The bottleneck of a data warehouse implementation is the ETL (extraction, transformation, and load) process, which carries out the initial population of the data warehouse and its further (usually periodical) updates. There is a number of software products supporting the OLAP analysis. However, the ETL process implementation is not repeatable in a significant way. This paper reports on a resear...

Imagine a simulated world where the characters you interact with are almost human – they converse with you in English, they understand the world they are in, can reason about what to do, and they exhibit emotions. Some of these characters may be your friends, while others will oppose you. Unlike current video games, being successful in this world won’t just be a matter of who is quickest on the...

BACKGROUND Large efforts have focused on screening for genes involved in the virulence and pathogenicity of Verticillium dahliae, a destructive fungal pathogen of numerous plant species that is difficult to control once the plant is infected. Although Agrobacterium tumefaciens-mediated transformation (ATMT) has been widely used for gene screening, a quick and easy method has been needed to faci...

• The assumption of independence of errors, i.e., error of an observation is not related to or depends upon that of another. This assumption is usually assured with the use of proper randomization procedure. However, if there is any systematic pattern in the arrangement of treatments from one replication to another, errors may be nonindependent. • The assumption of additive effects can be defin...

Cellular transformation is the first step in cancer development. Two features of cellular transformation are proliferation in reduced serum and loss of contact inhibition. Electronic Cell-Substrate Impedance Sensing (ECIS) measurements have been used to measure cellular proliferation, cytotoxicity, apoptosis, and attachment. We have used impedance measurements to distinguish normal cells from c...

The kinetics and mechanism of bainite transformation have been studied in Fe-Cr-Mo-V-Ti-C steel high speed dilatometry backed by thermodynamic analysis. The complete transformation of austenite, however, has not occurred at any reported temperature. Obtained results confirm the incomplete reaction phenomenon with the cessation of the bainite transformation well before the paraequilibrium is ach...

Model transformation can’t be directly tested using program techniques. Those have to be adapted to model characteristics. In this paper we focus on one test technique: mutation analysis. This technique aims to qualify a test data set by analyzing the execution results of intentionally faulty program versions. If the degree of qualification is not satisfactory, the test data set has to be impro...
