Separating Tweets from Croaks : Detecting Automated Twitter Accounts with Supervised Learning and Synthetically Constructed Training Data / : Automationsdetektion av Twitter-konton med övervakad inlärning och syntetiskt konstruerad träningsmängd

Teljstedt, Erik Christopher January 2016 (has links)
In this thesis, we have studied the problem of detecting automated Twitter accounts related to the Ukraine conflict using supervised learning. A striking problem with the collected data set is that it was initially lacking a ground truth. Traditionally, supervised learning approaches rely on manual annotation of training sets, but it incurs tedious work and becomes expensive for large and constantly changing collections. We present a novel approach to synthetically generate large amounts of labeled Twitter accounts for detection of automation using a rule-based classifier. It significantly reduces the effort and resources needed and speeds up the process of adapting classifiers to changes in the Twitter-domain. The classifiers were evaluated on a manually annotated test set of 1,000 Twitter accounts. The results show that rule-based classifier by itself achieves a precision of 94.6% and a recall of 52.9%. Furthermore, the results showed that classifiers based on supervised learning could learn from the synthetically generated labels. At best, the these machine learning based classifiers achieved a slightly lower precision of 94.1% compared to the rule-based classifier, but at a significantly better recall of 93.9% / Detta exjobb har undersökt problemet att detektera automatiserade Twitter-konton relaterade till Ukraina-konflikten genom att använda övervakade maskininlärningsmetoder. Ett slående problem med den insamlade datamängden var avsaknaden av träningsexempel. I övervakad maskininlärning brukar man traditionellt manuellt märka upp en träningsmängd. Detta medför dock långtråkigt arbete samt att det blir dyrt förstora och ständigt föränderliga datamängder. Vi presenterar en ny metod för att syntetiskt generera uppmärkt Twitter-data (klassifieringsetiketter) för detektering av automatiserade konton med en regel-baseradeklassificerare. Metoden medför en signifikant minskning av resurser och anstränging samt snabbar upp processen att anpassa klassificerare till förändringar i Twitter-domänen. En utvärdering av klassificerare utfördes på en manuellt uppmärkt testmängd bestående av 1,000 Twitter-konton. Resultaten visar att den regelbaserade klassificeraren på egen hand uppnår en precision på 94.6% och en recall på 52.9%. Vidare påvisar resultaten att klassificerare baserat på övervakad maskininlärning kunde lära sig från syntetiskt uppmärkt data. I bästa fall uppnår dessa maskininlärningsbaserade klassificerare en något lägre precision på 94.1%, jämfört med den regelbaserade klassificeraren, men med en betydligt bättre recall på 93.9%.

Self-Assembling Robots

Groß, Roderich 12 October 2007 (has links)
We look at robotic systems made of separate discrete components that, by self-assembling, can organize into physical structures of growing size. We review 22 such systems, exhibiting components ranging from passive mechanical parts to mobile robots. We present a taxonomy of the systems, and discuss their design and function. We then focus on a particular system, the swarm-bot. In swarm-bot, the components that assemble are self-propelled modules that are fully autonomous in power, perception, computation, and action. We examine the additional capabilities and functions self-assembly can offer an autonomous group of modules for the accomplishment of a concrete task: the transport of an object. The design of controllers is accomplished in simulation using techniques from biologically-inspired computing. We show that self-assembly can offer adaptive value to groups that compete in an artificial evolution based on their fitness in task performance. Moreover, we investigate mechanisms that facilitate the design of self-assembling systems. The controllers are transferred to the physical swarm-bot system, and the capabilities of self-assembly and object transport are extensively evaluated in a range of different environments. Additionally, the controller for self-assembly is transferred and evaluated on a different robotic system, a super-mechano colony. Given the breadth and quality of the results obtained, we can say that the swarm-bot qualifies as the current state of the art in self-assembling robots. Our work supplies some initial evidence (in form of simulations and experiments with the swarm-bot) that self-assembly can offer robotic systems additional capabilities and functions useful for the accomplishment of concrete tasks.

