Full textAbstract:
Materials requirements planning (MRP) is a widely used method for production planning and scheduling. Planned lead-time (PLT) and lot size are two of the input parameters for MRP systems, which determine planned order release dates. Presently, planned lead-time and lot size are estimated using independent methodologies. No existing PLT estimation methods consider factors such as machine breakdown, scrap-rate, etc. Moreover, they do not consider the capacity of a shop, which changes dynamically, because the available capacity at any given time is determined by the loading of the shop at that time. The absence of such factors in calculations leads to a huge lead-time difference between the actual lead-time and PLT, i.e., lead-time error. Altering the size of a lot will have an effect not only on the lead-time of that lot but also on that of other lots. The estimation of lot size and lead-time using independent methodologies currently does not completely capture the inter-dependent nature of lead-time and lot size.
In this research, a lot-sizing model is modified in such a way that it minimizes the combination of setup cost, holding cost and work-in-process cost. This proposed approach embeds an optimization routine, which is based on dynamic programming on a manufacturing system model, which is based on open queuing network theory. Then, it optimizes lot size by using realistic estimates of WIP and the lead-time of different lots simultaneously for single-product, single-level bills of material. Experiments are conducted to compare the performance of the production plans generated by applying both conventional and the proposed methods. The results show that the proposed method has great potential and it can save up to 38% of total cost and minimize lead-time error up to 72%.Master of Science

Desse complexo conjunto de seres imprevisíveis, há um caso particular de uma personagem secundária. Figuraaparentemente dentro da narrativa como um ser anedótico, apenas para compor um ambiente cômico, pueril dentro de Combray, a cidadezinha prosaica de infância do herói do romance: a tia Léonie. O objetivo do trabalho que apresentamos não é somente analisar esse ser aparentemente risório, a eterna doente de Combray. Sobretudo, pretende-se mostrar dentro dopróprio romance proustiano que Léonie, como os tantos personagens desse trajeto rumo à descoberta da verdadeira vocação do herói, também colocará sua pequena pedra na composição monumental da obra por vir, pois, ao seu modo, também contribuirá para a composição daquele que renunciará à vida, se reservando apenas o essencial, para compor seu romance.IN THE NOVEL OF MARCEL PROUST\'S \"In Search of Lost Time\", parade before the reader\'s eyes, a compendium of enigmatic, fragmentary beings, offering itself, throughout the work, a range of new images and possibilities.

The objective of the present work is not only to analyze this seemingly be risorius, \"the eternal sick of Combray.\" Above all, it presents in the Proustian novel itself that Léonie, as so many characters that path towards the discovery of the true vocation of the hero, also put your little stone in monumental composition of the work to come, for, in his own way, also contribute for the composition that he would resign to life, reserve to itself only the essentials, in order to compose his novel.

Full textAbstract:
Pesquisa de teoria literária sobre o romance Em busca do tempo perdido, de Marcel Proust. Tem como objetivo refletir sobre a unidade do romance Em busca do tempo perdido, por meio de uma análise da personagem de Charles Swann. Este trabalho principia pelo levantamento do projeto global do ciclo romanesco, a partir de um trecho d´A Prisioneira em que o narrador-protagonista estabelece dois tipos de unidade para a obra de arte: uma lógica e outra vital. O segundo capítulo expõe as dificuldades que esse projeto coloca: como criar uma obra artística que seja viva e aberta, ao mesmo tempo que coesa e íntegra? A resposta é encontrada nos vasos comunicantes, nas transversalidades capazes de dar ao ciclo romanesco, não uma unidade lógica, mas vital. O terceiro capítulo analisa um dos nós, um dos pontos para o qual convergem essas transversalidades: a personagem de Charles Swann. Por meio da reconstituição desta personagem, são discutidos aqui alguns temas importantes para o romance: a formação do artista, assim como a relação entre a arte e a vida. Vemos em seguida que, em contraponto a Swann, cuja trajetória é vista como uma vocação artística frustrada, a expressão do romance proustiano busca condensar as experiências de um indivíduo para se tornar escritor. Finalmente, o excerto reflete sobre o caráter realista do romance: tendo por base um ensaio de Antonio Candido, \"Realismo (via Marcel Proust)\", e levando em conta um acontecimento-chave para o escritor francês, analisamos aqui o papel desempenhado pelo caso Dreyfus na narrativa. A hipótese mais geral desta pesquisa é a de que certos temas, representados pela personagem do diletante Charles Swann e por seu engajamento no caso Dreyfus, tornam difícil o acabamento do romance e lhe dão uma forma crítica, polêmica, viva. Esta não retira sua unidade da perspectiva de um artista profissional, cujo ofício participa da divisão do trabalho e do conhecimento de nossa sociedade; mas vincula-se à percepção de um diletante, cujo ponto de vista conserva algo de maravilhoso e mágico para as criações artísticas, como se a arte oferecesse mais do que obras e fosse capaz de ensinar a ler a vida. Lembramos neste sentido que a narrativa proustiana, desde seu começo até seu final, acompanha o ponto de vista não de um artista formado, mas de um apaixonado pelo universo artístico: o protagonista que deseja criar uma obra de arte e a imagina capaz de organizar a vida à imagem de sua complexidade.A literary theory research on Marcel Proust´s novel In Search of Lost Time. The objective is to discuss the unity of Proust´s novel through an analysis of Charles Swann´s character. The first chapter of this work is a survey of the novel\'s global project, taking a passage of The Captive as a starting point, where the novel\'s narrator identifies two kinds of unity for the work of art, a logical one and a vital one. We remind then some difficulties that this project brings along with it: how can we create a work of art which is open and live, as well as coherent and complete? The answer is found in the communicant vases, in the transversalities able to provide the novel with a vital unity, not a logical one. In the third chapter, we analyse one of the points into which these transversalities converge: Charles Swann´s character. By a reconstitution of this character, we discuss certain important motifs of Proust´s novel: the education of the artist, as well as the relationship between art and life. In comparison with Swann, who represents a frustrated artist, we recognize that Proust´s literary expression seeks to condense someone\'s experiences to become a writer in the actual society. Finally, in the last part, we study the realistic aspects of the novel, based on Candido´s essay, \"Realism (according to Proust)\", and, taking into account an important political experience for the writer, we review the role of Dreyfus\'s Affair in the narrative. The general hypothesis of this research is that some themes, represented by Charles Swann´s diletantisme and his political engagement at the Affair, make it difficult to finish the novel and also give it a critical, polemical and live form. This form does not take its unity from a professional artist´s perspective, which participates in the division of the work and knowledge of our society, but from the dilettante condition, which point of view preserves something magical and wonderful for the artistic creations, as if art could give more than artworks and teach to read life. In this sense, we remind that Proust´s novel follows the point of view of a passionate for arts rather than a professional writer: the hero who wants to create a work of art and who believes it capable to organize the world at its complexity.

