The use of industrial robots in the aircraft industry has been hampered by a combination of poor accuracy of the robots and poor calibration of the workcell, and also manufacturing variability in composite parts. A way to handle these difficulties is using force control. An experimental case where a semi-compliant rib is aligned to multiple surfaces is used as an example to show this. The constrai
Regional cerebral blood flow (rCBF) was measured by the 133Xenon inhalation method in nine male chronic cannabis users. The rCBF level in cannabis users was significantly (11%) lower than that of age- and sex-matched healthy controls. Four of the subjects were reexamined after 9-60 days of detoxification and showed a significant (12%) increase of the CBF level at followup. No significant regional
This paper presents a hardware implementation of a high quality acoustic echo canceller for use in handsfree telecommunication systems. The implementation is based on an algorithm with no delay in the signal path, attractive for communication systems where low delay is crucial. However, a zero delay algorithm has higher complexity compared to other canceller solutions. A custom silicon implementat
This manuscript presents simulation results of energy dissipation in sub-threshold (sub-VT ) of various 16-bit adder structures. The architectures designed for the comparative experiments are, a bit-serial, an 8-bit digit-serial and a 16-bit parallel adder structures. The designs are synthesized in a 65 nm low-leakage high-threshold CMOS technology. The results show that an energy minimum operatin
