June 4, 2013 U.S. Naval War College Commemoration of the Battle of Midway: "Gettysburg and Midway: Historical Parallels in Command" Prof. Robert Rubel, Dean, Center for Naval Warfare Studies Introduction by Rear Adm. John N. Christenson, president U.S. Naval War College The battles of Gettysburg and Midway each represented a major turning point in their respective wars. In each case a vaunted enemy commander leading a tactically and technically outstanding force was defeated by an underdog American force. The reasons for the Confederate and Japanese defeats are similar, which provide lessons in operational level leadership. This lecture will trace the parallels between the battles and examine how the same defects in planning and decision making on the part of Gen. Robert E. Lee and Adm. Isoroku Yamamoto produced similar results: strategic defeat. ***** Disclaimer: The views expressed are the speaker's own and may not necessarily reflect the views of the Naval War College, the Department of the Navy, the Department of Defense, or any other branch or agency of the U.S. Government.

This second module concerning Homeland Security in Israel focuses on the organizational and operational environments that frame Israeli counterterrorism strategies. Contrary to the United States, Israel has only a small number of agencies that are actively engaged in various aspects of counterterrorism intelligence-gathering, combat, and law enforcement. The primary agencies and organizations within Israel are the Israel Police, the Israel Security Agency (ISA), the Israel Defense Force (IDF), and the Institute for Intelligence and Special Duties. We are also provided with a summary of Israel's governmental organization, and a comparative analysis of the United States and Israeli systems of government and law enforcement.
From the CISR video library (http://www.cisr.us) Dr. Thomas A. Berson, Anagram Laboratories Sun Tzu in Cyberspace April 9, 1998 at the Naval Postgraduate School (http://www.nps.edu) ABSTRACT Sun Tzu's classic book of strategy, Artof War, dates from the 5th century B.C.E. That it is still in print, still provocative, and still in use in officer training colleges worldwide is testimony to its enduring value. To study and comment on Artof War is a long-standing tradition. In this talk we will explore the thesis that Art of War remains relevant in the information age, particularly to the enterprise we now call information warfare. After an introduction to the history of Art of War, and a brief look at Sun Tzu's Theorem (used in public-key cryptography), we will select several lessons from the Thirty-Six Marvelous Strategies tradition of commentary. We will rework each of these lessons with the goal of bringing Sun Tzu's strategy to bear on the business of achieving information dominance. About Dr. Thomas A. Berson Anagram Laboratories Palo Alto, CA Dr. Berson is presently a member of A Congressionally chartered committee to review C4I systems in the U.S.military. He is a past-president of the International Association for cryptologic Research (IACR), and is the chair-elect of the IEEE Computer Society's Technical Committee on Security and Privacy. He an editor of the Journal of Cryptology and has served as guest editor of the IEEE Transactions on Software Engineering. He has chaired IACR and IEEE conferences.

Ultra was the designation adopted by British military intelligence in June 1941 for wartime signals intelligence obtained by breaking high-level encrypted enemy radio and teleprinter communications at the Government Code and Cypher School at Bletchley Park. Ultra eventually became the standard designation among the western Allies for all such intelligence. The name arose because the intelligence thus obtained was considered more important than that designated by the highest British security classification then used and so was regarded as being Ultra secret. Several other cryptonyms had been used for such intelligence. British intelligence first designated it Boniface—presumably to imply that it was the result of human intelligence. The U.S. used the codename Magic for its decrypts from Japanese sources. Much of the German cipher traffic was encrypted on the Enigma machine. Used properly, the German military Enigma would have been virtually unbreakable; in practice, shortcomings in operation allowed it to be broken. The term "Ultra" has often been used almost synonymously with "Enigma decrypts". However, Ultra also encompassed decrypts of the German Lorenz SZ 40/42 machines that were used by the German High Command, and the Hagelin machine and other Italian and Japanese ciphers and codes such as PURPLE and JN-25.

In mathematics and abstract algebra, group theory studies the algebraic structures known as groups. The concept of a group is central to abstract algebra: other well-known algebraic structures, such as rings, fields, and vector spaces can all be seen as groups endowed with additional operations and axioms. Groups recur throughout mathematics, and the methods of group theory have influenced many parts of algebra. Linear algebraic groups and Lie groups are two branches of group theory that have experienced advances and have become subject areas in their own right. Various physical systems, such as crystals and the hydrogen atom, can be modelled by symmetry groups. Thus group theory and the closely related representation theory have many important applications in physics, chemistry, and materials science. Group theory is also central to public key cryptography.

A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing – hence "field-programmable". The FPGA configuration is generally specified using a hardware description language (HDL), similar to that used for an application-specific integrated circuit (ASIC) (circuit diagrams were previously used to specify the configuration, as they were for ASICs, but this is increasingly rare). Contemporary FPGAs have large resources of logic gates and RAM blocks to implement complex digital computations. As FPGA designs employ very fast I/Os and bidirectional data buses it becomes a challenge to verify correct timing of valid data within setup time and hold time. Floor planning enables resources allocation within FPGA to meet these time constraints. FPGAs can be used to implement any logical function that an ASIC could perform. The ability to update the functionality after shipping, partial re-configuration of a portion of the design and the low non-recurring engineering costs relative to an ASIC design (notwithstanding the generally higher unit cost), offer advantages for many applications.

The Johns Hopkins University (commonly referred to as Johns Hopkins, JHU, or simply Hopkins) is a private research university in Baltimore, Maryland. Founded in 1876, the university was named for its first benefactor, the American entrepreneur, abolitionist, and philanthropist Johns Hopkins. His $7 million bequest—of which half financed the establishment of The Johns Hopkins Hospital—was the largest philanthropic gift in the history of the United States at the time. Daniel Coit Gilman, who was inaugurated as the institution's first president on February 22, 1876, led the university to revolutionize higher education in the U.S. by integrating teaching and research. The first research university in the Western Hemisphere and one of the founding members of the American Association of Universities, Johns Hopkins has ranked among the world’s top universities throughout its history. The National Science Foundation has ranked the university #1 among U.S. academic institutions in total science, medical, and engineering research and development spending for 31 consecutive years. Johns Hopkins is also tied for #12 in the U.S. News and World Report undergraduate program rankings. This video is targeted to blind users.

Historians with an interest in gender and science have illuminated the scientific endeavors and accomplishments of women, the barriers they have faced, and the strategies implemented to have their work peer-reviewed and accepted in major scientific journals and other publications. The historical, critical and sociological study of these issues has become an academic discipline in its own right. The involvement of women in the field of medicine occurred in several early civilizations, and the study of natural philosophy in ancient Greece was open to women. Women contributed to the proto-science of alchemy in the first or second centuries AD. During the Middle Ages, convents were an important place of education for women, and some of these communities provided opportunities for women to contribute to scholarly research. While the eleventh century saw the emergence of the first universities, women were, for the most part, excluded from university education. The attitude to educating women in medical fields in Italy appears to have been more liberal than in other places. The first known woman to earn a university chair in a scientific field of studies, was eighteenth-century Italian scientist, Laura Bassi. Although gender roles were largely defined in the eighteenth century, women experienced great advances in science. During the nineteenth century, women were excluded from most formal scientific education, but they began to be admitted into learned societies during this period. In the later nineteenth century, the rise of the women's college provided jobs for women scientists and opportunities for education. Marie Curie, the first woman to receive a Nobel Prize in 1903 (physics), went on to become a double Nobel Prize recipient in 1911 (chemistry), both for her work on radiation. Forty women have been awarded the Nobel Prize between ...
