Hipel, K.W., Jamshidi, M.M., Tien, J.M., and White, C.C.
- Abstract
Several important application areas that will dominate systems, man, and cybernetic (SMC) efforts for at least the next decade, together with the methods that will require further research and development in order to appropriately address these application domains, are considered herein. More specifically, four broad and pervasive system domains are examined: service systems, infrastructure and transportation systems, environmental and energy systems, and defense and space systems. Given the nature of these four application domains, a number of new systems [i.e., holistic-oriented, including system-of-systems (SoS)], man (i.e., decision-oriented, including decision informatics), and cybernetic (i.e., adaptive-oriented, including real-time control) methods are identified and their further development are discussed. Clearly, the IEEE Society on Systems, Man, and Cybernetics has a great future; its systems, man, and cybernetic methods are relevant for addressing challenging problems arising in system domains that are becoming dominant in this 21st century. However, the methods must be refined and expanded to meet the changing needs of the 21st century; from a system to a system-of-systems vision, from a disciplinary to a multidisciplinary outlook, from a mass production to a mass customization focus, from a steady state to a real-time perspective, and from an optimal to an adaptive approach.

3. Immaterial Transfers with Material Consequences.
- Author
-
Trope, R.L.
- Abstract
The need for such regulations is clear, but many firms underestimate the challenges of complying with the defense trade controls embodied in the US International Traffic in Arms Regulations (ITAR). Companies hoping to enter into defense contracts must therefore redefine their basic approach to technical data because the ITARs require that they control the destinations of their communications. For example, the ITARs prohibit unlicensed communications of sensitive data to foreign destinations (another country or a foreign national) [ABSTRACT FROM PUBLISHER]

4. Lessons learned using software-assisted systems engineering on large satellite development contracts.

Cooper, P.A.
- Abstract
Over the years, the world's defense industries have become quite proficient at developing large, complex hardware and software systems. In recent years, the ubiquitous deployment of personal computers has changed the way we work. Additionally, took designed to facilitate systems engineering have recently matured enough to start having a major impact on many major systems development efforts. Finally, the government's faster-better-cheaper acquisition philosophy has started driving prime contractors to a concurrent engineering approach toward systems engineering. This confluence of experts is has had unexpected impacts on both the flexibility and rigor of requirements management processes. While the maturing requirements and design took hold great promise in maintaining requirements traceability throughout the design process, the widespread use of desktop computing systems has inadvertently lulled many experienced systems engineers into sloppy processes because it now appears to be a simple matter to make a requirements change in a softcopy of a requirements document. Without strong process and management support, requirements changes inevitably start being derived in a broad spectrum of incompatible took and formats. This author is currently participating in the design phase of a major classified government satellite development effort. As an integral member of an extremely experienced requirements management team (boasting over 150 years of combined experience in the defense industry), this author has had the opportunity to watch the team navigate straight into many of the systems engineering potholes created when talented engineers implement concurrent engineering using a variety of tools without a consistent process framework. This paper, therefore, specifically addresses process and implementation challenges that arose when establishing a software-assisted concurrent-engineering approach on a large satellite development contract.

5. Defense radar development in Australia: 1939 to the present.
- Author

Sinnott, D.H.
- Abstract
Defense radar research and development in Australia is today largely, but not exclusively, confined within Australia's Defense Science and Technology Organization, DSTO, and its R&D collaborators in universities. Radar has a long history in Australia, dating back to World War II links with British defense radar development, and radar R&D continues to be an important focus within DSTO. It is impossible, in the context of a brief conference paper, to give other than the broadest-brush picture of Australian radar development over a half-century or more. So the approach taken is necessarily highly selective and focuses specifically on several illustrative development projects, in an attempt to convey the flavor of national radar research priorities, the way they drive R&D and likely future directions. Despite the escalating requirement for a national skills base in defense radar and allied technologies, there are currently legitimate concerns about the robustness of this base. Recruitment of high-caliber researchers into the field of radar and management of radar research careers are issues currently presenting major challenges. A number of initiatives are in place linking DSTO with university research; a recent effort to enhance the stature and visibility of radar research in Australia is the establishment of the Centre of Expertise in Microwave Radar as a joint venture between DSTO and Adelaide University.

Pinnaduwage, L.A., Hai-Feng Ji, and Thundat, T.
- Abstract
An urgent need exists for the development of inexpensive, highly selective, and extremely sensitive sensors to help combat terrorism. If such sensors can be made miniature, they could be deployed in virtually any situation. Terrorists have a wide variety of potential agents and delivery means to choose from for chemical, biological, radiological, or explosive attacks. Detecting terrorist weapons has become a complex and expensive endeavor, because a multitude of sensor platforms is currently needed to detect the various types of threats. The ability to mass produce and cost effectively deploy a single type of sensor that can detect a wide range of threats is essential in winning the war on terrorism. Silicon-based microelectromechanical sensors (MEMS) represent an ideal sensor platform for combating terrorism because these miniature sensors are inexpensive and can be deployed almost anywhere. Recently, the high sensitivity of MEMS-based microcantilever sensors has been demonstrated in the detection of a variety of threats. Therefore, the critical requirements for a single, miniature sensor platform have been met and the realization of an integrated, widely deployable MEMS sensor could be near. [ABSTRACT FROM PUBLISHER]

