No. of bitstreams: 1 marinaivanovpereirajosue.pdf: 1327137 bytes, checksum: 2b404732ed5a5dd800a9c7adb3194f8f (MD5) Previous issue date: 2016-06-30 / Atualmente o conteúdo hipermídia pode ser entregue utilizando diferentes tecnologias de rede, como a TV Digital terrestre por satélite, IPTV e Web. Por isso, as máquinas de apresentação hipermídia devem levar em conta as especificidades dessas redes suportadas, de modo a prover os níveis de QoS/QoE esperados pelo usuário do conteúdo. Máquinas de apresentação avançadas podem empregar também a análise de conteúdo para auxiliar na tarefa de manutenção dos níveis de QoE. De modo especial, quando o conteúdo hipermídia inclui dados enviados por pull, as máquinas de apresentação podem criar um Plano de Pré- Busca baseado no comportamento da apresentação extraído da especificação do conteúdo. Entretanto, quando o conteúdo hipermídia inclui dados enviados por push, a análise do conteúdo deve ser transferida para o lado do servidor e se basear na construção de um Plano de Transmissão de Conteúdo. O Plano de Transmissão de Conteúdo é uma estrutura de dados que prevê os instantes em que objetos de mídia devem ser transmitidos, e por quanto tempo, para otimizar o uso de recursos fim-a-fim como largura de banda e espaço de armazenamento nos receptores. Este trabalho propõe um framework para gerenciamento da entrega de conteúdo hipermídia em modo push. O framework é genérico o suficiente para ser adaptável a diferentes cenários de entrega de conteúdo que podem empregar diferentes protocolos e técnicas de gerenciamento. Alguns cenários de instanciação do framework e seus respectivos resultados são discutidos nesta dissertação. / Nowadays hypermedia content may be delivered using different networking technolo- gies, such as terrestrial broadcasting, satellite, IPTV and the Web. Therefore hypermedia presentation engines must be designed taking into consideration the specificities of their supported networks, in order to provide the expected QoS/QoE levels. Advanced pre sentation engines should also employ hypermedia content analysis to help on the task of maintaining QoE levels. Specifically, when the hypermedia content includes pulled data, presentation engines may create a Content Prefetching Plan based on the presentation behavior learned from the specification of that content. However, when the hypermedia content includes pushed data, this content analysis should be transferred to the server side and be taken as a basis for building the so-called Content Transmission Plan. The Content Transmission Plan is a data structure that predicts the time when media objects should start to be transmitted and for how long, in order to optimize end-to-end resource usage such as communication bandwidth and storage space in receivers. This work pro poses a framework for managing the push-mode delivery of hypermedia content. The framework is generic enough to be instantiated over different content delivery scenarios that may employ different protocols and management techniques. Several instantiation scenarios and their respective results are also discussed in this dissertation.

Idag lever vi i ett samhälle där smartphones blivit allmänt förekommande. Som en följd av ökade nätverkshastigheter har möjligheterna att enkelt få tillgång till information aldrig varit bättre. Den ökade användning av smartphones har också skapat möjligheter till en rad olika applikationer såsom platsbaserade applikationer som använder sig av pushtjänster.  I vår studie har vi undersökt frågan “Hur kan platsbaserade pushtjänster som ett verktyg för direktmarknadsföring designas för att möta smartphoneanvändares behov?”. Genom en litteraturstudie har vi sammanställt och identifierat designteman från tidigare HCI- och interaktionsdesign forskning. Vår litteraturstudie resulterade i de fem designteman, Användarkontroll, Flexibilitet, Visibilitet, Personlig integritet och Felhantering. Dessa teman har vi sedan utvärderat genom att skapa en prototyp som vi testar mot användare.  Resultatet av studien är en uppsättning designriktlinjer inom fyra designteman för hur platsbaserade pushtjänster ska designas för att möta smartphoneanvändares behov. / We live in a world were smartphones are becoming increasingly ubiquitous. As a result of increased network speeds the possibilities to easily access information have never been greater. The increase in smartphone use has also created an increase in opportunities to create a range of applications such as location based applications that make use of push services. In our study, we have researched “How location-based push services as a tool for direct marketing can be designed to meet smartphone users’ needs? “. Through a literary review, we have compiled and identified design themes from previous HCI and interaction design research. The review resulted in the five design themes, User control, Flexibility, Visibility, Privacy and Error Handling. We assessed the themes by creating a prototype that we tested with users. The result of the study is a set of design guidelines within four design themes for how location-based push services should be designed to meet smartphone users’ needs.

