Abstract: A computer-implemented method for positioning technical elements in a space, wherein the elements each have an element work area, where the method includes a) providing the geometry of the space via a space model, b) determining a set of possible element positions for positioning elements from the space model taking into account predetermined positioning rules for the space, c) ascertaining the number of elements for the space via a model based on machine learning, d) determining a set of element arrangements with permutations for elements at each possible element position, and e) determining the element arrangement with the smallest ratio of the number of elements for the space and the total element work area from the ascertained set of element arrangements.

Abstract: A system and method for the randomization of packet headers is disclosed. A controller is used to provide random values, also referred to as nonces, that replace the source and destination addresses that typically appear in a packet header. The controller also provides routing rules to the switches and routers in the network that allow these devices to properly route packets, even though the source and destination addresses are not present. In some embodiments, network devices that support software-defined networking (SDN) are employed. The number of times that a particular nonce is used may be variable. In some embodiments, a nonce is used for exactly one packet header. In this way, packets may traverse a network using nonces in place of actual source and destination addresses. Because the nonces are changed periodically, detection of traffic patterns is made significantly more difficult.

Abstract: A structure in a substrate for the manufacturing of a semiconductor device, wherein a first material and at least one second material are to be etched by at least one etching medium, wherein the at least one second material has a higher etch rate for the at least one etching medium relative to the first material. The at least one second material occupies a space which is at least at one side adjacent to the first material so that an additional etching access to the first material is prepared when at least one etching medium etches the first and the second material.

Abstract: A computer implemented method, an apparatus, and a computer usable program product are provided for configuring and modeling server connection and deployment information in an enterprise tooling environment. A software model is provided that comprises a connections object, which includes a plurality of connection objects and deploy spec objects. Each of the connection objects is specific to a backend server type. A deploy controller is provided at run time to examine the connections object for a connection object. A backend resource manager is loaded for a specific application server. If a connection object is present, the backend resource manager loads a connection interpreter, which transforms development time connection information in the connection object to the run time connection information in corresponding deploy spec object and connection factory spec object. The backend resource manager then writes the deployment information to the configurations files of the application server.
