Full textThis thesis investigated the potential open data as a complementary resource for Anomaly Detection (AD) in the Maritime Surveillance (MS) domain. A framework for AD was proposed based on the usage of open data sources along with other traditional sources of data. According to the proposed AD framework and the algorithms for implementing the expert rules, the Open Data Anomaly Detection System (ODADS) was developed. To evaluate the accuracy of the system, an experiment on the vessel traffic data was conducted and an accuracy of 99% was obtained for the system. There was a false negative case in the system results that decreased the accuracy. It was due to incorrect AIS data in a special situation that was not possible to be handled by the detection rules in the scope of this thesis. The validity of the results was investigated by the subject matter experts from the Swedish Coastguard. The validation results showed that the majority of the ODADS evaluated anomalies were true alarms. Moreover, a potential information gap in the closed data sources was observed during the validation process. Despite the high number of true alarms, the number of false alarms was also considerable that was mainly because of the inaccurate open data. This thesis provided insights into the open data as a complement to the common data sources in the MS domain and is concluded that using open data will improve the efficiency of the surveillance systems by increasing the accuracy and covering some unseen aspects of maritime activities.

Full textMänniskor delar mer och mer på social medier medvetna om att de blir övervakade, men omedvetna om i vilken utsträckning och på vilka sätt datan är processad. Idag används mycket resurser för att urföra dessa uppgifter. Med det här projektet visar vi att det är möjligt att samla in, processa och spara data från sociala medierna Reddit och Twitter i realtid genom att enbart använda en persondator. Vårat fokus har varit att använda ansiktsigenkänning för att identifiera specifika individer från en dataström, men datan kan användas för andra syften. Vi har också kollat på de etiska dilemman som dyker upp i samband med insamling och processning av sådan data.

In this thesis, we describe the use of medical insurance claims data in three important areas of medicine. First, we develop expert- trained statistical models of quality of care based on variables derived from insurance claims. Such models can be used to identify patients who are receiving poor care so that interventions can be arranged to improve their care. Second, we develop an algorithm that utilizes claims data to perform post-marketing surveillance of drugs to detect previously unknown side effects. The algorithm performed strongly in several realistic simulation tests, detecting side effects a large fraction of the time while controlling the false detection rate. Lastly, we use insurance claims data to improve our understanding of the costs of care for patients who suffer from depression and a chronic disease.

Full textThis paper discusses the telemetry processing and data verification performed by the SBV Processing, Operations and Control Center (SPOCC) located at MIT Lincoln Laboratory (MIT LL). The SPOCC is unique among the Midcourse Space Experiment (MSX) Data Processing Centers because it supports operational demonstrations of the SBV sensor for Space-Based Space Surveillance applications. The surveillance experiment objectives focus on tracking of resident space objects (RSOs), including acquisition of newly launched satellites. Since Space Surveillance operations have fundamentally short timelines, the SPOCC must be deeply involved in the mission planning for the series of observations and must receive and process the resulting data quickly. In order to achieve these objectives, the MSX Concept of Operations (CONOPS) has been developed to include the SPOCC in the operations planning process. The SPOCC is responsible for generating all MSX spacecraft command information required to execute space surveillance events using the MSX. This operating agreement and a highly automated planning system at the SPOCC allow the planning timeline objectives to be met. In addition, the Space Surveillance experiment scenarios call for active use of the 1 Mbps real-time link to transmit processed targets tracks from the SBV to the SPOCC for processing and for short time-line response of the SPOCC to process the track of the new object and produce new commands for the MSX spacecraft, or other space surveillance sensors, to re-acquire the object. To accomplish this, surveillance data processed and stored onboard the SBV is transmitted to the APL Mission Processing Center via 1 Mbps contacts with the dedicated Applied Physics Laboratory (APL) station, or via one of the AFSCN RTS locations, which forwards the telemetry in real-time to APL. The Mission Processing facility at APL automatically processes the MSX telemetry to extract the SBV allocation and forwards the data via file transfer over a dedicated fractional T1 link to the SPOCC. The data arriving at the SPOCC is automatically identified and processed to yield calibrated metric observations of RSOs. These results are then fed forward into the mission planning process for follow-up observations. In addition to the experiment support discussed above, the SPOCC monitors and stores SBV housekeeping data, monitors payload health and status, and supports diagnosis and correction. There are also software tools which support the assessment of the results of surveillance experiments and to produce a number of products used by the SBV instrument team to assess the overall performance characteristics of the SBV instrument.

