In order to help journalists investigate inside large audiovisual archives, as maintained by news broadcast agencies, the multimedia data must be indexed by text-based search engies. By automatically creating a transcript through automatic speech recognition (ASR), the spoken word becomes accessible to text search, and queries for keywords are made possible. But stil, important contextual information like the identity of the speaker is not captured. Especially when gathering original footage in the political domain, the identity of the speaker can be the most important query constraint, although this name may not be prominent in the words spoken. It is thus desireable to have this information provided explicitely to the search engine. To provide this information, the archive must be an alyzed by automatic Speaker Identification (SID). While this research topic has seen substantial gains in accuracy and robustness over last years, it has not yet established itself as a helpful, large-scale tool outside the research community. This thesis sets out to establish a workflow to provide automatic speaker identification. Its application is to help journalists searching on speeches given in the German parliament (Bundestag). This is a contribution to the News-Stream 3.0 project, a BMBF funded research project that addresses accessibility of various data sources for journalists.
We present a new interface for interactive comparisons of more than two alternative documents in the context of a generative design system that uses generative data-flow networks defined via directed acyclic graphs. To better show differences between such networks, we emphasize added, deleted, (un)changed nodes and edges. We emphasize differences in the output as well as parameters using highlighting and enable post-hoc merging of the state of a parameter across a selected set of alternatives. To minimize visual clutter, we introduce new difference visualizations for selected nodes and alternatives using additive and subtractive encodings, which improve readability and keep visual clutter low. We analyzed similarities in networks from a set of alternative designs produced by architecture students and found that the number of similarities outweighs the differences, which motivates use of subtractive encoding. We ran a user study to evaluate the two main proposed difference visualization encodings and found that they are equally effective.
Das autonome Fahren wird die Mobilität revolutionieren. Um die Auswirkung der Vollautomation auf dieEigenschaften der Verkehrsmittel und die Präferenzen der Nutzer besser zu verstehen, haben wir dieNutzenwerte neuen Verkehrsmodi im Vergleich zu den bestehenden Verkehrsmodi analysiert und imRahmen einer Online-Umfrage von potentiellen Nutzern in Form eines vollständigen Paarvergleichsbewerten lassen. Die Studie zeigt, dass der Privat-PKW, unabhängig davon ob traditionell odervollautomatisiert, zwar nach wie vor das präferierte Verkehrsmittel ist, im direkten Vergleich das Carsharingjedoch viel stärker von der Vollautomation profitiert. Darüber hinaus gibt es Hinweise darauf, dass dasvollautomatisierte Carsharing verstärkt in Konkurrenz zum ÖPNV tritt.
In diesem Artikel wird darüber berichtet, ob die Glaubwürdigkeit von Avataren als mögliches Modulationskriterium für die virtuelle Expositionstherapie von Agoraphobie in Frage kommt. Dafür werden mehrere Glaubwürdigkeitsstufen für Avatare, die hypothetisch einen Einfluss auf die virtuelle Expositionstherapie von Agoraphobie haben könnten sowie ein potentielles Expositionsszenario entwickelt. Die Arbeit kann innerhalb einer Studie einen signifikanten Einfluss der Glaubwürdigkeitsstufen auf Präsenz, Kopräsenz und Realismus aufzeigen.
Recent approaches in scaffold engineering for bone defects feature hybrid hydrogels made of a polymeric network (retains water and provides light and porous structures) and inorganic ceramics (add mechanical strength and improve cell-adhesion). Innovative scaffold materials should also induce bone tissue formation and incorporation of stem cells (osteogenic differentiation) and/or growth factors (inducing/supporting differentiation). Recently, purinergic P2X and P2Y receptors have been found to significantly influence the osteogenic differentiation process of human mesenchymal stem cells (hMSC). (1) Aim of this work is to develop polysaccharide (PS) composites to be used as scaffolds containing complementary receptor ligands to enable guided stem cell differentiation towards bone formation.
