Blonde hair is a potent and highly visible sign in western culture. Although the popularity and desirability of blonde hair in the West is well documented, since the 1950s, blonde hair has also generated many negative associations and these have contributed to myths around blondeness. In particular, women who dye their hair blonde find themselves in a paradoxical position; they simultaneously evoke desire and derision. This thesis uses the model of feminine masquerade outlined by Joan Riviere (1929) as a locus for discussing the transgressive potential of the knowing use of blondeness as a sign. When women wear blondeness in this way they embrace it as an oblique means to access privilege. This self-reflexivity allows women to enter sites of power that they are otherwise excluded from. Drawing on ideas of the carnivalesque, as described by Mikhail Bakhtin (1968), this thesis also proposes that the carnivalesque is employed by women in order to transgress patriarchal boundaries through an ironic masquerade of the archetypal blonde. These paradoxical meanings of blondeness are evoked in the work of performance artist Vanessa Beecroft. Beecroft stages both the reflexive awareness of today's blonde woman and the way in which she is shaped by socio-cultural forces beyond her control. Through reference to Beecroft's art, this dissertation builds upon the optimism and transgressive potential of Bakhtin's 'carnival' and Riviere's 'feminine masquerade' to re-present the identity/position of blonde women as one of agency and power.

Designing smarter vehicles, aiming to minimize the number of driverbased wrong decisions or accidents, which can be faced with during the drive, is one of hot topics of today&rsquos automotive technology. In the design of smarter vehicles, several research issues can be addressed
one of which is Traffic Sign Recognition (TSR). In TSR systems, the aim is to remind or warn drivers about the restrictions, dangers or other information imparted by traffic signs, beforehand. Since the existing signs are designed to draw drivers&rsquo
attention by their colors and shapes, processing of these features is one of the crucial parts in these systems. In this thesis, a Traffic Sign Recognition System, having ability of detection and identification of traffic signs even with bad visual artifacts those originate from some weather conditions or other circumstances, is developed. The developed algorithm in this thesis, segments the required color influenced by the illumination of the environment, then reconstructs the shape of partially occluded traffic sign by its remaining segments and finally, identifies it. These three stages are called as &ldquo
Segmentation&rdquo
, &ldquo
Reconstruction&rdquo
and &ldquo
Identification&rdquo
respectively, within this thesis. Due to the difficulty of analyzing partial segments to construct the main frame (a whole sign), the main complexity of the algorithm takes place in the &ldquo
Reconstruction&rdquo
stage.

Smart vehicles with capabilities of autonomous driving are a big revolution in automobile industry. The vehicles can sense their environment and react based on it. It replaces the manual driver. Recognition of traffic sign is an important enabler for autonomous driving. Camera installed in the vehicle captures the traffic sign on the road and they must be recognized accurately for triggering the suitable action. In this thesis both image processing and Euclidean distance matching are used to pre-process and classify the traffic signs and thresholding and thinning are applied on image for feature extraction. In this work, a simple, efficient traffic sign recognition system with low computational time and to achieve good accuracy is proposed. Time to classify the traffic sign is achieved in milliseconds and accuracy is maintained using the proposed system. Keywords: Autonomous Driving, Image processing, Thresholding, Thinning, Euclidean distance matching.

Motivated by the study of polytopes formed as the convex hull of permutation matrices and alternating sign matrices, several new families of polytopes are defined as convex hulls of sign matrices, which are certain {0,1,-1}--matrices in bijection with semistandard Young tableaux. This bijection is refined to include standard Young tableau of certain shapes. One such shape is counted by the Catalan numbers, and the convex hull of these standard Young tableaux form a Catalan polytope. This Catalan polytope is shown to be integrally equivalent to the order polytope of the triangular poset: therefore the Ehrhart polynomial and volume can be combinatorial interpreted. Various properties of all of these polytope families are investigated, including their inequality descriptions, vertices, facets, and face lattices, as well as connections to alternating sign matrix polytopes, and transportation polytopes.

The purpose of the thesis was to create a data glove that can translate ASL by reading the finger- and hand movements. Furthermore, the applicability of conductive fabric as stretch sensors was explored. To read the hand gestures stretch sensors constructed from conductive fabric were attached to each finger of the glove to distinguish how much they were bent. The hand movements were registered using a 3-axis accelerometer which was mounted on the glove. The sensor values were read by an Arduino Nano 33 IoT mounted to the wrist of the glove which processed the readings and translated them into the corresponding sign. The microcontroller would then wirelessly transmit the result to another device through Bluetooth Low Energy. The glove was able to correctly translate all the signs of the ASL alphabet with an average accuracy of 93%. It was found that signs with small differences in hand gestures such as S and T were harder to distinguish between which would result in an accuracy of 70% for these specific signs.Syftet med uppsatsen var att skapa en datahandske som kan översätta ASL genom att läsa av finger- och handrörelser. Vidare undersöktes om ledande tyg kan användas som sträcksensorer. För att läsa av handgesterna fästes ledande tyg på varje finger på handsken för att urskilja hur mycket de böjdes. Handrörelserna registrerades med en 3-axlig accelerometer som var monterad på handsken. Sensorvärdena lästes av en Arduino Nano 33 IoT monterad på handleden som översatte till de motsvarande tecknen. Mikrokontrollern överförde sedan resultatet trådlöst till en annan enhet via Bluetooth Low Energy. Handsken kunde korrekt översätta alla tecken på ASL-alfabetet med en genomsnittlig exakthet på 93%. Det visade sig att tecken med små skillnader i handgester som S och T var svårare att skilja mellan vilket resulterade i en noggrannhet på 70% för dessa specifika tecken.

This thesis presents an approach for automatically generating signing animations from a sign language notation. An avatar endowed with expressive gestures, as subtle as changes in facial expression, is used to render the sign language animations. SWML, an XML format of SignWriting is provided as input. It transcribes sign language gestures in a format compatible to virtual signing. Relevant features of sign language gestures are extracted from the SWML. These features are then converted to body animation pa- rameters, which are used to animate the avatar. Using key-frame animation techniques, intermediate key-frames approximate the expected sign language gestures. The avatar then renders the corresponding sign language gestures. These gestures are realistic and aesthetically acceptable and can be recognized and understood by Deaf people.

