The recognition of traffic signs is one of the many utilities enabled by embedded systems. Through the use of vehicle cameras, it is possible to capture and classify traffic signs with the aid of Artificial Intelligence, specifically Convolutional Neural Networks. In addition to addressing the basic problem solved in the literature, which consists of detecting and classifying the type of traffic sign, the present project achieved a methodology for creating databases and models to evaluat...
Currently, there is a feeling of public insecurity in the world, as tranquility and order have been stolen by terrorist attacks, gender violence and other crimes against people and property. Writing and researching on the issue of crime and violence is not an easy task, much less facilitated by government agencies that have a monopoly on recording, handling and systematizing data on facts and phenomena that involve public safety. In Brazil, the Federal Government, in an attempt to r...
Aphasia is a language disorder caused by injury or dysfunction in the brain and directly affects the individual's communication. The most common cause of aphasia is stroke and traumatic brain injury (TBI), mainly in the left hemisphere, where language function is usually located. Approximately one-third of people who have had a stroke develop aphasia. The severity of aphasia changes over time, and some aspects of language may improve, while others remain compromised. The aphasic ind...
Air pollution is a critical factor that harms biodiversity, ecosystems, and human health. The increase in pollutant concentrations due to the growth of urban and industrial areas has led to increased scientific discussions on this topic, and computational modeling is an important management tool for decision-making. In this sense, the main objective of this work is to evaluate the performance of the air quality model WRF-Chem (Weather Research and Forecasting with Chemistry) to determine...
The purpose of Knowledge Transfer (KT) is the practical use of the results of scientific research and the monitoring of the health benefits it brings to the population. In health care, the government and society expect that investments made in research will yield results that go beyond the production and publication of knowledge and lead to practical outcomes such as public policies, systems, products, and technologies to benefit the health of the population. However, there is still a ne...
Fires can cause immeasurable losses for both living beings and material goods, they can affect structures, forests, undergrowth, vehicles, and other environments, with structures being the place with the highest incidence of fire. In this way, it is essential to resolve its occurrence, or in the event of an accident, act effectively to suppress it immediately. Therefore, it is necessary to invest in prevention and protection measures. The design of effective firefighting solutions permea...
With the emergence of e-procurement, public purchases are mostly conducted through the Electronic Auction – the federal government's procurement system where bids for the acquisition of common goods and services are processed via the web. Employing the literature applied to Public Procurement, based on the efficiency and effectiveness of hiring. This research, which is in the “Three Paper Thesis” format, examined with a deductive approach the terms and efficiency of technical units throu...
Oil pipelines are susceptible to leaks. Particularly, pipelines from onshore oil production fields have characteristics that accentuate leak problems, as they are spread over large areas and have systems interconnected by pipelines laid on the surface. Furthermore, they are mostly old systems that operate without continuously present human assistance. As a result, they are more prone to failure. This work proposes a proof of concept of a monitoring system based on the internet of things ...
The world’s energy matrix still focuses on the exploitation of fossil fuels. Thus, most producing companies are dedicated to maximizing the oil recovery factor, especially from mature fields. Production is declining and lack new technologies, such as advanced oil recovery (EOR), to maintain oil production in the reservoir. In this perspective, one of the most promising EOR techniques is the injection of surface-active agents or surfactants. The major benefit of using these compounds is t...
The efficient management of water resources is a crucial challenge for global sustainable development. Therefore, sustainable water governance requires an interdisciplinary approach that integrates knowledge about environmental, social, and technological processes and inclusive strategies involving scientists, managers, politicians, and public and private initiatives to produce collaborative solutions and contribute to water security. The WRF-Hydro system represents the state of the art in...
