Abstract: A security policy process which provides role-based permissions for hierarchically organized system resources such as domains, clusters, application servers, and resources, as well as topic structures for messaging services. Groups of permissions are assigned to roles, and each user is assigned a role and a level of access within the hierarchy of system resources or topics. Forward or reverse inheritance is applied to each user level-role assignment such that each user is allowed all permissions for ancestors to the assigned level or descendants to the assigned level. This allows simplified security policy definition and maintenance of user permissions as each user's permission list must only be configured and managed at one hierarchical level with one role.

Abstract: Testing J2EE applications, wherein J2EE applications comprise modules, the testing including identifying (204), from an application deployment descriptor, modules comprised within the J2EE application; identifying, from an identified module, at least one QOS element; and identifying, from the identified QOS element, a software resource to be tested. Typical embodiments further including generating Java test code; identifying, for the software resource to be tested, a user identification and a user password for a user that is a member of a role intended to protect the software resource; and testing the software resource to be tested by use of the Java test code, including passing as parameters to the Java test code at run time the user identification and user password.

Abstract: A system and method are used to evaluate concavities in a complex surface, such as for determining protein pockets in a protein model.

Abstract: A method and apparatus for optimizing references to objects in a distributed data processing system. A method is invoked in a client process by client application on a target object. In response to determining that the target object is on a remote process reference, a smart proxy determines whether the message can be processed within the client process. In response to determining that the message can be processed in the client process, the message is processed locally. Otherwise the message is sent to the target object for processing.

Abstract: A fluted tube, defined by a multiplicity of parallel flutes extending over the length of the tube, is constructed by providing a flat portion of sheet metal, forming a series of undulations in one portion to form a corrugated section which is allowed to adjoin and be continuous with a flat section at a transition line or point. The sheet is engaged with tynes at the transition point and simultaneously welded as it is rolled into a spiral to form a multiplicity of flutes each bound by an undulation and a portion of the flat sheet metal. The flat sheet section can have a sufficient length so that it defines the last exterior layer of the spirally wound fluted structure to form a smooth walled, tubular envelope.

Abstract: Apparatus used, inter alia, for the production of printed labels employing self-adhesive stock mounted on a backing sheet. The labels are chosen as regards content or layout and as regards width by the user, the apparatus being capable of producing labels of any kind. The blank stock is fed through a printing device and thereafter through a rotary die-cutter. The printed and die-cut stock is then fed to a location at which the backing sheet supporting the printed labels are separated from the waste paper. At said location, an abrupt change of direction in the path of travel is imparted to the backing sheet.
