378 65

Abstract:

Use of an adaptive radiation therapy framework includes determination of a radiation beam size, radiation beam shape, and radiation beam position for delivering at least a portion of a prescribed radiation dose to a target volume based on first image data of a patient, and selection of one radiation therapy process from an available first process and second process. The first radiation therapy process comprises acquisition of two dimensional image data of the patient, determination of a position offset based on the two-dimensional image data and on the first image data, and movement of the patient based on the position offset. The second radiation therapy process comprises acquisition of three-dimensional image data of the patient, determination of a second position offset based on the three-dimensional image data and on the first image data, and movement of the patient based on the second position offset.

Abstract:

Techniques for using traceroute with tunnels and cloud-based systems for determining measures of network performance are presented. Systems and methods include requesting a trace to a destination with a signature inserted into a trace packet; receiving a response to the trace packet; when the response does not include tunnel info, providing details in the response to a service where the details include parameters associated with a service path between the client and the destination; and, when the response includes tunnel info, segmenting the service path into a plurality of legs, causing a trace for each of the plurality of legs, and aggregating details for each of the plurality of legs based on the causing.

International Classification:

H04L 29/06

Abstract:

Systems and methods include establishing a control channel of a tunnel utilizing a first encryption technique, wherein the tunnel is between a local node including one or more processors and a remote node, and wherein the control channel includes a session identifier; establishing a data channel of the tunnel utilizing a second encryption technique, wherein the data tunnel is bound to the control channel based on the session identifier; performing, over the control channel, device authentication and user authentication of one or more users associated with the remote node, wherein each of the one or more users includes a user identifier; and, subsequent to the device authentication and the user authentication, exchanging data packets over the data channel with each data packet including a corresponding user identifier. The first encryption technique can be one of TLS and SSL, and the second encryption technique can be one of TLS and DTLS.

The generating of the search facets is based on a user profile associated with the user and one or more similar user profiles. The machine receives an identifier of the user from a client device. The machine causes a display of one or more selectable identifiers of the one or more search facets in a user interface of the client device associated with the user. The machine receives, from the client device, an indication of a selection of the one or more selectable identifiers of the one or more search facets. The machine causes a display of one or more job descriptions in the user interface based on a search performed using the one or more search facets.
