The central role of the car in city mobility has led to a decreased capacity for people to choose another alternative form of mobility. In recent decades, some cities have set policies where cycling has become increasingly important. Urban mobility policies in response to Covid-19 have reinforced this perspective. Throughout the analysis of urban bicycle studies, the paper investigates the role of mobility for society and the design of our cities? What the role of sustainable mobility, in particular how the bicycle is addressing the Covid-19 emergency. During and after this emergency, the use of the bicycle addresses urban quality and liveability for spaces. The research studies the urban policies of 5 cities: Barcelona, Bogota, Brussels, Milan and Paris and analyses the measures implemented during the first lock down, since February 2020 to May 2020. In all cities studied, the bicycle modal shares and the bicycle infrastructure has increased. Covid-19 allowed the bicycle to prove it is the safest, most efficient urban mode of transport. The action carried out, in the cities studied, affected not only on the hard aspects reshaping the cities with permanent and temporary solutions but also on soft aspects acting on people's perception and use and choosing how to move. Transport studies and policies involving bicycles are not just 'about cycling', but about sustainable, productive, and prosperous cities.
汽车在城市交通中的核心作用导致人们选择另一种交通方式的能力下降。近几十年来,一些城市制定了政策,让骑自行车变得越来越重要。应对Covid-19的城市交通政策强化了这一观点。通过对城市自行车研究的分析,本文探讨了流动性对社会的作用以及我们城市的设计。可持续交通的作用,特别是自行车如何应对Covid-19紧急情况。在此紧急情况期间和之后,自行车的使用解决了城市质量和空间的宜居性。该研究研究了5个城市的城市政策:巴塞罗那、波哥大、布鲁塞尔、米兰和巴黎,并分析了自2020年2月至2020年5月第一次封锁期间实施的措施。在所有被研究的城市中,自行车模式的共享和自行车基础设施都有所增加。新冠疫情让自行车证明了它是最安全、最有效的城市交通方式。在研究的城市中,所开展的行动不仅影响了用永久和临时解决方案重塑城市的硬方面,而且影响了人们的感知和使用以及选择如何移动的软方面。涉及自行车的交通研究和政策不仅仅是关于“骑自行车”,而是关于可持续、富有成效和繁荣的城市。

In this work, a comparative analysis between Gaussian and Golden wavelets is presented. These wavelets are generated by the derivative of specific base functions. In this case, the order of the derivative also indicates the number of vanishing moments of the wavelet. Although these wavelets have a similar waveform, they have several distinct characteristics in time and frequency domains. These distinctions are explored here in the scale space. In order to compare the results provided by these wavelets for a real signal, they are used in the decomposition of a signal inserted in the context of structural health monitoring.
本文对高斯小波和金小波进行了比较分析。这些小波是由特定基函数的导数产生的。在这种情况下,导数的阶数也表示小波消失矩的个数。虽然这些小波具有相似的波形,但它们在时域和频域上有几个不同的特征。这些区别在这里的尺度空间中进行了探讨。为了比较这些小波对实际信号提供的结果,将它们用于结构健康监测中插入的信号的分解。

