The origin of oxygen dependence in a potentiometric CO(2) sensor with Li-ion conducting electrolytes
No full textWhen the electrochemical cell arrangement of type III, O(2), CO(2), Au, Li(2)CO(3)\Li(+) conductor\O(2), reference (a(Li2O) = constant) is used to measure the CO(2) concentration in air, the emf should depend only on the logarithmic concentration of CO(2). In reality, however, the sensor response is also affected by the oxygen present in the environment. The oxygen dependence of the CO(2) sensing electrochemical cell originates from an influence of electronic conduction in the electrolyte. The theoretical change of emf with oxygen pressure, which is predicted from the modified emf-equation for the electrochemical cell with a mixed conducting electrolyte, agrees well with the measured emf change.

The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
Tartalomkészítői gyakorlat nyoma a médiaszövegen Li Ziqi videóiban
No full textJelenleg Li Ziqi (magyarul: Li Zicsi) a legnagyobb feliratkozó számmal rendelkező kínai rövidvideó-készítő a YouTube-on, és mint kiemelkedő kínai rövidvideó-készítőnek, az egész világon vannak követői, befolyá sa pedig óriási. Li Ziqi rövid videói az idilli tájat bemutatva egyedi audiovizuális élményt nyújtanak a nézőknek. Úgy gondolom, Li Ziqi követendő példakép, és sikertörténete pozitív tanulságokkal szolgálhat más videobloggerek számára.
A dolgozat első részében az irodalomelemzé si módszerek segítségével és a releváns kínai, magyar és angol nyelvű szakirodalom ö sszefoglalva elemzem az User-Generated Content (UGC) tartalom, a User-Generated Content (PGC) tartalom é s az Occupationally-generated Content (OGC) tartalom jellemzőit és a köztük lévő különbségeket. A rövid videók kínai fejlesztésének 3 szakasza az UGC szakasz, a PGC szakasz és az OGC szakasz, ebben a sorrendben.
A dolgozat második részében Li Ziqi pályafutását három szakaszra osztom a kínai rövidvideó-ipar fejlődésével párhuzamosan: Az egyéni videokészítés szakasza, Teamwork szakasz és a szakmai szervezettel való együttműködés szakasza. A három szakasz mindegyikében Li Ziqi mint tartalomgyártó identitása különböző jellemzőkkel bír. Li Ziqi UGC-tartalomkészítőből PGC-tartalomkészítővé vált egy szakmai csapat létrehozá sával és videói minő ségének javításával, majd OGC-tartalomkészítővé vált egy azonos nevű márka létrehozá sával.
A dolgozat harmadik részében véletlenszerű mintavételi módszert alkalmazva mindegyik szakaszból tíz rövid videót választok ki vizsgálati tárgyként, hogy narratológiai szempontból, konkrétan a narratív alany, a témaválasztás, a narratív tér és a történet cselekménye négy nézőpontból elemezzem Li Ziqi videóinak jellemzőit és változásait az egyes időszakokban.
Kutatásom során megállapítottam, hogy Li Ziqi videóinak szerepstruktúráit az aktantmodell alapján az jellemzi, hogy Li Ziqi egyedüli alanyból főszereplővé válik, akit egyre több mellékszereplő kísér. A videó témája első sorban a hagyományos kínai ételek, kiegészítve a kulturális örökség elemeivel és etnikai kézműves termékekkel. A narratív tér egyszerű és kezdetlegesen felépített helyből gyönyörűen díszített és több helyszínnel rendelkező világgá vált, ahol már a kínai tájak szépségét is – többnyire nagy látószögű felvételeken keresztül – bemutatja. A videó cselekménye viszonylag rögzített, amit ,,küldetés teljesítve”modellnek neveznék. Általánosságban elmondható, hogy Li Ziqi videótartalma és filmkészítési készségei egyre komplexebb termék előállításának irányába haladó tendenciát mutatnak, köszönhetően egy professzionális videógyártó csapat kialakításának, a professzionális MCN (Multi-Channel Network) cégekkel való együttműködésnek és Li Ziqi egyedülálló narratív képességeinek.MSc/MAKommunikáció- és média szakL
Language Change and SA-OT: The case of sentential negation
No full textSimulated Annealing for Optimality Theory (SA-OT) updates Optimality Theory by adding a model of performance to a theory of linguistic competence. Our aim is to show that SA-OT can contribute to language change simulations. Performance "errors" are considered to be one of the causes of variation and change. We have chosen to model the evolution of sentential negation (SN). The descriptive background adopts Jespersen's Cycle, according to which the evolution of sentential negation follows three main stages (1. pre-verbal, 2. discontinuous, and 3. post-verbal). Therefore, we advance a novel model for SN, based on SA-OT. It reproduces the three pure and the two observed mixed stages, whereas it correctly predicts the lack of an intermediate stage between 3 and 1. The success of the approach corroborates the computational, performance-based approach to the data. Finally, we employ the iterated learning paradigm to reproduce historical changes in a "simulated corpus study". This enterprise turns out to be more difficult than one would naively believe.Appeared open access as: Computational Linguistics in the Netherlands Journal (CLIN), vol. 1 (2011), pp. 21-40, and is available at http://www.clinjournal.org/sites/default/files/Lopopolo.pdfA.

