    摘要: A centrifugal compressor includes an asymmetric self-recirculating casing treatment that includes, on an inner face of a casing 10, a suction ring groove 1, a ring guide channel 2 and a back-flow ring groove 3 to form a self-recirculating channel. An axial-direction position Sr from an upstream end face of the suction ring groove to an impeller full blade leading edge 4 or a width br of the suction ring groove 1 is represented as A(α·D−β·D)2+A0 and is distributed in a parabolic shape in a circumferential direction. An initial phase angle θ0 is in a range of 0≦θ0≦2π. A circumferential angle α of the casing has a definition range of θ0≦α≦θ0+2λ. In the expression, A denotes a parameter of the parabola in the axial-direction position Sr or the width br, and A0 denotes an extreme of the axial-direction position Sr or the width br when corresponding circumferential angle β and the α are equal at an extreme point of distribution of the parabola.

    摘要: A method and system for distributing and enforcing security policies is provided. A firewall agent executing at a host computer system that is to be protected receives security policies for the enforcement engines responsible for enforcing the security policies on the host computer system. A security policy has rules that each provide a condition and action to be performed when the condition is satisfied. A rule also has a rule type that is used by the distribution system to identify the security components that are responsible for enforcing the rules. To distribute the security policies that have been received at a host computer system, the firewall agent identifies to which enforcement engine a rule applies based in part on rule type. The firewall agent then distributes the rule to the identified enforcement engine, which then enforces the rule.

    摘要: The present invention relates a method of supplying fuel to a fuel cell, which comprises steps of: feeding a specific amount of a fuel into a fuel cell; obtaining a second characteristic value at a specific time point; detecting and measuring a character of the fuel cell at a time interval before the specific time point for obtaining a second characteristic value; comparing the second characteristic value to the first characteristic value for enabling the fuel to be fed into the fuel cell while the second characteristic value is smaller that the first characteristic value. By the aforesaid method, the supplying of fuel to the fuel cell can be effectively controlled for optimizing the performance of the fuel cell without the use of fuel sensor required thereby and thus reducing the cost and complexity of manufacturing the fuel cell system.

    摘要: An apparatus for image rotation. The apparatus includes a first memory, a frame buffer, a rendering module, a rotation object determination module, a rotation module, and a replacing module. The rendering module renders a second image according to second image data. The rotation object determination module detects a variation between the first image and the second image to identify a first image variation object of the first image, a second image variation object of the second image, and a rotated first image variation object of the first rotation image. The rotation module rotates the second image variation object as a second image rotation object. The replacing module retains the first rotation image except the rotated first image variation object and replaces the rotated first image object of the first rotation image with the second image rotation object to form a rotated second image.