Trends in Computational and Applied Mathematics is a new journal published by the Brazilian Society for Computational and Applied Mathematics (SBMAC). SBMAC was established in 1978 as a scientific organization aimed at developing and promoting Computational and Applied Mathematics in Brazil. It is a leading environment for researchers, professionals and students working in Applied Mathematics and related fields. Currently, SBMAC has over 300 members and it organizes the largest scientific event in t his field in Latin America, the National Congress of Computational and Applied Mathematics (CNMAC), an annual congress that attracts around 700 attendees. Furthermore, SBMAC organizes regional events and co sponsors many other events in Brazil. In 1999, SBMAC created the journal Tendencias em Matematica Aplicada e Computacional (TEMA), which was originally devoted to papers presented at CNMAC and to the dissemination of Applied Mathematics in Portuguese. With the publication of 21 volumes, the jornal has grown and has become a leading Brazilian journal in the field. In the past few years, the great increase in the number of submissions in English, by Brazilian and foreigner researchers alike, shows that TEMA has attracted an international audience and is recognized as an important publication in Computational and Applied Mathematics. The new journal, Trends in Computational and Applied Mathematics, marks the rebirth of TEMA as a truly international journal, yet one that preserves its history and the high profile that it has achieved. Our goals are to publish original research, theoretical developments and case studies on promising themes; to offer an interdisciplinary and reliable international forum; to provide an efficient peer review system, leading to a fast response time to the first decision. For forthcoming issues of TCAM, we invite researchers in Applied Mathematics and related fields to submit papers with innovative and/or relevant contributions to Computational and Applied Mathematics. We hope you enjoy reading the first issue of the new TCAM. We are looking forward to receiving your future contributions, as well as any comments and suggestions you may have. We will try our best to adjust to the expectations of our readership.

Neste trabalho introduzimos os conceitos de coloracao total absolutamente equilibrada e composicao de grafos. Provamos que para n , k in mathbb{N}, se ( k + 1)| n , existe um grafo k -regular conexo com n  vertices que admite uma coloracao total absolutamente equilibrada com no maximo Delta +2 cores. Esse resultado mostra que existe uma relacao entre a regularidade e o numero de vertices do grafo que possibilita a construcao de uma familia de grafos regulares, denominados grafos harmonicos. Em seguida, mostramos que todo grafo harmonico de grau k pode ser obtido como composicao sucessiva de grafos completos de grau k . Finalizamos, provando que os grafos harmonicos nao possuem vertice de corte, fato que implica que todo grafo desta familia possui conectividade de vertices kappa(G) geq 2.

O fluxo da água em meios porosos é governado por uma equação diferencial parcial (a equação de Richards), cuja forma mista envolve as variáveis umidade do solo e potencial mátrico. A curva de retenção é uma relação não linear entre estas variáveis, fundamental no estudo da dinâmica da água no solo na zona vadosa. Um dos objetivos deste trabalho á avaliar o modelo de curva de retenção da água no solo que melhor ajusta os dados mensurados de umidade e potencial mátrico, obtidos a partir de um experimento realizado na Universidade Federal Rural do Rio de Janeiro. No presente artigo, um Algoritmo Genético (AG) é proposto de forma a buscar os parâmetros de ajuste que maximizam o coeficiente de determinação, considerando três horizontes de solo e os seguintes modelos de curvas de retenção: van Genuchten, Brooks-Corey e Haverkamp. A performance do AG implementado é avaliada comparando os resultados obtidos com o programa SWRC Fit, que usa o método determinístico de Levenberg-Marquardt. A partir dos resultados obtidos pode-se observar que o AG ajustou com maior precisão os dados mensurados e o modelo Haverkamp apresentou o maior coeficiente de determinação. Além disso, o esquema de discretização da equação de Richards proposto se apresentou mais estável usando o modelo Haverkamp como curva de retenção da água no solo.
多孔介质中的水流由偏微分方程(理查兹方程)控制,其混合形式包括土壤湿度和基质势变量。保持曲线是这些变量之间的非线性关系,是研究vadosa带土壤水分动力学的基础。本研究的目的之一是评估土壤水分保持曲线模型,该模型最适合从里约热内卢联邦农村大学进行的一项实验中获得的水分和基态电位测量数据。本文提出了一种遗传算法(ga),在考虑van Genuchten、Brooks-Corey和Haverkamp三种土壤层位和保持曲线模型的情况下,寻求使决定系数最大化的拟合参数。采用Levenberg-Marquardt确定性方法,将所得结果与SWRC Fit程序进行比较,对所实施的AG的性能进行了评价。结果表明,AG对测量数据的调整精度更高,Haverkamp模型的决定系数最高。此外,以Haverkamp模型为土壤水分保持曲线,提出的理查兹方程离散化方案更加稳定。
