– We have calculated the electron density maps of the ripple phase of dimyristoylphosphatidylcholine (DMPC) and palmitoyl-oleoyl phosphatidylcholine (POPC) multibilayers at different temperatures and fixed relative humidity. Our analysis establishes, for the first time, the exist
Kope and Fairview Ripple Marks: Brown and Adams Counties, Ohio
The directional data of cross-laminae and ripple marks in the Kope and Fairview Formations in Brown and Adams Counties, Ohio, show no statistically significant difference in mean orientation. The prevailing paleocurrent direction was towards the northnorthwest. A significant diff
Large Aeolian Ripples: Extrapolations from Earth to Mars
Introduction: The shapes produced on terrestrial surfaces that are continually subject to aeolian processes range in size from tiny ripples to giant draa [1]. The physical mechanism of the formation of ripples, the smallest of aeolian bedforms, is intimately related to saltation
Torque Ripple Minimization of BLDC Motor by Kalman Filter
In classical control of brushless dc motors, flux distribution is assumed trapezoidal and fed current is controlled rectangular to obtain a desired constant torque. However, in reality this assumption may not be correct due to nonuniformity of magnetic materials and design trade-
Torque Ripple Minimization of Switched Reluctance Drive Using a Neuro-fuzzy Control Technique
Simple power electronic drive circuit and fault tolerance of converter are specific advantages of SRM drives, but excessive torque ripple has limited its application. This paper presents a novel method of controlling the motor currents to minimize the torque ripple, using a neuro
Mind Your Credit: Assessing the Health of the Ripple Credit Network
The Ripple credit network has emerged as a payment backbone with key advantages for financial institutions and the remittance industry. Its path-based IOweYou (IOU) settlements across different (crypto)currencies conceptually distinguishes the Ripple blockchain from cryptocurrenc
Relational Rippling: A General Approach
We propose a new version of rippling, called relational rippling. Rippling is a heuristic for guiding proof search, especially in the step cases of inductive proofs. Relational rippling is designed for representations in which value passing is by shared existential variables, as
Output Ripple Voltage for Buck Switching Regulator (Rev. A)
Switched-mode power supplies (SMPSs) are used to regulate voltage to a certain level. SMPSs have an inherent switching action, which causes the currents and voltages in the circuit to switch and fluctuate. The output voltage also has ripple on top of the regulated steady-state DC
Best-First Rippling
Rippling is a form of rewriting that guides search by only performing steps that reduce the syntactic differences between formulae. Termination is normally ensured by a measure that is decreases with each rewrite step. Because of this restriction, rippling will fail to prove theo
Ripple: Overview and Outlook
Ripple is a payment system and a digital currency which evolved completely independently of Bitcoin. Although Ripple holds the second highest market cap after Bitcoin, there are surprisingly no studies which analyze the provisions of Ripple. In this paper, we study the current de
