It is worth noting that this program emerges the need of big business and the state to offer a response to local entrepreneurs and society in order to integrate them into the supply chains of large companies. However, to this end, we draw the path from the change in the economy, taking as starting point the private sector, which adopts the restructuring process as this new flagship model, the unbundling of the leading chains of large companies, mainly through outsourcing, thus generating a strategy of regional specialization. Given these changes, turns to examine the paradigm in relation to the State, which is undergoing deep changes, culminating with the so-called Minimum or Neoliberal State. It should be emphasized that the evaluation of the MA-developed PDF is dynamic and want to go from the general international economic relations, through the reflections of these relations in Brazil, reaching the more specific, the program exposed. Finally, the study of the PDF-MA aims to detail the dynamics of the program, building a framework of indicators and developing the theme of Sustainable Development. To undertake such research were two moments evaluative, first we make a political assessment of the policy, so you can figure out the nuances and how its implementation was determined politically, understanding how the program came into the government's agenda and what subjects interest and rationalities involved. In the second, reveals the dynamics of implementation of this policy through an evaluation process, ensuring that the means used are appropriate to the desired ends and if it was able to change the situation that gave rise to the problem program. Along the way, we used a qualitative and quantitative approach, having as research techniques, literature and documentary mode. Thus, we intend to unveil a new vision for the PDF-MA. / Esta dissertação tem como objeto a formulação e a implementação do Programa de Desenvolvimento de Fornecedores do Estado do Maranhão. Vale destacar, que este programa emerge da necessidade das grandes empresas e do Estado de oferecerem uma resposta para os empresários locais e a sociedade no sentido de integra-lós às cadeias produtivas das grandes empresas. No entanto, para atingir essa finalidade, traça-se o caminho a partir da mudança na economia, tendo como ponto inicial o setor privado, que adota a reestruturação produtiva como carro chefe desse novo modelo, levando à desverticalização das cadeias das grandes empresas, principalmente por meio da terceirização, gerando, assim, uma estratégia de especialização regional. Dadas essas transformações, volta-se para analisar o paradigma em relação ao Estado, que passa por profundas alterações, culminando com o denominado Estado Mínimo ou Neoliberal. É necessário ressaltar que a avaliação do PDF-MA desenvolvida é dinâmica e pretende ir desde o geral, as relações econômicas internacionais, passando pelos reflexos dessas relações no Brasil, chegando ao mais específico, o programa exposto. Enfim, no estudo do PDF-MA pretende-se detalhar a dinâmica do programa, construindo um quadro de indicadores e desenvolvendo a temática do Desenvolvimento Sustentável. Para empreender tal investigação ocorreram dois momentos avaliativos, primeiro faz-se uma avaliação política da política, para que seja possível perceber quais as nuances e como foi determinado politicamente sua implementação, entendendo como o programa entrou na agenda do governo e quais os sujeitos, interesses e racionalidades envolvidas. No segundo, desvenda-se a dinâmica de implementação dessa política pública, por meio de uma avaliação de processo, verificando se os meios utilizados estão adequados aos fins desejados e se este foi capaz de alterar a situação problema que deu origem ao programa. Nesse percurso, utilizou-se de uma abordagem qualitativa e quantitativa, tendo como técnicas de pesquisa, a modalidade documental e a bibliográfica. Dessa forma, pretende-se descortinar uma nova visão sobre o PDF-MA.

Att fakturera är något som alla företag måste göra för att tjäna pengar. Fakturering kan ske på flera olika sätt och det finns olika åsikter vad som är att föredra bland företag när det handlar om hantering av fakturor. Teorin menar på att använda sig av elektroniska faktureringssätt är mer effektivt än fakturering via traditionell post. Syftet med denna forskning var att ta reda på varför företag i Sverige år 2015 väljer att skicka, mottaga och hantera fakturor med post när det finns alternativa metoder som PDF via mail och vad det är som gör att företag inte byter från det ena förhållningssättet till det andra. / To invoice is something that all companies must do to earn money. Invoicing can be done in several ways and there are different opinions in what is to be preferred among companies when it comes to handling invoices. However the theory argues, that the use of the electronic invoicing method is more effective than invoicing through traditional mail. The purpose of this study was to find out why companies in Sweden in 2015 choose to send, receive and manage invoices by email when there are alternative methods as PDF through email and what it is that makes companies not change from one approach to another.

