ANDRILL completed its first season in 2006-07 drilling AND-1B through the McMurdo Ice Shelf (MIS) to a depth of 1,285m below the sea floor, a record for Antarctic margin drilling, with 99% recovery. The alternating glacial-interglacial sediment packages interbedded with volcanics provide a uniquely detailed record of Antarctic glacial and climatic change through the Neogene. This paper summariz...

In [4] an algorithm is presented for analytic phase margin control design. Without special care, however, the compensator computed with this algorithm may not be a real rational function. The problem is evident when the plant has real unstable poles. In this case the algorithm in [4] requires a mapping of real points into complex values, and it is not clear that the resulting compensator has re...

In this document we give a short overview of the reasons why Rijndael should be selected as the AES. We have divided our arguments into four categories: • Security: Rijndael has the same objective security level as the other finalists, and can easily be implemented in a secure way. • Efficiency: Rijndael has a large "performance margin" compared to the other candidates. • Design philosophy: The...

1 The central problem in the case of face detectors is to build a face class model. We present a method for face class modeling in the eigenfaces space using a large-margin classifier like SVM. Two main issues are addressed: what is the required number of eigenfaces to achieve a good classification rate and how to train the SVM for a good generalization. As the experimental evidence show, gener...

Sauer’s Lemma is extended to classes HN of binary-valued functions h on [n] = {1, . . . , n} which have a margin less than or equal to N on all x ∈ [n] with h(x) = 1, where the margin μh(x) of h at x ∈ [n] is defined as the largest non-negative integer a such that h is constant on the interval Ia(x) = [x− a, x+ a] ⊆ [n]. Estimates are obtained for the cardinality of classes of binary valued fun...

introduction: this in vitro study evaluated the influence of composite thickness (with or without fiber reinforcement) on fracture resistance of direct restorations in endodontically treated teeth. methods and materials: fifty-six intact human premolars were chosen and randomly divided into four groups ( n =14). after preparation of a mesio-occluso-distal (mod) cavities and cusp reduction, the ...

Abstract A margin line, defined as the boundary curve of contact area between a prepared tooth and dental restoration, considerably influences end shape restoration design. Most studies that have extracted lines from mesh models representing teeth faced convergence problems in path search therefore pose inconvenience specifying multiple input points intermediate goal points. To overcome these p...

Background: In this study, it was aimed to use a finite element stress analysis method determine the amount of on enamel, dentin, restoration, resin cement and glass ionomer in amalgam class II disto-occlusal (DO) cavities by using two different cements with thicknesses amalgams Young’ s modulus values, respectively. Methods: A three-dimensional tooth model obtained scanning an extracted human ...

background: esthetic demands among patients have led to the introduction of tooth-colored restorations. composite resins bond to enamel applying acid etch technique. total etch adhesion systems are still considered as golden standard among bonding systems. however, clinicians have tendency towards using adhesive systems with a simplified application procedure. the aim of the present study is to...
