Vulnerability Maps

Vulnerability maps are useful for groundwater protection, water resources development, and land use management. The literature contains various approaches for intrinsic vulnerability assessment, and they mainly depend on hydrogeological settings and anthropogenic impacts. Most methods assign certain ratings and weights to each contributing factor to groundwater vulnerability. Fuzzy logic (FL) is an alternative artificial intelligence tool for overlay analysis, where spatial properties are fuzzified. Unlike the specific rating used in the weighted overlay-based vulnerability mapping methods, FL allows more flexibility through assigning a degree of contribution without specific boundaries for various classes. This study compares the results of DRASTIC vulnerability approach with the FL approach, applying both on Qatar aquifers. The comparison was checked and validated against a numerical model developed for the same study area, and the actual anthropogenic contamination load. Results show some similarities and differences between both approaches. While the coastal areas fall in the same category of high vulnerability in both cases, the FL approach shows greater variability than the DRASTIC approach and better matches with model results and contamination load. FL is probably better suited for vulnerability assessment than the weighted overlay methods.

The use of aluminium alloy instead of steel for the structural components of a 32 ton articulated lorry has been examined. The probable manufacturing difficulties have been assessed and shown to be minimal. The savings in weight possible by using aluminium have been calculated from a structural analysis of the cab, tractor chassis and trailer and from this and an assessment of the manufacturing processes the extra cost of manufacturing in aluminium has been determined. A typical case study shows that this extra cost can be easily recovered by utilising the increased load capacity of the vehicle during the first few years of its life.

Today, suburbs and urban fringes are pivotal places for understanding contemporary urban transformations because the majority of the world’s urban population live in suburbs. Suburbanization (i.e. the process of combining the non-centric population, economic growth, and spatial expansion) and suburbanisms (suburban ways of living) are key concepts for observing these transformations, framed under the umbrella of the post-suburban theoretical framework. This paper relies on a post-suburban standpoint as it enables the complexity of the diverse transformations at the urban edges to be addressed. On such basis, this paper discusses the outcomes of a qualitative case study conducted on the most recently built neighbourhood of Fiano Romano, a suburb of Rome that has faced a number of socio-spatial transformations over the past two decades. The study illustrates the diverse complexities related to the provision of welfare services and public amenities such as water and social infrastructures. In so doing, the article unfolds the shape of a ‘new suburbia’ characterized by emerging socio-spatial changes that lie in processes of peripheralization, which characterize many contemporary post-Fordist suburban areas, especially at the present time of the coronavirus crisis. The article points out the centrality of suburban ways of living in studying issues involving both spatial planning and governance of welfare. Furthermore, the article highlights the idea that new inequalities and deprivations are taking place in diverse suburban areas, and that such aspects deserve further governance agendas able to meet the suburban social demands that differ from traditional urban vulnerabilities.

Performance-Based Plastic Design (PBPD) is a structural analysis that can be used to review structural performance. This method is increasingly popular to be used in the earthquake-prone area. This method is based on energy method that can be applied to steel or concrete structures. Meanwhile, Indonesia has already SNI 1726:2102 to be used as a guide in designing the thrust load to review the level of structural performance. Both of these things need to be used as a reference in areas that were initially considered safe from the earthquake but based on the development of earthquake micro zonation maps, it is very possible to become potential areas that also become earthquake regions. For this reason, the case of the structure that was built in the Pekanbaru area was taken. From the analyses of structural behavior, the structure that applied PBPD has greater displacement than the structures that apply the thrust load of SNI 1726: 2012. The percentage of displacement that occurred was 8-37 %. Based on performance analysis, the structures according to PBPD shows a better level of performance to the application of SNI 1726: 2012 thrust load.
