Die Biodiversität von Vertebraten nimmt weltweit rapide ab, wobei Amphibien die am stärksten gefährdete Wirbeltiergruppe darstellen. In der EU sind 21 von 89 Amphibienarten bedroht. Die intensiv genutzte europäische Agrarlandschaft ist eine der Hauptursachen für diese Rückgänge. Da die Agrarlandschaft einen bedeutenden Lebensraum für Amphibien darstellt, kann die Exposition zu Pestiziden negative Auswirkungen auf Amphibienpopulationen haben. Derzeit erfordert die europäischen Risikobewertung von Pestiziden für Vertebraten spezifische Ansätze für Fische hinsichtlich der aquatischen Vertebratentoxizität und für Vögel sowie Säugetiere in Bezug auf die terrestrische Vertebratentoxizität. Die besonderen Eigenschaften von Amphibien werden jedoch nicht berücksichtigt. Daher war das übergeordnete Ziel dieser Arbeit, die
ökotoxikologischen Effekte von Pestiziden auf mitteleuropäische Froschlurche zu untersuchen. Dazu wurden Effekte auf aquatische und terrestrische Amphibienstadien sowie auf deren Reproduktion untersucht. Anschließend wurden in dieser Arbeit in Erwartung einer Risikobewertung von Pestiziden für Amphibien mögliche regulatorische Risikobewertungsansätze diskutiert.
Für die untersuchten Pestizide und Amphibienarten wurde festgestellt, dass die akute aquatische Toxizität von Pestiziden mit dem bestehenden Ansatz der aquatischen Risikobewertung auf der Grundlage von Fischtoxizitätsdaten abgedeckt werden kann. Jedoch wurden bei terrestrischen Juvenilen nach dermaler Exposition zu umweltrealistischen Pestizidkonzentrationen sowohl letale als auch subletale Effekte beobachtet, die mit keinem verfügbaren Risikobewertungsansatz erfasst werden können. Daher sollten Pestizide vor der Zulassung auch auf eine potenzielle terrestrische Toxizität mit Hilfe von Risikobewertungsinstrumenten geprüft werden. Darüber hinaus müssen die Auswirkungen von Bei- und Hilfsstoffen von Pestiziden bei einer zukünftigen Risikobewertung besonders berücksichtigt werden, da sie die Toxizität von Pestiziden gegenüber aquatischen und terrestrischen Amphibienstadien erhöhen können.
Des Weiteren wurde gezeigt, dass die chronische Dauer einer kombinierten aquatischen und terrestrischen Exposition die Reproduktion von Amphibien negativ beeinflusst. Gegenwärtig
können solche Effekte von der bestehenden Risikobewertung nicht erfasst werden, da Daten aus Feldszenarien, die die Auswirkungen mehrerer Pestizide auf die Reproduktion von Amphibien abbilden, zu selten sind, um einen Vergleich mit Daten anderer terrestrischer Wirbeltiere wie Vögel und Säugetiere zu ermöglichen. In Anbetracht dieser Erkenntnisse sollten sich zukünftige Untersuchungen nicht nur mit akuten und letalen Effekten, sondern auch mit chronischen und subletalen Effekten auf Populationsebene befassen. Da sich die Exposition gegenüber Pestiziden negativ auf Amphibienpopulationen auswirken kann, sollte ihr Einsatz noch sorgfältiger überlegt werden, um einen weiteren Rückgang der Amphibien zu vermeiden. Insgesamt unterstreicht diese Arbeit die dringende Notwendigkeit einer protektiven Pestizidrisikobewertung für Amphibien, um Amphibienpopulationen in Agrarlandschaften zu erhalten und zu fördern.
