THE DIRTY DOZEN
The Dirty Dozen is a concept developed by Gordon Dupont, in 1993, whilst he was working for Transport Canada, and formed part of an elementary training programme for Human Performance in Maintenance. Transport Canada identified twelve factors that degrade people’s ability to perform effectively and safely, thus leading to maintenance errors. These twelve factors, known as the “dirty dozen”. It is important to know the Dirty Dozen, how to recognize their symptoms, and most importantly,
Image Processing
Introduction to Image Processing
Issues to learn:
– principle of operation of the CMOS matrix;
CMOS Matrix (Complementary Metal Oxide Semiconductor) sensor works on the same principle as the CCD. The light falls on a silicon crystal and forms the pixels, generating electrical charges in them. Each pixel has its own converter and its own ‘’address’’. This technology was created with the aim of producting integrates circuits. Its advantage is a relatively simple and cheap method of production.

Read MoreIntroduction
Air pollution has been a public health problem since the discovery of fire. In ancient times, people lit fires in their caves and huts and often polluted the air with noxious smoke. The Roman philosopher Seneca wrote about the “heavy air of Rome in 61 BC and in the eleventh century banned the burning of coal in London.
The origin of our modern problems of air pollution can be traced to eighteenth-century England and the birth of the industrial revolution. Industrialization began replacing