Ce travail de recherche a comme objectif la révision de la logique de la sexuation dans la clinique psychanalytique contemporaine. La thèse freudienne du « primat de phallus », reprise par Lacan d’abord dans sa logique sexuée « être ou avoir », gardera toute son importance dans son tableau de la sexuation, présentée dans le séminaire Encore. Ce tableau de la sexuation, référé au phallus comme au seul et unique signifiant de la différence des sexes, nous laisse “déboussolé” dans la recherche des particularités des modes contemporains d’être sexué. Par contre, nous affirmons que la thèse de Lacan selon laquelle « l’être sexué ne s’autorise que de lui-même […] et quelques autres » trouve toute sa pertinence quant au devenir sexué du sujet contemporain et se met au premier plan dans le tout dernier enseignement de Lacan à travers son étude du parlêtre en terme de nouage et de suppléance. Nous avons ciblé la clinique du pousse-à-la-femme et des femmes-transsexuelles afin de montrer, que la psychanalyse, orientée par le dernier enseignement de Lacan, permet de reconsidérer ces deux cliniques de troubles d’identité sexuelle comme des modes de s’autoriser en tant que sexués. A travers nos cas cliniques, nous prétendons avoir démontré que pour ces sujets, faute de se servir du signifiant phallique « pour tous », il s’agit néanmoins de tentatives pour trouver leur manière sinthomatique de rejoindre dans leur quête identitaire le discours sexuel commun qui soutient pour l’instant la binarité des sexes. / This study aims at a revision of the sexuation logic within the modern psychoanalytical clinic. The Freudian thesis on the "primacy of phallus" was initially assumed by Lacan as a sexuated logic "to be or to have" a phallus, and it kept its importance in his later works, it was especially developed in his XX Seminar "Encore" in the table of sexuation. We have demonstrated that as far as the table of sexuation refers to the phallus, described in terms of the phallic function, that continues to be the only signifier of the difference between the sexes, we can hardly apply it to studying some of the particularities of the modern modes of sexuation. On the contrary we suggest that Lacan’s thesis that "the sexuated being is authorized only by himself [...] and by some others" remains valid as far as the becoming of the modern subject is concerned and it is brought to the forefront in the last teaching of Lacan through his study of the "talking being" in terms of knotting and suppliances. Therefore we have chosen the study of the the clinic of the push-to-be-the-woman and that of transsexual women in order to demonstrate that psychoanalysis oriented by the last teaching of Lacan gives us the possibility to reconsider these two clinics of sexual identity disorders in terms of modes of auto-authorization as sexuated. Via our clinical cases we suggest that these subjects left out of the possibility to appeal to the phallic signifiers "for everybody", try nevertheless to find their sintomatic way to join the common sexual discourse without the reference of the sexual binaries.