Embora o romance Em busca do tempo perdido seja incontestavelmente uma obra inacabada, não se trata, entretanto, de uma obra incompleta. Seu fechamento circular, promovido pelo diálogo entre o primeiro e último volumes, foi tema de grande parte da crítica proustiana. Com relação à sua composição, seu processo escritural passou por diversas mudanças e a construção, equiparada à execução de uma catedral, poderia igualmente ser caracterizada pela colagem, montagem ou costura dos fragmentos textuais esboçados nos setenta e cinco cadernos de rascunho. A busca pela unidade em meio a essa profusão de textos levou o escritor à atividade incessante de releitura e reescritura e, consequentemente, ao inacabamento da obra. O trabalho que ora apresentamos tem por objetivo o estudo dessa composição, a partir da leitura e análise dos cadernos 53 e 55, ambos consagrados à elaboração da história de Albertine.Although the novel In Search of Lost Time is certainly unfinished, it is not an incomplete work. Its round ending, promoted by the dialogue between the first and last volumes, was the subject of much Proustian criticism. With respect to its composition, its writing process has gone through many changes and the construction, equivalent to the execution of a cathedral, could also be characterized by the process of montage or the stitching of textual fragments contained in Prousts seventy-five exercise books. The search for unity amongst this profusion of texts has led the writer to the ceaseless activity of rereading and rewriting and thus to the incompleteness of the work. The analysis presented here is aimed at studying this composition, having the reading and the analysis of exercise books 53 and 55, both related to the elaboration of the story of Albertine, as a starting point.

Full textAbstract:
A dissertation submitted to Departamento de Engenharia Electrotécnica of Faculdade de Ciências e Tecnologia of Universidade Nova de Lisboa in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Engenharia Electrotécnica e de ComputadoresModern broadband wireless systems require high throughputs and can also have very high Quality-of-Service (QoS) requirements, namely small error rates and short delays. A high spectral efficiency is needed to meet these requirements. Lost packets, either due to errors or collisions, are usually discarded and need to be retransmitted, leading to performance degradation. An alternative to simple retransmission that can improve both power and spectral efficiency is to combine the signals associated to different transmission attempts. This thesis analyses two time diversity approaches to cope with lost packets that are relatively similar at physical layer but handle different packet loss causes. The first is a lowcomplexity Diversity-Combining (DC) Automatic Repeat reQuest (ARQ) scheme employed in a Time Division Multiple Access (TDMA) architecture, adapted for channels dedicated to a single user. The second is a Network-assisted Diversity Multiple Access (NDMA) scheme, which is a multi-packet detection approach able to separate multiple mobile terminals transmitting simultaneously in one slot using temporal diversity. This thesis combines these techniques with Single Carrier with Frequency Division Equalizer (SC-FDE) systems, which are widely recognized as the best candidates for the uplink of future broadband wireless systems. It proposes a new NDMA scheme capable of handling more Mobile Terminals (MTs) than the user separation capacity of the receiver. This thesis also proposes a set of analytical tools that can be used to analyse and optimize the use of these two systems. These tools are then employed to compare both approaches in terms of error rate, throughput and delay performances, and taking the implementation complexity into consideration. Finally, it is shown that both approaches represent viable solutions for future broadband wireless communications complementing each other.

