Segmentovaná diskrétní waveletová transformace / Segmentwise Discrete Wavelet Transform

Průša, Zdeněk January 2012 (has links)
Dizertační práce se zabývá algoritmy SegDWT pro segmentový výpočet Diskrétní Waveletové Transformace – DWT jedno i vícedimenzionálních dat. Segmentovým výpočtem se rozumí způsob výpočtu waveletové analýzy a syntézy po nezávislých segmentech (blocích) s určitým překryvem tak, že nevznikají blokové artefakty. Analyzující část algoritmu pracuje na principu odstranění přesahu a produkuje vždy část waveletových koeficientů z waveletové transformace celého signálu, které mohou být následně libovolně zpracovány a podrobeny zpětné transformaci. Rekonstruované segmenty jsou pak skládány podle principu přičtení přesahu. Algoritmus SegDWT, ze kterého tato práce vychází, není v současné podobně přímo použitelný pro vícerozměrné signály. Tato práce obsahuje několik jeho modifikací a následné zobecnění pro vícerozměrné signály pomocí principu separability. Kromě toho je v práci představen algoritmus SegLWT, který myšlenku SegDWT přenáší na výpočet waveletové transformace pomocí nekauzálních struktur filtrů typu lifting.

The Association between Childhood Maltreatment, Substance Use Frequency, and Physical Intimate Partner Violence: A Gene-Environment Study

Aura Ankita Mishra (8905460) 15 June 2020 (has links)
<p>This dissertation evaluated the complex inter-relatedness between co-occurring childhood maltreatment exposures, physical intimate partner violence (perpetration and victimization), substance use frequency, and molecular genetics for substance use, utilizing appropriate developmental models and theoretical approaches. Three studies were proposed within this dissertation. Data for the three studies come from a national longitudinal panel study: The National Longitudinal Study of Adolescent to Adult Health (Add Health; Harris, 2013). Across studies, latent profile analysis was used to evaluate co-occurring childhood maltreatment exposures based on type and severity of exposures, which resulted in three homogenous sub-groups. The first sub-group was composed of individuals that had high levels of physical abuse exposure and moderate levels of childhood neglect and emotional abuse exposures (high physical abuse sub-group). The second sub-group (high sexual abuse sub-group) included individuals with high severity of sexual abuse exposure and moderate severity of all other childhood maltreatment types (i.e., physical abuse, emotional abuse, and neglect). This second sub-group was, therefore, the most vulnerable in terms of their childhood maltreatment exposure. A final normative sub-group was also found that included a majority of individuals with low severity of childhood maltreatment exposure across types. Additionally, across all three studies, a probabilistic multifaceted genetic risk score (i.e., polygenic risk score) was created to evaluate substance use related genetic risk. The first study evaluated the role of co-occurring childhood maltreatment exposure on substance use development from adolescence to young adulthood while evaluating substance use related genetic moderation. Generalized estimating equations were used to test the proposed model in study 1. Findings suggest that the high physical abuse sub-group was more susceptible to genetic risk and had increases in substance use frequency only at high levels of genetic risk. In contrast, for the high sexual abuse sub-group, childhood maltreatment and environmental exposures were more ubiquitous for substance use development from adolescence to young adulthood. To elaborate, the high sexual abuse sub-group demonstrated increases in substance use from adolescence to young adulthood irrespective of genetic risk. In study 2, substance use frequency in young adulthood was tested as a mechanism between childhood maltreatment sub-groups and subsequent physical intimate partner violence perpetration in adulthood. Once again, genetic moderation for the direct association between childhood maltreatment sub-groups and substance use frequency in young adulthood was tested within the larger mediation model. In study 3, physical partner violence victimization in young adulthood was tested as a mediator of the association between childhood maltreatment sub-groups and substance use frequency in adulthood. In study 3, in addition to the above-mentioned genetic risk score, an additional substance use related dopamine polygenic risk score was also tested. Specifically, in study 3, genetic moderation by both genetic risk scores was tested on 1) the direct pathway from childhood maltreatment sub-groups to substance use frequency in adulthood, and 2) the direct pathway from physical intimate partner violence victimization in young adulthood to substance use frequency in adulthood. In both studies 2 and 3, product of co-efficient method was used to estimate mediation hypothesis, and moderated-mediation models were used to test for genetic moderation within the mediation model. Research aims for studies 2 and 3 were largely not supported. However, supplementary models indicate that substance use frequency may not be a causal mechanism but may be a contextual factor exacerbating the association between childhood maltreatment exposures and physical intimate partner violence perpetration. Implications for findings are discussed in detail. </p>

Phenomenological studies of dimensional deconstruction

Hällgren, Tomas January 2005 (has links)
In this thesis, two applications of dimensional deconstruction are studied. The first application is a model for neutrino oscillations in the presence of a large decon- structed extra dimension. In the second application, Kaluza{Klein dark matter from a latticized universal extra dimension is studied. The goal of these projects have been twofold. First, to see whether it is possible to reproduce the relevant features of the higher-dimensional continuum theory, and second, to examine the effect of the latticization in experiments. In addition, an introduction to the the- ory of dimensional deconstruction as well as to the theory of continuous extra dimensions is given. Furthermore, the various higher-dimensional models, such as Arkani-Hamed{Dvali{Dimopolous (ADD) models and models with universal extra dimensions, that have been intensively studied in recent years, are discussed. / QC 20101202

