Evolution And Rationale For United States Department Of Defense Electromagnetic Pulse Protection Standard, George H. Baker Iii
Evolution And Rationale For United States Department Of Defense Electromagnetic Pulse Protection Standard, George H. Baker Iii
George H Baker
The United States (US) Department of Defense (DoD) Electromagnetic Pulse (EMP) protection standard offers a solid basis for protecting commercial communication, data, and control facilities. Because of the standard’s shielded barrier and test requirements, it is not surprising that there is a strong temptation within industry and government to dismiss the MIL-STD 188-125 approach in favor of less rigorous protection methods. It is important to understand that US DoD EMP protection standard for fixed facilities, MIL-STD-188-125, reflects an evolution by trial and error that spanned a period of decades beginning with the acquisition of the Minuteman Missile System in the …
Proposal For A Dod Combined Battlefield Electromagnetic Environmental Effects (E3) Initiative, George H. Baker Iii
Proposal For A Dod Combined Battlefield Electromagnetic Environmental Effects (E3) Initiative, George H. Baker Iii
George H Baker
The presentation emphasizes the growing importance of electromagnetic survivability and compatibility. Operation Desert Storm demonstrated the clear military advantage provided by sophisticated electronic weapon and communication systems. In addition, the offensive tactic of taking out the enemy's eyes and ears during the air war paid off, giving our military decisive air superiority. The lessons for the future are clear. High-tech electronics now so dominates the battlefield that the outcome of future conflicts could well be decided by electronics attrition rather than human casualties. Our Desert Storm experience thus accentuates the importance of guaranteeing that our electronic systems will not be …
Testimony Of Dr. George H. Baker, Senior Advisor To The Congressional Emp Commission, George H. Baker Iii
Testimony Of Dr. George H. Baker, Senior Advisor To The Congressional Emp Commission, George H. Baker Iii
George H Baker
This is the script of testimony before the Federal Energy Regulatory Commission. It offers a vision for a future in which our electric power systems will be able to operate through or quickly recover from catastrophic failure due to electromagnetic pulse (EMP), cyber, and physical attacks. The scope of the term ‘EMP’ used in this testimony includes both naturally occurring solar storms and the more energetic man-made EMP hazards. The vision has been discussed with members of the electric power industry, and prominent EMP/cyber/physical protection advocates who find it to be supportable and actionable. The nature of EMP, cyber, and …

Impulse-Momentum Diagrams, David Rosengrant

Multiple representations are a valuable tool to help students learn and understand physics concepts. Furthermore, representations help students learn how to think and act like real scientists. These representations include: pictures, free‐body diagrams, energy bar charts, electrical circuits, and, more recently, computer simulations and animations. However, instructors have limited choices when they want to help their students understand impulse and momentum. One of the only available options is the impulse‐momentum bar chart. The bar charts can effectively show the magnitude of the momentum as well as help students understand conservation of momentum, but they do not easily show the actual …
Following Student Gaze Patterns In Physical Science Lectures, David Rosengrant, Doug Hearrington, Kerriann Alvarado, Danielle Keeble
Following Student Gaze Patterns In Physical Science Lectures, David Rosengrant, Doug Hearrington, Kerriann Alvarado, Danielle Keeble
David Rosengrant
This study investigates the gaze patterns of undergraduate college students attending a lecture-based physical science class to better understand the relationships between gaze and focus patterns and student attention during class. The investigators used a new eye-tracking product; Tobii Glasses. The glasses eliminate the need for subjects to focus on a computer screen or carry around a backpack-sized recording device, thus giving an investigator the ability to study a broader range of research questions. This investigation includes what students focus on in the classroom (i.e. demonstrations, instructor, notes, board work, and presentations) during a normal lecture, what diverts attention away …
Pre-Service Physics Teachers And Physics Education Research, David Rosengrant
Pre-Service Physics Teachers And Physics Education Research, David Rosengrant
David Rosengrant
Training pre-service teachers requires, among other things, content knowledge, pedagogical skills and pedagogical content knowledge. Teacher preparation programs have little, if any spare time to add more courses/activities to their program. However, I argue in this paper that we, as educators, must enhance the amount of physics education research in our pre-service physics teacher training programs. In this study, I analyze the results of two different types of exposure to physics education research (PER) from two different groups of pre-service physics teachers in our masters of arts and teaching program. The preliminary results show, for example that the PER helped …
