energy and environmental analysis

Published on 2026-06-10 by @OXFORD

Abstract: AbstractThe urgent need to phase out R134a, due to its significant global warming potential (GWP), has accelerated the search for sustainable alternatives in refrigeration systems. This study presents a comprehensive experimental investigation of R600a and R1234yf as low-GWP retrofit alternatives to R134a in a domestic refrigerator. Performance was assessed for both a 24-hour steady-state analysis and representative 150-minute dynamic operating profiles at a setpoint of +4°C. The results indica[...]


Our summary: This study investigates R600a and R1234yf as alternatives to R134a in refrigeration. R600a proved to be more energy-efficient and environmentally sustainable than R1234yf. The findings highlight the importance of considering energy efficiency alongside low GWP in evaluating refrigerants environmental impact.

Carbon dioxide emissions elimination for reverse osmosis desalination units of remote islands via photovoltaic and battery solution. The case of Karpathos Island

Published on 2026-06-06 by @OXFORD

Abstract: AbstractRecently, the imperative water demand problem of small islands in the South-East Mediterranean area is being faced with the development and operation of new reverse osmosis (RO) desalination plants at high operational and environmental cost. One of the most serious RO desalination unit’s problems is their high-energy demand. This water demand coincides with the electricity demand, both peaked during the summer imposing the existing local electrical power stations to operate near their [...]


Our summary: This study explores the integration of photovoltaic systems and battery storage to power reverse osmosis desalination units on Karpathos Island. It addresses high energy demands and carbon emissions associated with traditional diesel power. The proposed solution aims to enhance clean energy autonomy while minimizing operational costs and environmental impact.

Optimizing strategic equity cooperation for low-carbon supply chain integration under cap-and-trade regulation

Published on 2026-06-05 by @OXFORD

Abstract: AbstractDriven by intensifying global concerns regarding climate change, cap-and-trade regulations have been widely implemented to catalyze low-carbon economic transitions. Through equity cooperation, supply chain entities can mitigate double marginalization effects and enhance sustainable development. This study evaluates the impact of complete centralization (SC), decentralization (DC), and three partial-centralization models, specifically downstream-shareholding (DS), upstream-shareholding (U[...]


Our summary: This study analyzes the effects of different equity cooperation models on carbon reduction and green advertising strategies within supply chains under cap-and-trade regulations. It finds that carbon reduction rates are positively influenced by carbon trading prices, but excessive costs can hinder efforts. Additionally, the US model of equity distribution maximizes supply chain profits when both retailer and manufacturer hold significant equity stakes.

Performance analysis of a coal mine air supply system based on a multienergy complementary energy supply system

Published on 2026-06-03 by @OXFORD

Abstract: AbstractMine ventilation air heating in severely cold regions is commonly supplied by coal-fired boilers, leading to high energy use and environmental impacts. This study proposes a multienergy complementary energy supply system integrating air-source heat pumps (ASHPs), a cascade water-source heat pump, and thermal energy storage to ensure reliable shaft anti-freezing (3°C) and flexible operation under time-of-use electricity pricing. A dynamic TRNSYS model was developed for a coal mine in Wuh[...]


Our summary: This study presents a multienergy complementary energy supply system for mine ventilation heating in cold regions. A dynamic TRNSYS model was validated, showing a 7.57% error margin. The proposed system enhances performance in extreme cold, reducing costs and emissions significantly.

Method and apparatus for denoising ray tracing image

Patent published on the 2026-05-28 in US under Ref US20260148351 by SAMSUNG ELECTRONICS CO LTD [KR] (Kang Nahyup [kr], Kim Hanjun [kr], Jang Seokhwan [kr], Jung Hwiryong [kr], Hong Seokpyo [kr])

Abstract: A method of denoising a ray tracing image includes obtaining an irradiance image by receiving a rendering result, by separating the irradiance image for each frequency component, performing downsampling on the separated irradiance image to to obtain a first downsampled irradiance image and a second downsampled irradiance image, obtaining a filter weight using a denoising look-up table (LUT) based on pixel information, the first downsampled irradiance image and the second downsampled irradiance i[...]


Our summary: The method involves obtaining an irradiance image from a rendering result and separating it into frequency components. It then performs downsampling and uses a denoising look-up table to obtain filter weights for a weighted sum. Finally, it upscales the denoised image and combines it with an albedo image to produce the final output.
