El presente proyecto de investigación está interesado en explorar y describir determinadas formas de sociabilidad de varones de clase media auto definidos como homosexuales entre el inicio de la última dictadura (1976) y la formación de un circuito de discos y pubs gays en la ciudad de Córdoba durante el llamado “destape alfonsinista” (1986). La investigación contempla la descripción densa de dos series de prácticas de sociabilidad. Por una parte, se analizará la sociabilidad de varones homosexuales, especialmente de un conjunto de sujetos que desempeñaban determinadas profesiones como “decoradores”, “modistos”, “cocineros”, “anticuarios” y organizadores de fiestas, contratados por las elites locales y clases medias acomodadas para diseñar sus formas de diversión durante el período. ¿Cómo estos sujetos se relacionaban con quienes no forman parte del “ambiente” homosexual y cómo gestionaban el “secreto público” de su identidad erótico-sexual en sus relaciones con las elites cordobesas? El estudio de estas formas de sociabilidad homosexual escasamente trabajadas por la literatura internacional se relacionará con un análisis de las formas de sociabilidad entre varones homosexuales y la formación de un “ambiente”. Para ello se estudiarán espacios colectivos de socialización como baños públicos, plazas, calles, fiestas privadas, bares, boliches y saunas. Los códigos de comunicación verbal y gestual utilizados en esos espacios, y la caracterización de las redes de personas que componían el “ambiente” también serán objeto de análisis. Dado el carácter inicial de esta investigación, ya que no se cuenta con estudios previos para Córdoba, proponemos la siguiente hipótesis de tipo exploratorio en relación a las formas de sociabilidad de determinados varones homosexuales: Estos sujetos habrían asegurado su reproducción social tanto como la posesión de ciertos salvoconductos para el ejercicio de su identidad sociosexual produciendo fiestas de las elites locales. A partir de erigirse en árbitros del “buen gusto” dichos sujetos habrían asegurado ciertos privilegios, entre ellos “feminizar” sus gustos y producirse como “locas”. Dada las nuevas condiciones impuestas por la recuperación democrática, los salvoconductos se hicieron cada vez menos valiosos al mismo tiempo que se formaba una identidad “gay” que, aunque buscó distanciarse del modelo negativo de “la loca”, continuó reclamando su dominio sobre el “buen gusto”. De esta manera, el cultivo experto del “buen gusto” sería parte de las prácticas que organizaban las formas de sociabilidad de varones homosexuales con sujetos heterosexuales de las elites. En relación a las formas de sociabilidad entre homosexuales proponemos que durante la dictadura, “el ambiente” se habría organizado en torno a un circuito callejero y una territorialidad de eventos privados (fiestas negras). Las diferentes performances sociales desarrolladas en tales espacios formaron parte de prácticas que desafiaron el estado de sitio impuesto. Reprimidas por la dictadura, estas prácticas no podían formar parte de un consumo cultural mercantilizado. La recuperación democrática y los cambios en las políticas del Estado con relación a los derechos y los reclamos de las minorías articulados con la expansión de un mercado gay global, habrían producido un cambio en las formas de sociabilidad homosexual. El ejercicio de esta sociabilidad supuso cada vez más el consumo de ciertas mercancías culturales asociadas con “la noche”. Así, la formación de una identidad “gay”, como opuesta al modelo “loca/chongo” dominante hasta los años ´80, aparecería fuertemente relacionada con la formación y segmentarización de un mercado del entretenimiento nocturno. Para la recolección de datos se recurrirá a entrevistas focalizadas e historias de vida de sujetos que trabajaron dando forma a las prácticas de divertimento nocturno de las elites locales y participaron en las redes de personas que componían el “ambiente”. This research project aims at exploring and describing determined forms of sociability among middle class self-identified as homossexual males betwwen the beginning of the last dictatorial period (1976) and the establishment of a network of disco and gay pubs in Cordoba, AR, during the so called “destape alfonsinista” (1986). This research will deal with the thick description of two series of sociability practices. On the one hand, it will analyze male homossexuals sociability practices themselves, barely studied in international literature, mainly those of a set of subjects whose professional careers were those of interior decorators, dressmakers, kitchen chefs, antiquarians and party promoters hired by the local elites and upper middle classes to design their forms of leisure durign that period. On the other, we will deal with the forms of sociability between male homossexuals and the the set of a social environment. This rearch will study collective spaces of socialization such as restrooms, squares, streets, private parties, pubs, discos and saunas. The communication codes in those spaces, both verbal and gestural, as well as the description of the social networks componing that enviroment will also be considered. Focused interviews with and life histories of those who worked structuring night leisure local elite practices and were part of that environment social networks will be the main techniques used in data collection.

