Majority of Malaysian motorcycle fatalities have occurred along straight road sections, which are mostly two-lane undivided roads with several small junctions or access points. In order to gain more insight into the actual road traffic situation and the course of events on these sites because, an observational and traffic conflict study, focusing on motorcyclists, was conducted by the author betwe
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
