Wide field-of-view (FOV) optics are widely used in various imaging, display, and sensing applications. Conventional wide FOV rely on complicated lens assembly comprising multiple elements to suppress coma other Seidel aberrations. The emergence of flat exemplified by metasurfaces diffractive optical (DOEs) offers a promising route expand the without escalating complexity systems. To date, desig...

Several techniques exist to select and materialize a proper set of data in a suitable structure that manage the queries submitted to the online analytical processing systems. These techniques are called view management techniques, which consist of three research areas: 1) view selection to materialize, 2) query processing and rewriting using the materialized views, and 3) maintaining materializ...

The basic theoretical ideas of the handbag mechanism for wide-angle exclusive scattering reactions are discussed and, with regard to the present experimental program carried out at JLab, its application to Compton scattering is reviewed in some detail. Results for other wide-angle reactions such as two-photon annihilations into pairs of hadrons or virtual Compton scattering are presented as well.

The possibility of sharing one’s point of view makes use of wearable cameras compelling. These videos are often long, boring and coupled with extreme shake as the camera is worn on a moving person. Fast forwarding (i.e. frame sampling) is a natural choice for faster video browsing. However, this accentuates the shake caused by natural head motion in an egocentric video, making the fast forwarde...