Reedukace motorických obtíží u dětí mladšího školního věku / Re-education of children with motor difficulties of primary school age

Tichý, Pavel January 2016 (has links)
BIBLIOGRAPHIC IDENTIFICATION Name and surname of the author: Mgr. Pavel Tichý Name of the dissertation: Re-education of children with motor difficulties of primary school age Workplace: FTVS UK, Department of Sport Games Supervisor of the work: Doc. PhDr. Vladimír Süss, Ph.D. Year of presentation: 2016 ABSTRACT Objective: The aim was to find out the possibility of the re-education of motor difficulties in children of primary school age and create a re-education intervention program, the aim of which is to reduce these difficulties. Subsequently, to verify whether the intervention program had an effect on the motor difficulties of the children. Method: The research was designed as a prospective intervention study where there were two combined orientations ofeducational research: quantative and qualitative. To solve the problem a research design was used, called Crossover Design (Wilmore et al., 2008, Thomas et al., 2005), which was conceived as an experiment with an intervention re-education program aimed at improving the motor difficulties of children. The quantative part of the research was focused on the assessment of motor skills and to detect motor problems in children of primary school age. MABC-2 (Henderson et al., 2007) battery of motor tests were used for this purpose. The qualitative part of the...

Higher Radix Floating-Point Representations for FPGA-Based Arithmetic

Catanzaro, Bryan Christopher 22 April 2005 (has links) (PDF)
Field Programmable Gate Arrays (FPGAs) are increasingly being used for high-throughput floating-point computation. It is forecasted that by 2009, FPGAs will provide an order of magnitude greater sustained floating-point throughput than conventional processors. FPGA implementations of floating-point operators have historically been designed to use binary floating-point representations, as do general purpose processors. Binary representations were chosen as the standard over three decades ago because they provide maximal numerical accuracy per bit of floating-point data. However, the unique nature of FPGA-based computation makes numerical accuracy per unit of FPGA resources a more important measure of the usefulness of a given floating-point representation. From this viewpoint, higher radix floating-point representations are well suited to FPGA-based computations, especially high precision calculations which require the support of denormalized numbers. This work shows that higher radix representations lead to more efficient use of FPGA resources. For example, a hexadecimal floating-point adder provides a 30% lower Area-Time product than its binary counterpart, and a hexadecimal floating-point multiplier has a 13% lower Area-Time product than its binary counterpart. This savings occurs while still delivering equal worst-case and better average-case numerical accuracy. This work presents a family of higher radix floating-point representations that are designed specifically to interoperate with standard IEEE floating-point, allowing the creation of floating-point datapaths which operate on standard binary floating-point data, yet use higher radix representations internally. Such datapaths provide higher performance by any measure: they are more accurate numerically, consume less FPGA resources and have shorter latencies. When taking into consideration the unique nature of FPGA-based computing systems, this work shows that binary floating-point representations are not optimal for most FPGA-based arithmetic computations. Higher radix representations can therefore be a useful tool for building efficient custom floating-point datapaths on FPGAs.

Mellan stolarna, upp på väggarna : att få plats i en skola för alla

Sundhage Lif, Lea Johanna January 2016 (has links)
The purpose of this study was to investigate how well adjusted the support is for young people that have been diagnosed with ADHD, while attending the gymnasium. Analysis and result are based on a sociocultural perspective and have their take-off in literaturestudies and qualitative interviews with two students with the diagnosis and one special needs teacher. The interviews were based on themes that had their starting point in school policy documents and related literature. The interviews were semi-structured with the aim of letting the interviewees speak as freely as possible. One of the themes included the individual strategies developed by the interviewees, such as using mobile-apps to help structure and plan for everyday life. Results show that the available support is not well adapted and that how great impact the ADHD-diagnosis has on how well the person do in school is greatly affected by in what social context and what kind of support he or she has outside of school, for example by family. The study shows that there is great need for further research and development within the research area. / Syftet med den här studien var att undersöka hur väl anpassat stödet i gymnasieskolan är för elever med ADHD-diagnos. Analys och resultat är bearbetade utifrån ett sociokulturellt perspektiv och baseras på litteraturstudier och kvalitativa intervjuer med två gymnasieelever med ADHD-diagnos samt en specialpedagog/speciallärare. Intervjuerna berörde teman med utgångspunkt i styrdokumenten samt i relaterad litteratur och var halvstrukturerade, med syftet att låta intervjupersonerna tala så fritt som möjligt. Ett av temana berörde de egna strategier som intervjupersonerna utarbetat, så som att använda appar i mobilen för att skapa struktur och planera vardagen. Resultatet visar att stödet i gymnasieskolan inte är väl anpassat utan att hur väl en person med ADHD-diagnos klarar sig i skolan snarare beror på de omgivande förutsättningarna utanför skolan, exempelvis vilket stöd hen får från sin familj. Studien visar att det finns stor utvecklingspotential inom området och att det behövs ytterligare forskning på hur man kan omforma skolans sociokulturella struktur och se till att anpassningarna blir just anpassningar och inte ytterligare krav.
