This paper presents the systems and results for the Event Detection task of the TRECVid 2008 evaluation campaign. The kind of events addressed are single-actor, without requiring detailed tracking of body parts; rather the body as a whole is considered and the interaction between people is not addressed. The events thus considered are the OpposingFlow, PersonRuns and ElevatorNoEntry. For the fi...

product innovation success has very much to do with the development of models ormetaphors that are able to guide actors. one can observe two traditions in thisregard: rational and non-rational models. apparently in the former the model, suchas “development funnel”, is regarded as a mechanism and rigid applicable, picturinginnovation as an orderly, goal-oriented, value-neutral, and systematic pr...

we characterize the rational subsets of a finite group and discuss the relations to integral cayley graphs.

this article examines capacity of rational dialogues to achieve ethical universalism. in positive attitude, rational ability considered as most important reason for possibility of achievement to common social-political norms and rights. rational dialogue, by creating a suitable space for dialogue beyond the private interests and involvement of state power; searches consensus on foundation of so...

economists have heralded the formulation of the expected utility theorem as a universal method of choice under uncertainty. in their seminal paper, stigler and becker (stigler & becker, 1977) declared that “human behavior can be explained by a generalized calculus of utility-maximizing behavior” (p.76). the universality of the rational choice theory has been widely criticized by psychologists, ...

In this paper, we study a geometric G^2 Hermite interpolation by planar rational cubic Bézier curves. Two data points, two tangent vectors and two signed curvatures interpolated per each rational segment. We give the necessary and the sufficient intrinsic geometric conditions for two C^2 parametric curves to be connected with G2 continuity. Locally, the free parameters w...
