hp-Version discontinuous Galerkin methods with interior penalty for partial differential equations with nonnegative characteristic form. [PDF]

, 2002
In this paper we consider the a posteriori and a priori analysis of hp-discontinuous Galerkin interior penalty methods for second-order partial differential equations with nonnegative characteristic form. In particular, we discuss the question of error

Some issues concerning Large-Eddy Simulation of inertial particle dispersion in turbulent bounded flows

, 2008
The problem of an accurate Eulerian-Lagrangian modeling of inertial particle dispersion in Large Eddy Simulation (LES) of turbulent wall-bounded flows is addressed.

Variance Matrix Priors for Dirichlet Process Mixture Models With Gaussian Kernels

International Statistical Review, EarlyView.
Summary Bayesian mixture modelling is widely used for density estimation and clustering. The Dirichlet process mixture model (DPMM) is the most popular Bayesian non‐parametric mixture modelling approach. In this manuscript, we study the choice of prior for the variance or precision matrix when Gaussian kernels are adopted.

A Class of Spectral Element Methods and Its A Priori/A Posteriori Error Estimates for 2nd-Order Elliptic Eigenvalue Problems

Abstract and Applied Analysis, 2013
This paper discusses spectral and spectral element methods with Legendre-Gauss-Lobatto nodal basis for general 2nd-order elliptic eigenvalue problems. The special work of this paper is as follows.

A Non‐Parametric Framework for Correlation Functions on Product Metric Spaces

International Statistical Review, EarlyView.
Summary We propose a non‐parametric framework for analysing data defined over products of metric spaces, a versatile class encountered in various fields. This framework accommodates non‐stationarity and seasonality and is applicable to both local and global domains, such as the Earth's surface, as well as domains evolving over linear time or time ...

A Priori and A Posteriori Machine Learning and Nonlinear Artificial Neural Networks [PDF]

, 2010
The main idea of a priori machine learning is to apply a machine learning method on a machine learning problem itself. We call it "a priori" because the processed data set does not originate from any measurement or other observation. Machine learning which deals with any observation is called "posterior".

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

KANT'IN BİLGİ KURAMI VE SENTETİK ÖNERMELER

Felsefe Dünyası, 2003
According to Kant, while one part of our knowledge relies on both senses and thought, the other part relies on thought only. Knowledge of phenomena within a space and time come through both senses and thought, whereas knowledge of non-phenomenal ideas ...

Imaging malaria parasites across scales and time

Journal of Microscopy, EarlyView.
Abstract The idea that disease is caused at the cellular level is so fundamental to us that we might forget the critical role microscopy played in generating and developing this insight. Visually identifying diseased or infected cells lays the foundation for any effort to curb human pathology.