Most social media platforms allow users to freely express their opinions, feelings, and beliefs. However, in recent years the growing propagation of hate speech, offensive language, racism and sexism on the social media outlets have drawn attention from individuals, companies, and researchers. Today, sexism both online and offline with different forms, including blatant, covert, and subtle lan- guage, is a common phenomenon in society. A notable amount of work has been done over identifying sexist content and computationally detecting sexism which exists online. Although previous efforts have mostly used peoples’ activities on social media platforms such as Twitter as a public and helpful source for collecting data, they neglect the fact that the method of gathering sexist tweets could be biased towards the initial search terms. Moreover, some forms of sexism could be missed since some tweets which contain offensive language could be misclassified as hate speech. Further, in existing hate speech corpora, sexist tweets mostly express hostile sexism, and to some degree, the other forms of sexism which also appear online was disregarded. Besides, the creation of labeled datasets with manual exertion, relying on users to report offensive comments with a tremendous effort by human annotators is not only a costly and time-consuming process, but it also raises the risk of involving discrimination under biased judgment.
This thesis generates a novel sexist and non-sexist dataset which is constructed via "UnSexistifyIt", an online web-based game that incentivizes the players to make minimal modifications to a sexist statement with the goal of turning it into a non-sexist statement and convincing other players that the modified statement is non-sexist. The game applies the methodology of "Game With A Purpose" to generate data as a side-effect of playing the game and also employs the gamification and crowdsourcing techniques to enhance non-game contexts. When voluntary participants play the game, they help to produce non-sexist statements which can reduce the cost of generating new corpus. This work explores how diverse individual beliefs concerning sexism are. Further, the result of this work highlights the impact of various linguistic features and content attributes regarding sexist language detection. Finally, this thesis could help to expand our understanding regarding the syntactic and semantic structure of sexist and non-sexist content and also provides insights to build a probabilistic classifier for single sentences into sexist or non-sexist classes and lastly find a potential ground truth for such a classifier.
In IT-Systemen treten viele Datenschutzrisiken auf, wenn Datenschutzbedenken in den frühen Phasen des Entwicklungsprozesses nicht angemessen berücksichtigt werden. Die Datenschutz-Grundverordnung (DSGVO) schreibt das Prinzip des Datenschutz durch Technikgestaltung (PbD) vor. PbD erfordert den Schutz personenbezogener Daten von Beginn des Entwicklungsprozesses an, durch das frühzeitige Integrieren geeigneter Maßnahmen. Bei der Realisierung von PbD ergeben sich nachfolgende Herausforderungen: Erstens benötigen wir eine präzise Definition von Datenschutzbedenken. Zweitens müssen wir herausfinden, wo genau in einem System die Maßnahmen angewendet werden müssen. Drittens ist zur Auswahl geeigneter Maßnahmen, ein Mechanismus zur Ermittlung der Datenschutzrisiken erforderlich. Viertens müssen bei der Auswahl und Integration geeigneter Maßnahmen, neben den Risiken, die Abhängigkeiten zwischen Maßnahmen und die Kosten der Maßnahmen berücksichtigt werden.
Diese Dissertation führt eine modellbasierte Methodik ein, um die oben genannten Herausforderungen zu bewältigen und PbD zu operationalisieren. Unsere Methodik basiert auf einer präzisen Definition von Datenschutzbedenken und umfasst drei Untermethodiken: modellbasierte Datenschutzanalyse, modellbasierte Datenschutz-Folgenabschätzung und datenschutzfreundliche Systemmodellierung. Zunächst führen wir eine Definition für Datenschutzpräferenzen ein, anhand derer die Datenschutzbedenken präzisiert werden können und überprüft werden kann, ob die Verarbeitung personenbezogener Daten autorisiert ist. Zweitens präsentieren wir eine modellbasierte Methodik zur Analyse eines Systemmodells. Die Ergebnisse dieser Analyse ergeben die Menge der Verstöße gegen die Datenschutzpräferenzen in einem Systemmodell. Drittens führen wir eine modellbasierte Methode zur Datenschutzfolgenabschätzung ein, um konkrete Datenschutzrisiken in einem Systemmodell zu identifizieren. Viertens schlagen wir in Bezug auf die Risiken, Abhängigkeiten zwischen Maßnahmen und Kosten der Maßnahmen, eine Methodik vor, um geeignete Maßnahmen auszuwählen und in ein Systemdesign zu integrieren. In einer Reihe von realistischen Fallstudien bewerten wir unsere Konzepte und geben einen vielversprechenden Ausblick auf die Anwendbarkeit unserer Methodik in der Praxis.