Elektronik für Entscheider
(2017)
Dieses Buch gibt Nichtingenieuren, die sich beruflich mit Elektronik beschäftigen, die Möglichkeit, sich ein Stück auf dieses Fachgebiet zu begeben, um Aufgaben, Sprache und Vorgehensweise von Ingenieuren zu verstehen. Ziel ist es dabei nicht, nach dem Lesen dieses Buches eine elektronische Schaltung entwickeln zu können. Im Vordergrund steht vielmehr ein generelles Verständnis für die Zusammenhänge und Grundbegriffe der Elektronik.
Die Detektion von Explosivstoffen stellt ein zentrales Feld der zivilen Sicherheitsforschung dar. Eine besondere Herausforderung liegt hierbei in dem Nachweis verpackter Substanzen, wie es bei Unkonventionellen Spreng- und Brandvorrichtung (USBV) häufig der Fall ist. Derzeit eingesetzte Verfahren arbeiten meist mit bildgebenden Techniken, durch die sich ein Anfangsverdacht ergibt. Der tatsächliche chemische Inhalt der USBV lässt sich jedoch nicht exakt ermitteln. Eine genaue Beurteilung der Gefährdung durch solche Substanzen ist allerdings von großer Bedeutung, insbesondere wenn die Entschärfung des Objekts in bewohntem Gebiet stattfinden muss. In der vorliegenden Arbeit wird ein Verfahren vorgestellt, das sich als Verifikationsverfahren bei bestehendem Anfangsverdacht gezielt einsetzen lässt. Hierzu wird mittels Laserbohrtechnik zunächst die äußere Hülle des zu untersuchenden Gegenstandes durchdrungen. Anschließend finden eine lasergestützte Probenahme des Inhalts sowie die Detektion unter Verwendung geeigneter Analysemöglichkeiten statt. Der Bohr- und Probenahmefortschritt wird über verschiedene spektroskopische und sensorische Verfahren begleitend überwacht. Zukünftig soll das System abstandsfähig auf Entschärfungsrobotern eingesetzt werden.
Controlling und Leadership: Überlegungen im Kontext der Unternehmensnachfolge in Familienunternehmen
(2017)
Advances in computer graphics enable us to create digital images of astonishing complexity and realism. However, processing resources are still a limiting factor. Hence, many costly but desirable aspects of realism are often not accounted for, including global illumination, accurate depth of field and motion blur, spectral effects, etc. especially in real‐time rendering. At the same time, there is a strong trend towards more pixels per display due to larger displays, higher pixel densities or larger fields of view. Further observable trends in current display technology include more bits per pixel (high dynamic range, wider color gamut/fidelity), increasing refresh rates (better motion depiction), and an increasing number of displayed views per pixel (stereo, multi‐view, all the way to holographic or lightfield displays). These developments cause significant unsolved technical challenges due to aspects such as limited compute power and bandwidth. Fortunately, the human visual system has certain limitations, which mean that providing the highest possible visual quality is not always necessary. In this report, we present the key research and models that exploit the limitations of perception to tackle visual quality and workload alike. Moreover, we present the open problems and promising future research targeting the question of how we can minimize the effort to compute and display only the necessary pixels while still offering a user full visual experience.
Marketing und Innovation
(2017)
Innovation und Marketing zählen zu den zentralen Herausforderungen für Unternehmen, durch die sie Differenzierung und Vorsprung im Wettbewerb erzielen können. Innovation ohne Marketing und Marketing ohne Innovation können nicht erfolgreich sein, weshalb beide Unternehmerfunktionen im Zusammenspiel zu betrachten sind. Das vorliegende Lehrbuch verfolgt deshalb ein zusammenschauendes Konzept, zu dem es das theoretische und praktische Grundlagenwissen vermittelt. Zunächst wird die Bedeutung von Innovation und Marketing als Erfolgsfaktor analysiert. Anschließend wird ein marketingfokussierter Innovationsprozess diskutiert, bei dem auf jeder Stufe die Frage nach der Marktakzeptanz gestellt wird und der ausgeweitet ist auf die Marktausbreitung von Innovationen (Diffusion) sowie die Problematik der Innovationsakzeptanz.
