Abstract:
A layer system including a substrate and a layer is provided. The layer system has a hole at least in the layer, and wherein at least one recess is present in a surface of the layer in a vicinity around the hole or directly adjoining a boundary line of the hole.
Abstract:
A solar concentrator has frame members connected together to form a framework, and a flexible sheet attached to the framework such that the flexible sheet takes a loose shape and can flex in response to shaping forces exerted thereon. The sheet has a reflective surface located between the frame members. A shaping force system is operative, when activated, to exert the shaping forces on the sheet, the shaping forces configured to draw the sheet from the loose shape into a desired shape such that solar rays striking the reflective surface are focused on a target, and a solar energy receiver is attached to the framework at a location corresponding to the target. Thin wall tubing filled with pressurized air can provide strong light frame members. When the shaping force system is deactivated, the flexible sheet reverts substantially to the loose shape.
Abstract:
Recording and evaluating magnetic resonance signals of a functional magnetic resonance examination of a patient is provided. A region of the patient's brain is influenced during at least two time intervals. During the first time interval, the influencing takes place in accordance with a first way of stimulation and during a second time interval in accordance with a second way of stimulation, wherein the first and the second way of stimulation differ. While the at least two time intervals magnetic resonance signals are acquired from the region of the patient's brain by means of a pseudo-random stimulation sequence, the acquired magnetic resonance signals are evaluated.

Abstract:
There are a multiplicity of methods of making through-holes. In particular in the production of a multiplicity of film-cooling holes, as in gas turbine blades or combustion chamber elements, small time advantages are also important when making a hole. The method according to the invention, to make the hole close to the final contour in each case in sections in a top and a bottom region in order to then produce the final contour with other laser parameters, achieves time advantages.
Abstract:
A method and a computer system are disclosed for automatically generating a statistical vascular model of a patient group. In at least one embodiment, the method includes collecting specifying patient-related vascular coordinates models from a multiplicity of vascular landmark coordinates of vascular landmarks, centerline coordinates on vessel centerlines and vessel contour coordinates on vessel contour edge profiles; specifying body landmark coordinates of body landmarks; registering the vessel-related coordinates to patient-related registered vascular coordinates models; merging patient-related vascular parameter models to form at least one statistical vascular parameter model; specifying the statistical parameters thereof; and saving and/or outputting the at least one statistical vascular parameter model.
Abstract:
A device and method for exchanging data frames are disclosed. In one aspect, the device exchanges data between a WAN and one or more LAN segments in an optimized way leading to a better quality of experience for the user. The device comprises an interface exchanging data frames over an access network, at least a first and second subnet interface exchanging data frames and arranged for being coupled to a network, a memory storing classification rules, a classification agent extracting information from an incoming data frame and applying the rules to the extracted information to determine the interface via which the incoming data frame is to be forwarded, and a Quality of Service monitoring agent for retrieving Quality of Service information from the subnet interfaces and dynamically updating the classification rules according to the QoS information.
Abstract:
Conventionally coated components with film cooling holes are known, comprising a diffuser, extending through the layers into the substrate. According to the invention, the component is embodied such that the whole diffuser is largely arranged in the layer.
Abstract:
A method to grant a supplicant access to a data communication network and related devices is claimed. The supplicant is associated to a Medium Access Control address and is coupled to a port of an authenticator of the data communication network. The method includes: transmitting an authentication request by the authenticator to an authentication server being coupled thereto; making by the authentication server an authentication decision based upon predefined rules and conditions; and transmitting by the authentication server to the authenticator an authentication reply that comprises a result of the authentication decision.
Abstract:
A method for producing a nanostructured, in particular a ceramic-like functional coating on a substrate is described. To that end, using at least one plasma source, a pulsed plasma is produced with which a matrix phase and at least one nano-scale interstitial phase embedded in it are deposited on the substrate via a material input. Preferably a plurality of pulsed plasma sources that are time-correlated or synchronized with each other are used. Also proposed is a nanostructured functional coating, in particular one producible by this method, which is free of chlorine and/or sulfur, and which contains at least one metal and/or at least one element selected from the group oxygen, hydrogen, nitrogen, carbon, helium, argon or neon.
