Evaporative drying of cupric-chloride droplets in a thermo-chemical cycle of hydrogen production

Slowikowski, Mateusz 01 August 2012 (has links)
In this thesis, new empirical correlations that predict the behaviour of Cupric-Chloride droplets undergoing spraying and drying processes are developed. Cupric-Chloride is a chemical compound with the formula CuCl2 that is present as slurry or aqueous solution within the Copper-Chlorine (Cu-Cl) thermo-chemical cycle for generation of hydrogen. An experimental study examines the effects of inlet air and liquid temperatures, pressure, concentration, nozzle diameter, and liquid flow rate on the outlet air temperature, particle size, particle size distribution, morphology, moisture content, bulk density, and flowability. The analysis examines a single droplet of CuCl2 solution in a continuum drying media. The validation of the model involves comparisons with experimental data from previous studies of different fluids based on non-dimensional analysis. The study provides new information about the effects of different concentrations of water in the CuCl2 slurry drying at low to moderate air temperatures.Analytical correlations of heat and mass transfer are developed for the aqueous solution, subject to various drying conditions. The analysis is performed for moist air in contact with a sprayed aqueous solution of Copper (II) Chloride Dihydrate [CuCl2 ·(2H2O)]. Validation of the model is performed by comparisons with experimental results. / UOIT

Korean evidentials in discourse

Kim, Jinung 12 July 2012 (has links)
The purpose of this dissertation is a study of Korean evidentiality on the basis of presuppositional analysis. My claim is that Korean evidentiality can be accounted for under the binding theory of presupposition (Asher & Lascarides 1998; 2003; Asher 2000). The proposal I motivate in this dissertation is that interpretations of Korean evidentials can be handled using the same mechanism which resolves anaphoric expressions.Dynamic Semantics such as DRT and SDRT give a contribution to account for phenomena like anaphora bridging, presupposition, and accomodation bythe update procedure of the discourse structure. I investigate Korean evidentials by examining their distributions and functions in Korean grammar and specifying the types of information source in Korean evidential system. In particular,there are three evidential types in Korean: Direct te, Reportative tay, Inference ci. I propose that the Korean evidential system corresponds to B-1 system in Aikhenvald (2004). I also give an analysis of the intonation phrase of utterances featuring Korean evidentials with the autosegmental-metrical model of intonational phonology. Moreover, I argue that Korean evidentials are presupposition triggers. To verify my claim, I provide various tests such as negation, challengeability and the interrogative flip. All the tests support for classifying Korean evidentials as one category. I also review and compare three different theoretical frameworks: modal, illocutionary and presuppositional analysis. I reject a modal analysis and an illocutionary analysis and employ a presuppositional analysis for Korean evidentiality.I propose that Korean evidentiality can be explained in terms of SDRT(Asher & Lascarides 1998; 2003). Asher & Lascarides (1998) regard presupposition resolution as an integrated part of the task of building discourse relations. I also show that the speaker-dependency of evidentiality is explicitly associated with characteristics of indexicals. Just as in the line of work stemming from Hunter & Asher (2005), I demonstrated that Korean evidentials are anaphorically resolved by the extra-linguistic context as well as by the linguistic context. / text

