Abstract: A method for simulating object flows which move in an area, the method being based on cellular automata is improved in such a way that the simulation depicts the object flows as realistically as possible. It is further proposed that based on a desired speed of an object, the speed is lowered as the object density increases using a brake class table having a plurality of brake classes in such a way that a relationship between the object density and the object speed results according to a fundamental diagram. Thus, conventional methods for simulation of object flows are improved. The method is suitable in particular for flows of persons.

Abstract: A method and apparatus for the simulation of object streams moving in an area based on cellular state machines can be improved such that the simulation maps the object streams as realistically as possible. It is also being proposed that the norm of a difference vector having direction of movement of an object and the direction of movement of a neighboring object is also incorporated as a weighting factor in a calculation of the object potential. Thus, conventional methods for the simulation of object streams are improved. The method and apparatus is particularly suitable for streams of people.

Abstract: A process is disclosed for the electronic recording of an image of the surface of an object, which image can be displayed as a function G(x, y), wherein x and y are the coordinates of a respective image point of the image and G designates its gray value, wherein the object is recorded sequentially over different times ti, where ti+1>ti, from different perspectives as function Gi in order to form the total image G from the individual images Gi(x, y) such as when rolling a finger for recording a fingerprint, wherein portions are cut out of the individual images and joined together depending on the respective recorded view, wherein a curved intersection line is determined for defining the portions of every image aside from the first image Gi by comparison with the image content of the previously recorded or assembled image Gi−1, wherein the portion of the image Gi−1 is defined by this curved intersection line and the corresponding portion of the image Gi is subsequently added to this intersec

Abstract: The invention is directed to an arrangement for recording highly resolved two-dimensional images with a moving image sensor and to a method for generating optimized scan patterns for image recording systems which scan in two dimensions. The object of the invention is to find a novel possibility for recording high-resolution images with resolution-increasing two-dimensional sensor movement which achieves in a simple manner an appreciable reduction in image interference occurring when the object moves during the scanning movement of the image sensor. According to the invention, this object is met in that a scan pattern is provided for the sensor movement in a selected scan raster with n scan positions in x-direction and m scan positions in y-direction, which scan pattern has a fixed sequence of scan positions in the form of scan numbers, wherein there is a time interval of at least two scanning steps for spatially adjacent scan positions in x-direction and y-direction.

Abstract: Novel hybrid interferons are produced which are derived from lymphoblastoid interferons .alpha.-2 and .alpha.-3 belonging to the interferon .alpha.B and .alpha.D groups, respectively. The novel hybrid interferons possess valuable antiviral and antiproliferative properties.
