In this paper, a new continuous observer is developed to determine range information (and hence the 3-dimensional (3D) coordinates) of an object feature moving with affine motion dynamics (or the more general Riccati motion dynamics) with known motion parameters. The unmeasurable range information is determined from a single camera provided an observability… (More)
—A new adaptive controller is developed for wheeled mobile robots with parametric uncertainty in the dynamic model. The main theoretical contribution is the modular manner in which the control law and parameter update law are designed. This feature allows for design flexibility in the selection of the update law, and can be exploited to improve the… (More)
Aeromonas hydrophila has been increasingly documented as a hardy organism responsible for severe infection in the compromised host. This case report illustrates how A hydrophila may survive prolonged freezing and how seafood shucking may cause sepsis. This report serves as a caution to the immunocompromised seafood lover.
Approximately 390 literature references (through spring 1986) were reviewed for mammalian whole embryo culture procedures, with particular attention to the development of those cultures as systems for teratogenicity testing. The existing procedures could be conveniently divided into three groups, which are defined by the periods of embryogenesis that they… (More)
