In-Mouth Antenna for Tongue Controlled Wireless Devices: Characteristics and Link-Loss

We have investigated the possibility of using a curved dipole antenna inside the mouth for the tongue controlled wireless devices in 2.45GHz ISM band. These devices can be interfaced with the wheelchair or the computer used by the paraplegic patients. Two antenna placement positions have been investigated: in front of the teeth and behind the teeth. The investigations were done through the FDTD si

Neuropeptide levels in Alzheimer's disease and dementia with frontotemporal degeneration

The CSF levels of somatostatin-LI (SLI), neuropeptide Y (NPY-LI) and Delta Sleep Inducing Peptide (DSIP-LI) have been measured in patients with dementia of Alzheimer type (DAT) and dementia with frontotemporal degeneration of non-Alzheimer type (FTD). The distribution pattern of cortical degeneration differs between these two types of dementia. DAT shows degeneration of mainly temporo-parietal and

Will this be on the exam Ms? The tension between use- and exchange value in higher education and its realtion to forms of learning.

This paper explores discourses in higher education viewing two pairs of concepts, on the one hand, the concepts of use- vs. exchange value and on the other, the concepts of deep vs. surface learning. Drawing on Yrjö Engeströms’ position of use- vs. exchange value, and his elaboration on the activity system, we assert that any component in an activity system combines two inherent forces which compe

Minimax Team Decision Problems

We consider the problem of distributed decision making in a quadratic game between a "team" of players and nature. Each player has limited information that could be different from the other players in the team. We show that if there is a solution to the minimax team problem, then the linear policies are optimal, and we show how to find the linear optimal solution by solving a linear matrix ineq

On impedance matching and bandwidth of compact antenna arrays

We analyze the impact of the matching network on compact MIMO systems. Existing studies have found that the matching network has a significant influence on the performance of multiple antenna systems when the antennas are in close proximity. However, none has examined the wideband case. In this paper, we investigate the wideband performance of four different matching networks for multiple dipole a
