    摘要： Methods, computer programs, and systems for managing thread performance in a computing environment based on cache occupancy are provided. In one embodiment, a computer implemented method assigns a thread performance counter to threads being created to measure the number of cache misses for the threads. The thread performance counter is deduced in one embodiment based on performance counters associated with each core in a processor. The method further calculates a self-thread value as the change in the thread performance counter of a given thread during a predetermined period, and an other-thread value as the sum of all the changes in the thread performance counters for all threads except for the given thread. Further, the method estimates a cache occupancy for the given thread based on a previous occupancy for the given thread, and the calculated shelf-thread and other-thread values. The estimated cache occupancy is used to assign computing environment resources to the given thread. In another embodiment, cache miss-rate curves are constructed for a thread to help analyze performance tradeoffs when changing cache allocations of the threads in the system.

    摘要： Knot rejects from chemical pulping processes are subjected to acid hydrolysis or an enzymatic hydrolysis treatment. The resultant hydrolysate is enriched with glucose, representing a value-added raw material for products using hexoses. The residue, separated from the said hydrolysate after the acid hydrolysis or enzyme treatment, consists of mainly knots or chips. The residue has a much improved aesthetic appearance which can be readily used as value-added raw materials for mulch or similar applications. The residue could also be extracted to obtain high value antioxidants and other nutraceutical chemicals such as lignans or can be utilized according to currently known practices including recooking, burning and depositing.

    摘要： This invention disclosed is a comprehensive power quality controller for substation in the electric power system and includes a Thyristor Controlled Reactor (TCR), pure tuned passive filter Zf, additional inductor L active power filter (APF), and a coupling transformer. The Thyristor Controlled Reactor (TCR) provides inductive reactive power and controls the active power filter (APF) as the current source, it is connected with the additional inductor La in parallel via the coupling transformer, then connected to the passive filter Zf in serial to consist a hybrid power filter system, which is connected to the power grid via the circuit breaker or thyristor. The comprehensive filter system provides required capacitive reactive power and filters the harmonic produced by the load and TCR system itself. Because the capacity of the active power filter (APF) is very small which is less than 1% of the harmonic source capacity, so it is a solution with low cost but simple and reliable control mode. It can suppress influence on the passive filter by the “background harmonic” of the substation and prevent the resonance occurred between the passive filter and power grid impedance.

    摘要翻译： 本发明公开了一种用于电力系统中变电站的综合功率质量控制器，包括晶闸管控制电抗器（TCR），纯调谐无源滤波器Z附加电感器L有功功率滤波器（APF） 和耦合变压器。 晶闸管控制反应器（TCR）提供感应无功功率并控制有源电力滤波器（APF）作为电流源，它通过耦合变压器并联连接到附加电感器L＆amp; 以串联方式连接到无源滤波器Z N以构成混合电力滤波器系统，该系统通过断路器或晶闸管连接到电网。 综合滤波系统提供所需的电容无功功率，并对由负载和TCR系统本身产生的谐波进行滤波。 由于有源电力滤波器（APF）的容量非常小，小于谐波源容量的1％，因此是一种低成本但简单可靠的控制方式的解决方案。 可以通过变电站的“背景谐波”来抑制无源滤波器的影响，防止无源滤波器与电网阻抗之间发生谐振。
