Using photovoltaic panels as alternative energy further cut carbon emissions by 50 %. The cost analysis showed that the combined technology was the most cost-effective extraction method.

Application of indoor thermal energy cycle and visual communication simulation scene based on Machine vision and optical image enhancement

Traditional thermal analysis methods have limitations in complex environments, and innovative technologies are urgently needed to improve the accuracy of indoor thermal monitoring and optimization. In this paper, machine vision and optical image enhancement technology are combined to simulate the indoor heat energy cycle process to achieve more efficient heat management and visual communication, so as to improve the energy utilization efficiency and residential comfort of buildings. In this paper, a high-resolution camera is used to capture real-time images of indoor environment, image quality is enhanced by image processing algorithm, and heat distribution characteristics are extracted. The machine learning model is used to analyze the dynamic changes of the thermal energy cycle, and the visual model of the indoor thermal energy cycle is constructed by combining the fluid dynamics theory. The experimental results show that the proposed method can effectively identify and display the key areas of indoor heat circulation and their changing trends. The simulation results show that the optical enhanced images can show different temperature regions more clearly, directly reflect the heat flow situation, and have a high agreement with the actual measurement data. Therefore, the indoor thermal energy cycle simulation method based on machine vision and optical image enhancement not only improves the accuracy and real-time performance of thermal energy analysis, but also provides visual support for indoor environmental management.

Wastewater treatment plants circular performance models evaluation: Portugal case-study

Population growth, economic growth, and changes in societal habits have led to significant changes in resource consumption. Therefore, it's crucial to accelerate the “reduce, reuse, recycle, and recover” of resources to ensure the balance of ecosystems, and water is surely one of the most fundamental resources. The acceleration of this approach in the water cycle makes sense only if we combine a circular economy (CE) transition with a sustainable perspective. In this context, more rational usage of water resources (which are under pressure) and more sustainable wastewater practices are expected to be a way towards the CE in the water and wastewater sector. This study provides a description and evaluation of existing frameworks that can be used to measure and assess the level of circularity of the wastewater treatment plant (WWTP). The treatment of urban wastewater requires new concepts of management and operation for the adaptation of existing plants, which lack robustness and flexibility, to face these new challenges and requirements because we can no longer continue to look at the WWTP only as treatment units, but as wastewater resource recovery facilities. This transformation must be transposed according to a matrix that allows the assessment to describe the current situation, analyse the problem, identify vulnerabilities and opportunities, identify, and evaluate measures, and identify and evaluate strategies. Considering that decision-makers face profound uncertainties such as climate change, population growth, population needs, innovative technologies, economic developments, ecosystem preservation and the impacts of human and natural activities.

MATERIALS AND METHODS: The study was conducted in three phases, following the user-centered design model, at the urology clinic of Khorshid Hospital (Isfahan, Iran) in 2021. Components and functionalities for BCM App were specified in three focus group sessions with urologists and urology residents using clinical guidelines. Adopting the Delphi technique, the participants completed a questionnaire addressing issues including educating and informing clinicians, performing clinical calculations, representing graphical information, and recording patient information. A conceptual model for the app was designed, and the final product was developed. The usability of the BCM App was evaluated using the think-aloud technique by usability experts and end-users. RESULTS: The app’s components were categorized into three groups: Patient evaluation, disease staging and management, and patient follow-up. The app’s main components included “bladder cancer classification,” “disease grading and staging,” “management based on the disease stages,” “principles of intravesical treatment,” and “classifying follow-ups by disease stages.” Moreover, the most prominent app’s functionalities were “using staging and grading table,” “using American Urological Association risk stratification,” “calculating disease stages,” “calculating patient’s follow-up,” and “recording patient information.” The usability evaluation results revealed that the BCM App was at a “highly acceptable” level. CONCLUSION: To design and develop a smartphone app for managing bladder cancer, the involvement of urologists is crucial. Apart from assisting urologists in effectively managing bladder cancer, the proposed app has the potential to enhance residents’ knowledge and streamline their access to evidence.

