Melt flow in continuous casting tundishes is normal[y characterized by a combined model. The model is used to analyze the residence time disttibution of fluid in a tundish, In this model, the fluid volume in tundish is considered to be consisting of the plug flow, well-mixed flow, and dead volumes. Although this model was proposed over 20 years ago, most researchers have either used it incorrec...

The paper describes the development of CVFE a 1-D/2-D Control Volume Finite Elements model within the frame of the D e cision Support system for Inundation Risk Evaluation and Emergencies management (DESIREE) project. The CVFE approach addresses and solves the discretisation problem, by defining a double mesh: the first one is a triangular mesh of FEs over which the momentum equations can be lu...

The project management discipline is expanding within many engineering activities. This discipline can facilitate strivings toward successful accomplishment of an engineering project. Therefore, many academic institutes teach the “project management” program. This study presents a novel approach that educates engineering students to become successful project managers based on contextual learnin...

Ambivalence, the presence of positive and negative reactions toward an object, typically involves the subjective experience of conflict. We investigate the role that the perceived validity of each side of an ambivalent attitude plays in producing subjective ambivalence (SA). Consistent with the metacognitive model of attitudes, we demonstrated that SA is reduced when people doubt either the pos...

The functional perspective on attitudes suggests that individuals will be more persuaded by advertisements that match their individual needs or attitude functions. Although previous research provided correlational support for this functional approach, the current study aimed to provide a stronger, experimental test. A pilot study validated situational manipulations of the value-expressive and k...

For original paper see ibid., vol 27, p. 686-91, Aug. 1997. In the above paper, a novel algorithm for adaptively updating the parameters of a fuzzy controller was proposed. The purpose of this letter is to point out that this algorithm, and its use, are well known. The authors of the above paper acknowledge the previous use of similar concepts, however this letter draws attention to a particula...

MPEG-2 video communications over ATM networks is one of the most active research areas in the field of computer communications. In this paper, we introduce a set of control mechanisms at different levels of the protocol architecture to be used in MPEG-2-based video communications systems using ATM networks as their underlying transmission mechanism. We argue that in order to be able to create v...
