A new method of test-per-clock BIST design for combinational circuits is proposed. The fundamental problem of matching the PRPG outputs with the required test patterns is solved as a general design problem in the field of combinational logic. A test set generated by an ATPG is compared with the PRPG generated sequence. The solution is based on a novel search algorithm, which identifies the best...

an efficient method was employed for the ash and pyrite sulphur removal from bitumen using column flotation process. the bitumen samples containing 9.6% sulphur (6.81% in the pyrite sulphur form) and 26.4% ash were successfully showed up to 75.20% of pyrite sulphur (e.g.; 51.66% of total sulphur) and 70.81% of ash removal. the box-behnken design (bbd) was employed to design the experiments, to ...

Background and objectives: Perchloroethylene (PCE) is categorized as contaminant of concern because of its adverse health effects and persistence in drinking water resources. Permeable reactive barrier with zero valent iron (ZVI-PRB) is a passive zone in which chlorinated ethenes are degraded in situ through the chemical reduction mechanism. The objective of the present investigation was optimi...
