A centrifugal fan includes a main shroud and a sub shroud. The main shroud is configured to connect upper ends of outer rims of a plurality of blades spaced apart from one another in a circumferential direction of a base. The sub shroud is provided at the upper end of the outer rim of each blade and serves to prevent air from moving from a pressure surface to a negative pressure surface of each blade by passing over an upper end of the blade.

Methods and systems for identifying a trustable workflow based on a comprehensive trust model. One or more trustable links between two or more abstract services among a number of combinations of concrete services can be searched and the trustable link combined to realize an abstract workflow so as to construct a candidate trustable workflow space. The K trustable workflows can be determined by randomly selecting the trustable link with respect to each pair of connected abstract services and combining the selected trustable links. The trustable link in the workflow can be selected to be replaced with another candidate trustable link to provide a higher selection probability to the trustable link in a critical path.

A stent for securing a passageway of a body lumen in a constricted portion of the body lumen is disclosed. The stent includes a first cylindrical band body formed in a zigzag shape having a plurality of straight sections interconnected by first peaks and first valleys and having opposite ends that are integrally formed, a second cylindrical band body having a same structure as the first cylindrical band body, the second cylindrical band body being disposed such that second valleys of the second cylindrical band body face the respective first peaks of the first cylindrical band body and second peaks of the second cylindrical band body face the respective first valleys of the first cylindrical band body with a plurality of predetermined gaps of a first row, thereby defining a plurality of rhombus spaces of a first row, at least one first link member that is provided in at least one rhombus spaces of the first row to interconnect the first and second band bodies, at least one second link members that are provided in at least one rhombus spaces of the second row to interconnect the second and third band bodies.
摘要:
The present invention relates to a method and a system for controlling an operation of a damper clutch for reducing a shock that occurs when a damper clutch is directly coupled, and reducing a time to become completely coupled. A method for controlling an operation of a damper clutch according to an exemplary embodiment of the present invention includes determining whether a direct coupling condition of a damper clutch is satisfied, performing an engine torque reduction control for reducing an engine torque when the direct coupling condition is satisfied, performing a damper clutch coupling control such that the damper clutch is directly coupled after the engine torque is reduced, and returning the engine torque to a base state after direct coupling of the damper clutch is completed.
