The potential for future energy crises is a problem the world is currently facing. Many countries are switching from fossil to renewable energy to prevent an energy crisis. One of the most developed renewable energy today is solar energy. Easy installation makes solar energy installation not only on a large scale but also on a home scale. Urban areas will be very suitable for building solar photovoltaic (PV) roofs due to minimal open areas. In installing rooftop solar PV, sound planning is needed to predict the energy potential that can be provided by solar energy on the rooftop of a building. Spatial modeling can be done to determine the energy potential and suitable location for rooftop solar PV installation. In building rooftop solar PV modeling, the level of detail of the building will affect the results of the model. The rooftop's shape and the building's height will affect the amount of solar radiation going into the building. However, the higher the level of detail of the building, the higher the cost and processing time will be. This study will review the differences in modeling the potential of rooftop solar PV using different levels of detail. This research will integrate solar radiation data from remote sensing to determine the energy potential of solar radiation and digital surface model data from photogrammetry to create a level of detail for buildings. Integration of solar radiation data and the level of detail of the building will use hillshade analysis. Hillshade analysis can review the shadow effect on the rooftop of a building which will be directly related to the potential of solar energy on the rooftop of the building. This study determines the energy potential on the rooftop of the building with different levels of detail, namely 0, 1, and actual shape, to determine the difference in energy potential in the three scenarios. Hopefully, this research will determine the best level of detail for modeling rooftop solar PV. The best model that can sho

Diets rich in antioxidants from foods are linked to a lower risk of developing and progressing of noncommunicable diseases. Unlike estimates of population antioxidant intake, this study aimed to estimate the total antioxidant capacity (TAC) of meals suggested in the Dietary Guidelines for the Brazilian population (DGBP) (2014), as well as identify the main contributing foods. The research was quantitative and descriptive, based on the analysis of secondary data from photographic records of the suggested meals (breakfast, lunch, and dinner) in the DGBP. The foods, their preparation methods, and portion sizes were identified. Food TAC was mainly estimated using the Ferric-Reducing Ability Power (FRAP) method, based on Carlsen et al. (2010). Subsequently, the TAC of the meals, the percentage contribution of each food item, and the TAC adjusted to 250 kcal were estimated. The average TAC found was 3.01 ± 1.35 mmol in breakfast suggestions, 1.93 ± 0.84 mmol in lunch suggestions, and 2.49 ± 3.34 mmol in dinner suggestions, with no significant differences when comparing the TAC results among the three meals (p = 0.608). However, coffee was identified as the main contributor in breakfast suggestions, while beans stood out as the main contributor in lunch and dinner suggestions. Therefore, the foods that most prominently contributed to the TAC of the meals suggested by DGBP were those that, in addition to being part of the national food culture, are classified as natural or minimally processed. These findings reinforce the public health value of promoting diets based on natural or minimally processed foods, highlighting their importance in providing bioactive compounds which may help prevent chronic diseases and improve population health. © 2025 Elsevier B.V.

Nowadays, in order to decrease environmental impacts such as exhaustion of natural resources and CO2 discharge, the partial replacement of cement by fly ash and coarse aggregate by crushed fine aggregate in concrete have been attracted many researchers. This study concentrated on an experimental examination of the mechanical properties of fine-grained concrete using fine-red sand placement for crushed sand. Experimental tests were performed to investigate compressive, splitting tensile, and flexural strength. The results reveal that the compressive, splitting tensile, and flexural strength increased with curing time for all mixtures. The increase in the amount of fine-red sand replacement caused a decrease in all mixtures. It was also found that there is a strong correlation between compressive and splitting tensile strength with a high coefficient of determination. Besides, the results of compressive, splitting tensile, and flexural strength satisfied the requirement of concrete used for pavement. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Magnetic coupled wireless power transfer systems have been incorporated in various devices including smartphones, and are becoming important to charge multiple devices at the same time. In this paper, we propose a new circular transmitter that can efficiently charge multiple receivers. The transmitter coil consists of a parabolic spiral that is sparse on the inside and tight on the outside from the beginning. The analysis result shows that when the five receivers are charged, they can be charged almost evenly and the total efficiency is 79.2%.

This paper proposes a new method for obtaining self and mutual inductances in wireless power transfer (WPT) systems using a deep neural network (DNN). In this paper, five structural parameters of a WPT system were experimentally used as inputs. The experimental results demonstrate that inductances obtained by the proposed method are within 10% in the maximum errors and about 1% in the mean absolute errors. The proposed method is about 682k times faster than the field solver in the CPU time required to obtain the inductances of one structure.

Damage is defined as any change to the material, geometry or boundary condition that can modify the structure’s properties or response. In the past, damage identification was performed through periodical inspection, non-destructive testing/non-destructive evaluation, or visual observation. Structural health monitoring (SHM) has emerged to transition from offline damage identification to near real-time and online damage assessment. Hence, SHM is a damage detection strategy to monitor a structure for a period using a series of continuous measurement devices, which then collect the system’s characteristics and subsequently perform statistical analysis to assess the current circumstances and health of the structure. One of the first steps for the study of SHM is damage detection followed by monitoring. Machine Learning (ML) techniques can be used to develop viable algorithms to make potential predictions. ML algorithms are therefore providing the tools needed to enhance the capabilities of SHM systems and provide intelligent solutions to past challenges. Preliminary studies have reviewed that the extension of ML into SHM has dramatically increased the system’s capabilities, providing innovative solutions to different research challenges. This work conducts a study of the use of ML to identify damage in a beam and discuss the challenge of usage, performance and implementation of each technique. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Kupski, Larine Fernandes, Sibele Santos Otero, Deborah Murowaniecki Graduate Program in Food Science Faculty of Pharmacy Federal University of Bahia Campus Ondina Bahia Salvador40170-290 Brazil Food Science & Technology College of Agricultural & Environmental Science University of Georgia 706-542-3000 AthensGA30602 United States Laboratory of Food Technology School of Chemistry and Food Federal University of Rio Grande RS Rio Grande Brazil Graduate Program in Food Nutrition and Health Nutrition School Federal University of Bahia Campus Canela Bahia Salvador40110907 Brazil

The growing environmental concerns over the use of synthetic polymers have encouraged the search for biodegradable alternatives in food packaging. Among natural sources, the Cactaceae family has emerged as a promising candidate due to its abundance, sustainability, and versatile functional properties. Mucilage extracted from Opuntia cladodes and pectin obtained from Pitaya peels exhibit valuable characteristics, including antioxidant and antimicrobial activities. Furthermore, cactus fruit provides a rich source of bioactive pigments and nutrients, further enhancing the functionality of the resulting packaging materials. While the mechanical properties of current cactus-based films require further improvement through polymer blending and cross-linking techniques, their potential for extending shelf life and enabling intelligent packaging solutions is evident. This review aims to underscore the techno-functional attributes of Cactaceae species, focusing on their potential for developing biodegradable films and coatings through an in-depth literature review and bibliometric analysis. © 2025 Elsevier B.V.
