Abstract: A computing system retrieves ball-by-ball data for a plurality of sporting events. The computing system generates a trained neural network based on ball-by-ball data supplemented with ball-by-ball data with ball-by-ball match context features and personalized embeddings based on a batsman and a bowler for each delivery. The computing system receives a target batsman and a target bowler for a pitch to be delivered in a target event. The computing system identifies target ball-by-ball data for a window of pitches preceding the to be delivered pitch. The computing system retrieves historical ball-by-ball data for each of the target batsman and the target bowler. The computing system generates personalized embeddings for both the target batsman and the target bowler based on the historical ball-by-ball data. The computing system predicts a shot type for the pitch to be delivered based on the target ball-by-ball data and the personalized embeddings.

Abstract: A computing system and method for determining part utilization by machines, such as aeronautical vehicles, are disclosed. According to an example, a first data set is obtained that identifies a physical parameter defining a configuration of a first population of aeronautical vehicles and a part applicability of an identified part for the first population. A second data set is obtained that identifies a physical parameter defining a configuration of a second population of aeronautical vehicles that differs from the physical parameter of the first population. An inferred part applicability is determined for the second population that describes a probability that the identified part is utilized by the second population. A part utilization value is output that identifies a measurement of part utilization of the identified part for the second population that is based on the inferred part applicability.

Abstract: A segmentation firewall executing on a host enforces a segmentation policy. In a co-existence mode, the segmentation firewall operates in co-existence with a system firewall that enforces a security policy. The segmentation firewall is configured to either drop packets that do not match any permissive rule or pass packets that match a permissive rule to the system firewall to enable the system firewall to determine whether to drop or accept the passed packets. To enable efficient operation of the segmentation firewall when operating in co-existence with the system firewall, the segmentation firewall may include a plurality of rule chains and may be configured to exit a chain and bypass remaining rule chains upon an input packet matching a permissive rule of the segmentation policy.

Abstract: Systems, methods, and software can be used to improve security of an authentication process in a cargo shipping system. In some aspect, an authentication request message is received at a sensor from a cargo tracking device. The authentication request message includes a key that the sensor will use to decrypt its encrypted public key/private key pair. In response to the authentication request message, the sensor sends an authentication response message to the cargo tracking device that is encrypted using a derived symmetric key. The cargo tracking device sends an authentication confirmation message to the sensor in response to the authentication response message.

Abstract: A fluid ejector for ejecting discrete volumes of ejectant includes a body with opposing first and second surfaces. One or more nozzles are defined as conduits extending through the body between the surfaces to connect first and second orifices at the first and second surfaces respectively. The fluid ejector further includes a gas supply means having a gas outlet and an ejectant supply means. The ejectant supply means supplies the ejectant to the nozzles at a pressure above ambient via their supply orifices. The supply orifice is defined in a conduit's side or is the second orifice. Relative movement of the gas supply means and body exposes first orifices to the gas outlet allowing the gas supply means to supply gas at a pressure above ambient, wherein a pressure difference thereby created between the first and second orifices causes ejection of the ejectant from the nozzles through the second orifices.

Abstract: An elliptic curve random number generator avoids escrow keys by choosing a point Q on the elliptic curve as verifiably random. An arbitrary string is chosen and a hash of that string computed. The hash is then converted to a field element of the desired field, the field element regarded as the x-coordinate of a point Q on the elliptic curve and the x-coordinate is tested for validity on the desired elliptic curve. If valid, the x-coordinate is decompressed to the point Q, wherein the choice of which is the two points is also derived from the hash value. Intentional use of escrow keys can provide for back up functionality. The relationship between P and Q is used as an escrow key and stored by for a security domain. The administrator logs the output of the generator to reconstruct the random number with the escrow key.
