Parallel driving in CPSS: a unified approach for transport automation and vehicle intelligence

The emerging development of connected and automated vehicles imposes a significant challenge on current vehicle control and transportation systems. This paper proposes a novel unified approach, Parallel Driving, a cloud-based cyberphysical-social systems U+0028 CPSS U+0029 framework aiming at synergizing connected automated driving. This study first introduces the CPSS and ACP-based intelligent machine systems. Then the parallel driving is proposed in the cyber-physical-social space, considering interactions among vehicles, human drivers, and information. Within the framework, parallel testing, parallel learning and parallel reinforcement learning are developed and concisely reviewed. Development on intelligent horizon U+0028 iHorizon U+0028 and its applications are also presented towards parallel horizon. The proposed parallel driving offers an ample solution for achieving a smooth, safe and efficient cooperation among connected automated vehicles with different levels of automation in future road transportation systems

Neural Network Based Uncertainty Prediction for Autonomous Vehicle Application

This paper proposes a framework for uncertainty prediction in complex fusion networks, where signals become available sporadically. Assuming there is no information of the sensor characteristics available, a surrogated model of the sensor uncertainty is yielded directly from data through artificial neural networks. The strategy developed is applied to autonomous vehicle localization through odometry sensors (speed and orientation), so as to determine the location uncertainty in the trajectory. The results obtained allow for fusion of autonomous vehicle location measurements, and effective correction of the accumulated odometry error in most scenarios. The neural networks applicability and generalization capacity are proven, evidencing the suitability of the presented methodology for uncertainty estimation in non-linear and intractable processes

“Ocupamos as ruas com estandartes, confetes e serpentinas mostrando que o Rio é nosso”: O carnaval dos blocos de rua como espaço de luta política pelo direito à cidade

A discussão sobre direito à cidade vem sendo reatualizada nos últimos anos no campo das ciências humanas. Ela também passou a fazer parte do discurso dos movimentos sociais e culturais que, além de se apropriarem do conceito teórico desenvolvido por Lefebvre e Harvey, o ressignificam, atribuindo novas e múltiplas interpretações. Atualmente, o carnaval dos blocos de rua na cidade do Rio de Janeiro está pensando na festa como espaço privilegiado de disputas na arena política. Muitos blocos, associações e coletivos carnavalescos incorporaram em seus discursos as reivindicações em torno do direito à cidade, em um processo de carnavalização da política na e pela cidade. Este artigo busca compreender qual é o entendimento que os blocos de carnaval de rua estão utilizando para construir suas próprias reivindicações em torno do direito à cidade, discutindo e reivindicando o espaço urbano e suas vivências a partir de especificidades como gênero e sexualidade.The discussion regarding the right to the city has been recently updated in the field of human sciences. It was also included in the discourse of social and cultural movements that, in addition to appropriating the theoretical concept developed by Lefebvre and Harvey, reframe it, attributing new and multiple interpretations. Nowadays, the street carnival in the city of Rio de Janeiro is seeing the party as a privileged place for disputes in the political arena. Many carnival groups, associations and collective organizations incorporated in their speeches the claims about the right to the city, in a process of carnivalization of politics in and by the city. This article seeks to understand what is the understanding that street carnival blocks are using to build their own claims around the right to the city, discussing and claiming the urban space and its experiences based on specificities such as gender and sexuality

CIDADE E POLÍTICA: DISPUTAS DE NARRATIVAS NO CARNAVAL DE RUA CARIOCA

Carnival is built through disputes, acting as a space for political claims. Recently, Rio de Janeiro's street carnival strengthens their political struggles, mainly through the discussion of the right to culture and the city. This article seeks to comprehend, by means of ethnographic research, interviews, bibliographic review and study of media reports, the political and symbolic positions of social actors in relation to the party and the city. The appropriations and resignations of such subjects around the uses of town will be analyzed. The present work will seek to understand, therefore, what are the narratives undertaken by these carnival blocks, which transform the street carnival into a significant space of political struggle. Thus, the vision of carnival as a popular festival becomes more complex. Through playfulness, this cultural manifestation creates a current and intersectional political agenda, articulating the rights to the city, to carnival and to culture.Il y a beaucoup de dispute pour la construction du Carnaval, parce que c’est un espace de revendications politiques. Ces dernières années, le carnaval de rue carioca a potentialisé les luttes politiques, principalement par la discussion sour le droit à la culture et à la ville. Dans l’article, on utilise des recherches ethnographiques, interviews, revue bibliographique et étude des reportages des médias pour essayer de comprendre les positions politiques et symboliques presentées par les acteurs sour la fête et la ville. Ainsi, on analyse les appropriations et redefinitions des usages de l'espace public effectuées par ces acteurs. Ensuite, on examine quels sont les narratifs presentés par les fêtes de rue – appelés “blocos” -, qui transforment le carnaval de rue en un espace significatif de lutte politique. Donc, la vision du carnaval devient plus complexe, parce qu’il s’agit d’une fête populaire qui, par la fantaisie, construit un agenda politique qui articule les droits à la ville, au carnaval et à la culture d’une manière actuel et intersectionnel.O carnaval é construído por meio de disputas, atuando como espaço de reivindicações políticas. Nos últimos anos, o carnaval de rua carioca vem potencializando as lutas políticas, principalmente através da discussão do direito à cultura e à cidade. Este artigo procura entender, por meio de pesquisa etnográfica, entrevistas, revisão bibliográfica e estudo de reportagens em mídias, os posicionamentos políticos e simbólicos dos agentes ativos em relação à festa e à cidade. Logo, serão analisadas as apropriações e ressignificações de tais sujeitos em torno dos usos do espaço público. A partir disso, o presente trabalho buscará compreender quais são as narrativas empreendidas por esses blocos, que transformam o carnaval de rua em um significativo espaço de luta política. Complexifica-se, assim, a visão do carnaval enquanto festa popular que, através do lúdico, constrói uma pauta política atual e interseccional, articulando os direitos à cidade, ao carnaval e à cultura