The melon produced belongs to the botanical group inodorus, yellow type, although the cultivars used present susceptibility to biotic stresses and, therefore, there is a need to search new germplasm in order to give support to melon breeding programs. On the other hand, there are melons cultivated by small farmers in the traditional agriculture of Northeast Brazil and a sample of these melons is stored in the Active Germplasm Bank of Cucurbits for the Northeast Brazil, located in the Semiarid Embrapa, at Petrolina-PE. Thus, the present study aimed at to estimate the genetic variability within and among melon accessions using morphological and molecular markers in order to identify the melon subspecies and their respective botanical groups. In the morphological characterization the parental e S1 generations were used recording quantitative and qualitative descriptors and some accessions were partitioned in subacessios. In the molecular characterization 28 ISSR primers were used. Using the morphological data is was possible to identify the subspecies agrestis with the botanical groupsmakwua and momordica and the subespecies melo with the botanical group cantalupensis. The UPGMA clusters showed great genetic diversity within and among the accessions and subaccessions. There was a reasonable agreement between the clusters based on morphological and molecular data, although the molecular data were more precise in the separation of the clusters. However, there is indication of introgression of traits of different subspecies and their botanical groups in the melon cultivated in the traditional agriculture of Northeast Brazil. / A produ??o do mel?o (Cucumis melo L.) no Brasil vem aumentando significativamente nos ?ltimos anos, sendo apreciado nos mercados internos e externos. O mel?o mais produzido ? do grupo bot?nico inodorus, tipo ?amarelo?, por?m, as cultivares apresentam suscetibilidade a estresses bi?ticos e, portanto, h? necessidade de busca por novo germoplasma para dar suporte aos programas de melhoramento de mel?o. Por outro lado, existem mel?es cultivados por pequenos agricultores e uma boa amostra desses mel?es foi coletada eencontra-se armazenada no BAG de Cucurbit?ceas para o Nordeste brasileiro localizado na Embrapa Semi?rido, Petrolina-PE. Assim, o presente estudo teve como objetivo estudar uma amostra de acessos de mel?o da agricultura tradicional e estimar a variabilidade gen?tica entre e dentro de uma amostra de acessos desses mel?es utilizando descritores morfol?gicos e moleculares, a fim de identificar as subesp?cies e seus respectivos grupos bot?nicos. Na caracteriza??o morfol?gica foram usadasas gera??es parentais e S1 utilizando descritores quantitativos e qualitativos e alguns acessos foram desdobrados em subacessos. Para a caracteriza??o molecular os subacessos foram analisados com 28 primers ISSR. Com os dados morfol?gicos foi poss?vel identificar a subesp?cie agrestis com os grupos bot?nicos makuwa e momordica e a subesp?cie melo com o grupo bot?nico cantalupensis.Os agrupamentos pelo m?todo UPGMA mostraram grande diversidade gen?tica entre e dentro dos acessos e dos subacessos. Houve uma razo?vel concord?ncia entre os dados morfol?gicos e moleculares, embora os dados moleculares foram mais precisos na separa??o dos grupos. Contudo, h? indica??o de que houve introgress?o de caracteres das diferentes subesp?cies e diferentes grupos bot?nicos no material cultivado pelos pequenos agricultores.

