This paper introduces the EMMA model of eye movements and visual attention. EMMA provides a formal model of the temporal and spatial aspects of eye movements as they arise from shifts in visual attention. To implement the model, EMMA is integrated into the ACT-R/PM cognitive architecture (Anderson & Lebiere, 1998) and requires minimal modification of existing ACT-R/PM models. This paper details...

Consequent application of the instantaneous approximation to both the interaction and all propagators of the bound-state constituents allows us to forge, within the framework of the Bethe–Salpeter formalism for the description of bound states, an instantaneous form of the Bethe–Salpeter equation with exact (i.e., full) propagators of the bound-state constituents. This instantaneous equation gen...

We show, by means of a perturbative weakly nonlinear analysis, that the axisymmetric magneto-rotational instability (MRI) in a magnetic Taylor-Couette (mTC) flow in a thin-gap gives rise, for very small magnetic Prandtl numbers (Pm), to a real Ginzburg-Landau equation for the disturbance amplitude. The saturation amplitude As is found to scale in this regime as P m, with 1/2 < δ < 2/3 (dependin...

In this paper, the sizing equation analyses are presented for two different radial and axial flux field controlled PM machines. These types of machines have two sources of excitation which allows one to easily control the airgap flux. Variable flux component provided by the field winding and fixed flux component obtained from PM converge into the airgap so that an additive or subtractive effect...

We consider a nonlinear partial differential equation for complexvalued functions which is related to the two-dimensional stationary Schrödinger equation and enjoys many properties similar to those of the ordinary differential Riccati equation as, e.g., the famous Euler theorems, the Picard theorem and others. Besides these generalizations of the classical “one-dimensional” results we discuss n...

It is shown that, by an appropriate modification of the structure of the interaction potential, the Breit equation can be incorporated into a set of two compatible manifestly covariant wave equations, derived from the general rules of Constraint Theory. The complementary equation to the covariant Breit type equation determines the evolution law in the relative time variable. The interaction pot...

The mixing angle θ13 is the last mixing angle to be measured. A non-zero value of θ13 is key to the possibility of measuring CP violation in future long-baseline accelerator experiments. The best limit on θ13 comes from the reactor experiment CHOOZ.[1] It has recently been recognized that the best possibility for rapidly measuring a non-zero value of the parameter θ13 comes from a new reactor e...
