Designed for disassembly: the push for a new approach to sports architecture in the 21st centuryMyers, Scott J. 08 June 2015 (has links)
The architecture of the sports stadium has evolved dramatically throughout its history. From the ancient gladiatorial arenas to the domes and retractable-roof ballparks of the 20th Century, the stadium has become an iconic and integral part of life, in our modern society. Through the globalization of sports and sporting events, such as the Olympics and World Cup, new and more exciting opportunities are being extended to those who, historically, have been without the resources or infrastructural means to support such endeavors. However, for all the excitement and optimism that accompanies the initial design and planning, the actual development of the necessary structures and support systems rarely provides the expected return on what, ultimately, becomes a staggering investment of time, money, and labor. In fact, operators have found it nearly impossible to provide for the continued operation, maintenance, and regular occupation of these facilities, thus resulting in an overwhelming burden on the local community.
It is the purpose of this thesis to provide a survey of architectural precedents from selected mega-events of the last 100 years, as well as a number of other contemporary stadium projects, in an effort to fully convey the magnitude and relevancy of this issue, to identify industry trends and practical models, and more definitively present the need for an alternative approach to design. Additionally, a proposal will be put in place for more of a focus on modularity and prefabrication, in order to transform the Olympic or World Cup stadium into a less permanent element within the urban landscape. It is the hope that the systemic issues, currently associated with hosting international sporting events, may be remedied through the architecture, and ultimate disassembly, of the 21st Century stadium. Ultimately, the goal is to reduce the negative impact of such undertakings, and to aid in the realization of the inherent potential for positive change therein.

Evaluation and Consequences Analysis of a Manual Shifter with Modular Design / Utvärdering och Konsekvensanalys av ett Manuellt växelreglage med Modulär DesignHilding, Amanda January 2014 (has links)
Subcontractors in the automotive industry, have a lot of pressure to bring down costs and to deliver products that are effective, optimized and qualitative. The main purpose of this study is to guide and conduct the first step in the project Standard Building Blocks with modular design, within the business area, manual shifter. The project is directly presented by Kongsberg Automotive, a well-known subcontractor of the automotive industry. The aim of the project is to develop a standard manual shifter with modular design containing standard building blocks. Five different components have been selected in the manual shifter for this study. In each component, there are several concepts on how to design that specific component. The target of the study is to evaluate and analyze the concepts and based on the results decide which of the concepts to be standard building blocks. The study identifies, evaluates and analyses the consequences of the project Standard Building Blocks for the chosen concepts. The results from the study show that some concepts have a greater tendency to form standard building blocks when compared to others. In the study it was proven that non-measurable values have the same significance as the measured values. The results also show that the most suitable concepts depends on the customers’ specifications. The consequence analysis presented many consequences of what an implementation of standard building blocks may imply, from the advantages to possible risk elements. Through the consequence analysis the studied company can become more prepared for the future. / Underleverantörerna inom fordonsindustrin har en stor press när det kommer till hålla nere kostnader och att leverera effektiva, optimerade och kvalitativa produkter.

Design and development of a modular robot for research usePaine, Nicholas Arden 30 November 2010 (has links)
This report summarizes the work performed for the design and development of the Proteus research robot. The Proteus design is motivated by the need for a modular, flexible, and usable autonomous robotic platform. To accomplish these goals, a modular hardware architecture coupled with low-power, high-computation processing is presented. The robot is subdivided into three layers: mobility, computation, and application. The interface between layers is characterized by well defined APIs and may be individually replaced to achieve different functionality. An efficient low-level event scheduler is described along with higher-level software algorithms for motion control and navigation. Experiments of Proteus robots are provided including field tests and collaboration with outside research institutions. / text

On the Modular Theory of von Neumann AlgebrasBoey, Edward January 2010 (has links)
The purpose of this thesis is to provide an exposition of the \textit{modular theory} of von Neumann algebras. The motivation of the theory is to classify and describe von Neumann algebras which do not admit a trace, and in particular, type III factors. We replace traces with weights, and for a von Neumann algebra $\mathcal{M}$ which admits a weight $\phi$, we show the existence of an automorphic action $\sigma^\phi:\mathbb{R}\rightarrow\text{Aut}(\mathcal{M})$. After showing the existence of these actions we can discuss the crossed product construction, which will then allow us to study the structure of the algebra.

