Abstract: An agitator for vibrating a drill string includes an agitator housing, a rotor and an agitation mass. The drill string has a central axis. The rotor is coupled to the agitator housing and being rotatable about an agitator axis. The agitation mass is coupled to the rotor and is rotatable about the agitator axis. During rotation, a center of mass of the agitation mass is spaced apart from the agitator axis to cause deflection of the agitator axis relative to the central axis to produce vibration in the drill string.

Abstract: Systems and methods are provided for sending and receiving encrypted submessages. Messages could be partitioned into a plurality of submessages based on the content of a message, and such submessages could be individually encrypted and sent over a network. The partitioning could be based on various standards and/or heuristics. In the sending process, submessages could be designated to travel over different networks and networks of different types. Such submessages could then be received and reassembled in spite containing overlapping content with respect to each other, having to contend with copies of submessages, and having accompanying related content (e.g., advertisements) and non-related content (e.g., random bits). Moreover, the sending process could also be performed in real time or in a batched manner, depending on the implementation.

Abstract: In some implementations, a system may monitor session data associated with a first module and a second module of a platform. The system may determine a rate of communication between the first module and the second module based on the session data. The system may determine, using an optimization model, a co-location score associated with the first module and the second module based on the rate of communication, wherein the co-location score indicates an impact of co-location of the first module and the second module. The system may determine that the co-location score satisfies a co-location score threshold associated with an improvement to an operation of the platform. The system may perform an action associated with co-locating the first module and the second module.

Abstract: The present embodiments relate to establishing secure data communication using an Elliptic-curve Diffie-Hellman ephemeral (ECDHE) key agreement procedure. Devices in a network environment can utilize a key agreement procedure to establish secure communication between multiple application layers in a micro service architecture. Particularly, a tunnel can be established between a mobile device and an encryption service by transmitting key information between the mobile device and the encryption service. This can allow for encryption keys to only be accurately generated by the mobile device and encryption service. Accordingly, intermediary nodes may be unable to decrypt the data, allowing for safe and secure transport of sensitive data.

Abstract: Conventionally, a neuronal controller located inside the central nervous system governing the maintenance of the upright posture of the human body is designed from a control system perspective using proportional-integral-derivative (PID) controllers, wherein human postural sway is modeled either along a sagittal plan or along a frontal plane separately resulting in limited insights on intricacies of a governing neuronal controller. Also, existing neuronal controllers using a reinforcement learning (RL) paradigm are based on complex actor-critic on-policy algorithms. Analyzing human postural sway is critical to detect markers for progression of balance impairments. The present disclosure facilitates modelling the neuronal controller using a simplified RL algorithm, capable of producing postural sway characteristics in both sagittal and frontal plane together.