La série adjectivale est une structure bien connue des lecteurs de Proust. La Recherche comprend plus de trois mille séries adjectivales ; elles combinent deux, trois, jusqu’à dix-sept adjectifs. Les variations sémantiques et syntaxiques sont nombreuses entre les séries. Devons-nous parler de série adjectivale ou de séries, au pluriel ? Quel point commun ont toutes ces séries entre elles ? Peut-on dire que la série adjectivale est une figure de style ?Notre but sera de montrer comment s’articulent ces deux phénomènes stylistiques qui font de la série adjectivale une microstructure complexe : l’effet artiste et le fait de vision. Notre thèse consiste à démontrer que la série adjectivale est un phénomène stylistique, un fait qui ne peut se comprendre qu’en analysant le fonctionnement cognitif d’une vision du monde. Dans une première partie nous analysons la série adjectivale comme un fait de langue, une syntaxe complexe ; dans une seconde partie, nous étudions les effets stylistiques produits par la série adjectivale ; puis nous démontrons que le fait syntaxique est l’expression d’un rapport phénoménologique entre le narrateur et le monde qui l’entoureAdjectival series are a well-known by Proust’s readers. We find more than three thousand adjectival series in In Search of the Lost time ; some combine two, three, four adjectives, until seveteen adjectives ; we notice semantical variations and syntactical differences. Should we speak about adjectival series or serie ? What do these series have in common ? Is the adjectival series a stylistic figure ? We want to prove that the adjectival serie is part of these two both stylistics phenomenons which are artistical writting effects and vision of the world. We analyse this stylistic fact according to psychomecanical linguistic, as the expression of an original way to feel. In the first part of research we will show that the adjectival serie is a complex syntactic fact ; in the second part we analyse the adjectival serie as a stylistic effect ; then, we demonstrate that the syntactic fact express a phenomenological link between the narrator and the world

Full textAbstract:
Following Hegel's revealing judgment concerning the ambivalence of modern morals ,it could be contented that the consensus looked for in contemporary ethical debates oscillates between utopia and nostalgia, invention and tradition. The idea of a harmonious agreement of everybody's interests that could act as a binding moral norm is usually searched for in the projection of an ideal community orin the retrieval of a lost paradise. Itis, with all the ambiguity of this expression, a quest for lost happiness. But an oscillating quest like this, inevitably faces argumentative paradoxes as the aporetical moraldebates of the last decades show, and also as this essay intends to show.Siguiendo un revelador juicio de Hegel acerca de la ambivalencia de la moral moderna, podría decirse que el consenso buscado en los debates de la ética contemporánea oscilaentre la utopía y la nostalgia, entre la invención y la tradición. La idea de una concertación armoniosa de los intereses de todos, que pueda servir de norma moral vinculante, suele buscarse en la proyección de una comunidad ideal o en la recuperación de un paraíso perdido. Es, con toda la ambigüedad de la expresión, una búsqueda de la felicidad perdida. Pero una búsqueda oscilante como ésta parece enfrentarse inevitablemente a paradojas argumentativas. como lo atestiguan los debates aporéticos de la moral en las últimas décadas, y como trata de mostrarse también en este ensayo.

Full textAbstract:
This research explores the narratives and narrative resources connected to the search for a missing parent (SMP) undertaken by people not previously recognised as searchers. Methods used are autoethnography, friendship as inquiry, writing as inquiry and fictional representations. Main research question is How do people who have searched for a missing parent create and to tell meaningful stories? What resources do they call upon? The findings identified several dominant narratives about the search for a missing parent- the narratives of search, bad place, missing piece, best interests of a child, happy ending and silence. These narratives sustain processes of marginalisation and stigmatisation of lived experience which doesn't fit in dominant narrative frameworks. This can have adverse effects on searcher, as five stories of personal experience demonstrate. The inquiry in personal narratives identified that stories of lived experience critique and challenge the state of things offered by dominant narratives and engage in resistance and critique of available stories. The personal stories were also written in order to encourage reader to think with them (Frank, 1994) and through that process critically examine their own convictions about the SMP. Juxtaposition of the personal and dominant stories outlined the need for more narratives which would empower and support searcher. The new narratives were then written up. Original contributions to knowledge arising from this research are: challenge to the concept of search as exclusively belonging to adoption studies; identifying processes of marginalisation and stigmatisation arising from dominant narratives and offering these as alternative explanatory frameworks for searcher's behaviours; demonstrating how stories of lived experience critique dominant narrative landscape and providing new narratives of search inspired by personal experiences as means to empower searchers. This research is the most relevant for fields of adoption studies, family studies and socio psychological narrative inquiry.

Barsk, Viktor. "Time Series Search Using Traits." Thesis, Umeå universitet, Institutionen för datavetenskap, 2016. http://urn.kb.se/resolve?urn=urn:nbn:se:umu:diva-128580.
Full textAbstract:
Time series data occurs in many real world applications. For examplea system might have a database with a large number of time series, and a user could have a query like Find all stocks tha tbehave ”similarly” to stock A. The meaning of ”similarly” can vary between different users, use cases and domains. The goal of this thesis is to develop a method for time series search that can search based on domain specific patterns. We call these domain specific patterns traits. We have chosen to apply a trait based approach on top of a interest point based search method. First the search is conducted using a interest point method and then the results are ranked using the traits. The traits are extracted from sections of the time series and converted to a string representing its structure. The strings are then compared using Levenshtein distance to rank the search results. We have developed two types of traits. The new time series search method can be useful in many applications where a user is not looking for point-wise similarity, but rather looks at the general structure and some specific patterns. Using a trait based approach can better translate to how a user perceives time series search. The method can also yield more relevant results, since this new method can find results that a classic point-wise based search would rule out.

Full textAbstract:
Journalists in Iran work in a complex situation. In this study through conducting in-depth interviews with 12 Iranian journalists, I tried to understand this complex context. More specifically by conducting a critical discourse analysis on their words, I examined how these journalists make sense of their news work and what meanings emerge from it. I also, based on the framework of journalism ideology Deuze’s (2005), compared their meanings and values with mainstream journalists on a global level. I realized there are two main, even contrasting, categories of meaning for them. On the one hand, they feel frustrated about the future of their jobs at the personal level, and also the entire journalism profession at the broader level. In fact, they see how their job, both as a profession and as a social responsibility, is losing its importance. On the other hand, despite all those frustrating forces, they try to remain active. They engage in processes in order to make sense of their working lives. They attribute other meanings to their job in order to feel they are still useful, efficient, and influential. Iranian journalists are influenced more by the context, most importantly censorship and economic hardships, they live in rather than what they think are universal journalism norms.

