About Document Knowledge Base

This is a collection of digital documents from various journals or web sites that I found useful or interesting. Several years ago I worked in a university Engineering library and had access to thousands of current journals, which got me started on this collection, consisting mostly of technical or scientific content.

Some of them may appear 'dated', but I think that certain pieces of knowledge are timeless.

Months are indicated either by a 2-digit number or a 2-character abbreviation.

Having worked in a university library, I use 2 characters to represent a particular month:
