This paper describes B-spline interpolation and compares it with other reconstruction methods, especially in three-dimensional space. We first consider the B-spline bases in the terms of convolution in signal processing. The presented analysis requires careful usage of continuous and discrete representation of B-spline. Emphasis is given to the important difference between B-spline interpolation and approximation. The difference is shown through frequency domain analysis, so we derive frequency responses of the B-spline interpolation and approximation. We conclude by demonstrating the use of several reconstruction filters and appropriate gradient estimators in volume rendering. Exact reconstruction in volume visualization is very important in many industrial applications, such as material cavity control.

The B-spline interpolation in visualization

The volume data is generally in the form of the large array of numbers. In order to render the object hidden in the volumetric data, we need to reconstruct or interpolate data values between the samples. The novelty presented in this paper is B-spline interpolation in the volumetric space. We show that this approach is better than currently used methods. We also present a hybrid approach, analyze this approach in frequency domain and compare it to B-spline interpolation. To enhance the quality during the volume visualization process it is important to enhance the quality of the reconstruction. It is of crucial importance to explore different undesired effects. If better reconstruction is performed the more accurate result of volume visualization process is achieved.

The possible accuracy limit of micro control of dynamic systems in which the dominating disturbances are thermal and quantum noises is considered. The optimal control with a Kalman-Bucy filter (KBF) and physical limits of micro control of a macro object are studied. For the individual control of a micro object a quantum prototype of KBF with non-demolition observation on the basis of quantum filtering equation is introduced. © 1997 IEEE.

Annual IEEE Conference on Power Electronics Specialists (PESC)

作者： J.G. Hayes J.T. Hall M.C. Egan J.M.D. Murphy DELCO Power Control Systems Torrance CA USA Department of Electrical Engineering and Microelectronics University College Cork Ireland

In January, 1995 the Society of Automotive Engineers, Inc. (SAE) published a recommended practice for electric vehicle battery charging using inductive coupling (SAE J-1773) for use in the USA. This paper considers the case of a series-resonant power converter driving the coupling interface. The resultant topology, a four element series-parallel LLCC-type (SP-LLCC) resonant DC-DC power converter with capacitive output filter, is analyzed and the time-based modal equations are solved in steady-state by using a state-variable transformation. The analytical results are validated experimentally.

Conference Record of the IEEE Industry Applications Society Annual Meeting (IAS)

作者： J.G. Hayes S.E. Schulz J.T. Hall M.G. Egan J.M.D. Murphy DELCO Power Control Systems Torrance CA USA Department Of Electrical Engineering and Microelectronics University College Cork Ireland

The recommended practice for electric vehicle battery charging using inductive coupling (SAE J-1773), published in January 1995 by the Society of Automotive Engineers, Inc. (SAE), outlines values and tolerances for critical vehicle inlet parameters which must be considered when selecting a driving topology. The inductive coupling vehicle inlet contains a significant discrete capacitive component in addition to low magnetizing and high leakage inductances. Driving the topology with a variable-frequency, series-resonant converter results in a four-element topology with many desirable features: unity transformer turns ratio; buck-boost voltage gain; current source operation; monotonic power transfer characteristic over a wide load range; throttling capability down to no-load; high-frequency operation; narrow frequency range; use of zero-voltage-switched MOSFETs with slow integral diode; high efficiency; inherent short-circuit protection; secondary dv/dt control and current waveshaping for the cable, coupler and vehicle inlet resulting in enhanced electromagnetic compatibility.

A new methodology of R&D of micronano-robots (MNR) based on modelling of the nonlinear master dissipative stochastic equations of MNR-motion with minimum entropy production is described. The methodology includes: hierarchical levels for the description of the dynamic behavior of MNR based on laws of microphysics, an extraction of information from coherent states of MNR using quantum non-demolition (QND) measurement processes, logic of intelligent dynamic behavior, optimal control of states, and the dynamic system theory of mechanical motion. On the basis of nonlinear dissipative equations of motion a new quantum postulate for the description of MNR as open thermodynamic and quantum dynamic systems is introduced. Physical conditions for optimal intelligent control of thermodynamic and quantum systems are introduced. The intelligent thermodynamic behaviour of MNR from the artificial life point of view is described. New nonlinear mechanics with entropy exchange are used. The thermodynamic stability conditions for MNR are developed.

This paper describes the application of the boundary element method to solving two-dimensional steady slow viscous flow problems (creeping flow) in thermal silicon oxidation. The proposed method used the velocity-pressure formulation. The use of the incompressibility condition as a boundary condition and the application of the second Green's identity to transform the domain integral into a boundary integral result in a system of three boundary integral equations for velocity components and pressure. Solution of this system to be an ill-posed problem because of the presence of boundary conditions of the first kind. Two methods of regularization are employed. The numerical results for trench oxidation process are presented.

Microwave probes are used extensively for linear and nonlinear characterization of microwave devices on wafer and are commercially available for use at frequencies up to 65 GHz. An on-wafer noise measurement test system, for discrete devices, is now commercially available and on-wafer power measurement techniques are emerging slowly. These probes are also getting more recognition for the testing of packaged chips, packages, and modules. More accurate calibration techniques and their on-wafer validation are being developed. Automatic testing of MMIC wafers, using an integrated test system, is a key requirement for the development of low-cost IC production.

Both the timely manufacture of defense systems and their subsequent on-line operability depend upon the availability of component parts. The growing problem of microelectronic component nonavailability is casting a shadow over logistics support to these systems. This paper will discuss the causes of the problem and provide some examples of cases confronted by the DoD logistics community. It will also identify some actions which have been taken in the past to manage the issue as well as initiatives now underway. Finally it will look at what lies ahead.
