The characterization of flow through Pelton hydro turbines allows the optimization their operation and maximization energy performance. in injector free jet area (the from outlet surface to runner bucket inlet surface) is influenced by several parameters: geometry components (nozzle spear), opening, turbine head. parameters (velocity distribution, pressure spread) are reflected efficiency. rese...

I . Effects of feeding liquid milk-substitute to young calves either by nipple-pail or open-bucket o n the rumen by-pass and on the rate of passage were studied. z. Sixteen Holstein calves, aged I week initially, were used in three experiments in which calves were slaughtered after they were given liquids (milk-substituteand water) containingchromic oxide and SrCI, .6H,O as a tracer either by t...

| This paper investigated the problem of deriving token bucket parameters from the observed traac patterns of computer network ows in two cases. In the basic case, we identiied the set of token bucket parameters for any given ow so that all the packets in the ow will be delivered immediately without incurring any delay or loss. Then, we extended the basic case by adding a queue to the token buc...

We investigate a combinatorial two-player game, in which one player wants to keep the behavior of an underlying water-bucket system stable whereas the other player wants to cause overflows. This game is motivated by data management applications in wireless sensor networks. We construct optimal strategies and characterize optimal bucket sizes for many instances of this game.

Since MapReduce became an effective and popular programming framework for parallel data processing, key skew in intermediate data has become one of the important system performance bottlenecks. For solving the load imbalance of bucket containers in the shuffle process of the Spark computing framework, this paper proposes a splitting and combination algorithm for skew intermediate data blocks (S...

The paper explores the potential of look-ahead methods within the context of AND/OR search in graphical models using the Mini-Bucket heuristic for combinatorial optimization tasks (e.g., weighted CSPS or MAP inference). We study how these methods can be used to compensate for the approximation error of the initially generated Mini-Bucket heuristics, within the context of anytime Branch-And-Boun...

Known Oblivious RAM (ORAM) constructions achieve either optimal bandwidth blowup or optimal latency (as measured by online roundtrips), but not both. We are the first to demonstrate an ORAM scheme, called Bucket ORAM, which attains the best of both worlds. Bucket ORAM simultaneously achieves a single online roundtrip as well as constant overall bandwidth blowup.

One way to coördinate the efforts of workers along an assembly line that has fewer workers than work stations is to form a bucket brigade. Each worker in a bucket brigade simultaneously assembles a single item (an instance of the product) along the line. The worker carries the item from work station to work station until either he hands off his item to a downstream co-worker or he completes the...

BACKGROUND Unintentional drowning is the leading cause of death for children younger than 5 years old. A bucket is one of the most common water container in which children can drown. The objective of this work was to evaluate the base diameter of a bucket and the necessary force to shed it. METHODS This was an experimental study. We used six galvanized buckets of different diameters. Each sel...
