We report observations made on a run of transcritical flows over an obstacle in narrow channel. Downstream from the obstacle, decelerate supercritical to subcritical, typically with undulation subcritical side (known hydrodynamics as undular hydraulic jump). In Analogue Gravity context, this transition corresponds white-hole horizon. Free-surface deformations are analyzed, mainly via two-point ...

In this paper, we provide a dynamic graph theoretical framework for flocking in presence of multiple obstacles. In particular, we give formal definitions of nets and flocks as spatially induced graphs. We provide models of nets and flocks and discuss the realization/embedding issues related to structural nets and flocks. This allows task representation and execution for a network of agents call...

In this paper, the transverse vibrations of rectangular plate with circular central hole have been investigated and the natural frequencies of the mentioned plate with point supported by Rayleigh-Ritz Method have been obtained. In this research, the effect of the hole is taken into account by subtracting the energies of the hole domain from the total energies of the whole plate. To determine th...

The flow and heat transfer characteristics of a film jet inclined to different supersonic situations with varying Mach number the main were numerically investigated. In situations, complicated waves are generated by obstacle jet. this work, extra pressure is exerted onto jet, causing better attachment wall. strengthening decreases mixing between cooling. We observed multi-interfacial layered st...

We investigate how the use of haptic feedback through electrical muscle stimulation (EMS) can improve collision-avoidance in a robot teleoperation scenario. Background: Collision-free requires extensive situation awareness by operator. This is difficult to achieve purely visually when obstacles exist outside robot’s field view. Therefore, from other sensory channels be beneficial. Method: compa...

The relaxed-core Hartree-Fock (RCHF) approach to the calculation of E-shell photoionization cross sections is analyzed and applied to I(-shell single-hole ionization in CO. A direct method based on the Schwinger variational principle and single-center-expansion techniques is used to generate the continuum orbitals associated with the motion of the photoelectron in the direct and exchange potent...

in this paper, we calculate electron and hole impactionization coefficients in in0.52al0.48as using a monte carlo modelwhich has two valleys and two bands for electrons and holesrespectively. also, we calculate multiplication factor for electronand hole initiated multiplication regimes and breakdown voltagein in0.52al0.48as pin avalanche photodiodes. to validate themodel, we compare our simulat...

GOLDMAN, SUSAN R., and VARNHAGEN, CONNIE K. Comprehension of Stories with No-Obstacle and Obstacle Endings. CHILD DEVELOPMENT, 1983, 54, 980-992. Comprehension of stories with and without obstacles to goal attainment was examined. 16 secondand fifth-grade students and 16 adults listened to and read single-episode stories in which (1) the protagonist met the episode goal (no-obstacle ending) and...
