Automated Registration and Fusion of Functional and Anatomical MRI for Navigated (2008)

T. Rohlfing, J. Beier, J. B. West, T. Liebig, C. A. Taschner

Abstract. A procedure for acquisition, automated registration and fusion of functional and anatomical magnetic resonance images (MRI) is presented and validated. The technique is based upon the...

Reduction of Metal Artifacts in Computed Tomographies for the Planning and Simulation of Radiation Therapy (2008)

T. Rohlfing, D. Zerfowski, J. Beier, P. Wust, N. Hosten, R. Felix

Subject was to evaluate techniques for the reduction of metal artifacts in X-ray computed tomographies (CT). Compared to simulated CT projection data, real measurements allowed less improvements in...

Automated Registration and Fusion of Functional and Anatomical MRI for Navigated (2007)

T. Rohlfing, J. Beier, J. B. West, T. Liebig, C. A. Taschner

as an electronic reprint. One print or electronic copy may be made for personal use only. Systematic or multiple reproduction, distribution to multiple locations via electronic or other means,...

New interdigital design for large area dye solar modules using a lead-free glass frit sealing (2006)

Sastrawan, R., Beier, J., Belledin, U., Hemming, S., Hinsch, A., Kern, R., ...

A new interdigital design for large area dye solar modules is developed for an area of 30 x 30 cm(2). This design requires fewer holes in the glass substrate for electrolyte filling, than the...

Time to extinction in relation to mating system and type of density regulation in populations with two sexes (2004)

Saether, BE, Engen, S, Lande, R, Moller, AP, Bensch, S, Hasselquist, D, ...

1. Population viability models usually consider only the female segment of the population. However, random variation in sex ratio as well as the mating system may also affect variation in fitness...

Efficacy and safety of four doses of lumiracoxib versus diclofenac in patients with knee or hip primary osteoarthritis: A phase II, four-week, multicenter, randomized, double-blind, placebo-controlled trial (2004)

Schnitzer, TJ, Beier, J, Hasler, P, Patel, SK, Senftleber, I, Gitton, X, ...

Objective. To compare the efficacy and tolerability of the novel cyclooxygenase 2-selective inhibitor lumiracoxib with placebo and diclofenac in osteoarthritis (OA). Methods. Adults (n = 583) with...

A simulation model of African Anopheles ecology and population dynamics for the analysis of malaria transmission (2004)

Depinay, J. M. O., Mbogo, C. M., Killeen, G., Knols, B.G.J., Beier, J., Carlson, J., ...

Background: Malaria is one of the oldest and deadliest infectious diseases in humans. Many mathematical models of malaria have been developed during the past century, and applied to potential...

Photoluminescence studies of CdS/CdTe solar cells treated with oxygen. (2003)

Hernandez-Fenollosa, M. A., Halliday, D. P., Durose, K., Campo, M. D., Beier, J.

In this work we have used low temperature photoluminescence (PL) to study a set of CdS/CdTe solar cells grown by close space sublimation. The samples were given a post-growth treatment at 390 °C...

Key aspects of CdTe/CdS solar cells. (2002)

Durose, K., Boyle, D., Abken, A., Ottley, C. J ., Nollet, P., Degrave, S., ...

Recent developments in the following areas are briefly reviewed: a) the electrical structure of grain boundaries in CdTe absorbers, b) impurities and non-stoichiometry in CdTe solar cells and c) use...

Comparison of dark and light I-V curves of solar cells (1991)

Beier, J., Bücher, K.

Measurements of I-V-curves of several solar cells at different temperatures and illuminations were made. The results of transferring the fit parameters of the dark measurements to light I-V curves at...

Spectral response measurements of large area solar cells with a filter monochromator system (1989)

Schönecker, A., Beier, J., Zastrow, A.

A computer controlled filter monochromator system (FMS) with 18 interference filters covering the spectral range from 350 nm to 1150 nm will be presented. The emphasis of the paper will be to dicuss...

Uncertainty analysis of PV efficiency measurements with a solar simulator - spectral mismatch, non-uniformity and other sources of error (1988)

Beier, J., Heidler, K.

A detailed uncertainty analysis of the solar simulator method for measuring PV efficiencies of crystalline Si solar cells leads to a 2.3 % uncertainty limit (resp. plus minus 4.4 % for linear...

Präzisionsmeßplatz für den Wirkungsgrad von Solarzellen (1988)

Beier, J., Fischer, H., Heidler, K., Kamps, G., Kunzelmann, S., Zastrow, A.

A new precision measurement facility for solar cell efficiency has been installed with an actual overall measurement uncertainty of plus minus 2,3%. The measurement method and the experimental set-up...
