Introduction Perspex is a type of amorphous polymer and has the following repeat unit : If the PMMA is heated ‚ the side group of the polymer will start to rotate. As the temperature gradually increase and reach a certain temperature ‚ the polymer would lose its stiffness and becomes elastic like a rubber. This temperature is also known as glass transition temperature ‚Tg. The Tg is always lower than melting point of the polymer. By heating and cooling the polymer‚ and observing the changes in their physical

Auto-Coding and Natural Language Processing Executive summary Without changes to current coding technology and processes‚ ICD-10 adoption will be very difficult for providers to absorb‚ due to the added complexity and coding overhead of ICD-10. Automated coding‚ based on NLP‚ can help reduce the coding burden. Richard Wolniewicz‚ PhD‚ Director‚ NLP Advanced Technology 3M Health Information Systems Natural Language Processing (NLP) promises to reduce costs and improve quality

Natural Language Processing Natural language processing (NLP) is a field of computer science‚ artificial intelligence‚ and linguistics concerned with the interactions between computers and human (natural) languages. As such‚ NLP is related to the area of human–computer interaction. Many challenges in NLP involve natural language understanding -- that is‚ enabling computers to derive meaning from human or natural language input. An automated online assistant providing customer

Page 88-90 stated that plastics are polymers and are chemically unreactive because they are held together by stable single bonds‚ which also results in their chemical stability. The stability of plastics makes them resilient to breakage making them good replacements for fragile items such as glass. Some plastics are weakened and dissolved by organic non-solvents so not all plastics can be used for the same purposes. Plastics are moulded to different shapes with some being flexible like plastic bags

was investigated. This is the origin of natural language processing (NLP). The idea of natural language processing is to design and build a computer system that will analyze ‚ understand and generate natural human-languages. Natural language communication with computers has long been a major goal of artificial intelligence‚ both for the information it can give about intelligence in general‚ and for practical utility. There are many applications of natural language processing developed over the years