Full textAbstract:
We conducted four experiments comprised of sequential auditory and visual searches in order to further explore the generalizability of the search asymmetry phenomenon to different sensory modalities, and to the sequential presentation of items in search arrays. It has been shown that search time to identify targets that contain features that distractors don’t have (feature-present targets) is faster than search time to identify targets that are missing features that distractors have (feature-absent targets). In Experiment 1 participants listened to auditory oddball sequences, consisting of two types of five-tone runs: the flat run, which consisted of five pure tones of the same frequency (the feature-absent target), and the change run, which consisted of four pure tones of the same frequency, followed by a fifth tone of a different frequency (the feature-present target). In some sequences the change runs were common and the flat runs were rare (the feature-present condition), while in other sequences these roles were reversed (the feature-absent condition). Experiments 2, 3 and 4 used the same protocol, however the visual stimuli consisted of rings (annuli) that differed by some feature (colour in Experiment 2, contrast in Experiment 3, and shade in Experiment 4). In all four experiments participant reaction times (RT) and electrophysiological (P300) responses to rare target patterns were recorded. In Experiments 1, 2 and 3, the reaction time and P300 latencies to identify feature-present targets were significantly faster than those to feature-absent targets, suggesting strong similarities between simultaneous visual search, and sequential auditory and visual search. What’s more, P300 responses to feature-present targets exhibited strong characteristics of both P3a and P3b subcomponents, while feature-absent responses only resembled that of the P3b. By contrast, the results of the fourth experiment were inconclusive. In Experiment 4 the saliency of the feature difference in the change runs was significantly reduced compared to that of the first three experiments, yielding longer reaction times and weaker P300 responses. Implications for the current understanding of search strategies associated with easy (feature-present) and difficult (feature-absent) searches, as well as the locus of the search asymmetry phenomenon, are discussed.Arts, Faculty of

Full textAbstract:
This work addresses applications of search theory where a mobile search agent seeks to find an unknown number of stationary targets randomly distributed in a bounded search domain. We assume that the search mission is subject to a time or distance constraint, and that the local environmental conditions affect sensor performance. Because the environment varies by location, the effectiveness of the search sensor also varies by location. Our contribution to search theory includes new decision-theoretic approaches for generating optimal search plans in the presence of false alarms and uncertain environmental variability. We also formally define the value of environmental information for improving the effectiveness of a search mission, and we develop methods for optimal deployment of assets that can acquire environmental information in order to improve search effectiveness. Finally, we extend our research to the case of multiple cooperating search agents. For the case that inter-agent communication is severely bandwidth-limited, such as in subsea applications, we propose a method for assessing the expected value of inter-agent communication relative to joint search effectiveness. Our results lead to a method for determining when search agents should communicate. Our contributions to search theory address important applications that range from subsea mine-hunting to post-disaster search and rescue applications.PHD

Jakucione, Indre. "In search of lost motherhood : the representation of the mother-daughter relationship in contemporary cinema." Thesis, Kingston University, 2017. http://eprints.kingston.ac.uk/41959/.
Full textAbstract:
In the ancient Homeric mother-daughter myth ‘Hymn to Demeter’ the goddess mother mourns the loss of her daughter Persephone. The bond between mother and daughter in the myth is presented so close that its forced separation endangers continuity of the human race. This thesis suggests that in our modern world the stories of mothers and the mother-daughter dyads are reversed. I argue that in contemporary Western cinema the patriarchal institution of motherhood still prevails with mothers lacking subjectivity and foregrounded voice, and daughters being deprived of positive role models, and regarding ‘idealised motherhood’ as the norm. Highlighting that the topic of this thesis is under-researched and in need of scholarly attention I aim to provide a pioneering critical examination of the representation of the mother-daughter relationship, motherhood, mothering, youthful femininities and daughterhood in contemporary cinema. All texts examined in this thesis are products of popular culture: they are topical, relatively commercially successful and influential Hollywood films. The dissertation consists of three interlocking parts according to the application of the generic approach and close textual analyses. Although each part is unified by the focus on a specific genre, such as the fairy-tale film, the horror film and the comedy, this thesis employs diverse methodologies in order to examine the genre texts. Moreover, recognising a new resurgence of interest in feminism in the media and among young women this thesis explores how feminism have informed the contemporary representations of youthful femininities, motherhood and generational relationships. Drawing upon recent studies of the fairy tale, genre studies, feminism, femininity and popular culture, I seek to advance the field of the representation of motherhood and daughterhood, aiming to make a scholarly contribution to the study of the representation of the mother-daughter dyad.

