This thesis covers the use of a quarter car model to select damping rates for aFormula Student (FS) car, focusing on minimizing vertical tire force variation to improvegrip. A 2 degree of freedom (DOF) quarter car model is cycled over the road frequenciesof interest and the results compared with the...
Wood density is controlled to a large extent by the relative widths of earlywood and latewood in the stem, but the mechanisms controlling these amounts are poorly understood in coastal Douglas-fir. To understand the role of climatic factors, one hundred and thirty-six increment cores were collected and measured from the...
Effects of inbreeding coho salmon (Oncorhynchus kisutch) on
survival during early life history, growth, feed efficiency, and
resistance to gas bubble disease were studied. No effect of inbreeding
could be associated with either F=0.25 or F=0.125. Tetraploidy
may help explain the absence of inbreeding depression at these
levels.
This paper presents a Hypothetical Storage Server for an experimental design database system. The storage server provides unified management of historical versions and hypothetical versions of objects in a design database. The extension of each database object is man.aged as a tree of multiple distinct representatives. One branch of the...
En dépit de sa production halieutique qui occupe la première place dans le monde arabe et africain, le Maroc connaît une consommation de poisson de 7.5 Kg/personne/an, largement inférieure à la moyenne mondiale qui est voisine de 13 Kg/personne/an. Cette consommation est inégalement répartie. Généralement moyenne à forte, en bordure...
