LT-Ready: Affordable renovation concepts that enable low-temperature heating and provided thermal comfort

The Dutch building stock has to switch to alternative energy-efficient heat sources, such as district heating or heat pumps, which will provide a lower supply temperature for the heating system in dwellings. Yet, the consensus is that dwellings need to be intensively renovated, to provide thermal comfort with low-temperature heating. However, it...

An LT- ready and economically feasible renovation façade design

The refurbishment of the Dutch post- war residential building stock provides a great potential for energy and CO2 emissions savings, since a large number of buildings were built before 1975 and under low or no energy standards. However, their refurbishment and especially zero-on-the-meter, is too expensive and it is not possible to find the...

Potential of Partially Superconducting Generators for Large Direct-Drive Wind Turbines

This paper aims at assessing the potential of partially superconducting generators for 10 MW direct-drive wind turbines by investigating their performance for a very wide range of excitation currents. Performance indicators such as shear stress and efficiency and other generator characteristics are compared for 12 different generator topologies....

Analysis of the influence of the cross-shore profile shape of the surfzone on the longshore sediment transport rates

The longshore sediment transport (it will be referred also as LST) is a core issue in the field of coastal engineering. It is among the most important nearshore processes that control the coastal morphology, and determines in large part whether shores erode, accrete, or remain stable. Consequently, it is important to be able to calculate the LST...

Influence of profile features on longshore sediment transport

Longshore sediment transport (LST) is one of the main drivers of beach morphology. Bulk LST formulas are routinely used in coastal management/engineering studies to assess LST rates and gradients. However, there is still great uncertainty in LST estimation with these bulk formulas. This uncertainty may have two sources: 1) experimental errors in...

Extending behavioral test models with symbolic data

Model-based testing is a technique to automatically generate test cases and oracles in order to test an implementation. A typical behavrial model used for model-based testing is a Labeled Transition System9LTS). However cre-ating the LTS models needed for testing is a complex task, and especially when data is involved the number of states and...

Managing conflicts in water resources allocation: A sustainable water allocation for Urumia Lake Basin in Iran

Using the Urumia lake water allocation problem as a case study, a conflict analysis method was applied to look for possibilities to resolve the problem of conflicting demands for water. First a thorough overview of the problem was made by describing the Urumia lake basin and the human activities therein as a Large Technical System. After the...