The serrated flow behavior of a binary Al-Li alloy tempered to conditions with and without delta precipitates
No full textThe serrated flow behavior of an Al-1.65 wt.% Li alloy in compression was investigated in the present study as a function of temper condition. Same category of serrations were detected for both the delta'-hardened and the delta'-free samples of the alloy. However, it was found that the happening of the serrations is controlled predominantly by the presence and growth of shearable delta', rather than the supersaturation of the matrix. With the presence and growth of delta', the occurrence of serrations is greatly advanced, the serration magnitude is greatly enhanced. Based on a suggestion that the serrations are dynamic strain aging events between lithium atom's and mobile defects for both situations, the positive effect of delta' on serrated flow is rationalized to arise from an enhanced binding energy of lithium atoms to the mobile defects generated with the shearing of ordered delta'.

Theoretical prediction of Li-6/Li-7 separation in solvent extraction system using Urey model
No full textSeparation of lithium isotopes (Li-6, Li-7) is a key technology to the development and utilization of nuclear energy. In this work, we present an efficient method to theoretically estimate the separation factors of Li-6/Li-7 in solvent extraction system based on Urey model. The approach was implemented by calculating the equilibrium separation factor of Li-6/Li-7 in the crown ether/Li aqueous solution [15-crown-5 (15C5), Benzo-15-crown-5 (B15C5), 12-crown-4 (12C4), Dicyclohexyl-18-Crown-6 (DH18C6)/LiX-H2O, X = Cl/I] exchange system utilizing the calculated harmonic vibration frequencies obtained by Density Functional Theory (DFT). The results showed that Urey model can correctly predict the direction of the Li-6/Li-7 separation as observed in the experiments. With this model, the underlying mechanisms driving the equilibrium isotope separation were elucidated further. The coordination structure of the Li complex played a dominant role in the separation of Li-6/Li-7. For the solvent extraction system comprising crown ether phase and LiX aqueous solution, the crown ether with strong ability of excluding the hydrated water of Li gives a higher separation factor. The ways by which Li-O bonding of the Li-crown ether complex can be weakened, such as reducing the coordinated water molecules, applying high polar solvents, performing separation from Li salt with a softer anion, are helpful to improve the separation factor of Li-6/Li-7 at a fixed temperature. The lithium isotopic exchange is an exothermic reaction. Decreasing temperature favors the exchange reaction. This work is expected to provide guidance for the design of the exchanger and screening of the chemical exchange system for the separation of Li-6/Li-7
Potentiometric CO2 gas sensor with lithium phosphorous oxynitride electrolyte
No full textPotentiometric cell, Au/LiCoO2 5 m/o Co3O4/Li2.88PO3.73N0.14/Li2CO3/Au, has been fabricated and investigated for monitoring CO2 gas. A LiCoO2-CO3O4 mixture was used as the solid-state reference electrode instead of a reference gas. The idea is to keep the lithium activity constant on the reference side using thermodynamic equilibrium at a given temperature. The thermodynamic stability of the reference electrode was studied from the phase stability diagram of Li-Co-C-O system. The Gibb's free energy of formation of LiCoO2 Was estimated at 500 degreesC from the measured value of the cell emf. The sensors showed good reversibility and fast response toward changing CO2 concentrations from 200 to 3000 ppm. The emf values were found to follow a logarithmic Nernstian behavior in the 400-500 degreesC temperature range. CH4 gas did not show any interference effect. Humidity and CO gas decreased the emf values of the sensor slightly. NO and NO2 gases affect this sensor significantly at low temperatures. However, increased operating temperature seems to reduce the interference. (C) 2001 Elsevier Science B.V.
