Abstract: Devices, systems, computer program products and computer implemented methods are provided for dynamically assessing a moving object from a sequence of consecutive volumetric image frames of such object, which images are timely separated by a certain time interval, by: identifying in at least one image of the sequence the object of interest; segmenting the object to identify object contour; propagating the object contour as identified to other images of the sequence; and performing dynamic analysis of the object based on the object contour as propagated.

Abstract: A method is provided for simulating two-dimensional (2D) shadow images of an object (particularly an asymmetrical object), which comprises: a) obtaining a representation of the surface of said object; b) inputting a perspective viewing direction defining a virtual path line; c) calculating intersections between the virtual path line and the surface of the object; d) calculating the distance between couples of consecutive intersections; e) calculating simulated beam intensity attenuation between such couples of consecutive intersections from an input parameter related to the attenuation coefficient of the object and the distance as calculated in d); and f) displaying the simulated beam intensity attenuation as pixel brightness in a grey or color scale in the form of a shadow image. A corresponding device, system and computer program are also disclosed.

Abstract: A broker service facilitates the provision of health-related information to an interested third party. The broker enters into an agreement with one or more health care institutions to obtain at least some access to health-related information stored on a server. In response to a request by the third party, the broker may construct a search filter to find relevant information stored on the server. The broker then may forward at least some of the results to the third party. The broker may install a plug-in software program on the server to facilitate access to the health-related information and/or limit the information based on local health care regulations.

Abstract: Modified polyvinyl acetals are prepared by saponification of 1-alkylvinyl acetate-vinyl acetate copolymers, which contain 1-alkylvinyl acetate/vinyl acetate in a weight ratio of 1/99-40/60 and subsequent acetalization the saponification products containing at least 80% units of vinyl alcohol and 1-alkyl vinyl alcohol with one or more aliphatic aldehydes with 1-6 C atoms under acid catalysis in an aqueous and/or organic medium; as well as to a method for the manufacture and the use thereof, especially in printing inks.
