Aerodynamics

Beginner's Guide to Aerodynamics What is aerodynamics? The word comes from two Greek words: aerios, concerning the air, and dynamis, meaning powerful. Aerodynamics is the study of forces and the resulting motion of objects through the air. Judging from the story of Daedalus and Icarus, humans have been interested in aerodynamics and flying for thousands of years, although flying in a heavier-than-air machine has been possible only in the last hundred years.

Compressible Aerodynamics Calculator This calculator, written in Javascript by William Devenport at the Aerospace and Ocean Engineering Department, Virginia Tech, computes the standard relations for compressible flow of a perfect gas. The calculator is intended to provide a faster more convenient alternative to printed tables and charts (e.g. NACA Report 1135).

Aircraft Aerodynamics and Design Group On-Line Technical Reports and Publications: a research lab in Stanford University's Department of Aeronautics and Astronautics involved with research in applied aerodynamics and aircraft design. Our work ranges from the development of computational and experimental methods for aerodynamic analysis to studies of unconventional aircraft concepts and new architectures for multidisciplinary design optimization.

Aircraft Design: Synthesis and Analysis This is a pre-release development version of a system of programs and textbook material to be released shortly on CD. This material is based on course notes for the class AA241A and B, a graduate level course in aircraft design at Stanford University. The course involves individual aircraft design projects with problem sets and lectures devoted to various aspects of the design and analysis of a complete aerospace system. Students select a particular type of aircraft to be designed and, in two academic quarters, define the configuration using methods similar to those used in the aircraft industry for preliminary design work. Together with the vehicle definition and analysis, basic principles of applied aerodynamics, structures, controls, and system integration, applicable to many types of aerospace problems are discussed. The objective of the course is to present the fundamental elements of these topics, showing how they are applied in a practical design.

Helicopter Aerodynamics much of the material has been taken from U.S. Army Field Manual 1-51, and then modified as appropriate.

STOP ABUSING BERNOULLI! LEARN HOW WINGS REALLY WORK-- During most of the 20th century, much of the popular teaching of how wings work has been false. In part this has been deliberate. Many years ago, a most famous aerodynamicist, Dr. Theodore VonKarman, instructed his assistant: "When you are talking to technically illiterate people you must resort to the plausible falsehood instead of the difficult truth." (From Stories of a 20th Century Life by W.R. Sears). Site author wants to sell you his book, but the page really is interesting and informative.

GALLERY OF FLUID DYNAMICS One of the most attractive features of fluid mechanics is the beauty of the flows one encounters. Whether one is observing vortex streets, the potential flow around an airfoil or body, shock refraction or diffraction, or waves breaking on a beach the aesthetic appeal of fluid mechanics is impossible to deny.

eFluids is a specialty web portal designed to serve as a one-stop web information resource for anyone working in the areas of flow engineering, fluid mechanics research, education and directly related topics.  It is designed to become the first step on the path to solving problems in flow engineering and fluid mechanics research and development for the global fluid dynamics community  by providing engineers, industry professionals, researchers, educators, and students with a consolidated, intelligently selected and organized database linking all aspects of the fluid flow specialization.

Anthropology

John H. Bodley, An Anthropological Perspective From Cultural Anthropology: Tribes, States, and the Global System, 1994. John H. Bodley is Chair of the Department of Anthropology at Washington State University. In this excerpt from his textbook on cultural anthropology, Bodley discusses the history of anthropological conceptions of culture. Bodley's own definition, similar in many ways to the baseline definition offered here, is a good example of contemporary anthropological views about culture; that is, it is descriptive, inclusive, and relativistic.

Theory in Anthropology Sociocultural Anthropology has been through dramatic changes in the last 30 years. As part of their work in the Indiana University Anthropology Department's "Proseminar in Sociocultural Anthropology" students have compiled webpages covering subdisciplines within the field, important organizations and associations, changes in anthropological perspectives over time, and prominent theorists. All are valuable resources for beginning and advanced students in sociocultural anthropology.

Computational Intelligence - A Logical Approach. By David Poole, Alan Mackworth and Randy Goebel. 1998. Oxford University Press, New York. "Our theory is based on logic. Logic has been developed over the centuries as a formal (that is, precise not obtuse) way of representing assumptions about a world and the process of deriving the consequences of those assumptions. For simple agents in simple worlds we start with a highly restricted simple logic. Then as our agent/environment requires, we increase the logical power of the formalism. Since a computer is simply a symbol-manipulation engine, we can easily map our formal theories into computer programs that can control an agent or be used to reason about an agent. Everything we describe is implemented that way." From the Preface, which is available online.

Computer Theory

Matroid Theory. Matroids are an abstraction of several combinatorial objects, among them graphs and matrices. The word matroid was coined by Whitney in 1935 in his landmark paper "On the abstract properties of linear dependence". In defining a matroid Whitney tried to capture the fundamental properties of dependence that are common to graphs and matrices. Simple matroids, that is matroids without loops and parallel elements, are frequently called combinatorial geometries. Matroid theory provides a framework in which problems in combinatorial optimization, operations research and graph theory become simpler to understand.

Hacking

Nmap ("Network Mapper") is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) they are offering, what operating system (and OS version) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Nmap runs on most types of computers and both console and graphical versions are available. Nmap is free software, available with full source code under the terms of the GNU GPL.

Top 75 Security Tools Anyone in the security field would be well advised to go over the list and investigate tools they are unfamiliar with. The list is slightly biased toward "attack" tools rather than defensive ones.

Bugtraq -- Arguably the most important Internet security list. Vulnerabilities are often announced here first, so check frequently! Current month | Archived posts

Penetration Testing -- While this list is intended for "professionals", participants frequenly disclose techniques and strategies that would be useful to anyone with a practical interest in security and network auditing. Current month | Archived posts

Vulnerability Development -- A moderated list for discussing possible security issues. Sometimes offers interesting insights. Current month | Archived posts

Info Security News -- Carries news items (generally from mainstream sources) that relate to security. Current month | Archived posts | About list

VulnWatch -- A non-discussion, non-patch, all-vulnerability announcement list supported and run by a community of volunteer moderators distributed around the world. Current quarter | Archived posts | About list

VulnDiscuss -- This sister-list of VulnWatch allows for discussions about new vulnerabilities. Current month | Archived posts | About list

Security Basics -- A high-volume list which permits people to ask "stupid questions" without being derided as "n00bs". About list
