Abstract:

International Telemetering Conference Proceedings / October 29-November 02, 1990 / Riviera Hotel and Convention Center, Las Vegas, Nevada<br>This paper describes the technical principle that signals conversion, data-processing and data storage are directly carried out without filling up with the reference pulse for PPM and PPK (pulse position keying). By means of analysis for typical frame structure of PPM/PPK signals, a variety of math models of signal time relationship of the system were found, and based on this, a engineering way and a principle block diagram for signals conversion, data pr

Abstract:

Recently, systems that integrate positron emission tomography and magnetic resonance imaging (PET/MR) have become available for clinical use. This new technology, which combines the high spatial resolution and superior soft-tissue contrast of MR with the picomolar sensitivity, quantitative capabilities, and wide array of tracers of PET, has the potential to benefit patients and provide insights that were previously unattainable in standalone systems. Simultaneous measurement of PET and MR parameters provides complementary information, allowing for a more complete assessment of disease, as wel

Abstract:

Medical imaging plays an essential role in current clinical research and practice. Among the wealth of available imaging modalities, Positron Tomography Emission (PET) reveals functional processes in vivo by providing information on the interaction between a biological target and its tracer at the molecular level. A time series of PET images obtained from a dynamic scan depicts the spatio-temporal distribution of the PET tracer. Analysing the dynamic PET data then enables the quantification of the functional processes of interest for disease understanding and drug development. Given the time d

Abstract:

The images in positron emission tomography (PET) represent three dimensional dynamic distributions of biologically interesting molecules labelled with positron emitting radionuclides (radiotracers). Spatial localisation of the radio-tracers is achieved by detecting in coincidence two collinear photons which are emitted when the positron annihilates with an ordinary electron. In order to obtain quantitatively accurate images in PET, it is necessary to correct for the effects of photon attenuation within the subject being imaged. These corrections can be obtained using singles-mode photon transm

The field of app-based PPG monitoring of cardiac activity is promising, yet classification of heart rhythms in normal sinus rhythm (NSR) or atrial fibrillation (Afib) is difficult in the case of noisy measurements.

We evaluate the distributions of three features of our signals: the peak area, amplitude and the time interval between two successive pulses. We evaluate if some factors affected the distribu

To improve efficacy in the field of drug discovery simpler in vivo, non invasive methods such as PET and SPECT are used. Pharmacokinetic analysis is the underlying method for analyzing the PET data. Imaging of tracer distribution is used to study a metabolic process.

Abstract:

Due to the high dimensionality of most biological data, it is a difficult task to directly analyze, model and visualize the data to gain biological insight. Thus, dimensionality reduction becomes an imperative pre-processing step in analyzing and visualizing high-dimensional biological data. Two major approaches to dimensionality reduction in genomic analysis and biomarker identification studies are: Feature extraction, creating new features by combining existing ones based on a mapping technique; and feature selection, choosing an optimal subset of all features based on an objective function.

Abstract:

A common problem within positron emission tomography examinations of the brain is the motion of the patient. If the patients ́ head moves during an examination all the data acquired after the movement will not be suited for clinical use. This means that a lot of data recovered from PET is not used at all. Motion tracking during PET acquisitions of the brain is not a well explored issue within medical imaging in relation to the magnitude of the problem. Due to the radiation risks of the examination and the logistics at the hospital, a second acquisition is not preferred. Therefore a method to a

Abstract:

Få personer säkerhetskopierar tillräckligt ofta, trots att de riskerar att förlora viktiga filer. Vad beror det på? Denna uppsats har genom en kvantitativ undersökning försökt klarlägga vilka faktorer som har störst påverkan på detta beteende och om det finns ett samband mellan dessa. Datainsamlingen skedde genom en enkätundersökning, med över 300 svar från olika studenter på Uppsala universitet. Resultaten analyseras med hjälp av det teoretiska ramverket “Protection Motivation Theory” (PMT) och jämförs sedan med liknande forskning. Resultaten visar att lättja och glömska är de två faktorer so

Abstract:

L'hétérogénéité tumorale est un facteur important de progression et de résistance au traitement. L'imagerie multiparamétrique TEP-IRM offre des opportunités uniques de caractérisation biologique cellulaire, mais n’a jamais été évalué à l’échelle régionale intra-tumorale dans le cancer du poumon non à petites cellules (CBNPC), première cause de décès oncologique. Une approche multiparamétrique dynamique simultanée TEP-IRM au 18F-FDG a été développée en ce sens. Cette approche a nécessité l’implémentation « maison » de la méthode de référence de quantification TEP du métabolisme glucidique (modè

Abstract:

The focus of this thesis is the application of data envelopment analysis to understand and evaluate the performance of diverse animal welfare organizations across the United States. The results include identification of the most efficient animal welfare organizations, at least among those that post statistics on their operations, and a discussion of various partnerships that may improve the performance of the more inefficient organizations. The Humane Society of the United States estimates that there are 4000 - 6000 independently-run animal shelters across the United States, with an estimated
