Internet of things (IoT) which was once a vision is now reality in many sectors. Platform in the IoT ecosystem plays an important role in service provisioning journey by creating business value for the actors and enabling data management for the user. Service provisioning on IoT platform are application centric and is more focused on vertical development. Amalgamation of services, applications in IoT platform is the key in bringing data and society together. Interoperability and scalability is posing as hindrance for this hypothesis. On high level, identifying the cost drivers in these IoT platforms can be key for an actor to bring this hypothesis to reality. This work is one such attempt in providing cost breakdown and identifying cost drivers in IoT platform. A generic framework is proposed which dimensions the platform hardware and software to apprehend the design, development and operation cost of services considered. The framework is designed to proffer three deployment cloud strategies, On-premises, Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). Three business use cases are tested on this framework to arrive at the cost structure, which in turn states the cost drivers. The results suggest storage, hardware replacement and software development are major chunk of cost in the structure driven by devices/sensors in the platform and message transmission rate from those devices. Additionally, a suggestion of deployment strategies are made on each use cases to avail cost efficient services. / Internet of Things (IoT) som en gång var en vision är nu verklighet i många sektorer. Plattformen i IoT-ekosystemet spelar en viktig roll i researrangemanget genom att skapa affärsvärde för aktörerna och möjliggöra datahantering för användaren. Tjänsteleverantörer på IoT-plattformen är applikationscentriska och är mer fokuserade på vertikal utveckling. Sammanslagning av tjänster, applikationer i IoT-plattformen är nyckeln till att föra data och samhället samman. Interoperabilitet och skalbarhet utgör hinder för denna hypotes. På hög nivå kan identifiering av kostnadsdrivarna i dessa IoT-plattformar vara nyckeln för en aktör för att få denna hypotes till verklighet. Detta arbete är ett sådant försök att tillhandahålla kostnadsfördelning och identifiera kostnadsdrivare i IoT-plattformen. Ett generiskt ramverk föreslås som dimensionerar plattformshårdvaran och programvaran för att fånga konstruktions-, utvecklingsoch driftkostnaderna för betraktade tjänster. Ramverket är utformat för att erbjuda tre implementeringsmolnstrategier, lokala, infrastruktur som en tjänst (IaaS) och plattform som en tjänst (PaaS). Tre fall för affärsanvändning testas enligt denna ram för att komma fram till kostnadsstrukturen, vilket i sin tur anger kostnadsdrivarna. Resultaten tyder på att lagring, hårdvarutbyte och mjukvaruutveckling är en stor del av kostnaden i strukturen som drivs av enheter / sensorer i plattformen och överföringshastighet för meddelanden från dessa enheter. Dessutom görs ett förslag om distributionsstrategier för varje användningsfall för att utnyttja kostnadseffektiva tjänster.

The present study explores the correlational relationships between Social Anxiety, anxiety, depression, and stress, Subjective Online Success (SOS) and Dating Platforms classes ("quick-dating" and "full-commitment). Namely, this paper investigates: (1) whether using “full commitment” or “quick dating” dating platforms correlate with differences in , depression,anxiety, stress, and SOS; (2) whether gender influences SOS; (3) whether the class of datingplatforms influences SOS (4) the relationship between, depression, stress, anxiety, SOS andboth dating platforms (5) the relationship between SOS and social anxiety, depression, anxiety,stress, and gender. This exploratory cross-sectional study was conducted with 89 participants,which were gathered via convenience sampling. The data was analyzed with Pearson’scorrelation, independent t-tests, and simple mediation analysis by using the Hayes PROCESSextension for SPSS. Results show that Badoo users have higher scores in all the mental healthmeasures and SOS compared to Tinder users. Furthermore, there were no significantdifferences in SOS between genders, but there were significant differences in SOS betweendating platforms. Lastly, SOS mediated the relationship between relationship status anddepression, stress, and anxiety. These findings have implications for mental healthpractitioners, I.T., online dating companies, and dating platform users as they can betterunderstand the consequences of using dating platforms belonging to the two classes. / Den här studien utforskar sambandet mellan social ångest , ångest, depression och stress,subjektiv online-framgång och dejting app-typer(“quick dating”- och“full-commitment”-platformer). Mer konkret undersöker den här uppsatsen: (1) huruvidaanvändandet av “full-commitment”-DP eller “quick dating”-DP korrelerar med skillnader iSO, depression, ångest, stress och SOL; (2) huruvida kön påverkar SOL; (3) huruvidakategorierna av DP påverkar i vilken utsträckning deltagare upplever SOL, (4) hur relationenmellan SO, depression, stress, ångest, SOL och de båda dejting platformerna ser ut och (5)hur relationen mellan SOL och SO, depression, ångest, stress och kön ser ut. Den härtvärsnittsstudien bygger på data hämtat genom bekvämlighetsurval och genomfördes med 89deltagare. Datan analyserades med Pearsons korrelation, självständiga t-tester och simplemediation-analys genom användandet av Hayes processutveckling av SPSS. Resultaten visaratt Badoo-användare har högre värden i samtliga mental hälsa-undersökningar somgenomfördes jämfört med Tinder-användare. Det fanns inte heller några betydande skillnaderi SOL mellan könen, däremot så fanns det betydande skillnader i SOL mellan de olika dejtingplatformerna. Slutligen spelade SOL en roll i sambandet mellan relationsstatus ochdepression, stress och ångest. Dessa upptäckter har konsekvenser för yrkesverksamma inomområdet mental hälsa, I.T., online dejtingföretag och dejting platform-användare iochmed attanvändare nu får en större förståelse för vilken innebörd användandet av dejtingappar somtillhör dessa två klasser har.