The first is a typical Neotropical microenvironment, called bromeliad phytotelm, which is formed by the accumulation of water and debris among the leaves of these plants. The bromeliads investigated in this study were sampled in areas of dense ombrophilus forest and mixed ombrophilus forest in southern Brazil (located at the ?Pro-Mata? Research Center), and belonged to the species Aechmea gamosepala Wittmack, Vriesea friburgensis Mez and Vriesea platynema Gaud. The collection comprised multiple individuals per species and also multiple samples (different tanks) from the same individual, making it possible to assess the complexity of the variation in these communities. The second environment consists of marine sediments collected in the Rio Grande Cone (located in southeastern Brazil, in the offshore portion of the Pelotas Basin), at depths of down to 18 meters below the seafloor. The samples originated from four different areas, with different geochemical characteristics and strong indications of the presence of chemosynthetic communities. This study demonstrated the presence of high biodiversity in both environments. We identified 30 prokaryotic phyla and 67 eukaryotic phyla in bromeliad phytotelmata, which seem to include both endemic organisms of this peculiar environment and organisms with ubiquitous distribution, common in freshwater or soil habitats. An interesting feature is that, in some cases, samples from different tanks of the same individual are more similar to tanks of other individuals (and even from other species) than between them. Thus, our results suggest that each bromeliad tank acts as an isolated body of water, where the effects of predation, competition and stochastic events such as wind-borne particles, fecal pellets and liquid excretions of terrestrial animals, dead leaves and animals can largely drive the community composition. Concerning the marine sediments, we observed the presence of 58 prokaryotic phyla, many of which are present in other chemosynthetic communities. Among these organisms were identified anaerobic methanotrophic archaeal groups and their syntrophic partners (sulfate-reducing bacteria), which together form a consortium with a significant role in the anaerobic oxidation of methane, a very important process that controls the emission of this greenhouse gas into the atmosphere. Statistical analysis performed in both studies sought to describe patterns of diversity of these communities at different spatial scales and to interpret them in the light of current knowledge about these environments. Overall, the results obtained in this thesis reveal in detail the complexity of these communities, opening new ways for further studies focusing on the processes that control their spatio-temporal dynamics. / O presente projeto aplicou a t?cnica de DNA metabarcoding, que visa caracterizar em larga escala a biodiversidade presente em determinada comunidade (atrav?s do sequenciamento do DNA total e sem a necessidade de cultivo ou isolamento), em dois ambientes brasileiros pouco explorados e com grande riqueza de esp?cies. O primeiro ? um microambiente t?pico da regi?o neotropical, denominado fitotelmo de brom?lia, o qual ? formado pelo ac?mulo de ?gua e detritos entre as folhas destas plantas. As brom?lias investigadas neste estudo foram amostradas em ?reas de Floresta Ombr?fila Densa e/ou Mista no sul do Brasil (localizadas no Centro de Pesquisas e Conserva??o da Natureza Pr?-Mata, PUCRS), e pertencem ?s esp?cies Aechmea gamosepala Wittmack, Vriesea friburgensis Mez e Vriesea platynema Gaud. A coleta englobou m?ltiplos indiv?duos por esp?cie e tamb?m m?ltiplas amostras (diferentes cisternas) do mesmo indiv?duo, possibilitando avaliar a complexidade da varia??o nestas comunidades. O segundo ambiente consiste de sedimentos marinhos coletados no Cone de Rio Grande (situado no sudeste do Brasil, na por??o offshore da Bacia de Pelotas), em profundidades de at? 18 metros abaixo do fundo do mar. As amostras s?o provenientes de quatro ?reas distintas, apresentando diferentes caracter?sticas geoqu?micas e fortes ind?cios da presen?a de comunidades quimiossint?ticas. Nossa investiga??o observou grande diversidade biol?gica em ambos os ambientes. Foram identificados 30 filos de procariotos e 67 filos de eucariotos nos fitotelmos de brom?lia, os quais parecem compreender tanto organismos end?micos deste ambiente peculiar como organismos com distribui??o cosmopolita, comuns em habitats de ?gua doce ou solo. Uma caracter?stica interessante ? que, em alguns casos, amostras provenientes de diferentes cisternas do mesmo indiv?duo s?o mais semelhantes a cisternas de outros indiv?duos (e mesmo de outras esp?cies) do que entre si. Desta forma, nossos resultados indicam que cada cisterna atua como um corpo d??gua isolado, onde os efeitos de preda??o, competi??o e eventos estoc?sticos como part?culas carregadas pelo vento, restos de folhas ou animais mortos, bem como excre??es de animais, podem interferir fortemente na composi??o espec?fica da comunidade local. Em rela??o aos sedimentos marinhos, observamos a presen?a de 58 filos procari?ticos, os quais compreendem diversos t?xons j? caracterizados em outras comunidades quimiossint?ticas marinhas. Entre estes organismos, foram identificadas arqueas metanotr?ficas e seus parceiros sintr?ficos (bact?rias redutoras de sulfato), que juntos formam um cons?rcio cujo papel ? fundamental na oxida??o anaer?bica do metano, um importante processo que controla a emiss?o deste g?s de efeito estufa para a atmosfera. An?lises estat?sticas realizadas em ambos os estudos buscaram descrever padr?es de diversidade destas comunidades em diferentes escalas espaciais, bem como interpret?-los ? luz do conhecimento atual sobre estes ambientes. De forma geral, os resultados obtidos nesta tese revelam em detalhe a complexidade destas comunidades, e abrem caminho para estudos mais aprofundados dos processos que controlam sua din?mica espa?o-temporal.

