The Exponentially Modified Gaussian Function as a Tool for Deconvolution of Astroparticle Physics data.
(Kabarak University, 20181023)In the period 2004 – 2012, the Pierre Auger Observatory has recorded more than two million of ultrahigh energy cosmic rays. In seeking to interpret the data recorded for the events, it is necessary to simulate the interaction ... 
On norm preserving conditions for local automorphisms of commutative banach algebras
(JOOUST, 6/24/2015)The history of commutative algebra first appeared in 1890 by David Hilbert which was then followed by Banach spaces in 1924 since localization reduces many problems of geometric special case into commutative algebra problems ... 
Norms and numerical radii inequalities for ( , )  normal transaloid operators
(JOOUST, 6/24/2015)The studies on Hilbert spaces for the last decade has been of great interest to many mathematicians and researchers, especially on operator inequalities related to operator norms and numerical radii for a family of bounded ... 
Norms of derivation associated with idempotents and unitary operators
(6/24/2015)The study of operators has continued to attract the attention of many researchers. Of special interest are the calculations of norms of these operators. Johnson Stampfli wrote a paper on the norms of derivation on algebra ... 
Norm estimates for convexoid operators
(JOOUST, 6/24/2015)Hilbert space operators are important in formulation of principles of quantum mechanics and also in other fields of applied sciences. These operators include normal operators, hyponormal operators, normaloid operators, ... 
Certain properties of normaloid operators
(JOOUST, 6/24/2015)In this paper we establish new conditions for contractivity of normaloid operators. We employ some results for contractivity due to Furuta, Nakomoto, Arandelovic and Dragomir. A particular generalization is also given. 
On shift of mindset: the importance of change of mindset in helping students get better at getting better in mathematics
(JOOUST, 6/24/2015)That mathematics is important in enhancing creativity, innovativeness and technological development is undisputable. Kenya like any other African country is endowed with reach human resource yet lesscompetitive ... 
On numerical radius attainability for normal selfadjoint operators
(JOOUST, 6/24/2015)The numerical range and numerical radius are very useful in studying linear operators acting on Hilbert spaces. The operators include normal, hyponormal, normaloid, transaloid, selfadjoint, subnormal, compact and unitary. ... 
Ecological niche modelling and spatial distribution of rift valley fever vectors in Baringo County, Kenya
(JOOUST, 20150624)The Rift Valley fever (RVF) is a vectorborne zoonotic disease that has an impact on human health and animal productivity. It is caused by the Rift Valley Fever Virus (RVFV) which is primarily transmitted by flood water ... 
An automatic teller machine for HIV test based on digital image processing techniques
(JOOUST, 20150624)Many kinds of HIV testing kits have recently become available to be used in determining whether an individual's blood contains HIV virus or not. In the determine method of the HIV rapid test procedure, when a drop of blood ... 
Status of phytoplankton community of Kisumu bay, Winam gulf, Lake Victoria, Kenya
(JOOUST, 20150624)Lake Victoria has undergone remarkable and diverse ecological perturbations which are as a result of physical, chemical and biological processes, together with human activities that take place in the watershed area and ... 
Policy implications to the socioeconomic analysis of adoption determinants of new agricultural technologies in Kenya: the case of south western Kenya region
(20150624)Effective agricultural development requires equal contributions from research, extension, and the farmer. Agrowing concern among agricultural development researchers is that the farmer has often been side lined withmany ... 
Small scale production of cricket and black soldier fly for sustainable food and feed
(JOOUST, 20150624)It is estimated that by the year 2050, the world population will reach 9 billion. With the current global food insecurity, there is likelihood that the situation may worsen. The poster presentation illustrates the simple ... 
The concentrations of zinc, magnesium and iron in some selected medicinal plants used by the Chuka community in Kenya
(JOOUST, 20150624)Medicinal plants are essential components of primary health care, especially for rural communities in developing countries. The medicinal plants contain mineral elements that are beneficial therapeutically. ... 
Genetic and symbiotic characterization of root nodule symbionts of Bambara groundnuts (vigna subterranea l. verdc) and soybeans (glycine max l. merr) from selected sites in lake Victoria basin, western Kenya.
(JOOUST, 20150624)Low soil nitrogen (N) is the most limiting soil factor for sustainable high crop yields in smallholder farming systems in East Africa. Inorganic fertilizers are rarely used due to high costs and inaccessibility. Judicious ... 
Analysis and prediction of battery operating state in Kenyan solar home systems
(JOOUST, 6/24/2015)Solar power is a valuable source of electrical energy for users in the developing countries, yet many solar home systems are working at indeterminate conditions, much to the dissatisfaction of the users. Lead acid batteries ...