<p>Syftet med den här studien var att ur ett lärarperspektiv synliggöra problematiken med att få till stånd ett gemensamt synsätt vad gäller barns utveckling, kunskap och lärande mellan lärare i förskoleklassen och grunskolans år ett. Frågeställningen var: Vilka faktorer anser lärare främjar respektive hindrar utvecklingen av ett gemensamt synsätt?</p><p>Studien var kvaltitativ och genomfördes med hjälp av inspelade intervjuer av sex lärare varav tre är verksamma i förskoleklass och de andra tre i årskurs ett.</p><p>I studiens resultat framkom en mängd faktorer som anses utgöra hinder och/eller möjligheter för att främja en gemensam syn. Det mest primära var att lärarna i arbetslaget för en dialog om verksamheten. Andra viktiga faktorer var till exempel arbetslagets sammansättning, samt att tid avsätts för att kunna föra diskussioner kring barnen, deras kunskap och utveckling. Det visade sig också att det inte räcker med att en faktor uppfylls- om exempelvis tid finns men viljan till smatal inte finns nås inget resultat i sig. Det visade sig att den ena faktorn inte utesluter den andra, samt att de faktorer som ses som hinder även kan framsrå som möjligheter.</p> / <p>The purpose of this study is to present the complexity of creating a shared platform around the work among teachers in pre-school and the first year of school concerning promoting the children´s development, knowledge and learning.