Pełny tekst źródłaStreszczenie:
American Sign Language (ASL) signs are claimed to be composed of four parameters: handshape, location, movement (Sto]çoe 1960) and palm orientation (Battison 1974). This paper focuses solely on handshape, that is, the configuration of the thumb and the fingers in a given sign. Handshape is significant in ASL and Chinese Sign Language (CSL); that is, minimal pairs exist for handshape in each. Thus, the two ASL signs in (1) differ in one parameter: the handshapes are different, but the location, palm orientation and movement are the same. Similarly, the two CSL signs in (2) differ in one parameter: handshape. A logical next question asks if handshapes are further divisible into parts; more specifically, are handshapes composed of distinctive features? This question is not new; in fact, researchers have made many proposals for ASL handshape features (Lane, Boyes -Braem and Bellugi, 1979; Mandel, 1981; Liddell and Johnson, 1985; Sandler, 1989; Corina and Sagey, 1988 and others). This paper focuses on the proposal of Corina and Sagey (1988). In Section 2, I outline the proposed system for the distinctive handshapes of ASL, of which [lateral] is a part. Then using data from ASL and CSL, I give three arguments in support of the claim that there is not sufficient justification in ASL or CSL for the feature [lateral]. First, I show in Section 3 that the prediction which follows from the claim that [lateral] applies only to the thumb, namely that the thumb behaves differently from the other fingers, is not borne out by CSL data. Second, I argue in Section 4 that since other features (proposed by Corina and Sagey, 1988) can derive the same phonetic effects as [lateral], [lateral] is unnecessary to describe thumb features in either ASL or CSL. Third, in Section 5, I use ASL and CSL data to argue that the notion of fingers as "specified" or "unspecified ", although intuitively pleasing, should be discarded. If this notion cannot be used, the feature [lateral] does not uniquely identify a particular set of handshapes. I show that CSL data suggests that two other features, [contact to palm] and [contact to thumb] are independently needed. With these two features, and the exclusion of [lateral], the handshapes of both ASL and CSL can be explained. In Section 6, the arguments against [lateral] are summarized.

Dans cette thèse, j’étudie le domaine des mots composés dans les langues des signes. La composition a été décrite comme étant une stratégie d’enrichissement du lexique des langues des signes, même dans des cas de langues des signes émergentes. J’aborde ce sujet au travers de trois approches principales : typologique/empirique, théorique et expérimentale.Dans la partie typologique/empirique, j’apporte une description approfondie des mots composés dans deux langues signées : la LIS et la LSF. Dans ce domaine, ma principale contribution est de proposer une typologie plus exhaustive des classificateurs en y incluant les formes simultanées.Dans la partie théorique, j’apporte une description formelle de la manière de dériver la typologie complète des mots composés présents dans ces deux langues.Mon objectif premier est de montrer que les mots composés peuvent être dérivés de différentes manières selon leurs propriétés, et que la dérivation morpho-syntaxique n’est pas le seul processus qui affecte les options combinatoires de composition. Les processus post-syntaxiques, et particulièrement la linéarisation, doivent avoir au minimum accès à des représentations partielles afin de distinguer les formes qui doivent être épelées de façon séquentielle et simultanée.Dans la partie expérimentale, je cherche à savoir si la réduction phonologique est une condition suffisante pour identifier les mots composés dans les langues signées. Ma principale contribution a été de montrer que l’importation des critères d’une langue des signes à une autre doit être réalisée avec une extrême précautionIn this dissertation, I investigate the domain of compounds in sign languages. Compounding has been documented as a key strategy to enrich the lexicon of sign languages even in situations of emergent sign languages. I address this topic with three main angles: typological/empirical, theoretical and experimental. In the typological/empirical part, I offer a thorough description of compounds in two sign languages: Italian and French Sign Language (LIS and LSF). I offer a refined and more comprehensive typology of compounds, in which classifiers and simultaneous forms are also taken into account.In the theoretical part, I provide a formal account of how to derive the whole typology of compounds found in LIS and LSF. I show i) that compounds can be derived in multiple ways depending on their morphosyntactic properties and ii) that morphosyntactic derivation is not the only process that affects the combinatorial options of compounding. Post-syntactic processes, especially linearization, have to have access to at least partial representations in order to distinguish between forms that have to be spelled out either sequentially or simultaneously.In the experimental part, I investigate whether phonological reduction is a sufficient condition to identify compounds in SL. I show that importing criteria from one SL to another can be done, but with extreme caution

The goal of the project was to create an extension to Internet Explorer forStatens Tjänstepensionsverk (SPV) which would give the staff the experience ofSingle sign-on (SSO) to external web service providers as well as manage andupdate their passwords in a secure manner. The survey focused on the providersPalasso, ProCompetence and Wera. The extension was created as a BrowserHelper Object (BHO) with C# in .NET. The solution was implemented as aCOM object in a DLL-file that was running in-process with the browser. Theprogram used a locally stored XML file containing URLs, usernames andencrypted passwords to the providers. When a user came to a login page theprogram collected the HTML elements on the page and populated them withdata from the file and logged in the user. Encryption and decryption was solvedwith a symmetric key that was stored in the program. In the XML file was alsothe date for the latest update of the password. If one month had passed, theprogram either gave the user an indication that the password needed to beupdated, or updated it automatically with a new generated password, dependingon the provider. The conclusion was that the extension worked as planned butthat there were improvements to be made regarding the possibility to add newsites to the system. The project also included an analysis of alternative optionsto solve the problem using JavaScript, Add-in Express, or via a portal page. Theconclusion was that none of these were an equally powerful tool as a BHO.

There are many types of road signs, each of which carries a different meaning and function: some signs regulate traffic, others indicate the state of the road or guide and warn drivers and pedestrians. Existent image-based road sign recognition systems work well under ideal conditions, but experience problems when the lighting conditions are poor or the signs are partially occluded. The aim of this research is to propose techniques to recognize road signs in a real outdoor environment, especially to deal with poor lighting and partially occluded road signs. To achieve this, hybrid segmentation and classification algorithms are proposed. In the first part of the thesis, we propose a hybrid dynamic threshold colour segmentation algorithm based on histogram analysis. A dynamic threshold is very important in road sign segmentation, since road sign colours may change throughout the day due to environmental conditions. In the second part, we propose a geometrical shape symmetry detection and reconstruction algorithm to detect and reconstruct the shape of the sign when it is partially occluded. This algorithm is robust to scale changes and rotations. The last part of this thesis deals with feature extraction and classification. We propose a hybrid feature vector based on histograms of oriented gradients, local binary patterns, and the scale-invariant feature transform. This vector is fed into a classifier that combines a Support Vector Machine (SVM) using a Random Forest and a hybrid SVM k-Nearest Neighbours (kNN) classifier. The overall method proposed in this thesis shows a high accuracy rate of 99.4% in ideal conditions, 98.6% in noisy and fading conditions, 98.4% in poor lighting conditions, and 92.5% for partially occluded road signs on the GRAMUAH traffic signs dataset.

Every Sign of Life introduces an approach to and motivational schema for personal health monitoring. It is an exploration of how to make information collected by personal health-monitoring devices fun and engaging, and consequently more useful to the non-specialist. In contrast to the common methodology of adding game elements to established biofeedback systems, the Every Sign of Life approach is to design and build games that use biosensor information to effect the game environment. This work tests the hypothesis that fun (the joy of learning, achieving, competing, etc.) is a way to achieve the goal of self-efficacy; to induce people to take care of their own health by altering their habits and lifestyles. One result is a basic architecture for personal health-monitoring systems that has led to an approach to the design of sensor peripherals and wearable computer components called "Extremity Computing." This approach is used to redefine biosensor monitoring from periodic to continuous (ultimately saving data over a lifetime). Another result is an approach to adding implicit biofeedback to computer games. This has led to a new genre of games called "Bio-Analytical Games" that straddles the boundary between sports and computer games. A series of studies of how to present health information to children and adults have demonstrated the ability of consumers to use bioinformatics without involving professionals.

