Satzadverbien - korpusbasiert

German research literature shows a great lack of empirical studies of sentence adverbs. Indications about their significance and linguistic application in dictionaries are sometimes inappropriate or even misleading. Apart from that, there is little corpus linguistic research about synsemantica in the German language. Initially, however, we have to question whether words that are poor in content such as sentence adverbs can actually be empirically studied with the support of a corpus, for instance the Deutsches Referenzkorpus. In our opinion, they undoubtedly can. The following essay will demonstrate where corpus based linguistic research can lead. Step by step, the methodical approach, being at the basis of the research of sentence adverbs in modern German, will be illustrated in the discussion (chapter 2). The two examples glücklicherweise and paradoxerweise will furthermore exemplify the applied methods (chapter 3). Finally, the comparison of newly acquired results with entries in dictionaries clearly proves the great value of such research in the fields of lexicography and German as a foreign language (chapter 4)

Modeling the Behavior of the Surface to Liquid Interfaces in an Electrolytic Liquid

Understanding the mechanism for charge transfer between electrodes within an electrolyte dissolved in water is vital to better understanding the sources of electrical noise in the system. This research compares the electrical properties of liquid top gated graphene devices with the properties of two metal probes to model the system. By measuring the impedance of these systems at different frequencies, it is possible to develop a model of their electrical properties and to consider techniques to improve signal to noise at graphene interfaces

The effects of manufacturing variability on turbine vane performance

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Aeronautics and Astronautics, 2008.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (leaves 71-73).Gas turbine vanes have airfoil shapes optimized to deliver specific flow conditions to turbine rotors. The limitations of the manufacturing process with regards to accuracy and precision mean that no vane will exactly match the design intent. This research effort is an investigation of the effects of manufacturing-induced geometry variability on the performance of a transonic turbine vane. Variability is characterized by performing Principal Components Analysis (PCA) on a set of measured vanes and then applied to a different vane design. The performance scatter of that design is estimated through Monte Carlo analysis. The effect of a single PCA mode on performance is estimated and it is found that some modes with lower geometric variability can have greater impact on performance metrics. Linear sensitivity analysis, both viscous and inviscid, is carried out to survey performance sensitivity to localized surface perturbations, and tolerances are evaluated using these results. The flow field is seen to be practically insensitive to shape changes upstream of the throat. Especially sensitive locations like the throat and trailing edge are investigated further through nonlinear sensitivity analysis.by John D. Duffner.S.M

Europäisch eingestellt – Valenzforschung mit Parallelkorpora

The aim of this research is to demonstrate with a case study the significance of corpus linguistics within the field of verb valency and bilingual lexicography. Specifically, we will introduce a corpus-based process that determines context-sensitive translations of polysemous word forms. Three steps are considered here in detail. First, text evidences of the verb einstellen in the monolingual Deutsches Referenzkorpus (DeReKo) will be examined with a collocation analysis. With help of the analytical instrument COSMAS II, the collocation profiles will then be summarized into a typology (senses and subsenses, valency structures and typical collocations). In a further step, the determined senses can be attributed to the corresponding translations of the word form einstellen in other languages (English, French and Italian) by means of the multilingual parallel corpus Europarl (Open Source Parallel Corpus OPUS). Finally, the results will be compared to the codifications of commonly used bilingual dictionaries

Passive dispersal of the grape rust mite Calepitrimerus vitis Nalepa 1905 (Acari, Eriophyoidea) in vineyards

Modes of passive dispersal of the grape rust mite Calepitrimerus vitis (Eriophyoidea) were investigated in a vineyard of South-Western Germany. More than 200 Eriophyoidea per month were trapped in a wind chamber during summer (32,1 % C. vitis) suggesting long-distance dispersal by air currents. Rain washed part of the adult C. vitis population from the foliage. SE micrographs suggest that quiescent nymphs are affixed to the leaf by a substance of unknown nature. However, the role of rain in C. vitis colonisation of uninfested vineyards is still unclear, as is the role of phoretic transport by arthropods. For the first time, evidence of rust mite dispersal by human activity is presented. A large number of C. vitis was found adhering to clothes and hands of workers carrying out customary cultural practices in the vineyard. Other arthropods, including Typhlodromus pyri, the main predator of C. vitis, were also passively transported by wind, rain and human activit

MPEG-1 bitstreams processing for audio content analysis

In this paper, we present the MPEG-1 Audio bitstreams processing work which our research group is involved in. This work is primarily based on the processing of the encoded bitstream, and the extraction of useful audio features for the purposes of analysis and browsing. In order to prepare for the discussion of these features, the MPEG-1 audio bitstream format is first described. The Application Interface Protocol (API) which we have been developing in C++ is then introduced, before completing the paper with a discussion on audio feature extraction

Digitale Textdatenbanken im Vergleich

The present paper offers a comparative presentation of the possibilities and limits of five of the most important large digital corpora on present day German which are currently publicly available (Leipzig, DWDS, COSMAS, COSMAS tagged and TIGER). The aim of this article is to put at the researcher's disposal a comprehensive survey of the possibilities for using automatic search devices in the fields of lexicology, morphology, word formation and syntax. Special attention is given to the comparison of the performance and user friendliness of the proposed search options and analysis tools (lemmatisation, cooccurrence analysis, etc.). The information given in this paper is condensed in several comparative synopses which are individually understandable to a reader who does not want to have recourse to the full text

Human Factors Analysis of Predator B Crash

The 2006 crash of a Predator B in Arizona has prompted a great amount of scrutiny into Unmanned Arial System (UAS) operations. The direct cause of the Predator crash can be tied to an initial failure of the displays and a failed transfer of controls between operators. However, using the Human Factors Analysis and Classification System (HFACS), many latent errors that contributed to the accident were uncovered that were not addressed by the National Transportation Safety Board (NTSB) report. The HFACS approach for this accident examined all issues leading up to the crash and uncovered several organizational influences that were significant contributors to the Predator crash. Through augmenting NTSB efforts with the HFACS method, future UAS incidents can be prevented by addressing all causes, regardless of their distance from the pilot’s seat
