We investigate whether there were common causes for the withdrawal from the regional aircraft market of three established manufacturers (BAE Systems, Fokker and Saab), while competitors thrived. We focus on the markets for 50and 100-seat aircraft. One cause concerning the 50-seat market was the introduction of a new class of aircraft, the regional jet, which pushed the less successful turboprop...

We extend some results of Rosenthal, Cembranos, Freniche, E. Saab-P. Saab and Ryan to study the geometry of copies and complemented copies of c0(Γ) in the classical Banach spaces C(K,X) in terms of the cardinality of the set Γ, of the density and caliber of K and of the geometry of X and its dual space X∗. Here are two sample consequences of our results: (1) If C([0, 1], X) contains a copy of c...

SLA-Aware Adaptive Data Broadcasting in Wireless Environments Adrian Daniel Popescu Masters of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto 2009 In mobile and wireless networks, data broadcasting for popular data items enables the efficient utilization of the limited wireless bandwidth. However, efficient data scheduling schemes are needed to ...

The role of NMDA receptors in oligodendrocytes has been controversial. A new paper (Saab et al., 2016) suggests they play a key role in regulating glucose uptake in response to axonal glutamate release, thus controlling metabolic cooperation between oligodendrocytes and axons.

Using data from extensive vibrational tests of the new aircraft Saab three di erent methods for vibration analysis are studied These methods are ERA eigensystem realization algorithm N SID a subspace method and PEM prediction error approach We nd that both the ERA and N SID methods give good initial model parameter estimates that can be further improved by the use of PEM We also nd that all met...
