BS 644 specifies requirements for the design, construction and performance of fully finished and glazed factory-assembled timber windows of various types.
It applies to windows that have been treated with either opaque, non-opaque finishes, or that are designed to support an externally fixed covering of another material, and that have been factory-glazed. It does not apply to windows supplied as kits for site assembly.
BS 644 applies to windows fabricated into frames in a factory, to be installed vertically (±15°) into the external face of buildings, as single or multi-light units, in coupled assemblies when appropriate, of the following types:
a) Hinged: side-hung (open in or out), top-hung (open out), bottom hung (open in), tilt and turn or turn before tilt
b) Projecting: side-hung (open in or open out) and top-hung (open out)
c) Pivoted: horizontal and vertical (hung centrally or off-centre)
d) Sliding: horizontal and vertical
e) Side-hung and top-hung (open out) fully reversible
f) Fixed light
g) Direct glazed frames.
BS 644 should be used for assemblies in which any frame member is not longer than 3 m. It does not apply to curtain walls that span across horizontal structural members of floors but does apply to windows within a curtain walling system. It is also applicable to assemblies up to the factory gate.

BS EN ISO 18279:2003 details a classification of imperfections that can occur in brazing joints; guidance on quality levels; and suggested limits for imperfections. BS EN ISO 18279:2003 covers only imperfections that can occur in connection with brazing without the effect of any additional service loads. Only the type, shape and position of such imperfections are covered; no indication is given of the conditions of occurrence or causes.

Guidance on the application of brazing and the manufacture of brazed joints.
Abstract
This European Standard provides guidance on the application of brazing and the manufacture of brazed joints. This standard gives an introduction to brazing and a basis for the understanding and use of brazing in different applications.
This standard covers joint design and assembly, material aspects for both parent material and filler materials, brazing process and process variables, pre- and post-braze treatment and inspection.
History and related standards
This European Standard supersedes BS 1723-1:1986 and BS 1723-2:1986, which are withdrawn.

We've just finished our lesson in partial differential equation , and the prof. assigned a mission to hand for next week.
The task/document is about how are partial differential equations applied in civil engineering.
How and why do civil engineers use partial differential equations for?
Elasticity with Mathematica:
An Introduction to Continuum Mechanics and Linear Elasticity
Author: Andrei Constantinescu, Alexander Korsunsky | Size: 2.21 MB | Format:PDF | Publisher: Cambridge University Press | Year: October 8, 2007 | pages: 266 | ISBN: 0521842018, ISBN-13: 978-0521842013
This book is intended for researchers, engineers and students in solid mechanics, materials science and physics who are interested in using the power of modern computing to solve a wide variety of problems of both practical and fundamental significance in elasticity. Extensive use of Mathematica in the book makes available to the reader a range of recipes that can be readily adjusted to match particular tastes or requirements, to visualize solutions, and to carry out symbolic and numerical analysis and optimization.

Innovative and individual detailed solutions for a range of different types of buildings
Strategies and measures for cost-effective planning and building
This volume from the 'in Detail' series highlights projects that are otherwise always overshadowed by more spectacular and extravagant buildings in the trade press. These examples show how cost-effective planning and building can be achieved. "Cost-Effective Building" takes the entire planning and implementation process into consideration - from office organization through the design phase and coordination of the execution planning, right up to actual execution. The focus throughout is on the building's profitability. The wide range of possible measures and strategies for implementing cost-effective execution presented provide various ideas and stimuli for architects and planners.
* Housing, schools, industrial buildings - cost-effective planning for all types of buildings.
* Wood, steel, concrete and brickwork - different materials allow for individual solutions
* Competent planning help drawn from practice
