Transient pressure waves in the vadose zone and the rapid water table response
(The Soil Science Society of America, Inc., 2013)The behaviour of a water table is important in understanding groundwater dynamics. In this 11 paper, results are presented of a disproportionate response of a water table in two distinct 12 transient pressure wave ... -
OPTIMAL RAKE RECEIVER MODEL UTILIZING TIME HOPPING IMPULSE RESPONSE ON UWB SYSTEM (WPAN)
(2016)Impulse Radio-Time Hopping-Ultra Wideband (IR-TH-UWB) is a relatively new technology that might have a big effect on improving wireless communication. This technology uses short pulses in order to transmit large amounts ... -

(Current Issues in African Tourism Research, 2017)In this time of globalization and turbulent economic environment, hotel establishments in the world are required to implement new management approaches in order to provide high quality service. Implementation of quality ... -
Relationship between gender and proactive work behaviour in the Kenya’s hotel industry
(African Journal of Tourism, Hospitality and Leisure Studies, 2017)According to Kenya National Bureau of Statistics report, (2016), wage employment by industry and sex statistics indicate a majority of males employed in the modern sector than female with accommodation and food service ... -
Do Smallholder Farmers Perceive Rainfall Variability the Same and Correctly? Gendered and Spatial Analysis of Perception Versus Actual Trends of Rainfall in Three Livelihood Zones in Kenya
(Journal of Environment and Earth Science, 2018)In this paper we compared perceived rainfall variability with actual rainfall variability using a more nuanced and mixed approach in order to understand the influence of gender dynamics and spatial location on perceptions. ... -
Evaluation of Kenyan Bentonite Clay as Geothermal Well Drilling Mud
(2015)The quest for the development of geothermal plants with capacities up to 10,000 MWe in Kenya has recently placed greater demand on bentonite clay. Bentonite clay is at present largely imported into the country at the ... -
The Performance of Step-Wise Group Screening Designs
(Sultan Qaboos University, 2015)In this paper we evaluate the performance of step-wise group screening designs in which group-factors contain an equal number of factors in the initial step. A usual assumption in group screening designs is that the ... -
MATHEMATICAL MODELLING OF HIV INFECTION
(2013)We formulate a deterministic mathematical model for the HIV/AIDS -
On Local Linear Regression Estimation in Sampling Surveys
(Pushpa Publishing House, 2017)A model based survey is employed to estimate the unknown values of the survey variable, using the local linear regression approach. In particular, a local linear regression estimator in model based surveys is studied. ... -
Mathematical Model for Detecting Diabetes in the Blood
(2011)This study presents a new mathematical model for Blood Glucose Regulatory System(BGRS) which includes epinephrine as a third variable in the form, Y˙ = AY, and whose solution has been analyzed for equilibrium and stability ... -
Impedimetry and microscopy of electrosyntheticpoly(propylene thiophenoimine)-co-poly(3,4 ethylenedioxythiophene) dendritic star copolymer
(International Journal of Electrochemical Science, 2011)The electrochemical impedance spectroscopy of generation 2 poly(propylenethiophenoimine)-co-poly(3,4 ethylene dioxythiophene) dendritic star copolymer(G2PPT-co-PEDOT) film was studied in LiClO4solution. The results show ... -
Determinants of primary school access and participation rates in the pastoralist Turkana County, Kenya
(Universal Journal of Education and General Studies, 2012)The status of education in Turkana County is typical of all the ASAL counties of Kenya characterised by low enrolments levels, high dropout rates and poor infrastructural development. This study was undertaken ... -
Robust Optimal Portfolio and Bank Capital Adequacy Management
(Research India Publications, 2018)The task of jointly estimating an optimal portfolio and bank capital adequacy ratio under model uncertainties is a real and challenging problem to portfolio managers in the banking industry. In this paper, we investigate ... -
Trustee Related Determinants of Scheme Design in Occupational Defined Contribution Schemes in Kenya
(Research Journal of Finance and Accounting, 2015)This paper aims to provide an understanding of trustee related determinants of scheme design in occupational defined contribution schemes (ODCS) in Kenya. ODCS involve no promises about the size ... -
LÉVY PROCESS BASED ORNSTEIN-UHLENBECK TEMPERATURE MODEL WITH TIME VARYING SPEED OF MEAN REVERSION
(Pushpa Publishing House, 2018)In this study we develop a Lévy process driven Ornstein-Uhlenbeck daily temperature model. The model takes into account a time dependent speed of mean reversion. It is statistically demonstrated that historical data and ... -
A Levy Regime-Switching Temperature Dynamics Model for Weather Derivatives
(2018)Weather is a key production factor in agricultural crop production but at the same time, the most significant and least controllable source of peril in agriculture. These effects of weather on agricultural crop production ... -
A Co-Integration Analysis of the Interdependencies between Crude Oil and Distillate Fuel Prices
(Scientific Research Publishing, 2018)The co-evolution and co-movement of financial time series are of utmost importance in contemporary finance, especially when considering the joint behaviour of asset price realizations. The ability to model interdependencies ... -
A Reduced Form of the Three Factor Commodity Derivative Valuation Model
(Research India Publications, 2016)This study build a reduced form of three factor valuation model by explicitly taking into account the unobservable character of the convenience yield. The spot priceprocess,theinstantaneousconvenienceyieldandCIRinterestr ... -
A Poisson-Gamma Model for Zero Inflated Rainfall Data
(Hindawi, 2018)Rainfall modeling is significant for prediction and forecasting purposes in agriculture,weather derivatives,hydrology,and risk and disaster preparedness.Normally two models are used to model the rainfall process as a chain ... -
Analyzing Expected Returns of a Stock Using The Markov Chain Model and the Capital Asset Pricing Model
