Abstract: A system is provided for attaching a layer of a metal to other layers in a material stack-up using a metal mechanical fastener that does not allow for direct contact between the fastener and the metal layer, thereby neutralizing any galvanic reaction between the metal sheet and the fastener and avoiding corrosion. The metal layer may be any of several metals, including magnesium. The fastener is a rivet, a screw or a bolt. The disclosed inventive concept uses an insulating layer to insulate the magnesium layer. In one embodiment, a layer of a thin metal is formed over the insulating layer. Where the fastener is a rivet and the metal is magnesium, the insulating layer and thin metal provide a barrier between the magnesium layer and the rivet prongs following rivet insertion, thus isolating the rivet. The system enables a greater application of fastener joining, particularly with magnesium and mixed material joining.

Abstract: A computer-implemented method that includes monitoring execution of program code by first and second processor components. A computing system detects that a trigger condition is satisfied by: i) identifying an operand in a portion of the program code; or ii) determining that a current time of a clock of the computing system indicates a predefined time value. The operand and the predefined time value are used to initiate trace events. When the trigger condition is satisfied the system initiates trace events that generate trace data identifying respective hardware events occurring across the computing system. The system uses the trace data to generate a correlated set of trace data. The correlated trace data indicates a time ordered sequence of the respective hardware events. The system uses the correlated set of trace data to analyze performance of the executing program code.

Abstract: A cloud worker management system has a worker management unit. The worker management unit manages a plurality of cloud workers. The worker management unit dynamically allocates and manages deployment of the cloud workers to a plurality of servers. A request handling unit communicates with the worker management unit. The request handling unit receives job request, creates a job data structure object for the job request and forwards the job request with the job data structure object to an available cloud worker. A user interface allows users of the system to view and edit job statutes; track jobs; monitor status, load and operating parameters of each cloud worker; set and change rules for cloud worker and server deployments, and perform analytics on job results.

Abstract: Provided are methods for growing a plant under certain stressed conditions that alter the morphology of the plant. In certain aspects, however, although the plant is altered and may be undesirable for commercial purposed, the plant still produces an adequate number of seeds for breeding purposes. Further, because plants may be smaller in size, they can be grown at higher densities, allowing the production of large populations of plants to be brought under controlled conditions which can exclude pollinating insects and thus increase the genetic purity achievable in a breeding program.

Abstract: A system is disclosed for providing low data rate broadcast services. Different types of broadcast packets are detected among data packets received an external network. The different types broadcast packets contain different a different broadcast content. When a particular type of broadcast packet is detected, a transmit data rate is selected and Walsh codes are assigned for achieving the transmit data rate. Data packets corresponding to the broadcast packets are compressed, and at least one RLC block containing the compressed data packets is created. The RLC blocks are transmitted from a satellite using the assigned Walsh codes.

Abstract: Methods of secure resource authorization for external identities using remote principal objects are performed by systems and devices. An external entity creates a user group and defines entitlements to an owning entity's secure resource as a set of permissions for the group. An immutable access template with the permissions and an access policy for the secure resource are provided to the owning entity for approval. On approval, a remote principal object is created in the owner directory according to the permissions and access policy. A remote principal that is a group member requests access via an interface to the owner domain using external domain credentials. The identity of the remote principal is verified against the remote principal object by a token service. Verification causes generation and issuance of a token, with the enumerated entitlements, to the remote principal interface affecting a redirect for access to the secure resource.
