On the performance of three-stage group screening experiments On the performance of three-stage group screening experiments
(School of Mathematics, 1987)This paper examines the performance of three-stage group screening in terms of the mean number of tests needed; and the proportion of active factors correctly detected by the screening plan, A linear cost function is also ... -
Step-wise group screening designs with errors in observations
(1987)The performance of step-wise group screening In terms of the expected number of runs and the expected number of incorrect decisions, Is considered. A method for obtaining optimal step-wise designs Is presented, for the ... -
Optimum two stage group-screening with unequal group sizes and with errors in decisions
(School of Mathematics, 1987)In this paper, the formula for the expected number of incorrect decisions has been obtained. It is assumed that the factors are defective with different a-priori probabilities. Group-screening designs have been described ... -
Optimum two stage group-screening designs
(School of Mathematics, 1984)In this paper, emphasis has been given to both the expected number of runs and the expected number of incorrect decisions and two stage group-screening designs have been obtained which minimise one fixing the other or ... -
Two stage woth unequal a-prior probabilities
(School of Mathematics, 1984)This paper aims at working out economic groupscreening plans to sort out defective items from a population which consists of tems with unequal a-priori probabilities of being defective. It is shown that in the case of ... -
Pigeonpea (Cajanus cajan) varietal response to insect podborer infestation in Kenya.
(University of Nairobi.Department of Zoology, 1980)In field trials with (a) determinate and (b) indeterminate pigeon pea cv., pod damage by Heliothis armigera, Pardasena virgulana and Melanagromyza obtusa and seed yield losses ranged from 37% and 23% in an early-flowering ... -
Computer-Controlled Apparatus for Automated Development of Continuous Flow Methods
(1989)An automated apparatus to assist in the development of analytical continuous flow methods is described. The system is capable of controlling and monitoring a variety of pumps, valves, and detectors through an IBM PC-AT ... -

Generalized relativistic dynamics in a non-inertial reference frame
(2010)Generalized relativistic field equations have been derived for dynamics in a non-inertial reference frame interpreted as a Finsler space where events are specified by both spacetime coordinates and corresponding velocities ... -

Test of QCD indū→W − γg, the radiation amplitude zero and the magnetic moment of theW boson
(Department of Physics, University of NairobiPhysics Department, Oklahoma State University, Stillwater, USA, 1985)We have calculated the differential cross-section for the processdū→W − γg (Jet). It is found that, although the radiation amplitude zero, which occurs for the lowest-order processdū→W −γ, is spoiled, there remains a very ... -
One-loop vacuum polarization in the nonlinear Rξ gauge
(1985)In the nonlinear Rξ gauge the one-loop contributions to the dynamical-gauge-field vacuum polarization are found to be separately transverse even in a spontaneously broken theory. Moreover, the theorems of DeWitt and Kallosh ... -
Some properties of green's functions in the non-linear Rξ gauge
(1984)In the non-linear Rξ gauge, the W− boson field satisfies the naive Ward identity and in consequence one-loop contributions give zero neutrino charge, which they do not in the conventional Rξ gauge. Further, in this non-linear ... -
What is the Charge Radius of the Neutrino? An Investigation in the Background Field Gauge
(Department of Physics, University of NairobiDepartment of Physics, Oklahoma State University, Stillwater, 1985)The one loop contributions to the neutrino charge radius are calculated in the background field gauge. The large logarithm term is found to be gauge invariant while other terms prove to be highly gauge dependent. It is ...
