  • Publication number: 20180091414
    Abstract: An aspect of the present disclosure estimates effort required for testing web services deployed in an enterprise system. In one embodiment, a configuration data specifying complexity levels of web service operations and a number of test cases required for each of the complexity levels is maintained. Upon receiving data specifying a web service (deployed in the enterprise system) sought to be tested, a definition of the web service is inspected to identify web service operations provided by the web service. For each web service operation, a complexity level is determined, and a corresponding number of test cases required to be prepared for the determined complexity level is identified by examining the configuration data. A total number of test cases that is required to be prepared for testing the web service is then computed based on the identified number of test cases for the web service operations of the web service.

  • Publication number: 20180028960
    Abstract: Adsorbent materials are disclosed, along with filter elements containing the adsorbent materials methods of using adsorbents to remove slioxane contaminants from a gas stream. The method includes providing an adsorbent material that has been washed with an acid and passing a gas through the adsorbent material so as to reduce siloxane levels in the gas. A filter element for reducing siloxane levels in a gas includes a first adsorbent material, the first adsorbent material comprising an acid-washed adsorbent; and a second adsorbent material, the second adsorbent material comprising an acid-impregnated adsorbent.

  • Patent number: 9443040
    Abstract: A method of forming a hemming tool includes providing a computer generated model of a panel including a flange in an unhemmed position and of a hemming tool including a hemming surface. Hemming the flange with the hemming tool is virtually simulated in the computer generated model. At least one non-conformity is identified along the flange in the computer generated model after virtually simulating hemming. The computer generated model is then modified to a modified computer generated model by adjusting the flange to change the at least one defect. Hemming the flange in the unhemmed position with the hemming tool is then virtually simulated in the modified computer generated model in the modified computer generated model.