Στόχος της παρούσας Διπλωματικής Εργασίας είναι ο σχεδιασμός και υλοποίηση ενός Κρυπτογραφικού Συστήματος με βάση τον Αλγόριθμο κατακερματισμού JH. Ο σχεδιασμός του κρυπτογραφικού αυτού συστήματος έγινε με τη χρήση γλώσσας VHDL (Very High Speed Integrated Circuits hardware description language) και στη συνέχεια η υλοποίηση αυτή έγινε πάνω σε πλατφόρμα FPGA (Field Programmable Gate Array). Ο αλγόριθμος JH είναι ένας αλγόριθμος κατακερματισμού (hash function) ο οποίος σχεδιάστηκε στα πλαίσια του διαγωνισμου κρυπτογραφιας NIST (National Institute of Standards and Technology). Η πρώτη του έκδοση έγινε στις 31 Οκτωβρίου 2008 ενώ η τελική του έκδοση έγινε στις 16 Ιανουαρίου 2011. Ο Αλγόριθμος JH έχει τρεις υποκατηγορίες. Υπάρχει ο JH-224, JH-256, JH-384 και ο JH-512. Βασικό χαρακτηριστικό του αλγορίθμου αυτού είναι το γεγονός πώς οι λειτουργίες που συμβαίνουν σε κάθε γύρο είναι ίδιες. Επίσης σημαντικό γνώρισμα ειναι η ασφάλεια που παρέχει ο αλγόριθμος αυτός καθώς ο μεγάλος αριθμός των ενεργών S-boxes που χρησιμοποιούνται και ταυτόχρονα το γεγονός ότι σε κάθε γύρο χρησιμοποιείται ένα διαφορετικό κλειδι το οποίο παράγεται εκεινη τη στιγμή και δεν ειναι αποθηκευμένο σε ένα σημείο, στο οποίο θα μπορούσε κάποιος να επέμβει, κάνει το σύστημά μας εξαιρετικά δυνατό και ανθεκτικό απέναντι σε επιθέσεις όπως είναι η διαφορική κρυπτανάλυση. Για την εξακρίβωση της ορθής λειτουργίας του συστήματος χρησιμοποιήθηκε μία υλοποίηση του Αλγορίθμου JH σε γλώσσα C. Χρησιμοποιώντας την υλοποίηση αυτή κάθε φορά που θέλουμε να κρυπτογραφήσουμε ένα μήνυμα το οποίο είναι μία σειρά από bit, λαμβάνουμε το κρυπτογραφημένο μήνυμα. Αυτο το κρυπτογραφημένο μήνυμα το συγκρίνουμε με αυτό που παίρνουμε στην έξοδο του συστήματος JH που σχεδιάσαμε και με αυτό το τρόπο επιβεβαιώνουμε την ορθότητα του αποτελέσματος. Ύστερα από την non-pipelined υλοποίηση του συστήματος αυτού, χρησιμοποιήθηκε η τεχνική της συσωλήνωσης (pipeline). Πιο συγκεκριμένα εγιναν 4 διαφορετικές pipelined υλοποιήσεις με 2,3,6 και 7 στάδια. Σκοπός είναι για κάθε μία pipelined υλοποίηση να γίνει έλεγχος σε θέματα απόδοσης, κατανάλωσης ισχύος καθώς επίσης και σε θέματα επιφάνειας. Στη συνέχεια γίνεται μία σύγκριση στα προαναφερθέντα θέματα μεταξύ των διαφορετικών pipelined υλοποιήσεων και με την non-pipelined υλοποίηση του κρυπτογραφικού συστήματος JH. Επίσης αξίζει να σημειωθεί πώς γίνεται ιδιαίτερη αναφορά στο throughput και στο throughput per area των pipelined υλοποιήσεων. Από τα πειραματικά αποτελέσματα που προέκυψαν η JH NON PIPELINED υλοποίηση έχει απόδοση 97 MHz με κατανάλωση ισχύος 137mW και συνολική επιφάνεια 2284 slices σε SPARTAN 3E FPGA συσκευή. Ενώ από την ανάλυση της JH NON PIPELINED υλοποίησης και των 4 pipelined υλοποιήσεων σε 4 διαφορετικά FPGA (2 της οικογένειας SPARTAN και 2 της οικογένειας VIRTEX) συμπεραίνουμε πώς στην οικογένεια VIRTEX η κατανάλωση ισχύος είναι πάντα μεγαλύτερη σε σχεση με την οικογένεια SPARTAN. / The purpose of this Thesis Project is the design and implementation of a Cryptographic System using the JH Hash Algorithm. The design of this Cryptographic System was performed using the VHDL language (Very High Speed Integrated Circuits hardware description language) and then this implementation was executed on a FPGA platform (Field Programmable Gate Array).The JH Algorithm is a hash algorithm that was developed during the NIST (National Institute of Standards and Technology) Cryptography Competition. Its first version was released on 31 October 2008 while its last version was released on 16 January 2011. The JH Hash Algorithm has three subcategories. There is JH-224, JH-256, JH-384, and JH-512. Basic characteristic of this Algorithm is the fact that the functions that are executed in each round are identical. Moreover important characteristic is the security that this Algorithm provides us while the big number of active S-Boxes that is used and in the same time the fact that in each round a different key is produced on the fly, and is not stored in a place that a third person could have access, makes our system really strong and resistant to attacks such as the differential attack. To confirm the right functionality of the system the implementation of the JH Algorithm in C Language is used. Using this implementation each time we want to cipher a message, which is a sequence of bits, we get the message digest. This message digest is compared with the message digest that we get from the JH system that we developed with VHDL and in this way we confirm the correctness of the result. After the non pipelined implementation of the JH system the pipeline technique was used. To be more specific 4 different pipelined implementations with 2, 3, 6 and 7 stages were performed. The target was to check the performance, area and power dissipation for each pipelined implementation. Next a comparison was performed between the various pipelined implementations and the non pipelined implementation for the above mentioned issues. In addition to this it is worth to mention that considerable reference is made for throughput and throughput per area for the pipelined implementations. According to the experimental results the JH NON PIPELINED implementation has a performance of 97 MHz, with power dissipation of 137mW and a total area of 2284 Slices on SPARTAN 3E FPGA device. From the JH NON PIPELINED implementation and the other 4 pipelined implementations on 4 different FPGA Devices (2 from the VIRTEX family and 2 from the SPARTAN family) we concluded that the power dissipation is bigger in VIRTEX family devices in comparison to SPARTAN family Devices.

