Reactivation of variably sealed joints and permeability enhancement in geothermal reservoir rocks
Alexandra Roma Larisa Kushnir, Michael Heap
Hydraulic stimulation of enhanced deep geothermal reservoirs commonly targets pre-existing joint networks with the goal of increasing reservoir permeability. Here, we study the permeability and strength of joint-free and jointed Buntsandstein sandstones fr ...
2023To break or not to break: The role of secondary mineralisation on joint reactivation in sandstone
Alexandra Roma Larisa Kushnir, Michael Heap
Discontinuities, including fractures and joint sets, modify the fluid transport properties and strength of rock masses. While open fractures and joints increase rock mass permeability and decrease rock mass strength, fluid flow within these structures can ...
2023Reactivating sealed joints: rock strength reduction and permeability enhancement … sometimes
Alexandra Roma Larisa Kushnir, Michael Heap
Rock masses are often criss-crossed by generations of discontinuities, including veins, fractures, and joints. The presence of fractures and joints can increase rock mass permeability and decrease rock mass strength. However, fluid flow within rock masses ...
2023Counting using deep learning regression gives value to ecological surveys
Devis Tuia, Benjamin Alexander Kellenberger
Many ecological studies rely on count data and involve manual counting of objects of interest, which is time-consuming and especially disadvantageous when time in the field or lab is limited. However, an increasing number of works uses digital imagery, whi ...
2021Freshwater Flux and Spatiotemporal Simulated Runoff Variability into Ilulissat Icefjord, West Greenland, Linked to Salinity and Temperature Observations near Tidewater Glacier Margins Obtained Using Instrumented Ringed Seals
The distribution of terrestrial surface runoff to Ilulissat Icefjord, west Greenland, is simulated for the period 2009-13 to better emphasize the spatiotemporal variability in freshwater flux and the link between runoff spikes and observed hydrographic con ...
Amer Meteorological Soc2015UC and EUC Weak Bit-Commitments Using Seal-Once Tamper-Evidence
Based on tamper-evident devices, i.e., a type of distinguishable, sealed envelopes, we put forward weak bit-commitment protocols which are UC-secure. These commitments are weak in that it is legitimate that a party could cheat. Unlike in several similar li ...
2013Micro-fabricated alkali vapor cells sealed at low temperatures with thin-film metallic bonding
Nico de Rooij, Danick Briand, Yves Pétremand
We report on the characterization of micro-fabricated alkali vapor cells, sealed by low-temperature thin-film metallic bonding. The low sealing temperatures ≤ 140°C are of high interest in view of future micro-fabricated cells using anti-relaxation wall co ...