Features of organic agriculture development in Asian countries

Abstract The implementation of Sustainable Development Goals stimulates the use of new innovative technologies in production processes of the most resource-intensive types of economic activity in most countries of the world. The modern agricultural sector, which uses land and water resources to ensure food security in countries, aims to preserve soil fertility, the quality of water resources, air and biodiversity. That is why organic agriculture is gaining popularity not only in developed, but also in lower-income countries, including Asian countries. In recent years, countries such as China and India have increased the production of various types of products several times; moreover, their consumption is constantly increasing, which is the basis for achieving the goal of preserving the health of the nation. The study is aimed at identifying natural and economic factors in the development of production, consumption and export of organic products; existing risks. The choice of the object of study is due to the fact that China, India and Indonesia are the leading countries, among the top ten countries in terms of population, these countries are large in extent, in other words, the size of their territory allows them to produce various types of agricultural products; Vietnam and Thailand were chosen due to the fact that the countries are quite unique in terms of climatic conditions, which is why they produce unique types of products and have been actively increasing the production of organic products in recent years. Based on the methods of structural and comparative analysis, aligning time series, stable trends towards an increase in export volumes were identified, and the reasons for the increase in the production of organic products were substantiated.

Optical Coherence Tomography Split-Spectrum Amplitude-Decorrelation Optoretinography Detects Early Central Cone Photoreceptor Dysfunction in Retinal Dystrophies.

To investigate if split-spectrum amplitude-decorrelation optoretinography (SSADOR) can detect and measure macular cone dysfunction in inherited retinal dystrophies (IRDs). This study was a case series of participants presenting with various IRD pathologies. Participants were recruited from the Ophthalmic Genetics clinic at the Casey Eye Institute from February to August 2023. Multimodal and SSADOR imaging was obtained in all cases. We recruited nine participants, including four with macular dystrophy, one with fundus flavimaculatus, one with cone dystrophy, and three with retinitis pigmentosa. SSADOR decorrelation maps identified areas of cone functional impairment consistent with disease phenotypes. A correlation between the SSADOR signal and retinal sensitivity measured by microperimetry within the central 20° diameter area was observed. Additionally, SSADOR was able to demonstrate a decreased signal in mild cases when microperimetry measurements were still normal but subtle changes were also apparent on structural OCT. SSADOR is sensitive at detecting functional changes in macular cones, even prior to abnormalities in perimetry testing. We highlight the potential benefits of this innovative technology for the early detection of cone dysfunction and their potential contributions to earlier diagnosis and more accurate monitoring of progression. SSADOR is an innovative technology that detects early macular cone function changes, allowing for early diagnosis and precise monitoring of cone dysfunction progression. By serving as a potential clinical trial endpoint, SSADOR facilitates the translation of scientific findings into practical applications, ultimately improving patient care and outcomes.

IMPROVING ROAD SAFETY AT ACCIDENT-PRONE AREAS: A COMPARISON BETWEEN GLOW-IN-THE-DARK AND CONVENTIONAL ROAD MARKING

Driving at night is challenging due to poor vision, poor road visual guidance, and the need to encounter bright light sources. Factors like lack of street lighting, fading, and lack of reflectivity by road studs and retro-reflective materials affect road users' vision at night. Commentators have pointed out there is a critical demand to improve road safety in preventing road accidents and hazards that caused by the poor visibility of road markings and inadequacy lighting. Although road safety management has been given an important focus by the Ministry of Transportation Malaysia to achieve 50% reduction of road accidents by 2030, there is a critical demand to improve the present road markings method to overcome the issues of poor visibility or unclear road markings and inadequacy lighting that may trigger potential hazards to road users at night, with a new innovative road marking technology. Therefore, this paper is prepared with the objective to present the outcome of comparative study between the present conventional road markings and the newly innovative technology of glow-in-the-dark method with specific reference to the road safety management in Malaysia. This study employed a questionnaire survey to interview fifty-one (51) respondents that have experience of driving at night, with the objectives to get their opinions on present condition of road markings in Malaysia, and how the newly innovative technology glow-in-the-dark can improve road safety in Malaysia. The study outcome revealed that the glow-in-the-dark is deemed appropriate to enhance the visibility during low-light conditions as compared to the present conventional road markings. Although the initial cost is higher, the economic advantages of glow-in-the-dark in reducing the streetlight usage, lower electrical costs, and substantially extended lifespan have made this newly innovative road marking outweighed the downsides and economically wise choice to revolutionize road safety management practice at the accident-prone areas in Malaysia for achieving the SDG 3: Good Health and Well-being.

