Development of vibration loading profiles for accelerated durability tests of ground vehiclesXu, Ke 06 September 2011 (has links)
The accelerated durability test is an important part for design and manufacturing ground vehicles. It consists of test designed to quantify the life characteristics of a ground vehicle component under normal use conditions by testing the unit at higher stress levels to accelerate the occurrence of failures. The challenge of conducting accelerated durability tests is to create the driven profile. In general, the mission profiles of the accelerated durability test can be generated via the acceleration data of the events experienced by the vehicle during the field test. Accurately separating the time series signal that correlate the load events becomes essential to efficiently generate the mission profiles for the accelerated test analysis. The representative Power Spectrum Density (PSD) profile can be generated based on the mission profiles. Then, the driven profile for the sub-scaled accelerated durability test, i.e., the acceleration data can be generated based on the PSD data.

Effects of lithium on rats' activity levels and on reaction to environmental stimulationCappeliez, Philippe, 1951- January 1980 (has links)
This research investigated the effects of different doses of lithium on rats' behavior in an attempt to understand lithium's therapeutic mechanism of action in major affective disorders. / Although high doses (1.50 mEq/kg LiCl) decreased rats' open field activity, low doses (0.15 mEq/kg LiCl) increased activity, which is a new finding. A study of the effects of these two doses on reaction to environmental complexity and novelty suggested that, irrespective of dose, lithium increases readiness to engage in inspective exploration of a novel environment and promotes longer inspective exploration of a known complex environment. This was interpreted as increased selective attention to stimuli providing relevant information about the environment. The prediction derived from these findings, that both doses would decrease distractability, was supported in an experiment on tone-induced suppression of licking. / A two factor (activity, selective attention) model of lithium's action was proposed and its relevance to lithium's clinical efficacy in major affective disorders was discussed.
