We present practical algorithms to compute subgroups such as Hall systems, system normalizers, F-normalizers and F-covering subgroups in finite solvable groups. An application is an algorithm to calculate head complements in finite solvable groups; that is, complements which are closely related to maximal subgroups. Our algorithms use the technique of… (More)

(Received) Let G, H and E be subgroups of a nite nilpotent permutation group of degree n. We describe the theory and implementation of an algorithm to compute the normalizer N G (H) in time polynomial in n, and we give a modiied algorithm to determine whether H and E are conjugate under G and, if so, to nd a conjugating element of G. Other algorithms… (More)

Let G and H be subgroups of a finite p-group of permutations. We describe the theory and implementation of a polynomial-time algorithm for computing the normalizer of H in G. The method employs the imprimitivity structure and an associated canonical chief series to reduce to linear problems with fast solutions. An implementation in GAP exhibits marked… (More)

In many object recognition problems, the object to be identiied is one of a xed set (library) of objects. The problem of identifying which object is present then shares characteristics of the signal detection and parameter estimation problem: which signal is present and what are its parameters? The Reciprocal Basis Set/Direction of Arrival (RBS/DOA)… (More)

Phosphorus losses from agricultural land can cause accelerated eutrophication of surface water bodies. This study evaluated the use of soil test phosphorus (STP) levels to predict dissolved inorganic phosphorus (DIP) concentrations in runoff water from agricultural soils using laboratory rainfall simulation. The objectives of this study were to determine… (More)

This document constitutes the draft text proposal for a test methodology for measuring metrics that characterize the time it takes an 802.11 client STA to transition, or " roam, " between two APs. Notice: This document has been prepared to assist IEEE 802.11. It is offered as a basis for discussion and is not binding on the contributing individual(s) or… (More)