One of the most important events in the history of life is the evolution of the complex, eukaryotic cell. The eukaryotes are complex organisms with membrane-bound intracellular structures, and they include a variety of both single-celled and multicellular organisms: plants, animals, fungi and various protists. The evolutionary origin of this group may be studied by direct evidence of past life: fossils. The oldest traces of eukaryotes have appeared by 2.4 billion years ago (Ga), and have additionally diversified in the period around 1.8 Ga. The Mesoproterozoic Era (1.6-1 Ga) is characterised by the first evidence of the appearance complex unicellular microfossils, as well as innovative morphologies, and the evolution of sexual reproduction and multicellularity. For a better understanding of the early eukaryotic evolution and diversification patterns, a part of this thesis has focused on the microfossil records from various time periods and geographic locations. Examination of microfossil morphology, cell wall microstructure and biochemical properties, reflect their intracellular complexity and function, and allow reconstructions of their life cycle, as well as observing the evolutionary pattern of change from Mesoproterozoic, to Cambrian-Ordovician transition. Several case studies included assemblages deriving from Mesoproterozoic, Neoproterozoic and early Paleozoic time intervals that show disparate morphotypes and innovative features indicative of algal clades. The Mesoproterozoic Ruyang Group in northern China has yielded a diverse microfossil assemblage that provides important clues about the diversification of different eukaryotic groups. Furthermore these microfossils contributed an additional evidence for the emergence of the crown group Eukarya by 1.7-1.4 Ga. In another part of this thesis, examination of wall microstructure and chemical properties via Raman spectroscopy has been used to assess the biological affinities of various Neoproterozoic problematic carbonaceous compression fossils. Studies on the early Phanerozoic (c. 545-485 Ma) assemblages from Estonia reconstructed patterns of the early radiations of phytoplankton and its evolutionary innovations. A continuing theme in this thesis has been using a combination of evidence of microfossils’ fine-scale morphology, ecology and chemical properties to determine their function in life, in addition to their systematic position. / Palaeobiology and diversification of Proterozoic-Cambrian photosynthetic eukaryotes

No. of bitstreams: 1 DissMSOM.pdf: 2216662 bytes, checksum: 491d51f338496c8de2f29f3447d09b5b (MD5) Previous issue date: 2015-08-14 / Open institutional repositories (IR) have became a major instrument for providing open access to global scientific production. In addition to providing scientific documents, IR can be used to fulfill institutional interests of the institution, such as promoting the storage of documentation, preserving institutional memory and also bringing worldwide exposure to its production. The implementation of an IR, however, depends on a number of activities, where one of the major challenges is populating it with data. In order to find solutions to improve the process of populating an IR, the aim of this work was to develop a system to automatically extract metadata from the Lattes Platform, inserting this metadata in a reference database, regarded as an intermediate step for populating the IR. Besides easing the submission process, the reference base will be able to support effective marketing campaigns to foster the auto-archival of scientific works. Our approach consists of a qualitative research, developed through action research, within the Federal University of São Carlos – UFSCar. The achieved results comprised the development of a collection of automated solutions essential for gathering and handling metadata to be imported by DSpace. The solution here proposed can be implemented by any institution, with or without an IR, strongly contributing to maximize scientific communication by automating part of the process of implementing and maintaining institutional repositories. / Os repositórios institucionais abertos (RI) tornaram-se um dos principais instrumentos para o acesso aberto à produção científica global. Além da disponibilização de documentos científicos, os RI podem ser utilizados para os diversos interesses da instituição, promovendo armazenamento de suas documentações, preservação da memória institucional e também dando visibilidade mundial para sua produção. A implementação de um RI, no entanto, envolve uma série de ações, onde um dos grandes desafios é o seu povoamento. Visando contribuir para uma solução que minimize o esforço humano necessário para o povoamento do repositório, o objetivo geral deste trabalho foi desenvolver uma sistemática automatizada de extração de metadados provenientes da Plataforma Lattes realizando a inclusão dos dados em uma base referencial, considerada uma etapa intermediária no processo de povoamento do RI. Além de facilitar o processo de submissão, a base referencial poderá amparar efetivas políticas de divulgação e de incentivo ao autodepósito da produção científica. Trata-se de uma pesquisa de natureza qualitativa, desenvolvida por meio de pesquisa-ação, tendo como unidade-caso a Universidade Federal de São Carlos – UFSCar. Os resultados alcançados compreenderam o desenvolvimento de um conjunto de soluções automatizadas, necessárias à coleta, tratamento e importação dos metadados pela ferramenta DSpace. A solução de povoamento aqui proposta poderá ser implementada em qualquer outra instituição que possua ou não um RI, contribuindo fortemente para a maximização da comunicação científica ao automatizar parte do processo de implementação e manutenção de repositórios institucionais.

