Cultura alimentar : cartografias rurais em tempos de aceleração

Althaus, Eduardo Cristiano January 2018 (has links)
Fundamentada na afirmativa de Mássimo Montanari, de comida como cultura, esta dissertação pretende acompanhar através de uma cartografia rural, as transformações das paisagens culturais alimentares na cidade de Tio Hugo/RS e seu entorno. O trabalho é apresentado em dois tempos, o primeiro deles sob a metáfora de um mise-en-place, onde são pré-preparados os conceitos fundantes da pesquisa, bem como as estratégias utilizadas em seu modo de preparo. O segundo tempo é composto pela incursão no território pesquisado, pelas narrativas de mulheres colonas e suas famílias e, também, pela apresentação das análises empreendidas pelo cartógrafo, dentro do que se circunscreve como campo dos Estudos Culturais em Educação. A ênfase desse estudo está direcionada para algumas transformações culturais das técnicas utilizadas nas preparações de alimentos, em seus modos de preparo, nas escolhas dos ingredientes, do tempo destinado ao fazer culinário, dos saberes transmitidos, dos processos de urbanização e industrialização do meio rural. O eixo do trabalho são os deslocamentos espaço-temporais e as vicissitudes da cultura. O desfecho da pesquisa busca problematizar, a partir desses eixos, como vem se produzindo uma percepção acelerada do tempo, correlacionada a alguns aspectos como o uso de tecnologias, ao fenômeno da globalização, das relações entre produção-consumo, do terreno que emerge como gastronomia, da memória e da invenção das tradições. / Based on Massimo Montanari's view of food as culture this thesis aims to follow through a rural cartography the changes of food culturallandscapes in the city of Tio Hugo/RS and its surroundings. This dissertation is presented in two stages, the first of them shows it through a mise-en-place metaphor in which the basic concepts for this research are pre-prepared in addition to the strategies used for such process. The second moment is comprised by the incursion in the studied territory through the narrative of women settlers and their families as well as composed by showing the analysis made by the cartographer in what is circumscribed in the field of Cultural Studies in Education. The focus of this paper is directed to some cultural transformations in the techniques used in the food preparation, in the selection of ingredients, in the time spent in the act of cooking, in knowledges passed on, in the urbanisation and industrialisation process in the rural area. This essay core is the space-time journeys and the cultural vicissitudes. The gol of this work is to problematize through these grounds how a fast-forward perception of time has been created, correlated to some aspects of use of technologies, to the globalisation phenomena, to te relations between production and consumption, to the territory that emerges as gastronomy, to the memory and the creation of traditions.

Modelagem do problema de escalonamento de veículos com múltiplas garagens usando rede tempo-espaço : grandes instâncias e frota heterogênea

Guedes, Pablo Cristini January 2014 (has links)
O problema de escalonamento de veículos com múltiplas garagens (MDVSP, do inglês Multi-Depot Vehicle Scheduling Problem) é um problema clássico de logística e transportes. O MDVSP também é a base para a solução de vários problemas correlatos, tais como o problema de escalonamento de veículos em tempo-real e soluções integradas com o escalonamento de veículos, tais como o escalonamento da tripulação e otimização da tabela de horários. Desta forma, aprimorar a solução deste problema pode ser considerado de grande relevância, a qual permitirá resolver grandes instâncias reais de forma eficiente, bem como permitir a solução de problemas correlatos. O objetivo desta dissertação é verificar a aplicabilidade da utilização da rede tempo-espaço e do método de geração de colunas modificado proposto, para a solução deste problema, e de sua variante com frota heterogênea, considerando grandes instâncias. Diversos testes foram realizados utilizando o gerador de instâncias aleatórias com base na distribuição de demandas proposto. Grandes instâncias, envolvendo milhares de viagens (entre 500-10.000) e dezenas de garagens (4-128) são resolvidas em tempos razoáveis. / The multiple-depot vehicle-scheduling problem (MDVSP) is a classic logistic and transportation problem. The MDVSP is also a subproblem for solving various related problems, such as the real time vehicle scheduling problem, disruption management; and integrated problems such as the vehicle and crew scheduling problems. Although several mathematical and solution method have been developed in the literature, large instances (involving thousands of trips and several depots) are still difficult to solve in a reasonable time. The objective of this research work is to verify the applicability of the use of the space-time network towards obtaining good solutions for large instances in short time. Time-space network was suggested by Kliewer et al (2006), and it is positioned with respect to two-dimensional axes, one representing time and the other one space or stations. The arcs represent deadheading movements; and waiting periods in the same station. Solution methods for the MDVS combining time space with integer linear programming solvers and column generation were developed. Extensive testing was carried out using random generated instances, based on demands distribution. Large instances, involving thousands of trips (between 1,000-10,000) and dozen (4-64) depots, are solved in reasonable times.

