background and aims. orientation of the occlusal plane is one of the most important clinical procedures in prosthodontic rehabilitation of edentulous patients. the aim of this study was to define the best posterior reference point of ala-tragus line for orientation of occlusal plane for complete denture fabrication. materials and methods. fifty-three dental students (27 females and 26 males) wi...

State-of-the-art methods of people counting in crowded scenes rely on deep networks to estimate people density in the image plane. Perspective distortion effects are handled implicitly by either learning scale-invariant features or estimating density in patches of different sizes, neither of which accounts for the fact that scale changes must be consistent over the whole scene. In this paper, w...

In this paper, we introduce a method of threshold secret sharing scheme (TSSS) in which secret reconstruction is based on Babai's nearest plane algorithm. In order to supply secure public channels for transmitting shares to parties, we need to ensure that there are no quantum threats to these channels. A solution to this problem can be utilization of lattice-based cryptosystems for these channe...

In this paper, we deal with the problem of generating all triangulations of plane graphs. We give an algorithm for generating all triangulations of a triconnected plane graph G of n vertices. Our algorithm establishes a tree structure among the triangulations of G, called the “tree of triangulations,” and generates each triangulation of G in O(1) time. The algorithm uses O(n) space and generate...

An iterative beam shaping algorithm is proposed to simultaneously shape the amplitude and phase of an optical beam. The proposed algorithm consists of one input plane and two completely overlapped output planes which refer to the output plane in real space. The two output planes are imposed with both amplitude and phase constraints, and the constrained areas in the two output planes are complem...

This paper proposes an efficient framework for deterministic service guarantees in slot-based optical networks. The framework uses the combination of a control plane and a data plane to solve the complex problem of capacity allocation, slot-matching and traffic scheduling. The control plane implements admission control and capacity allocation to source-destination node pairs and the data plane ...

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...

A efficient biped robot balance control is essential to achieve dynamic walk. In this work we propose a incremental fuzzy algorithm to control the lateral plane movements for a biped robot. This algorithm is computationally more economic as an adaptive control algorithm. This algorithm demonstrate a smooth balance control response and a correct interaction between the walking algorithm and the ...

We consider the problem of computing spanners of Euclidean and unit disk graphs embedded in the two-dimensional Euclidean plane. We are particularly interested in spanners that possess useful properties such as planarity, bounded degree, and/or light weight. Such spanners have been extensively studied in the area of computational geometry and have been used as the building block for constructin...
