This paper has four goals: (a) relate ladder height distributions to option values; (b) show how Laguerre expansions may be used in the computation of densities, distribution functions and option prices; (c) derive some new results on the integral of geometric Brownian motion over a finite interval; (d) apply the preceding results to the determination of the distribution of the integral of geom...
This paper studies a geometric-process maintenance-model for a deteriorating system under a random environment. Assume that the number of random shocks, up to time , produced by the random environment forms a counting process. Whenever a random shock arrives, the system operating time is reduced. The successive reductions in the system operating time are statistically independent and identicall...
Floating breakwaters are good alternative to the so-called fixed base breakwaters, which, in addition to having the main purpose of protecting the beach from waves, also maintain the water connection between the sea and the protected area. Researchers in order to increase the efficiency and increase the performance range of floating breakwaters, have done many researches on their effective para...
We consider samples of n geometric random variables (Γ1, Γ2,. .. Γn) where P{Γj = i} = pq i−1 , for 1 ≤ j ≤ n, with p + q = 1. The parameter we study is the position of the first occurrence of the maximum value in a such a sample. We derive a probability generating function for this position with which we compute the first two (factorial) moments. The asymptotic technique known as Rice's method...
In the present work the reflection behavior and the color appearance of acrylic yarns, as pile yarns used in carpet and pilled fabrics, are considered along their lengths as well as their cross- sections. Differences between longitudinal and cross-sectional reflection behaviors of yarns are measured in different yarn densities and hues and explained by the geometric model. The results of experi...

pared to all other ST intercepts. Seven ST were not different (P>.05) from the median intercept with an average geometric intercept (GI) of 0.20 (AZ, CA, KA, MN, OR, PA, WA). Three ST had a higher average GI of 1.00 (UT, ID, NE), two ST had a lower GI of 0.95 (IL, NY) and two ST had the lowest GI of 3.08. Average GI weighted for the observations in each group was -.19. The slope of ADF versus N...

Inductively coupled plasma mass spectrometry (ICP-MS) has been used for the determination of (232)Th and (238)U in urine of unexposed Jordanian subjects living in six cities. The range of (232)Th excretion in all subjects was found to be 1.4-640 microBq d(-1) with an average of 34.8 microBq d(-1) (geometric mean 15.8 microBq d(-1)). Results showed no statistically significant correlation with a...
