An experimenter uses an X-ray spectrometer which has a rotating drum scale and a pointer to measure angles. A view of this scale is shown in the attachment.
a) It is expected to measure an X-ray peak which occurs at an angle of around 31.6 degrees. After viewing the scale and pointer, with what accuracy will you quote the result?
b) A preliminary set of measurements are made in which little care is taken in making the measurements (e.g. not always approaching from the same direction, careless estimation of position etc). Five repeated measurements in degrees are as follows:
30.8, 31.3, 31.8, 31.7, 32.2
Is this acceptable? - if not, why not?
c) The mechanical linkages in the spectrometer are adjusted to remove 'backlash', and care is taken to always approach the measurement in the same direction. Five repeated measurements in degrees are as follows:
31.2, 31.3, 31.7, 31.6, 31.7
Is this acceptable? If so what is the measured angle of the peak.© BrainMass Inc. brainmass.com October 25, 2018, 9:19 am ad1c9bdddf
Least count of the measuring scale = 0.5 degree
As the pointer is between 31.5 and 32.0
Hence, measured value will be = 31.5 + 0.5/2 = 31.75 = 31.8 (rounded off to 1st ...
Through an example problem, accuracy of measurement is discussed.
Measurement and improvement processes - Pharmaceuticals company
Organization selected for the project is a Pharmaceuticals company. I need help in finding information for section 6 (Measurement process) and 7 (Improvement process). If you could give me some ideas and push me in the right direction, I would greatly appreciate it.
Select a health care organization and write a plan for what you consider to be an ideal performance management system. You are to turn in an outline of the presentation in Week Three and the presentation in Week Five. Be sure to include the following elements in your presentation:
1. Organization's mission statement
2. Standards and scope
3. Government regulations and accreditation organizations' influence
4. Findings of a Quality Director's functions, roles, and challenges through an interview (please use the consent form provided in the Materials section of the resource page)
5. Performance awareness
6. Measurement process
7. Improvement process
8. Any specific framework or approach used, and how results are communicated
