Abstract: The performance of a device can be improved by intelligently terminating (or otherwise operationally adjusting) applications, services, or processes that the user is unlikely to access on the device. Information such as system event data and hint data can be obtained from various sources and fed to one or more predictor algorithms, which can determine the likelihood that a user will access various applications over a period of time. Other determinations can be made as well, such as which applications are most likely causing degradation in performance. Various termination actions can be selected to be performed, which can in some cases adjust the applications selected for termination by an operating system of the device. Once a set of actions is selected, those termination actions can be performed for the associated application(s) at least to the extent needed to restore health of the device.

Abstract: A system and method for detecting pressure deviation of a first fluid in an engine is disclosed. The method may comprise calculating, for each of a plurality of measurements, a delta between an actual first fluid pressure and a target pressure, summing each delta obtained from the calculating, and determining pressure deviation of the first fluid based on a cumulative sum of the deltas. In an embodiment, the first fluid may be natural gas.

Abstract: Improved methods of oxidative dehydrogenation (ODH) of short chain alkanes or ethylbenzene to the corresponding olefins, and improved methods of oxidative coupling of methane (OCM) to ethylene and/or ethane, are disclosed. The disclosed methods use boron- or nitride-containing catalysts, and result in improved selectivity and/or byproduct profiles than methods using conventional ODH or OCM catalysts.

Abstract: A compression ignition engine is fueled from common rail fuel injectors that predominately inject natural gas fuel that is compression ignited with a small pilot injection of liquid diesel fuel. Before and after a rapid load loss transient, the liquid and gaseous rail pressures are controlled toward respective pressures based upon engine speed and load. During the transient, the liquid rail pressure is controlled relative to the gas rail pressure in order to maintain the liquid rail pressure greater than the gas pressure during the transient to avoid migration gaseous fuel into the liquid fuel side of the system.

Abstract: Disclosed is a method of modifying a graphics command. The method receives a graphics command comprising a drawing operation and a pattern (ROP3) of the region and obtains spatial frequencies of the pattern. The method determines if the obtained spatial frequencies of the pattern in the graphics command define a transparency attribute of the region to be rendered and replaces at least the pattern in the graphics command with a transparency coefficient based on the obtained spatial frequencies.

Abstract: A compression ignition engine is fueled from common rail fuel injectors that predominately inject natural gas fuel that is compression ignited with a small pilot injection of liquid diesel fuel. Before and after a rapid fueling increase transient, the liquid and gaseous rail pressures are controlled toward respective pressures based upon engine speed and load. During the transient, the liquid rail pressure is controlled toward an elevated liquid pressure in order to cause a surge in the supply of gaseous fuel to the gaseous fuel common rail to proactively satisfy the increased gaseous fuel injection rate while obviating a substantial pressure deficit in the gaseous fuel common rail.

Abstract: The solar tracker comprises a base (1) and a solar panel (2) having first and second opposite ends (2a, 2b). The first end (2a) can be connected to the base (1) by a first shaft (E1) and the second end (2b) can be connected to the base (1) by a second shaft (E2), such that said solar panel (2) can pivot with respect to the base (1) alternately around the first shaft (E1) and around the second shaft (E2) under the drive of a lifting mechanism. An automatic connection/disconnection device connects the second end (2b) of the solar panel (2) to the base (1) while at the same time disconnecting the first end (2a) of the solar panel (2) from the base (1), and vice versa, every time the solar panel (2) reaches a position parallel to the base (1) for inverting the inclination of the solar panel (2) with respect to the base (1).

Abstract: Some examples include testing of software able to render a content item on a display of an electronic device. The testing may include capturing images of rendered portions of a content item and comparing the captured images with previously obtained reference images that have been verified to be correctly rendered. The testing techniques can be applied to conversion software that converts digital content items from one format to another and/or testing of the converted content items themselves. Additionally, content presentation software that displays digital content items on an electronic device, such as by interacting with rendering software, may also be tested using a similar technique.

Abstract: A system, related method and computer program product are disclosed for controlling fuel mass of CNG received by an engine. The system may comprise a heat exchanger configured to receive CLNG and supply coolant and to output CNG and return coolant, an injector configured to inject CNG into the engine, a gas line between the injector and heat exchanger, a control valve configured to receive return coolant from the heat exchanger and to change the amount of return coolant flowing through control valve, and a controller connected to the control valve. The gas line may be configured to carry CNG from the heat exchanger to the injector. The controller may be configured to maintain a Gas Line Temperature within an operating range by adjusting the amount of return coolant flowing through the control valve based, at least in part, on the Gas Line Temperature and a Target Return Coolant Temperature.

Abstract: A dual fuel common rail system may be operated in a regular mode in which a relatively large charge of gaseous fuel is ignited by compression igniting a relatively small injection quantity of liquid diesel fuel. The dual fuel system may be operated in a single fuel limp home mode in which liquid diesel fuel is injected at higher pressures. When transitioning from the single fuel limp home mode to the dual fuel regular mode, accumulated leaked liquid fuel in the gaseous nozzle chamber of each fuel injector is purged and burned in the respective engine cylinder.
