Raman Spectroscopy Setup and Experiments for the Advanced Undergraduate Lab
Raman Spectroscopy is an important characterization technique in analytical chemistry and in solid state physics. This contribution describes the redesign of a Raman experiment for the Advanced Physics Lab and shows experimental results acquired with this new setup. Solid and liquid samples are irradiated by a frequency doubled Nd:YAG laser in backscattering geometry. The emission is focused on...
متن کاملAc 2007-232: Cost-effective Process Control Lab Setup
Many four-year engineering technology programs require or offer course(s) that emphasize examining the transient behavior of systems. The systems can be mechanical, electrical, chemical, or any other engineering discipline. These courses are generally classified as classes covering control system theory. Unfortunately, examining the transient behavior of control systems is very difficult in a l...
متن کاملAn ultrasonic device for source to skin surface distance measurement in patient setup.
PURPOSE To develop an ultrasound-based source to skin surface distance (SSD) measurement technique and device for patient setup and test its feasibility and accuracy. METHODS AND MATERIALS The ultrasonic SSD measurement device (USD) prototype consists of two main parts: a probe plate with an ultrasonic transducer in the center and a control unit that displays the SSD in millimeters. The probe...
متن کاملCircular Questioning: An Introductory Guide*
This paper presents a simplified model that has been found to be useful for those learning questioning skills within the Milan systemic approach to family therapy as well as for those who simply wish to develop some skills in circular interviewing. The model begins with the premise that clients frequently describe a problem in terms that are either too broad or too narrow. The model has two cat...
متن کاملQuestioning Representations
The role of models in the design of computer systems to support interpersonal and cooperative work is examined. It is argued that the current generation of models over-emphasise determinism at the expense of interpretation in the work process. It is further argued that there are many cases in which designs pass between many different professional groups (office workers, managers, analysts, desi...