Pełny tekst źródłaStreszczenie:
In light of the absence of codified standard varieties of British Sign Language (BSL) and German Sign Language (Deutsche Gebclrdensprache, DGS), there have been repeated calls for the standardisation of both languages primarily from outside the deaf communities. The development of standard varieties has been suggested to facilitate political recognition and the establishment of linguistic norms which could enable sign language users to gain equal access to education, administration and commerce. Although frequently labelled as sociolinguistic enquiry, much research in standardisation and language planning displays a certain preference for investigating the linguistic aspects of language. Explicit discussion of social-theoretical perspectives is scarce. In order to address this imbalance, this study focuses on the social aspect of the subject matter by investigating the concept of sign language standardisation from the perspective of deaf sign language teachers. Taking a comparative approach, research findings are based on 17 in-depth interviews conducted in Germany and the UK which were analysed drawing on grounded theory. Participants in both countries conceptualised sign language standardisation predominantly as externally imposed language change pertaining to the eradication of regional dialects. Given that in contrast to hearing learners of sign languages, participants did not regard regional variation as a problem but as a highly valued feature of BSL and DGS, sign language standardisation was seen as a threat to sign languages. Moreover, the subject matter was also perceived as embodying hearing people's hegemony by bringing to the fore traditional power imbalances between deaf people and hearing stake holders in the political and educational realms. This study is the first to explore and examine perceptions of and attitudes towards sign language standardisation in the UK and Germany. It thereby contributes to knowledge in respect to sign language sociolinguistics, as well as standardisation and language planning in the wider field. Moreover, taking an explicitly sociolinguistic approach and in drawing on social research methodology, this study offers an atypical perspective on the issue of language standardisation in general.

Les langues des signes (LS) se sont développées naturellement au sein des communautés de Sourds. Ne disposant pas de forme écrite, ce sont des langues orales, utilisant les canaux gestuel pour l’expression et visuel pour la réception. Ces langues peu dotées ne font pas l'objet d'un large consensus au niveau de leur description linguistique. Elles intègrent des signes lexicaux, c’est-à-dire des unités conventionnalisées du langage dont la forme est supposée arbitraire, mais aussi – et à la différence des langues vocales, si on ne considère pas la gestualité co-verbale – des structures iconiques, en utilisant l’espace pour organiser le discours. L’iconicité, ce lien entre la forme d’un signe et le sens qu’il porte, est en effet utilisée à plusieurs niveaux du discours en LS.La plupart des travaux de recherche en reconnaissance automatique de LS se sont en fait attelés à reconnaitre les signes lexicaux, d’abord sous forme isolée puis au sein de LS continue. Les corpus de vidéos associés à ces recherches sont souvent relativement artificiels, consistant en la répétition d’énoncés élicités sous forme écrite, parfois en LS interprétée, qui peut également présenter des différences importantes avec la LS naturelle.Dans cette thèse, nous souhaitons montrer les limites de cette approche, en élargissant cette perspective pour envisager la reconnaissance d’éléments utilisés pour la construction du discours ou au sein de structures illustratives.Pour ce faire, nous montrons l’intérêt et les limites des corpus de linguistes : la langue y est naturelle et les annotations parfois détaillées, mais pas toujours utilisables en données d’entrée de système d’apprentissage automatique, car pas nécessairement cohérentes. Nous proposons alors la refonte d’un corpus de dialogue en langue des signes française, Dicta-Sign-LSF-v2, avec des annotations riches et cohérentes, suivant un schéma d’annotation partagé par de nombreux linguistes.Nous proposons ensuite une redéfinition du problème de la reconnaissance automatique de LS, consistant en la reconnaissance de divers descripteurs linguistiques, plutôt que de se focaliser sur les signes lexicaux uniquement. En parallèle, nous discutons de métriques de la performance adaptées.Pour réaliser une première expérience de reconnaissance de descripteurs linguistiques non uniquement lexicaux, nous développons alors une représentation compacte et généralisable des signeurs dans les vidéos. Celle-ci est en effet réalisée par un traitement parallèle des mains, du visage et du haut du corps, en utilisant des outils existants ainsi que des modèles que nous avons développés. Un prétraitement permet alors de former un vecteur de caractéristiques pertinentes. Par la suite, nous présentons une architecture adaptée et modulaire d’apprentissage automatique de descripteurs linguistiques, consistant en un réseau de neurones récurrent et convolutionnel.Nous montrons enfin via une analyse quantitative et qualitative l’effectivité du modèle proposé, testé sur Dicta-Sign-LSF-v2. Nous réalisons en premier lieu une analyse approfondie du paramétrage, en évaluant tant le modèle d'apprentissage que la représentation des signeurs. L’étude des prédictions du modèle montre alors le bien-fondé de l'approche proposée, avec une performance tout à fait intéressante pour la reconnaissance continue de quatre descripteurs linguistiques, notamment au vu de l’incertitude relative aux annotations elles-mêmes. La segmentation de ces dernières est en effet subjective, et la pertinence même des catégories utilisées n’est pas démontrée de manière forte. Indirectement, le modèle proposé pourrait donc permettre de mesurer la validité de ces catégories. Avec plusieurs pistes d’amélioration envisagées, notamment sur la représentation des signeurs et l’utilisation de corpus de taille supérieure, le bilan est très encourageant et ouvre la voie à une acception plus large de la reconnaissance continue de langue des signesSign Languages (SLs) have developed naturally in Deaf communities. With no written form, they are oral languages, using the gestural channel for expression and the visual channel for reception. These poorly endowed languages do not meet with a broad consensus at the linguistic level. These languages make use of lexical signs, i.e. conventionalized units of language whose form is supposed to be arbitrary, but also - and unlike vocal languages, if we don't take into account the co-verbal gestures - iconic structures, using space to organize discourse. Iconicity, which is defined as the existence of a similarity between the form of a sign and the meaning it carries, is indeed used at several levels of SL discourse.Most research in automatic Sign Language Recognition (SLR) has in fact focused on recognizing lexical signs, at first in the isolated case and then within continuous SL. The video corpora associated with such research are often relatively artificial, consisting of the repetition of elicited utterances in written form. Other corpora consist of interpreted SL, which may also differ significantly from natural SL, as it is strongly influenced by the surrounding vocal language.In this thesis, we wish to show the limits of this approach, by broadening this perspective to consider the recognition of elements used for the construction of discourse or within illustrative structures.To do so, we show the interest and the limits of the corpora developed by linguists. In these corpora, the language is natural and the annotations are sometimes detailed, but not always usable as input data for machine learning systems, as they are not necessarily complete or coherent. We then propose the redesign of a French Sign Language dialogue corpus, Dicta-Sign-LSF-v2, with rich and consistent annotations, following an annotation scheme shared by many linguists.We then propose a redefinition of the problem of automatic SLR, consisting in the recognition of various linguistic descriptors, rather than focusing on lexical signs only. At the same time, we discuss adapted metrics for relevant performance assessment.In order to perform a first experiment on the recognition of linguistic descriptors that are not only lexical, we then develop a compact and generalizable representation of signers in videos. This is done by parallel processing of the hands, face and upper body, using existing tools and models that we have set up. Besides, we preprocess these parallel representations to obtain a relevant feature vector. We then present an adapted and modular architecture for automatic learning of linguistic descriptors, consisting of a recurrent and convolutional neural network.Finally, we show through a quantitative and qualitative analysis the effectiveness of the proposed model, tested on Dicta-Sign-LSF-v2. We first carry out an in-depth analysis of the parameterization, evaluating both the learning model and the signer representation. The study of the model predictions then demonstrates the merits of the proposed approach, with a very interesting performance for the continuous recognition of four linguistic descriptors, especially in view of the uncertainty related to the annotations themselves. The segmentation of the latter is indeed subjective, and the very relevance of the categories used is not strongly demonstrated. Indirectly, the proposed model could therefore make it possible to measure the validity of these categories. With several areas for improvement being considered, particularly in terms of signer representation and the use of larger corpora, the results are very encouraging and pave the way for a wider understanding of continuous Sign Language Recognition

