Abstract: A rotor for a fluid machine includes a wheel that is supported for rotation about an axis of rotation. The wheel includes a back wall with an outer rim edge. The rotor also includes a plurality of blades that are attached to the back wall and that are spaced apart about the axis of rotation. Moreover, the rotor includes an inter-blade area on the back wall between neighboring ones of the plurality of blades. Furthermore, the rotor includes a balancing feature that is included in the inter-blade area on the back wall. The balancing feature intersects and defines part of the outer rim edge.

Abstract: Example techniques of this disclosure are directed determining one or more values that represent a monitoring attribute for one or more body-worn tracking devices (BWTDs). In some instances, the techniques include determining a compliance metric that represents a level of compliance for at least one offender. That is, the compliance metric may be a quantitative value that represents whether a user wearing BWTD is complying with established rules or desired behaviors.

Abstract: In some examples, an article includes a substrate having a surface; a parent optical element set comprising one or more parent optical elements disposed on the surface of the substrate, a child optical element set comprising one or more child optical elements disposed on the surface of the substrate. Each of the parent optical elements has a first retroreflective property and each of the child optical elements has a second retroreflective property different from the first retroreflective property.

Abstract: A system and method for assessing the co-scholastic skills of users have been disclosed. The system envisaged by the present disclosure envisages screening speechless short films to individuals in order to assess their strengths and weaknesses in co scholastic areas such as attitude towards life, moral values, critical thinking skills, creative thinking skills, decision making skills, analytical skills; problem solving skills, communication skills and emotional sensitivity. The system exploits various ideas, concepts and messages imparted by the short speechless movies to enhance the co-scholastic skills of individuals. The user is required to view the short speechless film displayed on a user interface. Subsequent to viewing the short speechless film, the user is required to answer an assessment test, preferably online assessment test. Based on the answers of users to the displayed assessment questions, the user's competency in co-scholastic skills is determined by an assessment processor.

Abstract: Embodiments of the present invention provide a method, system and computer program product for dual timer fragment caching. In an embodiment of the invention, a dual timer fragment caching method can include establishing both a soft timeout and also a hard timeout for each fragment in a fragment cache. The method further can include managing the fragment cache by evicting fragments in the fragment cache subsequent to a lapsing of a corresponding hard timeout. The management of the fragment cache also can include responding to multiple requests by multiple requestors for a stale fragment in the fragment cache with a lapsed corresponding soft timeout by returning the stale fragment from the fragment cache to some of the requestors, by retrieving and returning a new form of the stale fragment to others of the requestors, and by replacing the stale fragment in the fragment cache with the new form of the stale fragment with a reset soft timeout and hard timeout.

Abstract: Under the present invention, there is provided a voting mechanism for assigning an application server of an application server cluster the task of invalidating all sessions containing listeners in the cluster for a web application. A method for session invalidation processing comprises assigning a vote to a web application upon launch of the web application in an application server of the application server cluster, broadcasting the vote to other application servers of the application server cluster, receiving a vote for the web application from each of the other application servers in the application server cluster in which the web application has been launched, and assigning invalidation processing to the application server containing the web application having the highest vote. The votes are dynamically updated upon the removal or addition of an application server from/to the application server cluster.
