- Publication 7 December 2022 Lightweight privacy-preserving data aggregation protocol against internal attacks in smart grid Privacy-preserving data aggregation has been studied extensively over the past decades, but there are still some concerns remained. For example, some schemes cannot resist against internal attacks, especially when the internal attack is launched by either the data centers that allocate the system security parameters or the attacker who shares the common information with the targeted user. In this paper, we propose a lightweight privacy-preserving data aggregation scheme, which is more efficient…
- Publication 7 December 2022 Accessibility, Infrastructure Provision and Residential Land Value: Modelling the Relation Using Geographic Weighted Regression in the City of Rajkot, India Amenities and infrastructure provision in urban areas are essential for the sustainable future of cities in developing countries like India. Indian cities have large development deficits and find it challenging to bridge the gap using traditional methods. Provision of these facilities costs money, which is often not available. However, access to amenities and infrastructure adds to land premium, which, if captured, can be used to finance the provision of these facilities. In India, very little…
- Publication 7 December 2022 The evolution of minimum mortality temperatures as an indicator of heat adaptation: The cases of Madrid and Seville (Spain) The increase in the frequency and intensity of heat waves is one of the most unquestionable effects of climate change. Therefore, the progressive increase in maximum temperatures will have a clear incidence on the increase in mortality, especially in countries that are vulnerable due to geographical location or their socioeconomic characteristics. Different research studies show that the mortality attributable to heat is decreasing globally, and research is centred on future scenarios. One way…
- Publication 7 December 2022 The Impact of Heat Waves on Daily Mortality in Districts in Madrid: The Effect of Sociodemographic Factors Although there is significant scientific evidence on the impact of heat waves, there are few studies that analyze the effects of sociodemographic factors on the impact of heat waves below the municipal level. The objective of this study was to analyze the role of income level, percent of the population over age 65, existence of air conditioning units and hectares (Ha) of green zones in districts in Madrid, in the impact of heat on daily mortality between January 1, 2010 and December 31, 2013…
- Publication 7 December 2022 Optimal Wind-Solar Capacity Allocation with Coordination of Dynamic Regulation of Hydropower and Energy Intensive Controllable Load With the increasing penetration of renewable energy, it becomes challenging to smoothen highly fluctuant and intermittent power output only through the conventional thermal units. In this paper, by exploiting the dynamic regulating ability of hydropower and energy intensive controllable load to reduce the power output uncertainties, an optimal wind-solar capacity allocation method is proposed. The power regulation characteristics of hydropower stations based on hydraulic head and energy…
- Publication 7 December 2022 Commercial yet social: The practices and logics of bringing mini-grid electricity to rural villages in Kenya Private mini-grid developers, which deliver power to rural communities in developing countries through for-profit business models, represent an alternative organisational model compared to traditional state-led, donor-led or community-driven models of rural electrification. However, as the ‘private model’ covers many different ways of doing business, this paper seeks to broaden our understanding of its complexities. This is done by using insights into organisational hybridity as a defining…
- Publication 7 December 2022 Valorization of bio-residuals in the food and forestry sectors in support of a circular bioeconomy: A review This literature review focuses on valorization of bio-residuals from the brewery, dairy, slaughterhouse and forestry sectors. Bio-residuals are organic wastes, side streams, or residues that remain at the end of the processing of a biological raw material. These under-utilized resources have the potential to support circular bioeconomies, given they can be valorized through viable value chains. To better understand this potential and gain insights in the opportunities for these resources, we…
- Publication 7 December 2022 A new integrative perspective on early warning systems for health in the context of climate change Climate change causes or aggravates a wide range of exposures with multiple impacts on health, both direct and indirect. Early warning systems have been established to act on the risks posed by these exposures, permitting the timely activation of action plans to minimize health effects. These plans are usually activated individually. Although they show good results from the point of view of minimizing health impacts, such as in the case of high temperature plans, they commonly fail to address…
