NR TWI 3T023 - How to Maintain a Transition Curve
March 1, 2005 - NR

Introduction This Track Work Instruction covers the maintenance of transitions on curves. A transition is the length of track joining two sections of track with differing radii. In their commonest form they join straights to curves - but they also join curves to...

NR TWI 3T010 - How to Set out a Curve
March 1, 2005 - NR

Introduction This Track Work Instruction covers how to set out a new, or redesigned, curve on site where there are no Enhanced Permissible Speeds (EPS). Curves with EPS are designed with higher speeds for specific types of trains and additional constraints are needed...

NR TWI 3T030 - How to Maintain a High Speed Curve
March 1, 2005 - NR

Introduction This Track Work Instruction gives particular guidance on the maintenance of curves on high line speeds, which do not use the system of absolute track geometry. Network Rail Company Specifications lay down the tolerances relating to line speeds and must be followed...

ISO 16415 - Non-structural timber grading requirements
August 1, 2012 - ISO

This International Standard delineates and illustrates broad grade categories that specify essential features typically found in those categories based on commonalities of numerous national standards and grading rules used for non-structural timber of non-coniferous and...

Handbook of Elliptic and Hyperelliptic Curve Cryptography
July 19, 2005 - CRC

The discrete logarithm problem based on elliptic and hyperelliptic curves has gained a lot of popularity as a cryptographic primitive. The main reason is that no subexponential algorithm for computing discrete logarithms on small genus curves is currently...

ASTM E561 - Standard Test Method for KR Curve Determination
June 15, 2020 - ASTM

This test method covers the determination of the resistance to fracture of metallic materials under Mode I loading at static rates using either of the following notched and precracked specimens: the middle-cracked tension M(T) specimen or the compact tension C(T) specimen. A KR curve...

Growth Curve Analysis and Visualization Using R
September 7, 2017 - CRC

An increasingly prominent statistical tool in the behavioral sciences, multilevel regression offers a statistical framework for analyzing longitudinal or time course data. It also provides a way to quantify and analyze individual differences, such as developmental and...

NR/L3/TRK/3530/A01 - Track Lubricants: Curve Lubricants
June 2, 2012 - NR

This specification covers the type testing of lubricant properties during product acceptance and routine control / monitoring of the lubricant following product acceptance. Purpose This product specification defines the minimum requirements for rail curve lubricants used by Network Rail to...

Effect of cut-out on lift-curve slope.
May 1, 1974 - ESDU

ESDU Aero W.01.01.04 presents curves of the ratio of the wing or tailplane lift-curve slope with cut-out to that without cut-out plotted against cut-out span as a fraction of wing or tailplane span for various values of cut-out chord as a fraction of wing or tailplane...

ASTM D509-20 - Standard Test Methods of Sampling and Grading Rosin
September 1, 2020 - ASTM International

1.1 These test methods cover procedures for sampling and determining the grade of rosin delivered in commercial bags, barrels, drums or in molten form. Although developed for rosin, these methods can also be used for the grading of modified rosins and rosin based resins. Note 1: All...

Lift-curve slope of wing-body combinations.
December 1, 1995 - ESDU

ESDU 91007 applies to missiles in which interference loads make a large contribution because of the small span-to-body-diameter ratio; an axisymmetric body with mid-wing is considered at low angles of attack (less than 2 degrees) in subsonic or supersonic flow. The method takes the...

ASTM E561-23 - Standard Test Method for K R Curve Determination
May 1, 2023 - ASTM International

5.1 The KR curve characterizes the resistance to fracture of materials during slow, stable crack extension and results from the growth of the plastic zone ahead of the crack as it extends from a fatigue precrack or sharp notch. It provides a record of the toughness development...

Installed tailplane lift-curve slope at subsonic speeds
August 1, 2015 - ESDU

ESDU 89029 provides a simple semi-empirical correlation of experimental data from the literature for installed tailplane efficiency for both fin- and body-mounted cases. Efficiency here is installed lift-curve slope normalised by the theoretical free-air value, in this case as...

IETF RFC 8422 - Elliptic Curve Cryptography (ECC) Cipher Suites for Transport Layer Security (TLS) Versions 1.2 and Earlier
August 1, 2018 - IETF

This document describes key exchange algorithms based on Elliptic Curve Cryptography (ECC) for the Transport Layer Security (TLS) protocol. In particular, it specifies the use of Ephemeral Elliptic Curve Diffie-Hellman (ECDHE) key agreement in a TLS handshake and the use...

ASTM E561-22 - Standard Test Method for K R Curve Determination
May 1, 2022 - ASTM International

5.1 The KR curve characterizes the resistance to fracture of materials during slow, stable crack extension and results from the growth of the plastic zone ahead of the crack as it extends from a fatigue precrack or sharp notch. It provides a record of the toughness development...

ASTM E561-08e1 - Standard Test Method for K-R Curve Determination
November 1, 2008 - ASTM International

The K-R curve characterizes the resistance to fracture of materials during slow, stable crack extension and results from the growth of the plastic zone ahead of the crack as it extends from a fatigue precrack or sharp notch. It provides a record of the toughness development as...

ASTM E561-10 - Standard Test Method for K-R Curve Determination
November 1, 2010 - ASTM International

The K-R curve characterizes the resistance to fracture of materials during slow, stable crack extension and results from the growth of the plastic zone ahead of the crack as it extends from a fatigue precrack or sharp notch. It provides a record of the toughness development as...
