Abstract: A coding efficiency improvement is achieved by performing bit-plane coding in a manner so that coefficient groups for which the set of coded bit-planes is predictively signaled in the datastream, are grouped in two group sets and if a signal is spent in the datastream which signals, for a group set, whether the set of coded bit-planes of all coefficient groups of the respective group set are empty, i.e. all coefficients within the respective group sets are insignificant. In accordance with another aspect, a coding efficiency improvement is achieved by providing bit-plane coding with group-set-wise insignificant signalization according to the first aspect as a coding option alternative relative to the signalization for group sets for which it is signaled that there is no coded prediction residual for the coded bit-planes for the claim groups within the respective group set.

Abstract: Two-dimensional aerial images and other geo-spatial information are processed to produce land classification data, vector data and attribute data for buildings found within the images. This data is stored upon a server computer within shape files, and also stored are source code scripts describing how to reconstruct a type of building along with compiled versions of the scripts. A software game or simulator executes upon a client computer in which an avatar moves within a landscape. A classifier classifies a type of building in the shape file to execute the appropriate script. Depending upon its location, a scene composer downloads a shape file and a compiled script is executed in order to reconstruct any number of buildings in the vicinity of the avatar. The script produces a three-dimensional textured mesh which is then rendered upon a screen of the client computer to display a two-dimensional representation of the building.

The implant can be covered with newly created bile duct epithelium, thereby creating a new bile duct from body cells. The implant can be removed after completion of creation of the new bile duct. So, the implant as suitable as a temporary implant. The implant can be used for surgery, such as surgery of gall bladder, bile duct and/or liver, e.g. gall bladder removal, hepatobiliary malignancy surgery or liver transplantation.

A first body half comprises a first inside peripheral surface half which lies on a spherical surface and is closed, in the circumferential direction, and a second body half which comprises the socket opening, at least one slot extending axially and a second inside peripheral surface half which is closed in the circumferential direction, or closed apart from the slot. The second body half is designed such that the second inside peripheral surface half lies outside the spherical surface at least an axial distance away from the transition zone.

Abstract: Evaluation of security of a communication system. The security of the communication system is continuously monitored and the result of this assessment is indicated. In particular, characteristic security information provided by a communication partner may be continuously received and evaluated for determining the security status. In this way, a change of the security status can be immediately recognized. Thus, a transmission of sensible or confidential data over an insecure communication network can be avoided.

Abstract: The invention having functional vertical disposable reaction systems having a vertically mounted semipermeable membrane for sample preparation, chemical reactions, dialysis, enzymatic/microbiological fermentation, multistage processes, in vitro protein biosynthesis on a laboratory scale, formed from a base body and an exchangeable lid having different functions. For exchange across the membrane, the system is placed vertically into an outer volume consisting of gas, liquid or solid constituents. The system consists of a dimensionally stable base body and a liquid-tight lid having a functional support going toward the base of the base body, the dimensionally stable base body forming at least one noncapillary reaction space as inner volume with at least one semipermeable membrane as lateral wall. The high flexibility in use results from the combination of variants of the base bodies with different lid variants for different areas of use.