Knowledge-based authentication methods are vulnerable to Shoulder surfing phenomenon.
The widespread usage of these methods and not addressing the limitations it has could result in the user’s information to be compromised. User authentication method ought to be effortless to use and efficient, nevertheless secure.
The problem that we face concerning the security of PIN (Personal Identification Number) or password entry is shoulder surfing, in which a direct or indirect malicious observer could identify the user sensitive information. To tackle this issue we present TouchGaze which combines gaze signals and touch capabilities, as an input method for entering user’s credentials. Gaze signals will be primarily used to enhance targeting and touch for selecting. In this work, we have designed three different PIN entry method which they all have similar interfaces. For the evaluation, these methods were compared based on efficiency, accuracy, and usability. The results uncovered that despite the fact that gaze-based methods require extra time for the user to get familiar with yet it is considered more secure. In regards to efficiency, it has the similar error margin to the traditional PIN entry methods.
Wir analysieren versionsbasierte Softwareprojekte, um den Entwicklern API- und Domänen-Wissen zuzuordnen. Genauer gesagt analysieren wir die einzelnen Commits in einem Repository in Hinblick auf die API-Nutzung. Auf dieser Grundlage können wir APIs (oder Teile davon) den Entwicklern zuordnen und dadurch auf die API-Erfahrung der Entwickler schließen. Im transitiven Schluss können wir auf Domänen-Erfahrung schließen, da jeder API eine Programmierdomäne zugewiesen wird.
Human action recognition from a video has received growing attention in computer vision and has made significant progress in recent years. Action recognition is described as a requirement to decide which human actions appear in videos. The difficulties involved in distinguishing human actions are due to the high complexity of human behaviors as well as appearance variation, motion pattern variation, occlusions, etc. Many applications use human action recognition on captured video from cameras, resulting in video surveillance systems, health monitoring, human-computer interaction, and robotics. Action recognition based on RGB-D data has increasingly drawn more attention to it in recent years. RGB-D data contain color (Red, Green, and Blue (RGB)) and depth data that represent the distance from the sensor to every pixel in the object (object point). The main problem that this thesis deals with is how to automate the classification of specific human activities/actions through RGB-D data. The classification process of these activities utilizes a spatial and temporal structure of actions. Therefore, the goal of this work is to develop algorithms that can distinguish these activities by recognizing low-level and high-level activities of interest from one another. These algorithms are developed by introducing new features and methods using RGB-D data to enhance the detection and recognition of human activities. In this thesis, the most popular state-of-the-art techniques are reviewed, presented, and evaluated. From the literature review, these techniques are categorized into hand-crafted features and deep learning-based approaches. The proposed new action recognition framework is based on these two categories that are approved in this work by embedding novel methods for human action recognition. These methods are based on features extracted from RGB-D data that are
evaluated using machine learning techniques. The presented work of this thesis improves human action recognition in two distinct parts. The first part focuses on improving current successful hand-crafted approaches. It contributes into two significant areas of state-of-the-art: Execute the existing feature detectors, and classify the human action in the 3D spatio-temporal domains by testing a new combination of different feature representations. The contributions of this part are tested based on machine learning techniques that include unsupervised and supervised learning to evaluate this suitability for the task of human action recognition. A k-means clustering represents the unsupervised learning technique, while the supervised learning technique is represented by: Support Vector Machine, Random Forest, K-Nearest Neighbor, Naive Bayes, and Artificial Neural Networks classifiers. The second part focuses on studying the current deep-learning-based approach and how to use it with RGB-D data for the human action recognition task. As the first step of each contribution, an input video is analyzed as a sequence of frames. Then, pre-processing steps are applied to the video frames, like filtering and smoothing methods to remove the noisy data from each frame. Afterward, different motion detection and feature representation methods are used to extract features presented in each frame. The extracted features
are represented by local features, global features, and feature combination besides deep learning methods, e.g., Convolutional Neural Networks. The feature combination achieves an excellent accuracy performance that outperforms other methods on the same RGB-D datasets. All the results from the proposed methods in this thesis are evaluated based on publicly available datasets, which illustrate that using spatiotemporal features can improve the recognition accuracy. The competitive experimental results are achieved overall. In particular, the proposed methods can be better applied to the test set compared to the state-of-the-art methods using the RGB-D datasets.
