In the previous determination [Finn & Musti (1950 ▶). J. Soc. Chem. Ind. (London), 69, S849] of the title compound, C(13)H(12)O(2), the three-dimensional coordinates and displacement parameters were not reported. This redetermination at room temperature reveals that the dihedral angle between the benzene rings is 79.73 (6)°. In the crystal, inter-molecular O-H⋯O hydrogen bonds between adjacent ...

Real-time performance is a very important goal for embedded speech recognition systems, where the evaluation of likelihoods for Gaussian mixture models (GMM) usually dominates the computation of a continuous density hidden Markov model (CDHMM) based system. The Bucket Box Intersection (BBI) algorithm is an optimization technique that uses a K-Dimensional binary tree to speed up the score comput...

--In this paper, we present region-based coding of medical images using integer wavelet transforms and the modified SPMT algorithm. Our method differs from previously reported region-ofinterest (ROI) coders in such a way that the regionbased integer wavelet transform is used to obtain the representation of the partitioned image plane rather than differentiating the coefficients associated with ...

Motivated by the concerns of theorem-proving, we generalise the notion of proof tree to that of hierarchical proof tree. Hierarchical trees extend ordinary trees by adding partial order structure to the set of nodes: that allows us to visualise a node as a rectangle in the plane rather than as a point, letting us use the containment relation to express structure additional to that given by a tr...

---~Y(z) = ~(Y(z)), which is non linear and autonomous. Singularity analysis applied to the intervening generating functions then permits to analyze asymptotically a number of parameters of the trees, like: root degree, number of leaves, path length, and level of nodes. In this way it is found that various models share common features: path length is O(n log n), the distribution of node levels ...

This paper has provided the first set of quantitative data of diffuse erythemal UV and UVA in tree shade at a sub-tropical Southern Hemisphere latitude. Over the summer, approximately 60% of the erythemal UV radiation in the tree shade is due to the diffuse component. Similarly, approximately 56% of the UVA radiation in the tree shade is due to the diffuse component. In the tree shade these dif...

A rectilinear Steiner tree for a set T of points in the plane is a tree which connects T using horizontal and vertical lines, In the Rectilinear Steiner Tree problem, input is a set T of n points in the Euclidean plane (R) and the goal is to find an rectilinear Steiner tree for T of smallest possible total length. A rectilinear Steiner arborecence for a set T of points and root r ∈ T is a recti...

The fraction and the distribution of the personal daily solar erythemal UV exposure were assessed for the shade provided by Australian gum trees in each of the four seasons to allow evaluation of the reduction in the personal UV exposure in tree shade over a year. The personal annual erythemal UV exposures in the tree shade ranged from 2,510 SED (Standard Erythema Dose) for the vertical part of...

Ž . A Steiner minimum tree SMT in the rectilinear plane is the shortest length tree interconnecting a set of points, called the regular points, possibly using Ž . additional vertices. A k-size Steiner minimum tree kSMT is one that can be split into components where all regular points are leaves and all components have at most k leaves. The k-Steiner ratio in the rectilinear plane, r , is the in...
