Controlling autonomous, humanoid robots in a dynamic, continuous, and real-time environment is a complex task. We have used an Extended Kalman Filter to track the position and velocity of the soccer ball in the RoboCup 3D soccer simulation scenario. The influence of reducing the error in the ball estimate on a high-level behavior is then demonstrated using the keep-away behavior. We have applie...

In the past decade, research in neurocomputing has been divided into two relatively well-deened tracks: one track dealing with cognition and the other with behavior. Cognition deals with organizing, classifying and recognizing sensory stimuli. Behavior is more dynamic, involving sequences of actions and changing interactions with an external environment. The mathematicaltechniques that apply to...

Well over $1 billion was spent on televised political advertising in the U.S. in 2004. Given the ubiquity of the 30 second spot, one might presume that ads must affect viewers’ vote choices. Somewhat surprisingly, though, scholars have yet to make much progress in confirming this claim. In this paper, we leverage a comprehensive dataset that tracks political ads in the nation’s top media market...

Railway structures are one of the most important structures in transportation. So the lack of precise study of their dynamic behavior leads to irreparable damages. The significant factors contributing to the accurate analysis of the dynamic behavior of railways are the type of load and foundation used in it. In this study, an Euler-Bernoulli beam subjected to a moving load on a finite depth fou...

The understanding of the dynamic behavior of distillation columns has received considerable attention because distillation is one of the most widely used unit operations in chemical process industries. This paper reports a dynamic simulation study of the possible distillation columns sequences of Dew pointing unit in the second phase of South Pars Gas Refinery. In this unit, three columns are u...

This paper compares different track model formulations for the simulation of dynamic vehicle–track interaction in switches and crossings (S&C, turnouts) a multi-body (MBS) environment. The investigations are an extension S&C Benchmark with addition finite element 60E1-760-1:15 turnout. constitutes common reference from which four derived: co-running, modal superposition, incorporated into MBS c...

High speed trains are an indispensable part of rapid transportation systems in many countries. As the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. Geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

Weaker sections of a railway track, such as the approach sections, are prone to differential settlement under action repeated train loads. The tracks degrade more quickly at critical section adjacent traditional rail bridge because progressive deterioration. Opting for an integral abutment instead is gaining importance due its improved performance in terms track stiffness and reduced settlement...

Although the notion of grounding in dialogue is widely acknowledged, the exact nature of the representations of common ground and its specific role in language processing are topics of ongoing debate. Proposals range from rich, explicit representations of common ground in the minds of speakers (Clark, 1996) to implicit representations, or even none at all (Pickering and Garrod, 2004). We argue ...

The ability to perform rolling contact fatigue (RCF) experiments in wheel–rail material is provided by a new small–scale test rig, manifesting the actual dynamic behaviour of the railway system. In this paper, a multi-body dynamics (MBD) model is proposed, simulating the vibration behaviour of the prescribed rig. The new testing facility is modelled using a three-dimensional model of the vehicl...
