DETERMINATION OF THERMAL CONDUCTIVITY OF MOIST RIGID POLYMER FOAMS

Determination of thermal conductivity of moist rigid polymer foams

A geometric model of the polymer foam structure was verified taking into account the moisture content of the material and the degree of wetness of the pore surface.Mathematical relations were developed to determine the moisture value at which transition from partial to full wetting of the pore surface occurs and vice versa.A mathematical descriptio

Long-term behavior of the Kelvin waves revealed by CHAMP/GPS RO measurements and their effects on the tropopause structure

The vertical and temporal variations of Kelvin waves and swisse high strength magnesium powder berry the associated effects on the tropical tropopause were studied using long-term (from May 2001 to October 2005) CHAMP/GPS (CHAllenging Mini satellite Payload/Global Positioning System) radio occultation (RO) measurements.The periods of these wav

Asymptotic Optimality and Rates of Convergence of Quantized Stationary Policies in Continuous-Time Markov Decision Processes

This paper is concerned with the asymptotic optimality of quantized stationary policies for continuous-time Markov decision processes (CTMDPs) in Polish spaces with state-dependent discount factors, where the transition rates and reward rates are allowed to be unbounded.Using the dynamic programming approach, we first establish the discounted optim
