Exergy Efficiency of Interplanetary Transfer Vehicles [PDF]
, 2019 In order to optimize systems, systems engineers require some sort of measure with which to compare vastly different system components. One such measure is system exergy, or the usable system work. Exergy balance analysis models provide a comparison of different system configurations, allowing systems engineers to compare different systems configuration

Long Term Trends in Resource Exergy Consumption and Useful Work Supplies in the UK, 1900-2000 [PDF]
Our aim is to explain historical economic growth in the UK economy by introducing an empirical measure for useful work derived from natural resource energy inputs into an augmented production function.

International Transactions in Operational Research, Volume 33, Issue 4, Page 2499-2534, July 2026.Abstract This paper presents a two‐stage model for planning a renewable energy portfolio by balancing economic, social and environmental sustainability goals. The first stage addresses a multi‐objective problem where conflictive impacts generated by the energy portfolios should be optimised according to the corresponding economic, social or ...

Analysis of the Behaviour of Biofuel-Fired Gas Turbine Power Plants [PDF]
, 2011 The utilisation of biofuels in gas turbines is a promising alternative to fossil fuels for power generation. It would lead to significant reduction of CO2 emissions using an existing combustion technology, although significant changes seem to be needed

A Comprehensive Review of Waste‐Derived Materials for Solar Still Performance Enhancement
Advanced Materials Interfaces, Volume 13, Issue 9, 5 May 2026.Solar desalination reduces energy use and produces freshwater sustainably, but its productivity is limited and cannot meet rising demand. Thus, solar desalination system improvements are sought to boost water productivity. Waste materials are abundantly available and burden the environment, making them low‐cost enhancers for solar desalination systems.

Exergy Analysis of Frost-free Air-source Heat Pump System
Zhileng xuebao, 2020 This study proposes a "one tower with three functions" solution for a dehumidification type frost-free air-source heat pump (ASHP) system, which can not only solve the frost problem of traditional ASHP systems in winter, but also improve the performance ...

Journal of Food Science, Volume 91, Issue 5, May 2026.ABSTRACT The present study aimed to evaluate the quality and nutritional properties of guava slices dried in a greenhouse solar dryer (operated under mixed and direct modes) and an electric stove at 50°C. The results showed that mixed‐mode solar drying resulted in greater retention of vitamin C (112.60 mg/100 g), carotenoids (0.37 mg/g), and ...