Efficient Cochlear Implant (CI) surgery requires prior knowledge of the cochlea’s size and its characteristics. This information helps to select suitable implants for different patients. Registered and fused images helps doctors by providing more informative image that takes advantages of different modalities. The cochlea’s small size and complex structure, in addition to the different resolutions and head positions during imaging, reveals a big challenge for the automated registration of the different image modalities. To obtain an automatic measurement of the cochlea length and the volume size, a segmentation method of cochlea medical images is needed. The goal of this dissertation is to introduce new practical and automatic algorithms for the human cochlea multi-modal 3D image registration, fusion, segmentation and analysis. Two novel methods for automatic cochlea image registration (ACIR) and automatic cochlea analysis (ACA) are introduced. The proposed methods crop the input images to the cochlea part and then align the cropped images to obtain the optimal transformation. After that, this transformation is used to align the original images. ACIR and ACA use Mattes mutual information as similarity metric, the adaptive stochastic gradient descent (ASGD) or the stochastic limited memory Broyden–Fletcher–Goldfarb–Shanno (s-LBFGS) optimizer to estimate the parameters of 3D rigid transform. The second stage of nonrigid registration estimates B-spline coefficients that are used in an atlas-model-based segmentation to extract cochlea scalae and the relative measurements of the input image. The image which has segmentation is aligned to the input image to obtain the non-rigid transformation. After that the segmentation of the first image, in addition to point-models are transformed to the input image. The detailed transformed segmentation provides the scala volume size. Using the transformed point-models, the A-value, the central scala lengths, the lateral and the organ of corti scala tympani lengths are computed. The methods have been tested using clinical 3D images of total 67 patients: from Germany (41 patients) and Egypt (26 patients). The atients are of different ages and gender. The number of images used in the experiments is 217, which are multi-modal 3D clinical images from CT, CBCT, and MRI scanners. The proposed methods are compared to the state of the arts ptimizers related medical image registration methods e.g. fast adaptive stochastic gradient descent (FASGD) and efficient preconditioned tochastic gradient descent (EPSGD). The comparison used the root mean squared distance (RMSE) between the ground truth landmarks and the resulted landmarks. The landmarks are located manually by two experts to represent the round window and the top of the cochlea. After obtaining the transformation using ACIR, the landmarks of the moving image are transformed using the resulted transformation and RMSE of the transformed landmarks, and at the same time the fixed image landmarks are computed. I also used the active length of the cochlea implant electrodes to compute the error aroused by the image artifact, and I found out an error ranged from 0.5 mm to 1.12 mm. ACIR method’s RMSE average was 0.36 mm with a standard deviation (SD) of 0.17 mm. The total time average required for registration of an image pair using ACIR was 4.62 seconds with SD of 1.19 seconds. All experiments are repeated 3 times for justifications. Comparing the RMSE of ACIR2017 and ACIR2020 using paired T-test shows no significant difference (p-value = 0.17). The total RMSE average of ACA method was 0.61 mm with a SD of 0.22 mm. The total time average required for analysing an image was 5.21 seconds with SD of 0.93 seconds. The statistical tests show that there is no difference between the results from automatic A-value method and the manual A-value method (p-value = 0.42). There is no difference also between length’s measurements of the left and the right ear sides (p-value > 0.16). Comparing the results from German and Egypt dataset shows there is no difference when using manual or automatic A-value methods (p-value > 0.20). However, there is a significant difference when using ACA2000 method between the German and the Egyptian results (p-value < 0.001). The average time to obtain the segmentation and all measurements was 5.21 second per image. The cochlea scala tympani volume size ranged from 38.98 mm3 to 57.67 mm3 . The combined scala media and scala vestibuli volume size ranged from 34.98 mm 3 to 49.3 mm 3 . The overall volume size of the cochlea should range from 73.96 mm 3 to 106.97 mm 3 . The lateral wall length of scala tympani ranged from 42.93 mm to 47.19 mm. The organ-of-Corti length of scala tympani ranged from 31.11 mm to 34.08 mm. Using the A-value method, the lateral length of scala tympani ranged from 36.69 mm to 45.91 mm. The organ-of-Corti length of scala tympani ranged from 29.12 mm to 39.05 mm. The length from ACA2020 method can be visualised and has a well-defined endpoints. The ACA2020 method works on different modalities and different images despite the noise level or the resolution. In the other hand, the A-value method works neither on MRI nor noisy images. Hence, ACA2020 method may provide more reliable and accurate measurement than the A-value method. The source-code and the datasets are made publicly available to help reproduction and validation of my result.
