Quality in higher education can be considered as a form of endurance, luxury, conformance to requirements, continuous improvement and value added. The difficulty in improving quality in higher education stems from using different frameworks and measurement issues. The combination of summative assessment, formative assessments and assessment of activities which imply student learning as the best approach for quality in higher education is explained.

Testing and measurement of quality are essential processes in a foundry. Testing, inspection and measurement are important in each casting production process, starting with pattern and die design, moldmaking and coremaking, chemical analyses of heats, and finishing. Quality control processes include hardness testing, leak testing, visual inspection, fracture tests, liquid penetrant inspection, magnetic particle inspection, machine vision, ultrasonic testing, eddy current testing, radiography and spectrography., High quality castings depend on the ability of a foundry to test and inspect all raw materials - sand, metals, alloys, and additions. Testing, inspection, and measurement are critical in [...]

Low process yields require that complex ASICs have test programs with high fault coverage. Unfortunately, conventional methods of automatic-test-pattern generation attempt to create test vectors by considering only the structural […]

A critical element in a digital transmission system is how error-free its transmissions are. This measurement is made by a bit-error-rate tester (BERT), which replaces one or more of the […]

Computer-aided engineering (CAE) tools can help pc-board designers predict and correct transmission-line effects in all stages of design. Designers can use tools before beginning board layout, following component placement and after routing. Tools can either be for analysis or screening. Analysis tools examine individual signal traces and allow for study of the circuit's behavior in detail using simulated waveforms. Analysis tools are good for establishing design rules before beginning pc-board layout. Screening tools allow designers to check for transmission-line effects after they know what the circuit will tolerate. Screening tools all calculate transmission-line effects but calculate them in different ways. Different vendors have tradeoffs between speed and accuracy. Designers need to evaluate the accuracy they need as well as cost and computer type when choosing CAE tools.