According to the National Cancer Institute (INCA) in 2014 were diagnosed 52,680 new cases in Brazil, a number that corresponds to a 22% increase over the year 2013. Being responsible for approximately 39% of women's deaths cancer patients. Despite the high incidence rate, mortality from this cancer has declined since the late eighties, thanks to advances in research on methods for early diagnosis. However, correctly diagnosing cancer is a complex and difficult process as a result of the different variables involved. For an accurate diagnosis, a lot of experience and especially it is required, that the classification of clinical staging of tumor (cancer stage) is correct. The conditions used traditional classification systems are complex and often offer limitations. As is the case of mammography technique, widely used, it is not as effective for women with dense breasts, surgically altered, or under 40 years. Thus, it becomes necessary to develop integrated systems that combined with the professionals in the field experience, allows performing accurate diagnosis in detecting breast cancer. The objective of this study is to apply the technique SVM (Support Vector Machine), so as to assist in the diagnostic interpretation of microcalcifications detected on screening mammography. The data set used consisted of 961 samples of mammograms, obtained from the Radiology Institute of the University of Erlangen Nuremberg. In this set we have information on the age of the patient, BI-RADS (Breast Imaging Reporting and Data System), shape, mass, density and severity (benign | malignant) of microcalcifications. The SVM was developed implemented using the R software (R Development Core Team; http: // www.R-project.org/). The data were divided into two groups: the training set consisting of 80% of the samples of mammographic, used to estimate the model parameters and the independent test set, with 20% of the remaining samples, used to measure the performance of SVM . To evaluate the performance of proposed computational model we used the value of the Total Precision or Accuracy (ACC), sensitivity (S) and specificity (E). The results presented by SVM in identifying malignant lesions in patients with calcifications remained between 72.7% and 100%, which shows that they achieved a satisfactory level in relation to other literatures applied / O c?ncer de mama ? a segunda neoplasia mais frequente no mundo. Segundo dados do Instituto Nacional de C?ncer (INCA), no ano de 2014 foram diagnosticados 52.680 novos casos no Brasil, n?mero este que corresponde a um aumento de 22% em rela??o ao ano de 2013. Sendo respons?vel por aproximadamente 39% dos ?bitos das mulheres portadores de c?ncer. Apesar da elevada taxa de incid?ncia, a mortalidade causada por esta neoplasia tem diminu?do desde o final dos anos oitenta, gra?as ao avan?o das pesquisas em m?todos para o diagn?stico precoce. No entanto, diagnosticar corretamente o c?ncer ? um processo complexo e muito dif?cil em consequ?ncia das diversas vari?veis envolvidas. Para um diagn?stico preciso, exige-se muita experi?ncia e, principalmente, que a classifica??o do estadiamento cl?nico do tumor (est?gio do c?ncer) esteja correta. Os tradicionais sistemas de classifica??o de patologias utilizados s?o complexos e em muitas vezes oferecem limita??es. Como ? o caso da t?cnica de mamografia, que amplamente utilizada, n?o ? t?o eficaz para mulheres com mamas densas, cirurgicamente alteradas ou com menos de 40 anos. Desta forma, torna-se necess?rio o desenvolvimento de sistemas integrados que combinados com a experi?ncia dos profissionais da ?rea, possibilite realizar o diagn?stico preciso na detec??o do c?ncer de mama. O objetivo do presente trabalho ? aplicar a t?cnica SVM (M?quina de Vetor de Suporte), de sorte a auxiliar na interpreta??o diagn?stica das microcalcifica??es detectadas em mamografia de rastreamento. O conjunto de dados utilizado consistiu de 961 amostras de exames mamogr?ficos, obtidos junto ao Instituto de Radiologia da Universidade de Erlangen- Nuremberg. Neste conjunto possu?mos informa??es referentes a idade da paciente, classifica??o BI-RADS ( Breast Imaging Reporting and Data System), forma, massa, densidade e severidade (benigno|maligno) das microcalcifica??o. A SVM desenvolvida foi implementada utilizando-se o software R (R Development Core Team; http:// www.R-project.org/ ) . Os dados foram divididos em dois grupos: o conjunto de treinamento composto por 80% das amostras de exames mamogr?ficos, usado para estimar os par?metros do modelo e o conjunto de teste independente, com 20% das amostras restantes, utilizado para mensurar a performance da SVM. Para avaliar o desempenho do modelo computacional proposto foram utilizados o valor da Precis?o Total ou Acur?cia (ACC), Sensibilidade (S) e Especificidade(E). Os resultados apresentados pela SVM na identifica??o das les?es malignas em pacientes portadores de microcalcifica??es se mantiveram entre 72,7% e 100% o que demonstram que os mesmos alcan?aram um grau satisfat?rio em rela??o com outras literaturas aplicadas

Ádám's Conjecture and Its Generalizations

Dobson, Edward T. (Edward Tauscher) 08 1900 (has links)
This paper examines idam's conjuecture and some of its generalizations. In terms of Adam's conjecture, we prove Alspach and Parson's results f or Zpq and ZP2. More generally, we prove Babai's characterization of the CI-property, Palfy's characterization of CI-groups, and Brand's result for Zpr for polynomial isomorphism's. We also prove for the first time a characterization of the CI-property for 1 SG, and prove that Zn is a CI-Pn-group where Pn is the group of permutation polynomials on Z,, and n is square free.
