Par le théorème de la limite centrale, cette variable converge en loi vers la loi normale centrée réduite, c’est-à-dire, pour tout t ∈ R, on a limn→+∞ E[eitZn ] = e− t2 2 . L’objet de cet exercice est de montrer que la suite Zn ne peut pas converger en probabilité. 1. Calculer la fonction caractéristique de Z2n − Zn et montrer que cette différence converge en loi. 2. En étudiant P(|Z2n − Zn| ≥ ...

Physiological considerations in seating.

Physiological changes occur with change of posture. Seating imposes significant effect on the cardiovascular, respiratory, abdominal, renal and neurological systems. The presence of severe skeletal deformities can significantly alter the physiological responses of the individual to changes in posture. In the case of severe kyphoscoliosis profound haemodynamic changes may occur. Lung perfusion h...

Introduction aux variétés différentiables Solutions et Exercices

Solution 12.1. Let ∑ α∈A ηα be a partition of unity supported on the coordinate charts of the orientable manifold. Let φα : Uα → Rn be the orientable coordinate charts, and let xα, . . . , xα. Then for each α define an n form on M by ωα = ηαdxα∧ · · · ∧dxα. This is smooth in Uα because it is a product of a smooth form and function. Outside of Uα the form is zero in a neighbourhood of every poin...

A dynamic seating intervention for wheelchair seating discomfort.

OBJECTIVE The objective of this study was to examine the effectiveness of a new user-adjustable wheelchair seating system designed to relieve discomfort for long-duration wheelchair users. DESIGN This objective was carried out using the newly developed Tool for Assessing Wheelchair disComfort (TAWC) as the primary outcome measure. Two wheelchair users each tested two different designs and fee...
