Abstract Research of pressure sensor chip utilizing novel electrical circuit with bipolar-junction transistor-based (BJT) piezosensitive differential amplifier negative feedback loop (PDA-NFL) for 5 kPa range was done. The significant advantages developed PDA-NFL in the comparative analysis advanced analogs, which are using Wheatstone piezoresistive bridge, clearly shown. experimental results p...

With the implementation of regional coordinated development strategy, traffic flow has grown explosively. The construction a larger tunnel section becomes an effective way to solve highway network’s insufficient transport capability problem. Currently, there is little research on factors influencing and methods calculating loose pressure in surrounding rock mass for tunnels with super-large cro...

We present a new criterion for connuence of (possibly) non-terminating left-linear term rewriting systems. The criterion is based on certain strong joinabil-ity properties of parallel critical pairs. We show how this criterion relates to other well-known results, consider some special cases and discuss some possible extensions.
