Artificial Intelligence

artificial intelligence , bibliography , journal , genetic algorithms , neural networks

Artificial Intelligence is a field of science that has several goals. The first, often called "weak" AI, is the effort to design and implement computer systems that can perform tasks requiring intelligence when performed by humans. AI in computer games, knowledge based systems and such are typical examples of this branch. The second, less tangible branch, often called "strong" AI, is the research that ultimatly aims to build artificial systems that display real intelligence. It does this by trying to understand or model the nature of human intelligence. Both branches are multidisciplinary, in that they have close relations with the fields of computer science, philosophy, medicine, psychology, biology and linguistics.

Chiropractic is a method of treatment used by Chiropractors.

Chiropractors believe that many health problems are due to misalignment or subluxation of the joints in the spine and that this leads to problems with the nervous or neurological system of the body resulting in symptoms, pain, disease and ill health. By adjusting the joints of the spine or other joints of the body they help restore normal function. They treat people who have had accidents or sports injuries and those whose conditions may have been brought on by stress, lack of exercise, poor posture or illness. There are a number of different chiropractic methods of treatment. Some chiropractors also offer massage, advice on nutrition, diet, lifestyle, exercise and ergonomic advice.

...Informatics is an emerging discipline that has been defined as the study, invention, and implementation of structures and algorithms to improve communication, understanding and management of medical information. The end objective of biomedical informatics is the coalescing of data, knowledge, and the tools necessary to apply that data and knowledge in the decision-making process, at the time and place that a decision needs to be made. The focus on the structures and algorithms necessary to manipulate the information separates Biomedical Informatics from other medical disciplines where information content is the focus." Aamir M.

Solid biomass comes in different forms including what comes directly from the “producers” (grass, trees, shrubs, crop husks, etc.) and that which comes as waste from the animals that consume the producers (droppings or dung from animals and waste from humans). Biofuel is any fuel that originates from biomass. The three classes of biomass used for combustion are solid (e.g. wood, dried plants and animal waste), liquid (e.g. ethanol, methanol and vegetable oil) and gaseous (e.g. bio-methane and hydrogen).