Time, space and multiplicity in China's harmonious world

Nordin, Astrid January 2013 (has links)
Multiplicity is a key challenge and opportunity of world politics, yet scholars continue to struggle to do it justice. One way of reducing the challenge multiple times and spaces present us with has been to organise them allochronically, to align spatial difference in temporal sequence. The effect is a story where others are not different, they are just behind. Scholars have criticised this thinking as it appears in “Western thought”. In recent years, suggestions have emerged that Chinese thought may offer an alternative that escapes allochronic thinking, most notably through the foreign policy-driven concept “harmonious world”. Scholars have studied this term with the aim of finding out its true meaning. This thesis asks instead what “harmony” – and more specifically “harmonious world” – does when it is deployed in contemporary China. It traces the concept across several contexts: the policy documents and speeches that launched it as an official term; the academic literatures that asked what a harmonious world might look like; the propaganda at Expo 2010 Shanghai China that aimed to illustrate it; and the online spoofing culture egao that was used to criticise, resist and avoid “harmonisation”.The key claim of this thesis is that “harmonious world”, as articulated in the contexts examined here, has not taken place, is not taking place and will not take place. Ways of thinking about time, space and multiplicity in China’s relation to the world, and particularly “harmonious world”, repeat the allochronising logic recognisable from “Western” discourses, which disallows the openness of the future and reduces the possibilities of harmony and of the political. As an effect of its excessive proliferation harmony disappears as an imagined metaphysical possibility . The harmonious system is not based on co-operation or non co-operation, but works according to what this thesis calls an onco-operative logic: the quasi-suicidal logic of cancer and the (auto)immune. Ultimately, the aim and most important contribution of this thesis is to bring the onco-operative uncertainty of the political back into the harmonious world concept in order to elucidate the negotiation of danger and necessity of multiplicity.

Problemáticas del espacio en la narrativa hispanoamericana contemporánea (1990-2010)

Alvarez, Moira January 2015 (has links)
My dissertation, “Problemáticas del espacio en la narrativa hispanoamericana contemporánea (1990-2010)” [Problematics of Space in Contemporary Spanish American Narrative (1990-2010)], focuses on the concept of space and its articulations in a diverse corpus of written and visual narratives by contemporary Latin American authors. The problematics of spaciality are analyzed within the specific time period encompassing the last decade of the 20th century and the first decade of the 21st century, a period in which space has emerged as an important category for understanding the present. The “spatial turn”, proposed and analyzed by Michel Foucault, David Harvey, and Edward Soja, assumes that space has become a more relevant analytical category than time, due to the emergence of new technologies and media, new forms of capital flow, and because of the preeminence of the image in contemporary times. Following Henri Lefebvre’s foundational proposal, I understand space in relation to social formation and as a product of human practices rather than as an a priori category or an abstract geometrical notion independent of subjectivity and human agency. Within this framework, the problematics of space are analyzed in a corpus that includes the novels Amuleto (1999) by Roberto Bolaño, La virgen de los sicarios (1994) by Fernando Vallejo, and El asco. Thomas Bernhard en San Salvador (1997) by Horacio Castellanos Moya, and two films, Los rubios (2003) directed by Albertina Carri, and La teta asustada (2009) by Claudia Llosa. The first chapter of the dissertation lays out the theoretical framework of the concept of space and the specific socio-economical characteristics of the studied time period. The second chapter analyzes the enclosed space of Amuleto in the context of Mexico’s 1968 Tlatelolco Massacre, and proposes that a “space of the abyss” emerges with the death of a Latin American generation and the fall of the utopias in the 1960s. The third chapter compares and contrasts the films La teta asustada and Los rubios with respect to the theme of postmemory in the periods following the internal conflict in Peru and the military dictatorship in Argentina. The “space of postmemory” that arises in both films relates to the interplay between the absence/presence of the bodies of the parents – who lived the traumatic events – and the second generation that inherits the trauma. The fourth chapter examines the “spaces of escape” that emerge from La virgen de los sicarios and El asco as a possibility of escape for protagonists who face collapsed cities and states: Medellin after the death of Pablo Escobar, and San Salvador after the end of the Civil War. The three configurations of space that arise from the corpus – “space of the abyss”, “space of postmemory”, and “space of escape” – articulate crucial issues of contemporary Latin America such as the fall of modernizing utopias, trauma, postmemory, disenchantment, and the failure of the liberal state. They also bring to light three key features of contemporary spatiality: the individualization of spaces pointing to individualism as a necessary condition for new fluxes of capitalism; the reduction of diegetic spaces that relates to the concept of time-space compression proposed to account for the spatial changes of the studied period; and the appearance of spaces of refuge as a general response to the ephemeral conditions of the present. / Spanish

