Abstract: In an example method, a system obtains a data record indicating an anticipated change in an employment status of a user at an organization, including a data field indicating an effective time of the anticipated change. At a first time prior to the effective time, the system modifies an access privilege of the user with respect to computer resources of the organization, including (i) allowing the user to perform first operations using the computer resources between the first time and a second time subsequent to the first time, and (ii) preventing the user from performing second operations using the computer resources starting at the first time. At the second time, the system further modifies the access privilege of the user, including preventing the user from performing the operations using the computer resources starting at the second time.

Abstract: A method is provided for determining whether post-weld heat treatments should be required for external attachment welds in applications where stress corrosion cracking is a possibility. According to the method, residual stress values are measured in test samples welded at high input heat levels and test samples welded at low input heat levels for a variety of different wall thickness. A threshold residual stress level is determined according to a method of selecting a common pipe used in industry and measuring the residual stress level in the longitudinal seam of the pipe. The measured residual stress values for the high and low heat input welds are compared against the threshold to determine whether for a particular wall thickness, the high and low input data exceeds the threshold, indicating whether post-weld heat treatments are required.