Synergistic charge-transfer dynamics of novel benzothiadiazole-based donor materials for higher power conversion efficiency: From structural engineering to efficiency assessment in non-fullerene organic solar cells

In the realm of organic solar cell technology, current research is dedicated to enhancing the photovoltaic properties of donor-π-acceptor (D-π-A) materials to achieve higher power conversion efficiencies (PCE). This optimization focuses particularly on fine-tuning the conduction band and electrolytic characteristics to maximize performance. Addressing the growing demand for novel materials with enhanced optoelectronic properties in organic photovoltaic research, our proposed compound BT05, one of nine new benzothiadiazole-based D-π-A donor molecules (BT01-BT09), exhibits a power conversion efficiency (PCE) of 25%, surpassing the 18% PCE of the reference compound BTD-OMe. TD-DFT and DFT simulations illuminate how donor modifications enhance the photovoltaic characteristics of the proposed molecules. Higher open-circuit voltage (VOC) of 1.74-2.26 V, increase in binding energy (∼1.997), λmax (470-476 nm), reduction in energy gap (4.25-4.65 eV), also validates the PCE results and confirm the usefulness of designed molecules (BT01-BT09). Moreover, DHOMO and ALUMO, TDM, reorganization energy λe (0.0124-0.0134) and λh (0.0094-0.0098), and NPA results also confirm that BT01-BT09 molecules unlock the organic solar cell's potential and advance sustainable energy solutions through innovative technology. Among all developed compounds, BT05 displays higher VOC (2.26 V), 87% fill-factor, and 25% PCE; hence, it is recommended in future solar cell applications.

Text2shape: Intelligent computational design of car outer contour shapes based on improved conditional Wasserstein generative adversarial network

To provide technical support for the initial design of products, we propose an innovative text2shape-based technology for intelligent computational design, which can map engineering semantics to functional/structural/Kansei feature spaces to generate product shapes. New energy vehicles were selected as the application object of this technology, as there are many creative ideas for the outer contour design of new energy vehicles. Firstly, a dataset with 2900 + samples was built based on feature engineering (FE) and Kansei engineering (KE). Each sample contains the car’s outer contour shape’s functional, structural, and Kansei features. Secondly, we proposed an improved conditional Wasserstein generative adversarial network (CWGAN) model suitable to the dataset. The generator’s loss in the model is designed to evaluate the authenticity of the generated results, while the discriminator’s loss assesses the conditional matching of these results. Finally, in case studies, the trained CWGAN was compared with the conditional variational auto-encoder (C-VAE), diffusion, Wasserstein generative adversarial network with gradient penalty (WGAN-GP) and style generative adversarial network (StyleGAN) models, demonstrating superior performance.

Research progress on constructability of 3D printed concrete

Abstract 3D printing concrete technology is an innovative building technology for green manufacturing, but in order to achieve better performance requirements, there is still a need for continuous in-depth research on 3D printing parameters, theory and the use of admixtures. In this paper, the effects of three printing parameters, interlayer interval time, nozzle travel speed and height, and nozzle shape on the constructability of 3D printed concrete were discussed, and the effects of bonding properties on the constructability of 3D printed concrete were analyzed. The study found that shortening the interval time between layers, reducing the travel speed and height of the nozzle, and choosing a triangular nozzle can improve the interlayer bond strength of 3D printed concrete, and thus improve the constructability of 3D printed concrete.
