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...

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...

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...

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...

ISO 19624 - Bamboo structures - Grading of bamboo culms - Basic principles and procedures
September 1, 2018 - ISO

This document specifies grading procedures for visually and mechanically sorting round, or pole, bamboo for structural applications using such fundamental elements. Visual sorting is based on observable characteristics of the piece(s). Mechanical sorting is based on...

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...

ISO 21022 - Test method for fibre-reinforced cementitious composites - Loaddeflection curve using circular plates
November 1, 2018 - ISO

This document specifies a test method for evaluating flexural performance of fibre-reinforced cementitious composites (FRCCs) using derived parameters. These parameters are derived from the load-deflection curve obtained by testing a circular specimen supported on...

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...

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...

Effect of twin fins on isolated tailplane lift-curve slope
July 1, 2014 - ESDU

ESDU 91009 provides a method that is based on determining the effective (increased) aspect ratio of the tailplane due to the end plate effect of the fins. ESDU 70011 is then used to estimate the lift-curve slope for that effective aspect ratio. Wind-tunnel data drawn from the...

Slope of aerofoil lift curve for subsonic two-dimensional flow.
September 1, 1997 - ESDU

ESDU 97020 gives a method for predicting the linear viscous lift-curve slope of symmetric and cambered aerofoils in subcritical compressible flow. The VGK program (see ESDU 96028 and 96029 in the Transonic Aerodynamics Series) was applied to a range of NACA aerofoils and also...

Slope of lift curve for two-dimensional flow.
August 1, 2007 - ESDU

ESDU AERO W.01.01.05 is retained in the Series because it is referred to and used in a number of ESDU documents in Aerodynamics. To obtain values of the slope of the lift coefficient curve with angle of attack on an aerofoil in incompressible (or compressible but subcritical)...

Timber grading and scanning
March 15, 2005 - BRE

Timber is an immensely useful but naturally variable material. Wood can contain features, such as knots and sloping grain, that may not be suitable for certain end uses. Dimensional defects and distortion can also affect the use of timber. To use timber reliably for structural purposes, it is...

ISO 13912 - Structural timber - Machine strength grading - Basic principles
November 1, 2017 - ISO

This document establishes the basic principles for rules and procedures governing the machine sorting of timber for use in structural applications. This applies to conventional bending type strength-grading machines as well as more recent machines that use other properties for...
