First the clock frequency and phase differences between pairs of nodes are estimated employing a two-way message exchange protocol. The estimates are further improved in a Kalman filter with a dedicated observation error model. In the second stage network-wide synchronization is achieved by means of a gossiping algorithm which estimates the average clock frequency and phase of the sensor nodes. These averages are viewed as frequency and phase of a virtual master clock, to which the clocks of the sensor nodes have to be adjusted. The amount of adjustment is computed in a specific control loop. While these steps are done in software, the actual sampling rate correction is carried out in hardware by using an adjustable frequency synthesizer. Experimental results obtained from hardware devices and software simulations of large scale networks are presented.}}, author = {{Schmalenstroeer, Joerg and Jebramcik, Patrick and Haeb-Umbach, Reinhold}}, issn = {{0165-1684}}, journal = {{Signal Processing}}, keywords = {{Gossip algorithm}}, pages = {{ -- }}, title = {{{A combined hardware-software approach for acoustic sensor network synchronization }}}, doi = {{http://dx.doi.org/10.1016/j.sigpro.2014.06.030}}, year = {{2014}}, } @inproceedings{11897, abstract = {{ "In this paper we present an approach for synchronizing the sampling clocks of distributed microphones over a wireless network.

To improve synchronization accuracy it has therefore been proposed to employ a Kalman Filter to obtain improved frequency deviation and phase offset estimates. The estimation requires a statistical model of the errors of the measurements obtained from the time stamp exchange algorithm. These errors are caused by random transmission delays and hardware effects and are thus network specific. In this contribution we develop an algorithm to estimate the parameters of the measurement error model alongside the Kalman filter based sampling clock synchronization, employing the Expectation Maximization algorithm. Simulation results demonstrate that the online estimation of the error model parameters leads only to a small degradation of the synchronization performance compared to a perfectly known observation error model."}}, author = {{Schmalenstroeer, Joerg and Zhao, Weile and Haeb-Umbach, Reinhold}}, booktitle = {{11.

This study tested whether switching feedback content has any effects on learning to perform golf putts without full visibility. 60 participants (44 men, 16 women; M age = 26.3 yr., SD = 6.6) practiced golf putts without seeing the ball movement. 30 of the participants were golfers with moderate expertise, and 30 were novices. They received feedback regarding their putts, either on the angle or on the distance in one of three feedback schedules: blocked, serial-blocked, or serial. Independent of the expertise level, learning was not affected by the feedback schedule. The strong linkage between the two components—direction and distance—may have prevented a sufficient level of contextual interference. }}, author = {{Krause, Daniel and Brüne, Alexander and Fritz, Susanne and Kramer, Pascal and Meisterjahn, Peter and Schneider, Michael and Sperber, Alena}}, issn = {{0031-5125}}, journal = {{Perceptual and Motor Skills}}, keywords = {{Sensory Systems, Experimental and Cognitive Psychology}}, number = {{2}}, pages = {{384--399}}, publisher = {{SAGE Publications}}, title = {{{Learning of a Golf Putting Task with Varying Contextual Interference Levels Induced by Feedback Schedule in Novices and Experts}}}, doi = {{10.2466/23.30.pms.118k17w3}}, volume = {{118}}, year = {{2014}}, } @article{48709, author = {{Krause, Daniel and Beck, Frieder and Agethen, Manfred and Blischke, Klaus}}, issn = {{0166-4328}}, journal = {{Behavioural Brain Research}}, keywords = {{Behavioral Neuroscience}}, pages = {{169--173}}, publisher = {{Elsevier BV}}, title = {{{Effect of catechol-O-methyltransferase-val158met-polymorphism on the automatization of motor skills – A post hoc view on an experimental data}}}, doi = {{10.1016/j.bbr.2014.02.037}}, volume = {{266}}, year = {{2014}}, } @article{49015, author = {{Moritz, Tilman}}, journal = {{Ancient Warfare Magazine}}, number = {{5}}, pages = {{9 -- 11}}, title = {{{A History of Victors?
