Simulation and visualization of NC milling processes has become an important step in computer aided manufacturing. The usage of stock materials with specific locally varying properties (like density, accuracy, color,. . . ) becomes more and more important with new technologies emerging in the material industry. Our new approach, using volumetric representation, has been adapted to this needs an...

In the past two decades, major advances have been made in the clinical evaluation and treatment of valvular heart disease owing to the advent of noninvasive cardiac imaging modalities. In clinical practice, valvular disease evaluation is typically performed on two-dimensional (2D) images, even though most imaging modalities offer three-dimensional (3D) volumetric, time-resolved data. Such 3D da...

The Pads have unique values of thermophysical properties (THP) having important contribution over heat transfer into the PCB structure. Materials with high thermal diffusivity (TD) rapidly adjust their temperature to that of their surroundings, because the HT is quick in compare to their volumetric heat capacity (VHC). In the paper is presenting the diffusivity tests (ASTM E1461 flash method) f...

INTRODUCTION Echo-Shifted Gradient-Recalled-Echo (ESGRE) can be used to rapidly acquire MR images with strong T2* sensitivity [1, 2]. In this approach, excited spins are precessing over multiple TRs before each gradient echo is recalled. Therefore, the effective T2* weighting period in ESGRE is longer than one TR (TE>TR). This property makes it attractive in various clinical applications to sig...

In “hybrid” search, observers search a visual display for any of several targets held in memory. It is known that the contents of the memory set can guide visual search (e.g., if the memorized targets are all animals, visual attention can be guided away from signs). It is not known if the visual display can guide memory search (e.g., if the memory set is composed of signs and animals, can a vis...

In this paper we describe a medical application where we exploit surface properties (measured in form of 3D-Range scans of the human back) to derive a-priori unknown additional properties of the proband, that otherwise can only be acquired using multiple x-ray recordings or volumetric scans as CT or MRI. On the basis of 274 data sets, we perform classification using statistical shape analysis m...

competition is against monopoly and intellectual property creates monopoly for intellectual property owner. this article had been paid cooperation between apparently contradictory policies. exhaustion, parallel imports, compulsory license, intellectual property exploitation contract that coincide with competition are methods of cooperation between intellectual property and competition law. comp...

In this paper, we investigate a new approach to the cooccurrence matrix currently used to extract textural features: co-occurrence matrices for volumetric data. While traditional texture metrics have concentrated on 2D texture, 3D imaging modalities are becoming more and more prevalent, providing the possibility of examining texture as a volumetric phenomenon. Just as computer graphics have use...

The measurement and compensation of volumetric positioning errors can greatly improve the accuracy of the machine tools. In this paper, a sequential step diagonal measurement is introduced to calibrate 9 volumetric positioning errors in a quick way. Measurements under various thermal conditions are preformed to understand the relationship between the volumetric positioning errors and the temper...

Volumetric registration of brains is required for inter-subject studies of functional and anatomical data. Intensity-driven registration typically results in some degree of misalignment of cortical and gyral folds. Increased statistical power in group studies may be achieved through improved alignment of cortical areas by using sulcal landmarks. In this paper we describe a new volumetric regist...
