(a) Find P{X10 = 10}. (b) Approximate P{−10 ≤ X100 ≤ 10} using the central limit theorem. (c) Find P{Xn = k}. 2. Absolute-value random walk. Consider the symmetric random walk Xn in the previous problem. Define the absolute value random process Yn = |Xn|. (a) Find P{Yn = k}. (b) Find P{max1≤i<20 Yi = 10 |Y20 = 0}. 3. A random process. Let Xn = Zn−1 + Zn for n ≥ 1, where Z0, Z1, Z2, . . . are i....
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
Using an aqueous two-phase system comprised of dextran and polyethylene glycol, this article describes the stable spatial patterning of sub-microlitre droplets of bacterial suspensions. Microdroplets of different types of bacterial populations are positioned and maintained adjacent to each other without significant dispersion even though the bacteria are in suspension and not surface bound. Sma...
the purpose of this study was to determine the prevalence of bovine leukemia virus (blv) in khorasan razavi and khorasan shomali provinces which are the main provinces located in the northeast of iran. total number of 429 blood samples were collected from industrial dairy herds. the samples were categorized based on province, age (2-3, 4-6, and 7-10 years old), calving (≤ 2, 3-5, and > 5) and h...
