Abstract: A method and apparatus for controlling a virtual camera in a game are disclosed. In the present application, a virtual camera is controlled to shift in response to a first touch operation for a visual field control region, and the virtual camera is controlled to enter a locked state according to a locking operation, thereby locking a game scene captured by the shifted virtual camera as a game scene rendered on a graphical user interface until restoring to control the movement of the virtual camera according to the position change of a virtual character when the locked state is unlocked.

Abstract: A method and apparatus for controlling a virtual camera in a game are disclosed. In the present disclosure, it is detected whether a movement of a virtual character toward a first direction satisfies a preset condition, when the preset condition is satisfied, a shifting direction of the virtual camera is determined, and the virtual camera is controlled to shift toward the shifting direction while moving according to a change of position of the virtual character, thereby a game scene image captured by the shifted virtual camera is displayed on a Graphical User Interface (GUI).

Abstract: A method and an apparatus for verifying an identity document, an electronic device, and a storage medium include: collecting an identity document image of a current identity document by means of a first camera; recognizing characters in the identity document image to obtain first identity document data; obtaining second identity document data of the identity document by means of an identity document reader; and verifying authenticity of the identity document according to the first identity document data and the second identity document data.

Abstract: A printing system and method for forming an ink droplet through the use of a multi-pulse driving signal to increase the printing frequency without reducing the droplet size by applying a multi-pulse driving signal to a small nozzle and to increase the inkjet printing speed by using a smaller nozzle to produce the same-size droplet using a multi-pulse driving signal, which allow for higher printing frequency due to the smaller nozzle size as dictated by the fundamental droplet formation dynamics.

Abstract: A mechanism called time-deterministic replay (TOR) that can reproduce the execution of a program, including its precise timing. Without TOR, reproducing the timing of an execution is difficult because there are many sources of timing variability. TOR uses a combination of techniques to either mitigate or eliminate most of these sources of variability. Using a prototype implementation of TOR in a Java Virtual Machine, we show it is possible to reproduce the timing to within 1.85% of the original execution. A study of one of the applications of TOR is described: the detection of a covert timing channel. Timing channels can be used to exfiltrate information from a compromised machine by subtly varying timing of the machine's outputs, TOR can detect this variation. Unlike prior solutions, which generally look for a specific type of timing channel, our approach can detect a wide variety of channels with high accuracy.

Abstract: A 3-D printing system comprising a plurality of printers. The printers are motorized to allow movement in X and Y directions or to rotate freely. Each printer may have one or more printheads. Also provided is a surface independent from said printers adapted to receive a printed object.

Abstract: The description relates to cloud-edge topologies. Some aspects relate to cloud-edge applications and resource usage in various cloud-edge topologies. Another aspect of the present cloud-edge topologies can relate to the specification of cloud-edge applications using a temporal language. A further aspect can involve an architecture that runs data stream management systems (DSMSs) engines on the cloud and cloud-edge computers to run query parts.

Abstract: A negative electrode for a rechargeable battery comprises a zinc oxide member doped with one or more metals and thereafter coated with a conductive layer of carbon or carbon doped with an element selected from the group consisting of fluorine, nitrogen, boron, and a mixture of two or more thereof. The electrode material is prepared by admixing ZnO or doped ZnO with carbon or a carbon-based material and then heating the admixture to form ZnO with a conductive layer. The ZnO can be doped with a first metal and then a second metal.
