Abstract: A lamp including electrical leads extending into a supporting stem that are in communication with a base electrode for engagement to a light fixture; and a light engine comprising light emitting diode filaments that are in electrical communication with the electrical leads. The light emitting diode filaments including a circuit having a plurality of contact pads arranged along a length of a substrate. The light emitting diode filaments further include light emitting diode (LED) chips engaged to the contact pads along the length of the substrate to provide that the light emitting diode (LED) chips are electrically connected in series. In some embodiments, each light emitting diode (LED) chip includes at least a light transmission surface that is in contact with an individual portion of phosphor for the LED chip. In other embodiments, a phosphor layer extends over an island of LED chips.

Abstract: In example implementations, a method include receiving a request for a lock in a Mellor-Crummey Scott (MCS) lock protocol from a guest user that is context free (e.g., a process that does not bring a queue node). The lock determines that it contains a null value. The lock is granted to the guest user. A pi value is received from the guest user to store in the lock. The pi value notifies subsequent users that the guest user has the lock.

Abstract: A hardware-in-loop simulation experiment platform of multiple input and multiple output loop control for MSWI process includes a real equipment layer and a virtual object layer, where in the real equipment layer and the virtual object layer realize communication through hard wirings and data acquisition cards, the real equipment layer and virtual object layer realize communication in OPC mode through Ethernet; the real equipment layer comprises monitoring equipment and control equipment, and the virtual object layer comprises an MSWI actuator model, an MSWI instrument device model and an MSWI process object model which are respectively operated in different industrial personal computers. The hardware-in-loop simulation experiment platform of multiple input and multiple output loop control for MSWI process provided by the invention is used for providing a reliable engineering verification environment for MSWI process control.

Abstract: Hybrid concurrency control in a database transaction is disclosed. A contention value associated with a database object is read. The contention value is dynamically updated based on access patterns of the database object. If the contention value indicates the database object is under high contention, a pessimistic concurrency control mechanism is applied to the database object. An optimistic concurrency control mechanism is applied to the database object if the contention value does not indicate the database object is under high contention.

Abstract: A computer implemented method includes receiving multiple requests to update a data structure stored in non-volatile memory (NVM) and applying an atomic multiword update to the data structure to arbitrate access to the NVM. In a further embodiment, a computer implemented method includes allocating a descriptor for a persistent multi-word compare-and-swap operation (PMwCAS), specifying targeted addresses of words to be modified, returning an error if one of the targeted addresses contains a value not equal to a corresponding compare value, executing the operation atomically if the targeted addresses contain values that match the corresponding compare values, and aborting the operation responsive to the returned error.
