Sometimes, the use of the global vehicle dynamic model is not needed to analyse and develop some applications in vehicle. For example, for the passenger comfort only the sub-model of the suspension is needed. In this context, this paper deals with a splitting of dynamic model for vehicle into five sub-models each one describing a subsystems regrouped in three blocks. The novelty of this idea consists...
The problem of providing source authentication in Wireless Sensor Networks (WSNs) has been a roadblock to their large scale deployment, and is still in its infancy. In this paper, we present novel symmetric-key-based authentication schemes which exhibit low computation and communication authentication overhead. Our schemes are built upon the integration of a reputation mechanism, a Bloom filter, and...
Purpose To evaluate the impact of country socioeconomic status and hospital type on device-associated healthcare-associated infections (DA-HAIs) in neonatal intensive care units (NICUs). Methods Data were collected on DA-HAIs from September 2003 to February 2010 on 13,251 patients in 30 NICUs in 15 countries. DA-HAIs were defined using criteria formulated by the Centers for Disease Control and Prevention...
This paper will show how to handle modeling of vehicles to get efficient and good Sliding Mode Observers. A car model with 16 DoF is decomposed for partial state observation with SMO. This decomposition method may lead, in VSAS, to good estimates of different kind variables and inputs (subsystems states, environment and ground variables, interfaces variables, connections and constraint variables)...
In this paper, we compare three observers and methods for estimation of the longitudinal and lateral velocity of the vehicle. These methods are based on the first order sliding mode (FOSM), second order sliding mode (SOSM) and on the use of algebraic approach ALIEN. Their performance are studied using a 16 DoF dynamic simulator.
