Qualitative constraint calculi are representation formalisms that allow for efficient reasoning about spatial and temporal information. Many of the calculi discussed in the field of Qualitative Spatial and Temporal Reasoning can be defined as combinations of other, simpler and more compact formalisms. On the other hand, existing calculi can be combined to a new formalism in which one can repres...

In this paper we define a complex adapted connection of type Bott on vertical bundle of a complex Finsler manifold. When this connection is flat we get a vertical vector valued cohomology. The notions are introduced by analogy with the real case for foliations. Finally, using the partial Bott connection we give a characterization of strongly Kähler-Finsler manifolds. 2000 Mathematics Subject Cl...

We propose a natural Fedosov type quantization of generalized Lagrange models and gravity theories with metrics lifted on tangent bundle, or extended to higher dimension, following some stated geometric/ physical conditions (for instance, nonholonomic and/or conformal transforms to some physically important metrics or mapping into a gauge model). Such generalized Lagrange transforms define cano...

The present study deals with the innovation and possibilities of improving design solution a frame connection for two selected types fasteners. All specimens were made glued laminated timber. Dowel-type mechanical fasteners, combination bolts dowels, full-threaded screws used connection. main goal this research was to replace typical (common dowel-type fasteners) more modern, faster, easier in ...

We examined 27 resin casts of foetal liver veins and found three types of connection between portal vein and portal sinus. The most frequent connection was endo-lateral (66.7%), when the end of the portal vein joins with the lateral wall of the portal sinus. The next type was latero-lateral (14.8%). In this type, the lateral walls of the portal sinus and the portal vein join together. The last ...

large panel precast structures are analyzed based on the connection rigidity. however, the connections undergo nonlinear and inelastic response, when subjected to seismic loads. thus, to study the actual behavior of structure, the connection nonlinearity should be implemented in the joints. in this paper, three conventional connection types are modeled based on the envelope of their cyclic resp...
