Analysis of load cell barrier data for accident...
AbstractThe National Highway and Traffic Safety administration (NHTSA) regularly connducts crash tests as part of their research and regulatory duties. The data from these crash tests are available to the public and can be downloaded over the internet. These data include information recorded during the crash test from accelerometers and load cells on the vehicle and in crash test dummies inside the vehicle. Often, when conducting a frontal impact test, an instrumented load cell barrier is used. This is a rigid, flat barrier instrumented with an array of load cells that the vehicle impacts during the test. The load cells measure the force exerted by the vehicle on the barrier over time and provide information about the force-deflection characteristics of the vehicle. The force-deflection characteristics of a vehicle can be very helpful to researchers and investigators involved in automobile accident reconstruction. While there are many methods that accident reconstructionists have used to derive, model and estimate the force-deflection properties of vehicles, load cell barrier data have been mostly ignored for use in accident reconstruction analyses.

15.26Istanbul Technical UniversityAbstractPartial disturbance decoupling problems are equivalent to zeroing the first, say k Markov parameters of the closed-loop system between the disturbance and controlled output. One might consider this problem when it is not possible to achieve zeros for all Markov parameters which is known as exact disturbance decoupling. Structured transfer matrix systems are linear systems given by transfer matrices of which the infinite zero order of each nonzero entry is known, while the associated infinite gains are unknown and assumed mutually independent. The aim in this paper is to derive necessary and sufficient conditions for the generic solvability of the partial disturbance decoupling problem for structured transfer matrix systems by dynamic output feedback. Here, generic solvability means solvability for almost all possible values for the infinite gains of the nonzero transfer matrix entries. The conditions will be stated by generic essential orders which are defined in terms of minimal weight of the matchings in a bipartite graph associated with the structured transfer matrix systems.Do you want to read the rest of this article?Request full-text
