k-BARYCENTRIC OLSON CONSTANT

Let G be a finite Abelian group of order n. A k-sequence in G is said to be barycentric if it contains an element which is the “average” of its terms. The kbarycentric Olson constant BO(k, G) is introduced as the minimal positive integer t such that any t-set in G contains a k-barycentric set. Conditions for the existence of BO(k, G) are established and some values or bounds are given. Moreover...

An Improvement on Olson

We prove that for a prime number p greater than 6000, the Olson's constant for the group Zp ⊕ Zp is given by Ol(Zp ⊕ Zp) = p − 1 + Ol(Zp).

Statement Edwin Olson

Despite the apparent computational advantages that robots have in processing sensory data, they cannot match the performance of humans even on relatively simple tasks. These shortcomings have real costs. Lives are lost on civilian highways and during military operations. The scientific return of Martian landers is reduced by the need for human intervention. In homes, businesses, and health care...

Giardiasis and Cryptosporidiosis M . E . Olson

Giardia duodenalis and Cryptosporidium parvum are parasitic protozoans and infections are common in domestic ruminants. Infections can lead to moderate to severe diarrhea with occasion mortalities. Clinical disease with Cryptosporidium parvum occurs in calves between 1 and 3 weeks of age lasting 1-2 weeks in duration. Giardiasis is observed in calves older than 3 weeks of age and is chronic. Th...
