An analysis and design method is presented for the design of composite sandwich cover panels that includes transverse shear e ects and damage tolerance considerations. This method is incorporated into a sandwich optimization computer program entitled SANDOP. As a demonstration of its capabilities, SANDOP is used in the present study to design optimized composite sandwich cover panels for transp...

Traditional adaptive control lacks rigorous theoretical treatment for control in the presence of actuator saturation. Generally, adaptation is stopped as soon as the control saturates to avoid incorrect adaptation. Adaptation in the presence of saturation may be critical, especially when the controller is recovering from a failure. This paper presents an Adaptive Control methodology that facili...

Scab, caused by Cladosporium cucumerinum Ell. et Arthur, is a prevalent disease of cucumber (Cucumis sativus L.) worldwide. Scab can cause serious losses for cucumber production, especially in protected culture such as high tunnel production. Resistance to cucumber scab is dominant and is controlled by a single gene, Ccu. Breeding for resistant cultivars is the most efficient way to control the...

Image warping has many applications in art as well as in image processing. Usually, displacements are computed with mathematical functions or by transformations of a triangulation of control points. Here, di erent approaches based on scattered data interpolation methods are presented. These methods provide smooth deformations with easily controllable behavior. The usefulness and performance of ...

The Arctic soil organic carbon (SOC) pool is important but poorly defined. The most cited pool size estimates are based on one study that uses 48 North American soils of which only 5 are actually in the Arctic. Three of these 5 are in the colder high arctic not representative of soils across Arctic North America. Soil map-based pool estimates rely on subarctic soils to project the Arctic. In al...

In this paper we deal with stationary autoregressive processes of nite or in nite but unknown order. Under fairly general assumptions we derive the asymptotic consistency of a usual residual bootstrap procedure for smooth functions of the empirical autocovariance and autocorrelation. Especially the order of the tted autoregressive model is allowed to be data-dependent. Supplementary to the usua...

This thesis investigates the synthesis of controllers for time varying systems in order to satisfy an induced 2-norm closed loop performance bound. This performance criterion is a generalisation of the well known H1 norm criterion used in the frequency domain for analysis and synthesis of linear time invariant control systems. A number of di erent time varying system frameworks are considered, ...