Energy management in plug-in hybrid electric vehicles: recent progress and a connected vehicles perspective

Plug-in hybrid electric vehicles (PHEVs) offer an immediate solution for emissions reduction and fuel displacement within the current infrastructure. Targeting PHEV powertrain optimization, a plethora of energy management strategies (EMSs) have been proposed. Although these algorithms present various levels of complexity and accuracy, they find a limitation in terms of availability of future trip information, which generally prevents exploitation of the full PHEV potential in real-life cycles. This paper presents a comprehensive analysis of EMS evolution toward blended mode (BM) and optimal control, providing a thorough survey of the latest progress in optimization-based algorithms. This is performed in the context of connected vehicles and highlights certain contributions that intelligent transportation systems (ITSs), traffic information, and cloud computing can provide to enhance PHEV energy management. The study is culminated with an analysis of future trends in terms of optimization algorithm development, optimization criteria, PHEV integration in the smart grid, and vehicles as part of the fleet

Diagnostic Ability of Macular Nerve Fiber Layer Thickness Using New Segmentation Software in Glaucoma Suspects

Purpose. To assess the capacity of internal retinal layer thickness measurements made at the macula using new spectral-domain optical coherence tomography (OCT) software to distinguish between healthy subjects and those with suspected glaucoma. The diagnostic performance of such measurements also was compared with that of conventional peripapillary retinal nerve fiber layer (RNFL) thickness measurements. Methods. The study included 38 subjects with suspected glaucoma and 38 age-matched healthy subjects. In one randomly selected eye of each participant, thickness measurements at the level of the macula were made of the nerve fiber layer (mRNFL), the ganglion cell layer (GCL), and the ganglion cell complex (GCC; GCL + internal plexiform layer) through automated OCT segmentation. Peripapillary RNFL thickness (pRNFL) also was determined using the conventional scan. Results. As the only variable showing intergroup variation, mRNFL in the glaucoma suspects was significantly thinner in the quadrants inner inferior (P = 0.003), inner temporal (P = 0.010), and outer inferior (P = 0.017). The variable best able to discriminate between the two groups was inner inferior mRNFL thickness, as indicated by an area below the receiver operating characteristic (ROC) curve of 0.742. Conclusions. Macular RNFL thickness measurements showed an improved diagnostic capacity over the other variables examined to distinguish between healthy subjects and glaucoma suspects

It is a simultaneous global mega-sequencing campaign aiming to generate the largest standardized microbial data set in a single day. This will be achievable only through the coordinated efforts of an Ocean Sampling Day Consortium, supportive partnerships and networks between sites. This commentary outlines the establishment, function and aims of the Consortium and describes our vision for a sustainable study of marine microbial communities and their embedded functional traits

Natural History of MYH7-Related Dilated Cardiomyopathy

BACKGROUND Variants in myosin heavy chain 7 (MYH7) are responsible for disease in 1% to 5% of patients with dilated cardiomyopathy (DCM); however, the clinical characteristics and natural history of MYH7-related DCM are poorly described. OBJECTIVES We sought to determine the phenotype and prognosis of MYH7-related DCM. We also evaluated the influence of variant location on phenotypic expression. METHODS We studied clinical data from 147 individuals with DCM-causing MYH7 variants (47.6% female; 35.6 +/- 19.2 years) recruited from 29 international centers. RESULTS At initial evaluation, 106 (72.1%) patients had DCM (left ventricular ejection fraction: 34.5% +/- 11.7%). Median follow-up was 4.5 years (IQR: 1.7-8.0 years), and 23.7% of carriers who were initially phenotype-negative developed DCM. Phenotypic expression by 40 and 60 years was 46% and 88%, respectively, with 18 patients (16%) first diagnosed at <18 years of age. Thirty-six percent of patients with DCM met imaging criteria for LV noncompaction. During follow-up, 28% showed left ventricular reverse remodeling. Incidence of adverse cardiac events among patients with DCM at 5 years was 11.6%, with 5 (4.6%) deaths caused by end-stage heart failure (ESHF) and 5 patients (4.6%) requiring heart transplantation. The major ventricular arrhythmia rate was low (1.0% and 2.1% at 5 years in patients with DCM and in those with LVEF of <= 35%, respectively). ESHF and major ventricular arrhythmia were significantly lower compared with LMNA-related DCM and similar to DCM caused by TTN truncating variants. CONCLUSIONS MYH7-related DCM is characterized by early age of onset, high phenotypic expression, low left ventricular reverse remodeling, and frequent progression to ESHF. Heart failure complications predominate over ventricular arrhythmias, which are rare. (C) 2022 The Authors. Published by Elsevier on behalf of the American College of Cardiology Foundation