Full textAbstract:
Search theory allows the optimization of scarce resources to find a missing person in the shortest possible time. This work focuses on the central paradigm in search theory from a land-based search and rescue perspective: A search planner must send a resource where the subject is located, which is unknown. Original research furthered search theoery in probability of area (POA) by adding the dementia subject category, development of new spatial models, and creating the International Search and Rescue Incident Database (145,000 incidents). Research methodology required developing new data standards to integrate multiple databases. Twenty new subject categories were formulated from the research, as well as heuristic rules based upon search theory. In addition, several models were developed to help predict the location of missing aircraft. A program called Map-Score was created which quantizes the effectiveness of the models. This information has been widely adopted by search and rescue planners around the world. The second component is the conditional probability that the searcher/sensor would detect the subject if the subject were in the search area; this is known as probability of detection. Sweep width experiments have been carried out in order to develop the methodology, create tools to simplify the process, determine actual sweep width values for visual search, and to examine various correction factors. The visual methodology was modified in order to carry out the two-way search problem of detecting subject shouts in response to whistle-blasts along with characterizing clues on a trail. Finally, with enough sweep width experiments completed it was possible to determine the correlation between the easily obtained range of detection and the experimentally derived sweep width, providing a quick field estimation tool. Optimal resource allocation can be obtained by maximizing the probability of success rate. This is determined by using previous research to determine POA, sweep width values and additional research that determined searcher velocity by GIS analysis. Ultimately, all search theory is integrated into a tactical decision aid, which for the first time will allow the search and rescue planner to easily use search theory.

Full textAbstract:
Networked systems, such as telecom networks and cloud infrastructures, hold and generate vast amounts of conguration and operational data, only a small portion of which is used today by management applications. The overall goal of this work is to make all this data available through a real-time search process named network search , where queries are invoked, without giving the location or the format of the data, similar to web search. Such a capability will simplify many management applications and enable new classes of realtime management solutions. The fundamental problems in network search relate to search in a vast and dynamic information space and the fact that the information is distributed across a very large system. The thesis contains several contributions towards engineering a network search system. We present a weakly-structured information model, which enables representation of heterogeneous network data, a keyword-based search language, which supports location- and schema-oblivious search queries, and a distributed search mechanism, which is based on an echo protocol and supports a range of matching and ranking options. The search is performed in a peer-to-peer fashion in a network of search nodes. Each search node maintains a local real-time database of locally sensed conguration and operational information. Many of the concepts we developed for network search are based on results from the elds of information retrieval, web search, and very large databases. The key feature of our solution is that the search process and the computation of the query results is performed on local data inside the network or the cloud. We have build a prototype of the system on a cloud testbed and developed applications that use network search functionality. The performance measurements suggest that it is feasible to engineer a network search system that processes queries at low latency and low overhead, and that can scale to a very large system in the order of 100,000 nodes.QC 20130930

Full textAbstract:
Eine Zeitreihe ist eine zeitlich geordnete Folge von Datenpunkten. Zeitreihen werden typischerweise über Sensormessungen oder Experimente erfasst. Sensoren sind so preiswert geworden, dass sie praktisch allgegenwärtig sind. Während dadurch die Menge an Zeitreihen regelrecht explodiert, lag der Schwerpunkt der Forschung in den letzten Jahrzehnten auf der Analyse von (a) vorgefilterten und (b) kleinen Zeitreihendatensätzen. Die Analyse realer Zeitreihendatensätze wirft zwei Probleme auf: Erstens setzen aktuelle Ähnlichkeitsmodelle eine Vorfilterung der Zeitreihen voraus. Das beinhaltet die Extraktion charakteristischer Teilsequenzen und das Entfernen von Rauschen. Diese Vorverarbeitung muss durch einen Spezialisten erfolgen. Sie kann zeit- und kostenintensiver als die anschließende Analyse und für große Datensätze unrentabel werden. Zweitens führte die Verbesserung der Genauigkeit aktueller Ähnlichkeitsmodelle zu einem unverhältnismäßig hohen Anstieg der Komplexität (quadratisch bis biquadratisch). Diese Dissertation behandelt beide Probleme. Es wird eine symbolische Zeitreihenrepräsentation vorgestellt. Darauf aufbauend werden drei verschiedene Ähnlichkeitsmodelle eingeführt. Diese erweitern den aktuellen Stand der Forschung insbesondere dadurch, dass sie vorverarbeitungsfrei, unempfindlich gegenüber Rauschen und skalierbar sind. Anhand von 91 realen Datensätzen und Benchmarkdatensätzen wird zusätzlich gezeigt, dass die hier eingeführten Modelle auf den meisten Datenätzen die höchste Genauigkeit im Vergleich zu 15 aktuellen Ähnlichkeitsmodellen liefern. Sie sind teilweise drei Größenordnungen schneller und benötigen kaum Vorfilterung.A time series is a collection of values sequentially recorded from sensors or live observations over time. Sensors for recording time series have become cheap and omnipresent. While data volumes explode, research in the field of time series data analytics has focused on the availability of (a) pre-processed and (b) moderately sized time series datasets in the last decades. The analysis of real world datasets raises two major problems: Firstly, state-of-the-art similarity models require the time series to be pre-processed. Pre-processing aims at extracting approximately aligned characteristic subsequences and reducing noise. It is typically performed by a domain expert, may be more time consuming than the data mining part itself, and simply does not scale to large data volumes. Secondly, time series research has been driven by accuracy metrics and not by reasonable execution times for large data volumes. This results in quadratic to biquadratic computational complexities of state-of-the-art similarity models. This dissertation addresses both issues by introducing a symbolic time series representation and three different similarity models. These contribute to state of the art by being pre-processing-free, noise-robust, and scalable. Our experimental evaluation on 91 real-world and benchmark datasets shows that our methods provide higher accuracy for most datasets when compared to 15 state-of-the-art similarity models. Meanwhile they are up to three orders of magnitude faster, require less pre-processing for noise or alignment, or scale to large data volumes.

