Desenvolvimento sustentável, desenvolvimento como liberdade e a construção da cidadania na perspectiva ambiental

No contexto moderno, pensar o desenvolvimento sustentável é analisar a relação entre desenvolvimento econômico e meio ambiente e buscar mecanismos de equilíbrio entre ambos para que o homem, com liberdades mínimas, isto é, com condições suficientes para sobrevivência, construa a sua autonomia, sua cidadania e sua liberdade frente ao desenvolvimento econômico sem desprezo ao meio ambiente e identificar, na ecologia de restauração, a fundamentação cidadã do desenvolvimento sustentável

Metodologia para otimização de estrutura de produtos da linha branca via simulação numérica aliada ao projeto de experimentos

Resumo: O principal material usado pela indústria é o aço, onde as propriedades mecânicas são determinantes no processo de conformação de peças. Um dos objetivos da indústria é otimizar custos e processos e ter confiabilidade em seus produtos. Para um produto constituído por componentes produzidos com chapa de aço, um componente desempenha um papel importante no processo de uma forma geral, por isso é necessário conhecer todos os parâmetros do aço que compõem sua respectiva fabricação, bem como as propriedades do material e mais precisamente o seu processo de fabricação, para reduzir-se a espessura de tais componentes. O estudo será feito em uma estrutura de peças conformadas da linha branca. O objetivo geral é o de estudar o comportamento dos componentes com redução de espessura da chapa afim de que suportem os mesmos esforços estruturais originais. O trabalho apresenta a revisão bibliográfica com a finalidade de entender os fenômenos de falhas que podem ocorrer com a redução da espessura de chapa. Um modelo matemático bidimensional em software de CAD para uma simulação numérica de redução de espessuras em software de CAE é examinado. Finalmente, desenvolve-se uma metologia de otimização baseado em estudo matemático e estatístico para calcular algebricamente a estimativa possível de redução de espessura da chapa em relação a sua estrutura original. Chegou-se a conclusão através dos estudos acima que é possível diminuir a espessura de componentes montados numa estrutura mecânica para se otimizar custos e processos e garantir a segurança do produto dentro das normas estabelecidas

Extension of the Semantic Sensor Network Ontology for Wireless Sensor Networks: The Stimulus-WSNnode-Communication Pattern

International audienceWireless Sensor Networks (WSN) are designed to collect large amounts of heterogeneous data to monitor environmental phenomenon. Our aim is to adapt WSN nodes communication to their context, in order to optimize the lifetime of the network. Our description of context and WSN characteristics are based on ontologies. Based upon a critical analysis of existing ontologies which formalize the WSN domain, we determine that the Semantic Sensor Network (SSN) ontology is the most suitable to represent the WSN issues. However, as the communication data policy is not characterized either by SSN or by other ontologies, we propose to enrich the SSN ontology with a new pattern describing communication. In this paper, we will first integrate the different concepts related to WSN in the SSN ontology and then we will use the resulting ontology, called Wireless Semantic Sensor Network ontology, in an agri-environmental scenario to illustrate the interest of our approach

Innovations in courts: Validation of a scale of technological innovation

The development of studies on technological innovations in the public sector, specifically in justice system, is still little explored in the literature. This article aimed to develop and validate a scale of technological innovation in the justice system during the period of the COVID-19 pandemic. Data collection procedures were carried out by means of questionnaires sent to 20.727 e-mails of civil servants and judges of the state courts of justice in Brazil. The relationships among the innovation variables that make up the technological innovation construct in the Brazilian judiciary were studied. The factor analyses resulted in the main factors listed by the respondents, as the innovative trend factor (IT); technological resources factor (TR); governance factor and its evidence (G); and innovation and technology factor (IT). For responses to the studies, descriptive statistical analysis was performed, and the innovative sensitivity and technological integration variables presented greater commonalities, and the two factors extracted explain 74% and 67% of the variance. After the descriptive statistical treatment, the confidence level was 99% and the error margin was 4.87%, resulting in a sample of 679 respondents

A new management method for wireless sensor networks

International audienceThe Wireless Sensor Networks (WSN) with their constant evolution, need new management methods to be monitored efficiently by taking into account the context and their constraints such as energy consumption, reliability and remote monitoring. WSN has diverse application domains: smart home, smart care, environmental data collection etc. In order to manage a large scale WSN, several Wireless sensor network Management Tools (WMTs) are developed. Some of them use SNMP protocol like because it is impossible to implement the full compliance classical SNMP standard on each wireless sensor node. Therefore, it is important to develop a new WMT with a restricted SNMP standard dedicated to WSN applications. In this paper, we present a new WMT named LiveNCM: LiveNode Non invasive Context-aware, and modular Management tool. LiveNCM is divided into two main parts: one is centralized on the fixed network structure and another one, distributed on each node. Each part introduces the concept of non-invasive context-aware to reduce data exchanges and diagnoses the wireless sensor node state with few messages. Moreover, nodes are based on a configurable modular architecture enables to adapt to an application and to a local node constraints. LiveNCM is implemented on the LiveNode platform to validate the energy consumption and on a UNIX system to validate the adopted SNMP sub-agent. Ultimately, a decreasing data exchange and an improvement in the energy consumption in the entire WSN were observed. An implementation of the proposed management method is presented

Soybean Production Under Drought Stress with Application of Bradyrhizobium Japonicum Induced by Genistein

A research about production of soybean under drought stress with the application of Bradyrhizobium japonicum induced by genistein was conducted in green house, Faculty of Agriculture, University of Sumatera Utara. The aim of the research was to study the role of B. japonicum induced by genistein on soybean production. The experiment used Randomized Complete Block Design Factorial with three factors. The first factor was genistein treatments consisted of without and with genistein. The second factor was B. japonicum consisted of without B. japonicum, B. japonicum isolate 1, B. japonicum isolate 2 and B. japonicum isolate 3. The third factor was soil water content condition namely 40%, 60% and 80% of field capacity. The parameters observed were plant growth rate, relative growth rate, nett assimilation rate, dry weight/plant and dry weight of 100 seeds. The result research showed that the treatment of interaction between B. japonicum induced genistein under 80% of field capacity gave the higher plant growth rate, plant growth rate, relative growth rate, nett assimilation rate and dry weight of 100 seeds