Full textTiivistelmä Videovalvonnassa on tapahtunut viime vuosina merkittävää kasvua johtuen järkyttävistä tapahtumista kuten terrori-iskut, pankkiryöstöt ja järjestäytyneen rikollisuuden toimet. Videovalvontateknologia on kehittynyt merkittävästi mahdollistaen jopa yksittäisten ihmisten automaattisen seurannan. Turvallisuuden lisääntymisen katsotaan kuitenkin vähentäneen yksityisyyttä. Videovalvonnan avulla ihmisiä pystytään seuraamaan helpommin kuin koskaan aikaisemmin tunkeutuen täten heidän yksityisyytensä alueelle. On oletettu, että turvallisuus ja yksityisyys videovalvonnassa on nollasummapeliä, jossa kansalaisten on valittava yksityisyyden ja turvallisuuden välillä. Tämä tutkimus perustuu olettamukseen, että edellä esitetty ei pidä paikkaansa, vaan että on mahdollista suojata yksityisyys samalla taaten täysi turvallisuus. Ratkaisua tähän ongelmaan etsittiin suunnittelutieteellisen tutkimuksen avulla. Työssä suunniteltiin ja toteutettiin videovalvontajärjestelmä PEVS (Privacy Enhancing Video Surveillance system), joka suojaa valvonnanalaisten sivullisten yksityisyyttä ja siitä huolimatta tuottaa korkean turvallisuustason.. PEVS suojaa henkilöiden yksityisyyttä salaamalla automaattisesti videoaineistosta ne kuva-alat, joissa esiintyy ihmisiä. Mikäli laitonta toimintaa havaittaisiin, olisi riittävillä käyttöoikeuksilla mahdollista purkaa salaus mielenkiinnon kohteena olevien henkilöiden kohdalta tilanteen analysoimiseksi. Tämä mahdollisti yhtäältä puuttumattomuuden sivullisten yksityisyyteen ja toisaalta tiedon käyttämisen todistusaineistona mahdollisen rikoksen tutkimisessa. Tällä järjestelmällä yksityisyys oli mahdollista suojata samanaikaisesti, kun turvallisuudesta huolehdittiin. PEVS mahdollisti ensimmäistä kertaa maailmassa videovalvonnan, joka näyttää vain relevantit henkilöt jättäen muiden henkilöllisyyden paljastamatta. Sen takia tämän tutkimuksen merkittävin kontribuutio oli uudenlaisen lähestymistavan kehittäminen videovalvontaan, joka kykenee valikoivasti suojelemaan ihmisten yksityisyyttä. Tämä ratkaisu sisältää yksityisyyden suojaavan, useita rakenneosia sisältävän videovalvontajärjestelmäarkkitehtuurin esittelyn. Rakenneosiin kuuluu yksityisen tiedon tallennusmenetelmiä ja varjontunnistus- ja segmentointimetodeja, jotka paransivat aiemmin käytettyjen metodien tarkkuutta ja nopeutta. Lisäksi esiteltiin uudenlainen turvallisuus- ja yksityisyysmetriikka videovalvonnalle. Toteutettu järjestelmä on huomattava lisäys nykytietämykseen, jossa yksityisyyden suojan osalta on otettu vasta ensiaskelia ja joka ei mahdollista kattavaa järjestelmää