- Author
-
Shriver-Lake, L.C. and Ligler, F.S.
- Abstract
The war against terrorism requires numerous sensor technologies for homeland security. For the detection of bioterrorist agents, 1) generic detectors that indicate something amiss, 2) biosensors for rapid screening and presumptive identification, and 3) identification systems for definitive confirmation are all required. The Array Biosensor addresses the second need. This biosensor can detect multiple agents simultaneously in less than 15 min, is automated, and can be used on site. This paper reports on the current version of the automated system and reviews data obtained in assays for bioterrorist agents. [ABSTRACT FROM PUBLISHER]

Pantazi, A., Papadopoulos, A., Varsamou, M., Papandreou, N., Savvopoulos, P., Antonakopoulos, T., and Makios, V.
- Abstract
Air defense systems protect land and maritime resources from air attack. Depending on the regional characteristics and type of conflicting forces, air defense threats vary considerably. In regional conflicts, where forces with similar capabilities are involved and no air-superiority can be achieved, the role of air defense systems becomes critical. In combat terrains containing mountains (in mainland or in small islands), the man-operated or computer-controlled (using passive sensors) anti-aircraft artillery can be highly effective. The simulator presented in this work aims to exploit the capabilities provided by current commercial-off-the-shelf (COTS) communication and multimedia technologies for providing a training environment that improves the personnel capability for effective use of man-controlled anti-aircraft weapons.

This paper addresses an accelerated track for military veterans into bachelor's degrees in engineering. It is an update on a project that was first reported at FIE 2011. An initial thorough evaluation of the veterans' training, experiences, and expertise has been conducted with the option of granting academic credit where appropriate. Therefore, it is important to have contact with the military veteran prior to their arriving on campus to begin their schooling. Current policies give little credit for military experience or training. The development of on-line pre and post assessments and subject based tutorials are being used to accelerate the veteran's entry into the traditional math sequence. Veterans may have a base of technical knowledge acquired through the technical nature of their service posts. Assigning them to introductory level courses with traditional freshman and sophomore students does not respect their technical expertise nor challenge their capabilities and accustomed pace.

Aimed at the design of distribution layer in defense works, the advances in distribution research were summarized and analyzed. Perfect distribution layer should be economical, practicable, reliable and have enough static/dynamic strength, which should weaken the stress waves and absorb the energy deriving from explosion to the greatest extent under the repeated impact loadings. And the development tendency was discussed. The results show: the main materials in distribution layer are still concrete or soil in the present stage and next period of time, and the perfect structure should be the combination of layered structure and cavities-contained structure. All those can be referenced for the design of advanced distribution layer in defense works.

One of the major unintended consequences of Acquisition Reform efforts during the 1990s was a reduction in rigor of sustainment planning and effectiveness throughout materiel development programs. As the evidence of this problem mounted over the past decade, the Department of Defense (DoD) initiated efforts to rejuvenate sustainment planning during the early phases of program development. This article provides brief descriptions of the actions that have been taken, or that are being planned, to achieve this goal.

The Defense Standardization Program Office (DSPO) of the U.S. Department of Defense's (DoD) has initiated a multiphase effort to update MIL-HDBK-217 (217), the military's often imitated and frequently criticized reliability prediction bible for electronics equipment. This document, based on field data fitted empirical models, has not been updated since 1995. The lack of updates led to expectations that its statistically-based empirical approach would be phased out. Especially after science-based Physics of Failure (PoF) [a.k.a. Reliability Physics] research led Gilbert F. Decker, Assistant Secretary of the Army for Research, Development and Acquisition to declare that MIL-HDBK-217 was not to appear in Army RFP acquisition requirements as it had been “shown to be unreliable and its use can lead to erroneous and misleading reliability predictions”[1].

In this paper, we analyze the motivation of the cooperative R&D between private S&T enterprises and state military companies from the angle of informal innovation network. The military industry is a natural monopoly industry which regulated by government. As a result, the informal innovation is a valuable way for private S&T enterprises to entry into the industry by cooperating with state military firms. By investigation we find that there are special motivations for the partners. Through informal network, they can achieve the following motivation: Mastering the civil technology, gaining the official R&D fund, enhancing the social status of private enterprises, strengthening the contact with government officials. Finally, we analyze the rules of the cooperative R&D by mathematical method.

The Turkish defense industry has been growing significantly since 1970s. The majority of the $416 million USD reserved for R&D budget in 2005 was spent for defense and aerospace industry. The total revenue of the defense companies in Turkey was around $2.2 billion USD in 2008. The Undersecretariat for Defense Industries (SSM) of Turkey aims to increase the average portion to meet the system requirements through local infrastructure to 50 percent and also to increase the export of defense services and goods to 1 billion USD by 2011. SSM also plans to quadruple the portion of Turkish defense industry in the NATO projects. Companies operating in the defense sector utilize the latest technologies and they have to cope with the fast pace of changes in the technology. On the other hand, the Turkish defense industry is growing significantly and aiming to keep and even accelerate this growth. Therefore, technology management plays a vital role in Turkish defense industry and this research investigates the current status of technology management in the Turkish defense industry.
