Smoothing Newton method for NCP with the identification of degenerate indices

Journal of Computational and Applied Mathematics, 2010
A new smoothing Gauss-Newton method for nonlinear complementarity prolems (NCP) by using a NPC-function for reformulation of the original problem. The method, based on active-set strategy, contains an estimating technique for the determination of the degenerate set of indices at the solution \(x^*\) under suitable regularity conditions.

Spatial and temporal regularization to estimate COVID-19 reproduction number R(t): Promoting piecewise smoothness via convex optimization

medRxiv, 2020
Among the different indicators that quantify the spread of an epidemic, such as the on-going COVID-19, stands first the reproduction number which measures how many people can be contaminated by an infected person.

Rethinking ecosystem service indicators for their application to intermittent rivers [PDF]

, 2022
In these times of strong pressure on aquatic ecosystems and water resources due to climate change and water abstraction, intermittent rivers and ephemeral streams (IRES) (rivers that periodically cease to flow and/or dry) have become valuable assets ...

An improved third-order HWCNS scheme based on the multi-order candidates (MOC) weighting framework

Kongqi donglixue xuebao
To mitigate the order reduction of traditional third-order Z-type nonlinear weighted interpolation, a theoretical analysis method based on Taylor expansion is proposed for the order-of-magnitude relationships of smoothness indicators near critical points.

An efficient method for smoothing indicator-dilution and other unimodal curves [PDF]

Computers and Biomedical Research, 1988
A mathematical function has been developed for approximating unimodal functions, particularly those which are non-Gaussian, skewed, and incomplete. It is useful as an alternative to cubic splines in smoothing noisy experimental data. Particular applications are to indicator-dilution curves and probability density functions of varied form.

Research on curve smoothing algorithm for diesel indicator diagram [PDF]

Vibroengineering Procedia, 2020
The algorithm of curve smoothing for diesel indicator diagram is introduced, and the concrete implementation process is expounded in detail. First, the multi cyclic mean value operation of indicator diagram data is performed. By probable error of calculating indicator diagram data, if probable error is greater than a specific value, and the predicted ...

Analyzing the Service Quality of E-Trike Operations: A New Sustainable Transportation Infrastructure in Metro Manila, Philippines

Infrastructures, 2022
The electric tricycle, often known as an e-trike, is a three-wheeled electric vehicle designed to transport a small group of people over short distances on side streets. This study aims to develop a service quality model of sustainable e-trike operations
