1. Sites in languages other than English should be submitted to appropriate
World category as listed under the heading "This category in other languages."
2. This category is intended to service aerospace technical professionals and academia. Any non-commercial or commercial sites that deal with aerospace technologies and that are of general use to this community of professionals are acceptable. 3. This category differs from the Science/Technology/Space category in that the latter will also include many sites of interest to amateur space enthusiasts and lay people. This category and the space category may duplicate some listings for the major resources (such as NASA), but the goal is to minimize this duplication and cross-reference where possible. 4. Sites relating to the natural world beyond the earth, and the instruments used to study it, should be submitted to Science/Astronomy. 5. Sites relating to the study of weather and atmospheric phenomena should be submitted to either Science/Earth_Sciences/Meteorology or Science/Earth_Sciences/Atmospheric_Physics. |
This category covers the arts, sciences, and technology of aeronautics and astronautics.
|
Note: Category may become /Science/Technology/Biomedical Engineering/Products & Services in the future. For this reason submissions of both products and services will be considered (not just laboratory equipment). |
This site is devoted to Biomedical Engineering, either in the electrical and mechanical engineering field. Submit your site too!!!
|
The category has a number of specific sub categories. Please take the time to review these and ensure your submission is placed in the category most suited to your site . Suppliers of products or services should submit their sites to an appropriate category in our Business section. Specific links to which can usually be found as an @linked sub category of this main category, or in the list of related categories. |
This category is where information related to the science and practice of civil engineering goes.All businesses that provide civil engineering services as their primary goal go into Business/Industries/Engineering/Civil. Products and services of interest to the civil engineering community will be listed in the interim in Products and Services, but will be moved to a Business category soon.
Computational Engineering is high performance computing for engineering analysis and simulation. It typically involves parallel and vector capabilities and networking systems. New algorithms and analytic techniques are also used to enhance the power of these computational tools.
|
Please submit only sites which have some lasting value, such as proceedings, slides, reports or photographs. |
Conferences, meetings and workshops are an important part of the technological enterprise.Most conferences fit in a category for conferences in a specific area of technology. These categories are listed as links from the Science:Technology:Conferences category, which also lists sites for broad-spectrum scientific meetings and for organizations that conduct meetings in a wide range of fields.
| Please submit sites here which concern companies which offer the service of immersing metals and other materials in liquid nitrogen in order to increase their wear, or similar "dry" techniques which use liquid nitrogen temperatures without actual immersion. Also submit sites here for companies which manufacture such systems. |
This category includes all aspects of Cryogenics: the production and study of extreme sub-zero temperatures. This includes the production, use, and storage of liquid gases (nitrogen, oxygen, helium), mechanical freezers for those temperatures, and the attempts to reach absolute zero. It also includes a recent use of cryogenic technology in which metals are dipped in liquid nitrogen to improve various qualities.
|
Please submit only resources that are at least partly in English. Sites in other languages should be added to the appropriate category under /world. |
Cybernetics, the theory of intercausal networks underlaying communication and organization processes in dynamical systems, forms a metatheoretical superstructure for individual subdisciplines as systems theory, communication theory, connectionism or decision analysis. Yet, applied cybernetics serves as auxiliary science for practical fields as biology, psychology, medicine and technology. Complemenatary to this sectoral segmentation cybernetics can be classified into several layers. The inner layer is formed by general theoretical cybernetics (K1) that finds its concretization in the investigation of the realities (K2). Among the K2 the above mentioned subdisciplines (as general systems theory, control theory, information theory or game theory) are to be counted. Practical applications of cybernetics (biological cybernetics, control systems technology, computer science etc.) fall into the external layer (K3). Founded by von Foerster 'Second-order cybernetics' denotes a progressive intellectual movement within cybernetics and systems thinking that reached fruition in the 1970's. The most common explanation for the movement's agenda is that it turned the principles of cybernetics upon cybernetics itself. In second-order cybernetics, the observer of a system must be described and explained as well as the system observed. Practicability and consistent links to microtheories of the applied sciences are critical for the K3's success.

Failure to submit to the most specific appropriate category can delay the consideration of your submission. For more information, please refer to the DMOZ Science FAQ. |
In general, the concept of energy refers to the potential for causing changes. In physics, energy is the ability to do work and has many different forms (potential, kinetic, electromagnetic, etc.) No matter what its form, physical energy has the same units as work; a force applied through a distance. The SI unit of energy, the joule, equals one newton applied through one meter.
Topics for this category include energy resources, energy utilization technologies, technology research and technical innovations, and analytical aspects of energy policy.
The top of this category holds sites from companies or agencies that claim expertise in many engineering subjects, or consulting firms that claim expertise in a broad set of engineering or technology disciplines.04/01/00
