Measuring the Maturity of Open Source Software for Digital Libraries: a Case Study of DSpace

The assessment of maturity of software is an important area in the general software sector. The field of OSS also applies various models to measure software maturity. However, measuring maturity of OSS being used for several applications in libraries is an area left with no research so far. This study has attempted to fill the research gap. Measuring maturity of software contributes knowledge on its sustainability over the long term. Maturity of software is one of the factors that positively influence adoption. The investigator measured the maturity of DSpace software using Woods and Guliani‟s Open Source Maturity Model-2005. The present study is significant as it addresses the aspects of maturity of OSS for libraries and fills the research gap on the area. In this sense the study opens new avenues to the field of library and information science by providing an additional tool for librarians in the selection and adoption of OSS. Measuring maturity brings in-depth knowledge on an OSS which will contribute towards the perceived usefulness and perceived ease of use as explained in the Technology Acceptance Model theory.

Large-Size AlGaN/GaN HEMT Large-Signal Electrothermal Characterization and Modeling for Wireless Digital Communications

The rapid growth in high data rate communication systems has introduced new high spectral efficient modulation techniques and standards such as LTE-A (long term evolution-advanced) for 4G (4th generation) systems. These techniques have provided a broader bandwidth but introduced high peak-to-average power ratio (PAR) problem at the high power amplifier (HPA) level of the communication system base transceiver station (BTS). To avoid spectral spreading due to high PAR, stringent requirement on linearity is needed which brings the HPA to operate at large back-off power at the expense of power efficiency. Consequently, high power devices are fundamental in HPAs for high linearity and efficiency. Recent development in wide bandgap power devices, in particular AlGaN/GaN HEMT, has offered higher power level with superior linearity-efficiency trade-off in microwaves communication. For cost-effective HPA design to production cycle, rigorous computer aided design (CAD) AlGaN/GaN HEMT models are essential to reflect real response with increasing power level and channel temperature. Therefore, large-size AlGaN/GaN HEMT large-signal electrothermal modeling procedure is proposed. The HEMT structure analysis, characterization, data processing, model extraction and model implementation phases have been covered in this thesis including trapping and self-heating dispersion accounting for nonlinear drain current collapse. The small-signal model is extracted using the 22-element modeling procedure developed in our department. The intrinsic large-signal model is deeply investigated in conjunction with linearity prediction. The accuracy of the nonlinear drain current has been enhanced through several issues such as trapping and self-heating characterization. Also, the HEMT structure thermal profile has been investigated and corresponding thermal resistance has been extracted through thermal simulation and chuck-controlled temperature pulsed I(V) and static DC measurements. Higher-order equivalent thermal model is extracted and implemented in the HEMT large-signal model to accurately estimate instantaneous channel temperature. Moreover, trapping and self-heating transients has been characterized through transient measurements. The obtained time constants are represented by equivalent sub-circuits and integrated in the nonlinear drain current implementation to account for complex communication signals dynamic prediction. The obtained verification of this table-based large-size large-signal electrothermal model implementation has illustrated high accuracy in terms of output power, gain, efficiency and nonlinearity prediction with respect to standard large-signal test signals.

Estudio de prefactibilidad para determinar si genera rentabilidad financiera por encima de la tasa de oportunidad de la empresa, el montaje y operación de 40 Puntos Vive Digital en la ciudad de Bogotá. Teniendo en cuenta los estudios de soporte tales como: entorno, mercado, técnico, administrativo, legal, financiero, económico-social. Para llevar a cabo dicho objetivo, la empresa deberá evaluar la posibilidad de presentarse a la convocatoria que lidera el Ministerio de Tecnologías de Información y las Comunicaciones (TIC), en el marco del Plan Vive Digital a través del Programa Compartel que promueve la creación de 320 Puntos Vive Digital para el año 2012. Por esta razón, la empresa contrató un formulador para estructurar el proyecto y servir como soporte de un proceso para la toma de decisiones en el escenario real de participar en la convocatoria del proyecto de Puntos Vive Digital del Ministerio de Tecnologías de Información y las Comunicaciones (TIC). Luego de finalizar dicha investigación, resultó recomendable para la empresa, participar en el Programa Plan Vive Digital, particularmente en el proyecto de Puntos Vive Digital, luego de constatar que genera riqueza a la empresa, contribuye en su plan estratégico 2012-2014, especialmente en ampliar su portafolio de servicios TIC de manera rentable y finalmente, cuenta con la experiencia de ejecutar este tipo de proyectos debido a la gran trayectoria en el montaje y operación de puntos de acceso masivo a internet en la ciudad.

Ética hacker y propiedad intelectual: una nueva perspectiva para abordar la normatividad sobre derechos de autor en el espacio digital

En el presente texto se busca mostrar las capacidades explicativas que puede tener la conjunción entre las perspectivas de la ética hacker y la defensa de la propiedad intelectual para dar cuenta de las reacciones generalizadas de rechazo ante las normatividades de derechos de autor en el espacio digital. Así, se lleva a cabo un resumen de los principios de cada una de estas perspectivas dando cuenta de sus capacidades explicativas y características teóricas para, posteriormente, aplicarlas a la realidad empresarial, laboral y de opinión en el marco social contemporáneo. Cómo conclusión de este trabajo se logra observar que a pesar de que en principio ambas perspectivas podrían parecer contradictorias, existen aspectos comunes que permiten vislumbrar como un trabajo en conjunto permitiría generar normatividades que se acoplen a las realidades contemporáneas.

Cómics para videojuegos, industria cultural y digital.

Las Start-ups han se consideran el medio por el cual personas independientes puedan dar a conocer sus nuevas e innovadoras ideas. Estas nuevas ideas son las que hoy en día invaden el mundo de la tecnología, mueven el mercado y la inversión por parte de diferentes empresas. El auge de los smartphones y la tecnología que manejan, han permitido que diferentes Start-ups puedan sobresalir con sus ideas y poder mostrarlas el mercado. El éxito de este modelo de negocio ha permitido que haya más competencia y variabilidad en el mercado, de igual forma ha rompido con estereotipos que muchos profesionales han tenido por años. Estas pequeñas empresas a través de las aplicaciones móviles, o “Apps”, han hecho la vida del ser humano más simple dándole soluciones digitales en el teléfono celular o diferentes artefactos tecnológicos. La relación del hombre y la tecnología ha sido objeto de estudio para la antropología digital, pues el interactuar con el mundo tecnológico el ser humano ha cambiado su estilo de vida y comportamientos. Por otro lado, los medios que las industrias digitales ofrecen, han sido de gran ayuda para poder generar un mayor contacto, o empatía, con el ser humano. De esta manera muchas empresas acuden a estas ideas creativas para que sus productos puedan generar una mayor empatía con los consumidores y así haya fidelidad hacia éstos. Esta tesis buscará dar una solución a la empresa TTidh, para que pueda promocionar y dar a conocer al público, sus videojuegos en el formato de aplicaciones móviles. La solución a este problema se dará a través de un cómic el cual se hará con el videojuego Pesty Veggies. Este tendrá tres objetos de estudio principales. El Primero será el estudio de la antropología digital, las necesidades digitales y análogas. El segundo será analizar la historia de los cómics y cómo surgió su éxito. Finalmente, la realización del comic.
