Seminario para optar al título de Ingeniero Comercial, Mención Administración / El presente documento exhibe el proyecto de realización de un restaurante de comida rápida premium japonesa llamado The Gohan Bar. Ideado por tres alumnos de Ingeniería Comercial mención administración de la Universidad de Chile, The Gohan bar busca ser la solución para aquellos consumidores, principalmente ejecutivos, que buscan un producto altamente personalizable, rápido, variado y creativo. Dentro de las ventajas competitivas del restaurante, se encuentra el hecho de que el producto (Gohan), ya ha penetrado en nuestro país y se ha convertido en un producto popular y masivo. The Gohan Bar además de ofrecer un producto en un formato innovador que no ha sido desarrollado por ningún restaurant (made-to-order express), busca entregar una experiencia integral basada en los principios de sustentabilidad y especial preocupación tanto en el proceso de selección de insumos, como en el impacto medioambiental a través de la incorporación de prácticas de reciclaje, utilización de materiales sustentables, entre otros. Por otro lado, el formato de bowls reutilizables (desarrollado en detalle en el desarrollo de la presente tesis) entrega a The Gohan Bar una excelente alternativa para fidelizar a su clientela de forma creativa y novedosa, la cual ha demostrado tener éxito en países como Estados Unidos, particularmente en el popular restaurante de ensaladas a la orden, Just Salad. El público objetivo de The Gohan Bar son ejecutivos jóvenes, con mediano a alto poder adquisitivo que trabajan en áreas principalmente comerciales, tales como el Golf. Si bien inicialmente se abrirá únicamente un local en dicho barrio, el proyecto busca convertirse en un proyecto masivo a través del sistema de franquicia, una vez que la marca se haya popularizado y enraizado en los hábitos alimenticios de los ejecutivos. El restaurant ofrecerá sus productos mediante dos formatos principalmente; el primero, bastante similar al sistema utilizado por la cadena de sandwiches made - to - order Subway, que consta de una barra en la cual los consumidores pueden armar el producto en base a frescos ingredientes que se encontrarán en exhibición a su gusto. El segundo formato en el que se ofrecerán los productos será express, denominado Touch’n Gohan y será vendido por máquinas dispensadoras touch, cuyo modelo fue desarrollado y ha logrado gran éxito comercial gracias a la empresa Holandesa FEBO. El valor promedio de un almuerzo en el restaurante oscila entre $5.000 y $6.500 pesos chilenos, y se busca un crecimiento explosivo durante los meses de introducción de la marca. En cuanto a la competencia, en esta fase no conforma una amenaza relevante ya que no existen a la fecha restaurantes que ofrezcan un producto similar al nuestro. Los gohans que se venden hoy en día en el país, se ofrecen generalmente en restaurantes de Sushi, y el tiempo de pedido suele demorar entre 15 a 30 minutos, además de no ofrecer las opciones de personalización ofrecidas por el presente proyecto. El producto se encuentra completamente desarrollado, restando actividades relativas a la construcción e iniciación de operaciones comerciales y reclutamiento de personal. Durante el funcionamiento del negocio será fundamental cuidar ciertos aspectos que conforman parte de la esencia del restaurant, tales como la creación y mantención de una imagen corporativa consistente, la capacitación y control constante de staff con el fin de asegurar atención al cliente de excelencia, así como la constante preocupación por incorporar elementos distintivos relacionados a la sustentabilidad y realización de operaciones comerciales con valor agregado, las cuales permitirán también crear campañas de marketing en las cuales se informe a nuestros clientes del orgullo que tenemos como restaurant, en la forma en la que escogemos nuestros ingredientes, preparamos nuestros gohan y nos hacemos cargo de los deshechos de The Gohan Bar. Otro factor relevante es el destinar tiempo y recursos en investigar tendencias del mercado gourmet y alimenticio, con el fin de posicionarnos en el tiempo como un restaurante de vanguardia y acorde al avance de tendencias tanto en sabores como imagen corporativa. Los invitamos a encantarse con el proyecto de la misma forma en la que nosotros nos hemos involucrado. Si bien nos encontramos muy optimistas en cuanto a los resultados económicos a obtener, lo que más nos ha inspira e impulsa es el hecho de tener claridad en que nuestros productos se seleccionarán y confeccionarán con distintiva atención al detalle y preocupación por agregar valor disminuyendo el impacto en nuestro planeta e impulsando la preferencia por productos que han sido producidos en nuestro país, por compatriotas Chilenos.

