In this paper, we revisit the hydrodynamics supporting design and development of RiverCat class catamaran ferries operating in Sydney Harbor since 1991. More advanced software is used here. This accounts for transom demisterns that experience partial or full ventilation, depending on vessel speed. ventilation gives rise to hydrostatic drag, which adds total drag vessel. The presence also create...

This study is concerned with the active T-foil placed near bow on keel line of fast ferry and two trim tab controls at stern to improve maritime performance a ferry, whilst improving comfort safety passengers crew. In scope study, vertical direction under random head waves, heave pitch motions were taken into account. For control Tabs, PID LQR methods used. The purpose these controllers reduce ...

Coherence is a fundamental tool in the analysis of neuronal data and for studying multiscale interactions of single and multiunit spikes with local field potentials. However, when the coherence is used to estimate rhythmic synchrony between spiking and any other time series, the magnitude of the coherence is dependent upon the spike rate. This property is not a statistical bias, but a feature o...

R ecently there’s been a push among some of our clients to start bringing 3d imaging systems in-house. In the majority of cases the client wants my company to provide some form of training to help them get off on the right foot. Although we are in the consulting business, training is a different animal. We’ve worked for years, continuously refining our processes and tools, investing in R&D and ...

Pyocyanin is a toxin produced by Pseudomonas aeruginosa. Here we describe a novel paper-based electrochemical sensor for pyocyanin detection, manufactured with a simple and inexpensive approach based on electrode printing on paper. The resulting sensors constitute an effective electrochemical method to quantify pyocyanin in bacterial cultures without the conventional time consuming pretreatment...
