Several studies have reported that spontaneous eye movements occur with visuospatial imagery and that they closely reflect content and spatial relations from an original picture or scene during episodic memory retrieval (e.g., Brandt& Stark, 1997; Johansson, et al., 2006). Nevertheless, the role for these eye movements to “nothing” is elusive and has been debated extensively in current researc
A time domain description of linear macroscopic electromagnetic phenomena is considered. We show that it is always possible to model the constitutive relations with a symmetric, positive definite optical response together with a convolution integral. An initial-boundary value problem is formulated for the macroscopic Maxwell equations together with a reflection operator modeling the exterior regio
Svenskar har under en längre tid besökt internationella kunskapscentra. Redan under medeltiden började hantverkare att göra gesällvandringar på kontinenten och senare reste ingenjörer till ledande industriländer. Dessa grupper kom tillbaka med nya kunskaper som bidrog till att Sverige inte bara kunde hänga med i den teknologiska utvecklingen utan också under perioder tillhöra de ledande länderna.
In 1995, Best et al. published a formula for the exact bit error probability for Viterbi decoding of the rate R=1/2, memory m=1 (2-state) convolutional encoder with generator matrix G(D)=(1 1+D) when used to communicate over the binary symmetric channel. Their method was later extended to the rate R=1/2, memory m=2 (4-state) generator matrix G(D)=(1+D^2 1+D+D^2) by Lentmaier et al. In this paper,
