Also, by adopting the parasitic n-p-n transistor as a surge protection element, it is possible to reduce the operating resistance in comparison with when using a parasitic n-p-n transistor as a surge protection element, and thus possible to improve the surge protection function. Further, by providing one surge protection element on the guard ring, rather than providing a surge protection element in each cell, it is possible minimize the effect of manufacturing variation (i.e., in-plane variation) on the surge protection function.

A variable compensation pass bias based on a state being sensed in non-volatile memory based is provided. Shifts in the apparent charge stored by a memory cell can occur because of coupling based on charge stored by adjacent cells.

Using two cameras located at different orthographic views of the line-of-fire (LOF) allows the pitching and yawing motion history of the projectile to be calculated in three dimensions (3D). In addition, input of the camera locations, cannon trunnion location, and the cannon pointing direction allows for automatic correction for camera misalignment.

A global, cross-wafer model characterizes a structural parameter as a function of location on the wafer. A measurement model is optimized by constraining the measurement model with the cross-wafer model of process variations. In some examples, the cross-wafer model is itself a parameterized model. However, the cross-wafer model characterizes the values of a structural parameter at any location on the wafer with far fewer parameters than a measurement model that treats the structural parameter as unknown at every location. In some examples, the cross-wafer model gives rise to constraints among unknown structural parameter values based on location on the wafer. In one example, the cross-wafer model relates the values of structural parameters associated with groups of measurement sites based on their location on the wafer.

The trend of analyzing big data in artificial intelligence requires more scalable machine learning algorithms, among which clustering is a fundamental and arguably the most widely applied method. To extend the applications of regular vector-based clustering algorithms, the Discrete Distribution (D2) clustering algorithm has been developed for clustering bags of weighted vectors which are well adopted in many emerging machine learning applications. The high computational complexity of D2-clustering limits its impact in solving massive learning problems. Here we present a parallel D2-clustering algorithm with substantially improved scalability. We develop a hierarchical structure for parallel computing in order to achieve a balance between the individual-node computation and the integration process of the algorithm. The parallel algorithm achieves significant speed-up with minor accuracy loss.

Electronic garbage collection moves objects within memory to consolidate the objects thereby reducing access time and improving memory performance. Transactions occurring in an atomic transactional memory appear to occur instantaneously—such that the transaction completes in its entirety or is aborted. A garbage collection circuit attempts to move a memory object from a first memory location to a second memory location using a transactional fast-path move operation. If the transactional fast-path move operation is unsuccessful after a number of attempts, the garbage collection circuit attempts to move the object using a non-transactional slow-path move.

Technology described herein includes an arrangement whereby a hardware-based solution is implemented to enable mirroring of NVRAM data in a master server directly to NVRAM in a sleeper server. Both the master server and sleeper server implement a like motherboard unit, which is configured to implement the mirroring technology. That is, the roles of master and sleeper may be reversed. The master server includes a hardware module that monitors (but does not affect) NVRAM operations at the master server, and replicates those operations via a high speed communications link, such as a fiber optic link, to the sleeper server. The term “high speed communications link” refers to a link with at least 2.5 gigabit speed, and preferably at least 5 gigabit speed. The sleeper server is configured to, when in sleeper mode, suspend control of its own NVRAM module. Instead, the NVRAM module is controlled by a module that is configured to receive NVRAM operations via the fiber optic link, and apply those operations. In this manner, there is a direct mirroring of all master NVRAM content affected in the master's NVRAM to the sleeper's NVRAM. Using technology described herein, this is affected at an “atomic” (e.g. NVRAM bus cycle) level.

One or more techniques and/or systems are provided for multicast transport configuration, for multicast transport, and/or for fault policy implementation. In an example, a multicast component may receive a data copy request from an application to copy data to multiple destinations. A scheduler component may create a transport schedule specifying an order with which to facilitate data copy operations across transports, such as heterogeneous transports, to the destinations. A dispatcher component may apply application specified transport modifiers to the data copy operations (e.g., a modification to a quality of service for a transport). The dispatcher component may facilitate the data copy operations and provide operation result information to a policy agent. The policy agent may provide notifications of data copy operation statuses from the operation result information and/or may implement a fault policy (e.g., a retry on a different transport) for a data copy operation that experienced a fault.

A recording device 11 has a control unit 20 that executes multiple restore processes. The control unit restores a backbone system based on a restore file stored in a USB memory UM if the recording device 11 is started with the USB memory UM already connected. The control unit initializes the backbone system based on an initialization file in the USB memory UM when the USB memory UM is newly connected while the recording device 11 is already running. The control unit creates a restore file to restore the backbone system, and saves the created restore file to the USB memory UM if an initialization file is not already stored in the USB memory UM.

An information processing apparatus protects data stored in a storage device by saving setting data stored on a first storage device to a second storage device when the first storage device fails, or when an encryption function is enabled or disabled. The process of protecting the date includes, after a reservation for saving setting data is made, saving the setting data, cancelling the reservation, and making a reservation for restoring the setting data. If the setting data is to be restored, it is determined whether the reservation for restoring the setting data has been made, and if the reservation has been made, the setting data is restored to the first storage device.
