This paper is a continuation of work originally undertaken by the authors which predicts the static pose of a 1:20 scale dragline bucket and rigging throughout its workspace. Based on the results of this prior work, a two degree of freedom pendulum model is used to describe the dynamic response of the bucket to a small velocity inputs of the drag-rope. Linear differential equations, valid for s...

Using basic terms, BBD chips create a analog representation of the signal by storing an electrical charge that is passed along the “bucket brigade”. The charge is passed at a rate determined by the clock and the magnitude of charge stored at any given instant is an analog value, unlike a digital delay where the amplitude is assigned to a digital value that has discrete steps. At first glance, t...

We introduce the concept of local bucket error for the mini-bucket heuristics and show how it can be used to improve the power of AND/OR search for combinatorial optimization tasks in graphical models (e.g. MAP/MPE or weighted CSPs). The local bucket error illuminates how the heuristic errors are distributed in the search space, guided by the minibucket heuristic. We present and analyze methods...

Bucket sort and RADIX sort are two well-known integer sorting algorithms. This paper measures empirically what is the time usage and memory consumption for different kinds of input sequences. The algorithms are compared both from a theoretical standpoint but also on how well they do in six different use cases using randomized sequences of numbers. The measurements provide data on how good they ...

The dynamics and throughput of a bucket brigade production system is studied when workers speeds increase due to learning. It is shown that, if the rules of the bucket brigade system allow a re-ordering of its workers then the bucket brigade production system is very robust and will typically rebalance to a self-organizing optimal production arrangement. As workers learn only those parts of the...

The paper describes a new generic branch and bound scheme that uses heuristics generated mechanically by the mini-bucket approximation. The scheme is presented and evaluated for the Most Probable Explanation (MPE) task in Bayesian networks. We show that the mini-bucket scheme yields monotonic heuristics of varying strengths which cause different amounts of pruning during search. The resulting B...

This survey paper shows different mechanisms for controlling congestion in ATM network and some suggested solution for the existing mechanism to be modified using fuzzy logic. Different mechanisms are Jump Window (JW), Exponentially Weighted Moving Average (EWMA), and traditional Leaky Bucket (LB) and Fuzzy Leaky Bucket Algorithm. The Fuzzy Leaky Bucket (FLB) modifies the token rate according t...

The interesting fact emerges that farm workers, not properly instructed in the cleansing of covered pails, were actually getting worse results with them than with open pails :? Buckets, open and covered, were washed by the farm hands with warm water and a cloth in accordance with the usual practice. The milk taken into the covered bucket contained many more bacteria than that taken into the ope...

In this work we provide a combinatorial analysis of bucket recursive trees, which have been introduced previously as a natural generalization of the growth model of recursive trees. Our analysis is based on the description of bucket recursive trees as a special instance of so called bucket increasing trees, which is a family of combinatorial objects introduced in this paper. Using this combinat...