Single sign-on (SSO) is a session verification mechanism that allows a client to use a single password and name combination to be able to access multiple applications. The mechanism validates the client for all the applications and eliminates the need for authentication prompts when a user switches between applications within a session. SSO mechanisms can be classified as software versus hardware or customer-requirements oriented versus server-side arrangements. The five commonly used mechanisms of Single Sign-On currently are: Web Single Sign-On, Enterprise Single Sign-On, Kerberos (or Ticket/Token Authentication), Open ID, and Federation or Federated Identity. SSO has the main benefit of allowing a user to access many different systems without having to log on to each and every one of them separately. However, SSO introduces a security risk as once an attacker gains access to a single system, then the attacker has access to all of the systems. This thesis describes SSO technology, the Security Assertion Markup Language, and the advantages and risks involved in using SSO. It examines authentication mechanisms and their suitability for SSO integration. The main emphasis is a description of a mechanism that ameliorates some of the disadvantages of SSO by monitoring the user behavior with respect to a template. If a user performs actions that fit the defined template behavior, then the post authentication mechanism will not get activated. If, on the other hand, a user does something unforeseen, the mechanism will not perform authentication for this user, but rather trigger manual authentication. If this manual authentication succeeds, then the user will continue to interact with the system, otherwise user session will be ended. This behavior extension authentication mechanism is a method that eases the authentication process in which users are not expected to remember any username and password that can be forgotten easily or have a biometric attribute that can change over time. This method can be integrated to existing web application without a major risk and increase in cost.Single sign-on (SSO) är en sessionkontrollmekanism som gör det möjligt för en kund att använda en ett enda par av lösenord och namn för att kunna få tillgång till flera olika program. Mekanismen validerar klienten för alla anrop och eliminerar behovet av ytterligare inloggningsdialoger när en användare växlar mellan program inom en session. SSO-mekanismer kan klassificeras enligt olika kriterier, såsom programvara kontra hårdvara eller kunder krav orienterade mot serversidan arrangemang. De fem vanligen använda mekanismerna för Single Sign-On är närvarande: Web Single Sign-On Enterprise Single Sign-On, Kerberos (eller Token autentisering), Open ID och Federation eller Federated Identity. SSO har den stora fördelen att en användare kan få tillgång till många olika system utan att behöva logga in på vart och ett av dem separat. Men SSO inför också en säkerhetsrisk i och med att tillgång till ett enda av systemen också automatiskt innebär tillgång till samtliga. Denna avhandling beskriver SSO-teknik, Security Assertion Markup Language, och fördelarna och riskerna med att använda SSO, samt undersöker autentiseringsmekanismer och deras lämplighet för SSO integration. Tyngdpunkten är en beskrivning av en mekanism som minskar några av nackdelarna med SSO genom att övervaka användarnas beteende med avseende på en mall. Om en användare utför åtgärder som passar det beteende som beskrivs av mallen, då den föreslagna mekanismen kommer att hantera autentiseringen automatiskt. Om, å andra sidan, en användare gör något oförutsett, kommer mekanismen inte att automatiskt utföra autentisering för den här användaren, utan utlöser manuellt autentisering. Om denna manuella autentiseringen lyckas, så kan användare fortsätta att fortsätta att interagera med systemet, annars kommer användarsessionen att avslutas. Denna beteendebaserade utvidgning av autentiseringsmekanismen är en lovande metod som minskar behovet av att komma ihåg många namn och lösenord, utan att lämna delsystem öppna till de säkerhetsproblem som uppstår i ren SSO, och utan att vara beroende av biometriska egenskaper som kan förändras över tiden. Denna metod kan integreras med befintliga webbaserade lösningar utan ökad risk och ökade kostnader.

In this thesis, real time detection of traffic signs using FPGA hardware is presented. Traffic signs have distinctive color and shape properties. Therefore, color and shape
based algorithms are chosen to implemented on FPGA. FPGA supports sufficient logic to implement complete systems and sub-systems.
Color information of images/frames is used to minimize the search domain of detection process. Using FPGA, real time conversion of YUV space to RGB space is performed. Furthermore, color thresholding algorithm is used to localize the sign in the image/video depending on the color.
Edges are the most important image/frame attributes that provide valuable information about the shape of the objects. Sobel edge detection algorithm is implemented on FPGA. After color segmentation, FPGA implementation of Sobel algorithm is used to find the edges of candidate traffic signs in real time. Later, radial symmetry based shape detection algorithm is used to determine circular
traffic signs.
Each FPGA implemented algorithm is tested by using video sequences and static images. In addition, combined implementation of color based and shape based algorithms are tested. Joint application of color and shape based algorithms are used in order to reduce search domain and the processing time of detection process.
Designing architecture on FPGA makes traffic sign detection system portable as a final product and relatively more efficient than the computer based detection systems. The resulting hardware is suitable where cost and compactness constraints are important.

