The expressiveness of the C/C++ preprocessing facility enables the development of highly configurable source code. However, the usage of language constructs like macros also bears the potential of resulting in highly incomprehensible and unmaintainable code, which is due to the flexibility and the “cryptic” nature of the preprocessor language. This could be overcome if suitable analysis tools w...

The concept of Genealogical Sorting Indexes (GSIs) was first introduced by Cummings et al. [1]. Given a set of observations belonging to different groups (represented in the form of a hierarchial tree), the Genealogical Sorting Index (GSI) value obtained for a particular group provides a quantitative measure of how closely the observations belonging to this group have clustered in the given tre...

A new time-domain decomposition for weakly stationary or trend processes is introduced. The method based on trigonometric polynomial modeling, and it explicitly devised to disentangle medium long-term short-term fluctuations in macroeconomic financial series. multivariate extension involving sequential univariate decompositions Principal Components Analysis also provided. Based this approach, c...

Data warehouses are used to store large amounts of data. This data is often used for On-Line Analytical Processing (OLAP). Short response times are essential for on-line decision support. Common approaches to reach this goal in read-mostly environments are the precomputation of materialized views and the use of index structures. In this paper, a framework is presented to evaluate different inde...
