To assist Java programming educations, we have developed a Web-based Java Programming Learning Assistant System (JPLAS). JPLAS provides fill-in-blank problems for novice students to learn Java by filling blank elements composed of reserved words, identifiers, and control symbols. In this paper, we propose a graph-based blank element selection algorithm to select as many blanks as possible such ...

In the last number of The Psychological Clinic I explained the purpose of the blank, the general arrangement of the items, and the method of grading employed, especially the method of grading mentality. To assist me in the further presentation of the items of this blank, I have reproduced an actual blank partially filled out, which will be found on the next page. At the top of the blank is the ...

Einen Problembereich im Verkehrssektor stellen Tourenplanungsprobleme dar. Diese entstehen, wenn Personen oder Güter von einem Transportmittel zu verschiedenen Orten gebracht und/oder abgeholt werden müssen. Im Allgemeinen geht es darum Aufträge zu erfüllen und die Anzahl der nötigen Touren sowie die Gesamtstrecke zu minimieren (Christofides et al. (1979)). Ziel dieser Arbeit ist es ausgewählte...

Heutige Business Intelligence (BI)-Lösungen sind nur unzureichend in der Lage, Managern Entscheidungshilfen an die Hand zu geben, die auf der Analyse innerbetrieblicher Kommunikationsprozesse basieren. Diese Studie schildert den ersten Einsatz einer BI-Anwendung, die Daten über die Kommunikation der Mitarbeiter innerhalb eines Unternehmens erhebt und analysiert (unter anderem via Bluetooth und ...

The current study investigated the role of the inter-screen luminance contrast (ISLC) of trial blank screens between target and mask screens in visually masking scenes. Participants performed a scene gist recognition task in which we varied mask strength, blank screen luminance, and stimulus onset asynchrony (SOA). Results showed that the more luminant white, and less luminant black, blank scre...

This study describes a new simple, sensitive and selective catalytic kinetic spectrophotometricmethod for the determination of vanadium (V). The method is based upon the catalytic effect ofvanadium (V) on the oxidation of Carminic acid by bromate in sulfuric acid media. The reaction wasfollowed spectrophotometrically by measuring the decrease in absorbance at 490 nm and thedependence of sensiti...

The effect of aqueous solution of citric acid (CA) on the lipid stability of the European catfish (Silurus glanis) fillets during frozen storage (up to 6 months) was investigated. Rancidity development was measured by several biochemical indices (free fatty acids, peroxides and TBA) and complemented by the measurement of expressible moisture and sensory evaluation (flesh odor, consistency and f...
