A family of LAN (Local Area Network) protocols is presented. The LAN consists of a pair of unidirectional fiber optic buses to which stations are connected via passive taps. The protocols provide round-robin bounded delay access to all stations. Contrary to most round-robin access schemes, the protocols do not require transmission of special packets(More)
An interesting strategy for improvement of a complex trait dissects the complex trait in a number of physiological component traits, with the latter having hopefully a simple genetic basis. The complex trait is then improved via improvement of its component traits. As first part of such a strategy to improve yield in pepper, we present genetic and QTL(More)
Many military training centers still use traditional means to train and practice air traffic control. To represent reality, they use physical models of an airfield and aircrafts, or advanced computer simulations. LMS systems are also frequently used for management of online contents of courses. We are connecting simulations with LMS systems, in order to(More)
– Spasticity is a common and complex motor disorder that affects more than 12 million persons in the world. There are several studies on spasticity quantification in the literature but there is still a need for measurement improvements. This paper presents the design of a mechatronic device for spasticity quantification, in joint of ankle, elbow and knees.(More)
Commutative Jordan algebras are used to drive an highly tractable framework for balanced factorial designs with a prime number p of levels for their factors. Both fixed effects and random effects models are treated. Sufficient complete statistics are obtained and used to derive UMVUE for the relevant parameters. Confidence regions are obtained and it is(More)
Today dashboards are a clear factor of differentiation for decision-makers, providing critical business indicators in useful time. They are very important data visualization mechanisms, simple to interpret, easy to deal, and fast on showing pertinent data. Dashboards provide means for reducing time of information analysis, disposing business indicators in(More)
This paper presents a robotic team suited for bottom sediment sampling and retrieval in mudflats, targeting environmental monitoring tasks. The robotic team encompasses a four-wheel-steering ground vehicle, equipped with a drilling tool designed to be able to retain wet soil, and a multi-rotor aerial vehicle for dynamic aerial imagery acquisition.