Les matériaux poreux silicatés ont été mis à profit pour encapsuler différents types de molécules, clusters ou nano-objets fonctionnels, donnant lieu à des nanocomposites hybrides organiques-inorganiques à propriétés physiques, chimiques ou biologiques remarquables. Élucider l'organisation structurale à l'échelle moléculaire de tels nanocomposites est indispensable pour l'analyse et la compréhension des propriétés macroscopiques qui en découlent. Ainsi, les techniques de diffusion totale associées à la fois à l'analyse Debye et la Fonction de Distribution de Paires (PDF) sont des méthodes de choix pour la caractérisation des propriétés structurales de matériaux hybrides nano-structurés. Le principal objectif de ce travail consiste à l'utilisation des approches basées sur la diffusion totale de rayons X pour l'analyse structurale complète de molécules photoactives confinées dans des matrices silicatées amorphes avec différentes tailles de pores, afin d'étudier l'influence de l'organisation structurale sur les propriétés optiques et d'explorer également les limites de ces approches d'analyse. Nous avons étudié deux systèmes photoactifs. L'analyse structurale du premier complexe confiné, Na2[Fe(CN)5NO].2H2O (SNP), a été entreprise par une approche multi-échelle combinant la RMN du solide et l'analyse PDF. Cette approche a permis l'identification de la nature des espèces incorporées, l'arrangement des cations et des anions ainsi que la distinction des différentes phases existantes : molécules isolées et nanoparticules. Les analyses Debye et PDF sur le deuxième composé étudié, [NdCl2(H2O)6]Cl, montrent que l'organisation structurale du complexe confiné est différente de celle du matériau massif cristallin. De plus, les cations Nd3+ changent de coordination de 8 à 9 durant le processus d'imprégnation et adoptent ainsi un arrangement structural très similaire à celui en solution aqueuse. Cette modification structurale est en accord avec le changement des propriétés luminescentes de ce complexe / Silica xerogels are versatile host materials for the inclusion of molecules, clusters, or nano-objects yielding host-guest compounds with unique physical, chemical or biological properties. The knowledge of the structural organization of the guest within the host is crucial for the understanding of its properties. Total scattering methods, based on Debye function analysis (DFA) and Pair Distribution Function (PDF), have become powerful tools for structural characterization of nanostructured hybrid materials. The aim of this work is to use the X-ray total scattering method to obtain structural information on photoactive molecules embedded into amorphous silica hosts with different pore sizes, to correlate their structure with the optical properties, and to explore the limitations of the chosen method. Two different photoactive complexes have been investigated. In the first example, the combined PDF and NMR study on Na2[Fe(CN)5NO].2H2O (SNP) embedded into silica matrices allows to extract the nature of the inserted species: quasi-free isolated molecules can be distinguished from nanoparticles and in the former case a model for the arrangement of cation-anion can be proposed from the PDF analysis. In the second example, a luminescent Nd3+ complex, the PDF and DFA analysis reveal that the structural organization of the embedded Nd3+ complexes is different from that of the crystalline material. Furthermore, the Nd3+ cations change the coordination from 8 to 9 during the wet-impregnation doping and adopt very similar structural arrangement as in aqueous solution, which is in agreement with the observed change in the luminescence properties

This master's thesis analyses fluid flow in an open cylindrical tank with vortex using numerical simulation. The theoretical part introduces a set of equations governing fluid flow and relations used to describe vortex motion. A general overview of terms used in computational fluid dynamics is presented. The experimental section consists of three parts. The vortex modelling is performed using ANSYS Fluent software. Data are consequently analysed within ANSYS CFD-Post software tool. Special focus is put on the vortex shape that is fitted with a curve corresponding to a probability density function of the Cauchy distribution. Results are then plotted in MATLAB software.

The progress of blended learning has given rise to the need to prepare quality electronic materials, especially those which use the greatest advantage of an electronic document – its interactivity. This paper presents several types of PDF materials – interactive exercises, tests and games created by LaTeX packages (AcroTeX eDucation Bundle) with a contribution of other supporting instruments (3D graphics, fancytooltips, AcroFLeX). Differential equations, as an important tool of continuous mathematical modeling, have been chosen to demonstrate the still increasing power of PDF documents. This strategy allowed me to introduce innovative approaches in explaining and exercising this part of mathematics at the same time. To create such materials some LaTeX knowledge is needed; nevertheless this article is for all math teachers who are looking for quality interactive materials.

