A method for modeling the image point motion as function of the degree of zoom and focus is described and evaluated. The method requires that the camera can be translated towards a frontoparallel grid of calibration marks. The evaluation shows that, for a translation span of 2 meters, a zoom range from 10 to 96 millimeter, and for focus settings between 1(More)
A 32-yr-old white North American male resident of Norway presented with an asymptomatic radiolucency first identified 3 yr after the removal of an impacted mandibular right third molar in Southern California 16 yr previously. Surgical exploration revealed an intraosseous cavity filled with a black, homogeneous, gelatinous substance thought to be foreign(More)
In a screening programme nine Danish meat smokehouses were randomly selected for measurements on concentration of airborne polycyclic aromatic hydrocarbons (PAH). A total of 23 stationary air samples were collected during the entire working period of the kiln either above the kiln doors or approximately 2 m in front of the kiln doors (i.e. total exposure on(More)
The three-dimensional structure of the crystalline surface layer (S-layer) of Wolinella recta ATCC 33238T, a gram-negative, anaerobic periodontopathogen, was determined to 3.8 nm resolution by electron microscopy and digital image processing. The S-layer protein is closely associated with the outer bacterial membrane, and shows p6 symmetry with lattice(More)
A high-performance liquid chromatography/fluorescence method using multiple wavelength shift for simultaneous quantification of different PAH compounds was developed. The new method was superior to the methods of DONG and GREENBERG [J. Liquid Chromatogr. 11, 1887-1905 (1988)] and WISE et al. [Polycyclic aromat. Hydrocarb. (in press)] with respect to(More)
This paper describes a procedure to calibrate a two degree of freedom robot, which is able to translate and rotate a turntable on which a camera is mounted. The calibration enables the transformation of the coordinates of an image point, observed from any known position of the robot, to a 3D straight line, speciied in a world coordinate system.
