Review of the Autobiography of Josef Svoboda, Canadian Arctic Climate Scientist

open access: yesScientia et Fides, 2018
In Wine from Raisins, Josef Svoboda, a Canadian arctic climate scientist, tells the story of his own life that encompassed 20th-century history and winds up facing the most important questions of the 21st century - questions about what we have learned ...

Case Studies of Rock Bursts in Tectonic Areas with Facies Change

open access: yesEnergies, 2019
Although tectonic areas with facies change (i.e., variation of coal seam thickness, coal seam dip angle, or coal quality) are one of the three major geological structures that induce rock bursts, case studies of rock bursts in these tectonic structures ...

Generating Realistic Geology Conditioned on Physical Measurements with Generative Adversarial Networks [PDF]

open access: yesarXiv, 2018
An important problem in geostatistics is to build models of the subsurface of the Earth given physical measurements at sparse spatial locations. Typically, this is done using spatial interpolation methods or by reproducing patterns from a reference image.

Translational Imaging Spectroscopy for Proximal Sensing

open access: yesSensors, 2017
Proximal sensing as the near field counterpart of remote sensing offers a broad variety of applications. Imaging spectroscopy in general and translational laboratory imaging spectroscopy in particular can be utilized for a variety of different research ...

“Geology in Nubibus” [PDF]

open access: yesNature, 1893
SIR HENRY HOWORTH wishes to continue the discussion of glaciation in the pages of NATURE, but I find in his last letter very good reason why this cannot be done. No discussion can lead to definite results unless the parties to it accept as data what they themselves have recently and deliberately admitted.

Universal Graphs at $\aleph_{ω_1+1}$ and Set-theoretic Geology [PDF]

open access: yesarXiv, 2016
This thesis consists of two parts: the construction of a jointly universal family of graphs, and then an exploration of set-theoretic geology. Firstly we shall construct a model in which $2^{\aleph_{\omega_1}}=2^{\aleph_{\omega_1+1}}=\aleph_{\omega_1+3}$ but there is a jointly universal family of size $\aleph_{\omega_1+2}$ of graphs on $\aleph_ ...

A Field Based Approach to Introductory Geology Instruction [PDF]

open access: yes, 1999
As part of the NSF-funded VCEPT project, geology faculty at Mary Washington College have developed and pilot tested a two-semester sequence of geology courses which are taught in a non-traditional, discovery oriented style.

The Galactic origin for the borders in the Earth history [PDF]

open access: yesOtechestvennaya geologiya [National geology], 2015, 3. pp.70-83, 2020
The external galactic key factor for developing of massive geochronological boundaries, as well as mass extinctions (ME) is proved based on chronological relationships of the impulses of globally short processes. External galactic key factor is also proved based on the coincidence of the scales of their developing processes, their regular periodicity ...

Sorption heat engines: simple inanimate negative entropy generators [PDF]

open access: yes, 2005
The name 'sorption heat engines' is proposed for simple negative entropy generators that are driven by thermal cycling and work on alternating adsorption and desorption. These generators are in general not explicitly recognized as heat engines. Their mechanism is applicable to the fields of engineering, physics, chemistry, geology, and biology, in ...