Full textAbstract:
This thesis looks at developing efficient methodology for analysing high dimensional time-series, with an aim of detecting structural changes in the properties of the time series that may affect only a subset of dimensions. Firstly, we develop a Bayesian approach to analysing multiple time-series with the aim of detecting abnormal regions. These are regions where the properties of the data change from some normal or baseline behaviour. We allow for the possibility that such changes will only be present in a, potentially small, subset of the time-series. A motivating application for this problem comes from detecting copy number variation (CNVs) in genetics, using data from multiple individuals. Secondly, we present a novel approach to detect sets of most recent changepoints in panel data which aims to pool information across time-series, so that we preferentially infer a most recent change at the same time point in multiple series. Lastly, an approach to fit a sequence of piece-wise linear segments to a univariate time series is considered. Two additional constraints on the resulting segmentation are imposed which are practically useful: (i) we require that the segmentation is robust to the presence of outliers; (ii) that there is an enforcement of continuity between the linear segments at the changepoint locations. These constraints add significantly to the computational complexity of the resulting recursive solution. Several steps are investigated to reduce the computational burden.

Full textAbstract:
To deter is central for strategic thinking. Some of the more astute observations regarding the dynamics of deterrence were made during the Cold War by game theorists. This set the stage for how deterrence has come to be studied. A strong methodological element like the research on deterrence’s reliance on game theory requires examination in order to understand what sort of knowledge it actually yields. What sort of knowledge does one acquire when deterrence is viewed through game theoretic models? How do they inform us about the phenomenon of deterrence? To understand the nature of a phenomenon through models requires idealization, which in turn presupposes assumptions. This licentiate thesis investigates the type of knowledge we attain when approaching deterrence from a game theoretic perspective. The two articles presented address two separate but related issues. The first article reviews a debate regarding which deterrence model best capture the phenomena of deterrence, i.e. how models can be compared to one and other. The article presents a framework for comparing models and then appraises how these different deterrence models inform us about deterrence. The second article uses one of the more central deterrence models in order to evaluate how and to what extent the naval operation Atalanta managed to deter the Somali piracy.QC 20190201

Identifying a globally optimal solution for an intractable discrete optimization problem is often cost prohibitive. Therefore, solutions that are within a predetermined threshold are often acceptable in practice. This dissertation introduces the concept of B-acceptable solutions where B is a predetermined threshold for the objective function value.
It is difficult to assess a priori the effectiveness of local search algorithms, which makes the process of choosing parameters to improve their performance difficult. This dissertation introduces the B-acceptable solution probability in terms of B-acceptable solutions as a finite-time performance measure for local search algorithms. The B-acceptable solution probability reflects how effectively an algorithm has performed to date and how effectively an algorithm can be expected to perform in the future. The B-acceptable solution probability is also used to obtain necessary asymptotic convergence (with probability one) conditions. Upper and lower bounds for the B-acceptable solution probability are presented. These expressions assume particularly simple forms when applied to specific local search strategies such as Monte Carlo search and threshold accepting. Moreover, these expressions provide guidelines on how to manage the execution of local search algorithm runs. Computational experiments are reported to estimate the probability of reaching a B-acceptable solution for a fixed number of iterations. Logistic regression is applied as a tool to estimate the probability of reaching a B-acceptable solution for values of B close to the objective function value of a globally optimal solution as well as to estimate this objective function value. Computational experiments are reported with logistic regression for pure local search, simulated annealing and threshold accepting applied to instances of the TSP with known optimal solutions.Ph. D.

Full textAbstract:
Email has become deeply embedded in many users' daily lives. To investigate how email features in users lives, particularly how users attend to email and get lost within it, I ran five studies that probed how users determined relevancy of messages, logged interactions with email, gathered diary entries related to individual sessions, and investigated the gratifications sought from email use. For the first study, I performed an exploratory experiment in the laboratory to determine how participants assessed the importance of individual emails (N=10). The next investigation I undertook involved three different studies, which I detail individually: a survey on email usage (N=54); a two-week study of email usage (N=20); and finally, the application of Attentional Network Test (N=9). My final study was to validate my findings around the reasons for attending to email, this was done through deploying a survey that followed the Uses and Gratification Theory tradition (N=52)
In my studies I found that the majority of attentional effort is around reading email and participating in conversations, as opposed to email management. I also found that participants attended to email primarily based on notifications, instead of the number of unread messages in their inbox. I present my results through answering several research questions, and leverage Conversation Analysis (CA), particularly conversation openings, to explicate several problematic aspects around email use. My findings point to inefficiencies in email as a communication medium, mainly, around how summons are (or are not) issued. This results in an increased burden on email users to maintain engagement and determine (or construct) the appropriate moment for interruption.
My findings have several implications: email triage does not seem to be problematic for the participants in my studies, somewhat in contrast to previous research; much of the problem around email, particularly emph{getting lost in email} is in managing the tension between promptly responding to messages while limiting engagement with email; due to the social nature of the problems with email, modifications to the email client are limited in their potential effectiveness to prevent getting lost and reduce email related anxiety.Ph.

