Memories of Tribology and Italy

Railway Open System Tribology Railway Open System Tribology

Tribology in the railway system is of increasing interest in the new railway era due to the demand for higher speed and load capacity. Since railway vehicles operate in an open environment, their performance depends greatly on temperature, humidity and natural and artificial contaminants. Meanwhile, the “feedback” of railway vehicles to the surroundings, such as noise and airborne particles, is...

Liquid Crystals in Tribology

Two decades ago, the literature dealing with the possible applications of low molar mass liquid crystals, also called monomer liquid crystals (MLCs), only included about 50 references. Today, thousands of papers, conference reports, books or book chapters and patents refer to the study and applications of MLCs as lubricants and lubricant additives and efforts are made to develop new commercial ...

Tribology of Manufactured Optical Surfaces

Optical components of non-planar geometry require special machining to produce. Single point diamond turning is the manufacturing method of choice to produce these surfaces. Three main factors contribute to the quality of these surfaces. Machine accuracy has shown improvements with the increased use of air bearings. Tool wear and design are shown to be effected by the crystal orientation of the...

Modeling storage and retrieval of memories in the brain

We have proposed a neural network model that stores the incoming information after orthogonalizing it in the same manner as vectors are orthogonalized. The scheme enables the brain to compare a new informational system with those in the memory and store its similarities and differences with the old memories in an economical manner. This allows the brain to have an enormous capacity and yet the ...