Soziale Medien bieten eine leistungsstarke Möglichkeit für Menschen, Meinungen und Gefühle zu einem bestimmten Thema auszutauschen, sodass andere von diesen Gedanken und Gefühlen profitieren können. Dieses Verfahren erzeugt eine riesige Menge an unstrukturierten Daten, wie Texte, Bilder und Verweise, die durch täglich anwachsende Kommentare zu verwandten Diskussionen ständig zunimmt. Die riesige Menge an unstrukturierten Daten stellt jedoch ein Risiko für den Prozess der Informationsextraktion dar, sodass die Entscheidungsfindung zu einer großen Herausforderung wird. Dies liegt daran, dass die Datenflut zu einem Verlust von nützlichen Daten aufgrund ihrer unangemessenen Darstellung und ihrer Anhäufung führen kann. Insofern leistet diese Arbeit einen Beitrag zum Gebiet der Sentimentanalyse und des Opinion Mining, das darauf abzielt, Emotionen und Meinungen aus riesigen Text- und Bilddatensätzen zu extrahieren. Das ultimative Ziel ist es, jeden Text oder jedes Bild als Ausdruck einer positiven, negativen oder neutralen Emotion zu klassifizieren, um bei der Entscheidungsfindung zu helfen. Sentiment- und Meinungsklassifikatoren wurden für Text- und Bilddatensätze aus sozialen Medien entwickelt, z. B. für Firmen- oder Produktbewertungen, Blogbeiträge und sogar Twitter-Nachrichten. In dieser Arbeit wird zunächst eine neue Methode zur Reduktion der Dimension von Textdaten auf Basis von Data-Mining-Ansätzen vorgestellt und anschließend das Sentiment auf Basis von neuronalen und Deep Neural Network-Klassifikationsalgorithmen untersucht. Anschließend untersuchen wir im Gegensatz zur Sentiment-Analyseforschung in Textdatensätzen die Sentiment Ausdrucks- und Polaritätsklassifikation innerhalb und über Bilddatensätze hinweg, indem wir tiefe neuronale Netze auf Basis des Aufmerksamkeitsmechanismus aufbauen.
The bio-insecticide Bacillus thuringiensis israelensis (Bti) has worldwide become the most commonly used agentin mosquito control programs that pursue two main objectives: the control of vector-borne diseases and the reduction of nuisance, mainly coming frommosquitoes that emerge in large quantities from seasonal wetlands. The Upper Rhine Valley, a biodiversity hotspot in Germany, has been treated withBti for decades to reduce mosquito-borne nuisance and increase human well-being.Although Btiis presumed to be an environmentally safe agent,adverse effects on wetland ecosystems are still a matter of debate especially when it comes to long-term and indirect effects on non-target organisms. In light of the above, this thesis aims at investigating direct and indirect effects of Bti-based mosquito control on non-target organisms within wetland food chains.Effects were examinedin studies with increasingeco(toxico)logical complexity, ranging from laboratory over mesocosm to field approaches with a focus on the non-biting Chironomidae and amphibian larvae (Rana temporaria, Lissotriton sp.).In addition, public acceptance of environmentally less invasive alternative mosquito control methods was evaluated within surveys among the local population.
