“…In the papers that deal with fuels or wastes, laboratory tests were most commonly used-either with the use of standard procedures [4], with the application of typical equipment innovatively used for specific tests [1,2,7] or with the use of dedicated testing facilities, developed or tuned for the investigations that were performed [3,5,6,8]. The analysis of the test results was confirmed using already-known theoretical equations [1,3,4], experimentally identified dependencies (linear and non-linear regression) [1,3], advanced methods of picture analysis [2] and spectral analyses [6,8]. The comparison of developed models of investigated processes was supported with statistical analyses [3,7].…”
