(a) A policy of just playing item 3. This policy has depth 1. (b) A policy that plays item 2 first. If it is small, it plays item 1 whereas if it is large it plays item 3. After this, the final item is determined due to the fact that there are only 3 items in the problem. This policy has depth 2. Figure 4: Examples of policies in the simple 3 item, 2 sizes stochastic knapsack problem. Each blue...

Digital image correlation and tracking (DIC) is an optical method that employs tracking and image registration techniques for accurate 2D and 3D measurements of changes in images. This is often used to measure deformation, displacement, strain. Intensity Integration Technique and Line summation method are one of DIC Techniques. The purpose of this research is to identify the similarities betwee...

This paper presents an approximate multiple segment line scan-conversion method — the Slope Table Method, and analyze the statistics on different properties, advantages, and drawbacks. The statistics show that the new method can increase the percentage of multiple segment lines (i.e., lines with more than one segments) of all possible lines in an N×N raster area from about 39% to more than 99%....

The primary purpose of the study was to determine the relationships between %HRR vs. %VO2R and %HRR vs. %VO2max during maximal elliptical crosstrainer (ECT) exercise. A secondary aim was to compare the %HRR vs. %VO2R and %HRR vs. %VO2max relationships between maximal ECT and treadmill (TM) exercise. Adult subjects (n = 48) completed a maximal exercise test on the ECT, with a subgroup (N = 24) a...

We derive a theoretical relation between RBLR, the size of the broademission-line region of active galactic nuclei, and the observed soft X-ray luminosity and spectrum. We find that in addition to the well known RBLR ∼ L 1/2 scaling, RBLR depends also on the soft X-ray spectral slope. Applying this relation to calculate a predicted BLR radius and emission-line width, we show that including the ...

Highlights Very fine sand is the single most important variable for predicting rill and interrill erodibility values. Slope steepness property critical shear erosion. Erodibility prediction equations with best goodness-of-fits have both soil texture mineralogy terms. Equations to predict from texture, organic carbon, cation excha...

Combinatorial auctions (CAs) are important mechanisms for allocating interrelated items. Unfortunately, winner determination is NP-complete unless there is special structure. We study the setting where there is a graph (with some desired property), with the items as vertices, and every bid bids on a connected set of items. Two computational problems arise: 1) clearing the auction when given the...

OBJECTIVE To develop a self-reported measure of the subjective impact of pressure ulcers on health-related quality of life (HRQOL) in individuals with spinal cord injury (SCI) as part of the SCI quality of life (SCI-QOL) measurement system. DESIGN Grounded-theory based qualitative item development methods, large-scale item calibration testing, confirmatory factor analysis (CFA), and item resp...
