The paper describes an initial approach adopted by the authors to create a system used for modelling of 3D environment. Data for a model is obtained by a 2D laser scanner measuring a distance of the real environment points and by the SPAN device showing information about scanner movement. The communication between the devices (scanner, GPS, INS) is based on different protocols, so data must be extracted...
The paper describes the potential of a 2D laser scanner and a very accurate SPAN (Synchronized Position Attitude Navigation) navigation combination in a mobile measurement platform constructed by our department. The laser scanner captures raw data of the environment and SPAN estimates the actual position. Thanks to the high level of exactness of cooperation of both of these devices it is possible...
The paper presents a methodological approach used by the authors in the process of design of a knowledge base for the domain related to measurement of different pavement characteristics. As the main representation formalism a rule is considered. Individual steps taken in the process of knowledge discovery in data are discussed. The process is demonstrated using limited sample data related to pavement...
Although thienopyridines attract attention because of their biological activities, they have not been used as ligands in coordination compounds. Thieno[2,3-b]pyridine was prepared by known procedures; by reduction of 2-nitrothiophene, and reaction of the resulting 2-thienyl ammonium salt with malondialdehyde tetramethylacetal in the presence of zinc chloride. The same procedure was used for the preparation...