Do remittances and social assistance transfers have different impacts on household’s expenditure patterns? While two separate strands of literature have looked at how social assistance or remittances have been spent, few studies have compared them directly. Using data from a household survey conducted in Moldova in 2011, this paper assesses the impact both types of transfers have on household expenditure patterns. Contrary to the common assumption that money is fungible, we find that social assistance and remittances have different impacts on expenditure patterns (having controlled for potential endogeneity). In other words, where the income comes from can determine how it is spent. As such, different sources of income may have different poverty impacts. In our sample, the two types of transfers are received by different, but slightly overlapping population groups. The fact that the two transfers are spent in different ways means that, to some extent, social assistance and remittances are complements rather than substitutes.
Die Erfindung betrifft eine elektrische Insektenabwehrvorrichtung (1) zur Abwehr kriechender Insekten (2) umfassend eine Spannungserzeugungseinrichtung (4a, 4b) zur Erzeugung einer Abwehrspannung sowie umfassend zumindest zwei nebeneinander angeordnete und beabstandet zueinander verlaufende blanke elektrische Leiter (5a, 5b, 5c, 5d), die derart mit der Spannungserzeugungseinrichtung (4a, 4b) verbunden sind, dass die Abwehrspannung zwischen ihnen liegt. Die elektrischen Leiter sind als flache Leiterbahnen (5a, 5b, 5c, 5d) auf oder in der Oberfläche eines gemeinsamen Trägers (12, 13, 50, 60) ausgebildet, so dass ein Insekt (2) bei einem Berühren der Leiterbahnen (5a, 5b, 5c, 5d) einen elektrischen Schlag erhält.
A deployment of the Vehicle-2-Vehicle communication technology according to ETSI is in preparation in Europe. Currently, a policy for a necessary Public Key Infrastructure to enrol cryptographic keys and certificates for vehicles and infrastructure component is in discussion to enable an interoperable Vehicle-2-Vehicle communication. Vehicle-2-Vehicle communication means that vehicles periodically send Cooperative Awareness Messages. These messages contain the current geographic position, driving direction, speed, acceleration, and the current time of a vehicle. To protect privacy (location privacy, “speed privacy”) of vehicles and drivers ETSI provides a specific pseudonym concept. We show that the Vehicle-2-Vehicle communication can be misused by an attacker to plot a trace of sequent Cooperative Awareness Messages and to link this trace to a specific vehicle. Such a trace is non-disputable due to the cryptographic signing of the messages. So, the periodically sending of Cooperative Awareness Messages causes privacy problems even if the pseudonym concept is applied.
Current global challenges such as climate change, lack of resources, desertification, land degradation as well as loss of biodiversity can ultimately be due to human actions. Reasons are excessive production and consumption of goods and services, along with using and consuming natural resources, causing emissions and waste products. Demand in the form of consumption and supply in the form of production are closely intertwined.
Das Buch beschreibt den seit 2012 bereits eingeleiteten Agenda-2030-Konsultationsprozess, der insbesondere in Europa bis zum Jahr 2020 zu einer Umgestaltung von Wirtschaft und Gesellschaft führen wird. Erstmalig in der Geschichte kommt ab Mitte des Jahres 2016 ein globales Managementsystem zum Einsatz, das zur Fortschrittsüberwachung der 17 Sustainable Development Goals (SDGs) und den 169 globalen Unterzielen weltweit eingesetzt wird. Ein Screening der relevanten politischen Strategien und Beschlüsse verdeutlicht, dass Europa und Deutschland gut auf die Umsetzung der neuen Agenda vorbereitet sind und sich im Zuge der neuen Rechenschaftspflicht zur Umsetzung der SDGs verpflichtet haben. Traditionelle Footprint-Indikatoren, neue Ergänzungsindikatoren sowie standardisierte Richt- und Leitlinien kommen im vorstehenden Zusammenhang zukünftig zum Einsatz. Die zielorientierte globale Steuerung der SDGs fällt in das Aufgabenfeld der Koordinationsfunktion des Life-Cycle-Controllings, das beschrieben wird. Unternehmen tragen maßgeblich zur Umsetzung der SDGs bei und sind daher zunehmend verpflichtet, die negativen Auswirkungen ihres unternehmerischen Handelns transparent zu machen. Dies geschieht mithilfe von Product-Footprints und Footprints für Transportdienstleistungen, die bezüglich ihrer aktuellen und zukünftigen Praxisrelevanz ebenfalls vorgestellt werden. Zahlreiche Praxisbeispiele zeigen zudem, wie Unternehmen schon heute über den Einsatz von SDG- und CSR-Fortschrittsindikatoren ihrer globalen Sorgfaltspflicht in den Lieferantenketten nachkommen.
