magnetostrictive material. Giant magnetostrictive actuators can deliver big-output displacement and can be driven at high frequencies. These characteristics make them suitable for a variety of positioning. However, because of the limitation of structure, the drive coil and EGMA cannot be any size as needed, so how to maximize the displacement in the limitative situation by optimization becomes the key of design. Several methods are available in the literature, but the coupling drive magnetic field of EGMA and its matrix material is often ignored. In fact, there was a close relationship between the matrix material and the distribution of drive magnetic field. To analyze the relationship, this paper establishes the magnetic circuit model for EGMA. The simulation of the coupling drive magnetic field is also presented. Finally the assumption is validated through experimental tests carried out with two different matrix materials.

Nineteenth century arithmetic is used to study periodic orbits of Anosov diffeomorphisms of the two-dimensional torus. We find that the period of the orbits, as well as their dynamical behaviour, are intimately related to the way ideals factorize in algebraic number fields.

image is a two dimensional capacity f(x, y). The way toward dividing an image into numerous parts or questions is named as Segmentation. There are two noteworthy deterrents in sectioning an image i.e., Intensity Inhomogeneity and Noise. As a result of these challenges, precise division comes about can't be acquired. This paper presents Local Chan-Vese (LCV) alongside some enhancement methods for minimization of vitality capacities to defeat power inhomogeneity and commotion. By consolidating this implanted approach, the images with force inhomogeneity can be effectively divided.
