Indiana University-Purdue University Indianapolis (IUPUI) / Physicians receive multiple CCDs for a single patient encompassing various encounters and medical history recorded in different information systems. It is cumbersome for providers to explore different pages of CCDs to find specific data which can be duplicated or even conflicted. This study describes the steps towards a system that integrates multiple CCDs into one consolidated document for viewing or processing patient-level data. Also, the impact of the system on healthcare providers’ perceived workload is evaluated. A modular system is developed to consolidate and de-duplicate CDA-based documents. The system is engineered to be scalable, extensible and open source. The system’s performance and output has evaluated first based on synthesized data and later based on real-world CCDs obtained from INPC database. The accuracy of the consolidation system along with the gaps in identification of the duplications were assessed. Finally, the impact of the system on healthcare providers’ workload is evaluated using NASA TLX tool. All of the synthesized CCDs were successfully consolidated, and no data were lost. The de-duplication accuracy was 100% based on synthesized data and the processing time for each document was 1.12 seconds. For real-world CCDs, our system de-duplicated 99.1% of the problems, 87.0% of allergies, and 91.7% of medications. Although the accuracy of the system is still very promising, however, there is a minor inaccuracy. Due to system improvements, the processing time for each document is reduced to average 0.38 seconds for each CCD. The result of NASA TLX evaluation shows that the system significantly decreases healthcare providers’ perceived workload. Also, it is observed that information reconciliation reduces the medical errors. The time for review of medical documents review time is significantly reduced after CCD consolidation. Given increasing adoption and use of Health Information Exchange (HIE) to share data and information across the care continuum, duplication of information is inevitable. A novel system designed to support automated consolidation and de-duplication of information across clinical documents as they are exchanged shows promise. Future work is needed to expand the capabilities of the system and further test it using heterogeneous vocabularies across multiple HIE scenarios.

In the newspaper printing industry, offset is the dominating printing method and the use of multicolour printing has increased rapidly in newspapers during the last decade. The offset printing process relies on the assumption that an uniform film of ink of right thickness is transferred onto the printing areas. The quality of reproduction of colour images in offset printing is dependent on a number of parameters in a chain of steps and in the end it is the amount and the distribution of ink deposited on the substrate that create the sensation and thus the perceived colours. We identify three control points in the offset printing process and present methods for assessing the printing process quality in two of these points: • Methods for determining if the printing plates carry the correct image • Methods for determining the amount of ink deposited onto the newsprint A new concept of colour impression is introduced as a measure of the amount of ink deposited on the newsprint. Two factors contribute to values of the colour impression, the halftone dot-size and ink density. Colour impression values are determined on gray-bars using a CCD-camera based system. Colour impression values can also be determined in an area containing an arbitrary combination of cyan magenta and yellow inks. The correct amount of ink is known either from a reference print or from prepress information. Thus, the deviation of the amount of ink can be determined that can be used as control value by a press operator or as input to a control system. How a closed loop controller can be designed based on the colour impression values is also shown. It is demonstrated that the methods developed can be used for off-line print quality monitoring and ink feed control, or preferably in an online system in a newspaper printing press. / <p>Report code: LiU-TEK-LIC-2005:02.</p>

