In 1992 neurophysiologists [20] found a new type of cells in areas V1 and V2 of the monkey primary visual cortex, which they called grating cells. These cells respond vigorously to a grating pattern of appropriate orientation and periodicity. Three years later a computational model inspired by these findings was published [9]. The study of this paper is to create a grating cell operator that ha...

Recently, IBM announced Blink Ultra (BLU) as an in-memory enhancement for DB2 for Linux, Unix, and Windows. The technology implemented in BLU was tested in various stages until it founds its current form as DB2 feature. In this paper, we give a brief summary on the origins of BLU and the adoption process from the BLINK prototype over the IBM Smart Analytics Optimizer to BLU itself.

A repetitive sequence collection is one where portions of a base sequence of length n are repeated many times with small variations, forming a collection of total length N . Examples of such collections are version control data and genome sequences of individuals, where the differences can be expressed by lists of basic edit operations. Flexible and efficient data analysis on a such typically h...

ÐWe have developed a flexible software environment called ADVIZOR for visual information discovery. ADVIZOR complements existing assumptive-based analyses by providing a discovery-based approach. ADVIZOR consists of five parts: a rich set of flexible visual components, strategies for arranging the components for particular analyses, an in-memory data pool, data manipulation components, and cont...

Which investments in real-time capabilities and decision-support IT-infrastructures are appropriate? In view of the recent in-memory systems this poses an urgent question to companies in many industries. Despite ample research on the causal relationship between IS investments and business value, especially the value quantification remains a difficult challenge. This paper contributes a business...

Atomic broadcasts play a central role in serialisable in-memory transactions. Best performing ones block, when a node crashes, until a new view is installed. We augment a new protocol for uninterrupted progress in the interim period.
