Updating the qr factorization and the least squares problem

This reduces rounding issues and the need to use excessive numbers of decimal places.

There are some exceptions to this rule: for example, the Japanese often quote their currency as the base to other currencies.

Special topics inf the form of case studies will be discussed related to: Introduction to sustainability: humanity and environment, the evolution of environmental policy, climate and global change, climate processes: external and internal controls, modern climate change, climate projections, biosphere, soil and sustainability, biodiversity and ecosystem functions, physical resources: water, pollution, minerals, environmental and resource economics, modern environmental management, systems of waste management, sustainable energy systems, sustainable infrastructure, embodied energy, life cycle, sustainable materials and construction, problem solving and tools of sustainability Phase relations; Soil classification, index properties, grain-size distribution; Effective stress principle; Flow through porous media, Darcy’s law, permeability, different heads, 2-D Seepage and flow nets; Compaction characteristics; Compressibility and Consolidation characteristics, 1-D compression response, Terzaghi’s theory of consolidation, secondary consolidation; Settlement of foundations, immediate and time-dependent settlement, allowable settlement; Shear-strength of Soil, Mohr-coulomb failure criteria, direct shear and UC tests; in situ test – SPT, CPT; Earth-pressure theory, Coulomb and Rankine approaches; Bearing capacity, failure modes, generalized bearing capacity equation, net- and gross bearing capacity, allowable bearing pressure.

* * * How to restore justice: Create a folder named Justice. The first puzzle is now called the Fractal Word Search.

It is available on the Hunt website under its name In the Details.

The 2nd edition of my book on this subject was published by CRC Press (Chapman & Hall) in April 2002 (ISBN 1-58488-171-2). David Smith from the Medical College of Georgia, USA, has notified me of certain missing references. As I can no longer access my ozemail web site, I shall make the latest versions of my subsets software available here.

For subset selection using the L1-norm, that is minimizing the sum of absolute residuals, here is toms615.f90 which is a translation of TOMS algorithm 615 to make it ELF90 compatible.

It is very likely that we have missed several highly important works.
