Abstract: When arrangements with a repeating working cycle such as, for example, in the case of engine test benches, are being controlled, resonances which have to be damped by the control system are often excited by the test specimen (for example an internal combustion engine) in the working range of the arrangement. The invention proposes for this purpose a control concept in which a modified actual value rist—mod is determined from a current actual value rist—akt of the control system and from a predicted imminent system-delay-free actual value on the basis of the actual value of a previous working cycle, and said modified actual value rist—mod is fed to the control system.

Abstract: The present invention provides recombinant poxviruses, such as vaccinia virus, that contain an integrated exogenous sequence, such as a foreign gene, encoding a prodrug converting polypeptide that can convert a prodrug to a drug that prevents virus replication or is otherwise toxic to the virus. The recombinant poxviruses can be suitable for use as vaccines. The invention also provides, among other things, methods of inhibiting virus replication, methods of vaccination and methods of treating vaccinated subjects showing signs or otherwise at risk for of vaccination-induced disease.

Abstract: A test stand arrangement includes at least one electric motor (4) connected to a test specimen for driving and/or loading the test specimen, and a control arrangement for the or each electric motor. In order to be able to create the connection of the drive train and vehicle simulation with the real, vehicle-specific combustion and dynamic behavior of the engine, at least one model for a multi-mass flywheel is implemented in the control arrangement, from which model at least a part of the control requirement for the or each electric motor is calculated and which model contains at least the two masses of the primary and secondary side of the multi-mass flywheel and a substitute model for the or each bow spring, and an algorithm is implemented in the control arrangement that analyzes the model for a multi-mass flywheel by means of an integrated time step method.

Abstract: A test stand assembly includes an electric machine (4) for driving and/or loading a test object (1), which is connected by a connecting shaft (2) having an adapter flange (3) to the electric machine (4). The assembly has a constant, predetermined moment of inertia, and the mass and the moment of inertia of the adapter flange (3) are selected in such a manner that the resonant frequency of the system formed of test object (1), adapter flange (3), connecting flange (2), and electric machine (4) for driving and/or loading the test object (1) lies between the idle frequency and the partial load frequency of the test object (1).
