This paper examines the structure and form of the Alley spaces in Kampala Central BusinessDistrict, with purpose to examine their uses, and the potential for urban renewal. The study employed multiplemethodological approaches and procedures including document review, case study approaches and analysis anddeduction of empirical findings, and explanation building. The study findings reveal that a...

ABSTRACT A vibrant and commercially active center is often the result of interesting, diverse building styles and or built-forms, pedestrian density along with variety of quality public places where people feel comfortable, spending time and shopping items for domestic and commercial functions in cities like Addis Ababa. The scale and design of buildings, pedestrian density, and other phy...

Algorithms for exact string matching have substantial application in computational biology. Time-efficient data structures which support a variety of exact string matching queries, such as the suffix tree and the suffix array, have been applied to such problems. As sequence databases grow, more space-efficient approaches to exact matching are becoming more important. One such data structure, th...

We show that the space of fully-grown n-trees has the homotopy type of a bouquet of spheres of dimension n ? 3 and that the character of the representation of n+1 on its only non-trivial reduced homology group is (Ind n+1 n Lie n ?Lie n+1): Introduction We investigate a certain space T n called the space of fully-grown n-trees, and we prove that it has the homotopy type of a bouquet of spheres ...

The main subject of this chapter is an application of an extended version of the polygonal line algorithm to hand-written character skeletonization. Skeletonization is one of the important areas in image processing. It is most often, although not exclusively, used for images of hand-written or printed characters so we describe it here in this context. When we look at the image of a letter, we s...

For any connected complex reductive group G, finitely generated discrete ? and a normal subgroup ?˜ with quotient ?, we study the associated G??-character variety, space of admissible G??-representations ?. We relation between this variety ?-fixed points in usual G-character to ?˜. In process, give classification isomorphism classes semi-direct products G??, fixed G ?. case where are fundamenta...

In this paper we use the Morse theory of the Yang-Mills-Higgs functional on the singular space of Higgs bundles on Riemann surfaces to compute the equivariant cohomology of the space of semistable U(2, 1) and SU(2, 1) Higgs bundles with fixed Toledo invariant. In the non-coprime case this gives new results about the topology of the U(2, 1) and SU(2, 1) character varieties of surface groups. The...

In the human brain, beneath the symbolic-type reasoning modeled by traditional rule-based systems, there is another level of computation. It is impleented in a subsymbolic substrate, in which operations are carried out by local interaction of simple computing element, without any central guidance. This substrate is especially evident in perception although, due to the physical \implementation" ...
