Abstract: In a method for visualizing query results in stream processing systems, a visualization service receives a query from a client to visualize data in a stream processing application. The query is sent from the visualization service to a query-able operator of the stream processing application. At the query-able operator, an operation is performed using history data in the query-able operator to produce a first result that satisfies the query and the first result is sent to the visualization service. At the query-able operator, another operation is performed using new data received by the query-able operator to produce a second result that satisfies the query and the second result is sent to the visualization service. The first and second results are output from the visualization service to the client.

Abstract: Computer memory management systems and methods are provided in which data block buffering and priority scheduling protocols are utilized in compressed memory systems to mask the latency associated with memory reorganization work following access to compressed main memory. In particular, data block buffers and priority scheduling protocols are implemented to delay and prioritize memory reorganization work to allow resources to be used for serving new memory access requests and other high priority commands.

Abstract: A method for assembling stream processing graphs in a stream processing system, includes: performing, in an offline manner, translating a plurality of processing element and data source descriptions into a planning language and performing reasoning on the plurality of processing element and data source descriptions during the translation; and performing, in an online manner, receiving a processing request that specifies a desired processing outcome; translating the processing request into a planning goal; and assembling a plurality of stream processing graphs, each of the processing graphs including a plurality of the translated and reasoned processing elements or data sources that satisfy the desired processing outcome.

Abstract: An exemplary method is provided for managing and mitigating security risks through planning. A first security-related information of a requested product is received. A second security-related information of resources that are available for producing the requested product is received. A multi-stage process with security risks managed by the first security-related information and the second security-related information is performed to produce the requested product.

Abstract: A random bit generator and a method thereof are provided. The random bit generator includes an amplifier, a comparing circuit, an oscillator, a sampler, and a storage circuit. The amplifier amplifies a difference between input signals generated based on thermal noise. The comparing circuit compares an alternating current (AC) signal output from the amplifier with a direct current (DC) signal obtained by low-pass filtering the AC signal and outputs a signal according to the comparison result. The oscillator may be implemented with a resistor-capacitor (R-C) oscillator. The oscillator consumes lower current and occupies a smaller layout area than a voltage controlled oscillator (VCO) and outputs an oscillation signal. The sampler samples the oscillation signal output from the oscillator in response to the output signal of the comparing circuit. The storage circuit stores an output signal of the sampler in response to a clock signal.

Abstract: There is provided a method for automatically segmenting lung nodules in a three-dimensional (3D) Computed Tomography (CT) volume dataset. An input is received corresponding to a user-selected point near a boundary of a nodule. A model is constructed of the nodule from the user-selected point, the model being a deformable circle having a set of parameters ? that represent a shape of the nodule. Continuous parts of the boundary and discontinuities of the boundary are estimated until the set of parameters ? converges, using dynamic programming and Expectation Maximization (EM). The nodule is segmented, based on estimates of the continuous parts of the boundary and the discontinuities of the boundary.
