Abstract: This description provides an autonomous or semi-autonomous excavation vehicle that is capable of navigating through a dig site and carrying an excavation routine using a system of sensors physically mounted to the excavation vehicle. The sensors collect one or more of spatial, imaging, measurement, and location data representing the status of the excavation vehicle and its surrounding environment. Based on the collected data, the excavation vehicle executes instructions to perform an excavation routine by excavating earth from a hole using an excavation tool positioned at a single location within the site. The excavation vehicle is also able to carry out numerous other tasks, such as checking the volume of excavated earth in an excavation tool, navigating the excavation vehicle over a distance while continuously excavating earth from a below surface depth, and preparing a digital terrain model of the site as part of a process for creating the excavation routine.

Abstract: Disclosed herein is a technique for implementing a framework that enables application developers to enhance their applications with dynamic adjustment capabilities. Specifically, the framework, when utilized by an application on a mobile computing device that implements the framework, can enable the application to establish predictive models that can be used to identify meaningful behavioral patterns of an individual who uses the application. In turn, the predictive models can be used to preempt the individual's actions and provide an enhanced overall user experience. The framework is configured to interface with other software entities on the mobile computing device that conduct various analyses to identify appropriate times for the application to manage and update its predictive models. Such appropriate times can include, for example, identified periods of time where the individual is not operating the mobile computing device, as well as recognized conditions where power consumption is not a concern.

Abstract: Systems and methods for calculating uplink pathloss in a wireless local area network are provided. Uplink pathloss between an access point and client device operating in the wireless local area network can be calculated based on determining an effective maximum transmit power. Based on the effective maximum transmit power, and known uplink power headroom, a current transmit power of the client device can be determined. Based on the current transmit power of the client device, uplink pathloss can be determined. If the operating conditions and/or characteristics of the client device and/or wireless local area network change, the uplink pathloss may be re-evaluated.

Abstract: Approaches for ensuring a file operation is not performed in a malicious manner. Upon being instructed to perform the file operation on a file, a profile for the file is obtained. The profile is data that is signed by a digital signature and identifies a set of resources which said file requires. The profile associated with a particular file may be obtained in a variety of different ways. The file operation is performed in a virtual machine that lacks access to resources of the device or of a network except for those resources identified in the profile.

Abstract: In various embodiments, methods and systems for language scaling a natural language processing system (NLPS) are provided. A database schema of a database is accessed. The database schema includes entities that are defined in a query natural language different from an NLPS natural language upon which NLPS components are built. The entities are communicated to a machine translation service and top translations. A translated database schema model is generated based on the entities and translations. When a query associated with the query natural language and the database schema is received, a query translation is generated. The query translation comprises selectively translated portions of the query based on a selective translation mechanism that includes accessing the machine translation service to translate selected portions of the query. The selected portions are selected based on the translated database schema. The query translation is executed on the NLPS components to identify query results.

Abstract: According to examples of present disclosure, a network device may group a first subset of client devices for beamforming transmissions using multi-user multiple-input multiple-output (MU-MIMO), and also group a second subset of client devices associated with the two or more basic service sets for simultaneous data transmission using multi-user orthogonal frequency-division multiple access (MU-OFDMA). The subset of client devices within the same group may be associated with different basic service sets.

Abstract: Methods, systems, and computer program products are described herein for minimizing the downtime for nodes in a network-accessible server set. The downtime may be minimized by determining an optimal timeout value for which a fabric controller waits to perform a recovery action. The optimal timeout value may be determined for each cluster in the network-accessible server set. The optimal timeout value advantageously reduces the overall downtime for customer workloads running on a node for which contact has been lost. The optimal timeout value for each cluster may be based on a predictive model based on the observed historical patterns of the nodes within that cluster. In the event that an optimal timeout value is not determined for a particular cluster (e.g., due to a lack of observed historical patterns), the fabric controller may fall back to a less than optimal timeout value.

Abstract: A test platform provides modular test automation. The modular test automation may include defining modular segments of a test configuration, and testing an Application Under Test (“AUT”) based on the modular segments. The test configuration may define a specific flow or execution ordering for the modular segments. The flow may be changed by reordering the segments, modularly adding new segments anywhere in the flow, removing segments, modifying individual segments without affecting other segments, defining a particular segment once and reusing the particular segment in two or more different test configurations, and/or carrying over a change made to the particular segment in a first test configuration to the particular segment of a second test configuration automatically. The modular test automation may also include modularly selecting a set of nodes for testing the AUT according to the modular segments of the flow.

Abstract: Examples described herein include systems and methods for providing on-demand access to a restricted resource of a user device. An example method can include generating a profile that specifies a restricted resource and one or more conditions for that resource to be de-restricted. The profile can be sent to, and utilized by, an agent application executing on the user device. The agent application can determine that a user is requesting de-restriction of a resource and determine whether all applicable conditions are met. If the conditions are met, the agent application can de-restrict the resource. After the resource is used, the agent application can report details of the use to an administrator or management server.

The IoT file share server can partition the update file into a plurality of file chunks to be sent to the IoT device, each of which can include a portion of the update file, and the portion can be of the file chunk size.

Abstract: A nonreciprocal device includes a waveguide through which waves at a first frequency propagate with a first wavevector and with a second wavevector in a direction opposite to the first wavevector; a frequency-dependent device that operates within a frequency range and modifies the waves through the waveguide in a way that is dependent on the first frequency; and a set of couplers to couple the waveguide and the frequency-dependent device. Coupling rates of the set of couplers are modulated to enable nonreciprocal coupling, with respect to the frequency-dependent device, of the first wavevector compared to the second wavevector.

Abstract: The present disclosure is generally directed a data processing system for authenticating packetized audio signals in a voice activated computer network environment. The data processing system can improve the efficiency and effectiveness of auditory data packet transmission over one or more computer networks by, for example, disabling malicious transmissions prior to their transmission across the network. The present solution can also improve computational efficiency by disabling remote computer processes possibly affected by or caused by the malicious audio signal transmissions. By disabling the transmission of malicious audio signals, the system can reduce bandwidth utilization by not transmitting the data packets carrying the malicious audio signal across the networks.
