Melting heat transfer effect has received much attention in contemporary years because of its significant applications, such as liquid polymer extrusion, frozen ground thawing, permafrost melting, casting and welding processes as well as phase change material, hot extrusion, polymers, ceramics and others is pushed or drawn through a die of the desired cross-section to produce different types of objects.
It is now accepted that most of the fluids in industry and engineering are non-Newtonian in nature.

Applications of Self-Organizing Maps in Structural Health Monitoring Inka Buethe1, a, Peter Kraemer2,b and Claus-Peter Fritzen1,c 1 University of Siegen, Institute of Mechanics and Control Engineering-Mechatronics, Paul-Bonatz-Strasse 9-11, 57076 Siegen, Germany 2 Woelfel Beratende Ingenieure GmbH + Co.
Introduction Self-Organizing Maps have been used in many science areas: as a tool for organizing large amounts of data, as a tool of speech recognition differing between several groups of people, for process monitoring in engineering and natural science, and for classification of data in different fields like finance and social science.
Still the brittle ceramics, the sensor consists of, might be the weakest link in the chain of monitoring the structure.

Ion Irradiation Effects in some Electro-active and Engineering Polymers: Studies by Conventional and Novel Techniques Somik Banerjee1,2,a, M.
These polymers are also mechanically less stable than engineering polymers and have poor processibility.
Like other structural and engineering polymers, ion irradiation has drastic effects upon EAPs.
