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This European Standard supersedes BS 1723-1:1986 and BS 1723-2:1986, which are withdrawn.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

The Code and Specification are written as legal documents so that they may be adopted by reference in general building codes. The Code covers the design and construction of masonry structures, with subjects covered ranging from quality assurance to the details and development of reinforcement. Compliance with the Specification is required by the Code to control materials, labor and construction. The Code Commentary comments on subjects covered by the Code, gives some of the considerations in developing the provisions, and explains provisions, in particular new or revised provisions, that may be unfamiliar to users of the Code. Commentary on the Specification provides similar information on subjects covered by the Specification.
This code covers the design and construction of masonry structures. It is written in such form that it may be adopted by reference in a legally adopted building code.
Among the subjects covered are: definitions; contract documents; quality assurance; materials; placement of embedded items; analysis and design; strength and serviceability; flexural and axial loads; shear; details and development of reinforcement; walls; columns; pilasters; beams and lintels; seismic design requirements; glass unit masonry; and veneers. An empirical design method applicable to buildings meeting specific location and construction criteria are also included.

PyroSim is a graphical user interface for the Fire Dynamics Simulator (FDS). It is used to create fire simulations that accurately predict smoke movement, temperature, and toxin concentrations during a fire.
Key Features
PyroSim 2011 is a graphical user interface for version 5 of FDS and Smokeview. Some of PyroSim's key features include: * Edit geometry using floor plan images, angled walls, and other powerful tools. * Integrated execution of FDS and Smokeview * Full support for 64-bit operating systems * Run multi-CPU simulations with a single click * Import existing FDS4 and FDS5 models. * Convert FDS4 input files to FDS5 * Import AutoCAD DXF models directly or as background images. For a list features and bug fixes new in PyroSim 2010, please read the release notes. Download the Feature Slideshow to learn more about PyroSim's capabilities. PyroSim is designed to run on MS Window operating systems. Apple users have reported success using PyroSim with both VMWare Fusion and Parallels.
Bigger Models with PyroSim 64-Bit Edition
As of PyroSim 2008.2, registered users can take advantage of 64-bit hardware using a 64-bit version of PyroSim. The key simulation components (PyroSim, MPI, FDS) of this version are provided as 64-bit software. This allows access to memory beyond the traditional 3 GB limit in Windows operating systems - making it possible to create fire models with many more cells than with a 32-bit system. The 64-bit version requires a 64-bit computer and operating system.
Verification and Validation
The developers of FDS at the National Institute of Standards and Technology (NIST) use the model verification techniques outlined in ASTME 1355 to ensure the accuracy of the numerical solutions given by FDS. Additional information can be found in Part III of the FDS Users Guide.
FDS was also the subject of a verification and validation study sponsored by the US Nuclear Regulatory Commission and the Electric Power Research Institute. This work compares 5 different simulators based on several fire scenarios.
