Combinação de rastreadores utilizando filtro de Kalman.

O rastreamento visual de objetos é parte vital em sistemas que realizam a percepção visual do ambiente, sendo fundamental para que as máquinas sejam capazes de ver, entender e reagir ao ambiente. O seu principal objetivo e determinar a localização de objetos de interesse em cada quadro de um vídeo de forma precisa e robusta, permitindo que aplicações de alto nível utilizem este conhecimento em suas operações. Neste trabalho é apresentado um método de rastreamento de objetos baseado em combinações de rastreadores chamado KFebT. Este método é capaz de fundir o resultado de diversos métodos de rastreamento ou métodos especialistas utilizando um filtro de Kalman. O método de fusão proposto é simples e não precisa de treinamento prévio, necessitando apenas do resultado dos rastreadores e de uma medida de confiança nesses resultados. Foram realizados testes na base de dados do Visual Object Tracking Challenge (VOT) 2015. O KFebT foi testado com combinações de dois ou três métodos de rastreamento e os resultados demonstram uma clara melhoria nos resultados comparando com o dos rastreadores utilizados em sua composição

Overcoming barriers to manufacturing digitalization:Policies across EU countries

The digital transformation of manufacturing activities is expected to bring large societal benefits in terms of productivity and sustainability. However, uptake of digital technologies is slower than desirable. As a result, governments are taking action to try to overcome some of the barriers to adoption. However, the mechanisms through which government may act are quite diverse. In this paper, we compare the national strategies across the 27 countries members of the European Union. We map each country's initiative to 14 barriers to the adoption of digital technologies in manufacturing observed in the literature. We observe that most institutional efforts focus on providing funding, developing new regulatory frameworks related to data privacy and security, and creating human capital. Some known barriers to adoption observed at the firm level, such as the lack of off-the-shelf solutions, or the need for retrofitting old equipment, are largely overlooked. We do not find any relationship between the number of initiatives proposed by each country, and the country's existing level of digitalization. We conclude by proposing several policy recommendations, as well as directions for future research

Epilithic diatoms of the suborder Sellaphorineae from Monjolinho River, São Carlos, São Paulo, Brazil

O presente trabalho é uma contribuição ao conhecimento da biodiversidade de diatomáceas epilíticas pertencentes à subordem Sellaphorineae do rio do Monjolinho, localizado no Município de São Carlos, São Paulo. O estudo taxonômico baseou-se na análise de 33 amostras coletadas no período de maio a outubro de 1998, em seis estações de coleta previamente estabelecidas. Foram identificados 31 táxons específicos e infra-específicos dos quais 29 são citações pioneiras para o estado de São Paulo. _________________________________________________________________________________ ABSTRACTThis is a survey of epilithic diatom biodiversity of Sellaphorineae from Monjolinho river, in São Carlos district, São Paulo state. The taxonomic study was carried out based on 33 samples collected between May and October 1998 at six selected stations. Thirty one specific and infraspecific taxa were identified; twenty nine of these were recorded for the first time in São Paulo state

Simulation of operational processes in hospital emergency units as lean healthcare tool

Recently, the Lean philosophy is gaining importance due to a competitive environment, which increases the need to reduce costs. Lean practices and tools have been applied to manufacturing, services, supply chain, startups and, the next frontier is healthcare. Most lean techniques can be easily adapted to health organizations. Therefore, this paper intends to summarize Lean practices and tools that are already being applied in health organizations. Among the numerous techniques and lean tools used, this research highlights the Simulation. Therefore, in order to understand the use of Simulation as a Lean Healthcare tool, this research aims to analyze, through the simulation technique, the operational dynamics of the service process of a fictitious hospital emergency unit. Initially a systematic review of the literature on the practices and tools of Lean Healthcare was carried out, in order to identify the main techniques practiced. The research highlighted Simulation as the sixth most cited tool in the literature. Subsequently, a simulation of a service model of an emergency unit was performed through the Arena software. As a main result, it can be highlighted that the attendants of the built model presented a degree of idleness, thus, they are able to atend a greater demand. As a last conclusion, it was verified that the emergency room is the process with longer service time and greater overload

Grafites apotropaicos e materialidade

Construído a partir das teorias arqueológicas pós-coloniais e de um estudo anterior sobre grafites apotropaicos de um dos autores, neste artigo discutimos a importância de deste corpus de grafites como fonte para um estudo de gênero sobre o cotidiano romano. O objetivo deste artigo é, portanto, distinto do que o inspirou, mudando a perspectiva para a importância do espaço da escrita para repensar a identidade romana no início do Principado. Argumentaremos que espaços da escrita, quando analisados a partir de sua materialidade, se torna evidência para a discussão de conflitos sociais, identidade e diversidade na sociedade romana. Também permitem uma leitura mais balanceada do Império, levando em consideração as diferentes visões de mundo das pessoas de origem humilde.  

Second Generation Ethanol - Technological Intensity on the Integrated Cycle

The purpose of this study is to investigate Second Generation Ethanol’s (SGE) production cycle in order to understand the level of SGE’s technological intensity in the integrated cycle. The suggested methodology comprises of a review of literature surrounding the requirements and indexes of technological intensity. A wide selection of database and review of specialized literature have been described to demonstrate the proposed discussion and conclusions. It has been observed that SGE puts forward a higher level of technological intensity in relation to First Generation Ethanol (FGE)

Policy Recommendations for Supporting Supply Chains with Horizontal Actions

This chapter aims to identify the supply chain (SC) issues that can be considered “horizontal”, as they are cross–sectorial and faced by most companies operating both in production and distribution sectors, and to propose a set of policy recommendations that can support public and private organisations to promote and foster innovation and competitiveness of future European SCs. The definition of the Key Horizontal Issues (KHI) is the basis for developing 12 policy recommendations regarding infrastructure requirements, technological and organisational improvements and regulatory developments needed to set the stage for the European SCs for the future. Specifically, the policy recommendations entail assuring appropriate standards and legislation for European SCs; educating and training professionals for the future SCs; drafting of international agreements aiming at future European SCs; supporting and fostering incentives and funding schemes; promoting reference bodies for European SCs; and establishing infrastructure for fostering of future European SCs
