Attribution Theory: How is it Used?

open access: yesEDIS, 2014
Attribution theory is defined as the way that individuals envision the success or failure of their own behavior or the behavior of others. This 4-page fact sheet explains how instructors, whether formal or informal, can use this theory in their learning

Application of surface-wave tomography to mineral exploration : a case study from Siilinjarvi, Finland [PDF]

open access: yes, 2020
In order to assess the feasibility and validity of surface-wave tomography as a tool for mineral exploration, we present an active seismic three-dimensional case study from the Siilinjarvi mine in Eastern Finland. The aim of the survey is to identify the

Data mining of petrophysical and lithogeochemical borehole data to elucidate the origin of seismic reflectivity within the Kevitsa Ni-Cu-PGE -bearing intrusion, northern Finland [PDF]

open access: yes, 2020
The Kevitsa mafic-ultramafic intrusion, located within the Central Lapland Greenstone Belt in northern Finland, hosts a large, disseminated Ni-Cu-PGE sulphide deposit. A three-dimensional seismic reflection survey was conducted over the Kevitsa intrusion

Some strongly regular graphs and self-orthogonal codes from the unitary group U4(3) [PDF]

open access: yes, 2010
We construct self-orthogonal codes from the row span over F2 or F3 of the adjacency matrices of some strongly regular graphs defined by the rank-3 action of the simple unitary group U4(3) on the conjugacy classes of some of its maximal subgroups.

Underground Vertical Seismic Profiling with Conventional and Fiber-Optic Systems for Exploration in the Kylylahti Polymetallic Mine, Eastern Finland [PDF]

open access: yes, 2018
Seismic reflection methods have been used for the exploration of mineral resources for several decades. However, despite their unmatched spatial resolution and depth penetration, they only have played a minor role in mineral discoveries so far.

Predicting Missing Seismic Velocity Values Using Self-Organizing Maps to Aid the Interpretation of Seismic Reflection Data from the Kevitsa Ni-Cu-PGE Deposit in Northern Finland [PDF]

open access: yes, 2019
We use self-organizing map (SOM) analysis to predict missing seismic velocity values from other available borehole data. The site of this study is the Kevitsa Ni-Cu-PGE deposit within the mafic-ultramafic Kevitsa intrusion in northern Finland.

Shear Modulus Dispersion in Cracked and Fluid-Saturated Quartzites: Experimental Observations and Modeling [PDF]

open access: yes, 2019
The effect of pore fluids on acoustic wave dispersion in rocks with low aspect ratio crack porosity is important for the interpretation of laboratory and field observations in hard rock mineral exploration environments.

Latent heat flux and canopy conductance based on Penman-Monteith and Bouchet’s complementary hypothesis:validation over diverse biomes [PDF]

open access: yes, 2013
A novel method is presented to analytically resolve the terrestrial latent heat flux (λE) and conductances (boundary layer gB and surface gS) using net radiation (RN), ground heat flux (G), air temperature (Ta), and relative humidity (RH).

Evapotranspiration: application, scaling and uncertainty

open access: yes, 2014
Evapotranspiration (ET) represents one of the key components of the terrestrial hydrological cycle. In this research, a number of different aspects of ET estimation are studied in order to better understand the causes of uncertainty in flux estimation ...
