The effect of distribution of information on recovery of propagating signals

THE EFFECT OF DISTRIBUTION OF INFORMATION ON RECOVERY OF PROPAGATING SIGNALS Özgecan Karabulut Ms. in Electrical and Electronics Engineering Advisor: Prof. Dr. Haldun M. Özaktaş September, 2015 Interpolation is one of the fundamental concepts in signal processing. The analysis of the difficulty of interpolation of propagating waves is the subject of this thesis. It is known that the information contained in a propagating wave field can be fully described by its uniform samples taken on a planar surface transversal to the propagation direction, so the field can be found anywhere in space by using the wave propagation equations. However in some cases, the sample locations may be irregular and/or nonuniform. We are concerned with interpolation from such samples. To be able to reduce the problem to a pure mathematical form, the fractional Fourier transform is used thanks to the direct analogy between wave propagation and fractional Fourier transformation. The linear relationship between each sample and the unknown field distribution is established this way. These relationships, which constitute a signal recovery problem based on multiple partial fractional Fourier transform information, are analyzed. Recoverability of the field is examined by comparing the condition numbers of the constructed matrices corresponding to different distributions of the available samples.
Reducing Emissions from Nepal’s Community Managed Forests: Discussion for CoP 14 in Poznan

Community Forest Management (CFM) in developing countries has become an important topic in the global discourse on climate change. However, deforestation as a source of carbon emissions were largely ignored under the Kyoto Protocol (KP) and few opportunities appeared to be available for communities managing forests to benefit from this. Now there appear to be new opportunities arising for forests, and more specifically for CFM, under the proposed Reducing Emissions from Deforestation and Degradation (REDD) policy. This paper analyses the emission mitigating role of forests under the proposed REDD policy and tries to analyse some of the main issues that need to be addressed (and raised at CoP 14) to enable communities who are managing forests to benefit. The main areas to be addressed are: a) carbon accounting criteria, b) baseline construction, and c) indigenous people's rights. Suggested ways forward on all these are proposed.

Site-specific infrared O-H absorption coefficients for water substitution into olivine

Abstract There are four ways by which OH- commonly substitutes into olivine, namely those associated with (1) Si vacancies, (2) Mg vacancies, (3) Ti, or (4) trivalent cations. The four mechanisms, which we label [Si], [Mg], [Ti], and [triv], respectively, may each be fingerprinted by their characteristic O-H stretching modes in the infrared spectrum. We show by comparing the integrated intensities of these characteristic infrared peaks against total water content analyzed by secondary ion mass spectrometry, obtained for a suite of synthetic olivines plus one natural olivine, that the different substitution mechanisms require different absorption coefficients (k). For [Ti], we find k = 0.18 ± 0.07, identical to the value previously obtained from natural olivines in which the water was mainly associated with [Ti] defects. Values of k for [Si] and [triv] are 0.57 ± 0.04 and 0.18 ± 0.05, respectively; that for [Mg] is too small to be accurately determined (0.03 ± 0.03). The values of k for [Ti] and [Si] defects differ by a factor of three even though their average wavenumbers are virtually the same. The [Ti] and [triv] defects, on the other hand, have very similar absorption coefficients at significantly different wavenumbers. This highlights the inadequacy of using wavenumber-dependent calibrations for olivine and presumably for NAMs in general. Different substitution mechanisms have their own crystallographic environments that determine their absorption coefficients. The large variation in absorption coefficients within a single mineral emphasizes the importance of distinguishing the substitution mechanism if meaningful quantitative results are to be obtained from infrared spectroscopy.
ANTIBIOTIC RESISTANCE PROFILES OF BACTERIAL PATHOGENS FROM PRIVATE HOSPITALS IN DAR ES SALAAM, TANZANIA

