Abstract: A system, computer readable medium and method trains a video transformer, using a machine learning engine, for human action recognition in a video. The method includes sampling video clips with varying temporal resolutions in global views and sampling the video clips from different spatiotemporal windows in local views. The machine learning engine is configured to match the global and local views in a framework of student-teacher networks to learn cross-view correspondence between local and global views, and to learn motion correspondence between varying temporal resolutions. The video transformer can output for display video clips in a manner that emphasizes attention to the recognized human action.

Abstract: A rapid method of synthesizing nanoflowers made of nanoflakes of nickel molybdate (NiMoO4) directly on nickel foam (NF) through an aerosol-assisted chemical vapor deposition (AACVD) process is disclosed. The nickel molybdate nanoflowers were grown on NF by varying the deposition time for 60 and 120 min at a fixed temperature of 480° C. and their efficiency was investigated as oxygen evolution reaction (OER) catalysts in 1 M KOH electrolyte. The NiMoO4 nanoflowers of NF obtained after 60 minutes of AACVD process showed OER performance with lowest overpotential of 320 mV to reach standard current density of 10 mA cm?2. The catalyst continuously performed the OER for 15 h, signifying its prominent stability under electrochemical conditions.

Abstract: A wireless device (e.g., a cell phone) having a first SIM card for a first (e.g., private) wireless network and a second SIM card for a second (e.g., public) wireless network. The wireless device disables searching for the first wireless network if its current location is outside of a defined coverage region for the first wireless network, thereby saving battery power. The defined coverage region may be defined by minimum and maximum longitude and latitude values that superscribe the overall coverage area of the first wireless network. The network server for the first wireless network transmits a definition of a defined coverage region for the wireless network and automatically updates the defined coverage region when the overall coverage area of the first wireless network is modified, such as when a new access point is added to the network.
