Seven key science and technology(S&T) emphasis areas for the program were identified: ship design tools, ship structuralmaterials, hydromechanics, advanced hull designs, ship propulsion, ship automation, andsystems integration.Following a workshop in 2002, several university consortia, consisting of teams ofcomplementary universities were formed under an ONR BAA to work with the newly formedCenter for Innovative Ship Design, NSWC-CD (CISD) (see for example, Keane et al.1).

/C planes, flies subsonic at very low Reynolds numbers. Anotherconsideration is thickness to chord ratio. While thicker wings have more drag, thicker wingsoffer advantages in other areas.5 The added volume gives space for fuel storage, structural load-bearing members, electronics, and control mechanisms. After scouring books for airfoils, the S8036 airfoil was selected because of its gradualdrag polar. According to Lyon, at Reynolds Number 400,000, the S8036's drag coefficient doesnot increase noticeably with the lift coefficient until a very extreme lift coefficient is achieved.7This relationship is ideal because the UAV operates over a range of velocities, and is, therefore,conducive to a slight, gradual change in drag with lift

TAs A and B were both enrolled in the special topics coursewhereas TA E did not take the special topics course. With the exception of ‘demonstratesknowledge’ TAs A and B outperform TA E by approximately 1 point. TA E was expected tohave an equal if not higher score on ‘demonstrates knowledge’ because TA E is a post-doctoral.The data, as shown in Figure 1, suggests that TA E does not effectively demonstrate properties ofintellectual merit, which may be a consequence of limited understanding of the importance ofintellectual merit on teaching effectiveness.

The cognitive domain taxonomy is widely accepted in many fields and has beenidentified as, “arguably one of the most influential education monographs of the past halfcentury.”6 The taxonomies are a language that describes the progressive development of anindividual in each domain and are defined as follows7: • Cognitive: of, relating to, being, or involving conscious intellectual activity. • Affective: relating to, arising from, or influencing feelings or emotions. • Psychomotor: of or relating to motor action directly proceeding from mental

An entire section of the OSHA code (29CFR1910.217) is specifically devoted torequirements of safeguarding mechanical power presses. Mechanical press safety is alsoaddressed explicitly in ANSI B11.1. In the mid-1990’s the identification of presses as a serioussafety risk, particularly for amputations, led to the initiation of a focused OSHA emphasisprogram on press safety entitled, “CPL 2-1.24, National Emphasis Program on MechanicalPower Presses, 29CFR1910.217.”To provide better insight into the problem of press injuries
