    This dissertation explores the situation of twentieth-century art and literature becoming digital. Focusing on relatively small online collections, I argue for materially invested readings of works of print, sound, and cinema from within a new media context. With bibliographic attention to the avant-garde legacy of media specificity and the little magazine, I argue that the “films,” “readings,” “magazines,” and “books” indexed on a series of influential websites are marked by meaningful transformations that continue to shape the present through a dramatic reconfiguration of the past. I maintain that the significance of an online version of a work is not only transformed in each instance of use, but that these versions fundamentally change our understanding of each historical work in turn. Here, I offer the analogical coding of these platforms as “little databases” after the little magazines that served as the vehicle of modernism and the historical avant-garde. Like the study of the full run of a magazine, these databases require a bridge between close and distant reading. Rather than contradict each other as is often argued, in this instance a combined macro- and microscopic mode of analysis yields valuable information not readily available by either method in isolation. In both directions, the social networks and technical protocols of database culture inscribe the limits of potential readings. Bridging the material orientation of bibliographic study with the format theory of recent media scholarship, this work constructs a media poetics for reading analog works situated within the windows, consoles, and networks of the twenty-first century

    In audio time-scale modification (TSM), the duration of an audio recording is changed while retaining its local frequency content. In this thesis, a novel phase vocoder based technique for TSM was developed, which is based on the new concept of fuzzy classification of points in the time-frequency representation of an input signal. The points in the time-frequency representation are classified into three signal classes: tonalness, noisiness, and transientness. The information from the classification is used to preserve the distinct nature of these components during modification. The quality of the proposed method was evaluated by means of a listening test. The proposed method scored slightly higher than a state-of-the-art academic TSM technique, and similarly as a commercial TSM software. The proposed method is suitable for high-quality TSM of a wide variety of audio and speech signals.Äänen aika-asteikon muuttamisessa äänitteen pituutta muokataan niin, että sen paikallinen taajuussisältö säilyy samanlaisena. Tässä diplomityössä kehitettiin uusi, vaihevokooderiin pohjautuva menetelmä äänen aika-asteikon muuttamiseen. Menetelmä perustuu äänen aikataajuusesityksen pisteiden sumeaan luokitteluun. Pisteet luokitellaan soinnillisiksi, kohinaisiksi ja transienttisiksi määrittämällä jatkuva totuusarvo pisteen kuulumiselle kuhunkin näistä luokista. Sumeasta luokittelusta saatua tietoa käytetään hyväksi näiden erilaisten signaalikomponenttien ominaisuuksien säilyttämiseen aika-asteikon muuttamisessa. Esitellyn menetelmän laatua arvioitiin kuuntelukokeen avulla. Esitelty menetelmä sai kokeessa hieman paremmat pisteet kuin viimeisintä tekniikkaa edustava akateeminen menetelmä, ja samanlaiset pisteet kuin kaupallinen ohjelmisto. Esitelty menetelmä soveltuu monenlaisien musiikki- ja puhesignaalien aika-asteikon muuttamiseen

This method, that we have developed, is implemented here for an adaptive robot that can recognize and adapt to children's play styles in real time. The robot rewards well-balanced interaction styles and encourages children to engage in the interaction. The potential impact of such an adaptive robot in robot-assisted play for children with autism is evaluated through a study conducted with seven children with autism in a school. A statistical analysis of the results shows the positive impact of such an adaptive robot on the children's play styles and on their engagement in the interaction with the robot

    Science-based restoration monitoring of coastal habitats, Volume Two: Tools for monitoring coastal habitats

    Get PDF
    Healthy coastal habitats are not only important ecologically; they also support healthy coastal communities and improve the quality of people’s lives. Despite their many benefits and values, coastal habitats have been systematically modified, degraded, and destroyed throughout the United States and its protectorates beginning with European colonization in the 1600’s (Dahl 1990). As a result, many coastal habitats around the United States are in desperate need of restoration. The monitoring of restoration projects, the focus of this document, is necessary to ensure that restoration efforts are successful, to further the science, and to increase the efficiency of future restoration efforts

    When fish are not poisson :modelling the migration of Atlantic salmon (Salmo salar) and sea trout (Salmo trutta) at multiple time scales

    Get PDF
    PhD ThesisMigratory species undertake prolonged seasonal journeys; monitoring these movements is challenging but can sometimes be achieved by observations that taken locally and, ideally, using remote methods. Amongst the best known examples of migrating fish in Europe, are Atlantic salmon (Salmo salar) and sea trout (Salmo trutta) that migrate between river and seawater. Characteristics of habitat suitability, feeding opportunities, predation, as well as salmonid sensitivity and needs, vary throughout successive stages of their anadromous life cycle. Since the marine stage is the longest but is also challenging to monitor, in-river fish counters are of increasing importance in understanding salmonid patterns in abundance. The original contribution of this thesis lies in the use of modelling techniques to investigate salmonid migration, based on temporal observations produced by an electronic fish counter triggered by salmonid passage, as they return to spawn in the River Tyne. Small scale observation revealed seasonal differences; aggregation behaviour intensified during the middle of the migration season, and explanatory covariates varied in both their effect size and relevance to salmonid abundance. At the population scale, migration was highly driven by annual periodicity, abundance increased with river temperature and there was an NAO effect with a four year lag, underlining the importance of marine conditions to parent population and/or post-smolts. Differences between distinct populations of S. salar and S. trutta appeared related to a species-specific annual periodicity and oceanic conditions as salmonids return (more so for S. salar). State-space models suggested a complex demographic structure for the two species. There was a species identification learning curve that affected the data by 2007. A classification algorithm determined that observations are more likely to be S. salar for larger signal amplitude, within a higher river flow and earlier in the year; characteristics were too similar between the two species to reach a useful classification success rate (69%). The project overall suggests specificities relating to both species and age-class that cannot be addressed in depth with the collected data; emerging limitations and recommendations are discussed.Environment Agenc

    Altered Speech: A case-study of identity-driven speech in a Dissociative Identity Disorder system

    Get PDF
    The field of sociolinguistics has long been interested in how speech differs across groups. These studies have been focused on how demographic factors like class, race, and geographical region alter speech patterns. However, more recently, the agency of individuals to use language as a tool to construct a certain identity or persona has been highlighted (e.g., Podesva 2007; Eckert 1989; Eckert 2008). These studies are limited due to the nature of their methods, relying on either one individual with a limited scope of characteristics or on a larger group of people with many different variables at play other than identity. The present study aims to address these limitations by centering on a set of unique participants that allow for a more controlled study and larger scope of interest. Specifically, this paper examines identity’s role in the sociolinguistic variation of pitch, speech quality, speech rate, and distinct accent markers within one individual with multiple identities (a person with Dissociative Identity Disorder). Despite the clear linguistic differences that have been noted by many studying Dissociative Identity Disorder (DID), there have not been any studies that focus on the phonetic or phonological variables that differ in a single system. Through an examination of these variables, we propose that various elements of personal identity (including gender, age, and sexuality), as well as the alter’s function within the system, are what drive the linguistic decisions they make
