A method for imaging an object in a computed tomography system with a plurality of sources comprising a first source and a second source, wherein the plurality of sources together with a detector array are mounted on a rotatable gantry, and wherein an intensity of the second source has unknown fluctuations is provided. The apparatus comprises a first member and a second member each having a handle portion on a first end and a jaw portion on an opposite end. The network node module is securely reconfigurable to any use mode in the set of use modes. Further, messages of the queue are persistent. 45 or less, and a maximum mole fraction of one compound as a single component in the ingredient and the ingredient is 0. Execution of the first computing job is scheduled to take place on a first computing node during the first time period, where a start time associated with the first time period is a time selected from the group consisting of a current time and a future time.
