Investigation of Meson Production at COSY-TOF Using the Analysis Framework TofRoot
… located at the proton accelerator COSY (Juelich) stands out for experimental versatility. This is due to its modular setup: about ten subdetectors can be be arranged to satisfy the individual requirements of specific experiments. However, this flexibility hampers the calibration and …

Untersuchung der assoziierten Strangenessproduktion in der Reaktion pp->K+Sigma+n mit dem COSY-Flugzeitspektrometer
Am COSY-TOF-Detektor existiert ein umfangreiches Programm zur Untersuchung der assoziierten Strangenessproduktion im Proton-Proton-Stoss. Bei der im April 1998 durchgeführten Messung wurde erstmals die Reaktion pp -> K+ Sigma+ n schwellennah, bei einem Strahlimpuls von 2,85 GeV/c, entsprechend …

Untersuchungen zu den Reaktionen pp-->nK+Sigma+ und pp-->pK0Sigma+
Das Kuehlersynchrotron COSY im Forschungszentrum Juelich kann u.a. einen guten Protonenstrahl fuer Experimente zur Verfuegung stellen. An einem der Experimentierplaetze steht das Flugzeitspektrometer COSY-TOF. Es eignet sich hervorragend zur Untersuchung von Reaktionen, bei denen wenige Teilchen …

High-Resolution Nuclear Magnetic Resonance Microspectroscopy
… quantum filtered correlated spectroscopy (DQF-COSY) allows signals from selected components in the sample to be isolated. Inclusion of gradients in the microcoil probe greatly enhanced DQF-COSY experiments and enabled a host of other selective editing sequences to be run. Finally experimental …

Demonstration and quantitation of lactate in oxidative and glycolytic fibers of skeletal muscles
… the acyl chain of lipid. From both NMR evidence (COSY, lactate editing, and $\sp{13}$C enrichment) and biochemical evidence (including results of electrical, caffeine or high potassium stimulation, and iodoacetate inhibition of glycolysis), both peaks are identified as lactate.

Procedural synthetic data for self-driving cars using 3D graphics
In this thesis we present CoSy, a configurable system for procedurally generating synthetic data for self-driving vehicles. To address the problem of data hungry vision-based learning algorithms used in self-driving vehicles, we develop a system that generates synthetic images, including class …

The Search for New/Unknown Signals
… isotropic liquid. Thus, it was surprising when COSY Revamped by Asymmetric Z-gradient Echo Detection (CRAZED) was first introduced in the early `90s and showed strong iMQC signals. Since then, CRAZED has inspired a wide range of applications for iMQCs and led to two different but equivalent …

Karakterisering van Grubbs-tipe prekatalisatore met behulp van kernmagnetiese resonansspektroskopie
… NMR characterization mainly consists of 1H, 31P, COSY and rarely 13C. Due to the high natural abundance of 1H and 31P (99.98% and 100%), these experiments could be carried out quickly and easily. The only change that had to be made was to the spectral width, to accommodate the carbene signal …

An NMR study of human brain tumours: Phosphorus chemical shift imaging in vivo and high resolution proton spectroscopy of biopsy samples.
… volunteers. One dimensional $\sp1$H spectra, COSY spectra and T$\sb2$ data were obtained from ex vivo biopsy samples. A parameter, P, was defined as the ratio of the area between 3.4 and 3.1. ppm over the area between 1.5 ppm and 1.1 ppm. The parameter distinguished glioblastomas from …

Re-evaluation of analytical chemistry techniques in studying DNA structures
… (NOESY) and correlation spectroscopy (COSY) were used to examine the conformational differences of 2’-deoxyadenosine when incubated in water. From the distance and torsion angle constraints obtained from NOESY and COSY respectively, and from existing crystal structures, it was found the …

Social critique in the major novels of John Wyndham : civilization's secrets and nature's truths
… been dismissed by many critics as a writer of "cosy catastrophes", a term coined by Brian Aldiss. This title is meant to suggest that Wyndham's works are critically insignificant, and that, as Nicholas Ruddick suggests, they do not repay serious critical attention. I would argue that not only do …