Transmission of Cherenkov light through the atmosphere is strongly influenced by the optical clarity of the atmosphere and the prevailing weather conditions. The performance of telescopes measuring this light is therefore dependent on atmospheric effects. This thesis presents software and hardware developed to implement a prototype sky monitoring system for use on the proposed next-generation gamma-ray telescope array, VERITAS. The system, consisting of a CCD camera and a far-infrared pyrometer, was successfully installed and tested on the ten metre atmospheric Cherenkov imaging telescope operated by the VERITAS Collaboration at the F.L. Whipple Observatory in Arizona. The thesis also presents the results of observations of the BL Lacertae object, 1ES1959+650, made with the Whipple ten metre telescope. The observations provide evidence for TeV gamma-ray emission from the BL Lacertae object, 1ES1959+650, at a level of more than 15 standard deviations above background. This represents the first unequivocal detection of this object at TeV energies, making it only the third extragalactic source seen at such levels of significance in this energy range. The flux variability of the source on a number of timescales is also investigated.

The research conducted for this thesis has been carried out over a two year period as part of the Mobile Tools and Technology for customer care (MOTTO) project. The project was funded under the Applied Grant scheme administered by Enterprise Ireland and Nortel Networks Ltd. It was a partnership project between Galway-Mayo Institute of Technology, University of Limerick, National University of Ireland Galway, and a global Internet and communications company, Nortel Networks. The project aimed to investigate the enabling mobile communications technologies in e-Business and mobile communications in the area of Business-to-Business (B2B) customer care. The development of the application discussed in this thesis was developed in conjunction with the Galway-Mayo Institute of Technology, University of Limerick and AMT Ireland. The decision to develop the application in the Electronics Company of AMT in Limerick came about as a result of the contact established by Mark Southern from the University of Limerick. Mark was involved in overseeing the development and assisted in establishing the user requirements.

This paper devotes to evaluation of performance bottlenecks and algorithm deficiencies in the area of contemporary reliable multicast networking. Hereby, the impact of packet delay jitter on the end-to-end performance of multicast IP data transport is investigated. A series of tests with two most significant open-source implementations of reliable multicast is performed and analyzed. These are: UDP-based File Transfer Protocol (UFTP) and NACK-oriented Reliable multicast (NORM). Tests were targeted to simulate scenario of content distribution in WAN – sized Content Delivery Networks (CDN). Then, results were grouped and averaged, by round trip time and packet losses. This enabled us to see jitter influence independently on round trip time(RTT) and packet loss rates. Revealed jitter influence for different network conditions. Confirmed, that appearance of even small jitter causes significant data rate reduction.

Telecommunications and network technology is now the driving force that ensures continued progress of world civilization. Design of new and expansion of existing network infrastructures requires improving the quality of service(QoS). Modeling probabilistic and time characteristics of telecommunication systems is an integral part of modern algorithms of administration of quality of service. At present, for the assessment of quality parameters except simulation models analytical models in the form of systems and queuing networks are widely used. Because of the limited mathematical tools of models of these classes the corresponding parameter estimation of parameters of quality of service are inadequate by definition. Especially concerning the models of telecommunication systems with packet transmission of multimedia real-time traffic.
