摘要： The disclosure provides a method for loading uplink simulation data of a terminal, and a terminal, which belong to the field of wireless communication. The method comprises: after being powered on, the terminal imports simulation data to a memory of an uplink master-control Digital Signal Processor (DSP) of the terminal; the terminal performs uplink access, and transmits the simulation data to a channelized memory after the uplink access succeeds; then the terminal performs Inverse Fast Fourier Transform (IFFT) on the simulation data in each uplink sub-frame, and transmits the transformed simulation data to a base station via a radio frequency unit. According to the disclosure, the problem that a single terminal can not load data services of multiple terminals at the same time is solved; therefore, the effect of simulating to load noise transmission, load multi-terminal transmission, and load noise and terminal service transmission is achieved.

摘要： Video data is processed with region-based warping. In accordance with various example embodiments, video data having a plurality of source video frames is processed as follows, for each source video frame. Pixels representing the source video frame and at least one temporally-adjacent video frame are used to generate a motion history map, based upon frame-to-frame movement of at least one region in the source video frame and temporally-adjacent video frames. At least one salient region is identified in the source video frame based upon the motion history map and static image saliency data. Weighting data is determined for warping pixels corresponding to background regions of the source video frame differently than pixels corresponding to the at least one salient region in the source video frame. Using the weighting data, the pixels representing the source video frame are warped to generate pixels representing a warped video frame.

摘要： A method, system and computer program product is disclosed for supporting role-based access control in a collaborative environment, wherein pluralities of users work together in a collaborative process using a software system. The method comprises componentizing the software system into a multitude of software components, and limiting access to specific software components to certain users based on roles assigned to the users as defined by a run-time state of the collaborative process. The set of components that a user can access is dynamic, that set can change based on the “context” or the step where the user is in a collaborative workflow/process. Thus, in comparison with traditional access control mechanisms, an embodiment of the invention combines three different elements: a) the set of components that comprise the application is partitioned in such a way as to make componentized role-based access control feasible, b) a method for specifying inter-component dependencies to enable role-based groups, and c) enabling the modification of the access privileges based on contextual information from a collaborative process.

摘要翻译： 公开了用于在协作环境中支持基于角色的访问控制的方法，系统和计算机程序产品，其中多个用户使用软件系统在协作过程中一起工作。 该方法包括将软件系统组合成多个软件组件，并且基于由协作过程的运行时状态定义的分配给用户的角色来限制对某些用户的特定软件组件的访问。 用户可以访问的组件集合是动态的，该集合可以基于“上下文”或用户处于协作工作流/进程中的步骤而改变。 因此，与传统的访问控制机制相比，本发明的实施例组合了三个不同的元素：a）构成应用的组件集合被划分成使组件化的基于角色的访问控制可行，b） 用于指定组件间依赖性以启用基于角色的组，以及c）基于协作过程的上下文信息来启用对访问权限的修改。
