Conventional external testing processes involve storing all test vectors and test responses on the automatic test equipment (ATE) memory. The test data volume for the scan-based test is normally very large due to its single pattern length generated using a combinational automatic test pattern generation (ATPG) tool. The test application time depends on the amount of test data stored on ATE, the time required to transfer the test data from ATE to the core and length of the scan chain. But these testers have limited memory, speed and I/O channels. Efficient test data reduction techniques can reduce the testing time, test power and ATE memory requirements. Three multistage compression techniques are introduced to reduce the test data volume in scan-test applications. The three encoding schemes namely equal run-length coding (ERLC), extended frequency directed run-length (EFDR) coding, alternating variable run-length (AVR) is used for computing the data. These encoding scheme together with nine coded (9C) technique enhance the test compression ratio. In the first stage, pre-generated test cubes with unspecified bits are encoded using nine-coded (9C) scheme. Later the three encoding schemes utilize the properties of compressed data to enhance the test compression. This multistage compression is effective especially when the percentage of don't care in a test set is very high. The experimental result obtained from ISCAS'89 benchmark circuit confirms the average compression ratio of 46%, 52%, 57% with the proposed 9C-ERLC, 9C-EFDR, 9C-AVR codes respectively.

Hydrogen is being considered as a flexible energy vector that could play an important part in this endeavour. With demonstration projects on the rise it is crucial to identify suitable odorants to ensure, safety regulations are met and public acceptance gained. Specifically, this work investigates the use of sulphur based odorants currently in use in the UK and Europe, alongside sulphur-free and experimental ones, for use in a 100% hydrogen gas demonstration network in the UK. Gas samples odorised with five different odorants are analysed to determine odour detection threshold, the odour intensity, its hedonic tone and character. The tests are performed by an accredited laboratory following EU standards. The results show that four odorants meet requirements as stenching agents for use in UK gas distribution network, whilst one, 5-ethylidene-2-norbornene, fails to demonstrate an unpleasant odour.
