Forensic olfactorics and its future
Hladíková, Dominika ; Dvořák, Marek (advisor) ; Krupička, Jiří (referee)
1 ABSTRACT Forensic olfactorics and its future Forensic olfactorics is one of the methods of criminal odourology. Olfactorics uses the sense of smell of a specially trained dog to examine and identify odours. The most important type of dog scent work is the individual identification method. This method arose from the development of service cynology and has undergone considerable development over the years. There are extensive scientific studies dealing with the function of the dog's sense of smell, which show that there is as of yet no other device so developed that is capable of identifying and comparing human scent. The thesis also discusses the training of service dogs for scent work as well as the process of olfactory comparison, from locating scent traces, to securing them, to the actual comparison of two scent conserves. The legal framework for the use of olfactory comparison as part of evidence in criminal proceedings is also presented. In spite of the above, opinions persist within the judicial practice, especially that of the Czech Constitutional Court, that the evidence provided by the scent analysis is only supporting evidence and cannot be the main evidence. The thesis seeks to identify possible reasons for these opinions as well as to outline possible solutions that could enable the method of...

Criminalistic Odorology
Vinšová, Denisa ; Krupička, Jiří (advisor) ; Dvořák, Marek (referee)
Criminalistic Odorology Abstract This thesis is focused on the scientific field of criminalistic odorology with a focus on criminalistic olfactorics. The main topic of this thesis is to find out on what principles this scientific field works and to map its system of functioning and using in practice. This thesis is divided into about 5 main chapters or topics that it deals with. These are the history of the development of criminal olfaction, the definition and description of criminal odour science, the theoretical basis for its use in practice such as the analysis of smell and olfaction and finally its use in practice. The last part focuses directly on the method of scent identification and its performance and use in court as evidence. The first chapter deals with the history and development of the use of the dog by man, first as his protector, then protector of his property, companion and finally scent biodetector in the service of the police. The second chapter defines what criminal odor science is and divides it into two parts, olfactorics and olfactronics, which it then describes as subjective and objective methods of examining scent. In the third chapter he discusses smell and olfaction and their biological, physical and chemical basis. The fourth chapter describes the use of dogs as live odour...
