One of the most widely cited models in time estimation is the “pacemaker-counter clock” which consists of a pacemaker generating pulses and an accumulator in which pulses are stored. The level reached in this accumulator at the end of an interval to be estimated sets the subjective elapsed time. Although this model is able to accurately describe temporal performance, it can nevertheless be cons...

The purpose of the work is to consider organization working process six-cylinder diesel engines with a power 116 and 156 kW exhaust gas recirculation. following systems components were used in experimental configurations engine: Common Rail BOSСH accumulator fuel injection system an pressure 140 MPa, equipped electro-hydraulic injectors seven-hole nozzle 500 mm3 hydraulic flow; direct MOTORPAL ...

Absorption of selenate and selenite by excised roots of Astragalus Crotalariae, a selenium accumulator, and of A. lentiginosus, a non-accumulator, was favored by CaCl(2) and a pH of 4.0. The uptake of selenate and possibly selenite, is metabolically linked. Roots of a number of Astragalus species were examined, and in all cases selenate entered the roots much faster than selenite. In these shor...

Mathematical psychology and systems neuroscience have converged on stochastic accumulator models to explain decision making. We examined saccade decisions in monkeys while neurophysiological recordings were made within their frontal eye field. Accumulator models were tested on how well they fit response probabilities and distributions of response times to make saccades. We connected these model...

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...

Hydraulic accumulators (HAs) have been used successfully in regenerative braking systems by companies such as Ford and Eaton Corp. to increase fuel efficiency of heavy vehicles by as much as 25-35%. However, the relatively low gravimetric and volumetric energy densities of conventional HAs prohibit their use in average-sized passenger vehicles. In an attempt to address this problem, an elastome...

A hydraulic catapult system is proposed to simulate the movement of missile in launch tube, which mainly consists a high-speed cylinder, an accumulator group, main valve, servo valve and cable pulley mechanism. The key technical difficulties are that how improve response speed big flux increase limited stroke. An ingenious controlled designed mechanism applied lever. working principle design me...

Generally, during the accelerating process of construction machinery large inertia hydraulic swing system, a lot kinetic energy is accumulated, and it will be eventually dissipated through relief valve orifice decelerating process, which results in serious waste overflow loss. In order to solve this problem, new dual source motor with non-uniform flow distribution proposed, can drive high-frequ...

It has recently been shown that accumulators can be used elfciently for test pattem generation as well as for test response compaction. In this paper we present a BIST scheme for accumulators where the accumulator is simultaneously used as a test pattern generator and a response compactor during its own testing. We also show that the proposed BlST scheme is especially suitable for accumulator, ...
