Imagen de apoyo de UMTS Capacity simulation study (carried out at Vodafone Netherlands)

Por: Andrés Felipe Cosme Hurtado | Fecha: 2003

The purpose of this report is to investigate the performance, measured in terms of Key Performance Indicators (KPIs) of a UMTS radio network (UTRAN) under different traffic and mobility scenarios and develop general guidelines for dimensioning the UMTS network optimally. In this work, simulations are performed using Wines tool, which is a dynamic simulator that models all the radio-resource management functionality of the UTRAN. Two main series of experiments have been performed. In the first series, the distribution of the traffic is homogeneous and the main purpose is to find capacity figures when increasing the traffic density of one of the four possible defined services (WWW, FTP, voice and video-call) and also with a given traffic mix involving all services together. Two mobility profiles are used (pedestrian and vehicular). In the second series of experiments, a more realistic scenario, based on detailed geographical characteristics relevant for signal propagation, and traffic densities based on traffic maps (non homogeneous scenario), has been simulated. The purpose was to analyze the possible differences in capacity between the “ideal” model and the more “realistic” model. For the single-service scenario analysis, circuit-switched services (speech and video-call), it can be observed that the capacity is mainly uplink-limited. The corresponding results for the packet-switched services (FTP, WEB) have shown that capacity is mostly downlink-limited, as it was expected due to the more asymmetrical data rates in the downlink compared to the uplink for both services. For the service mix analysis in both scenarios (homogeneous and non homogeneous) it was found that the capacity is mostly downlink-limited (i.e. the downlink power target level is exceeded before the uplink load target level).

Imagen de apoyo de Conflict and disaster internally displaced persons (IDPs) in Colombia: Different labels, different rights? = Diferenciación entre Desplazados y Damnificados en Colombia; impacto de los rótulos en la protección de sus derechos

Por: Diego Andrés Hakspiel Bohórquez | Fecha: 2014

This dissertation critically examines the differentiation of Conflict IDPs (Desplazados) and Disaster IDPs (Damnificados) in Colombia, and the impact of label differentiation in the protection of their rights. The results presented in this study come entirely from a desk-based research, and will therefore focus on protection at a policy level. Based on Kälin’s Protection Cycle, this paper demonstrates how protection for both types of IDPs in Colombia is dealt with regardless of their label (prevention, assistance, and long term development), but discusses some of the remaining protection gaps.

Imagen de apoyo de Effets de la temperature de paroi sur la reponse de la flamme a des oscillations acoustiques

Por: Daniel Augusto Mejía Mejía | Fecha: 2014

Combustion instabilities, induced by the resonant coupling of acoustics and combustion occur in many practical systems such as domestic boilers, gas turbine and rocket engines. They produce pressure and heat release fluctuations that in some extreme cases can provoke mechanical failure or catastrophic damage. These phenomena have been extensively studied in the past, and the basic driving and coupling mechanisms have already been identified. However, it is well known that most systems behave differently at cold start and in the permanent regime and the coupling between the temperature of the solid material and combustion instabilities still remains unclear. The aim of this thesis is to study this mechanism. This work presents an experimental investigation of combustion instabilities for a laminar premixed flame stabilized on a slot burner with controlled wall temperature. For certain operating conditions, the system exhibits a combustion instability locked on the Helmholtz mode of the burner. It is shown that this instability can be controlled and even suppressed by changing solely the temperature of the burner rim. A linear stability analysis is used to identify the parameters playing a role in the resonant coupling and retrieves the features observed experimentally. Detailed experimental studies of the different elementary processes involved in the thermo-acoustic coupling are used to evaluate the sensitivity of these parameters to the wall temperature. Finally a theoretical model of unsteady heat transfer from the flame root to the burner-rim and detailed experimental measurements permit to establish the physical mechanism for the temperature dependance on the flame response.

Imagen de apoyo de Increasing value in architectural design by learning from different design disciplines and the use of value and design management

Por: Elias Jose Gómez Osorio | Fecha: 2014

The architectural design process is a negotiation between a problem and a solution through activities of analysis, synthesis and evaluation, it is characterised by being complex, with neither established nor mandatory patterns and methodologies. Design is an activity that involves constant and intensive decision-making processes in which designers, clients and users exchange knowledge and information in order to develop a solution for a given problem. However, these solutions do not always bring benefits to the client, causing dissatisfaction and creating problems for both clients and designers. These problems are mostly caused by the gaps between expectation and realisation on behalf of the client, often streaming from a lack of mutual knowledge between client and designer. Design and value management is a series of activities that can help designers to monitor, control and channel creativity in order to generate accurate, precise and valuable solutions for their client’s need. However, other design disciplines such as graphic and product design have different and valuable skills and methodologies that can contribute to this aim, helping architects to create proposals that will deliver longlasting benefits for both clients and end-users.

Imagen de apoyo de Three Stories Toward Creation Thesis Report = Tres Historias para la Creación

Por: Rodrigo Gómez Claros | Fecha: 2002

Desde la fantasía y la magia de la creación indígena hasta la derrota del conquistador como resultado de la ambición y la destrucción, son algunos de los elementos que se combinan para ofrecer un nuevo comienzo a lo que hoy se llama Cultura Latinoamericana. Con el juego de formas, colores y sonido se produce un pieza en la que se busca el regreso a una identidad propia. Principales objetivos: Presentar tres escenarios de la civilización latinoamericana a través del uso de símbolos precolombinos, elementos históricos, el formato de cuento y la animación como medio de crítica política y social en contra de la discriminación cultural en Norte América. Entender el concepto de cultura como un evento cíclico de tesis, antitesis y síntesis. Crear una interpretación personal sobre lo que es la cultura en Latino América. Comentario Técnico: Tres historias para la creación es una producción bi y tridimensional que utiliza los programas de animación Maya y After effects como fuente principal para generar imágenes en continua transformación explorando el uso de máscaras de vectores y cámaras múltiples en el mismo cuadro. También explora el juego con el área de encuadre como un elemento variable que forma parte de la historia. Programas utilizados: Alias Wavefront Maya 3.0 Sensable Technologies Freeform 4.0 Adobe Photoshop 6.0 Adobe After effects 5.0 Final Cut Pro 2.0 Sound Edit 16 2.0 Adobe Ilustrator 10.0 Fractal Painter 6.0
