Green and sustainable power supply for sensors in pavement monitoring system has attracted attentions of civil engineers recently. In this paper, the piezoelectric energy harvesting technology is used to provide the power for the acceleration sensor and Radio Frequency (RF) communication. The developed piezoelectric bimorph cantilever beam is used for collecting the vibrational energy. The energy collection circuit is used to charge the battery, where the power can achieve 1.68 mW and can meet the power need of acceleration sensor for data collection and transmission in one operation cycle, that is, 32.8 seconds. Based on the piezoelectric-cantilever-beam powered sensor, the preliminary study on the IoT-based pavement monitoring platform is suggested, which provides a new applicable approach for civil infrastructure health monitoring.

Na região Nordeste do Brasil existe uma gama de aglomerações urbanas, dentre as quais se destaca a conurbação urbana, conhecida como Crajubar, localizada na Região Metropolitana do Cariri (RMC), no sul do Ceará, onde existe uma percepção de ausência de limites urbanos entre os três municípios: Crato, Juazeiro do Norte e Barbalha. Assim, este trabalho busca compreender a dinâmica da expansão do Crajubar, por meio de técnicas de Geoprocessamento. Para tanto, utilizou-se arquivos vetoriais da delimitação territorial com mancha urbana do ano de 2005 e imagens orbitais dos satélites GeoEye do ano de 2018. Para o processamento dos dados foi utilizado o software QGIS. O Google Earth foi usado para identificar estabelecimentos responsáveis por atraírem crescimento urbano para o seu entorno, ainda foram utilizadas informações oficiais de crescimento populacional e informações econômicas geradas pelos órgãos oficiais. Como resultados, geraram-se arquivos vetoriais com duas manchas urbanas da região, sendo uma de 2005 e outra de 2018, as quais apresentam a conurbação dos três municípios para as duas situações. A partir do mapa gerado, construiu-se o entendimento dos fatores que impulsionam a expansão espacial urbana do Crajubar, tais como serviços públicos nas áreas de infraestrutura, saúde e educação. Evaluation of expansion of Crajubar urban agglomerate using geomatics A B S T R A C TIn the Northeast region of Brazil there is a range of urban agglomerations, among which the urban conurbation known as Crajubar. It is located in the metropolitan area of Cariri (MAC), in the south of Ceará, where there is a perception of the absence of urban boundaries between the three towns: Crato, Juazeiro do Norte and Barbalha. This work tries to understand the dynamics of the expansion of Crajubar, using Geoprocessing techniques. It was used shapefiles of the territorial delimitation with urban area of the year of 2005 and GeoEye satellites images of the year of 2018. The QGIS software was used for data processing. The Google Earth was used to identify companies and institutions responsible for attracting urban growth for the around their area, official information on population growth and economic information generated by government institutions was also used. As a result, shapefiles were generated with two urban areas in the region, one of area in 2005 and another area in 2018, where each one presents the conurbation of the three towns for both situations. From the generated map, the understanding of the factors that have influenced the urban spatial expansion of Crajubar was constructed, such as public services of infrastructure, health and education.Keywords: Urbanization, Population Growth, Geoprocessing.

This afterword to the Urban Vulnerabilities: Infrastructure, Health and Stigma special issue highlights two cross-cutting themes that are addressed by all the articles in the issue, and that have the potential to make a significant contribution to debates within urban studies. First, I reflect on how the articles reveal the inseparable connections between infrastructure and stigma, demonstrating both as political and material processes that are inter-dependent and mutually constitutive. Consequently, it is urgent to bridge disciplinary siloes in bringing these scholarly debates into deeper conversation in ways that recognise the materiality of stigma and the politicisation of infrastructure (and vice versa). Second, to a greater and lesser extent, the articles all reveal the centrality of citizenship to the capacity of both urban dwellers and the state to negotiate and/or restrict access to infrastructure, and to perpetuate and/or challenge the impacts of stigma. While the connections between infrastructure and citizenship are explored in my recent work on infrastructural citizenship, the articles in this collection demonstrate the importance of temporality and scale in understanding how citizens negotiate their material and political rights.

The Sustainability value parity framework is proposed to deepen the understanding of the importance of ‘inter-relatedness' of water-energy-waste with the goal of balancing water usage, aligning energy intensity and optimizing waste utilization. Generic waste that is burgeoning is a deterrent to the practice of sustainability that aligns water, energy, infrastructure, health, food, and lifestyle (Sachs, 2007). This chapter delineates the gap between globalization at the macro-level and global citizenry at the grassroots-base and posits a value bridge assessed by appropriate thresholds of water - energy - waste. The emergent need to strengthen climate resilience and to usher into the sustainable pathway of climate-proofed development needs tuning of processes, lifestyle, hazardous substances and consumption. Climate change manifests as an over-arching risk that is strewn with unpredictability, multiple dimensions, uncertainties, spikes, imbalances leading to inequity.
