In this paper, we present a new OLAP Mining method for exploring interesting trend patterns. Our main goal is to mine the most (TOP-K) significant changes in Multidimensional Spaces (MDS) applying a gradientbased cubing strategy. The challenge is then finding maximum gradient regions, which maximises the task of detecting TOP-K gradient cells. Several heuristics are also introduced to prune MDS...

In the past, research on changes in relative importance among broad three sectors— agriculture, industry, and service—showed general patterns of a country’s structural transformation along with economic development. However, there has been devoid of empirical studies investigating in the structural change within the manufacturing sector, which often plays a role of the engine in economic growth...

a r t i c l e i n f o Recent trends in customer-oriented markets drive many researchers to develop sequential pattern mining algorithms to explore consumer behaviors. However, most of these studies concentrated on how to improve accuracy and efficiency of their methods, and seldom discussed how to detect sequential pattern changes between two time-periods. To help business managers understand t...

The trypsin digestion technique has revealed a preferential loss of endothelial cells (in conditions other than diabetes) and eventually a total acellularity of many retinal capillaries. The surprise is that this may occur toithout recognized functional abnormality or without appreciable histologic change in the rest of the retina. Perhaps the retina has a large reserve capacity normally or per...

Emerging classes of systems are more and more subject to changes in their requirements and environment assumptions. Such changes have a far-reaching impact across several artifacts. This paper argues that patterns of co-evolution (or change patterns) can be observed between “privileged” pairs of artifacts, like the requirements specification and the architectural design. The paper introduces ch...

Sunday afternoon 10 August 1628, the naval vessel Wmu embarked on its first trip. The ship had been constructed in Stockholm according to the King’s wishes, and the recommendations of one of the most renowned ship builders at that time. It was heavily decorated, with sculptures both in the bow and the stem. It was armed with sixty-four bronze cannon, at that time a heavy armament, and the ship ...

Patterns have been proved useful in many problem domains. In the domain of software evolution, only behaviour-preserving patterns (e.g. refactorings) have ever been proposed. This paper proposes to broaden the scope of change patterns by means of a reification of any evolution efforts into styles. We define an evolution style as a first-class entity which is specified once and can be applied ma...

Process model quality has been an area of considerable research efforts. In this context, the correctness-by-construction principle of change patterns provides promising perspectives. However, using change patterns for model creation imposes a more structured way of modeling. While the process of process modeling (PPM) based on change primitives has been investigated, little is known about this...
