Abstract: An information determining method and apparatus are provided. The method may include determining an aiming position of a virtual firearm being within an aiming assistance range of a target object. The method may further include determining, in response to a sequence of consecutive target firing operations for the virtual firearm, an aiming assistance strength of the virtual firearm based on the sequence. The method may further include providing, based on the aiming assistance strength, a first offset for drawing an aiming position of the virtual firearm to the target object; and controlling the virtual firearm to shoot based on the aiming position.

Abstract: A channel machining equipment and a channel machining method allow a wall of an internal curved channel in a workpiece to be conducted. A set of traction lines and guiding bodies are to support the EDM electrode and thus allow an electrode linked with the guide mechanism to substantially move in a central portion of the curved channel to optimize an EDM effect on the wall of the channel. Therefore, a precision machining process (such as grinding, EDM, and so on) can be conducted on the internal curved channel of the workpiece to make it have satisfactory wall roughness and shape precision according to predetermined standards, thereby solving the problem of failure in effectively machining the wall of the curved channel in the workpiece in the prior art.

Abstract: Aspects of the present disclosure describe rapid temperature measurement by wavelength modulation spectroscopy (WMS) that determines gas temperature from 2ƒ signals from two absorption lines by WMS methodologies even when the gas concentration is sufficiently high to saturate optical absorptions. In sharp contrast to the prior art, rapid temperature measurement by WMS according to aspects of the present disclosure employs both a 2ƒ signal ratio and gas concentration determined from the 2ƒ signal.

Abstract: Upon an installation of a new software release at a multitenant computing system, a list of layers of a pre-existing layer strategy in use at the multitenant computing system can be read. As part of the installation of the new release, an updated bottom layer in a repository of the multitenant computing system can also be installed. A target set of software components for a tenant of the multitenant computing system can be determined, for example by reading a metadata definition of the target set for a layer of a repository of the multitenant computing system to which the tenant is assigned. The tenant can be configured consistent with the target set of software components.
