Readers of a certain age may remember classic American Express advertising campaign from the seventies. As reported in [1] , line ‘Don’t leave Home Without It’ got its start “in series ads where fedora wearing Karl Malden warned about dangers carrying cash instead Tr...

The current study explored media use and media multitasking activities among college students in Kuwait based on the results of a cross-sectional survey (N=179). The study examined what types of media students in Kuwait use the most, with which media they multitask the most, and what multitasking pairs are the most common. It was also explored how media ownership, sensation seeking, and demogra...

Knowledge-based authentication (e.g. passwords) has long been associated with a vulnerability to shoulder surfing ; being stolen by attackers overlooking the interaction. In order to combat such threats, steps can be taken to either alter the form of the challenge made to the user, or make use of an interaction technique that is resistant to information leakage. We consider the latter, and empi...

We discuss that energetic electrons are generated near the X-type magnetic reconnection region due to a surfing acceleration mechanism. In a thin plasma sheet, the polarization electric fields pointing towards the neutral sheet are induced around the boundary between the lobe and plasma sheet in association with the Hall electric current. By using a particle-in-cell simulation, we demonstrate t...

Electron injection process at high Mach number collisionless quasi-perpendicular shock waves is investigated by means of one-dimensional electromagnetic particle-in-cell simulations. We find that energetic electrons are generated through the following two steps : (1) electrons are accelerated nearly perpendicular to the local magnetic field by shock surfing acceleration at the leading edge of t...

This paper presents a novel variation of wave pipelining that we call “surfing.” In previous wave pipelined designs, timing uncertainty grows monotonically as events propagate through gates or other logic elements. We bound this dispersion by propagating a timing pulse along with the data values. Our logic elements have delays that are smaller in the presence of the pulse than in its absence. T...