Pełny tekst źródłaStreszczenie:
This thesis deals with two types of mathematical objects: alternating sign matrices and polytopes. Alternating sign matrices were first defined in 1982 by Mills, Robbins and Rumsey. Since then, alternating sign matrices have led to some very captivating research (with multiple open problems still standing), an outline of which is presented in the opening chapter of this thesis. Convex polytopes are extremely relevant when considering enumerations of certain classes of integer valued matrices. An overview of the relevant properties of convex polytopes is presented, before a connection is made between polytopes and alternating sign matrices: the alternating sign matrix polytope. The vertex set of this new polytope is given, as well as a generalization of standard alternating sign matrices to give higher spin alternating sign matrices. From a result of Ehrhart a result concerning the enumeration of these matrices is obtained, namely, that for fixed size and variable line sum the enumeration is given by a particular polynomial. In Chapter 4, we give results concerning the symmetry classes of the alternating sign matrix polytope and in Chapter 3 we study symmetry classes of the Birkhoff polytope. For this classical polytope we give some new results. In the penultimate chapter, another polytope is defined that is a valid solution set of the transportation problem and for which a particular set of parameters gives the alternating sign matrix polytope. Importantly the transportation polytope is a subset of this new polytope.

Sign bilingualism is one of several approaches to the education of deaf children in the UK Sign bilingualism seeks to introduce British Sign Language (BSL) to deaf children from an early age in order to establish a first language from which English, the majority language, can be acquired. However, there is little concensus on how deaf children's BSL development should be measured and no practical tools available to assist practitioners in this task. BSL assessments are needed to make baseline assessments, facilitate identification of language difficulties, indicate targets for remediation and evaluate the outcome of educational and therapy programmes for deaf children. This study describes the development of an assessment of British Sign Language development. Issues relating to the type of test required and which aspects of BSL to include are raised. Selection of subjects upon whom to base test development and standardisation are discussed. The BSL test of receptive grammar was initially piloted on 40 children from native signing backgrounds. Revisions were made to the test procedure and a number of unsuccessful items were eliminated prior to standardising the test on 135 children aged 3-13 years. Subjects were carefully selected from the wider population of deaf children as being those who were in optimal language learning contexts. Although this may be considered a small sample for standardising a test, it reflects a high proportion of the population of children who are developing BSL under ideal conditions. Following publication of the test, analysis of data from its use with a larger unselected sample of deaf children allowed comparisons to be made with those in the standardisation study. The results provide insights into the conditions under which deaf children may acquire BSL naturally, even when BSL is not the home language. Areas explored by the study include the comparative language acquisition paths, as measured by the test, of deaf and hearing children from deaf families and deaf children from hearing families with diverse experiences of BSL input.

Autonomous Driving and Advance Driver Assistance Systems (ADAS) are revolutionizing the way we drive and the future of mobility. Among ADAS, Traffic Sign Classification is an important technique which assists the driver to easily interpret traffic signs on the road. In this thesis, we used the powerful combination of Image Processing and Deep Learning to pre-process and classify the traffic signs. Recent studies in Deep Learning show us how good a Convolutional Neural Network (CNN) is for image classification and there are several state-of-the-art models with classification accuracies over 99 % existing out there. This shaped our thesis to focus more on tackling the current challenges and some open-research cases. We focussed more on performance tuning by modifying the existing architectures with a trade-off between computations and accuracies. Our research areas include enhancement in low light/noisy conditions by adding Recurrent Neural Network (RNN) connections, and contribution to a universal-regional dataset with Generative Adversarial Networks (GANs). The results obtained on the test data are comparable to the state-of-the-art models and we reached accuracies above 98% after performance evaluation in different frameworks

This thesis presents a system to recognise and classify road and traffic signs for the purpose of developing an inventory of them which could assist the highway engineers’ tasks of updating and maintaining them. It uses images taken by a camera from a moving vehicle. The system is based on three major stages: colour segmentation, recognition, and classification. Four colour segmentation algorithms are developed and tested. They are a shadow and highlight invariant, a dynamic threshold, a modification of de la Escalera’s algorithm and a Fuzzy colour segmentation algorithm. All algorithms are tested using hundreds of images and the shadow-highlight invariant algorithm is eventually chosen as the best performer. This is because it is immune to shadows and highlights. It is also robust as it was tested in different lighting conditions, weather conditions, and times of the day. Approximately 97% successful segmentation rate was achieved using this algorithm.Recognition of traffic signs is carried out using a fuzzy shape recogniser. Based on four shape measures - the rectangularity, triangularity, ellipticity, and octagonality, fuzzy rules were developed to determine the shape of the sign. Among these shape measures octangonality has been introduced in this research. The final decision of the recogniser is based on the combination of both the colour and shape of the sign. The recogniser was tested in a variety of testing conditions giving an overall performance of approximately 88%.Classification was undertaken using a Support Vector Machine (SVM) classifier. The classification is carried out in two stages: rim’s shape classification followed by the classification of interior of the sign. The classifier was trained and tested using binary images in addition to five different types of moments which are Geometric moments, Zernike moments, Legendre moments, Orthogonal Fourier-Mellin Moments, and Binary Haar features. The performance of the SVM was tested using different features, kernels, SVM types, SVM parameters, and moment’s orders. The average classification rate achieved is about 97%. Binary images show the best testing results followed by Legendre moments. Linear kernel gives the best testing results followed by RBF. C-SVM shows very good performance, but ?-SVM gives better results in some case.

This thesis details the theoretical framework, methods, and results of the design project “Log In or Sign up”. The result of this project is an ebook sharing the same title. It consists of short stories and poems that revolve around digital surveillance and its effects on the self and society. The writings explore how the digital sur- veillance ecosystem affects our behavior and self-image in ways that we might not even realize. The context is our digital lives in a time where we rely more and more on the internet for our daily activities. The writings attempt to portray the emo- tions we go through while using digital platforms that are designed to extract our personal data. The stories and poems are presented in an interactive layout. Along with the aforementioned topics this thesis also addresses the responsibility of design in creating advanced digital surveillance methods created by companies such as Google, Facebook, Amazon, and Microsoft. For example, through the gami- fication of social media, deceptive presentation of data protection rights, and cura- tion of content for emotional effect.

ABSTRACT
The City of Morro Bay, California – Sign Ordinance Update and Embarcadero District
Tourism-Oriented Directional Sign Plan
Erik Berg-Johansen
This report includes a Draft Sign Ordinance, a Tourism-Oriented Directional Sign Plan, and a background report for each product. The final products were created thought a process involving extensive research, community outreach, and detailed discussions among City of Morro Bay staff.
The Sign Ordinance
It was discovered that signs are important to business owners and residents due to their effect on both economic and aesthetic issues in communities. This report documents research of scholarly articles, case studies, and community outreach efforts. This report includes survey results and analysis that reveal the opinions of Morro Bay business owners, and also their ideas in regards to the sign ordinance update. According to many business owners, the current sign ordinance is convoluted, virtually unenforced, and unfairly applied. It was the goal of this project to hear what the community desires, and then apply this knowledge to a proposal that residents and business owners in Morro Bay approve of. The proposed sign ordinance aims to be fair and user-friendly, while ultimately enhancing community character and aesthetic quality in the future.
Tourism-Oriented Directional Sign Plan
The Tourism-Oriented Directional Sign Plan was created to promote tourism in the City of Morro Bay and negate the need for A-frame sign use in the Embarcadero District. The plan includes three alternatives that are intended to spur discussion among the Planning Commission when the proposal is presented. The background report associated with this plan is intended to provide the reasoning behind the proposals, and give readers of the plan background knowledge on directional signs in general. Similar to the sign ordinance background report, this report documents research of scholarly articles, case studies, and community outreach efforts.

