Analytical model for childhood pneumonia, a case study of Kenya

Ngari, Cyrus G.; Pokhariyal, G. P.; Koske, J. K. (Science Domain International, 2016)

Pneumonia is an infection of the lungs that is caused by bacteria, viruses, fungi, or parasites. For a long time to the best of our knowledge there have not been reliable mathematical model for childhood pneumonia in ...
Aperture Maximization with Half-Wavelength Spacing, via a 2-Circle Concentric Array Geometry that is Uniform but Sparse

Kinyili, Musyoka; Kitavi, Dominic Makaa; Ngari, Cyrus Gitonga (Journal of Advances in Mathematics and Computer Science, 2019-05-25)

This paper proposes a new sensor-array geometry (the 2-circle concentric array geometry), that maximizes the array’s spatial aperture mainly for bivariate azimuth-polar resolution of direction-of-arrival estimation ...
Application of Marks to Computation of Ranks and Subdegrees of the Symmetric Group Acting on Ordered 4-Element and 5- Element Subsets

Kimani, Patrick; Rimberia, Jane; Muthoka, Geoffrey; Lao, Hussein; Kimani, Jacob (UoEm, 2015)

Ranks and subdegrees can be computed using combinatorial arguments, the Cauchy-Frobenius lemma and use of the concept of marks. However the concept of Marks has been given very little attention. In this paper we will apply ...

Application Of Multiple Circular-Linear Regression Models To Animal Movement Data With Covariates

Mutwiri, Robert M. (2016-04)

In a many biological and physical sciences studies, a set of techniques have been developed to analyse the relationship between the circular and linear data derived from the geographical positioning system (GPS) telemetry ...
Approaches for Testing Uniformity Hypothesis in Angular Data of Mega-Herbivores

Mutwiri, Robert M.; Mwambi, Henry; Slotow, Rob (2016-03)

Circularstatistics is an area not used verymuch by ecologists to describe animal movement patterns.Nevertheless,the connection betweenthe evaluation of temporalrecurring events and theanalysis of directional data haveconverged ...
An Assessment framework for Internet banking system reliability

Musyoka, Faith M. (2014-09)

E-banking technology is very widespread in banking sector while in Kenya; banks are striving to achieve social and economic development. Banks are investing in Internet for better financial services to their customers ...
An Assessment of Suitable and Affordable Smart armband for preeclampsia Management in Antenatal Care

Musyoka, Faith M.; Thiga, Moses M.; Muketha, Geoffrey M. (2019-06)

Blood pressure is one of the measurements that is taken during antenatal care visits. Though motherhood is a fulfilling experience in the society, it is connected to ill-health and even death in some women leading to ...

Gakii, Consolata; Jepkoech, Jennifer (2019-06)

A classification algorithm is used to assign predefined classes to test instances for evaluation) or future instances to an application). This study presents a Classification model using decision tree for the purpose of ...
Cramer-Rao Bound of Direction Finding Using a Uniform Hexagonal Array

Ndiritu, Grace Wakarima; Kitavi, Dominic M.; Ngari, Cyrus G. (2019-06)

Direction-of-arrival (DOA) estimation is a key area of sensor array processing which is encountered in many important engineering applications. Although various studies have focused on the uniform hexagonal array for ...
Cramer-Rao Bound of Direction Finding Using Uniform Arc Arrays

Nyokabi, Veronicah; Kitavi, Dominic M.; Ngari, Cyrus G. (2019)

Direction-of-Arrival estimation accuracy using arc array geometry is considered in this paper. There is a scanty use of Uniform Arc Array (UAA) in conjunction with Cram er-Rao bound (CRB) for Direction-of-Arrival estimation. ...
