ORTHOMADS: A deterministic MADS instance with orthogonal directions ∗
, 2008
"... The purpose of this paper is to introduce a new way of choosing directions for the Mesh Adaptive Direct Search (MADS) class of algorithms. The advantages of this new ORTHOMADS instantiation of MADS are that the polling directions are chosen deterministically, ensuring that the results of a given run ..."

run are repeatable, and that they are orthogonal to each other, therefore the convex cones of missed directions at each iteration are minimal in size. The convergence results for ORTHOMADS follow directly from those already published for MADS, and they hold deterministically, rather than
YARN DIAMETER CHARACTERIZATION USING TWO ORTHOGONAL DIRECTIONS
"... T he most important parameters that are usedAQ1 to specify yarn quality are the linear density,structural features (e.g., twist, porosity), andfiber content. An example of a typical yarn configuration (Fig. 1a) shows that the yarn diameter is the distance between yarn contours and that irregularitie ..."

length (4 mm); thick places: an increase in the mass, and lasting more than 4 mm; neps: a huge amount of yarn mass (equal or greater than 100%) in a short length (typically from 1 to 4 mm).1–5 As Fig. 1 suggests, there is a direct relationship between the variation of yarn mass and the yarn’s diameter
NON-REDUNDANT, LINEAR-PHASE, SEMI-ORTHOGONAL, DIRECTIONAL COMPLEX WAVELETS
, 2004
"... The directionality and phase information provided by nonredundant complex wavelet transforms (NCWTs) provide significant potential benefits for image/video processing and compression applications. However, because existing NCWTs are created by downsampling filtered wavelet coefficients, the finest s ..."

scale of these transforms has resolution 4 × lower than the real input signal. In this paper, we propose a linear-phase, semi-orthogonal, directional NCWT design using a novel triband filter bank. At the finest scale, the resulting transform has resolution 3 × lower than the real input signal. We
Discriminant adaptive nearest neighbor classification,
, 1995
"... Abstract Nearest neighbor classification expects the class conditional probabilities to be locally constant, and suffers from bias in high dimensions We propose a locally adaptive form of nearest neighbor classification to try to finesse this curse of dimensionality. We use a local linear discrimin ..."

discriminant analysis to estimate an effective metric for computing neighborhoods. We determine the local decision boundaries from centroid information, and then shrink neighborhoods in directions orthogonal to these local decision boundaries, and elongate them parallel to the boundaries. Thereafter, any
Orthogonal Direct Sum Masking A Smartcard Friendly Computation Paradigm in a Code, with Builtin Protection against Side-Channel and Fault Attacks
"... Abstract. Secure elements, such as smartcards or trusted platform mod-ules (TPMs), must be protected against implementation-level attacks. Those include side-channel and fault injection attacks. We introduce ODSM, Orthogonal Direct Sum Masking, a new computation paradigm that achieves protection aga ..."

Discrete orthogonal polynomial ensembles and the Plancherel measure
, 2001
"... We consider discrete orthogonal polynomial ensembles which are discrete analogues of the orthogonal polynomial ensembles in random matrix theory. These ensembles occur in certain problems in combinatorial probability and can be thought of as probability measures on partitions. The Meixner ensemble i ..."

Digital step edges from zero crossing of second directional derivatives
- Pattern Analysis and Machine Intelligence, IEEE Transactions on
, 1984
"... Abstract-We use the facet model to accomplish step edge detection. The essence of the facet model is that any analysis made on the basis of the pixel values in some neighborhood has its final authoritative inter-pretation relative to the underlying gray tone intensity surface of which the neighborho ..."

Upon comparing the performance of this zero crossing of second di-rectional derivative operator with the Prewitt gradient operator and the Marr-Hildreth zero
Orthogonal Structures in Directed Graphs
"... this paper is to show how the concept of 1--weightings and the technique used by Frank can be used to obtain a similar theory for directed graphs. In the next section we develop the network flow method and show how this method can be used to obtain a sequence of orthogonal pairs in directed graphs. ..."