Abstract The main task for most development-intensive organisations is to create, develop and commercialise new products and services. The technology push (TP) concept is considered an important competitive advantage for companies trying to create breakthrough products. Because development processes are risky and failure rates are high, especially in the case of technology pushed projects, defined success factors are valuable knowledge for the management of development-intensive firms. The prime objective of this study is to present a compact set of TP project success factors in an information and communication technology (ICT) context. Because the literature on new product development and innovation has presented many success factors for developed products, but has done so in a way that presents the factors as having a nebulous nature, the specification of TP success factors is also presented. The success factors are also empirically validated. The goal of the validation was to determine the relevance of the success factors introduced, and potentially define new ones. The validation was performed through an empirical study with semi-structured company interviews. As a result of this study we concluded that one success factor defined through the literature review should be removed due to a lack of relevance, that the other twelve success factors were validated, and three new success factors were identified during the empirical study. Eventually fifteen TP success factors are defined and presented. The practical relevance of this study is to help firm management to recognise the real actions needed to reduce product development risks. The theoretical relevance is in helping scholars to focus on key issues when studying the key factors of breakthrough development cases. / Tiivistelmä Tuotekehitystä harjoittavien yritysten päätehtävänä on luoda, kehittää ja kaupallistaa uusia tuotteita ja palveluita. Yritysten pyrkiessä luomaan läpimurtotuotteita, ”Technology push” -konseptia pidetään niille tärkeänä kilpailuetuna. Koska tuotekehitysprosessit ovat riskialttiita ja epäonnistumisen mahdollisuudet suuret erityisesti teknologiatyöntöisillä projekteilla, tarkasti määritellyt menestystekijät ovat arvokasta tietoa yritysten johdolle. Tämän työn päätarkoituksena on esitellä yhtenäinen ja tiivis joukko teknologiatyöntöisten projektien menestystekijöitä ICT toimialalla. Uusien tuotteiden kehittämistä ja innovaatioita käsittelevä lähdekirjallisuus esittelee lukuisia menestystekijöitä. Ne on kuitenkin esitelty vaikeasti selitettävällä tai monimerkityksellisellä tavalla, joten olemme esittäneet myös niiden tarkat määrittelyt. Menestystekijät ovat validoitu myös empiirisesti. Validoinnin tarkoituksena oli löytää esiteltyjen menestystekijöiden relevanssi ja löytää mahdollisesti uusia menestystekijöitä. Validointi toteutettiin puolistrukturoiduilla yrityshaastatteluilla. Työn tuloksena esitetään kirjallisuuskatsauksen ja empiirisen validoinnin avulla määritellyt 15 teknologiatyöntöisten projektien menestystekijää. Tutkimuksen käytännöllinen merkitys on auttaa yritysjohtoa tunnistamaan tärkeät toiminnot tuotekehitysriskien madaltamiseksi. Tutkimuksen teoreettinen merkitys on auttaa tutkijoita keskittymään avainasioihin ja tunnistamaan menestystekijät läpimurtotuotetutkimuksessa.

Almost all cell-phones and camcorders sold today are equipped with a CMOS (Complementary Metal Oxide Semiconductor) image sensor and there is also a general trend to incorporate CMOS sensors in other types of cameras. The sensor has many advantages over the more conventional CCD (Charge-Coupled Device) sensor such as lower power consumption, cheaper manufacturing and the potential for on-chip processing. Almost all CMOS sensors make use of what is called a rolling shutter. Compared to a global shutter, which images all the pixels at the same time, a rolling-shutter camera exposes the image row-by-row. This leads to geometric distortions in the image when either the camera or the objects in the scene are moving. The recorded videos and images will look wobbly (jello effect), skewed or otherwise strange and this is often not desirable. In addition, many computer vision algorithms assume that the camera used has a global shutter, and will break down if the distortions are too severe. In airborne remote sensing it is common to use push-broom sensors. These sensors exhibit a similar kind of distortion as a rolling-shutter camera, due to the motion of the aircraft. If the acquired images are to be matched with maps or other images, then the distortions need to be suppressed. The main contributions in this thesis are the development of the three dimensional models for rolling-shutter distortion correction. Previous attempts modelled the distortions as taking place in the image plane, and we have shown that our techniques give better results for hand-held camera motions. The basic idea is to estimate the camera motion, not only between frames, but also the motion during frame capture. The motion can be estimated using inter-frame image correspondences and with these a non-linear optimisation problem can be formulated and solved. All rows in the rolling-shutter image are imaged at different times, and when the motion is known, each row can be transformed to the rectified position. In addition to rolling-shutter distortions, hand-held footage often has shaky camera motion. It has been shown how to do efficient video stabilisation, in combination with the rectification, using rotation smoothing. In the thesis it has been explored how to use similar techniques as for the rolling-shutter case in order to correct push-broom images, and also how to rectify 3D point clouds from e.g. the Kinect depth sensor. / VGS

