![]() These resources are in turn garnered by controlling special points on the map and/or possessing certain types of units and structures devoted to this purpose. In a typical RTS game, it is possible to create additional units and structures, generally limited by a requirement to expend accumulated resources. In a real-time strategy game, each participant positions structures and maneuvers multiple units under their indirect control to secure areas of the map and/or destroy their opponents' assets. ![]() The term "real-time strategy" was coined by Brett Sperry to market Dune II in the early 1990s. By contrast, in turn-based strategy (TBS) games, players take turns to play. ![]() Overall, this study has shown that hyperspectral drill core scanners can be used to characterise coal and non-destructively classify rank and lithotype.Real-time strategy ( RTS) is a subgenre of strategy video games that do not progress incrementally in turns, but allow all players to play simultaneously, in "real time". Among the less banded lithotypes, it was established that high liptinite content coals can be distinguished by their aliphatic spectral features in core samples. The variable spectral features related to composition were mapped onto the slabbed core surface, discriminating bright and dull bands and fusain lenses enabling the classification of coal lithotypes, regardless of rank. In addition to rank, trends in the magnitudes of the spectral features were influenced by maceral composition, particularly in low rank samples with abundant liptinite or inertinite group macerals. Other spectral features in the SWIR and MWIR regions also correlated with coal rank parameters. The ratio of the area of the aromatic absorption feature to that of the aliphatic absorption features, herein called Rank Spectral Index, displayed a strong linear correlation with coal rank parameters, such as vitrinite reflectance. The CH stretching fundamentals at 3280 nm correspond to the aromatic fraction of the coal, while the spectral region between 3380 nm and 3500 nm corresponds to the CH 2 and CH 3 stretching fundamentals occurring in the aliphatic fraction of the coal. The features occurring at 1910 nm in the SWIR region and 2940 nm in the MWIR region tended to disappear as rank increased these features arise from OH bonds related to structural water and hence correlate with the moisture content. The observed spectral features of the coals changed with increasing coalification. The spectral characteristics of the coals measured using these scanning systems were compared to those obtained using well-established spectroscopy techniques that operate in the same region of the electromagnetic spectrum, such as Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR) spectroscopy. ![]() The samples used in this study came from Australian basins of Permian and Jurassic ages. Commercially available hyperspectral drill core scanning systems in the Visible and Near-Infrared (VNIR), Short-Wave Infrared (SWIR) and Long-Wave Infrared (LWIR) regions, along with a handheld spectrometer for the Middle-Wave Infrared (MWIR) region, were used to characterise a rank suite of coal samples (0.45% to 1.76% Rr) with different preparations (slabbed surface, outer core and compressed powder pellets).
