This study concentrates on the response, data sending, and survey completion rates of a smartphone-based travel survey in a developing country. A smartphone-based survey reinforced by a web-based survey was conducted in 2015 in Kabul, Afghanistan. The aims of this study are: 1) to explore the effects of age and gender on the response rate of the smartphone-based travel survey, and 2) to examine how gender, age, smartphone ownership history, and occupation influence the data sending and completion rates of the smartphone-based travel survey. The results show that gender had no effects on the response rate, while age had a significant impact. In addition, gender had effect on data sending rate, and the respondents who owned smartphones for longer time were more likely to complete the survey successfully. Furthermore, the survey withdraw rate of respondents was higher on weekends in comparison to weekdays.

Traditional modeling for sound propagation in porous media has been done knowing the macroscopic physical parameters intrinsic to the material. Using Bayesian model-based analysis the uncertainties of these parameters and their effect on the accuracy of the selected model can be studied. The Horoshenkov Model [Horoshenkov, et al., JASA vol 139 (2016)], or similarly Miki Model [Miki, JASJ, vol 11, pp.25-28 (1990)], can be used to estimate the mean pore size and porosity of the material under test from measurements of surface impedance or absorption coefficient using glass beads of known diameter and layer thickness as an experimental model. The accuracy of these models can be compared using quantitative measures such as mean, variance and the interdependence of the estimated parameters. This paper discusses the error and likelihood of several models using the experimentally measured data sets. © INTER-NOISE 2019 MADRID - 48th International Congress and Exhibition on Noise Control engineering.

Agricultural runoff leading to nitrate (NO-N) and orthophosphate (PO-P) contamination poses significant environmental and public health risks. This study integrates the Soil and Water Assessment Tool (SWAT) with eXtreme Gradient Boosting (XGBoost), optimized using Optuna hyperparameter tuning, to enhance predictions of nutrient concentrations in water bodies. The hybrid SWAT-XGBoost model combines physical hydrological processes with machine learning for improved accuracy. The optimized model demonstrated significant improvements over SWAT alone, with R values increasing by up to 50 % and RMSE decreasing by up to 75 % across datasets. These results highlight the enhanced predictive capabilities of the hybrid approach in capturing nutrient transport dynamics. SHAP analysis further identified key factors, such as sediment dynamics and nutrient mineralization, as dominant drivers of contamination, providing actionable insights for effective watershed management. By integrating SHAP analysis, the study identified key processes influencing nutrient transport, such as sediment dynamics and nutrient mineralization, offering deeper insights into pollution pathways. This approach provides a scalable and adaptable framework for improving watershed management, supporting sustainable agricultural practices, and mitigating contamination risks. The findings highlight an approach that combines physical modeling with machine learning to effectively address complex environmental challenges.

Background: Patient isolation units (PIUs) can be an effective method for effective infection control. Computational fluid dynamics (CFD) is commonly used for PIU design;however, optimizing this design requires extensive computational resources. Our study aims to provide data-driven models to determine the PIU settings, thereby promoting a more rapid design process. Method: Using CFD simulations, we evaluated various PIU parameters and room conditions to assess the impact of PIU installation on ventilation and isolation. We investigated particle dispersion from coughing subjects and airflow patterns. Machine-learning models were trained using CFD simulation data to estimate the performance and identify significant parameters. Results: Physical isolation alone was insufficient to prevent the dispersion of smaller particles. However, a properly installed fan filter unit (FFU) generally enhanced the effectiveness of physical isolation. Ventilation and isolation performance under various conditions were predicted with a mean absolute percentage error of within 13%. The position of the FFU was found to be the most important factor affecting the PIU performance. Conclusion: Data-driven modeling based on CFD simulations can expedite the PIU design process by offering predictive capabilities and clarifying important performance factors. Reducing the time required to design a PIU is critical when a rapid response is required. © 2024 Elsevier Ltd

