Improving Image Quality in a multi-plane Compton Telescope for Hadron Therapy Monitoring

2023

Esta disertación explora diferentes técnicas para mejorar la calidad de las imágenes obtenidas con cámaras Compton. Tal mejora es una de las necesidades principales que obstaculizan la aplicación de cámaras Compton como herramientas para la verificación en tiempo real de terapia hadrónica, a través de la obtención de imágenes de distribuciones espaciales de emisión rápida de rayos gamma emitidos como subproductos de las interacciones de estos hadrones en el paciente. Esta aplicación presenta importantes dificultades, pues requiere medir rayos gamma de energías relativamente altas emitidos en un rango de energías amplio y junto a otras partículas no deseadas. Además, la cámara Compton debe s…

Ocena działania preparatu Solcoseryl u chorych po rekonstrukcjach naczyń z powodu krytycznego niedokrwienia kończyn dolnych

2002

Wstęp: Celem pracy była ocena skuteczności leczenia stosowanym dożylnie preparatem Solcoseryl u chorych po rekonstrukcjach naczyń z powodu krytycznego niedokrwienia kończyn dolnych i wyczerpaniu wszystkich możliwości dalszego leczenia chirurgicznego. Założono, że podawanie preparatu Solcoseryl chorym po udanej rekonstrukcji naczyniowej powoduje szybkie ustąpienie bólu i obrzęku, przyspieszenie gojenia się owrzodzeń i demarkację martwicy. Materiał i metody: Do badanej grupy zakwalifikowano 60 chorych leczonych operacyjnie z powodu krytycznego niedokrwienia kończyn dolnych. Średnia wieku wynosiła odpowiednio dla dwóch grup 59,2 i 57,8 roku. Badanie przeprowadzono metodą podwójnie ślepej próby…

Temporal Denoising of Kinect Depth Data

2012

The release of the Microsoft Kinect has attracted the attention of researchers in a variety of computer science domains. Even though this device is still relatively new, its recent applications have shown some promising results in terms of replacing current conventional methods like the stereo-camera for robotics navigation, multi-camera system for motion detection and laser scanner for 3D reconstruction. While most work around the Kinect is on how to take full advantage of its capabilities, so far only a few studies have been carried out on the limitations of this device and fewer that provide solutions to enhance the precision of its measurements. In this paper, we review and analyse curr…

Modelli interoperabili per Cultural Heritage Recording. Le cupole a torrini di Sicilia e Castiglia.

La ricerca indaga l’origine e l’evoluzione di uno specifico modello di cupola su tamburo a pianta circolare o poligonale, con contrafforti cilindrici sull’asse dei piloni della crociera. Sei casi studio in Spagna e in Sicilia sono stati studiati attraverso il riesame delle fonti storiche e sono state analizzate le matrici geometriche sottese al progetto; i casi studio ancora esistenti sono stati rilevati con metodi laser scanning e fotogrammetrici. I modelli tridimensionali sono stati utilizzati per una verifica del contributo statico offerto dai torrini alla stabilità delle strutture. The research work is focused on the origin and the modifications of a peculiar dome on tambour having a ci…

Potres i obnova u Dubrovniku 1520. godine

2015

In 1520 the territory of Ragusa republic was struck by a strong earthquake. According to the documents, all the private houses and also the main religious and public buildings in the city were damaged. The totality of the measures taken from government’s units allow to know the modality of emergency management by a strongly centralized state organization, ensuring at the same time individual freedom and social balance. The effects of earthquake create the necessity of a wide reconstruction work, involving both private and public sphere. The private citizens did mainly emergency interventions, in order to resolve static problems, not taking the opportunity for a restyling of their buildings.…

Determination of absolute internal conversion coefficients using the SAGE spectrometer

2016

A non-reference based method to determine internal conversion coefficients using the SAGE spectrometer is carried out for transitions in the nuclei of 154Sm, 152Sm and 166Yb. The Normalised-Peak-to-Gamma method is in general an efficient tool to extract internal conversion coefficients. However, in many cases the required well-known reference transitions are not available. The data analysis steps required to determine absolute internal conversion coefficients with the SAGE spectrometer are presented. In addition, several background suppression methods are introduced and an example of how ancillary detectors can be used to select specific reaction products is given. The results obtained for …