Full textAbstract:
When entrepreneurs are searching for more information to develop their business ideas, they generally do not have enough time to do extensive research and thus are inclined to take shortcuts. This could undermine the rationality of their decisions, depending on what information is not found. However, one popular shortcut offers an interesting opportunity. By consulting experts, entrepreneurs can save time and, if they apply the search principles identified in this study, they can further avoid search obstacles, such as cognitive biases and poor decision framing. For example, by consulting skeptics of a technology, entrepreneurs can counteract their own optimism. While the right mitigation techniques for bias may seem obvious once the bias has been identified, acting pro-actively is not obvious and seems to require experience or prior learning. The results of this study were obtained by applying grounded theory on data obtained from semi-structured interviews. Nine interviews were done in Stockholm, Sweden. The interviewees included founders of companies, a business developer and a business coach for entrepreneurs.

Full textAbstract:
Economic uncertainty may affect significantly people’s behavior and hence macroeconomic variables. It is thus important to understand how people behave in presence of different kinds of economic risk. The present dissertation focuses therefore on the impact of the uncertainty in capital and labor income on the individual saving behavior. The underlying uncertain variables are here modeled as stochastic processes that each obey a specific stochastic differential equation, where uncertainty stems either from Poisson or Lévy processes. The results on the optimal behavior are derived by maximizing the individual expected lifetime utility. The first chapter is concerned with the necessary mathematical tools, the change-of-variables formula and the Hamilton-Jacobi-Bellman equation under Poisson uncertainty. We extend their possible field of application in order make them appropriate for the analysis of the dynamic stochastic optimization problems occurring in the following chapters and elsewhere. The second chapter considers an optimum-saving problem with labor income, where capital risk stems from asset prices that follow geometric L´evy processes. Chapter 3, finally, studies the optimal saving behavior if agents face not only risk but also uncertain spells of unemployment. To this end, we turn back to Poisson processes, which here are used to model properly the separation and matching process.

Full textAbstract:
In this thesis there is a set of waste disposal facilities, a set of customers at which waste is collected and an unlimited number of homogeneous vehicles based at a single depot. Empty vehicles leave the depot and collect waste from customers, emptying themselves at the waste disposal facilities as and when necessary. Vehicles return to the depot empty. We take into consideration time windows associated with customers, disposal facilities and the depot. We also have a driver rest period. The problem is solved heuristically. A neighbour set is defined for each customer as the set of customers that are close, but with compatible time windows. This thesis uses six different procedures to obtain initial solutions for the problem. Then, the initial solutions from these procedures are improved in terms of the distance travelled using our phase 1 and phase 2 procedures, whereas we reduce the number of vehicles used using our vehicle reduction (VR) procedure. In a further attempt to improve the solutions three metaheuristic algorithms are presented, namely tabu search (TS), variable neighbourhood search (VNS) and variable neighbourhood tabu search (VNTS). Moreover, we present a modified disposal facility positioning (DFP), reverse order and change tracking procedures. Using all these procedures presented in the thesis, four solution procedures are reported for the two benchmark problem sets, namely waste collection vehicle routing problems with time windows (VRPTW) and multi-depot vehicle routing problem with inter-depot routes (MDVRPI). Our solutions for the waste collection VRPTW problems are compared with the solutions from Kim et al (2006), and our solutions for the MDVRPI problems are compared with Crevier et al (2007). Computational results for the waste collection VRPTW problems indicate that our algorithms produce better quality solutions than Kim et al (2006) in terms of both distance travelled and number of vehicles used. However for the MDVRPI problems, solutions from Crevier et al (2007) outperform our solutions.

CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOTendo como ponto de partida a passagem da narrativa tradicional para o romance no advento da modernidade, tal como analisado por Walter Benjamin em especial no ensaio O narrador, este texto pretende investigar expressões literárias do processo de queda da experiência coletiva, que se deu com o surgimento da burguesia e das sociedades industrializadas no final do século XIX. Para tanto, será trabalhado o conceito benjaminiano de experiência (Erfahrung) e seu declínio na modernidade, bem como sua substituição pela vivência (Erlebnis), uma vez que o sentido da vida deixou de ser dado imediatamente na coletividade. No âmbito das formas artísticas, o romance teria se fixado, então, como um meio para a busca do sentido perdido a partir de uma perspectiva individual. Fazem parte desta trajetória as análises que Benjamin fez sobre a poesia lírica de Baudelaire, sobre o romance Em busca do tempo perdido de Proust e, ainda, sobre as noções de alegoria, memória, lembrança e morte. Os fragmentos de Infância em Berlim por volta de 1900 vêm compor, junto à Recherche proustiana, uma oportunidade de pensar o problema do tempo e discutir a possibilidade de uma construção da experiência na escrita.
Taking as a starting point the shift from traditional narrative to the novel at the beginning of modernity, as understood by Walter Benjamin, particularly in his essay The Storyteller, this text will investigate the literary expressions of the process of decline in collective experience that came about with the emergence of the bourgeoisie and industrial societies at the end of the 19th century. To do so, this work will examine Benjamin’s concept of experience (Erfahrung) and it’s decline in modernity, as well as its replacement by isolated experience (Erlebnis), since the meaning of life was no longer given immediately in collectivity. In the realm of artistic forms, the novel has been seen, therefore, as a way of finding the lost meaning from an individual perspective. The analyses that Benjamin makes of the lyric poetry of Baudelaire and the Proust novel In Search of Lost Time are part of this trajectory, as well as the notions of allegory, memory, remembrance and death. The fragments of Berlin Childhood around 1900, together with Proustian Recherche, offer an opportunity to reflect on the problem of time and discuss the possibility of the construction of experience in writing.