Los dispositivos CCDs (por las siglas en inglés de Charge Coupled Devices) son aún hoy en día la tecnología líder para la toma de imágenes de baja distorsión y son ampliamente utilizados en aplicaciones de astronomía en el rango de la luz visible y en el infrarrojo cercano. En esta tesis se estudia y desarrolla su utilización para la detección de otras partículas diferentes a los fotones de luz, en particular para partículas con muy poca probabilidad de detección y muy poca deposición de energía logrando que esta nueva tecnología presente una ventaja respecto a detectores disponibles hoy en día. Los resultados de esta tesis son la base del desarrollo de una aplicación de un sistema de CCDs para la detección de neutrinos provenientes de un reactor nuclear. Se estudian las características principales de los CCDs que los hacen aptos para esta novedosa aplicación, y se encuentra que la mayor limitante de su rendimiento es el ruido de lectura agregado por su etapa de salida. Se desarrolla una técnica para reducir su incidencia, y mejorar así la capacidad de detección. A partir de estas características se analiza la capacidad de los CCD para detectar neutrinos provenientes de un reactor nuclear por medio de la interacción coherente entre el neutrino y los núcleos de los átomos de silicio. Para optimizar la detección de eventos de este tipo en las imágenes de salida, se deriva un modelo matemático que estudia el mecanismo de generación de carga en el CCD y se desarrolla una técnica de calibración que permite obtener información de la profundidad a la que se produce la ionización Estos resultados se plasmaron en el desarrollo de un prototipo instalado en la Central Nuclear Almirante Álvaro Alberto, en Angra dos Reis, Brasil. Se muestran algunos resultados preliminares obtenidos con este prototipo, y se comentan las mejoras que se realizarán próximamente en este sistema. / Charge Coupled Devices are still nowadays the best available technology for low distortion digital imaging applications and are extensively used for ground and spacebased astronomy for visible light and near infrared. In this thesis, studies to extent its use to applications for the detection of particles different to light photons are presented, in particular for those particles having low probability of interaction and small deposition of energy for which this technology presents advantages over available detectors. These studies are the base for the development of a CCD system aiming the detection of low energy neutrinos coming out from a nuclear reactor. The most important aspects of scientific CCDs for particle detection are revisited, and its main detection limitation produced by the readout noise added by the output amplifier of the device is explained. A technique to reduce the effect of this noise and to improve the detection performance is developed. The main features of CCDs are then used to analyze the feasibility of detecting low energy neutrinos through their coherent scattering with nuclei. A mathematical model of the expected signal in the output images is obtained and a new technique for the calibration of the CCDs to obtained the depth of the interaction in the silicon is developed. This result is used to improve the detection performance of the system The first CCD system prototype for this application is presented together with some details of its installation at Central Nuclear Almirante Alvaro Alberto in Angra dos Reis, Brazil, and some preliminary results are discuSSED.

The Virginia Tech Spectral-Line Survey (VTSS) is a high sensitivity, high resolution survey of Hydrogen-$\alpha$ and Sulfur-II emission in the full northern hemisphere. The instrument used for the survey is the Spectral Line Imaging Camera (SLIC). SLIC uses a fast(f/1.2) lens attached to a cryogenically cooled, TK 512x512 CCD with 27 micron pixels. The focal length of the lens is 58mm which gives a pixel size of 1.6 arcminutes. The diameter of each field is 10degrees. A filter wheel ahead of the lens allows for imaging at different wavelengths. Automating the imaging system is desirable and advantageous due to the large scope of the survey. A variety of devices have been developed in order to implement automation of the SLIC observatory. They include an automated focusing mechanism, filter wheel, liquid nitrogen auto fill system, motorized roll-off roof, cloud monitor, and an equatorial mount. A PERL script, called SLICAR (Spectral Line Imaging Camera Automation Routine), was written to control and communicate with the various hardware and software components. The program also implements a user prepared Observing File, and makes decisions based on observing conditions. / Master of Science

Actuellement, les mesures de dose en radiothérapie sont effectuées en employant différents types de détecteurs tels que les chambres à ionisation, les diodes et les films radiosensibles. Bien que ces différents détecteurs permettent d’obtenir une mesure de dose très précise, aucun d’entre eux n’a les propriétés nécessaires pour permettre la mesure de dose en temps réel sur un patient tout en ne perturbant pas le champ radiatif de traitement. Depuis une vingtaine d’années, les scintillateurs plastiques gagnent en popularité grâce à leurs propriétés relativement identiques à celles de l’eau, et du fait qu’ils génèrent un signal lumineux proportionnel à la dose déposée. Cette étude vise à construire un dispositif CCD sans lentilles pour la collecte de la lumière de scintillation, pour ensuite caractériser le signal obtenu et comparer le tout à un système optique plus conventionnel à base de lentilles. Pour ce faire, nous avons conçu un détecteur à fibre scintillante ayant servi pour l’acquisition des mesures des deux systèmes étudiés, soit le système à objectif photographique et le système équipé d’un « taper » à fibre optique. Nous avons évalué les signaux mesurés en termes de qualité par le ratio de signal sur bruit, en limite minimale de dose mesurable, en stabilité et en reproductibilité des mesures. Les résultats obtenus démontrent la supériorité du nouveau système sans lentille sur le système conventionnel en termes de gain de collecte de photon et en diminution des incertitudes de mesures. Ces résultats ouvrent la voie à des applications de mesure de très faibles doses et à la réduction des dimensions des détecteurs à des fins d’applications cliniques « in vivo », ou encore pour effectuer divers tests de contrôle de qualité des appareils.

