As with most computer science problems, representation of the data is the key to ecient and eective solutions. Piecewise linear representation has been used for the representation of the data. This representation has been used by various researchers to support clustering, classication, indexing and association rule mining of time series data. A variety of algorithms have been proposed to obtain...

‎for a set of non-negative integers~$l$‎, ‎the $l$-intersection number of a graph is the smallest number~$l$ for which there is an assignment of subsets $a_v subseteq {1,dots‎, ‎l}$ to vertices $v$‎, ‎such that every two vertices $u,v$ are adjacent if and only if $|a_u cap a_v|in l$‎. ‎the bipartite $l$-intersection number is defined similarly when the conditions are considered only for the ver...

The multi-homogenous homotopy continuation method can solve all isolated solutions of polynomial systems. Different variable partition yields different multi-homogenous Bézout number, which gives the upper bound of the number of isolated solutions. However, the computation of the multi-homogenous Bézout number is hard. In this paper, the permanent formulation of the multi-homogenous Bézout numb...

This paper asserts that the software engineering (SE) research literature describes open source software development (OSSD) as a homogenous phenomenon. Through a discourse analysis of the SE research literature on OSSD, it is argued that the view of OSSD as a homogenous phenomenon is not grounded in empirical evidence. Rather, it emerges from key assumptions held within the SE research discipli...

Optical inspection of a thick layer of granules for foreign particles does not directly reveal their true number and the more so if the layer is not homogenous. This raises questions such as “how do I know if the layer is homogenous?” and “what is the relation between the observable particles and the true number?” In this work a theory is proposed for granules with a minority of flat plates tha...