How deaf children relate signs to written words was investigated. Thirty deaf children participated in a lexical decision task and a production task. On both tasks, the children recognized written words that form part of their sign lexicon more accurately and more quickly than words that do not. In the production task, the younger children made fewer errors on written words that share formational correspondences with their signed equivalents, whereas the older children did not. In the lexical decision task, the children recognized words that they signed correctly in the production task more accurately and more quickly than those words they fingerspelled correctly.These results indicate that deaf children organize their recognition of written words around their knowledge of sign language. Further, the children's responses to legal versus illegal pseudowords in the lexical decision task indicate that they can learn the orthographic rules of written English words.

This dissertation offers a characterization and an analysis of wh-questions in Catalan Sign Language, which show the particularity of placing wh-expressions canonically in sentence final position. This feature, specific to Sign Languages, has been difficult to deal with from traditional models, which have often considered that wh-movement is universally to the left and which have also often assumed that syntactic structure encodes information about the linear order of linguistic elements. The dissertation also argues that syntactic hierarchy and linear order are two different objects with a limited impact over one another, and that the latter is mainly dependent on the mechanisms of linguistic processing and, specifically, on Working Memory. In that sense, the hypothesis that the difference in the placing of wh-elements between Sign Languages and Spoken Languages is due to differences in Working Memory is put forwards. To explore it, the results of two experiments with Deaf and hearing participants are discussed.S'ofereix una caracterització i una anàlisi de les preguntes-que en Llengua de Signes Catalana, que presenten la particularitat d'ubicar preferentment les expressions-qu al final de l'oració. Aquesta característica, pròpia de les llengües de signes, ha estat difícil de tractar des de models tradicionals, que sovint han considerat que el moviment-qu és universalment cap a l'esquerra i que sovint han assumit que l'estructura sintàctica codifica informació respecte de l'ordre lineal dels elements lingüístics. Es proposa que la jerarquia sintàctica i l'ordre lineal són dos objectes diferents i amb un impacte limitat l'un sobre l'altre i que el segon depèn principalment de mecanismes de processament lingüístic i, específicament, de la Memòria de Treball. En aquest sentit, s'hipotetitza que la diferència en la ubicació dels elements-qu entre llengües de signes i llengües orals respon a diferències en la Memòria de Treball. Per a explorar aquesta hipòtesi, s'exposen els resultats de dos experiments amb participants Sords i oients.

This thesis is about a generalization of permutation theory. The concept of pattern avoidance in permutation matrices is investigated in a larger class of matrices - the alternating sign matrices. The main result is that the set of alternating sign matrices avoiding the pattern 132, is counted by the large Schröder numbers. An algebraic and a bijective proof is presented. Another class is shown to be counted by every second Fibonacci number. Further research in this new area of combinatorics is discussed.

The traffic sign detection and recognition system is an essential part of the driver warning and assistance systems. In this thesis, traffic sign recognition system is studied. We considered circular, triangular and square Turkish traffic signs. For detection stage, we have two different approaches. In first approach, we assume that the detected signs are available. In the second approach, the region of interest of the traffic sign image is given. Traffic sign is extracted from ROI by using a detection algorithm.
In recognition stage, the ring-partitioned method is implemented. In this method, the traffic sign is divided into rings and the normalized fuzzy histogram is used as an image descriptor. The histograms of these rings are compared with the reference histograms. Ring-partitions provide robustness to rotation because the rotation does not change the histogram of the ring. This is very critical for circle signs because rotation is hard to detect in circle signs. To overcome illumination problem, specified gray scale image is used.
To apply this method to triangle and square signs, the circumscribed circle of these shapes is extracted.
Ring partitioned method is tested for the case where the detected signs are available and the region of interests of the traffic sign is given. The data sets contain about 500 static and video captured images and the images in the data set are taken in daytime.

The present series of experiments tried to provide information about the associative value of the CS in backward conditioning and further our knowledge of approach behavior (APPR$\sp-$) towards a CS which signals absence of an aversive US. In all experiments, the US was a foot-shock (.5 mA, 2 sec) and the CS was a platform accessible for short time periods each trial. Time spent on the platform was used as a measure of APPR$\sp-$ behavior. Experiment 1 compared the effects of backward, differential, and explicitly unpaired procedures with a random procedure on the development of APPR$\sp-$ behavior. The results showed rapid acquisition of APPR$\sp-$ behavior in each of the experimental groups in comparison with the random group. In a subsequent retardation-of-acquisition test (forward pairings), all experimental groups showed gradual suppression of APPR$\sp-$ behavior, suggesting conditioned inhibition to the platform-CS in each of the experimental groups. Experiment 2 studied the effect of the number of backward pairings on APPR$\sp-$. The results showed that five or ten daily pairings were sufficient for the rapid acquisition of APPR$\sp-$ behavior, while one daily pairing produced WDR$\sp+$ behavior (a behavioral tendency opposite to APPR$\sp-$ behavior). In a subsequent retardation-of-acquisition test, the experimental group exposed to five daily pairings showed rapid suppression of APPR$\sp-$ behavior. These results were interpreted in terms of possible differential level of conditioned inhibition to the CS produced by differential number of US-CS pairings. Experiment 3 studied the effect of ITI lengths on the development of APPR$\sp-$ behavior in backward conditioning. A strong APPR$\sp-$ behavior was observed when the ITI range was long (2 to 4 min), but not when ITI range was sometimes short (10 sec) and sometimes long (5 min). These results showed that the CS must reliably signal a relatively long period without shock for the development of APPR$\sp-$ behavior. In Experiment 4, conditioned inhibition to the CS in backward pairings was evaluated independently of APPR$\sp-$ behavior, in the context of a conditioned suppression paradigm. The results showed that US-CS pairings procedure produced less suppression of drinking than CS-US pairings, but no response acceleration in comparison with the control condition. Time spent on the platform and behavioral observations failed to provide evidence of the inhibitory properties of the CS in the backward conditioning group possibly due to extinction during testing sessions. In conclusion, it seems that under specific conditions, the CS in backward conditioning acquires inhibitory associative value and a conditioned inhibition mechanism would be partly responsible for APPR$\sp-$ behavior. However, temporal contiguity seems to be an essential element to APPR$\sp-$ behavior. At a theoretical level, a modified stimulus substitution model could be considered as an alternative to a contingency model explaining APPR$\sp-$.

