Online Dating Profile Analysis: The Intersection of Identity, Gender & Religion

According to standpoint theory, individuals experience the world based on the social groups that they belong to. Using this theoretical lens, my content analysis compared how gender and religion were conveyed on the user profiles of three online dating sites: JDate.com, ChristianMingle.com and OkCupid.com. In my initial reading of data, I used inductive thematic analysis to distinguish 7 categories of words and 7 categories of photographs that were relevant to portrayals of gender and religion. These categories were then analyzed through frequency counts by adding the total number of word types and photograph types used by men and women on each site. Findings showed an emphasis on religious cultural background on ChristianMingle.com. Gender roles were supported overall with male emphasis on career and sports and female emphasis on attractiveness and care

Model Predictive Control Based Trajectory Generation for Autonomous Vehicles - An Architectural Approach

Research in the field of automated driving has created promising results in the last years. Some research groups have shown perception systems which are able to capture even complicated urban scenarios in great detail. Yet, what is often missing are general-purpose path- or trajectory planners which are not designed for a specific purpose. In this paper we look at path- and trajectory planning from an architectural point of view and show how model predictive frameworks can contribute to generalized path- and trajectory generation approaches for generating safe trajectories even in cases of system failures.Comment: Presented at IEEE Intelligent Vehicles Symposium 2017, Los Angeles, CA, US

Herbage Characteristics Affecting Intake by Dairy Heifers Grazing Grass-Monoculture and Grass-Birdsfoot Trefoil Pastures

Pasture-based dairies have become more prevalent in recent years due to a higher proportion of organic milk demand and production. Organic certification requires that animals must graze at least 120 days in each growing season. However, dry matter intake is often limited when dairy animals receive most of their herbage from pasture, resulting in lower animal performance and milk production. The purpose of this study was to analyze the complimentary effect of high energy grasses with birdsfoot trefoil (BFT) tannins to improve intake of dairy heifers. Jersey heifers were rotationally grazed for 105 days in 2017 and 2018 on eight different pasture treatments, which included monocultures of perennial ryegrass (PR), orchardgrass (OG), meadow bromegrass (MB), and tall fescue (TF), with each respective grass also planted in mixture with BFT. Intake was measured by sampling herbage before and after each seven-day grazing period and was from greatest to least as follows: MB+BFT, OG+BFT, OG, MB, PR+BFT, TF+BFT, PR, TF. Physical characteristics such as pasture bulk density, herbage height, herbage allowance, leaf pubescence, leaf softness, and birdsfoot trefoil content as well as nutritional properties such as fat, non-fibrous carbohydrates, fiber, and energy were all associated with intake. Crude protein and ash were also associated with intake. While PR+BFT did not have the greatest overall intake, it was the only treatment that consistently had greater intake than its respective grass monoculture (PR). Since it had more energy and tannins than all other grasses, a complimentary effect between energy and tannins to increase intake was likely. The fact that both physical and chemical herbage characteristics were associated with intake shows the importance of planting the right species in pasture as well as making proper management decisions to maximize nutritive value and herbage intake

A novel method for motion artifact removal in wearable ppg sensors based on blind source separation

Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG geförderten) Allianz- bzw. Nationallizenz frei zugänglich.This publication is with permission of the rights owner freely accessible due to an Alliance licence and a national licence (funded by the DFG, German Research Foundation) respectively.The recent development of healthcare systems has provided a significant contribution to ambulatory patient monitoring. In that context, signal quality and disturbances induced by noise or motion artifacts play an important role in the field of signal processing tasks. Especially the Photoplethysmogram (PPG) is very liable to movement artifacts which severely hamper the extraction of vital parameters like the heart rate or oxygen saturation. To record patient movements, an innovative sensor system is proposed, which acquires accelerometer data next to the PPG. As in Adaptive Noise Cancelers, we propose to use the acceleration as reference to recover corrupted PPGs by means of the Blind Source Separation. Sophisticated methods of ICA have been used, resulting in a novel approach for artifact suppression in the PPG that has been tested on laboratory datasets

Neuartige, hochporöse organische Gerüstverbindungen sowie Fasermaterialien für Anwendungen in adsorptiven Prozessen und Katalyse

