In this paper, we present an approach that can handle Z-numbers in the context of multi-criteria decision-making problems. The concept of Z-number as an ordered pair Z=(A, B) of fuzzy numbers A and B is used, where A is a linguistic value of a variable of interest and B is a linguistic value of the probability measure of A. As human beings, we communicate with each other by means of natural language using sentences like "the journey from home to university most likely takes about half an hour." The Z-numbers are converted to fuzzy numbers. Then the Z-TODIM and Z-TOPSIS are presented as a direct extension of the fuzzy TODIM and fuzzy TOPSIS, respectively. The proposed methods are applied to two case studies and compared with the standard approach using crisp values. The results obtained show the feasibility of the approach.

Research on Biomedical Engineering 2025年第2期41卷

作者： Marcelino, Ana Carolina Rodovanski, Giovana Pascoali Bonetti, Karoline Panes, Caio Rabinovich de Almeida Martins, Fernando Moran, Cristiane Aparecida Araranguá Brazil Graduate Program in Neurosciences and Behavior Department of Experimental Psychology of the Institute of Psychology-University of São Paulo Sao Paulo Brazil Araranguá Brazil Computer Engineering Instituto Mauá de Tecnologia São Caetano do Sul Brazil Electronic Engineering and Computing with Emphasis on Electronic Devices and Systems at Instituto Tecnológico de Aeronáutica–ITA São Caetano do Sul Brazil Department of Physiotheraphy and at the Postgraduate Program in Rehabilitation Science of the Federal University of Santa Catarina-UFCS Ararangua Brazil

Purpose: The objectives of this study were to create a device with technological development of the self-inflating bag (SIB) equipment to measure the variables tidal volume, peak inspiratory pressure, and inspiratory flow and to evaluate the knowledge of undergraduate students in handling the SIB. To reduce the risks of mortality, length of hospital stay, and infections, SIB is a resource used to ventilate the patient through the inflation of the device, but it is not capable of measuring the ventilatory parameters. Excess ventilation and incorrect handling of the bag can cause lung injury in newborns. Therefore, measuring these parameters can prevent lung injury resulting from inadequate ventilation. Method: This is a cross-sectional and experimental study, with the development of a device SIB that allows the evaluation of variables of neonatal respiratory mechanics that were tested with an artificial lung. It was approved by the Research Ethics Committee and the research was developed in three stages: the first represents the search for scientific articles for the consensus of neonatal ventilatory variables for the construction of the SIB parameters;the second stage depicts the technological development of a device capable of monitoring such variables through the SIB. In the third stage, the content validation of the device with the handling of the SIB was carried out by students of medicine and physiotherapy courses of Brazil. Results: In this work, a device that analyzes the values of the main ventilatory parameters in neonatology was developed and to generate a safety range for the use of the device, curves with a tolerance of 10% up and down were created. All electronic components were coupled to the equipment, with a display that transmits the parameter values. The web page can be used on a cell phone, tablet, computer, or SmartTv, as long as it is connected to the "RespiratorIoT_AP" network. Among the 29 participants in the study, 8 said they were familiar w

The application of artificial intelligence (AI) in three-dimensional (3D) agricultural research, particularly for maize, has been limited by the scarcity of large-scale, diverse datasets. While 2D image datasets are abundant, they fail to capture essential structural details such as leaf architecture, plant volume, and spatial arrangements that 3D data provide. To address this limitation, we present AgriField3D (website), a curated dataset of 3D point clouds of field-grown maize plants from a diverse genetic panel, designed to be AI-ready for advancing agricultural research. Our dataset comprises over 1,000 high-quality point clouds collected using a Terrestrial Laser Scanner, complemented by procedural models that provide structured, parametric representations of maize plants. These procedural models, generated using Non-Uniform Rational B-Splines (NURBS) and optimized via a two-step process combining Particle Swarm Optimization (PSO) and differentiable programming, enable precise, scalable reconstructions of leaf surfaces and plant architectures. To enhance usability, we performed graph-based segmentation to isolate individual leaves and stalks, ensuring consistent labeling across all samples. We also conducted rigorous manual quality control on all datasets, correcting errors in segmentation, ensuring accurate leaf ordering, and validating metadata annotations. The dataset further includes metadata detailing plant morphology and quality, alongside multi-resolution subsampled versions (100k, 50k, 10k points) optimized for various computational needs. By integrating point cloud data of field grown plants with high-fidelity procedural models and ensuring meticulous manual validation, AgriField3D provides a comprehensive foundation for AI-driven phenotyping, plant structural analysis, and 3D applications in agricultural research. © 2025, CC BY-NC-SA.

