Most built-in self test (BIST) solutions require specialized test pattern generation hardware which may introduce significant area overhead and performance degradation. Recently, some authors proposed test pattern generation on chip by means of functional units also used in system mode like adders or multipliers. These schemes generate pseudo-random or pseudo-exhaustive patterns for serial or p...

The energy density of conventional hydraulic accumulators is significantly lower than competing energy domains. In this paper, a novel solution to improve the energy density of hydraulic energy storage, the flywheel-accumulator, is presented. The flywheelaccumulator integrates rotating kinetic and pneumatic energy storage, where the hydraulic fluid is used to change the mass moment of inertia o...

This article presents a preference accumulation model that can be used to implement a number of different multi-attribute heuristic choice rules, including the lexicographic rule, the majority of confirming dimensions (tallying) rule and the equal weights rule. The proposed model differs from existing accumulators in terms of attribute representation: Leakage and competition, typically applied ...

An experiment featuring waterhammer in viscoelastic pipes is presented in which the effects of pipe-wall viscoelasticity on waterhammer pressures are investigated. A large-scale pipeline apparatus made of polyvinyl chloride (PVC) at Deltares, Delft, The Netherlands, has been used to carry out waterhammer experiments. Tests have been conducted in a reservoir-pipeline-valve system consisting of a...

Free spans or suspended spans normally occur in subsea pipelines due to the irregularity of seabed and byscouring phenomena around the installed non-buried pipeline. The hydrodynamic around the pipeline canlead to a vibration of the pipeline.This kind of vibration may cause fatigue damage to the pipeline. In orderto study the hydrodynamic around the pipeline, calculating the natural frequency o...

Brookhaven is undertaking the design, construction and commissioning of the accumulator ring and the beam transport lines for the 1-GeV Spallation Neutron Source. The operating pressure of the accumulator ring vacuum system will be 10 Torr and is needed to minimize the beam-residual gas ionization. The vacuum requirement, the layout of the ring vacuum system, and the design of the vacuum chambe...

In this paper we aim at exploiting the properties of the Brownian Local Time to estimate the Counterparty Credit Risk for a specific class of financial derivatives, i.e. the so called Accumulator derivatives, within a Black and Scholes-type market. The comparison with the results obtained by made use of a standard Monte Carlo approach, clearly shows the superiority of our proposal, which runs i...

Indonesian Navy (TNI AL) is the main component for Maritime Security and Defence. Because of that, TNI AL needs Indonesian Warship (KRI) to covered Maritime area. The main requirement from KRI is fulfilled by demand. To pock of fuel demand from KRI at Naval Base, it needs a new pipeline of fuel distribution network system. The pipeline network system used for maximum lifetime must be protected ...