Buildings consume 42.6% of the electricity generated in Brazil, and the residential sector is responsible for 21,4% of that amount, in other words, almost a quarter of the generated electricity. Add to this fact, the housing deficit was almost 6 million in 2019 in the country. The purpose of this article is to analyze the results of the heating and cooling demand of a social residential building designed in an H shape, in Passo Fundo, in southern Brazil, from the perspective of the thermal transmittance limitation of the Brazilian normative (NBR 15575) and the Spanish Technical Code (CTE). The main objective is to verify and analyze the existing differences and potentials in the comparison between the regulations, evaluating the thermal envelope of a typical social housing building. The method used to obtain results was a computer simulation, using EnergyPlus software as an energy calculation engine and Sketchup 2017 for the modeling, with the Euclid plugin, which directly sends data to the energy simulation program. The building was simulated with climate data from the city of Passo Fundo, belonging to the Brazilian Bioclimatic Zone 2 (BZ2), and was compared to the transmittance level required for the D1 climate of Spain, as required by the CTE. Finally, it is possible to evidence that there is a decrease in the building’s energy demand as thermal insulation is incorporated into the walls and roof, to reach the strictest standard requirement levels. This article intends to show the potential for improvement in Brazilian regulations and the path to be followed concerning energy improvement in buildings.

An affordable vertical house, which is known as rusun in Indonesian term becomes the utopia of a compact city. The rusun to be the main actor contributing to the creation of liveable comfort in dense areas by relocating squatters and slum inhabitants to better living places. Technical guidelines and building standards play a major role in a building's environmental impact. These standards will be reviewed based on their impact on building performance. There are two prototypes of rusun referenced in 05/PRT/M/2007, and the assessment of these prototypes has been done by using ENVi-met. The meteorological data for the ENVI-met configuration input is adapted to the same weather and climate conditions taken from the data measured on June 13th, 2012. The analysis of this assessment will focus on building orientation, building length, building height, and also the microclimate which is impacted by these prototypes. Based on the assessment, it is recommended that the layout of outdoor space on the north side should provide as much green coverage as possible, either for shadowing or for the benefit of its albedo. The simulation shows that building ratio of 1:3 produces higher wind speed, which also controls air temperature and humidity. © Published under licence by IOP Publishing Ltd.

作者： N I Pratiwi S R Sari F Arifan A T Wulandari I Alkian B Mustasjar M B F B Aji Department of Physics Faculty of Science and Mathematics Diponegoro University Indonesia Department of Engineering Architectural Engineering Diponegoro University Indonesia Department of Industrial Chemical Engineering Technology Vocational School Diponegoro University Indonesia Nursing Science Study Program Faculty of Health Sciences Muhammadiyah University Purwokerto Indonesia Department of History Faculty of Humanities Diponegoro University Indonesia

Wastewater produced by batik industry in Cibelok Village, Pemalang that is disposed straight into the sewage will increase the concentration of Biochemical Oxygen Demand (BOD), ammonia (NH3), Chemical Oxygen Demand (COD), chromium (Cr), lead (Pb), watercolour, acidity (pH), and dissolved oxygen (DO). Disposed batik wastewater without treatment will contaminate the environment, mainly its water and soil. The main purpose of this research is to reduce the concentration of Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), ammonia (NH3), chromium (Cr), lead (Pb), watercolour, acidity, and dissolved oxygen (DO) by treating batik Cibelok's waste and not contaminate the surrounding environment. Laboratory test results on batik waste in COD, BOD, DO, ammonia, chromium, lead, colour, and acidity (pH). These results are not in accordance with the 2014 Waste Water Quality Standard Number 5 by the Regulation of the Minister of Environment of the Republic of Indonesia. Alternatives that have been done to treat Cibelok Village's batik waste is to lower dangerous substances concentration through electrocoagulation and filtration. The processes could lower COD level around 57.6%, ammonia 98%, chromium 85%, and BOD 67%. Reducing the concentration of the substance makes the batik waste safer and environmentally friendly when it's finally disposed to the sewage.