USING COOPERATIVE RESEARCH AND DEVELOPMENT AGREEMENTS (CRADA) TO REDUCE THE TRANSITION TO PRODUCTION RISK OF A MISSILE TELEMETRY SECTION

Kujiraoka, Scott R., Fielder, Russell G. 10 1900 (has links)
ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The Joint Advanced Missile Instrumentation (JAMI) Program’s main thrust has been the integration of Global Positioning System (GPS) tracking technology into the Department of Defense (DoD) Missile Test Ranges. This technology could be used for Time, Space, Position, and Information (TSPI), Flight Termination (FTS), or End Game Scoring purposes. However the Program’s main goal is to develop Proof-of-Concept components only. Transitioning Missile technology developed by the Government to Private Industry, so that it can be economically mass produced, has been quite a challenge. Traditionally, private industry has had to bid on proposals without much detailed information on how these components have been designed and fabricated. These unknown risks, Non-Recurring Engineering (NRE) and Missile Flight Qualification costs, routinely have significantly increased the price of these procurement contracts. In order so that the Fleet can economically utilize these components in the field, Cooperative Research and Development Agreements (CRADA) between the Government and Private Industry have been used to successfully transition Government developed technology to mass production. They can eliminate the NRE and flight qualification costs to provide for an economical and low risk method of providing the Fleet with the latest advances in GPS Tracking Technology. This paper will discuss how this is currently being accomplished in the development of a conformal wraparound instrumentation antenna for a five-inch diameter Missile Telemetry (TM) Section.

TRANSPORTABLE RANGE AUGMENTATION AND CONTROL SYSTEMS FOR MULTIPLE SHOT ENGAGEMENTS

Glenn, Tom, Chavez, Tomas, Toole, Michael T., Markwardt, Jack 11 1900 (has links)
International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / The Ballistic Missile Defense Organization (BMDO) is developing new Theater Missile Defense (TMD) weapon systems to defend against the rapidly expanding ballistic missile threat. The tactical ballistic missile threats include systems with range capabilities greater than 1000 kilometers. The development and testing of systems such as the Patriot Advanced Capability 3 (PAC-3), the Theater High Altitude Area Defense (THAAD), Navy Area Defense, and the System Integration Tests (SIT) to address the interoperability of this family of systems, will require the development of the Transportable Range Augmentation and Control System for Multiple Shot Engagements (TRACS - MSE). Congress has mandated that these systems be tested in multiple simultaneous engagements. These systems will be tested at several ranges to meet all the developmental and operational testers' needs. Potential range locations include White Sands Missile Range (WSMR), Kwajalein Missile Range (KMR), the Pacific Missile Range Facility (PMRF) and the Gulf Range at Eglin Air Force Base. Due to the long distances separating the target launch site and the interceptor site, the TRACS - MSE will be required at multiple sites for each range used. To be cost effective, transportable systems should be developed to augment existing capabilities. Advances in Global Positioning System (GPS) technology and high data rate receivers make telemetry based solutions attractive. This article will address the requirements for range safety, for Time, Space, Position Information (TSPI) collection and processing requirements to support a TRACS - MSE capability.
