We investigated the relationship between microstructure and mechanical properties of Ti–6Al–4V alloy subjected to friction welding (FW). In this work, specimens with a diameter 15 mm length 50 were prepared, FW was performed at constant rotation speed (1600 rpm) different upset lengths (1 3 mm). The electron backscattered diffraction (EBSD) method used analyze grain boundary characteristic dist...

Abstract In high-energy physics experiments, it is a trend to implement digitalization in the front end of readout electronics based on Application Specific Integrated Circuits (ASICs), which are exposed radiation environment. As an important part ASIC, SRAM (Static Random-Access Memory) impressionable Single Event Upset (SEU) due Therefore, new SEU-tolerant cell structure was designed our prev...

We present an extensive statistical analysis of the results of all sports competitions in five major sports leagues in England and the United States. We characterize the parity among teams by the variance in the winning fraction from season-end standings data and quantify the predictability of games by the frequency of upsets from game results data. We introduce a mathematical model in which th...

Assessment feedback can have an emotional impact on students. This research contributes to the existing body of literature students’ reactions assessment through investigating negative responses summative experienced by first-year students at two UK universities. The majority learners interviewed indicated that their initial had a and demotivated them. For some these emotions were very serious ...