Currently, logistics is considered as one of the most dynamic sector and therefore it should be given considerable attention. With the current trend of the globalization, we can expect increasing tendency in the near future. Logistics as we know it today has been really an indispensable part of our daily lives. All these activities are covered by logistics processes, without which we cannot imagine the modern life as we know it today.The aim of my thesis is to describe and analyze services and product lines of DHL Express (Czech Republic) Ltd. I chose this topic because I worked in the company and therefore I know the internal conditions and thus can approach the issue comprehensively. The main focus is on description and assessment of existing services DHL Express in the theoretical part. In the practical part, I would like to analyze the new, introducing the services that DHL recently applied or only will implement in the near future. It is for example the Service Point or modern service on petrol station related with expenditure shipments. Outputs of my final project should be beneficial also for the company itself. They are recommendations which services are most used and on the other hand should be turn down or improved. The arguments and opinions in the thesis are supported also by the questionnaire.

From several points of view, freeways are a desirable urban technology. Not only do they provide high levels of mobility and traffic capacity, but their safety, fuel consumption and pollution-generation characteristics are the best available. Even in terms of noise generation and its impact on the urban environment, it is desirable to have maximum traffic diversion from surface streets to appropriately designed freeway facilities. Yet freeway development is not without its costs. Opposition has grown, and now assumes a dominant position, politically, throughout much of North America, because the construction of freeways has often entailed severe disruptions of settled communities. These disruptions are referred to collectively as "community impact". The problem of this paper is the design and performance evaluation of a limited form of freeway, a form which attempts to minimize community impact. To the extent that such a form is possible, the environmental and other advantages of continuous-flow operation of motor vehicles will be available at lower social cost. The study begins by identifying the impacts to be avoided. "Residential displacement", "visual intrusion", JL'noise impact" and "traffic focal points and 'dumping' of traffic" are potential impacts of freeway construction and operation. Because of the nature of the designs being considered, "difficulties of local access and parking" is included for examination, as is the satisfactoriness of the highway driving environment. The general conclusions of the study are as follows. (1) Residential displacement would be limited to the removal of one house on the 3»2 mile test route. (2) The highway would not be visually intrusive since it would be completely hidden from view. (3) At maximum noise generation, one of the test designs would produce no impact at nearby buildings and from "marginal" to "definite" impact at sidewalks adjacent to the facility; the other design would produce a "marginal" impact at the building facade and a "definite" impact at the sidewalk, (k) There would be no dumping of traffic in the study area. (The facility performs only the line-haul function with no collector/distributor element.) (5) Local access and parking could be assured, but would require the upgrading of rear lanes the parking of vehicles on private property. (6) The visual quality of the highway driving environment, though less than ideal, is judged to be satisfactory. Unfortunately the less effective of the designs from a noise containment point of view is probably the most desirable aesthetically. (7) Total development cost of each of the "minimal impact" designs approximates the total dollar costs of conventional inner-city freeways. It is concluded that minimal impact freeways appear to be feasible, both technically and economically, for the line-haul function across inner suburbs. Since it now appears possible to construct limited forms of freeway with little adverse community effect, freeways should no longer be considered a non-option for built-up-areas. / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

Adaptive Cruise Control (ACC) vehicles have a longer reaction time, and the on-board sensors have a limited detection range that adversely affects the freeway bottleneck capacity. These limitations can cause small speed fluctuations into larger stop-and-go waves at typical freeway bottlenecks. Microsimulation results revealed that flow instability increases with the increase in ACC market penetration for a single lane freeway. The ACC car following model was developed for higher speed ranges only; thus, it could not capture rapid deceleration to lower speeds, let alone complete stops. The algorithm applies collision avoidance and brake relatively late in those instances, which leads to vehicles clustered closer together when at complete stops (or lower speeds). Therefore, the jam density increases with ACC market penetration. Simulation results also represented that no change in capacity was observed with the introduction of ACC vehicles on a freeway without diverging off-ramp and merging on-ramp demand compared to manually driven vehicles. The result is owed to the fact that lane changes and disturbances are not prominent without merging and diverging sections. However, the situation aggravates more for ACC vehicles when there is diverging off-ramp demand and merging on-ramp demand. The effect becomes severe with the increase of ACC market penetration. The field experiments for the fundamental characteristics of traffic flow showed that maximum capacity can be achieved when all the vehicles are operating in ACC mode. However, that maximum flow is unstable, and a minor speed variation can cause severe capacity drop. The jam density is also more in all ACC scenario that might result in rapid queue propagation as the wave speed is larger compared to the mixed driving scenario. / Includes bibliography. / Thesis (MS)--Florida Atlantic University, 2021. / FAU Electronic Theses and Dissertations Collection

