The American Physical Society's Division of Computational Physics (DCOMP), founded in 1986, explores the use of computers in physics research and education as well as the role of physics in the development of computer technology. Its goals are to promote research and development in computational physics, enhance the prestige and professional standing of its members, encourage scholarly publication, and promote international cooperation in these activities.

During the past several years, computer modeling and numerical methods have matured as problem-solving tools in real-world electromagnetics applications. Consequently, the need for an applications forum, of sufficient scope to include all modeling techniques and commonly used codes, became readily apparent. There was further consensus that both a regular meeting (with published proceedings) and an additional publication were appropriate. To these ends, ACES was organized, in 1986. Now formally chartered and incorporated as a non-profit organization, ACES is an international, inter-disciplinary, professional society, with a wide range of activities and services. The interdisciplinary scope of ACES is pivotal to maintaining a "cross-pollination" between the high-frequency and low-frequency applications.

The Applied Computational Research Society is a nonprofit organization created to foster multilevel, interdisciplinary approaches to computational simulation in the advancement of science and high technology. ACRS aims to transcend traditional domains for a truer understanding of the complex and coupled behaviors present in nature.

The Association for Computational Linguistics is THE international scientific and professional society for people working on problems involving natural language and computation.

CSCSI/SCEIO exists as a special interest group of the Canadian Information Processing Society (CIPS) for the promotion of interest and activity in artifical Intelligence (AI).

Foundations of Computational Mathematics (FoCM) is a nonprofit organization that supports and promotes research on foundations of computational mathematics. It fosters interaction among mathematics, computer science and other areas of computational science through its conferences, workshops and publications.

Interface is a membership society of computational scientists, statisticians, mathematicians and individuals from related discipline areas interested in the interface between computing science and statistics. Interests include topics such as computational statistics, statistical software, exploratory data analysis, data mining, pattern recognition, scientific visualization and related fields.

The International Society for Computational Biology is a scholarly society dedicated to advancing the scientific understanding of living systems through computation. Our emphasis is on the role of computing and informatics in advancing molecular biology.

Computational methods, in many different forms, are now used very widely in all branches of engineering and the sciences; and this use will undoubtedly increase during the coming decades. We therefore believe that it is very timely to form ISCES with the mission of bringing together, and for fostering cross-fertilization of ideas between, educators, researchers, and practitioners from all fields of engineering (including aerospace, civil, mechanical,computer science, microelectronics, MEMS, materials science, engineering mechanics, and others), and the sciences (including physics, biology, chemistry, health sciences,biomedical sciences, and others) worldwide, who have a common interest in computational methods and models.

The International Society for Mathematical and Computational Aesthetics is concerned with any design object, whether it be the machine-sculpted surface of a car body, the Beethoven Hammerklavier sonata, the Feynman propagator in quantum electrodynamics, or re-usable software. We are concerned with advanced research in four directions: (1) how the design decision-flow is controlled by aesthetics; (2) what structural aspects of a design object are taken to be aesthetic; (3) how aesthetic value is computed by the designer and user; and (4) how aesthetics is integrated with function in the design object.

Computational economics explores the intersection of economics and computation. Included within computational economics are special interest groups focusing on computational approaches to agent based models, econometrics and statistics, finance, macro modeling, and dynamics, as well as on Internet economics, programming languages, and teaching of computational economics. Some of these areas are unique to Computational economics, while others extend traditional areas of economics to new areas through computational techniques.

Problems in applied mathematics and computational science arise in companies that manufacture aircraft, automobiles, engines, textiles, computers, communications systems, chemicals, drugs, and a host of other industrial and consumer products, and also in various service and consulting organizations. They also arise in many research initiatives of the federal government, such as those in global change, biotechnology, and advanced materials. SIAM fosters the development of the methodologies needed in these application areas.