ABSTRACT Context: Communication is a primary human need and language is the medium for this. Most people have the ability to listen and speak and they use different languages like Swedish, Urdu and English etc. to communicate. Hearing impaired people use signs to communicate. Pakistan Sign Language (PSL) is the preferred language of the deaf in Pakistan. Currently, human PSL interpreters are required to facilitate communication between the deaf and hearing; they are not always available, which means that communication among the deaf and other people may be impaired or nonexistent. In this situation, a system with voice recognition as an input and PSL as an output will be highly helpful. Objectives: As part of this thesis, we explore challenges faced by deaf people in everyday life while interacting with unimpaired. We investigate state of art work done in this area. This study explores speech recognition and Machine translation techniques to devise a generic and automated system that converts English speech to PSL. A prototype of the proposed solution is developed and validated. Methods: Three step investigation is done as part of thesis work. First, to understand problem itself, interviews were conducted with the domain experts. Secondly, from literature review, it is investigated whether any similar or related work has already been done, state of the art technologies like Machine translation, speech recognition engines and Natural language processing etc. have been analyzed. Thirdly, prototype is developed whose validation data is obtained from domain experts and is validated by ourselves as well as from domain experts. Results: It is found that there is a big communication gap between deaf and unimpaired in Pakistan. This is mainly due to the lack of an automated system that can convert Audio speech to PSL and vice versa. After investigating state of the art work including solutions in other countries specific to their languages, it is found that no system exists that is generic and automated. We found that there is already work started for PSL to English Speech conversion but not the other way around. As part of this thesis, we discovered that a generic and automated system can be devised using speech recognition and Machine translation techniques. Conclusion: Deaf people in Pakistan lack a lot of opportunities mainly due to communication gap between deaf and unimpaired. We establish that there should be a generic and automated system that can convert English speech to PSL and vice versa. As part of this, we worked for such a system that can convert English speech to PSL. Moreover, Speech recognition, Machine translation and Natural language processing techniques can be core ingredients for such a generic and automated system. Using user centric approach, the prototype of the system is validated iteratively from domain experts.This research has investigated a computer based solution to facilitate communication among deaf people and unimpaired. Investigation was performed using literature review and visits to institutes to gain a deeper knowledge about sign language and specifically how is it used in Pakistan context. Secondly, challenges faced by deaf people to interact with unimpaired are analyzed by interviews with domain experts (instructors of deaf institutes) and by directly observing deaf in everyday life situations. We conclude that deaf people rely on sign language for communication with unimpaired people. Deaf people in Pakistan use PSL for communication, English is taught as secondary language all over Pakistan in all educational institutes, deaf people are taught by instructors that not only need to know the domain expertise of the area that they are teaching like Math, History and Science etc. but they also need to know PSL very well in order to teach the deaf. It becomes very difficult for deaf institutes to get instructors that know both. Whenever deaf people need to communicate with unimpaired people in any situation, they either need to hire a translator or request the unimpaired people to write everything for them. Translators are very difficult to get all the time and they are very expensive as well. Moreover, using writing by unimpaired becomes very slow process and not all unimpaired people want to do this. We observed this phenomena ourselves as instructors of the institutes provided us the opportunity to work with deaf people to understand their feelings and challenges in everyday life. In this way, we used to go with deaf people in shopping malls, banks, post offices etc. and with their permission, we observed their interaction. We have concluded that sometimes their interaction with normal people becomes very slow and embarrassing. Based on above findings, we concluded that there is definitely a need for an automated system that can facilitate communication between deaf and unimpaired people. These factors lead to the subsequent objective of this research. The main objective of this thesis is to identify a generic and an automated system without any human intervention that converts English speech into PSL as a solution to bridge the communication gap between deaf and unimpaired. It is identified that existing work done related to this problem area doesn’t fulfill our objective. Current solutions are either very specific to a domain, e.g. post office or need human intervention i.e. not automatic. It is identified that none of the existing systems can be extended towards our desired solution. We explored state of the art techniques like Machine translation, Speech recognition and NLP. We have utilized these in our proposed solution. Prototype of the proposed solution is developed whose functional and non functional validation is performed. Since none of existing work exactly matches to our problem statement, therefore, we have not compared the validation of our prototype to any existing system. We have validated prototype with respect to our problem domain. Moreover, this is validated iteratively from the domain experts, i.e. experts of PSL and the English to PSL human translators. We found this user centric approach very useful to help better understand the problem at the ground level, keeping our work user focused and then realization of user satisfaction level throughout the process. This work has opened a new world of opportunities where deaf can communicate with others who do not have PSL knowledge. Having this system, if it is further developed from a prototype to a functioning system; deaf institutes will have wider scope of choosing best instructors for a given domain that may not have PSL expertise. Deaf people will have more opportunities to interact with other members of the society at every level as communication is the basic pillar for this. The automatic speech to sign language is an attractive prospect; the impending applications are exhilarating and worthwhile. In the field of Human Computer Interface (HCI) we hope that our thesis will be an important addition to the ongoing research.

A sign pattern (matrix) is a matrix whose entries are from the set {+,–, 0}. A sign pattern matrix A is a spectrally arbitrary pattern if for every monic real polynomial p(x) of degree n there exists a real matrix B whose entries agree in sign with A such that the characteristic polynomial of B is p(x). All 3 × 3 SAP's, as well as tree sign patterns with star graphs that are SAP's, have already been characterized. We investigate tridiagonal sign patterns of order 4. All irreducible tridiagonal SAP's are identified. Necessary and sufficient conditions for an irreducible tridiagonal pattern to be an SAP are found. Some new techniques, such as innovative applications of Gröbner bases for demonstrating that a sign pattern is not potentially nilpotent, are introduced. Some properties of sign patterns that allow every possible inertia are established. Keywords: Sign pattern matrix, Spectrally arbitrary pattern (SAP), Inertially arbitrary pattern (IAP), Tree sign pattern (tsp), Potentially nilpotent pattern, Gröbner basis, Potentially stable pattern, Sign nonsingular, Sign singular

Road Sign Detection and Recognition (RSDR) systems provide an additional level of driver assistance, leading to improved safety for passengers, road users and vehicles. As part of Advanced Driving Assistance Systems (ADAS), RSDR can be used to benefit drivers (specially with driving disabilities) by alerting them about the presence of road signs to reduce risks in situations of driving distraction, fatigue ,poor sight and weather conditions. Although a number of RSDR systems have been proposed in literature; the design of a robust algorithm still remains an open research problem. This thesis aims to resolve some of the outstanding research challenges in RSDR, while considering variations in colour illumination, scale, rotation, translation, occlusion, computational complexity and functional limitations. RSDR pipeline is divided into three parts namely; Colour Segmentation, Shape Classification and Content Recognition. This thesis presents each part as a separate chapter, except for Colour Segmentation that introduces two distinct approaches for Road Sign region of interest (ROI) selection. The first approach in Colour Segmentation presents a detailed investigation of computer based colour spaces i.e. YCbCr, YIQ, RGB, CIElab, CYMK and HSV, whereas second approach presents the development and utilisation of an illumination invariant Combined Colour Model (CCM) on Gamma Corrected images containing road signs considering varying illumination conditions. Shape Classification of the road sign acts as second part of RSDR pipeline consisting on shape feature extraction and shape feature classification stages. Shape features of road signs are extracted by introducing Contourlet Transforms at the decomposition level-3 with haar filters for generating the Laplacian Pyramid (LP) and Directional Filter Bank (DFB). The third part of the RSDR system presented in this thesis is the Content Recognition, which is carried out by extracting the LESH (Local Energy based Shape Histogram) features of the normalized road sign contents. Extracted shape and content features are utilised to train a Support Vector Machine (SVM) polynomial kernel which are later classified with the input candidate road sign shapes and contents respectively. The thesis further highlights possible extensions and improvements to the proposed approaches for RSDR.