Developments in high resolution traffic sensors over the past decades are providing a wealth of empirical speed-flow data. Travel demand models use speed-flow relationships to assign traffic flows to network links. However, speed-flow relationships have not been revalidated against new detailed traffic sensor data. Therefore, it is necessary to revisit speed-flow relationships based on actual measured conditions on network links rather than assuming constant speed-flow relationships over entire highway network systems. Speed-flow relationships have been particularly difficult to calibrate and estimate when traffic volumes approach capacity, i.e. when the v/c ratio approaches one. This thesis empirically evaluates the speed-flow relationships for v/c < 1 using field data. For congested conditions (v/c > 1) a theoretical approach is taken. A new methodology to determine the distribution of the activation of bottlenecks, bottleneck duration, and bottleneck deactivation is proposed. This thesis is a new contribution to understand the stochastic nature of freeway capacity as well as bottleneck duration, activation, and deactivation. Unlike previous research efforts, this thesis studies speed-flow relationships at the lane level and later presents a method to estimate speed-flow relationships at the link level.

Every one who has driven on a freeway has observed the phenomenon of lanechanging. This phenomenon is, of course, caused by the desire of most of the drivers not to be in a slow-moving lane. Therefore, the average driver who finds himself in such a lane moves into a neighboring faster lane, usually after a certain time-lag. This time-lag depends on the dynamic characteristics of the vehicle, the availability of acceptable gaps, and the driver risk, which is the value the driver places on the probability of collision during a maneuver, i.e. the higher the perceived probability of collision, the higher the time-lag. Modelling of the lane-changing phenomenon has been the objective of many investigators in the past. As will be shown later in this study, lane-changing is a very important component in highway traffic flow. In this study, a mathematical model to describe the lane-changing behaviour is suggested based on the lane-changing hypothesis that whenever there is a lane-changing maneuver, the average speed of the neighboring lane is faster than the average speed of the current lane. A set of data has been collected by a methodology which involves aerial photographic technique. The collected data are then used to test the validity of the lanechanging hypothesis, to calibrate and validate an existing lane-changing model, and to develop a gap acceptance function for freeway lane-changing maneuvers. / Master of Science

O foco central desse trabalho é a utilização e aprimoramento de um framework Peripheral Component Interconnect Express (PCI Express®) para a comunicação de dados em um Espectrômetro Digital de Ressonância Magnética (Digital Magnetic Resonance Spectrometer &#8211; DMRS) utilizando o conceito de Field-Programmable Gate Array (FPGA). Esse trabalho foi desenvolvido para servir como base de comunicação para o Espectrômetro Digital de Ressonância Magnética do Centro de Imagens e Espectroscopia in vivo por Ressonância Magnética (CIERMag) devido ao requerimento de altas taxas de transferência dos dados adquiridos. A integração dessa nova comunicação, entre o software e o hardware do espectrômetro, mantém compatibilidade com as interfaces já existentes possibilitando a execução de todas as sequências desenvolvidas sem nenhuma alteração. A incorporação da comunicação PCI Express provê uma solução com um número menor de etapas por transferência em comparação com a comunicação Ethernet. Com isso é possível aumentar o desempenho do sistema e obter taxas de transferência mais elevadas. Para isso, foram feitas mudanças no hardware de forma a torná-lo mais eficiente, reduzindo o número de ciclos de clock por operação e também a quantidade de lógica sintetizada. Além disso, a latência do software durante as transferências também foi reduzida através da utilização de interrupções Message Signaled Interrupt (MSI) e do método Scatter and Gather usado para reduzir a quantidade de cópias de dados na memória principal do computador. Dessa forma, obteve-se, como resultados reais, uma taxa de transferência efetiva (throughput) de 97% do valor máximo da banda possível do barramento PCI Express. / The central focus of this work is the implementation and use of a Peripheral Component Interconnect Express (PCI Express®) framework for data communication on a Digital Magnetic Resonance Spectrometer (DMRS) using the concept of Field-Programmable Gate Array (FPGA). This work is being developed to serve as a communication basis for the magnetic resonance Digital Spectrometer of the Centro de Imagens e Espectroscopia in vivo por Ressonância Magnética (CIERMag) due to demand of high transfer rates of acquired data. The integration of this new communication, between spectrometer software and hardware, keeps compatibility with existing interfaces, making it possible to execute all developed magnetic resonance sequences without any change. The incorporation of PCI Express communication provides solution with a lower number of steps per transfer when compared to Ethernet communication. By this means it\'s possible to increase system performance and, as result, have higher transfer rates. To accomplish that, the number of clock cycles per operation was reduced, so was the synthesized logic. Furthermore, software latency for data transfer was also reduced consequence of MSI interruption implementation and the use of Scatter and Gather method to remove data movement across the computer main memory. Therefore, it was obtained, as measured real result, a throughput value of 97% the theoretical maximum value for the hardware.