Chironomids were the most severely affected non-target aquatic invertebrates. Bti substantially reduced larval and adult chironomid abundances and modified their species composition. Repeated exposures to commonly used Bti formulations induced sublethal alterations of enzymatic biomarkers activityin frog tadpoles. Bti-induced reductions of chironomid prey availability indirectly decreased body size of newts at metamorphosis and increased predation on newt larvae in mesocosm experiments. Indirect effects of severe reductions in midge biomassmight equally be passed through aquatic but also terrestrial food chains influencing predators of higher trophic levels. The majority ofaffectedpeople in the Upper Rhine Valley expressed a high willingness to contributefinancially to environmentally less harmful mosquito control.Alternative approaches could still include Bti applications excepting treatment of ecologically valuable areas. Potentially rising mosquito levels could be counteracted with local acting mosquito traps in domestic and urban areas because mosquito presence was experienced as most annoying in the home environment.
As Bti-based mosquito control can adversely affect wetland ecosystems, its large-scale applications, including nature conservation areas, should be considered more carefully to avoid harmful consequences for the environmentat the Upper Rhine Valley.This thesis emphasizesthe importance to reconsiderthe current practice of mosquito control and encourage research on alternative mosquito control concepts that are endorsed by the local population. In the context ofthe ongoing amphibian and insect declinesfurther human-induced effects onwetlands should be avoided to preserve biodiversity in functioning ecosystems.
Aktuelle Schätzungen bestätigten, dass Binnengewässer eine erhebliche Menge Methan (CH4) und Kohlendioxid (CO2) sowohl auf regionaler Ebene, als auch global freisetzen. Jedoch basieren diese Schätzungen auf extrapolierten gemessenen Daten, ungenügender Auflösung der räumlich-zeitlichen Variabilität und es mangelt an Daten aus ariden und semi-ariden Gebieten, sowie den Kohlestoffquellen aus Kläranlagen.
Für die hier vorliegende Studie analysierten wir monatliche hydrologische und meteorologische Daten sowie Daten zur Wasserqualität von drei Stauseen aus dem Gebiet des unteren Jordans, die zur Trinkwassergewinnung und zur Bewässerung genutzt werden, und schätzten damit deren Emissionsrate an CO2 ab. Wir untersuchten den Effekt von Kläranlagen auf die umliegenden Gewässer im Hinblick auf CH4 und CO2-Emissionen indem wir saisonal aufgelöste Daten der Konzentration der beiden gelösten Gase in Kläranlagenauslässen und in Vorflutern von neun Kläranlagen in Deutschland analysierten. Mithilfe von Low-Cost-Methoden die die CO2-Transportrate und die Ausgasungsrate über Gasblasen messen, untersuchten wir die räumliche und zeitliche Variabilität der CH4 und CO2-Emissionen von aquatischen Süßwasser-Ökosystemen.
Unsere Schätzungen zeigen, dass Stauseen in semi-ariden Regionen CO2 übersättigt sind und somit CO2 an die Atmosphäre abgeben, also eine Netto-Quelle sind.
Die Größenordnung der beobachteten Transportraten der drei jordanischen Stauseen ist vergleichbar mit denen von tropischen Stauseen (3,3 g CO2 m-2 Tag-1). Die CO2-Emissionsrate ist abhängig von Änderungen der Wasseroberfläche, welche durch den Betrieb der Stauseen verursacht sind. Kläranlagen entlassen eine beachtlichen Menge an CH4 (30.9±40.7 kg Jahr-1) und CO2 (0.06±0.05 Gg Jahr-1) in ihre umgebenden Flüsse und Bäche. Deren Emissionsraten sind durch diese Einleitung der Kläranlagen um 1,2-fach für CH4 oder 8,6-fach für CO2 erhöht. Unsere Ergebnisse zeigen, dass sowohl die diffusive als auch die Gasblasenemissionsrate räumlich und zeitlich variabel ist, weshalb beide Emissionsraten bei zukünftigen Studien auch in der nötigen Auflösung gemessen werden sollten.
Wir schlussfolgern, dass bei zukünftigen Emissionsmessungen und –schätzungen von Binnengewässern auch die Gewässerbewirtschaftung, die Kohlenstoffquelle von Kläranlagen und die räumliche und zeitliche Variabilität der Emissionen beachtet werden sollten.