Les objets spatiaux en basse orbite dont les satellites et les débris spatiaux représentent une menace croissante; leur vitesse relative fait que même les plus petits représentent un potentiel danger pour les infrastructures spatiales. Alors que les instruments optiques et radars permettent une bonne couverture des débris de grande taille (> 1 m), la population de débris spatiaux proche du centimètre est mal représentée dans les catalogues. Le suivi de ces objets implique l'utilisation d'un imageur fixe sur des observatoires ou des satellites à la recherche d'objets en mouvement, mais cette solution est coûteuse et le temps d'accessibilité est limité selon le nombre de projets. Une alternative est d'utiliser les ballons stratosphériques pour l'observation du ciel avec un détecteur capable d'effectuer des acquisitions rapides, empêchant ainsi le signal faible de l'objet d'être noyé dans le signal du bruit de fond. Ce projet de recherche se concentre sur l'observation de cette population de débris, en utilisant une caméra *Electron Multiplying Charge Coupled Device*, Hnü512 de Nüvü Caméras, avec sa capacité de comptage de photons et une fréquence d'acquisition rapide, dans le domaine du visible sur un ballon stratosphérique à 35-40 km d'altitude. Le lancement du ballon stratosphérique a été effectué le 22 août 2023 à la base de lancement de l'Agence Spatiale Canadienne, à Timmins, Ontario. Ce document présente les différentes phases de la conception d'une charge utile et une analyse d'une séquence d'empilement d'un objet en mouvement sur 113 acquisitions avec un champ de vue de 2,347°, un temps d'exposition de 4,5 ms et un gain EM de 2500. De plus, ce projet est en collaboration avec le projet HiCIBaS-II, un télescope pour l'observation directe d'exoplanète par imagerie à haut contraste embarqué sur un ballon. Ce travail contribue à l'effort global sur la connaissance de la situation spatiale en évaluant l'impact de l'inclusion de l'imagerie optique embarquée dans les systèmes de détection sur ballon. / Low-orbit space objects represent a growing threat ; their relative speed means that even the smallest objects are a potential danger to space infrastructures. While optical and radar instruments provide good coverage of large debris objects (> 1 m), the near-centimeter space debris population is poorly represented in catalogs. Tracking these objects involves searching for moving objects using a fixed imager on observatories or satellites, but this solution is costly and time is limited by the number of astronomical projects. An alternative is to use stratospheric balloons for sky observation, with a detector capable of making short exposures, thus preventing the object's weak signal from being drowned out by the background signal. This research project focuses on observing this debris population, using an Electron Multiplying Charge Coupled Device camera, Hnü512 from Nüvü Cameras, with its photon-counting capability and fast frame rate, in the visible range on a stratospheric balloon at 35-40 km altitude. The stratospheric balloon was launched on August 22, 2023 from the Canadian Space Agency's launch pad in Timmins, Ontario. This document presents the various phases involved in designing a payload and an analysis of a stacking sequence of a moving object over 113 acquisitions with a field of view of 2.347°, an exposure time of 4.5 ms and an EM gain of 2500. In addition, this project is in collaboration with the HiCIBaS-II project, a balloon-borne telescope for direct observation of exoplanets using high-contrast imaging. This work contributes to the global effort on space situational awareness by assessing the impact of including onboard optical imaging in balloon-based detection systems.

The Web of Science (WOS) of Thomson Reuters ISI is one of the most well-known citation databases in the world, and the Scopus of Elsevier is also a famous citation databases. In addition, the Mainland China has also developed Chinese Social Sciences Citation Index (CSSCI) database and Chinese Citation Database (CCD) since recent twenty years. Under the sponsorship of the National Science Council in Taiwan, the Taiwan Social Science Research Center established the Taiwan Social Sciences Citation Index (TSSCI) database in 1996 and the Center for Humanities Research built up Taiwan Humanities Citation Index (THCI) database in 1999. On the other hand, Airiti Incorporation has developed Academic Citation Index (ACI). However, the application of TSSCI, THCI and ACI reveals many design flaws and use limitations for both databases, some search functions are different and not available, and it is therefore difficult for users to get information through the same search interface. It is truly important to construct an integrate citation index database for Taiwan humanity and social science researchers. Working with an information service company, the purpose of the present study is to propose a design plan to establish a Taiwan humanity and social science citation database. 　　The following issues will be investigated in this study: 1. Collecting source literature and citation literature from humanity and social science journals publishing by Taiwan academic institutes. 2. Designing the structure of citation index system, types and contents of the database. 3. Setting up the standards for description on database fields. 4. Developing the basic, advanced and other information retrieval functions. 5. Seeking for the integration with WoS to fulfill the goal of information resources sharing and the promotion of global visualization. 6. Building the quantitative indicator for evaluating the humanity and social science research.
