Using gaze is a popular way to design concepts for Human-Computer-Interaction (HCI). It is especially often used for remote or hands-free communication with for example public displays, devices within smart homes or smart watches. With the introduction of Pursuits, a new technique, that exploits the smooth pursuit eye movement, was presented. It overcomes the need for calibration before working...

A practical real frequency technique for broadband impedance matching is based on bilinear reflection behavior versus lumped and distributed element variables. An efficient grid search locates a likely-global solution so that a precise constrained gradient optimization can eliminate unnecessary elements in candidate networks.

The armed forces and the army are main elements of national power. Military readiness gives real significance to the geography, natural resources, and industrial power. Military elements of national power include military purposes, military doctrines, military strategies and policies (defensive and non-defensive), forces, training, command, military technology, weapons and equipment, military o...

We present and analyze new multifocal optical elements based on an annular distribution of the transmittance. These elements provide selectable number of foci and can be designed to work between two fixed positions or even to provide extended focal depth. The energy of the foci can be modulated through a single parameter that controls the area of each ring. In our study we analyze the quality o...

Prompted by the recent better determination of the angles of the unitarity triangle, we re-appraise the problem of finding simple fermion mass textures, possibly linked to some symmetry principle and compatible with grand unification. In particular, the indication that the angle α is close to rectangle turns out to be the crucial ingredient leading us to single out fermion mass textures whose e...
