Accident Site

The aim of this study has been to propose a new method for automatic rectification and stitching of the images taken on the accident site. The proposed method does not require any measurements to be performed on the accident site and thus it is frsjebalaee of measurement errors. The experimental investigation was performed in order to compare the vehicle trajectory estimation according to the yaw marks in the stitched image and the trajectory, reconstructed using the GPS data. The overall mean error of the trajectory reconstruction, produced by the method proposed in this paper was 0.086 m. It was only 0.18% comparing to the whole trajectory length.

In the paper a new method is presented to simulate the course of light output from organic light emitting device. The method uses optical transmission matrix to deal with multiple layers. To confirm the validity of our theories, a comparison of the theoretic analysis with testing results is given. The calculated curve consistented with the experimental value. By this methoed the Commission Internationale de L'Eclairage （CIE） coordinates of device were simulated. By adjusting the thickness of each layer in organic light emission diode (OLED) we obtained different CIE coordinates. When thickness becomes thicker the CIEX becomes bigger on the other hand CIEY become smaller.

The Absolute

A new method for the absolute determination of the quantum yield based on the trapping of fluorescence light within a cylinder is discussed. First the trapping probability of photons—which are emitted in transparent rods or fluid-filled tubes—is investigated theoretically. The studies are based on the extension of light governed by the laws of reflection and refraction. The effect of nonhomogeneous distribution of the centers of fluorescence light emission on the calculation procedures is taken into account. Then the adaptation of the theoretical results to a new practical method is shown. The quantum yield as a function of the exciting wavelength is determined in one experimental cycle. The discussion of the method is performed by measurements on fluorescein in aqueous solution. The results are compared to literature data. The conformity demonstrates the applicability of the new method.
