Using Developable Land Units as an Indicator of Rate of Growth of an Urban Area
(13-08-13)
Developable Land Units (DLU) have been used in combination with remotely sensed data as an indicator for tracking the rate of urban growth. The variables used to model this indicator(DLU) are namely available vacant land, ...

Innovative Farmer Advisory Services Using ICT
(2009)
Over the past 10 years, there has been a remarkable progress in the use of ICT in African agriculture, especially in the area of farmers’ access to market information. Various projects have been developed that integrate ...
Concrete use for sustainable development
(2013-05)
Concrete is a primary construction material of the modern age with over 13 billion metric tons being used globally every year. It is a man-made material with a great impact on the economy and the environment. Its properties ...
Nutrition and infection in national development
(1976)
This paper was written at the request of the Editor of the
American journal "Science" for their special issue devoted to the world
food problem published in 1975. The important synergistic relationship
between malnutrition ...
The Challenges of Rural Electrification in Sub-Saharan Africa
(University of Nairobi, 09-06-05)
This paper presents challenges of rural electrification. The main technical challenge of rural electrification programme to the power engineer is therefore the designing of an electrical distribution system for a dispersed ...
A Wavelet Based Image Watermarking Scheme With A CDMA/Hadamard Embedding Technique
(University of Nairobi, 15-02-07)
A new blind digital image watermarking scheme that employs a Hadamard matrix to spread the CDMA watermark in selected DWT coefficients in a gray-level cover image is proposed. The coefficients are obtained from the 1- level ...
Digital Filter Design Using an Adaptive Modelling Approach
(University of Nairobi, 2006)
This chapter presents the design of a finite impulse response (FIR) filter using the Wiener approach and compares it with a least mean squares (LMS) design. The Wiener filter is synthesized by computing the optimum weights ...
An Image Watermarking Method Based On The Singular Value Decomposition And The Wavelet Transform
(University of Nairobi, 28-09-07)
A robust image watermarking scheme in which a binary image is embedded in the singular values of selected DWT blocks in the horizontal and vertical sub-bands of a 1-level decomposition of a gray-scale image is proposed. ...
A spectral Subtraction Method for Noise reduction in Speech Signals
(University of Nairobi, 27-09-96)
A noise suppression algorithm for enhancing speech signals corrupted by additive white Gaussian noise is presented in this paper. The algorithm is based on the subtraction of estimated noise spectrum from the noisy speech ...
