An assessment of the age reporting in Tanzania population census
Mwambene, Eric; Appunni, Sathiya Susuman; Hamisi, Hamisi F.; Lougue, Siaka; Regassa, Nigatu; Ogujiuba, Kanayo (Academic Research Publishing, 2012)The objective of this paper is to provide data users with a worldwide assessment of the age reporting in the Tanzania Population Census 2012 data. Many demographic and socio-economic data are age-sex attributed. However, ... -
Automorphism groups of graph covers and uniform subset graphs
Mumba, Nephtale; Mwambene, Eric (Taylor and Francis Group, 2018)Hofmeister considered the automorphism groups of antipodal graphs through the exploration of graph covers. In this note weextend the exploration of automorphism groups of distance preserving graph covers. We apply the ... -
Binary codes and partial permutation decoding sets from the odd graphs
Fish, Washiela; Fray, Roland; Mwambene, Eric (Walter de Gruyter, 2014)For k ≥ 1, the odd graph denoted by O(k), is the graph with the vertex-set Ω{k} , the set of all k-subsets of Ω = {1, 2, . . . , 2k + 1}, and any two of its vertices u and v constitute an edge [u, v] if and only if u ∩ ... -
Codes from adjacency matrices of uniform subset graphs
Fish, W.; Key, J. D.; Mwambene, Eric (Springer, 2017)Studies of the p-ary codes from the adjacency matrices of uniform subset graphs Γ(n,k,r)Γ(n,k,r) and their reflexive associates have shown that a particular family of codes defined on the subsets are intimately related ... -
Self-similarity of human protein interaction networks: a novel strategy of distinguishing proteins
Fadhal, Emad; Gamieldien, Junaid; Mwambene, Eric (2015)The successful determination of reliable protein interaction networks (PINs) in several species in the post-genomic era has hitherto facilitated the quest to understanding systems and structural properties of such networks. ... -
Some meta-cayley graphs on dihedral groups
Allie, Imran; Mwambene, Eric (Springer, 2019)In this paper, we define meta-Cayley graphs on dihedral groups. We fully determine the automorphism groups of the constructed graphs in question. Further, we prove that some of the graphs that we have constructed do not ...