Objective: This study aimed to determine the prevalence rates of antibiotic resistance among pathogenic bacteria to widely used antibiotics. Methods: Bacterial pathogens isolated from clinical specimens were identified by microbiological conventional methods (biochemical and colony growth morphologies) then subjected to antimicrobial sensitivity testing against the antibiotics using Kirby-Bauer disk-diffusion method against 9 widely used antibiotics viz. Chloramphenicol(C30), Amoxicillin (AX25), Gentamicin (CN10), Cefuroxime (CXM30), Ciprofloxacin (CIP5), Amoxyclav (AMC30), Doxycycline (DOC30), Ceftriaxone (CRO30) and Ampicillin (AM10). Results: A total of 304 bacterial isolates of were tested, of those 204(67.1%) were from mid-stream urine. The most frequently isolated bacteria were Escherichia coli (57.2%; n=174), trailed by Staphylococcus aureus (15.4%; n=47) and only 9(3.0%) Proteus spp. Overall, 45.5% bacterial isolates were resistant to at least two of the antibiotics. About 60.0 % (n=182) of pathogenic bacteria were susceptible to CIP5 and only 15.5 % (n=47) isolates were sensitive to AM10, 16.4% (n=50) to DOC30 and 17.8% (n=54) to AX25. Conclusion: The clinical isolates exhibited high prevalence rates of antibiotic resistance ranging from 60-70% to AM10, AX25 and AMC30 in this order. The observed high prevalence rate of antibiotic resistance emphasizes the need for routine antibiotic susceptibility testing and surveillance to avoid treatment failure and spread of antibiotic resistance.
Hydratation de la surface de Mars à partir des données du rover Curiosity

La recherche des phases hydratees a la surface de Mars est essentielle a la comprehension de son passe habitable et des changements climatiques globaux qu'elle a subis. Le rover MSL/Curiosity apporte de nouveaux moyens pour caracteriser l’hydratation de la surface. En particulier, la spectroscopie de plasma induite par laser (LIBS) de l’instrument ChemCam mesure la composition elementaire a distance. Il permet une detection de l'hydrogene par le pic d'emission H Balmer alpha a 656.6 nm. Cependant la quantification de cet element n'a ete que tres peu etudiee. Le modele de qualification de l'instrument ChemCam a ete integre a un banc LIBS afin d’analyser des series d'echantillons hydrates au laboratoire. A l’exception de quelques echantillons revelant des phenomenes specifiques a l’hydrogene, ces tests montrent qu’un etalonnage lineaire est obtenu avec la teneur en eau. Sur Mars, dans le cratere Gale, cette calibration revele l'hydratation de differentes phases : la bassanite (CaSO4 × 0.5H2O) dans les veines remplissant les fractures des roches, les sulfates de magnesium, les sediments opaliferes et argileux decouverts in situ. Les mesures d’abondances en eau effectuees jusqu’a present etaient restreintes a de rares experiences de pyrolyse ; cette etude montre que ChemCam apporte maintenant un nouveau moyen operationnel pour la mesure de l’hydrogene a la surface, a l'echelle submillimetrique et couvrant un tres grand nombre de roches.
NN-PRED: A Novel Consensus Secondary Structure Prediction Program Using Neural Networks NN-PRED: Un Nuevo Programa para la Predicción de la Estructura Secundaria de la Proteína Usando Redes Neuronales

In this paper, a new program for protein secondary structure prediction is proposed. The program, which is called NN-Pred, allows multiple sequences to be submitted and it returns predictions from five secondary structure prediction algorithms. In addition, NN-Pred calculates a consensus prediction, which is based on a neural network strategy that is used in this paper to improve the prediction accuracy. NN-Pred was obtained by using a methodology called consensus strategy, which tries to make a better prediction by integrating some of the most remarkable existing techniques. The NN-Pred program provides a three-state (alpha-helix, beta-sheet, and other) prediction of secondary structure. According to the test sets, the prediction accuracy of NN-Pred is at least 70%, surpassing most of the existing methods. The experiments showed that neural networks can be used as a consensus strategy to producing accurate models for protein secondary prediction.
A design framework for additive manufacturing based on the integration of axiomatic design approach , inverse problem-solving and an additive manufacturing database

