A novel methodology to identify and quantify deepwater-renewal processes during winter cooling in a large, deep lake (Lake Geneva)

David Andrew Barry, Ulrich Lemmin, Naifu Peng, François Mettra, Rafael Sebastian Reiss

We propose a novel methodology – heat budget decomposition – to identify and quantify different deepwater-renewal processes during a very cold spell in 2012 in a large, deep lake (Lake Geneva, 309-m depth). Combined with field observations and numerical mo ...

High-resolution impact assessment of climate change on building energy performance considering extreme weather events and microclimate – Investigating variations in indoor thermal comfort and degree-days

Kavan Javanroodi, Vahid Moussavi Nik, Mohammad Hosseini

Climate change and urbanization are two major challenges when planning for sustainable energy transition in cities. The common approach for energy demand estimation is using only typical meso-scale weather data in building energy models (BEMs), which under ...

How to improve the efficiency of a traditional dissolution dynamic nuclear polarization (dDNP) apparatus: Design and performance of a fluid path compatible dDNP/LOD-ESR probe

Andrea Capozzi, Jean-Noël Hyacinthe, Thanh Phong Kevin Lê

Dissolution Dynamic Nuclear Polarization (dDNP) was invented almost twenty years ago. Ever since, hardware advancement has observed 2 trends: the quest for DNP at higher field and, more recently, the development of cryogen free polarizers. Despite the DNP ...

Competition between cooling and shortwave radiation in shaping near-surface convection in pelagic waters of Lake Geneva

Hugo Cruz

When lake surface waters above the temperature of maximum density 4◦C cools, the verysurface fluid parcels become denser than their neighbours below. The latter process leads to a gravitationally unstable density distribution which may trigger ‘free convec ...
