Profiling the Desirable CAD Trainee: Technical Background, Personality Attributes, and Learning Preferences
Ramsey F. Hamade
This research aims to explore some of the underlying reasoning for why some individuals acquire mechanical computer-aided design (CAD) skills with relative ease while some others seem to falter. A methodical study was performed by monitoring 74 mechanical engineering seniors (over a 3 year period) i ... [J. Mech. Des. 131, 121009 (2009)] published Wed Nov 18, 2009.

Simple mechanical analogs of rapid adiabatic passage in atomic physics
B. W. Shore, M. V. Gromovyy, L. P. Yatsenko, and V. I. Romanenko
We discuss two mechanical systems in which the approximate equations of motion are the same as the rapid adiabatic passage of a two-state quantum-mechanical system, such as that which occurs with quasistatic interactions and from the quasiperiodic action of a chirped-frequency laser pulse. We discus ... [Am. J. Phys. 77, 1183 (2009)] published Tue Nov 17, 2009.
Interference with polarized light beams: Generation of spatially varying polarization
B. M. Rodriguez-Lara and I. Ricardez-Vargas
We propose a method based on a MachZehnder interferometer to analyze the superposition of polarized laser beams at a given angle. The focus of our study is the spatially varying polarization state of the resulting field, also known as a polarization grating, generated by this setup. Our proposal com ... [Am. J.

Raman scattering of carbon disulfide: The temperature effect
Dake Wang, Kathryn Mittauer, and Nicholas Reynolds
A low-cost Raman system was constructed and used to perform Raman scattering measurements on liquid carbon disulfide at different sample temperatures. The nu and nu bands are identified based on the frequencies calculated by the normal mode analysis. The ratio of the intensities of the anti-Stokes a ... [Am. J.

Quantitative analysis of the electric dipole on finite sized graphite sheets
David Groh
Graphite sheets are commonly used in introductory physics laboratories to model electric potential patterns for systems such as dipoles and parallel plates. Usually, silvered ink pens are used to draw patterns on the sheets and appropriate voltages are then applied. Quantitative experiments are ofte ... [Am. J.

On thermionic emission and the use of vacuum tubes in the advanced physics laboratory
Paul J. Angiolillo
Two methods are outlined for measuring the charge-to-mass ratio e/m of the electron using thermionic emission as exploited in vacuum tube technology. One method employs the notion of the space charge in the vacuum tube diode as described by the ChildLangmuir equation; the other method uses the elect ... [Am. J.

A water wave analog of the Casimir effect
Bruce C. Denardo, Joshua J. Puda, and Andres Larraza
Two rigid plates are vertically suspended by thread such that they are parallel to and opposite each other. The plates are partially submerged in a dish of liquid that is attached to the top of a vertical shake table. When the shake table is driven with noise in a frequency band, random surface wave ...

Electronic whiteboard construction using whiteboard and image-locating techniques
Wen-Yuan Chen, Jing-Wein Wang, and Chin-Ho Chung
We use image-locating techniques and a traditional whiteboard with two cameras to construct an electronic whiteboard (EWB) with a size of 88 x 176 cm corresponding to 1280- x 1024-pixel resolution. We employ two strategies achieve the goal: (1) we develope a modified scale and bilinear interpolatio ... [Opt. Eng. 48, 117202 (2009)] published Thu Nov 12, 2009.

Are Students' Responses and Behaviors Consistent?
Umporn Wutchana, Narumon Emarat, and Eugenia Etkina
In our project we attempted to determine if students whose beliefs about physics are more expert-like and less expert-like, as judged by the CLASS survey, are different in terms of their approaches to learning physics and whether their behaviors in the classroom are consistent with their responses t ...

Comparing Three Methods for Teaching Newton's Second Law
Michael C. Wittmann, Mindi Kvaal Anderson, and Trevor I. Smith
As a follow-up to a study comparing learning of Newton's Third Law when using three different forms of tutorial instruction, we have compared student learning of Newton's Second Law (NSL) when students use the Tutorials in Introductory Physics, Activity-Based Tutorials, or Open Source Tutorials.

Fourth Graders' Framing of an Electric Circuits Task
Victoria Winters and David Hammer
Previous work shows that college students have more difficulty lighting a bulb with a single wire and a battery than with two wires [1], results that have informed the design of activities [2].
