Abstract: To improve the efficiency of bounding volumes in a hardware based ray tracer, we employ a sheared axis-aligned bounding box to approximate an oriented bounding box typically defined by rotations. To achieve this, the bounding volume hierarchy builder shears an axis-aligned box to fit tightly around its enclosed oriented geometry in top level or bottom level space, then computes the inverse shear transform. The bounds are still stored as axis-aligned boxes in memory, now defined in the new sheared coordinate system, along with the derived parameters to transform a ray into the sheared coordinate system before testing intersection with the boxes. The ray-bounding volume intersection test is performed as usual, just in the new sheared coordinate system.

Abstract: A vapor delivery needle is provided that may include any of a number of features. One feature of the energy delivery probe is that it can apply condensable vapor energy to tissue, such as a prostrate, to shrink, damage, or denature tissues of the prostate. Methods associated with use of the energy delivery probe are also covered.

Abstract: A method may include a processing system assigning samples of network traffic data to positions in a list, where each of the samples is assigned a cluster identifier corresponding to the respective position, and traversing the list, where for each position, the processing system: increments an order indicator, and when the cluster identifier is not less than the order indicator, computes a distance between a sample assigned to the position and other samples, records a cluster identifier of another sample when a distance between the sample and the other sample is less than a threshold distance, and assigns a minimum cluster identifier that is recorded to all of the samples with cluster identifiers that are recorded. The processing system may determine clusters from cluster identifiers in the list after the traversing and identify at least one cluster as representing anomalous network traffic data.

Abstract: A processing system having at least one processor may obtain domain name system (DNS) traffic records of a DNS platform, the DNS traffic records associated with a source device having a first status and that is submitting DNS queries, where a first-tier DNS authoritative server of the DNS platform is configured to forward the DNS queries from the source device to at least a first second-tier DNS authoritative server of the DNS platform designated for the first status.
