Coherent multiple-antenna block-fading channels at finite blocklength

, 2018
In this paper we consider a channel model that is often used to describe the mobile wireless scenario: multiple-antenna additive white Gaussian noise channels subject to random (fading) gain with full channel state information at the receiver.

The Combined Effect of Gas Phase and Condensed Phase Mechanisms in Flame Retardancy of Polybutylene Succinate

Journal of Vinyl and Additive Technology, EarlyView.
A combination of DOPO and APP flame‐retardants results in a V‐0 UL 94 rating. ABSTRACT In this study, we addressed the challenge of eliminating, during combustion, the flaming dripping behavior of polybutylene succinate flame retarded with ammonium polyphosphate, a key barrier to achieving a V‐0 rating in the UL 94 flammability test without excessive ...

Density‐Valued ARMA Models by Spline Mixtures

Journal of Time Series Analysis, EarlyView.
ABSTRACT This paper proposes a novel framework for modeling time series of probability density functions by extending autoregressive moving average (ARMA) models to density‐valued data. The method is based on a transformation approach, wherein each density function on a compact domain [0,1]d$$ {\left[0,1\right]}^d $$ is approximated by a B‐spline ...
