In this paper, we introduce a new generalization of the well-known Fréchet distance between two polygonal curves, and provide an efficient algorithm for computing it. The classical Fréchet distance between two polygonal curves corresponds to the maximum distance between two point objects that traverse the curves with arbitrary non-negative speeds. Here, we consider a problem instance in which t...

In this paper, we introduce a pipe interface that recognizes touch on tone holes by the resonances in the pipe instead of a touch sensor. This work was based on the acoustic principles of woodwind instruments without complex sensors and electronic circuits to develop a simple and durable interface. The measured signals were analyzed to show that different fingerings generate various sounds. The...

OBJECTIVE/HYPOTHESIS The purpose of this paper is to introduce the rate of divergence as an objective measure to differentiate between the four voice types based on the amount of disorder present in a signal. We hypothesized that rate of divergence would provide an objective measure that can quantify all four voice types. STUDY DESIGN A total of 150 acoustic voice recordings were randomly sel...

We investigate the energy behavior of the diffraction cone in the exclusive vector meson production in diffractive DIS within the kt-factorization approach. In our calculations, we make full use of fits to the unintegrated gluon structure functions extracted recently from experimental data on F2p. Confirming early predictions, we observe that shrinkage of the diffraction cone due to the slope o...

The idea of applying map and filter functions on consecutive sublists instead of on individual list elements is discussed and developed in this paper. A non-empty, consecutive sublist is called a bite. Both map and filter functions accept a function parameter a bite function which is responsible for returning a prefix bite of a list. We develop families of bite functions via a collection of hig...

BACKGROUND Spatial global clustering tests can be used to evaluate the geographical distribution of health outcomes. The power of several of these tests has been evaluated and compared using simulated data, but their performance using real unadjusted data and data adjusted for individual- and area-level covariates has not been reported previously.We evaluated data on prostate cancer histologic ...

The contrast of any image is a very important characteristic by which the image can be judged as good or poor. In this paper, we introduce a simple approach for the process of image contrast enhancement using the sigmoid function in spatial domain. To achieve this simple contrast enhancement, a novel mask based on using the input value together with the sigmoid function formula in an equation t...

In a recent paper we described a method for assessing the accuracy of polygonal approximation algorithms [16]. Here we develop several measures to assess the stability of such approximation algorithms under variations in their scale parameters. A monotonicity index is introduced that can be applied to analyse the change in the approximation error or the number of line segments against increasin...

Multilinear maps serve as a basis for a wide range of cryptographic applications. The first candidate construction of multilinear maps was proposed by Garg, Gentry, and Halevi in 2013, and soon afterwards, another construction was suggested by Coron, Lepoint, and Tibouchi (CLT13), which works over the integers. However, both of these were found to be insecure in the face of so-called zeroizing ...

Robustness and speed are primary considerations when developing deformation methodologies for animatable mesh objects. The goal of this paper is to present such a robust and fast geometric mesh deformation algorithm. The algorithm is feature points based i.e. it can be applied to enable the animation of various mesh objects defined by the placement of their feature points. As a specific applica...
