Specific Heat of Selected Legumes and Cereal Grains Grown in North Eastern Nigeria
Arid Zone Journal of Engineering, Technology and Environment, 2012 Thermal properties of agricultural materials are important parameters in the design and operation of thermal processing machines. This study focuses on the determination of specific heat of some staple crops at different moisture contents and ...

Use of cryogenic buoyancy systems for controlled removal of heavy objects from the seabed
, 2009 The concept design of a lightweight cryogenic marine heavy lift buoyancy system has been investigated. The approach makes use of a novel cryogenic system for provision of buoyancy within the ocean environment. The objective is to be able to lift or lower

Energy Science &Engineering, EarlyView.This study investigates the heat transfer characteristics of copper‐foam composite phase change materials with different gradient porosities. Three models with uniform porosity and three models with gradient porosities are developed to examine their effects on temperature distribution and melting behavior. ABSTRACT Phase change materials (PCMs) exhibit

A Krasznokvajdai mikrotérség lakosságának közlekedési szokásai
Tér és Társadalom, 2009 Hazánk periférikus térségeiben a rendszerváltozást megelőző évtizedekben – ha meglehetősen szerény mértékben is –, de elfogadhatóak voltak az életkörülmények, és nem voltak kirívóan nagy területi különbségek.

Equivariant formality of istropy actions
, 2018 Let $G$ be a compact connected Lie group and $K$ a connected Lie subgroup. In this paper, we collect an assortment of results on equivariant formality of the isotropy action of $K$ on $G/K$ and thus improving those from previous work. We show that if the

Energy Science &Engineering, EarlyView.A deep reinforcement learning–based control architecture is proposed to coordinate heat pumps, thermal storage, renewable energy, and demand response in data center waste heat recovery systems. The agent learns optimal control actions from system states and reward feedback to achieve electrical–thermal co‐optimization under realistic operational ...
