Strengthening ice through cyclic loading

Journal of Glaciology, 2017
New experiments reveal that the flexural strength of fresh water, columnar-grained ice loaded normal to the columns may be increased by about a factor of two upon reversed cyclic loading at a frequency of ~0.1 Hz at stress amplitudes of 1.3–2.6 MPa.

Prototyping Formal System Models with Active Objects

, 2018
We propose active object languages as a development tool for formal system models of distributed systems. Additionally to a formalization based on a term rewriting system, we use established Software Engineering concepts, including software product lines

Signal Prediction Using U-Net CNN: Beyond Traditional RNN Approaches

IEEE Access
This paper studies signal prediction in settings where the target signal is not a continuation of an observed history but must be inferred from other simultaneously measured signals.

The effects of Ca++ on the strength of polycrystalline ice

Journal of Glaciology, 2016
Recent studies have suggested a physical link between Ca++ ions and an increase in the ductility or ‘softening’ of polycrystalline ice. In order to investigate the potential effects of Ca++ on deformation, we created sets of both undoped and CaSO4-doped ...

Design hazard identification and the link to site experience [PDF]

, 2017
The training, development and routes to charteredship of building design engineers have undergone a major transformation in recent years. Additionally, the duration and quality of site experience being gained by designers is reducing.

Increasing the flexural strength of columnar-grained ice by an icy coating

Journal of Glaciology
New experiments have revealed that a thin layer of granular ice bonded to salty and to salt-free columnar-grained ice increases flexural strength when the composite material is rapidly bent to the point of failure through brittle fracture.

Flexural behavior of porous isotropic ice under three-point bending tests

Journal of Glaciology
Understanding ice flexural behavior is essential for assessing interactions with structures in cold environments. The mechanical response of ice depends on microstructural properties, such as grain size and porosity, which vary widely in natural ice ...

Source Apportionment of Fine Organic and Inorganic Atmospheric Aerosol in an Urban Background Area in Greece

Atmosphere, 2020
Fine particulate matter (PM) originates from various emission sources and physicochemical processes. Quantification of the sources of PM is an important step during the planning of efficient mitigation strategies and the investigation of the potential ...

Bio-Processes of the Oxidation Ditch When Subjected to a Sub-Arctic Climate [PDF]

, 1972
Alaska's far northern area is sparsely populated primarily because of a severe climate which varies from northern temperate to Arctic. Construction and power costs are high. Skilled operating personnel are scarce and expensive, if available. Receiving
