This paper describes an application of the second generation Sepia architecture implementation (Sepia-2) to support interactive visualization of scalar fields represented as very large 3D rectilinear grids. By employing pipelined sort-last associative blending operators a demonstration system yields scalable interactivity at 30 frames per second. We believe these results can be extended to supp...

This paper presents a stochastic operational optimization method for metallurgical blending processes by focusing on the uncertainty of composition of raw materials, where the stochastic optimization model is firstly formulated by explicitly incorporating uncertain parameters into the constraints as random variables. Then an efficient sampling technique is utilized to construct the expectation ...

Today's interactive 3D-applications on Pes demand efficient hardware support for functionality, e.g. shading and texture mapping. In this paper, I present an ASIC that integrates most of the 3D-reIated functionality defined in Intel's de-facto standard 3DR. As the chip was designed for real time environmental simulation systems, the main focus has been on texture mapping, which provides the mos...

In many chemical process applications, a large mix of products is produced by blending them from a much smaller set of basic grades. The basic grades themselves are typically produced on the same process equipment and inventoried in batches. Decisions that arise in this process include selecting the set of basic grades, determining how much of each basic grade to produce, and how to blend basic...

This paper deals with the problem of sensor fault tolerant control for Takagi-Sugeno nonlinear systems. Firstly, a residual generator is designed in order to detect and isolate sensor faults. Secondly, a nonlinear observer based controller, adopting the so-called parallel distributed compensation structure is designed. This controller is based on a weighted blending of the estimated states prov...

Engineering cost has been a major issue in private vocational schools leading to problems like: lack of students learning initiative like low self-learning ability, poor habit preview before lesson, attendance rate, short classroom listening time, review after insufficient investment practical training room, unreasonable teaching structure, high teacher mobility and inadequate staff. The engine...

Why did Darwin fail to develop his insights on kin selection into a proper theory of social adaptation? One suggestion has been that his inadequate understanding of heredity kept the problem out of focus. Here, I determine whether it is possible to develop a quantitative theory of kin selection upon the assumption of blending inheritance. I find that, whilst Hamilton's rule of kin selection can...

To remain an attractive model, skeleton-based implicit surfaces have to allow the design and display of shapes at interactive rates. This paper focuses on surfaces whose skeletons are graphs of interconnected curves. We present subdivision-curve primitives that rely on convolution for generating bulge-free and crease-free implicit surfaces. These surfaces are efficiently yet correctly displayed...

This paper presents a new, simple and practical algorithm to avoid artifacts when switching between discrete levels of detail (LOD) by smoothly blending LOD representations in image space. We analyze the alternatives of conventional alpha-blending and so-called late-switching (the switching of LODs “far enough” from the eyepoint), widely thought to solve the LOD switching discontinuity problem,...

Image mosaicing involves geometric alignment among video frames and image compositing or blending. For dynamic mosaicing, image mosaics are constructed dynamically along with incoming video frames. Consequently, dynamic mosaicing demands efficient operations for both alignment and blending in order to achieve real-time performance. In this paper, we focus on efficient image blending methods tha...