Depuis les années 60, la génération d’acide fort de Brönsted par un processus photoinduit à un photon est utilisée dans des nombreux domaines de recherche de plus en plus nombreux. Cependant, de tels acides peuvent-être facilement obtenus par voie biphotonique ce qui présente de nombreux avantages comme par exemple : une meilleure réactivité via une excitation direct du photoacide, l’utilisation possible d’une atmosphère non contrôlée, l’utilisation de microlasers à impulsions sub-nanosecondes peu couteux, mais aussi l’augmentation de la résolution spatiale des micro-objets 3D fabriqués. La génération d’acide se fait généralement par transfert d’électron entre un sensibilisateur et un générateur de photoacide (PAG). Une approche prometteuse consiste à associer, sur une même molécule, un PAG et un chromophore actif à deux photons. Il a donc semblé intéressant de développer de nouveaux PAG capables, par excitation biphotonique, d’amorcer directement la photopolymérisation. Nous avons choisi de préparer des systèmes capto-datifs stilbéniques, de nature neutre ou ionique. Aussi, une série de PAG neutres substitués par des groupements diphénylamino- donneur et iminosulfonates -cyanés accepteurs a été synthétisée. Nous avons également commencé, mais non achevé, la synthèse de PAG neutres portant des groupements iminosulfonates -trifluorométhylés. Puis, nous avons cherché à synthétiser des PAG ioniques substitués soit par un groupement éthoxy soit par un groupement diphénylamino soit par un groupement julolidine. Néanmoins, la dernière étape de la synthèse est pour l’instant un verrou synthétique. / Since the 60’s, the generation of strong Brönsted acids by a one-proton photoinduced process has been used in more and more research areas. Recently, it has been shown, that such acids are easily obtained by a two-photon process. This offers many advantages such as: i) a better reactivity owing to a direct excitation of the photoacid, ii) the possible use of a non-controlled atmosphere, iii) the use of inexpensive microlasers with sub-nanosecond impulsions, iv) the increase of spatial resolution in 3D microfabrication. The acid generation generally proceeds through a photo-induced electro transfer from an excited sensitizer to the photoacid generator (PAG). A promising approach should be the introduction on a single molecule of both a PAG and a two-photon active chromophore moiety. In this context, we have developed new PAGs able to initiate photopolymerisation through a two-photon activation process. The syntheses were focused on stilbenic push-pull systems having either a neutral or an ionic nature. A series of neutral PAGs bearing a diphenylamino donor group and an α-cyano iminosulfonate acceptor moiety has been synthesized. The preparation of neutral PAGs bearing iminosulfonate α-trifluoromethylated groups were not yet completed. The syntheses of ionic PAGs substituted by an ethoxy group, a diphenylamino group or a julolidine one, could not be completed either.

This research aims to analyze an asylum seeker's choice of asylum country and why Sweden inparticular. The study is based on Professor Lee's (1966) push- and pulltheory and the questionson which the study is based are "what impact do push and pull factors have on the choice ofrecipient country?" and "are there differences between asylum seekers from Syria andAfghanistan when choosing a recipient country?" The method used is an interview study, morespecifically semi-structured interviews. The conclusions found in the study are that the resultsof this study and previous studies are consistent, the main pullfactors that are consistent withthe theory and that explain the reason why Sweden is chosen, are the possibility of educationand work, a relative or friend who already lives in Sweden, human rights and that Sweden isconsidered a safe country. The respondents' pushfactor which explains the reason for leavingthe country of origin, was first and foremost that everyone needed to flee due to war and misery.It does not matter where an asylum seeker comes from as everyone has the same goal and thatis to survive.

This research aims to gain a detailed understanding of the push and pull factors that lead many Syrians in Turkey to migrate to Europe. Syrians are pushed to migrate for various reasons, including socio-economic difficulties in Turkey. It explores the Syrians’ experiences in Turkey and the elements that have deterred them from gaining the fundamental rights of accommodation, access to the labor market, and refugee status. The pull factors refer to the gains that the Syrians might achieve when migrating to Europe. These gains are socio-economic gains that assure a better future for them in Europe in comparison to their presence in Turkey. In this case, this research also explores how the Syrians plan to migrate to Europe by employing the influence of their social networks to conduct their secondary migration. This qualitative study uses seven semi-structured interviews and analyzes the experiences of the interviewees in order to reach concrete conclusions. The results of this study, according to the interviewees’ experiences, show that restrictive Turkish policies and procedures have pushed many Syrians to migrate. At the same time, the Syrians are attracted to migrating to Europe for better protection for them and their children. The findings also demonstrate that social ties influenced Syrians in their decision to migrate to Europe and avoid being deported to Syria.