Motorisk förmåga hos vuxna med ADHD och ADD : En tvärsnittsstudie

Lind, Sara, Engdahl, Hanna January 2019 (has links)
Introduktion: Attention Deficit Hyperactivity Disorder, ADHD, är en vanlig neuropsykiatrisk diagnos hos vuxna i Sverige med en prevalens på 2,5%. Karakteristiska problem är hyperaktivitet, impulsivitet och ouppmärksamhet. Attention Deficit Disorder, ADD, är en form av ADHD som innebär problem med uppmärksamhet och koncentration. Kunskapen om förekomst av motorikstörningar hos vuxna personer med ADHD och ADD är ännu begränsad. Syfte: Undersöka och beskriva motorisk förmåga hos en grupp vuxna med ADHD och ADD samt jämföra eventuella skillnader mellan dessa grupper. Metod: Denna studie är en del av ett större projekt vid Neurorehab Sävar, Västerbotten. Motorisk förmåga bedömdes för 109 personer enligt The Bruininks-Oseretsky Test of Motor Proficiency second edition, som i vuxen ålder fått diagnosen ADHD eller ADD. Testet är uppdelat i fyra motoriska områden; Fine Manual Control, Manual Coordination, Body Coordination, Strength and Agility, och en summering av alla områden: Total Motor Composite. Datamaterialet analyserades med oparade t-test och Mann-Whitney U-test och jämfördes deskriptivt mot normativa data. Resultat: Gruppen med ADD hade signifikant bättre poäng i Fine Manual Control än gruppen med ADHD: 60 (9) respektive 53 (10.75), p=0.027. Enligt beskrivande kategorier för Total Motor Composite hade 36,5% ur gruppen ADHD en individpoäng som var under till väl under genomsnittet jämfört med normativa data och 61.5% lika med genomsnittet. Gruppen ADD var 41.1% under till väl under genomsnittet och 59% lika med genomsnittet. Konklusion: Gruppen med ADD förefaller ha bättre finmotorik än gruppen med ADHD. Resultaten indikerar att motoriken är nedsatt hos vuxna personer med ADHD/ADD för över 30%. Ytterligare forskning om motorikstörning, vuxna och diagnosen behövs.

台灣高鐵財務改善方案之研究─減資再增資之財務可行性

林坤銓 Unknown Date (has links)
台灣高鐵現況營運量不佳財務面臨困境。台灣高鐵為世界最大的BOT案,由於國內在高鐵興建之前,政府並無實施BOT工程的經驗。高鐵公司在興建期即籌資不順,資金不能到位,且營運三年來虧損累累,財務非常不堪,甚至一度面臨無法還本付息的窘境。但身為特許公司的高鐵原始發起人卻不肯增資,政府不但替高鐵公司作鉅額的融資保證,並且一再出資挹注,成為高鐵公司的最大股東。雖然高鐵公司有龐大的利息負擔及鉅額的折舊,但二者其實早在原先高鐵的財務計畫中,不應成為高鐵公司虧損的理由。財務困窘的主因為開始營運後,由於台灣社會人口的變遷與產業結構、經濟環境等都已經發生很重大的變化,原先投資計畫的運量預測與實際狀況的差異太大,使得高鐵公司營運三年多,便已虧損掉超過三分之二的資本額。此時,各方的批評聲浪不斷,而針對高鐵公司財務改善的建議,亦不曾間斷。 減資後再增資為改善高鐵財務的最佳方式。高鐵公司財務之所以陷入如此困境,政府秉持高鐵興建不能無、高鐵營運不能停及高鐵公司不能倒的精神,一再姑息,任由特許公司的發起人予取予求,難辭其咎。然而本文研究探討台灣高鐵的財務改善方案,結論為高鐵公司應辦理減資彌補虧損,讓高鐵原始發起人認賠出場,再由民間增資入股。如此方能符合BOT精神、民意期待及符合現實政治環境,其所受的社會衝撃最小並確保能吸引民間資金投入。而且,政府對高鐵的相關紓困政策,也才能有長期性及正當性。減資後再增資的方式,既然是最佳的改善高鐵財務方式,政府研討擬定因應對策時,首先應務實的作高鐵公司未來之財務可行性評估。 評估高鐵公司未來的財務可行性。在高鐵公司現已採取運量百分比法方式提列折舊及簽有低利率的專案融資契約現況下,並假設高鐵公司未來運量預估具有高度的準確性。本文經依高鐵公司運量百分比法之運量評估高鐵公司未來營收的財務可行性,經計算分析得出IRR約為6.78%、NPV約為406億元、PBY約為11年及DPBY約為18年。雖然分析結果NPV不高且回收期過長並非十分理想,但NPV為正值顯示高鐵公司未來的財務仍具有可行性。政府現已實質掌握高鐵公司的經營權,除加強站區開發等措施,達成既定運量目標。更應審慎研議,在適當時機辦理減資後再增資,引進民間投資者及成立新經營團隊。順利完成推動高鐵公司上市的目標,方能讓高鐵營運的利益由全民共享,符合公平正義及社會大眾的期待。

