+*Clarke, I C, Brown, S, Pezzotti, G, Green, D D, T. Donaldson, T D +Loma Linda University, Loma Linda, CA [email protected] INTRODUCTION The feature that makes yttria-stabilized, tetragonal zirconia polycrystalline (Y-TZP) ceramic both strong and fatigue resistant is its ability to partially transform under stress from tetragonal phase to its monoclinic phase, i.e. an inherent metastability [1]....

Suppose there is a bag containing red balls and blue balls. You would like to estimate the fraction of red balls in the bag. However, you are only allowed to sample randomly from the bag with replacement. The straightforward method is to make T random samples and use the fraction of red balls in the random samples as an estimate of the true fraction. The question is: how many samples are enough...

When attempting to draw a ball of a specified color either from an urn containing 50 red balls and 50 black balls or from an urn containing an unknown ratio of 100 red and black balls, a majority of decision makers prefer the known-risk urn, and this ambiguity aversion effect violates expected utility theory. In an experimental investigation of the effect of urn size on ambiguity aversion, 149 ...

The tensile strength of water increases when solid particles are filtered out, and it becomes greater the smaller the remaining particles are. Natural particles are of random shape, making parametric studies on the relationship between tensile strength and particle characteristics difficult. In this investigation, using degased tap water from which natural particles larger than about 1 (m were ...

Youth is reserve force of sports development, is main force of Chinese sports further booming development sometime in the future. For Chinese three big balls, youth participation affects its development progress to a certain degree. Research youth preference way in three big balls movements’ participation is beneficial to sports teaching according to youth demands and then propel to Chinese thr...

Choosing balls which best approximate a 3D object is a non trivial problem. To answer it, we first address the inner approximation problem, which consists of approximating an object FO defined by a union of n balls with k < n balls defining a region FS ⊂ FO. This solution is further used to construct an outer approximation enclosing the initial shape, and an interpolated approximation sandwiche...

Abstract: Infants can make probabilistic inferences, inferring the composition of a sample from a population. Preschoolers and toddlers will infer a constraint on a sampling process when samples are unrepresentative of populations. In the present experiment, we asked whether 11-month-olds can use probability information to infer a physical constraint on object movement in a looking-time experim...

Objective: Rare cases of fungal balls of paranasal sinuses in children. No case has been reported in young children so far. However, allergic aspergillosis has been reported in young children. Method: A case report of 2 cases of fungal balls of paranasal sinuses in children and review of the current literature concerning fungal balls of paranasal sinuses in children are presented. Result: 2 cas...

1 Greg Kirk[Ki] raised the question of comparing the following two ways for labelling balls. Given r predetermined positive integers n i , (1 ≤ i ≤ r), and given N balls (N large), consider two ways to randomly assign r− component vectors of integers (a 1 ,. .. , a r) to them, such that 1 ≤ a i ≤ n i. We will call these vectors 'labels'. Of course altogether there are r i=1 n i possible labels....

Parts of oil spills reach Iranian coastline along the Persian Gulf in the form of tar balls and scattered oilpatches. There are many published reports regarding oil spills reaching northern coasts of the Persian Gulf,but none report on the content of heavy metals associated with petroleum in sediments and plants ofcontaminated areas. This research was conducted to determine and map petroleum- r...