Equations for modular curvesGalbraith, Steven D. January 1996 (has links)
The primary topic of this thesis is the construction of explicit projective equations for the modular curves $X_0(N)$. The techniques may also be used to obtain equations for $X_0^+(p)$ and, more generally, $X_0(N) / W_n$. The thesis contains a number of tables of results. In particular, equations are given for all curves $X_0(N)$ having genus $2 le g le 5$. Equations are also given for all $X_0^+(p)$ having genus 2 or 3, and for the genus 4 and 5 curves $X_0^+(p)$ when $p le 251$. The most successful tool used to obtain these equations is the canonical embedding, combined with the fact that the differentials on a modular curve correspond to the weight 2 cusp forms. A second method, designed specifically for hyperelliptic curves, is given. A method for obtaining equations using weight 1 theta series is also described. Heights of modular curves are studied and a discussion is given of the size of coefficients occurring in equations for $X_0(N)$. Finally, the explicit equations are used to study the rational points on $X_0^+(p)$. Exceptional rational points on $X_0^+(p)$ are exhibited for $p = 73,103,137$ and 191.

Development of a Mobile Modular Robotic System, R2TM3, for Enhanced Mobility in Unstructured EnvironmentsPhillips, Sean January 2012 (has links)
Limited mobility of mobile ground robots in highly unstructured environments is a problem that inhibits the use of such robots in applications with irregular terrain. Furthermore, applications with hazardous environments are good candidates for the use of robotics to reduce the risk of harm to people. Urban search and rescue (USAR) is an application where the environment is irregular, highly unstructured and hazardous to rescuers and survivors. Consequently, it is of interest to effectively use ground robots in applications such as USAR, by employing mobility enhancement techniques, which stem from the robot’s mechanical design. In this case, a robot may go over an obstacle rather than around it.
In this thesis the Reconfigurable Robot Team of Mobile Modules with Manipulators (R2TM3) is proposed as a solution to limited mobility in unstructured terrains, specifically aimed at USAR. In this work the conceptualization, mechatronic development, controls, implementation and testing of the system are given.
The R2TM3 employs a mobile modular system in which each module is highly functional: self mobile and capable of manipulation with a five degree of freedom (5-DOF) serial manipulator. The manipulator configuration, the docking system and cooperative strategy between the manipulators and track drives enable a system that can perform severe obstacle climbing and also remain highly
manoeuvrable. By utilizing modularity, the system may emulate that of a larger robot when the modules are docking to climb obstacles, but may also get into smaller confined spaces by using single robot modules. The use of the 5-DOF manipulator as the docking device allows for module docking that can cope with severe misalignments and offsets – a critical first step in cooperative obstacle management in rough terrain.
The system’s concept rationale is outlined, which has been formulated based on a literature review of mobility enhanced systems. Based on the concept, the realization of a low cost prototype is described in detail. Single robot and cooperative robot control methods are given and implemented. Finally, a variety of experiments are conducted with the concept prototype which shows that the
intended performance of the concept has been met: mobility enhancement and manoeuvrability.

The role of architectural knowledge in managerial decision making: an experimental discrete choice evaluation of the adoption of executional strategiesRichard, Pierre Jules, Strategy & Entrepreneurship, Australian School of Business, UNSW January 2009 (has links)
Managers have responsibility for implementing a firm??s executional strategy. An executional strategy is the selection of resources and capabilities and the arrangement of them into a supply chain that puts a firm??s espoused positioning into action (Porter, 1985). Executional strategies are selected to maximize economic rents. Firm resources (Barney, 1991) and the arrangement of supply chains (Chandler, 1962; 1990) are important to rent generation. In turn, the potential arrangement of activities into a supply chain is determined by a firm??s depth of architectural knowledge; this is knowledge of how supply chain elements can be linked (Henderson and Clark, 1990). The study provides a simultaneous test of the impact of resources and supply chain arrangements on the selection of executional strategies. The theoretical model is tested through a discrete choice experiment (Louviere et al., 2000). Findings suggest that resources and cost advantages dominate management decision-making with competition also an influence. Importantly, findings for a sub-sample of subjects whose firms are most impacted by Information technology (IT), confirms that architectural knowledge does play a role in the selection of executional strategies. These ??engaged?? subjects were significantly more experienced with the subject matter and more confident about their responses. These engaged subjects utilized architectural knowledge to select strategies that leveraged their resources more widely and to minimize the influence of transaction costs on their strategic choices.