Full textAbstract:
The most popular methods for solving the shortest-path problem in
Artificial Intelligence are heuristic search algorithms. The main
contributions of this research are new heuristic search algorithms
that are either faster or scale up to larger problems than existing
algorithms. Our contributions apply to both online and offline tasks.
For online tasks, existing real-time heuristic search algorithms learn
better informed heuristic values and in some cases eventually converge
to a shortest path by repeatedly executing the action leading to a
successor state with a minimum cost-to-goal estimate. In contrast, we
claim that real-time heuristic search converges faster to a shortest
path when it always selects an action leading to a state with a
minimum f-value, where the f-value of a state is an estimate of the
cost of a shortest path from start to goal via the state, just like in
the offline A* search algorithm. We support this claim by implementing
this new non-trivial action-selection rule in FALCONS and by showing
empirically that FALCONS significantly reduces the number of actions
to convergence of a state-of-the-art real-time search algorithm.
For offline tasks, we improve on two existing ways of scaling up
best-first search to larger problems. First, it is known that the WA*
algorithm (a greedy variant of A*) solves larger problems when it is
either diversified (i.e., when it performs expansions in parallel) or
committed (i.e., when it chooses the state to expand next among a
fixed-size subset of the set of generated but unexpanded states). We
claim that WA* solves even larger problems when it is enhanced with
both diversity and commitment. We support this claim with our MSC-KWA*
algorithm. Second, it is known that breadth-first search solves
larger problems when it prunes unpromising states, resulting in the
beam search algorithm. We claim that beam search quickly solves even
larger problems when it is enhanced with backtracking based on limited
discrepancy search. We support this claim with our BULB algorithm. We
show that both MSC-KWA* and BULB scale up to larger problems than
several state-of-the-art offline search algorithms in three standard
benchmark domains. Finally, we present an anytime variant of BULB and
apply it to the multiple sequence alignment problem in biology.

Includes bibliographical references (p. 93-95).
This thesis presents the Monte Carlo Real-Time Belief Space Search (MC-RTBSS) algorithm, a novel, online planning algorithm for partially observable Markov decision processes (POMDPs). MC-RTBSS combines a sample-based belief state representation with a branch and bound pruning method to search through the belief space for the optimal policy. The algorithm is applied to the problem of aircraft collision avoidance and its performance is compared to the Trac Alert and Collision Avoidance System (TCAS) in simulated encounter scenarios. The simulations are generated using an encounter model formulated as a dynamic Bayesian network that is based on radar feeds covering U.S. airspace. MC-RTBSS leverages statistical information from the airspace model to predict future intruder behavior and inform its maneuvers. Use of the POMDP formulation permits the inclusion of different sensor suites and aircraft dynamic models. The behavior of MC-RTBSS is demonstrated using encounters generated from an airspace model and comparing the results to TCAS simulation results. In the simulations, both MC-RTBSS and TCAS measure intruder range, bearing, and relative altitude with the same noise parameters. Increasing the penalty of a Near Mid-Air Collision (NMAC) in the MC-RTBSS reward function reduces the number of NMACs, although the algorithm is limited by the number of particles used for belief state projections. Increasing the number of particles and observations used during belief state projection increases performance.
(cont.) Increasing these parameter values also increases computation time, which needs to be mitigated using a more efficient implementation of MC-RTBSS to permit real-time use.

Search engines have made a science of cataloging page content, but the data can age, becoming outdated and irrelevant.
By searching pages in real time in a localized area of the web, information that is retrieved is guaranteed to be available at the time of the search. The real-time search engines intriguing premise provides an overwhelming challenge. Since the web is searched in real time, the engine's execution will take longer than traditional search engines. The challenge is to determine what factors can enhance the performance of the real-time search engine.
This research takes a look at three components: traversal methodologies for searching the web, utilizing concurrently executing spiders, and implementing a caching resource to reduce the execution time of the real-time search engine. These components represent some basic methodologies to improve performance. By determining which implementations provide the best response, a better and faster real-time search engine can become a useful searching tool for Internet users.

Full textAbstract:
The bus and train driver scheduling problem involves assigning bus or train work to drivers in such a way that all the bus or train work is covered and the number of drivers and duty costs are minimised. This is complicated by the fact that there are many restrictions on the duty generation. The generate-and-select approach is at present the most successful for bus and train driver scheduling. It involves generating a set of legal potential driver duties from which a minimal and most efficient subset is selected. Filtering rules are often applied so that the set of potential duties generated would not be prohibitively large. Moreover, windows of relief opportunities (WROs), which provide ranges of opportunities for relieving drivers, are beyond the capability of being handled by the existing systems. The usual practice is to consider one, sometimes two, discrete times within each time window. Optimality of solution is therefore compromised. The research presented in this thesis focuses on solving the driver scheduling problem with WROs using a constructive approach, which builds and refines a single schedule iteratively. Filtering rules are unnecessary under the approach. The 2-opt heuristic approach is first investigated, during which the potential of constructive heuristics is explored. Based on the experience, the Tabu Search meta-heuristic approach is then investigated. Multi-neighbourhoods and an appropriate memory scheme, which are essential elements of Tabu Search are designed and tailored for the driver scheduling problem with WROs. Alternative designs have been tested and compared with best known solutions drawn from real-life data sets. The tabu search approach is very fast, can handle WROs, and has achieved results comparable to those based on mathematical programming approaches. Taking advantage of WROs, it can improve best known solutions obtained by the existing systems. Consequently, it could be incorporated into existing systems to improve the solution by taking advantage of WROs.
