Past research on the Tower of Hanoi problem has provided clear evidence for the importance of goal-subgoal structures in problem solving. However, the nature of the traditional Tower of Hanoi problem makes it impossible to determine whether there is any special cost associated with storing or retrieving goals. A variation of the Tower of Hanoi problem is described that allows one to determine s...

I describe an architecture for linking perception and action in a robot. It consists of three “towers” of layered components. The “perception tower” contains rules that create increasingly abstract descriptions of the current environmental situation starting with the primitive predicates produced by the robot’s sensory apparatus. These descriptions are deposited in a “model tower” which is cont...

We present a new explicit tower of function fields (Fn)n≥0 over the finite field with ` = q3 elements, where the limit of the ratios (number of rational places of Fn)/(genus of Fn) is bigger or equal to 2(q2 − 1)/(q + 2). This tower contains as a subtower the tower which was introduced by Bezerra– Garcia–Stichtenoth (see [3]), and in the particular case q = 2 it coincides with the tower of van ...

Despite prior efforts to solve urban problems and build smart cities using large-scale information, researchers have yet develop tools for city administrators easily access a diverse mix of information. To address this limitation, article proposes an augmented reality visualization system, GeoACT, which can digital twin present information from both macro micro perspectives. GeoACT employs 3D v...

Beginning with a discussion of energy and exergy analysis definitions, the presented study provides a descriptive mathematical model for energy and exergy analysis for a co-current gas cooling tower. For this purpose using conservation laws of mass, energy and momentum, the variation of temperature and enthalpy of gas and liquid streams are predicted along the tower length and are used in order...

This experimental study demonstrates the efficiency of simple control strategies to damp a 3-stage tensegrity tower structure. The tower is mounted on a moving support which is excited with a limited bandwidth random signal (filtered white noise) by a shaker. Our goal is to minimize the transmissibility between base acceleration and top plate acceleration using piezoelectric displacement actuat...

This article is the second in a two-paper series presenting results from wind tunnel and computational fluid dynamics (CFD) simulations of flow and dispersion in an idealized model urban neighborhood. Pollutant dispersion results are presented and discussed for a model neighborhood that was characterized by regular city blocks of three-story row houses with a single 12-story tower located at th...
