remanufacturing is an industrial process that makes used products reusable. remanufacturing is a way to establish a closed-loop supply chain. one of the important aspects in both reverse logistics and remanufacturing is pricing of returned and remanufactured products (called cores) that it has been noticed in this paper. in addition, in this paper the researchers have tried to present a mathema...

Explanations of human behavior are most often presented in a verbal form as theories. Psychologists can also harness the power and precision of mathematics by explaining behavior quantitatively. This chapter introduces the reader to how this is done and the advantages of doing so. It begins by contrasting mathematical modeling with hypothesis testing to highlight how the two methods of knowledg...

Joint estimation of spin density, R∗ 2 decay and offresonance frequency maps is very useful in many magnetic resonance imaging (MRI) applications. The standard multi-echo approach can achieve high accuracy but requires a long acquisition time for sampling multiple k-space frames. There are many approaches to accelerate the acquisition. Among them, singleor multi-shot trajectory based sampling h...

In describing the first-order properties of laser speckle under polarized illumination conditions, it is almost an article of faith that the contrast is unity. In many processing schemes, however, the contrast defined as the quotient of the standard deviation and the mean is calculated over a localized spatial region. In such cases, this local contrast displays a distribution of values that can...

Three-dimensional (3D) image acquisition systems are rapidly becoming more affordable, especially systems based on commodity electronic cameras. At the same time, personal computers with graphics hardware capable of displaying complex 3D models are also becoming inexpensive enough to be available to a large population. As a result, there is potentially an opportunity to consider new virtual rea...

We present a software acquisition meta-model, called SAMM, for Commercial-Off-The-Shelf (COTS) software acquisition. Our model is a meta-model in that it includes sections that use other, detailed, models for specific tasks. SAMM is a complete life-cycle model that begins with an end-user need and ends with software maintenance. We have adapted several other models in to SAMM and added several ...

This paper describes a practical system developed for generating 3D models of human heads from silhouettes alone. The input to the system is an image sequence acquired from circular motion. Both the camera motion and the 3D structure of the head are estimated using silhouettes which are tracked throughout the sequence. Special properties of the camera motion and their relationships with the int...

We describe a method for automatically generating accurate piecewise planar models of indoor scenes using a combination of a 2D laser scanner and a camera on a mobile platform. The method exploits the complementarity of the sensors. Mapping techniques applied to 2D laser scans simultaneously compute a map and the location of the sensor in the unknown environment. This provides an initial estima...

High-delity, textured geometric models are a fundamental starting point for computer graphics , simulation, visualization, design, and analysis. Existing tools for acquiring 3d models of large-scale (e.g., urban) geometry from imagery require signiicant manual input and suffer other, algorithmic scaling limitations. We are pursuing a research and engineering eeort to develop a novel sensor, and...
