small business and entrepreneurship play critical role in stimulating economic activity, creating jobs, alleviating poverty and uplift living standards in africa. it is widely accepted that the micro and small enterprise (mse) sectors have the potential to provide a livelihood for a considerably large number of poor rural and urban women in ethiopia. women account for the larger share of the in...

The surface area of early visual cortices varies several fold across healthy adult humans and is genetically heritable. But the functional consequences of this anatomical variability are still largely unexplored. Here we show that interindividual variability in human visual cortical surface area reflects a tradeoff between sensitivity to visual details and susceptibility to visual context. Spec...

The tensor representation has proven a successful tool as a mean to describe local multi-dimensional orientation. In this respect, the tensor representation is a map from the local orientation to a second order tensor. This paper investigates how variations of the orientation are mapped to variation of the tensor, thereby giving an explicit equivariance relation. The results may be used in orde...

In this paper, Coherence Enhancement Diffusion (CED) is boosted feeding external orientation using new robust orientation estimation. In CED, proper scale selection is very important as the gradient vector at that scale reflects the orientation of local ridge. For this purpose a new scheme is proposed in which pre calculated orientation, by using local and integration scales. From the experimen...

the present study was an attempt to assess religious orientation and life satisfaction as well as to find out relationship of religious orientation with life satisfaction among university students. university students were also compared on religious orientation and life satisfaction with respect to their gender. the data for the present study was obtained from university students [n=200 (males ...

We show that models for orientation map formation, which invoke convolution in the dynamic equation, are in fact invoking non-local reaction diffusion. In the early stages of development it is unlikely that non-local interactions take place. We present a non-linear reaction diffusion model based on near neighbour interaction for formation of orientation map. Besides capturing all the essential ...

By means of a special type of wavelet unitary transform we construct an orientation score from a grey-value image. This orientation score is a complex-valued function on the 2D Euclidean motion group SE(2) and gives us explicit information on the presence of local orientations in an image. As the transform between image and orientation score is unitary we can relate operators on images to opera...