Additive manufacturing has emerged as an integral part of modern manufacturing because of its unique capabilities and has already found its applications in various domains such as aerospace, automotive, medicine, and architecture. In order to take the full advantage of this breakthrough manufacturing technology, it is imperative that practical design frameworks or methodologies are developed. Consequently, Design for Additive Manufacturing (DfAM) has risen to provide a set of guidelines during the product design process. The existing DfAM methods have certain limitations in that the capabilities of an additive manufacturing process are not effectively considered in the early design stage, and most of them rely on the direct application of existing methods for conventional manufacturing. Furthermore, existing DfAM methods lack suitability for additive manufacturing novices. To tackle these issues, this study develops a design framework for additive manufacturing through the integration of axiomatic design approach and theory of inventive problem-solving (TRIZ) with the consideration of additive manufacturing environment. This integrated approach is effective because an axiomatic design approach can be used to systematically define and analyze a design problem, while the inverse problem-solving approach of TRIZ combined with an additive manufacturing database can be used as an idea generation tool that can generate innovative solutions for the design problem. Two case studies are presented to apply and validate the proposed design framework.
Integration Of Mutation And Gene Expression Data To Identify Disease Subtypes

Understanding the biological insights hidden in the vast amount of data collected, while investigating a disease, is the main goal for collecting such data in the first place. Changes in the gene expression or the function of proteins are important components in progression of a disease and is a key to understanding the disease mechanism. However, more often than not, the causes of such changes are not easily identified. In many cases, genetic variants may cause some of the observed gene expression changes. In this thesis, we focus on identifying the variants that significantly alter gene expression for an individual by integrating genetic variant data, gene expression data, as well as a priori knowledge about gene-gene interaction networks from multiple databases. Here we show that one can use variants that change gene expression to identify subgroups of patients with significantly different survival profiles. The method is validated on four different cancer types (renal, lung, colorectal cancer and leukemia) from the TCGA database. The results show that this method is able to identify variants that significantly affect the gene expression (and in turn the phenotype), as well as identify disease sub-types that are biologically meaningful as validated by survival and pathway analysis.
Female physiology meets psychology: menstrual cycle and contraceptive pill effects

In dit proefschrift toon ik aan dat het gebruik van hormonale contraceptie (HC) de natuurlijke hormonale fluctuaties verstoort, wat negatieve psychologische gevolgen kan hebben voor sociale relaties. Onderzoek naar de gevolgen van HC op gedrag in sociale relaties draagt mogelijk bij aan meer geinformeerde keuzes door vrouwen om HC te gebruiken alsmede aan de ontwikkeling van nieuwe HC. Dit onderwerp heb ik vanuit een evolutionair psychologische perspectief benaderd. Dit perspectief bood theoretische inzichten wat betreft de te verwachten gedragsveranderingen ten gevolge van het gebruik van HC. Uit twee studies bleek dat vrouwen een hogere mate van jaloezie rapporteren wanneer zij zich in de vruchtbare fase van hun menstruele cyclus bevinden dan wanneer zij zich in de onvruchtbare fase bevinden. Verder was het zo dat vrouwen met partner, maar niet vrouwen die single zijn, een hogere mate van jaloezie rapporteren wanneer zij HC gebruiken in vergelijking met vrouwen die een normale menstruele cyclus hebben. Ook toonde ik aan dat vrouwen die HC gebruiken meer jaloezie rapporteren wanneer deze hogere doses van synthetisch oestrogeen bevatten. Ten slotte onderzocht ik de invloed van huidig HC gebruik in relatie tot het HC gebruik bij aanvang van een romantische relatie. Ik vond dat vrouwen wiens huidige HC overeenstemde met het gebruik dat tijdens de aanvang van de romantische relatie minder jaloers waren dan vrouwen bij wie dit niet overeenstemde. Naast bevindingen omtrent jaloezie, vond ik in twee vervolgstudies dat de competitie tussen vrouwen lager is bij vrouwen die HC gebruiken dan bij vrouwen die een normale menstruele cyclus hebben, en dat mannen hun partner en zichzelf als aantrekkelijker zien rond de ovulatie dan tijdens een periode van HC gebruik door hun partner.
Survey of persistent organochlorine contaminants (PCDD, PCDF, dl-PCB) in Baltic fish and fish meals.

