The natural, prehuman abundance of most large predators is unknown because of the lack of historical data and a limited understanding of the natural factors that control their populations. Determining the supportable predator biomass at a given location (that is, the predator carrying capacity) would help managers to optimize protection and would provide site-specific recovery goals. We assess ...

Proof-carrying code approaches aim at the safe execution of untrusted code by having the code producer attach a safety proof to the code which the code consumer only has to validate. Depending on the type of safety property, proofs can however become quite large and their validation though faster than their construction still time consuming. Programs from Proofs is a new concept for the safe ex...

This paper deals with the prcblem of simulating the notions of a complex land vehicle moving in a natural environment. The contribution presented here is z motion generctor which predicts the dynamic behaviour of the vehicle when executing a given nominal motion plan. This ptan is expressed in terms of a channel to follow and of a set of intermediate subgoals to reach. Solving this motion gener...

Nowadays, with highly developed instrumentation, sensing and actuation technologies it is possible to foresee an important advance in the field of autonomous and semi-autonomous transportation systems. Among the most promising transport infrastructures the articulated bus is an interesting, low cost and friendly option. In this paper an experimental set-up for research on automatic control of a...

Articulation angle sensing is an essential component of manoeuvrability and stability control systems for articulated heavy goods vehicles, particularly long combination vehicles. Existing solutions to this task are limited by reliance on trailer modifications or information measurement accuracy, both, restricting commercial adoption. In paper we present a purely tractor-based sensor concept co...

Mesomorphic alkyne-based first- and second-generation dendrons were grafted onto gold nanoparticles carrying azide groups under click reaction conditions. The nanoparticles decorated with the dendrons displayed liquid-crystalline properties and good thermal stability.

 Abstract A 2.5 year old girl is presented with both hands constriction bands leading to distal amputations and the rare deformity of shoulder duplication in the right side accompanying constriction skin marking over the affected shoulder. The cephalomedial scapula articulated with the clavicle and the caudolateral scapula articulated with humeral head. The most important physical finding which...
