Abstract: The present embodiments relate to systems and methods for automatic sign in upon account signup. Particularly, the present embodiments can utilize a federated login approach for automatic sign in upon account signup for a cloud infrastructure. Specifically, the signup and sign in service (also known as SOUP) and an identity provider portal can be configured such that the nodes are aware of each other as Security Assertion Markup Language (SAML) partners. After new account registration, the signup service can redirect the user browser to a cloud infrastructure console to start with a federated login flow, where a sign in service can issue a SAML authentication request, and redirects it to signup service. Responsive to validating the browser using a SAML authentication process, the browser can be automatically signed into the new account and allowed access the account relating to the cloud infrastructure service.

Abstract: Techniques for clustering sensor data are discussed herein. Sensors of a vehicle may detect data points in an environment. Clustering techniques can be used in a vehicle safety system to determine connection information between the data points. Further, the machine learned model can be trained to output motion data representing velocity data or a cluster association score. The connection information and/or motion data can be used by a vehicle computing device to detect objects in an environment and/or to control operation of a vehicle.

Abstract: Hypoxia-inducible factor 1? protein or a detection reagent thereof can be used in depression recurrence diagnosis. It has been demonstrated that the specificity of hypoxia inducible factor 1? protein increases in the serum of patients with depression recurrence after interventions. As such, hypoxia inducible factor 1? protein can be used as a peripheral blood biomarker for the early screening or differentia diagnosis of depression recurrence, and for post-intervention assessment of treatment efficacy of patients with depression.

Abstract: This disclosure describes techniques for using radar cross-section (RCS) data to classify objects detected by autonomous vehicles within driving environments. In some examples, the variance of the RCS data associated with an object may be evaluated to determine signal interference caused by multipath fading. The variance of the RCS data may be used to classify the object and to determine whether the autonomous vehicle can safely drive over the object. For instance, objects such as manhole covers, storm drains, and expansion joints may provide a significant radar signal, but low RCS variance indicating that they can be driven over by the vehicle. Based on the classification of the object, the autonomous vehicle may determine a trajectory around the object or directly over the object.

Abstract: A two-dimensional exit pupil expansion method for waveguide display based on polarization volume gratings (PVGs) is provided. Based on the polarized diffraction properties of the PVGs as waveguide coupling elements, a light beam from a microimage source system is introduced into and then propagates in a waveguide medium. By a composite PVG structure, a light field of a transmitted image is subjected to two-dimensional exit pupil expansion and emission, and finally incident into human eyes to achieve waveguide augmented reality imaging.

Abstract: Techniques for verifying a reliability of map data are discussed herein. In some examples, map data can be used by a vehicle, such as an autonomous vehicle, to traverse an environment. Sensor data (e.g., image data, lidar data, etc.) can be received from a sensor associated with a vehicle and may be used to generate an estimated map and confidence values associated with the estimated map. When the sensor data is image data, images data from multiple perspectives or different time instances may be combined to generate the estimated map. The estimated map may be compared to a stored map or to a proposed vehicle trajectory or corridor to determine a reliability of the stored map data.

Abstract: Techniques are discussed herein for analyzing radar data to determine that radar noise from one or more target detections potentially conceals additional objects near the target detection. Determining whether an object may be concealed can be based at least in part on a radar noise level based on a target detection, as well as distributions of radar cross sections and/or doppler data associated with particular object types. For a location near a target detection, a radar system may determine estimated noise levels, and compare the estimated noise levels to radar cross section probabilities associated with object types to determine the likelihood that an object of the object type could be concealed at the location. Based on the analysis, the system may determine a vehicle trajectory or otherwise may control a vehicle based on the likelihood that an object may be concealed at the location.

Then, the computer device determines the association attribute and first target information corresponding to the association attribute, adds, to a packet for accessing a target resource, the association attribute and the first target information corresponding to the association attribute, and sends the packet, where the packet further includes at least the first indication information.

Abstract: Various methods and systems are provided for autonomous orchestration of secrets renewal and distribution. A secrets management service (“SMS”) can be utilized to store, renew and distribute secrets in a distributed computing environment. The secrets are initially deployed, after which, SMS can automatically renew the secrets according to a specified rollover policy, and polling agents can fetch updates from SMS. In various embodiments, SMS can autonomously rollover client certificates for authentication of users who access a security critical service, autonomously rollover storage account keys, track delivery of updated secrets to secrets recipients, deliver secrets using a secure blob, and/or facilitate autonomous rollover using secrets staging. In some embodiments, a service is pinned to the path where the service's secrets are stored. In this manner, secrets can be automatically renewed without any manual orchestration and/or the need to redeploy services.

Abstract: A SIS identification method of reversible recovery fault-oriented workshop key manufacturing resources is that based on SIS model in the infectious disease research theory, the workpieces and manufacturing resources required in a production order are linked together through database technology to establish a discrete production workshop manufacturing network. The SIS model is configured to solve a change of the number of bottlenecks of other manufacturing resources caused by the initial fault manufacturing resources over time. The weighted result of a peak number of bottleneck resources and its time to reach the peak is marked to determine the importance of the initial fault manufacturing resources. Through the sorting of importance, the key manufacturing resource nodes in the discrete workshop are finally selected. The invention sorts out other key manufacturing resources that need to pay attention in production management in the manufacturing workshop to plan in advance and to improve the efficiency.

Abstract: Techniques relating to monitoring map consistency are described. In an example, a monitoring component associated with a vehicle can receive sensor data associated with an environment in which the vehicle is positioned.

The monitoring component can then compare first information associated with a stored map of the environment with second information associated with the estimated map to determine whether the estimated map and the stored map are consistent. Component(s) associated with the vehicle can then control the object based at least in part on results of the comparing.