The concentration and congener-specific profile of polychlorinated dibenzo-p-dioxins (PCDD), polychlorinated dibenzofurans (PCDF), and dioxin-like polychlorinated biphenyls (dl-PCB), were determined in edible marine fish tissues of salmon, herring, and in sprat and fishmeals collected between 2006 and 2008. Average concentrations of the sum of the compounds ranged from 4.05 ±5.46 to 9.23 ±2.64 pg WHO-TEQ/g f.w. for the tested fish species. The highest concentration was found in salmon – up to 11.39 pg WHO-TEQ/g f.w. of the sum of PCDD, PCDF, and dl-PCB. Only seven out of 55 fish meals exceeded the maximum permitted level for PCDD/PCDF (over 1.25 ng WHO-TEQ/kg) and 4 pg/p for total TEQ. Dioxin-like PCB make up about 50% of the concentration. The PCDD, PCDF, and dl-PCB accumulation pattern found in the analysed samples showed typical distribution reported for marine samples. The following congeners dominated: 2,3,7,8-PCDF, 2,3,4,7,8-PeCDF, 1,2,3,7,8-PeCDF, and PCB 105,118, and 156.
The use of different concentrations of leishmanial antigen in skin testing to evaluate delayed hypersensitivity in american cutaneous leishmaniasis

Three concentrations of Leishmania mexicana amazonensis sonicated whole promastigote antigen (30, 9.6 and 3 ug N in 0.1 ml) wereprepared and 0.1 ml of each inoculated intradermally intopatients who live in one endemic leishmaniasis region in Brazil. Patients were divided into groups with active cutaneous leishmaniasis (ACL), healed cutaneous leishmaniasis (HCL), mucosal leishmaniasis (ML), and Controls (C). Skin reactions were recorded by measuring induration 48 hours after inoculation. Skin tests using 9.6 ugN/0.1 mlyielded the best diagnostic resultssince 97% of 30 patients with active lesions (cutaneous or mucosal) and 83% with HCL showed reactions of 5 mm orgreater as compared with 4% Controls. Tests using 30ug N/O. 1 ml causedan unacceptable levei of skin reactions with necrosis (10% of ACL patients tested and 17% of HCL, respectively). Tests using 3 ug N/O. 1 ml were less sensitive since only 87% of patients with active lesions and 68% with HCL had reactions of 5mm orgreater. The 3 ug N/O. 1 ml dose was utilized to ask the questions whether skin delayed hypersensitivity decreased with time after the initial lesion and whether mucosal involvement is associated with enhaced hypersensitivity to leishmanial antigen. Decreased delayed hypersensitivity was noted only in those patients who had an initial lesion more than 30 years ago. The mean induration of the reaction in 10 patients with ML was 11.3 mm ± 7.15, in 41 patients with HCL, 9.27 mm ± 6.78 and in 20patients with ACL 10. 7 mm ± 6.10 mm. The percent of patients with 5 mm orgreater induration was ML 80%, HCL 71%, ACL 90%. Thus, we could not confirm an association between enhanced delayed hypersensitivity and mucosal involvement in leishmaniasis.
Focus on the Outcomes of Communication Under Six

The present study was conducted to evaluate the reliability of the FOCUS© (Focus on the Outcomes of Communication Under Six). The FOCUS© is intended to measure the functional change in real-world communication associated with speech-language therapy. Clinicians administer this test by interviewing parents before and after treatment. The inter-rater reliability of detected change was high when evaluating preschool children (n = 13). Results indicate that this measure is reliable for both practical and research purposes. The necessity of establishing reliability is discussed, as are limitations of the FOCUS©.