Poröse Materialien sind für eine Vielzahl industrieller, aber auch alltäglicher Prozesse essentiell und daraus nicht mehr wegzudenken. So erstrecken sich die Anwendungen von einfachen, auf Aktivkohle basierenden Wasserfiltern in Heimaquarien, über Zeolithe in selbstkühlenden Bierfässern bis hin zu weltweit genutzten, großtechnischen Verfahren in der Abtrennung von Schadstoffen aus Luft und Wasser. Außerdem werden poröse Materialien als Katalysatoren in Prozessen eingesetzt, die eine Grundlage der Konsumgüterproduktion der heutigen Gesellschaft bilden. In den letzten Jahrzehnten wurde eine Vielzahl neuer hochporöser Verbindungen entwickelt, wobei besonders in den letzten Jahren polymerbasierten Adsorbentien ein gesteigertes Interesse galt. Diese organischen Gerüstverbindungen zeichnen sich durch eine große strukturelle und funktionelle Vielfalt aus, die auf den modularen Aufbau aus multifunktionellen organischen Einheiten (Linker) und verknüpfenden Gruppen (Knoten, Konnektoren) zurückzuführen ist. Neben ihrer homogenen Oberflächenchemie weisen diese Materialien signifikant hydrophobere Oberflächen als herkömmliche Adsorbentien, wie z.B. Aktivkohlen, auf. Dadurch sind die organischen Gerüstverbindungen bestens geeignet, um unpolare organische Komponenten aufgrund attraktiver Wechselwirkung adsorptiv zu binden. Entsprechende Verfahren gewinnen immer stärker an Bedeutung, um z.B. hochtoxische flüchtige organische Verbindungen (VOCs – volatile organic compounds) aus Luft und Wasser durch entsprechende Filter zu entfernen. Im Rahmen dieser Arbeit wurden verschiedene Ansätze verfolgt, um neuartige organische Gerüstverbindungen herzustellen, die sich durch o.g. unpolare innere Oberflächen auszeichnen (Abbildung 1). Dazu fanden verschiedene synthetische Konzepte Anwendung. Zum einen wurden multifunktionelle organische Linker durch Lithiierung zu starken Nukleophilen umgesetzt, die anschließend über alkylsubstituierte Konnektoren auf Silanbasis vernetzt werden konnten. Durch diese aliphatische Funktionalisierung der Materialien EOF-10 bis -14 (EOF – element organic framework) konnte die Oberflächenpolarität gegenüber vergleichbaren Gerüstverbindungen signifikant gesenkt werden, was wiederum die Wechselwirkungen mit unpolaren Substanzen erhöht. Weiterhin stand die Herstellung und Charakterisierung poröser Polymere über die palladiumkatalysierte Suzuki-Kupplung im Vordergrund, bei der die Linker über die C-C-Verknüpfungsreaktion direkt gebildet und dadurch polare Gruppen an den Konnektoren vermieden werden konnten (EOF-6 bis -9). Diese Verbindungen erreichen spezifische Oberflächen von bis zu 1380 m2g-1 und adsorbieren signifikant größere Mengen des unpolaren Gases n-Butan als weniger polare Aktivkohlen mit vergleichbar großer Oberfläche. Ein dritter Ansatz zur Synthese unpolarer Adsorbentien war die Herstellung von Polyphenylenen über die Cyclotrimerisierung multifunktioneller Acetylverbindungen. Die resultierenden porösen, stark unpolaren Polymere OFC-1 bis -4 (OFC – organic framework by cyclotrimerization), die jeweils über zwei verschiedene Syntheserouten in Lösung bzw. in einer lösungsmittelfreien Schmelze hergestellt werden konnten, wurden durch postsynthetische Funktionalisierung anwendungsspezifisch modifiziert. Außerdem wurden verschiedene Verarbeitungsmöglichkeiten zu monolithischen und textilen Adsorbern über die Syntheseroute aus der Schmelze untersucht. Neben der Herstellung hydrophober Adsorbentien ermöglicht der modulare Aufbau organischer Gerüstverbindungen die Immobilisierung katalytisch aktiver molekularer Spezies. Über die zwei erstgenannten Syntheserouten konnten poröse Netzwerke hergestellt werden, die großes Potential für Anwendungen als heterogene Katalysatoren in bisher überwiegend homogen geführten Prozessen aufweisen (Abbildung 1). So wurde ein hochvernetztes, poröses zinnorganisches Polymer (EOF-3) synthetisiert, dessen katalytische Aktivität in der Cyanosilylierung von Benzaldehyd gezeigt wurde. Dieses Material ist besonders für Ver- und Umesterungsreaktionen in der Oleochemie von Interesse, da derartige Reaktionen überwiegend homogen katalysiert werden. Des Weiteren ermöglichte die Suzuki-Kupplung als Verknüpfungsreaktion den Einbau eines bifunktionellen Imidazoliumlinkers in offenporige, hochvernetzte Polymere (EOF-15/-16). Durch Deprotonierung der Imidazoliumeinheiten wurden N-heterocyclische Carbene (NHC) erzeugt, deren katalytische Aktivität in der Organokatalyse in Kombination mit einer heterogenen Reaktionsführung gezeigt werden konnte. Neben der Entwicklung neuartiger organischer Gerüstverbindungen für Anwendungen als hydrophobe Adsorber und heterogene Katalysatoren behandelte die Dissertation die Verarbeitung poröser Materialien (Abbildung 1). Diese fallen in den meisten Fällen in Form feiner Pulver an, was in Abhängigkeit des Anwendungsgebietes zu Problemen führen kann. Speziell für Filteranwendungen ist eine gute Zugänglichkeit des Porensystems durch eine feine Verteilung der adsorptiven Komponente notwendig. Dafür eignen sich Kompositmaterialien aus porösen Pulvern und Fasern. Eine Alternative stellt die Herstellung von Fasermaterialien mit intrinsischer Porosität dar. Beide Ansätze wurden im Rahmen dieser Arbeit aufgegriffen. Über die Methode des elektrostatischen Spinnens können Vliese extrem feiner Fasern nahezu aller Polymere hergestellt werden. Auch die Produktion von Kompositfasern ist bekannt. Bislang gibt es allerdings sehr wenige Arbeiten zur Herstellung poröser Fasermaterialien über diese Methode. Die Verarbeitung metallorganischer Gerüstverbindungen als Modellsubstanzen über Elektrospinnen zu porösen Kompositfasern wurde untersucht. Es konnten Beladungen von bis zu 80 Gew.-% der porösen Materialien in den Kompositfasern erreicht werden, ohne dass die Porensysteme durch den polymeren Binder blockiert wurden. Weiterhin erfolgte die Verarbeitung von Polycarbosilan, einem polymeren Precursor für keramische Materialien, über Elektrospinnen zu feinen Fasern. Diese wurden durch Pyrolyse zu SiC-Fasern und durch anschließende extraktive Entfernung der Siliziumatome durch Chlorierung zu porösen CDC-Fasern (CDC – carbide-derived carbon) mit außerordentlichen Adsorptionseigenschaften umgesetzt

