This is a backup place for abstract books of Szczyrk conferences “Chromatographic methods of investigating the organic compounds”, which were held many years until COVID pandemic. These events are very close to my heart. Below you can download all books in ZIP (PDF+DJVU), as well as browse individual files. 2005 2006 2007 2009 2010 2011…

An unit system based on binary multipliers and parameters of the universe Revision I – created on 1st October 2017 The creation of the SBI system has no serious aim. It is a result of a long spare time mental  entertainment. SBI can be used by programmers for fun (yes, it is binary!) or studied…

Investigating a number of the TLC chromatographic systems, full separation often occurs in several cases. A question appears here: which system should be considered to be the best, if selectivity is similar? The intuitive answer is to choose the system in which the spots are most equally spaced between themselves (for example RF = 0.25,…

Below you can find R and Matlab code snippets for DMA. It is a new unsupervised data exploration method concept, fitting directions by explaining structure of the majority of data objects, regardless of the distribution and variance of whole data set. Theory and algorithm is explained in (10.1016/j.chemolab.2016.03.005). R snippet centers data with l1median_BFGS, so…
