High temperature in the city centers than its’ surroundings known as the Urban Heat Island (UHI) effect, which is causing discomfort to the urban dwellers in the summer time is gaining much attention around the world because the world is getting urbanized as it advances in technology. Alterations of surface area, improper urban planning, air pollution, etc. are causing this increasingly growing...

In order to find experts, different approaches build rankings of people, assuming that they are ranked by level of expertise, and use typical Information Retrieval (IR) measures to evaluate their effectiveness. However, we figured out that expert rankings (i) tend to be partially ordered, (ii) incomplete, and (iii) consequently provide more an order rather than absolute ranks, which is not what...

Since the signing of the Kyoto Protocol, a major e€ort has been launched in Canada to identify cost-e€ective measures to reduce greenhouse gas (GHG) emissions. Agriculture is an important contributor of methane and nitrous oxide in Canada. Over one-third of methane and almost four-®fths of nitrous oxide emissions are from agriculture either directly or indirectly. By 2010 primary agricultural p...

In Europe, water management is moving from flood defence to a risk management approach, which takes both the probability and the potential consequences of flooding into account. It is expected that climate change and socio-economic development will lead to an increase in flood risk in the Rhine basin. To optimize spatial planning and flood management measures, studies are needed that quantify f...

The traditional Dutch way to deal with piping failure in river dikes is the implementation of piping berms. The disadvantage of such a measure is the required inland space. Relief wells, on the other hand, require less or no inland space representing an attractive alternative solution. The aims of this paper are first, to show how reliability analysis of relief wells systems can be carried out,...

Properly managing supply chain risks is at the top of many supply chain managers’ agendas. However, the process of selecting preventive measures to mitigate supply chain risks is often unstructured in practice. This is also reflected in academic literature, where selecting appropriate mitigation measures is performed via qualitative and rather informal approaches. In order to fill this gap in i...

What’s the role of unilateral measures in global climate change mitigation in a post-Durban, post 2012 global policy regime? We argue that under conditions of preference heterogeneity, unilateral emissions mitigation at a subnational level may exist even when a nation is unwilling to commit to emission cuts. As the fraction of individuals unilaterally cutting emissions in a global strongly conn...

this paper presents future trends of urban wastes and their impacts on the environment of african cities using plausible mitigation scenarios. to accomplish this, an integrated dynamic model for urban waste flows was developed, tested, calibrated and validated. its parameter sensitivity was analyzed. using population projection up to 2052 with different levels of technological implementation, p...