Användning av förstapersonsspel vid militär simulering av strid i bebyggelse / Usage of first person shooter in military simulation of combat on urbanized terrain

Hedström, Johan, Lindahl, Björn January 2003 (has links)
<p>The goal of this master thesis is to show the benefit of using computer games of the type First Person Shooter, FPS in the field of military simulations. The main focus in this is around a couple of topics. Creating the AI that controls the behaviour of the computer-controlled characters, the bots. Create an environment where it is possible to supervise the bots and also design a framework that enables cooperation between a group of bots, a squad. </p><p>The result is Total Unreal Studio, TUS, a program where it is possible to add bots to a squad, connect them to a game server and inspect what the bots are doing. Several maneuvers that could be applied to a squad has been implemented such as room clearing where the squad clear a building from eventual enemies, room by room and other different attacking strategies. Also it is very easy to create new maneuvres for a squad as effect of the design. </p><p>As the name of the program indicates, the well-known game Unreal Tournament is used as platform for the simulation. But because we use a interface between the game server and TUS, it is possible to switch to any other game and the interface is the only thing that has to be modified. To get good situation awareness a lot of node analysis is required, for instance calculating good sniping positions, pinch points and advantageous locations from where to perform an ambush.</p> / <p>Målet med detta examensarbete är att påvisa fördelen med att använda datorspel av typen FörstaPersonsSpel, FPS, inom militära simuleringar. Huvudinriktningen hos arbetet har rört ett flertal ämnen: att skapa det AI som kontrollerar beteendet hos datorkontrollerade karaktärer, så kallade botar, skapa en miljö där det är möjligt att övervaka botarna och även designa ett ramverk som möjliggör samarbete mellan botar i en grupp. </p><p>Resultatet av examensarbetet är Total Unreal Studio, TUS, en applikation där det är möjligt att lägga till botar i en grupp, ansluta dem till en spelserver och övervaka deras agerande. Flera manövrar för en grupp av botar finns redan implementerade. Ett par av dessa är rumsrensning där stridsgruppens uppgift är att rensa en byggnad från eventuella fiender rum för rum samt andra attackmanövrar. Designens utseende gör även att det är mycket enkelt att lägga till ytterligare manövrar om så önskas.</p><p>Som namnet på programmet indikerar används det välkända spelet Unreal Tournament som plattform för simuleringarna. Mellan spelet och TUS används gränssnittet Gamebots vilket gör det möjligt att byta till vilket spel som helst och det enda som behöver modifieras är gränssnittet. För att botarna ska kunna ta riktiga beslut behövs ett sätt att få uppfattning om omvärlden. Detta fås genom att analysera de navigeringsnoder som är utplacerade. Denna analys kan gå ut på att hitta bra krypskyttenoder eller fördelaktiga platser att anlägga bakhåll.</p>

A Domain Based Approach to Crawl the Hidden Web

Pandya, Milan 04 December 2006 (has links)
There is a lot of research work being performed on indexing the Web. More and more sophisticated Web crawlers are been designed to search and index the Web faster. But all these traditional crawlers crawl only the part of Web we call “Surface Web”. They are unable to crawl the hidden portion of the Web. These traditional crawlers retrieve contents only from surface Web pages which are just a set of Web pages linked by some hyperlinks and ignoring the hidden information. Hence, they ignore tremendous amount of information hidden behind these search forms in Web pages. Most of the published research has been done to detect such searchable forms and make a systematic search over these forms. Our approach here will be based on a Web crawler that analyzes search forms and fills tem with appropriate content to retrieve maximum relevant information from the database.
