Interpolation and L1-approximation by trigonometric polynomials and blending functions [PDF]

, 2012
We present results on interpolation and L1-approximation of periodic functions by trigonometric polynomials and trigonometric blending functions. In Section 1, we obtain an error-representation formula for Hermite–Lagrange interpolation by trigonometric ...

Area of origin analysis for expirated patterns using HemoVision

Journal of Forensic Sciences, EarlyView.
Abstract Although bloodstain pattern analysis (BPA) can be performed on various types of patterns, there is a lack of research looking into whether the area of origin (AO) can be determined for expirated patterns. Expirated patterns are formed when blood is pushed out of an opening in the body by the force of air, in some cases forming a pattern of ...

Inference on state occupancy in covariate‐driven hidden Markov models

Methods in Ecology and Evolution, EarlyView.
Abstract Hidden Markov models (HMMs) are natural and popular tools for analysing animal behaviour based on movement, acceleration and other sensor data. In particular, these models make it possible to infer how the animal's decision‐making process interacts with internal and external drivers by relating the probabilities of switching between distinct ...

On the p-Version of the Schwab-Borchardt Mean

International Journal of Mathematics and Mathematical Sciences, 2014
This paper deals with a one-parameter generalization of the Schwab-Borchardt mean. The new mean is defined in terms of the inverse functions of the generalized trigonometric and generalized hyperbolic functions.

Trends in new psychoactive substance poisonings in the Netherlands: A 14‐year retrospective analysis (2012–2025)

Addiction, EarlyView.
Abstract Background and aims Data on the presence of new psychoactive substances (NPS) mainly originate from drug‐checking, law enforcement and wastewater analysis sources, while data on NPS poisonings are scarce. In Europe, the documented incidence rate of NPS poisonings is highest in the Netherlands.

Trigonometric functions - every time different [PDF]

This bachelor’s thesis deals with the description of various generalizations or extensions of trigonometric functions. For each type of these functions, definitions and basic properties are provided, which are then compared with the properties of ...

Review on Distributions Generated Using Trigonometric Functions

Austrian Journal of Statistics
In the present scenario, researchers are interested in developing new distributions based on trigonometric functions to model data.  Previously, data modelling was commonly done with standard and existing distribution functions.

Interpolated Adaptive Linear Reduced Order Modeling for Deformation Dynamics

Computer Graphics Forum, EarlyView.
Abstract Linear reduced‐order modeling (ROM) is widely used for efficient simulation of deformation dynamics, but its accuracy is often limited by the fixed linearization of the reduced mapping. We propose a new adaptive strategy for linear ROM that allows the reduced mapping to vary dynamically in response to the evolving deformation state ...

A Method For Approximating Univariate Convex Functions Using Only Function Value Evaluations [PDF]

In this paper, piecewise linear upper and lower bounds for univariate convex functions are derived that are only based on function value information. These upper and lower bounds can be used to approximate univariate convex functions.
