Abstract: An operating system permits sharing of a sub-process (or process unit) across multiple processes (or tasks). Each shared sub-process has its own context. The sharing is enabled by tracking when a process invokes a sub-process. When a process invokes a sub-process, the process is designated as a parent process of the child sub-process. The invoked sub-process may require use of process level variable data. To enable storage of the process level variable data for each calling process, the variable data is stored in memory using a base address and a fixed offset. Although the based address may vary from process to process, the fixed offset remains the same across processes.

Abstract: A computing device receives a training data set that comprises a plurality of sensitive documents and a plurality of non-sensitive documents. The computing device determines a quality of the training data set. The quality may be determined using k-fold cross validation and/or latent semantic indexing. In response to determining that the training data set has a satisfactory quality, the computing device then analyzes the training data set using machine learning to train a machine learning-based detection (MLD) profile, the MLD profile to be used by a data loss prevention (DLP) system to classify new documents as sensitive documents or as non-sensitive documents.

Abstract: Systems and methods for obtaining an optimal pricing strategy in a service engagement are disclosed. A model is created for the service engagement between a client and vendor. For the service engagement, a pricing strategy is selected. The pricing strategy is selected from one of a fixed strategy, a variable strategy and a combination thereof. Subsequent to selecting the pricing strategy, a client payoff associated with the client and a vendor payoff associated with the vendor are computed. The model is simulated to obtain a time series data. Based on the simulation, an optimal pricing strategy is obtained by calculating an optimizer payoff function. The optimizer payoff function is calculated by assigning relative weights to the client payoff and the vendor payoff. The optimal pricing strategy is obtained by altering the pricing strategy to maximize the optimizer payoff function.

Abstract: A graphics rendering system is provided for controlling the rendering of images to manage expected errors. The graphics rendering system receives a specification of a render task to be performed to render an image of a graphics scene and then identifies computing devices that each have a graphics processing unit. The graphics rendering system directs each of the identified computing devices to render the image specified by the render task such that each identified computing device renders the same image. When the graphics rendering system detects that a computing device has completed the render task successfully, it provides the image rendered by that computing device as the rendered image of the render task such that any other image rendered by another of the computing devices is not needed.

Abstract: According to the invention, a PIR sensor system (100) comprises a first PIR sensor (1) associated with a first sensing region (11) and a second PIR sensor (2) associated with a second sensing region (12). The first and second sensing regions partially overlap and are divided into detection cells (46a-46f) and (45a-45d). Each detection cell is represented by predetermined characteristics of first and second output signals, which signals are based on input signals from first and second sensing elements (4-7) of each PIR sensor. Thereby different detection cells are encoded by a certain combination of signal characteristics (amplitude and sign) of the first and second output signals. Further, the PIR sensor system comprises a processing unit (15) configured to associate the characteristics of the first and second output signals with one of the detection cells for determining in which of the detection cells a heat source is positioned.

The model is optimized to obtain an optimal allocation of the plurality of configuration elements. The model is optimized by allocating another subset of the plurality of configuration elements to meet the SLA.