Die in MEDIBUS organisierten Blindenbüchereien sehen sich als Partner der kommerziellen Verlagswelt und nicht als deren Konkurrenten. Die sehr geringen Auflagenhöhen und die speziellen Anforderungen bei der Aufbereitung von Literatur in Brailleschrift und Großdruck wecken in aller Regel nur wenig verlegerisches Interesse. Die wachsende Auswahl an mobilen Endgeräten, Medienkonvergenz und Diversifikation von Angeboten sind Chancen der digitalen Revolution, die es ermöglichen, auch Menschen mit speziellen Bedürfnissen zeitnah und in adäquater Qualität Wissen zugänglich zu machen. libreka! und die DZB kooperieren im Projekt „Leibniz – Sach- und Fachbuchaufbereitung für Blinde und Sehbehinderte“, um PDF- und Satzdaten zu verarbeiten und deren digitale Verbreitung sowohl für sehende als auch für nichtsehende Leserinnen und Leser zu forcieren. DAISY-Standards und -Technologien sind dabei der Schlüssel zum Erfolg.

In this presentation, various projects at DZB will be described, concerning various collaborations with publishing houses and Libreka! – an online platform of the German association of publishers “Börsenverein des Deutschen Buchhandels”, to improve the workflow of transformation of typesetting data into the DAISY 3 format. By developing adaptive content processing facilities, this data can be used to increase the availability of publications in Braille, DAISY and large Print.

The Portable Document Format (PDF) is an ideal format for viewing and printing documents. Today many companies store their documents in a PDF format. However, the conversion from a PDF document to any other structured format is inherently difficult. As a result, a lot of the information contained in a PDF document is not directly accessible - this is problematic. Manual intervention is required to accurately convert a PDF into another file format - this can be deemed as both strenuous and exhaustive work. An automated solution to this process could greatly improve the accessibility to information in many companies. A significant amount of literature has investigated the process of extracting information from PDF documents in a structured way. In recent years these methodologies have become heavily dependent on computer vision. The work on this paper evaluates how the U-Net model handles multi-label segmentation on PDF documents in a medical context - extending on Stahl et al.’s work in 2018. Furthermore, it compares two newer extensions of the U-Net model, MultiResUNet (2019) and SS-U-Net (2021). Additionally, it assesses how each of the models performs in a data-sparse environment. The three models were implemented, trained, and then evaluated. Their performance was measured using the Dice coefficient, Jaccard coefficient, and percentage similarity. Furthermore, visual inspection was also used to analyze how the models performed from a perceptual standpoint. The results indicate that both the U-Net and the SS-U-Net are exceptional at segmenting PDF documents effectively in a data abundant environment. However, the SS-U-Net outperformed both the U-Net and the MultiResUNet in the data-sparse environment. Furthermore, the MultiResUNet significantly underperformed in comparison to both the U-Net and SS-U-Net models in both environments. The impressive results achieved by the U-Net and SS-U-Net models suggest that it can be combined with a larger system. This proposed system allows for accurate and structured extraction of information from PDF documents. / Portable Document Format (PDF) är ett välfungerande format för visning och utskrift av dokument. I dagsläget väljer många företag därmed att lagra sina dokument i PDF-format. Konvertering från PDF format till någon annan typ av strukturerat format är dock svårt, och detta resulterar i att mycket av informationen i PDF-dokumenten är svårtillgängligt, vilket är problematiskt för de företag som arbetar med detta filformat. Det krävs manuellt arbete för att konvertera en PDF till ett annat filformat - detta kan betraktas som både ansträngande och uttömmande arbete. En automatiserad lösning på denna process skulle kunna förbättra tillgängligheten av information för många företag. En stor mängd litteratur har undersökt processen att extrahera information från PDF-dokument på ett strukturerat sätt. På senare tid har dessa metoder blivit starkt beroende av datorseende. Den här forskningen utvärderar hur U-Net-modellen hanterar segmentering av PDF dokument, baserat på flerfaldiga etiketter, i ett medicinskt sammanhang. Arbetet är en utökning av Stahl et al. forskning från 2018. Dessutom jämförs två nyare utökade varianter av U-Net-modellen , MultiResUNet (2019) och SS-U-Net (2021). Utöver detta så utvärderas även varje modell utefter hur den presterar i en gles datamiljö. De tre modellerna implementerades, utbildades och utvärderades. Deras prestanda mättes med hjälp av Dice-koefficienten, Jaccard-koefficienten och procentuell likhet. Vidare så görs även en visuell inspektion för att analysera hur modellerna presterar utifrån en perceptuell synvinkel. Resultaten tyder på att både U-Net och SS-U-Net är exceptionella när det gäller att segmentera PDF-dokument i en riklig datamiljö. SS-U-Net överträffade emellertid både U-Net och MultiResUNet i den glesa datamiljön. Dessutom underpresterade MultiResUNet signifikant i jämförelse med både U-Net och SS-U-Net modellen i båda miljöerna. De imponerande resultaten som uppnåtts av modellerna U-Net och SS-U-Net tyder på att de kan kombineras med ett större system. Detta föreslagna systemet möjliggör korrekt och strukturerad extrahering av information från PDF-dokument.
