This paper describes a manipulation primitive called toppling—knocking a part over. We derive the mechanical conditions for toppling and describe two applications to conveyor-based parts feeding. Toppling complements previous approaches to conveyor-plane feeding, allowing full three-dimensional parts feeding on a constant-speed conveyor.

This paper presents the study of strengthening R/C beams with large circular and square opening located at flexure zone by Carbon Fiber Reinforced Polymer (CFRP) laminates. A total of five beams were tested to failure under four point loading to investigate the structural behavior including crack patterns, failure mode, ultimate load and load deflection behaviour. Test results show that large o...

We consider a sensorless approach to feeding parts on a conveyor belt using pins (rigid barriers) to topple parts into desired orientations. Given the n-sided 2D convex projection of an extruded polygonal part, its center of mass (COM), and coefficients of friction, we develop an O(n) algorithm to compute the toppling graph, a new data structure that represents the mechanics of toppling includi...

Why are n-player games much more complex than two-player games? Is it much more difficult to cooperate or to compete? n-player Toppling Dominoes is an n-player version of Toppling Dominoes, a two-player combinatorial game. Because of queer games, i.e., games where no player has a winning strategy, cooperation is a key-factor in nplayer games and, as a consequence, n-player Toppling Dominoes pla...

The objective measurement of blocking artifacts plays an important role in the design, optimization, and assessment of image and video coding systems. We propose a new approach that can blindly measure blocking artifacts in images without reference to the originals. The key idea is to model the blocky image as a non-blocky image interfered with a pure blocky signal. The task of the blocking eff...

In this study the influence of tubule orientation on the strength of human dentin under static and cyclic loads was examined. Rectangular beams were sectioned from the coronal dentin of virgin extracted molars (N=83) and then loaded in quasi-static 4-point flexure or 4-point flexural fatigue to failure. The flexure strength, energy to fracture and fatigue strength were evaluated for specimens w...

This paper presents some simple ideas about domino gates. Domino gates are implementations of logical operations using toppling dominoes to represent the movement of information (bits). The actively toppling domino represents a logic one, and absence of toppling represents logic zero. The domino model can be used as a representation of single-shot wave gates in unconstrained media, such as sub-...

Abstract The contributions of the current analytical models on prediction stability slope subjected to slide head toppling failure mechanisms, have always focused idealized geometry comprising regular blocks dipping into face. Besides, influence groundwater and stabilizations from lowermost block been overlooked in available literature. In this article, solutions that incorporates kinematic mec...
