#### State space models and estimation of missing observations in time series

(2012-02-24)

In this project we have considered a non-linear time series model, which encompasses several standard non-linear models for time series as special cases. It also offers two methods for estimating missing observations, one ...

#### Finding the distribution of a random variable from its moment function

(2012-02-24)

Consider the problem of r + l randomly distributed points in a unit n-ball and the convex hull created by these points. Let “ n" be r! Times the r-content of an r-simplex whose p vertices are in the interior and r + 1-p ...

#### Weibull model for dose response data and akaike information criterion for model selection

(2012-02-28)

Statistical linear models are used to study dose response models in the bioassay. These have given rise to many statistical problems since the dose response data do not follow linear model. This has led to the use of ...

#### Some contributions on the use of auxiliary information in sample surveys.

(2012-02-28)

In this project, we assume that we have a population from which a sample is taken and that not all sample units are observed... It is also assumed that auxiliary information is available for all units in the population. ...

#### A model-based approach to estimation of finite population total using local linear polynomial regression estimator

(2012-02-01)

Estimation of finite population totals in the presence of auxiliary information is considered. A class of estimators based on local polynomial regression is proposed. Like generalized regression estimators, these estimators ...

#### Laminar natural convection in a rectangular cavity

(2012-02-01)

This project is basically a numerical study of the structure of the flow and heat transfer rates due to collision of opposed laminar natural convection boundary layer in an enclosure.
Natural convection plays an important ...

#### The effects of streaming on mathematics achievement among secondary school pupils in Kisumu, Kenya

(2012-02-02)

This study investigated the effects of streaming on Mathematics achievement. The study examined whether the Learning setting played a significant role in determining pupil achievement and whether the effect of the Learning ...

#### An interaction model between Cotesia flavipes and Cotesia sesamiae, parasitoids of the gramineous stem-borers at the Kenya Coast

(2012-02-01)

One of the greatest challenges facing the people of sub-Saharan Africa is the production of sufficient food to feed a rapidly increasing population in the face of dwindling finances. As the population grows at 3% and food ...

#### Solving equilibrium equations for stress and deflection functions in a thin elastic shallow shell

(2012-02-02)

A problem connected with the study of thin elastic shallow shells in the theory of non-linear elasticity is considered. The equilibrium equations are in the form
V4 B1 (x, y) + Eh n4 B2 (x,y)=0
DV 4 B2 (x,y) - n 4 B1 ...

#### Analysis of flow in regular bend pipe

(2012-02-01)

A fluid is a substance that deforms continuously on application of slight shear stress. The study of fluid mechanics deals with motion of fluids and conditions that support or after motion.
Fluid mechanics can be divided ...