The residents of the floating village of Malahing, Bontang, East Kalimantan, earn their living as fish catching fishermen and seaweed farming. Residents even experience a clean water crisis, every month they require a budget IDR 300, 000 until IDR 400, 000 to buy clean water at Tanjung Laut by ketinting. The PKT programmed rain harvesting for Malahing residents to supply clean water. The method used was field observations and surveys as well as simple calculations using the program of Office Excel. The PKT carried out gutter procurement for every resident's house, provided three plastic drums of 200 litres to collect rainwater, provided filters to filter rain water, train the residents to care for and repair the filters. As a result, the residents get clean water to meet their daily basic, grow vegetables for family needs and do greening in their yard and water them. They can also water communal latrines so that defecation is not carried out at sea. Malahing residents can save IDR. 356, 000 until IDR 456.000 per month, help save fossil fuels and reduce carbon dioxide emissions so they become healthier, prosperous and environmentally friendly. © 2020 IOP Publishing Ltd.

This paper presents an approach for speeding up the convergence of adaptive intelligent agents using reinforcement learning algorithms. Speeding up the learning of an intelligent agent is a complex task since the choice of inadequate updating techniques may cause delays in the learning process or even induce an unexpected acceleration that causes the agent to converge to a non-satisfactory policy. We have developed a technique for estimating policies which combines instance-based learning and reinforcement learning algorithms in Markovian environments. Experimental results in dynamic environments of different dimensions have shown that the proposed technique is able to speed up the convergence of the agents while achieving optimal action policies, avoiding problems of classical reinforcement learning approaches.

The objective of the present study was to evaluate the effect of the residence time in the oral cavity on the electrochemical and microstructural properties of nickel-titanium superelastic and thermoelastic archwires aiming at establishing optimum treatment parameters regarding materials selection and maintenance of orthodontic apparatus. The corrosion behaviour of commercial archwires of different diameters was studied after periods of use from 1 to 3 months in the oral cavity of patients submitted to orthodontic treatment. Electrochemical measurements and scanning electron microscopy (SEM) were performed. The results revealed that the stiffness of superelastic archwires increased upon use, making it unnecessary to replace archwires in the early stages of treatment with the objective of adapting the diameter of the wire. Electrochemical tests suggested extremely high corrosion resistance of the nickel-titanium alloy even in severe acid environment. SEM images revealed limited pit formation concentrated in the archwire-bracket contacts. © The Electrochemical Society.

Regarding the solution of combinatorics problems, is important to evaluate the cost and the benefit among obtaining solutions of high quality in detriment of the computational resources required. The problem presented here is about the routing of a vehicle with pickup and delivery of product with time window constraints. This problem requires to be attended with instances of great scale (nodes ≥ 100). We have a large quantity of nodes with restrictions of time windows (≥ 90%) and with a large factor of amplitude (≥ 75%) as well. The problem is NP-hard and for such motive the application of an exact method of solution to resolve it, is limited by the practical time for routing. This paper proposes a specialized genetic algorithm, which offers solutions of good quality in computational times that do useful its application. © 2005 IEEE.

Our problem is about a routing of a vehicle with product pickup and delivery and with time window constraints. This problem requires to be attended with instances of medium scale (nodes ≥ 100). A strong active time window exists (≥ 90%) with a large factor of amplitude (≥ 75%). This problem is NP-hard and for such motive the application of an exact method is limited by the computational time. This paper proposes a specialized genetic algorithm. We report good solutions in computational times below 5 minutes. © Springer-Verlag Berlin Heidelberg 2005.