Sachsen bekommt eine neue Videoplattform – den Videocampus Sachsen (VCS). Durch das Sächsische Ministerium für Wissenschaft und Kunst (SMWK) wurde Ende 2017 das Projekt zur Umsetzung genehmigt. Im Rahmen der Pilotphase 2018 erfolgt die Konstituierung eines sächsischen Verbundes wie auch die An- und Einpassung der Plattform in die gemeinsame technische Infrastruktur der sächsischen Hochschulen. Ab 2019 soll das Videoportal dann durch den Dienstleister BPS GmbH in den Regelbetrieb überführt werden. Bis hierhin war es ein langer Weg. Der vorliegende Sammelband dokumentiert die Schritte dorthin. Auf den folgenden Seiten werden zentrale Ergebnisse der 2015/16 erstellten, kumulativen Machbarkeitsuntersuchung zur Einrichtung eines hochschulübergreifenden sächsischen Videoportals vorgestellt.

Compreender a espacialidade dos fenômenos estudados, no presente e no passado, e compará-lo por meio de suas sobreposições, é algo que a própria Geografia busca fazer, e compreender e utilizar a linguagem cartográfica, ampliando as possibilidades dos alunos de analisar informações em vários campos do conhecimento, além de contribuir para a estruturação de uma noção espacial. O objetivo desse projeto foi de aplicar as possibilidades de uso de geotecnologias como incentivo para o ensino da geografia na EEEFM Plínio Lemos, do município de Puxinanã – PB, buscando verificar a visão temporal dos educandos a cerca de seu meio ambiente e as modificações ao longo do tempo. Foi aplicado um questionário nas turmas do 3º Ano médio, turno manhã, onde 50% afirmaram saber o que são geotecnologias e que têm acesso a softwares do gênero (Google Earth, Wikimapia e GPS-Sistema de Posicionamento Global), 73,8% disseram não terem sentido dificuldade em responder o questionário, no entanto, o tempo usado para responder o mesmo bem como as vezes em que os aplicadores do questionário foram chamados para tirar dúvidas mostram o contrário. É importante destacar que 85,7% dos alunos afirmaram que nunca tinham ouvido falar esse termo por parte do professor da disciplina. / Information technology is increasingly present in school life, either via the Internet or other multimedia.

And it was possible to observe favorable results to the proposed method, which demonstrates effectiveness of the protocol, object of this reasearch.

Notre thèse a pour point de départ une situation de management empirique représentée par un Cercle de réflexions prospectives, que nous appelons PSP (Prospective Stratégique Participative), menée par BASF Agro sur une période de plus de dix ans avec l’ensemble des acteurs de la filière agro-alimentaire. Les acteurs du Cercle ont une relation marchande et décident d’explorer des opportunités de collaboration sur un mode communautaire. Ils expandent ensemble un espace de conception où interagissent les savoirs et les relations dans un processus d’innovation. Nous aboutissons à l’hypothèse que la PSP joue le rôle d’une plateforme ouverte de fabrique de la stratégie (open strategizing platform) et de fonctionnement des affaires entre les acteurs qui sert à réfléchir et concevoir ensemble des stratégies nouvelles. La PSP est un dispositif de gestion dont la vision simplifiée de l’organisation (la configuration de référence implicite) est un écosystème d’affaires, et pas seulement une organisation classique. Notre analyse est basée sur une étude de cas longitudinale de dix-sept ans / Our thesis has to point of departure a situation of empirical management represented by a circle of foresight thinking, which we call FPS (Foresight Participatory Strategic), conducted by BASF Agro over a period of more than ten years with all the actors involved in the food chain. The players in the circle have a merchant relationship and decide to explore opportunities for collaboration on a community way. They expanded together a design space or interact the knowledge and relationships in a process of innovation. We have ended up with the assumption that the FPS plays the role of an open-strategizing platform and for the operation of business between the actors which is used to reflect and devise all the new strategies. The FPS is a management innovation which the configuration of implicit reference is a business ecosystem, and not just a typical organization. Our analysis is based on a longitudinal case study of seventeen years
