Abstract: A system and method for tracking a user history, for presentation thereof within a browser display. An executable software construct operates at a client machine to trap object references, which are then transmitted to a server. The server analyzes the object references and organizes them into a display structure. The display structure is then displayed within the browser, including hyperlinks to allow the user to select a prior system state to which he seeks to return. Preferably, the software construct also manages objects associated with the object reference, for example cookies associated with URLs, in order to assure full definition of the desired state. The display structure may also be provided to browsers distinct from the originating browser.

Abstract: This paper proposes an integrated approach to storm water management and storm water treatment. Today's requirements for capturing and treating the first-flush of storm water can be met with a new device that also controls peak flows over a wide range of storms and uses a net storage volume that is substantially lower than the storage computed by traditional reservoir routing methods. The extention basin debuts here as the most efficient method of reducing peak storm water flows—being far more effective than the retention or detention basins in common use today.

Abstract: A control system, method for control, and control software for operating a startup shift element of an automated motor vehicle transmission or automatic transmission capable of electro-hydraulic or electro-pneumatic actuation with an electronic transmission control device, whereby the startup shift element may be shifted hydraulically or pneumatically in emergency mode even if the electronic control device fails. The control system includes a transmission-independent control module, and a emergency-operation mode shift valve capable of electrical triggering, that controls the hydraulic or pneumatic actuation device of the startup shift element. If the transmission-independent control module fails during transmission emergency-mode operation, the startup shift element is capable of actuation by means of the electrical triggering of the emergency-operation mode shift valve via the transmission-independent control module. This may particularly control a motor-vehicle startup procedure.