Traditionally automotive UI focusses on the ergonomic design of controls and the user experience in the car. Bringing networked sensors into the car, connected cars can provide additional information to car drivers and owners, for and beyond the driving task. While there already are technological solutions, such as mobile applications commercially available, research on users’ information demands in such applications is scarce. We conducted four focus groups to uncover what kind of information users might be interested in to see on a second dashboard. Our findings show that besides control screens of todays’ dashboards, people are also interested in connected car services providing context information for a current driving situation and allowing strategic planning of driving safety or supporting car management when not driving. Our use cases inform the design of content for secondary dashboards for and especially beyond the driving context with a user perspective.
The technological development of the digital computer and new options to collect, store and transfer mass data have changed the world in the last 40 years. Moreover, due to the ongoing progress of computer power, the establishment of the Internet as critical infrastructure and the options of ubiquitous sensor systems will have a dramatic impact on economies and societies in the future. We give a brief overview about the technological basics especially with regard to the exponential growth of big data and current turn towards sensor-based data collection. From this stance, we reconsider the various dimensions of personal data and and market mechanisms that have an impact of data usage and protection.
Multiple myeloma is the second most common hematological malignancy. Despite all the progress made in treating multiple myeloma, it still remains an incurable disease. Patients are left with a median survival of 4-5 years. The combined treatment of multiple myeloma with histone deacetylase inhibitors and cytokine-induced killer cells provides a promising targeted treatment option for patients. This study investigated the impact of a combined treatment compared to treatment with histone deacetylase inhibitors. The experiments revealed that a treatment with histone deacetylase (HDAC) inhibitors could reduce cell viability to 59% for KMS 18 cell line and 46% for the U-266 cell line. The combined treatment led to a decrease of cell viability to 33% for KMS 18 and 27% for the U-266 cell line, thus showing a significantly better efficacy than the single treatment.
Vor Gericht werden Einsätze geruchsdifferenzierender Hunde derzeit nur unter bestimmten Voraussetzungen als Indizien-Beweis zugelassen (dokumentierter, ausreichender Ausbildungsstand des Hundes, Bestätigung der Suche durch zweiten Hund). Oft sind Leistungsgrenzen der Hunde hinsichtlich Alter der Geruchsspur, Einfluss bestimmter Witterungsbedingungen (Temperatur, Feuchtigkeit, etc.) auf die Detektierbarkeit menschlicher Geruchsspuren unklar und umstritten. Auch ist bis heute nicht wissenschaftlich untersucht, welche Bestandteile und Einzelsubstanzen des humanen Geruchs für die Hunde tatsächlich wahrnehmbar und wichtig zur Personensuche und -identifikation sind. Daher widmet sich ein aktuelles Promotionsprojekt im Institut für Detektionstechnologien der Erforschung dieser Fragen.
The detection of human skin in images is a very desirable feature for applications such as biometric face recognition, which is becoming more frequently used for, e.g., automated border or access control. However, distinguishing real skin from other materials based on imagery captured in the visual spectrum alone and in spite of varying skin types and lighting conditions can be dicult and unreliable. Therefore, spoofing attacks with facial disguises or masks are still a serious problem for state of the art face recognition algorithms. This dissertation presents a novel approach for reliable skin detection based on spectral remission properties in the short-wave infrared (SWIR) spectrum and proposes a cross-modal method that enhances existing solutions for face verification to ensure the authenticity of a face even in the presence of partial disguises or masks. Furthermore, it presents a reference design and the necessary building blocks for an active multispectral camera system that implements this approach, as well as an in-depth evaluation. The system acquires four-band multispectral images within T = 50ms. Using a machine-learning-based classifier, it achieves unprecedented skin detection accuracy, even in the presence of skin-like materials used for spoofing attacks. Paired with a commercial face recognition software, the system successfully rejected all evaluated attempts to counterfeit a foreign face.
