Automation of Photoluminescence Measurements of Polaritons

Methods of automating experiments that involve the variation of laser power are discussed. In particular, the automation of photoluminescence measurements of polaritons is examined through the use of various programs and devices such as a laser power controller and a spectrometer. Additionally, the theory behind the experiment and the laser power controller is briefly discussed. Acknowledgement...

Automation of Vapour Pressure Osmometry measurements

A program has been developed for the control of Vapour Pressure Osmometry (VPO) measurements. The output signal of a Vapour Pressure Osmometer is read by an A/D converter card installed in one of the expansion slots of a PC microcomputer. The stability of the measurements is checked by analysing the first derivative of the smoothed signals, which is calculated in real time. Sets of repeated mea...

Automation of Subjective Measurements of Logatom Intelligibility in Classrooms

A great number of rooms are dedicated to a voice communication between a singular speaker and a group of listeners. Those rooms could be as small as meeting room and classrooms or larger like auditoriums and theatres. There is a major demand for them to assure the highest possible speech intelligibility for all listeners in the room. Classrooms are an example of rooms where a very good speech i...
