20090194616Sporoderm-Broken Polypore Production - A cryogenic grinding mill for grinding organic base material pieces into sub-micron-sized powder particles. An upper grinding block is rotated relative to a stationary lower grinding block by a motor, and is maintained at a temperature below −150° C. by a cryogenic system including an annular liquid nitrogen chamber disposed around the grinding blocks. The upper grinding block defines a trench for receiving base material pieces fed by a feed system, and includes through-holes that extend from the trench to a grinding region formed between the grinding surfaces of the upper and lower blocks. When the upper grinding block is rotated, the base material pieces are gravity-fed from the trench to the grinding region, and ground powder material is forced to a peripheral edge of the grinding region. The powder material is then filtered, and particles having an undesirably large size are fed back into the trench for re-grinding.08-06-2009

20110173038CONSTRAINT-CONSCIOUS OPTIMAL SCHEDULING FOR CLOUD INFRASTRUCTURES - Systems and methods are disclosed to schedule jobs in a cloud computing infrastructure by receiving in a first queue jobs with deadlines or constraints specified in a hard service level agreement (SLA); receiving in a second queue jobs with a penalty cost metric specified in a soft SLA; and minimizing both constraint violation count and total penalty cost in the cloud computing infrastructure by identifying jobs with deadlines in the first queue and delaying jobs in the first queue within a predetermined slack range in favor of jobs in the second queue to improve the penalty cost metric.07-14-2011
20110173626EFFICIENT MAINTENANCE OF JOB PRIORITIZATION FOR PROFIT MAXIMIZATION IN CLOUD SERVICE DELIVERY INFRASTRUCTURES - Systems and methods are disclosed for efficient maintenance of job prioritization for profit maximization in cloud-based service delivery infrastructures with multi-step cost structure support by breaking multiple steps in the SLA of a job into corresponding cost steps; generating a segmented cost function for each cost step; creating a cost-based-scheduling (CBS)-priority value associated with a validity period for each segment based on the segmented cost function; and choosing the job with the highest CBS priority value.07-14-2011
20110219031SYSTEMS AND METHODS FOR SLA-AWARE SCHEDULING IN CLOUD COMPUTING - Systems and methods are disclosed for scheduling one or more queries for execution with one or more cloud computers by applying a service level agreement (SLA) analysis using an SLA-tree data structure to each query in a query queue; using the SLA-tree data structure to determine an overall profit in the query queue; and generating a profit-oriented schedule to select the next query for execution by the cloud computers.09-08-2011

20090187914SYSTEM AND METHOD FOR LOAD SHEDDING IN DATA MINING AND KNOWLEDGE DISCOVERY FROM STREAM DATA - Load shedding schemes for mining data streams. A scoring function is used to rank the importance of stream elements, and those elements with high importance are investigated. In the context of not knowing the exact feature values of a data stream, the use of a Markov model is proposed herein for predicting the feature distribution of a data stream. Based on the predicted feature distribution, one can make classification decisions to maximize the expected benefits. In addition, there is proposed herein the employment of a quality of decision (QoD) metric to measure the level of uncertainty in decisions and to guide load shedding. A load shedding scheme such as presented herein assigns available resources to multiple data streams to maximize the quality of classification decisions. Furthermore, such a load shedding scheme is able to learn and adapt to changing data characteristics in the data streams.07-23-2009

20120022910INTELLIGENT MANAGEMENT OF VIRTUALIZED RESOURCES FOR CLOUD DATABASE SYSTEMS - Systems and methods are disclosed to manage resources in a cloud-based computing system by generating a model of a relationship between cloud database resources and an expected profit based on cloud-server system parameters and service level agreements (SLAs) that indicates profits for different system performances, wherein the model comprises a two level optimization/control problem, wherein model receives system metrics, number of replicas, and arrival rate as the multiple input; and dynamically adjusting resource allocation among different customers based on current customer workload and the expected profit to maximize the expected profit for a cloud computing service provider.01-26-2012
20120023501HIGHLY SCALABLE SLA-AWARE SCHEDULING FOR CLOUD SERVICES - An efficient cost-based scheduling method called incremental cost-based scheduling, iCBS, maps each job, based on its arrival time and SLA function, to a fixed point in the dual space of linear functions. Due to this mapping, in the dual space, the job will not change their locations over time. Instead, at the time of selecting the next job with the highest priority to execute, a line with appropriate angle in the query space is used to locate the current job with the highest CBS score in logarithmic time. Because only those points that are located on the convex hull in the dual space can be chosen, a dynamic convex hull maintaining method incrementally maintains the job with the highest CBS score over time.01-26-2012

20100171478CLOSED-LOOP DIGITAL CONTROL SYSTEM FOR A DC/DC CONVERTER - A control system comprises a DC/DC converter that includes first and second inductances, that receives a first DC voltage and that generates a second DC voltage. A control module selectively charges or discharges the first inductance while discharging or charging the second inductance during a first mode and one of charges both of the first and second inductances or discharges both of the first and second inductances during a second mode.07-08-2010
