Determination of Spatial-Temporal Correlation Structure of Troposphere Ozone Data in Tehran City [PDF]
Journal of Sciences, Islamic Republic of Iran, 2013 Spatial-temporal modeling of air pollutants, ground-level ozone concentrations in particular, has attracted recent attention because by using spatial-temporal modeling, can analyze, interpolate or predict ozone levels at any location.

Parametric Continuity of Stationary Distributions [PDF]
The paper gives conditions under which stationary distributions of Markov models depend continuously on the parameters. It extends a well-known parametric continuity theorem for compact state space to the unbounded setting of standard econometrics and ...

Perfection and Stability of Stationary Points with Applications in Noncooperative Games [PDF]
It is well known that an upper semi-continuous compact- and convex-valued mapping ö from a nonempty compact and convex set X to the Euclidean space of which X is a subset has at least one stationary point, being a point in X at which the image ö (x)has a

Journal of Applied Science and EngineeringThis paper recovers stationary optical solitons for the perturbed Radhakrishnan–Kundu–Lakshmanan equation with nonlinear chromatic dispersion. There are eight approaches that have been implemented to recover these solitons. A full spectrum of solitons is

LS2W: Implementing the Locally Stationary 2D Wavelet Process Approach in R [PDF]
Locally stationary process representations have recently been proposed and applied to both time series and image analysis applications. This article describes an implementation of the locally stationary two-dimensional wavelet process approach in R. This

Advanced Materials, EarlyView.Memristors offer tunable resistance and intrinsic instability, making them promising tunable noise sources. We propose a spiking‐rate‐programmable probabilistic neuron using a Ru/TaOx/Pt memristor, where resistance‐dependent noise enables frequency‐selective encoding.

A Study on the Air Spring Suspension Morphologies of EMUs Bogie
机车电传动, 2013 Based on the pneumatic model of air spring and the dynamics MBS model of EMUs, the dynamics behaviors of EMUs in the2-point configuration and 4-point configuration were studied contrastively. What’s more, two improved suspension morphologies wereanalyzed,

Fitting dynamic factor models to non-stationary time series [PDF]
Factor modelling of a large time series panel has widely proven useful to reduce its cross-sectional dimensionality. This is done by explaining common co-movements in the panel through the existence of a small number of common components, up to some ...
