Many important combinatorial optimization problems can be expressed as constraint satisfaction problems with soft constraints. When problems are too difficult to be solved exactly, approximation methods become the best option. Mini-bucket Elimination (MBE) is a well known approximation method for combinatorial optimization problems. It has a control parameter z that allow us to trade time and s...

Traffic shaping in high speed networks, including VDSL networks, occurs when congestion builds up in the outgoing VDSL network. Shaping mechanisms want smooth traffic. We used a leaky bucket too achieve traffic shaping. But leaky buckets still have a lot of non-conforming frames. However, as one way to solving this problem, we purpose a double-leaky bucket as the traffic shaping mechanism that ...

The cost-reliability of five sampling methods (visual search, drop cloth, beat bucket, shake bucket, and sweep net) was determined for four groups of predatory arthropods on cotton plants in Texas. The beat bucket sample method was the most cost-reliable sampling method for Orius adults, and the beat bucket and drop cloth were the most cost-reliable methods for Orius nymphs. The drop cloth and ...

Optical burst switching(OBS) is considered as one of preferable network technologies for the next generation Internet. The Internet has two traffic classes, i.e. real-time bursts and reliable bursts. It is an important subject for OBS to achieve cooperated operation of real-time bursts and reliable bursts. In this paper, we proposes a new effective traffic control method named Separate TB+LB (T...

The traditional bucket foundation use vertical wall, which like a cup is buried upside down in seabed. A new bucket foundation with partial inclined wall has been proposed in this article. Based on limit equilibrium analysis of threedimensional stress state of foundation, the calculation method of the horizontal bearing capacity of the new bucket foundation has been deduced, which has been veri...

Nowadays, the use of solar energy is incredibly important to be increased since renewable and also does not cause pollution. To harness energy, a collector device needed convert into heat energy. This study aimed analyze transfer in flat plate which used as source thermal water heating process for bathing. A double-glazed was absorb then transferred it pipe. The pipe material copper has very hi...

This is a companion report to Bittau et al. [1]. We restate and prove security of the Stash Shuffle. 1 Description of the Stash Shuffle The Stash Shuffle considers input and output items in B sequential buckets, (each holding at mostD , ⌈N/B⌉ items, sized to fit in private memory). At a high level, the algorithm first chooses a random output bucket for each input item, and then randomly shuffle...

We analyse the average number of buckets in a Linear Bucket tree created by n points uniformly dispatched on an interval of length y. A new bucket is created when a point does not fall in an existing bucket. The bucket is the interval of length 2 centered on the point. We illustrate this concept by an interesting tale of how the moon’s surface took on its present form. Thanks to an explicit Lap...

A controller for a miniature wheel loader is developed to scoop rock piles autonomously. During a scooping task operation, the load of the bucket varies momentarily according to the phase of scooping. Before the insertion of the bucket into the rock pile, the load is just the bucket weight, but after the insertion the reaction force from the rock piles is applied to the bucket. The values of th...
