  • Publication number: 20230368230
    Abstract: A tool, method, and system for assessing an incremental value of one or more items in an item assortment are disclosed. The tool can receive historical purchasing data, which can include a plurality of customers purchasing one or more items of a plurality of items in an item assortment. The tool can use the historical purchasing data for the plurality of customers to simulate execution of removal of an item from the item assortment, wherein removal of the item from the item assortment causes an incremental loss associated with the item. The tool can order any number of items of the historical purchasing data. The tool can execute scenario simulations, and the tool can account for probabilities when interacting with the historical purchasing data. The tool can display assessment data and receive inputs via an interactive user interface. The tool can launch the assessment data in a downstream application.

  • Patent number: 10200542
    Abstract: Systems and computing devices may be configured to intelligently and dynamically allocate quotas for the access and use of a telecommunications network by consumers that use a shared account balance. A server computing device may be configured to intelligently allocate quota by determining an allocation time interval for allocating quota from a shared account balance, receiving a quota request message from a metering and gating component that includes information requesting allocation of a first quota to a first consumer associated with a shared account balance, determining a validity period for the first quota based on the determined allocation time interval, and allocating the first quota to the first consumer from the updated shared account balance so as to eliminate or reduce conflicts and discrepancies between different instances of the shared account balance.

  • Patent number: 9952938
    Abstract: Methods, devices and systems enable restoring a database system more efficiently. A server computing device may be configured to determine a recovery time interval for a session store database system so as to allow a large number of sessions (e.g., ninety percent of sessions, etc.) to start and finish within that interval, periodically review database records to identify a database record that has not been updated within a most recent recovery time interval, add the identified database record to a journaling log, and update the identified database record to include information identifying a time at which the database record was last added to the journaling log. After detecting a failure event, the server computing device may perform the database operations identified in the journaling log to restore the database system.

  • Publication number: 20060165747
    Abstract: An activator comprising a biocompatible base and a known fungicide in the form of an acid salt are mixed together by the user shortly before being applied to the infection so as to react them chemically to produce the free base of the fungicide thereby rendering the composition capable of penetrating throughout the infected tissue. The free base form has been found to be much more lethal to the fungal infection, particularly in the treatment of onychomycosis. The activator is formulated to be mixed within a few days of or just before application with the fungicide, e.g., terbinafine hydrochloride (an acid salt). Although the free base is subject to degradation and has a shorter shelf life, it was found that mixing just prior to use eliminates problems that could be caused by degradation of an active ingredient. A preferred activator solution also contains a penetration enhancer and a tissue softener.