This thesis investigates non-arbitrariness in novel sets of signs (mappings between signals and meanings). Two common ways of characterizing signs – by the degree of motivatedness they exhibit and by the degree of systematic compositionality they exhibit – are not necessarily orthogonal. Thus, the emergence of arbitrariness and of systematic compositionality in language should be studied together. We focus on a particular interface of the two properties: the systematic re-use of arbitrary elements. Previous work that demonstrates how novel signs can emerge and then evolve to become arbitrary does not measure systematic compositionality. On the other hand, previous work on systematic compositionality proposes a mechanism for the evolution of systematic compositionality and a measure of the property, but does not address the evolution of arbitrariness. We propose a parallel theory of the emergence of the systematic re-use of arbitrary elements. Systematic compositionality emerges in novel, motivated signs and is maintained as the signs become arbitrary. We report a series of experiments that probe how the systematic re-use of arbitrary elements arises in novel communication systems. In Experiment 1, partners must create signs from scratch to communicate about items that share semantic features. The systematic re-use of arbitrary elements emerges. Further, the evolution of arbitrariness and systematic compositionality are parallel: even participants’ first drawings of items are systematically compositional, and this systematic compositionality is maintained as the signs become arbitrary. Experiment 2 demonstrates that naïve participants, who played no role in – indeed, did not even observe – the creation of the sign systems, can nonetheless detect the systematic compositionality in them and generalize from it. Experiment 3 shows that participants actually do make use of the systematic re-use of arbitrary elements that they observe in others’ sign systems, when faced with the task of communicating (rather than learning and reproducing). The systematic compositionality is not only maintained, but appears to be increasing, over generations of participants observing others’ signs. The increase in systematic compositionality occurs when pairs create signs for items they have not observed – presumably, as they generalize using the systematic compositionality they have observed. In sum, we present an alternative mechanism for the emergence of the systematic reuse of arbitrary elements: arbitrariness and systematic compositionality emerge in a parallel fashion within the dyad, and subsequent communicators maintain – or even increase – the structure they have observed. More generally, we demonstrate the importance of examining arbitrariness and systematic compositionality together.

Negligence of the health care representatives during emergency situations causes numerous deaths in the hospitals. Developing an efficient, quick and reliable health care monitor with emergency control can help reduce human errors. This project is based on monitoring patients admitted in hospitals. It is a health monitoring device which measures the heart rate, blood pressure and body temperature of patients. After the vitals are measured accurately, it transmits them wirelessly to a monitoring room using ZigBee. In emergency situations, abnormal vitals are sent to the doctor and the emergency contact using a GSM module. There are many monitoring systems using Bluetooth, but monitoring using ZigBee has many advantages. There is a new approach by adding a GSM module, as the vitals can be received on any telephone as a SMS. This is very useful when they need to be sent to an emergency contact or the doctor in charge. This elementary, cost efficient health monitoring system is based on a simple controller. The main result achieved by this approach is the reduction of the micro controller processing time by twelve, due to which the end to end execution time of the system is also reduced. The heart rate of the patient is also measured with medically approved equipment unlike the previous models.

Målet med arbetet är att gestalta personlig utveckling. En bok, med syfte att långsiktigt generera förståelse genom insikt i vikten av inlevelseförmåga och föreställningsförmåga. Design för alla, innebär att vi når ett högre resultat med hjälp av personer som besitter spetskompetens, en elit. Å ena sidan de som med framgång brukar resultat som redan finns. Å andra sidan de med funktionshinder inom samma område och därför har svårt att förlika sig med den befintliga situationen. Dessa två grupper leder oss från ett tidigt stadium, i det här fallet, till en högre kvalitativ nivå av gestaltningen.

This thesis is a mark-making as a praxis of architectural experiment, which could be a noise and a revolutionary line as well. Neither of them don't matter to me as much as what I've got through a series of trial and error.
Composed of five related praxes, four preceding ones suggesting ideas of final praxis.
The corpus of idea is driven by the nomadic nature of human body and its micro environments. As I titled, is rather a graphical metaphor of being, situating, existing in the environment.
Due to its intimacy to the body, fabrics are chosen as materials. This attempt intended to sit in the blurred border line between the unavoidable image of hardness in architecture and structureless in garments (fashion).
is also implying the potential development in subject matter "homelessness". Since this project mainly concerns to being "nomadic", many homeless life styles were referenced.
At this point, this project could be a guideline or a pattern to build a nomadic shelter for the needs. With further surveys and studies, however, this project shall be developed one step ahead.
is the environment which integrates the body and its surroundings into a closed space. is a garment providing comfort and protection that the nomadic nature of human body requires. is clothing that is extended layers enabling the creation of transient space. is mobile space using body media. is visual intervention rendering place and boundary. is instinctive human reaction to fit themselves to the environment.

A nova era da informação que se está a assistir tem possibilitado a criação de novas e vastas coleções de intelecto virtual, como por exemplo o Wikipedia, Corsera, entre outros. Estas ferramentas vieram possibilitar a procura por cultura, resoluções de problemas do quotidiano, novos métodos de aprendizagem, por parte da sociedade em geral. Porém, como é habitual, tem-se vindo a verificar uma certa dificuldade inerente por parte de certas minorias sociais, que não possuem as mesmas capacidades de um indivíduo “normal“.
Esta dissertação tem como objetivo a criação de uma ferramenta, em formato de jogo sério, para apoiar o ensino de Língua Gestual Portuguesa a um público ouvinte o -“Kinect Sign”. Com este estudo pretende-se explorar as mais recentes ferramentas de desenvolvimento de jogos, mais conhecidas como Authoring Tools e a sua integração com Natural User interfaces, concretamente o sensor Kinect. A solução apresentada neste documento propõe a utilização desta ferramenta a todos os indivíduos iniciantes que necessitem de uma introdução a esta forma de comunicação, para tornar um pouco menos agressiva a entrada no complexo mundo da linguagem gestual.
A validação deste trabalho consistiu no desenvolvimento de um jogo protótipo que incentive os jogadores a aprenderem enquanto jogam. Analisaram-se problemas e tecnologias atuais para se chegar a uma estruturação semelhante a um jogo comum disponível em qualquer superfície comercial e websites dedicados ao género. Posterior apresentação a uma população selecionada a fim de analisar a sua opinião e utilidade do modelo desenvolvido, seguindo-se a resposta a um pequeno questionário.
