The features of the expert study of traces from the effects of foreign objects on the inner surfaces of the cylinder mechanisms are considered. With the trasological examination of locks, most experts after examining the external and internal surfaces of the cylinder mechanisms of locks, unlocked by various types of keys, falsified or selected keys, ambiguously understand the mechanism of their trace formation, which can sometimes lead to a false conclusion. The purpose of the work is to present the results of the investigation of the mechanism of trace formation and localization of signs of exposure of foreign objects (lock pick, selected or fake keys) on the internal surfaces of the cylinder mechanisms of locks and recommendations to forensic experts in drawing conclusions during the course of the Trasological research. The mechanism of trace formation is considered, the characteristic and classification of traces of exposure to foreign objects are provided (lock pick, selected or fake keys). Groups of lock pick are identified, which are most often found in the Commission of criminal offenses, for their further research. A number of experimental studies have been carried out to study and analyze the mechanism of trace formation, as well as to localize the signs of influence of certain groups of lock pick on the internal surfaces of the cylinder mechanisms of the lock. The progress of the experimental studies has been described in stages. The results of the research on the opening of the cylinder mechanisms of locks are presented with various types of lock pick, depending on their design features. The illustrations explain the conditions for the location of traces on the relevant parts of the cylinder mechanisms of locks from the influence of the respective groups of lock pick. The results of an experimental study are summarized and conclusions are made on the possible conditions for the mechanism of trace formation. Recommendations to judicial experts on the formulation of conclusions in the course of trasological studies of cylinder locking mechanisms are proposed.

In this paper, the phenomena of hysteretic behaviour of friction force observed during experiments are discussed. On the basis of experimental and theoretical analyses, we argue that such behaviour can be considered as a representation of the system dynamics. According to this approach, a classification of friction models, with respect to their sensitivity on the system motion characteristic, is introduced. General friction modelling of the phenomena accompanying dry friction and a simple yet effective approach to capture the hysteretic effect are proposed. Finally, the experimental results are compared with the numerical simulations for the proposed friction model.

Though vague phenomena have been studied extensively for many decades, it is only in recent years that researchers sought the support of quantitative data. This chapter highlights and discusses the insights that experimental methods brought to the study of vagueness. One area focused on are ‘borderline contradictions’, that is, sentences like ‘She is neither tall nor not tall’ that are contradictory when analysed in classical logic, but are actually acceptable as descriptions of borderline cases. The flourishing of theories and experimental studies that borderline contradictions have led to are examined closely. Beyond this illustrative case, an overview of recent studies that concern the classification of types of vagueness, the use of numbers, rounding, number modification, and the general pragmatic status of vagueness is provided.
