Accumulators are used in lots of applications. So they are used as a pressure accumulator for quick energy supply to hold a constant pressure (equalization of leakage), for pulsation damping and as an element of suspension. We can differ between 3 types of accumulators: 1. Diaphragm Accumulator, 2. Piston Accumulator 3. Metal Bellow Accumulator. At applications with high requirements to permeat...

In this paper we explain the mechanical design of the robot herring that we have developed. The use of mechanical accumulators is a fundamental issue in the design of this robot. Two different types of mechanical accumulators are implemented and tested as a spine on the robot. We argue that using an Euler buckled spine, on a robot fish, will give more efficient robots and a naturally occurring ...

Lactate dehydrogenase (LDH) and malate dehydrogenase (MDH) electrophoretic tissue patterns of two different orders of Elasmobranchii: Carchariniformes (Galeus melanostomus and Prionace glauca) and Squaliformes (Etmopterus spinax and Scymnorinus licha) were studied. The number of loci expressed for these enzymes was the same of other elasmobranch species. Differences in tissue distribution were ...

Parallel reductions represent a common pattern for computing the aggregation of an associative and commutative operation, such as summation, across multiple pieces of data supplied by parallel tasks. In this paper, we introduce finish accumulators, a unified construct that supports predefined and user-defined deterministic reductions for dynamic async-finish task parallelism. Finish accumulator...

Nymphs of Stenoscepa sp. feed on leaves of the Ni hyperaccumulator Berkheya coddii at serpentine sites in Mpumalanga Province, South Africa. These sites contain Ni hyperaccumulators, Ni accumulators, and plants with Ni concentrations in the normal range. We conducted studies to: (i) determine the whole-body metal concentration of nymphs (including those starved to empty their guts); (ii) compar...

An integrated theory of context effects in memory retrieval is introduced. The theory, called Retrieval by ACcumulating Evidence in an Architecture (RACE/A), integrates ideas from accumulator models in the cognitive architecture ACT-R. This new theory explains how a particular retrieval from declarative memory is influenced by concurrent cognitive processes. RACE/A accounts for memory interfere...

We propose a systematic approach for generating linear implied constraints that link the values returned by several automata with accumulators after consuming the same input sequence. The method handles automata whose accumulators are increased by (or reset to) some non-negative integer value on each transition. We evaluate the impact of the generated linear invariants on conjunctions of two fa...

Mammalian carnivores may be important agents of prehistoric bone accumulations. Taphonomic analyses assemblages used for specific assignment usually include information on feeding, breeding, denning and even defecating ecology extant species. Here, we review literature the Hyaenidae, Felidae Canidae families carnivores, focusing ecological behavioural traits that are commonly as criteria to ass...
