Optimization analysis of solar-powered average temperature Stirling heat engine

open access: yesJournal of Energy in Southern Africa, 2017
This paper investigates the performance of the solar powered dish-Stirling engine using the nonlinearized heat loss model of the solar dish collector and the irreversible cycle model of the Stirling engine.

Churchill and Germany: A ‘Special’ Relationship

open access: yesHistory, EarlyView.
Abstract No other country defined the trajectory of Churchill's political career more than Germany, a country of which he had little direct knowledge but which he either sought to emulate, accommodate or oppose throughout his time in politics. This article traces Churchill's relationship with Germany from his entry into politics at the beginning of the

The Power and Efficiency Analyses of the Cylindrical Cavity Receiver on the Solar Stirling Engine

open access: yesEnergies, 2020
The technique of solar dish and Stirling engine combination is the most challenging and promising one. For the efficient conversion of the externally concentrated heat to the usable power, we studied the influences of the wall temperature, inclination ...

Proteomic and Transcriptomic Signatures of Poor Asthma Symptom Control in the U‐BIOPRED Cohort

open access: yesAllergy, EarlyView.
No stable features were identified as associated with asthma symptom control in transcriptomics or sputum proteomics. Higher TWEAKR/TNFRSF12A and MBL/MBP‐C serum levels increased the odds of uncontrolled symptoms, while higher MK08/MAPK8 and CD5L serum levels decreased the odds, after adjustment for clinical variables.

Stirling Engine Configuration Selection [PDF]

open access: yesEnergies, 2018
Unlike internal combustion engines, Stirling engines can be designed to work with many drive mechanisms based on the three primary configurations, alpha, beta and gamma. Hundreds of different combinations of configuration and mechanical drives have been proposed. Few succeed beyond prototypes.

Analysis of Stirling engine’s performance in recovering waste heat from wood pellet, coconut husk and bagasse

open access: yesJournal of Thermal Science and Technology
In recent years, industrial boilers that generate power from biomass have drawn a lot of attention. Nevertheless, a sizable portion of thermal energy is frequently lost to the environment as flue gas throughout the process.

Expert Memories: The Professional Construction of the Past and the Mnemonic Making of Occupations

open access: yesJournal of Management Studies, EarlyView.
Abstract This article introduces the special issue on occupations and memory in organizations. To foster increasing collaboration from scholars from both fields, we offer a general argument connecting memory and occupations on two levels. At the societal level, we show how memory experts, such as historians, archivists, and museologists, have played a ...

Thermal analysis of Stirling engine solar driven

open access: yesRevue des Énergies Renouvelables, 2008
Solar energy is one of the more attractive renewable energy sources; the conversion of the latter per thermal way into electricity is a major energy stake.

Time‐Varying Dispersion Integer‐Valued GARCH Models

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT We introduce a general class of INteger‐valued Generalized AutoRegressive Conditionally Heteroscedastic (INGARCH) processes by allowing simultaneously time‐varying mean and dispersion parameters. We call such models time‐varying dispersion INGARCH (tv‐DINGARCH) models.