Water at an electrochemical interface - a simulation study

The results of molecular dynamics simulations of the properties of water in an aqueous ionic solution close to an interface with a model metallic electrode are described. In the simulations the electrode behaves as an ideally polarizable hydrophilic metal, supporting image charge interactions with charged species, and it is maintained at a constant electrical potential with respect to the solution so that the model is a textbook representation of an electrochemical interface through which no current is passing. We show how water is strongly attracted to and ordered at the electrode surface. This ordering is different to the structure that might be imagined from continuum models of electrode interfaces. Further, this ordering significantly affects the probability of ions reaching the surface. We describe the concomitant motion and configurations of the water and ions as functions of the electrode potential, and we analyze the length scales over which ionic atmospheres fluctuate. The statistics of these fluctuations depend upon surface structure and ionic strength. The fluctuations are large, sufficiently so that the mean ionic atmosphere is a poor descriptor of the aqueous environment near a metal surface. The importance of this finding for a description of electrochemical reactions is examined by calculating, directly from the simulation, Marcus free energy profiles for transfer of charge between the electrode and a redox species in the solution and comparing the results with the predictions of continuum theories. Significant departures from the electrochemical textbook descriptions of the phenomenon are found and their physical origins are characterized from the atomistic perspective of the simulations.Comment: 29 pages, 15 figure

Australia and Canada in Regional Fisheries Organizations: Implementing the United Nations Fish Stocks Agreement

In the late 1980s and early 1990s a number of factors and events coalesced to encourage the international community to re-examine high seas fisheries issues. The need to enhance the effectiveness of regional fisheries organizations led to the development of the 1995 United Nations Fish Stocks Agreement, dealing with straddling and highly migratory stocks. Both Canada and Australia played a significant role in the development of this agreement While having much in common, each state had different interests and concerns Canada\u27s attention was focused on the problem of straddling stocks, while Australia \u27s interests have been primarily, though not exclusively, directed at highly migratory species. This paper analyses Australian and Canadian practices in relation to regional fishenes organizations, with a particular emphasis on the United Nations Fish Stocks Agreement

Appropriation of the Highest Order: A Study of Harry Smith’s Master Work, Film No. 18 Mahagonny in relation to the Brecht-Weill opera The Rise and Fall of the City of Mahagonny and Duchamp’s The Large Glass

Harry Smith’s Film No. 18, Mahagonny, 1970 – 1980, is a transmutation of the original Brecht-Weill opera, The Rise and Fall of the City of Mahagonny, a 1930, into a feature-length experimental film. This paper shows how the original opera and Duchamp\u27s The Large Glass prove inherent to Smith’s double-pronged homage to both original works of art. The failure in the opera narrative and the chance shattering of The Large Glass inform Smith’s complex methodology to approach and spatialize cinema. Harry Smith’s use of the tools of the screening apparatus are traced in order to study Mahagonny in detail. The film exemplifies his practice of making works of art that extend outside their parameters, in this case, the screen. Through this analysis of Mahagonny, the specific differences between film, artifact, stage, appropriation, and art object fall apart

Selective catalytic synthesis of short chain oxymethylene ethers by a heteropoly acid – a reaction parameter and kinetic study

Oxymethylene ethers (OME) are considered as a low-emission additive or replacement to diesel fuel. They can be synthesized by different routes based on C₁ platform chemicals in different oxidation states. The challenge is to tune the acidic catalyst for the condensation reaction to a selectivity for a certain oligomeric fraction (OME₃₋₅) for optimal fuel properties. Herein, we report the use of heteropoly acids that showed an outstanding activity and selectivity for the production of the respective OME fraction under very mild reaction conditions. Trioxane and dimethoxymethane (OME₁) were used as substrates which are both products of the methanol value-added chain. Reaction parameters such as catalyst/substrate ratio and temperature could be reduced considerably due to a high catalytic activity and selectivity. Kinetic data were obtained experimentally and modelled to estimate the reaction rate, activation energy and pre-exponential factor as a solid basis for further reaction engineering
