Risk-Based Critical Infrastructure Priorities For Emp And Solar Storms, George H. Baker Iii
Risk-Based Critical Infrastructure Priorities For Emp And Solar Storms, George H. Baker Iii
George H Baker
Two electromagnetic phenomena have the potential to create continental-scale disasters. The first, nuclear electromagnetic pulse (EMP), results from a nuclear detonation high above the tropopause. The second, a major solar storm, or "solar tsunami" occurs naturally when an intense wave of charged particles from the sun perturbs the earth's magnetic field. Both phenomena can debilitate electrical and electronic systems necessary for the operation of infrastructure systems and services. One reason why a U.S. protection program has yet to be initiated is that policy makers continue to wrestle with the question of where to begin, given the Department of Homeland Security’s …

The Crisis In Ict Education: An Academic Perspective, Tony J. Koppi, Fazel Naghdy, Joe F. Chicharo, Judy Sheard, Sylvia Edwards, David Wilson
Professor Fazel Naghdy
A national Discipline-Based Initiative project for ICT, funded by the ALTC, has sought to identify the issues and challenges facing the sector. The crisis in ICT education spans high schools, universities and industry. The demand for skilled ICT graduates is increasing yet enrolments are declining. Several factors contribute to this decline including the perceived quality of teaching and a poor perception of the ICT profession amongst the general public. This paper reports on a consultation process with the academic community. Academic concerns include the capacity of the sector to survive the downturn, and improving relationships with industry which should benefit …

Issues In Australian Ict Education, Tony J. Koppi, Fazel Naghdy, Joe F. Chicharo
Professor Fazel Naghdy
This session at the Australian Software Engineering Conference is concerned with ICT education from the holistic perspective of preparation in high schools, the university experience, transition to the workforce, and the contribution by industry, government, and professional bodies. The project to ascertain the issues and challenges facing the national ICT education sector is supported by the Carrick institute as a discipline-based initiative. Consultations to date with various stakeholders have revealed numerous concerns that include: the dispersed nature of the ICT sector; erroneous perceptions of ICT disciplines; decline in enrolments; gender imbalance; lack of industry involvement; and balancing knowledge with generic …

Ict Education: Challenge Of Accommodating Change, Fazel Naghdy, Anthony Koppi, Joe Chicharo
Professor Fazel Naghdy
lobally, the Information and Communications Technology (ICT) sector has gone through significant and radical changes over the last 30 years. The development of computers, desktop and laptop computing, substantial development of software, emergence and swift acceptance of Internet and electronic communication, meteoric rise of the industry in the 90ýs and the ýdot.comý and telecom crash of the following years can be mentioned as significant events in the evolution of ICT industry.
Risk-Based Critical Infrastructure Protection Priorities For Emp And Solar Storms, George H. Baker Iii
Risk-Based Critical Infrastructure Protection Priorities For Emp And Solar Storms, George H. Baker Iii
George H Baker
The Commission to Assess the Threat to the United States from Electromagnetic Pulse Attack has provided a compelling case for protecting civilian infrastructure against the effects of EMP. As with protecting infrastructure against any hazard, it will be important to take a risk-based priority approach for EMP, recognizing that it is fiscally impracticable to protect everything. In this regard, EMP is particularly challenging in that it interferes with electrical and electronic data, control, transmission, and communication systems organic to nearly all infrastructures in a simultaneous and wide-scale manner. And, for nuclear burst altitudes of 100s of kilometers, the exposed geography …
Emp: A Brief Tutorial, George H. Baker Iii
Emp: A Brief Tutorial, George H. Baker Iii
George H Baker
A nuclear detonation at altitudes from about 30 to 500 kilometers generates a strong electromagnetic pulse (EMP) that propagates to points on the ground within the line-of-sight of the burst. For bursts above 100 kilometers, electronics can be affected over continental scale areas. The EMP induces large voltages and currents in antennas and cables of electronic systems that will upset operation or damage circuit components if protection measures are not present. The article provides a brief tutorial on EMP environments, effects and protection.
High Power Electromagnetic Weapons: A Brief Tutorial, George H. Baker Iii
High Power Electromagnetic Weapons: A Brief Tutorial, George H. Baker Iii
George H Baker
High power electromagnetic weapons, also referred to as high power radiofrequency (HPRF) weapons, are a type of directed energy weapons. The system effects of high power electromagnetic environments are well recognized by world scientific and military communities. Former CIA Director John Deutch has said that, "the electron is the ultimate precision-guided weapon." In the course of the investigation ofnuclear EMP effects on electronics during the Cold War period, it became evident that garden variety, unprotected electronics would malfunction, in some cases burn out, in the presence of electromagnetic fields in the hundreds to thousands of volts per meter. The EMP …

Utilization Of E-Learning Tools, Virtual Machines, & Open Source Software To Enhance Graduate Systems Engineering Programs, Maurice Dawson, Darrell Burrell, William Emanuel
Utilization Of E-Learning Tools, Virtual Machines, & Open Source Software To Enhance Graduate Systems Engineering Programs, Maurice Dawson, Darrell Burrell, William Emanuel
Maurice Dawson
This paper is a report on the findings of a study conducted on a graduate systems engineering course at an urban university in a group learning environment. The course, IEGR 501 Introduction to Advanced Systems Engineering, was a sixteen week course which took students with backgrounds in Industrial Engineering, Electrical Engineering, and Mechanical Engineering and prepared them to understand the systems engineering subject matter more. As the future of education becomes more and more virtual it becomes essential that universities take full advantage of the available tools at their disposal.