Full textIntroduction: La température moyenne mondiale va augmenter de 0,2 º C dans la prochaine décennie. Les effets de cette hausse sur la santé humaine sont inconnus mais peuvent inclure une augmentation des populations des hôtes ou des vecteurs de maladies à transmission vectorielle. Cette étude a été entreprise pour évaluer l'effet qu'une variabilité de la température de la surface de la mer (TSM) aurait sur les cas de leishmaniose, une maladie à transmission vectorielle, au Pérou, ainsi que pour étudier les moyens de modéliser cette relation.Méthodes: L'incidence mensuelle de la leishmaniose cutanée ou cutanéo-muqueuse entre 2002 et 2008 a été combinée avec les anomalies de TSM de l'indice des régions El Niño 1 et 2 (ENI1+2) ou des stations côtières fixes de surveillance. Plusieurs modèles bayésiens ont été comparés en utilisant le critère d'information de déviance (DIC) comme mesure de la qualité de l'ajustement. Le décalage entre l'augmentation de TSM et la hausse ou la baisse de l'incidence de la leishmaniose a été choisi en minimisant le DIC.Résultats: Le modèle qui a donné le meilleur ajustement aux données était un modèle binomial négatif hiérarchique qui avait un terme de tendance linéaire et une fonction cosinus pour modéliser l'incidence de la maladie. Dans ce modèle, chaque degré Celsius au-dessus de la température prévue par les stations de surveillance de TSM donnait une augmentation de l'incidence nationale de la leishmaniose cutanée de 5% cinq mois plus tard (risque relatif 1,05; 95% CI 0,93 à 1,18); chaque degré Celsius au-dessus de la température prévue par ENI1+2 avait comme résultat une augmentation de l'incidence nationale de la leishmaniose cutanée de 26% six mois plus tard (risque relatif 1,26; 95% IC 1,18 à 1,35). Les estimations des effets régionaux variaient beaucoup plus dans le modèle qui utilisait les stations de TSM que dans le modèle basé sur ENI1+2. En général, les régions dans le nord-est avaient des risques relatifs plus élevés que celles du sud. Les résultats pour la leishmaniose cutanéo-muqueuse avaient des intervalles de confiance beaucoup plus larges, mais ils suivaient les mêmes tendances que ceux de la leishmaniose cutanée.Conclusions: Les modèles binomiaux négatifs hiérarchiques qui modèlent le caractère saisonnier de l'incidence avec une fonction cosinus fournissent une bonne qualité d'ajustement aux données de la leishmaniose. Nos résultats indiquent que le réchauffement régional peut contribuer à une augmentation de la transmission de la leishmaniose au Pérou.

Full textCONTEXTE La surveillance des maladies infectieuses est un défi en constante évolution et un progrès continu au niveau des méthodes et des infrastructures est nécessaire pour répondre à la demande. Une nouvelle approche est la surveillance syndromique, où le personnel de santé publique, assisté de collecte automatisée de données et d'alertes statistiques, surveille des indicateurs de santé en temps quasi-réel. Plusieurs systèmes de surveillance syndromique s'appuient sur les diagnostics issus de bases de données administratives. Parce que ces codes de diagnostics ne font pas l'objet d'audits, l'effet de variations dans leur codage sur les définitions syndromiques demeure inconnu. OBJECTIFS 1) Évaluer la faisabilité d'identifier des syndromes à partir des diagnostics issus des services facturés par les médecins. 2) Évaluer l'exactitude de définitions syndromiques basées sur les diagnostics issus des services facturés par les médecins.3) Identifier les caractéristiques du médecin, du patient, de la rencontre médecin-patient et du mode de facturation associées au coefficient de prédiction positif (CPP) des définitions syndromiques. MÉTHODES & RÉSULTATS ÉTUDE 1: Cette étude a porté sur un seul syndrome (respiratoire). Nous avons comparés les cas positifs et négatifs identifiés à partir de la facturation, aux dossiers médicaux. Un échantillon de 9 médecins généralistes Montréalais a été utilisé. Les diagnostics de 3 526 visites effectuées par 729 patients ont été extraits des dossiers médicaux, et reliés à la facturation. La sensibilité et le CPP des diagnostics d'infection respiratoire issus de la facturation étaient 0.49 et 0.93. Cette étude de faisabilité a permis la planification d'une validation à grande-échelle de plusieurs définitions syndromiques. ÉTUDE 2: Cette étude a porté sur 5 syndromes: fièvre, gastro-intestinal, neurologique, cutané et respiratoire. Nous avons sélectionné aléatoirement 3600 médecins pratiquant au Québec en 2005-2007 et, parmi tous les services facturés, 10 visites par médecin. Pour chaque visite, le diagnostic du dossier médical a été obtenu grâce à une révision de dossier à double insu. La sensibilité, la spécificité, le CPP et le coefficient prédictif négatif (CPN) des définitions syndromiques basées sur les diagnostics issus de la facturation ont été estimés. 1098 (30.5%) médecins ont participé à l'étude et 10529 visites ont été validées. La sensibilité des définitions syndromiques variait de 0.11 pour la fièvre à 0.44 pour le syndrome respiratoire. La spécificité et le CPN étaient élevés pour tous les syndromes. Le CPP variait de 0.59 pour la fièvre à 0.85 pour le syndrome respiratoire. ÉTUDE 3: Nous avons restreint notre échantillon aux 4330 visites des 1098 médecins de l'étude 2 où le diagnostic de la facturation correspondait à l'un des syndromes. Nous avons utilisé une régression logistique multi-variée afin d'estimer l'association entre l'accord facturation-dossier et les caractéristiques du médecin, du patient, de la rencontre médecin-patient et du mode de facturation. La probabilité que le dossier médical confirme un syndrome présent selon la facturation était plus élevée lorsque le médecin avait facturé plusieurs visites pour le même syndrome récemment, avait une charge de travail moindre, et lorsque le patient était plus jeune et moins défavorisé socialement. CONCLUSIONS Cette étude a été la première validation à grande-échelle de définitions syndromiques basées sur les diagnostics issus des services facturés par les médecins. Nous avons découvert que la sensibilité de ces définitions est faible, le CPP varie de moyen à élevé, et la spécificité et le CPN sont élévés. Nous avons identifiés maintes caractéristiques du médecin, du patient, de la rencontre médecin-patient et du mode de facturation associées au CPP des définitions syndromiques, dont plusieurs sont accessibles aux agences de santé publique et pourraient être utilisées pour améliorer les systèmes de surveillance syndromique.