Modeling of a Topology Adaptive Clustering Algorithm for Mobile Ad Hoc Networks using Coloured Petri Nets

The modeling of a communication protocol for a distributed computing system requires making clear inputs and outputs of the remote communicating entities and the formal modeling of the communication channel in the aim of protocol verification or validation. Petri nets are the formal tool which is mostly used for the purpose of modeling and validation. The coloured Petri Net model of a system can be an executable model representing the different states of the system as well as the events that can cause the system to change its states. In this paper we model a distributed topology adaptive clustering algorithm for mobile ad hoc networks by using the coloured petri net tools.
Education Quality and Labour Market Outcomes in South Africa

In this paper we include measures of school quality in regressions determining the labour market premiums to education level. We use the matric exemption score and the pupil/teacher ratio of the respondents’ closest school during childhood as proxies for education quality. We find that the employment and earnings premiums to education level are robust to the inclusion of these quality measures. Moreover, there is a significant direct relationship between our quality measures and earnings, controlling for education level. Increasing the matric exemption score by 10 percentage points increases earnings, on average, by 8% and decreasing the pupil/teacher ratio by one learner is associated with a 1% increase in earnings. No significant relationship is found between the school quality measures and employment.This Working Paper relates to the 2013 OECD Economic Survey of South Africa, www.oecd. org/eco/surveys/listofeconomicsurveysofsouthafrica.htm. Qualite de l'education et rendement sur le marche du travail en Afrique du Sud Dans cette etude nous incluons des variables de qualite de l’education dans les regressions determinant le rendement sur le marche du travail des niveaux d’education atteints. En guise de mesure de la qualite, nous utilisons le taux de reussite au diplome final d’etudes secondaires ainsi que le ratio eleve/enseignant de l’ecole la plus proche du lieu de residence de l’individu sonde durant sa jeunesse. Nous trouvons que les effets des niveaux educatifs sur les salaires et les probabilites d’avoir un emploi sont robustes a l’inclusion de ces variables de qualite de l’education. De plus, il y a une relation directe significative entre nos variables de qualite et les salaires apres controle pour le niveau educatif atteint. Augmenter le taux de reussite de l’ecole de 10 points de pourcentage augmente les salaires d’en moyenne 8%, tandis que diminuer le ratio eleve-enseignant d’un eleve augmente les salaires de 1%. Aucune relation robuste n’est exhibee entre les mesures de qualite de l’education et l’emploi.

Analysis of a Novel Four Level Flying Capacitor H – Bridge Converter

In this paper, a novel four-level flying capacitor inverter and its comparison with the conventional flying capacitor topology in terms of THD analysis are proposed. This new topology have some advantages over conventional one as following: The blocking voltages are the same for all switches used in the configuration, there is no need for capacitor midpoint connection and this eliminates low frequency current which circulate in dc-link capacitors, and the number of flying capacitor is reduced as compared with conventional form of it. The operation of the topology, modulation strategy, simulation results, and THD analysis for the output waveforms are presented in this paper.

The Effects of Entrepreneurial Growth Orientation on Organizational Change and Firm Growth

Abstract Managing growth in an enterprise as it grows beyond the startup phase is a challenge for many entrepreneurs. One key element that can help or hinder growth is the entrepreneur. Entrepreneurial growth has been linked to micro variables (motivations and psychological attributes of the entrepreneur) and macro variables. However, few studies have examined the role of the growth aspirations of the entrepreneur on the necessary elements of organization change related to growth. This paper reports a study employing a typology of entrepreneurs based on their growth aspirations using an established dichotomous scale devised by Smith to differentiate between what he called craftsmen versus opportunistic entrepreneurs. The findings, while not supporting all expectations, do support the literature that points to the growing importance of intellectual capital, technological upgrading and participative management approaches as competitive weapons of small firms.
Inversion of higher order isotropic tensors with minor symmetries and solution of higher order heterogeneity problems

In this paper, the derivation of irreducible bases for a class of isotropic 2nth-order tensors having particular ‘minor symmetries’ is presented. The methodology used for obtaining these bases consists of extending the concept of deviatoric and spherical parts, commonly used for second-order tensors, to the case of an nth-order tensor. It is shown that these bases are useful for effecting the classical tensorial operations and especially the inversion of a 2nth-order tensor. Finally, the formalism introduced in this study is applied for obtaining the closed-form expression of the strain field within a spherical inclusion embedded in an infinite elastic matrix and subjected to linear or quadratic polynomial remote strain fields.
