Integrating Massive Data Streams
No full textData Integration has been a long-standing and challenging problem for enterprises and researchers. Data residing in multiple heterogeneous sources must be integrated and prepared such that the valuable information that it carries, can be extracted and analysed. However, the volume and the velocity of the produced data in addition to the modern business needs for real-time results have pushed data analytics, and therefore data integration, towards data streams. While data integration is a hard problem in and of itself, integrating data streams becomes even more challenging. Streams are characterized by their high velocity, infinite nature and predisposition to concept drift.The goal of this doctoral work is to design and provide scalable methods to support data integration tasks on massive data streams, i.e., support streaming data integration. The aim of this work is threefold. First, we aim at developing and proposing streaming methods to compute temporal stream data-profiles and summaries that can describe the dynamic state of a stream in the course of time. Second, we aim at developing methods and metrics of stream similarity. Those methods and metrics can serve as means to detect similar or complementary streams in a streaming data lake. Finally, we aim at optimizing distributed streaming similarity joins - a very important operation that precedes entity linking and resolution. This paper discusses exciting challenges and open problems in the field, and a research plan on tackling them.Web Information SystemsSoftware Technolog
The 2015 Illapel earthquake, central Chile: A type case for a characteristic earthquake?
No full textOn 16 September 2015, the M-W = 8.2 Illapel megathrust earthquake ruptured the Central Chilean margin. Combining inversions of displacement measurements and seismic waveforms with high frequency (HF) teleseismic backprojection, we derive a comprehensive description of the rupture, which also predicts deep ocean tsunami wave heights. We further determine moment tensors and obtain accurate depth estimates for the aftershock sequence. The earthquake nucleated near the coast but then propagated to the north and updip, attaining a peak slip of 5-6 m. In contrast, HF seismic radiation is mostly emitted downdip of the region of intense slip and arrests earlier than the long period rupture, indicating smooth slip along the shallow plate interface in the final phase. A superficially similar earthquake in 1943 with a similar aftershock zone had a much shorter source time function, which matches the duration of HF seismic radiation in the recent event, indicating that the 1943 event lacked the shallow slip.SCI(E)[email protected]
Appetitive and aversive visual learning in freely moving Drosophila
No full textTo compare appetitive and aversive visual memories of the fruit fly Drosophila melanogaster, we developed a new paradigm for classical conditioning. Adult flies are trained en masse to differentially associate one of two visual conditioned stimuli (blue and green light as conditioned stimuli or CS) with an appetitive or aversive chemical substance (unconditioned stimulus or US). In a test phase, flies are given a choice between the paired and the unpaired visual stimuli. Associative memory is measured based on altered visual preference in the test. If a group of flies has, for example, received a sugar reward with green light, they show a significantly higher preference for the green stimulus during the test than another group of flies having received the same reward with blue light. We demonstrate critical parameters for the formation of visual appetitive memory, such as training repetition, order of reinforcement, starvation, and individual conditioning. Furthermore, we show that formic acid can act as an aversive chemical reinforcer, yielding weak, yet significant, aversive memory. These results provide a basis for future investigations into the cellular and molecular mechanisms underlying visual memory and perception in Drosophila
The model law on intellectual property : the results of the GR UR research project
No full textThe article presents the draft proposal for the comprehensive reform of the German law of intellectual property. The draft Code of Intellectual Property is a model law consisting of ten books that aims at an overall codification at a national level. The project, which was sponsored by the Deutsche Vereinigung für Gewerblichen Rechtsschutz und Urheberrecht (GR UR), is an attempt to modernize the regulatory technique by furnishing general rules on both substantive and procedural issues, that are merged together with the rules on the specific intellectual property rights into a comprehensive code of intellectual property. The author provides for an introduction to the underlying goals of the project and for a brief description of the comprehensive general part contained in Book 1, procedural rules containedin Book 2, and the rules of the existing statutory provisions contained in Books 3-9. Finally, the author discusses the Books 10A and 10 B that contain description and proposals for possible further development of the German Act on Employees' Inventions towards an employees' creations law covering all types of protected achievements
Metadiégesis y pseudodiégesis en la narrativa de Juan Valera
No full textMetadiegesis and pseudodiegesis in the œuvre of Juan Valera
The narrators in Valera generally appear as representations of their author's voice. Valera uses textual doubles to frame the story by reflecting on it and identifying its (ficticious) source, usually either a manuscript or an informant's account. While in either case the identification of the source leads the reader to expect the narrative presentation of the story proper to be delegated from the extradiegetic level to the diegetic level, in most of his texts Valera does not follow this obvious path. Rather, his homo-extradiegetic narrators tend to appropriate the narrating voice of the original source, taking over the narration on their own behalf. From a narratological perspective, on erasing the textual marks that allow readers to distinguish between different levels of narration, Valera infringes the narrative hierarchy, thereby producing instances of what has been termed pseudodiegesis.
Altenberg shows that the narrative frames in Valera's œuvre, with their numerous reflections and refractions, not only raise a number of poetological issues but, more importantly, function as metafictional mises en abyme, whose performative dimension consists in illustrating the attitude that, according to the author, underlies the poetic-narrative appropriation of reality. It becomes clear that verisimilitude and coherence are the key concepts that, in Valera's view, set fiction apart from history. While the explicit confrontation of the 'historical method' and the 'novelistic method', with a clear preference for the latter, appears at a relatively late stage of Valera's writing, the dissociation of the narrator from the source of information as well as the poetological attitude behind it are characteristic of his narrative from the beginning. In conclusion, far from being an end in itself, the pseudodiegetic trangression is a textual representation of a particular way of appropriating reality that is essential to Valera's narrative poetics
Improving the Sensory Capabilities of an Electromagnetic Guided Rotary Table for the Use in Machine Tools
No full textAbstractDifficult-to-machine materials are still challenging the production industry. Examples are highly complex components of aircraft engines. Alongside innovative processes, also improved machine tool components are helping to comply with the demands of this task.This paper presents a swivel rotary table with an active magnetic bearing (AMB). Opportunities in machining through employing a workpiece-sided AMB are presented. The inherent capabilities to work as a sensor and actor as well as its stiffness and damping depend on the precise knowledge of the magnets characteristics. Therefore, a methodology to automatically identify the characteristic curve is presented
Author and Narrator: Problems in the Constitution and Interpretation of Fictional Narrative
No full textThe eccentricity effect of inhibition of return is resistant to practice
No full textInhibition of return (IOR) refers to a delayed responding to targets appeared at previously cued location relative to an uncued novel location. In a recent study, Bao and Poppet I 1 I reported a functional dissociation of inhibitory processing in the visual field with much stronger IOR magnitude in the far periphery relative to the perifoveal visual field up to 15 degrees eccentricity. The present study aimed to examine whether this effect is sensitive to participant experience or practice. Consistent with previous findings, our data demonstrated a larger IOR magnitude at 21 degrees relative to 7 degrees stimulus eccentricity. More importantly, no practice-related IOR magnitude changes were observed for both perifoveal and peripheral stimuli, although response times did decrease significantly with practice. These results suggest that the eccentricity effect of IOR is a robust phenomenon which is resistant to practice. (C) 2011 Elsevier Ireland Ltd. All rights reserved