Full textThis thesis describes the conceptualisation, development and implementation of a mortuary-based system for the routine collection of information about homicide. It traces the evolution of the system from its conceptualisation in 1994, through various iterations as a city-level research tool, to a national sentinel system pilot, as a multicity all-injury surveillance system, and finally its institutionalisation as a provincial injury mortality surveillance system in the Western Cape. In so doing, it demonstrates that the data arising from medico-legal post-mortem investigations described in this thesis were an important source of descriptive epidemiological information on homicide. The 37,037 homicide records described in the thesis were drawn from Cape Town, Durban, Johannesburg, Port Elizabeth and Pretoria, for which the surveillance system maintained full coverage from 2001 to 2005. The aim was to apply more complex statistical analysis and modelling than had been applied previously.

Location tracking systems in healthcare produce a wealth of data applicable across many aspects of care and management. However, since dedicated location tracking systems, such as the oft mentioned RFID tracking system, are still sparsely deployed, a number of other data sources may be utilized to serve as a proxy for physical location, such as barcodes and manual timestamp entry, and may be better suited to indicate progress through clinical workflows. INCOMING!, a web-based platform that monitors and tracks patient progress from the operating room to the post-anesthesia care unit (PACU), is one such system that utilizes manual timestamps routinely entered as standard process of care in the operating room in order to track a patient's progress through the post-operative period. This integrated real time system facilitates patient flow between the PACU and the surgical ward and eases PACU workload by reducing the effort of discharging patients.
(cont.) We have also developed a larger-scale integrated system for perioperative processes that integrates perioperative data from anesthesia and surgical devices and operating room (OR) / hospital information systems, and projects the real-time integrated data as a single, unified, easy to visualize display. The need to optimize perioperative throughput creates a demand for integration of the datastreams and for timely data presentation. The system provides improved context-sensitive information display, improved real-time monitoring of physiological data, real-time access to readiness information, and improved workflow management. These systems provide improved data access and utilization, providing context-aware applications in healthcare that are aware of a user's location, environment, needs, and goals.

Full textMonitoring, control and surveillance (MCS) of marine fisheries are critical issues for the sustainable management of marine fisheries. In this thesis we investigate the space-based monitoring of fishing vessel activities using Vessel Monitoring System (VMS) trajectory data in the context of INDESO project (2013-2017). Our general objective is to develop a processing chain of VMS data in order to: i) perform a follow-up of the fishing effort of the Indonesian longline fleets, ii) detect illegal fishing activities and assess their importance. The proposed approach relies on classical latent class models, namely Gaussian Mixture Models (GMM) and Hidden Markov Models (HMM), with a view to identifying elementary fishing vessel behaviors, such as travelling, searching and fishing activities, in a unsupervised framework. Following state-of-the-art approaches, we consider different parameterizations of these models with a specific focus on Indonesian longliners, for which we can benefit from at-sea observers¿ data to proceed to a quantitative evaluation. We then exploit these statistical models for two different objectives: a) the discrimination of different fishing fleets from fishing vessel trajectories and the application to the detection and assessment of illegal fishing activities, b) the assessment of a spatialized fishing effort from VMS data. We report good recognition rate (about 97%) for the former task and our experiments support the potential for an operational exploration of the proposed approach. Due to limited at-sea observers¿ data, only preliminary analyses could be carried out for the proposed VMS-derived fishing effort. Beyond potential methodological developments, this thesis emphasizes the importance of high-quality and representative at-sea observer data for further developing the exploitation of VMS data both for research and operational issues
