Spacecraft thermal design is an inverse problem that requires one to determine the choice of surface properties that yield a desired temperature distribution within a satellite. The current techniques for spacecraft thermal design are very much in the frame of trial and error. The goal of this work is to move away from that procedure, and have the thermal design solely dependent on heat transfer parameters. It will be shown that the only relevant parameters to attain this are ones which pertain to radiation. In particular, these parameters are absorptivity and emissivity. We intend to utilize an optimal/analytical approach, and obtain a solution via optimization. As mentioned in the motivation, having a purely passive thermal system will greatly reduce costs, and our optimization solution will enable that. This topic involves hea...
We present a model to support the design, analysis, and comparison of games through the use of game design patterns, descriptions of reoccurring interaction relevant to game play. The model consists of a structural framework to describe the components of games, and patterns of interaction that describes how components are used by players (or a computer) to affect various aspects of the game play. Focusing on the patterns and identified methods for using them, we describe the development of the model and how we are currently working to enlarge and validate the collection of patterns.
The rise of mobile platforms and the Web has created a market where software is now funded by advertisements, subscriptions and in-app purchases. This software is designed with retention in mind, motivating users to return to the application again and again.However, developers struggle to understand exactly how to motivate users. This lack of understanding has given rise to the easy answers of 'gamification' and 'social,' without providing the foundational psychological knowledge developers need to truly understand their users' needs. New frameworks are required to bridge this knowledge gap.This dissertation presents one such framework, a library of twenty-seven motivational design patterns, under the categories of gameful, social, interface and information. Theories and experimental results from motivational psychology, behavioral ps...
The task of the lighting designer has become very complex, involving thousands of choices for fixture types and hundreds of possible lamps. The designer who can consider the most combinations of these items guarantees each client the optimal lighting conditions and the best energy efficiency. This kind of professional service, however, is not available from the software design programs presently on the market. These programs generally let the designer analyze one room at a time, while providing perhaps three possible fixtures to choose from. Additional choices can be accessed from the software’s data base, though at considerable expense in time and patience. This is a real hindrance when designing for a complex structure such as a hospital, which has many spaces with different task-specific lighting standards. The author was challenge...
This article discusses multicell CDMA network design.
Human-centered design has emerged as an important strategy in product and service design and development, as it has become recognized that understanding user needs is critical to product success. That understanding typically emerges through design research: the systematic study of the attitudes, behaviors, and desires of potential users and customers. The impact of design research depends on its visibility and credibility to decision-makers. However, challenges to this visibility and credibility present themselves when there are organizational separations between those conducting the research and those involved in the product development. A specific team or company may conduct design research, and then pass the results of that process to another team of industrial designers or engineers. Since the second team often neither conducts r...
The emergence of computation in design is an ongoing evolution, rather than a technological revolution. Contemporary digital tools have influenced the image of architecture, as object, as shelter, and as icon – but digital design has yet to change our understanding of architecture, or alter its larger impact on the built world around us. Although design tools, including computation, and digital production are now well intertwined in architectural methodology, additional innovations are emerging which have potential to bring the true value of computation into design methods. If these tools are widely implemented there is potential for this digital evolution to become a technological revolution in architecture.
Both, the logistics and insurance companies rely on software intensive systems and IT-infrastructure to run their core business operational. In recent years IT-improvements have resulted e.g. in better tracking and tracing capabilities for the whole logistics industry. Designing an interface in this case between the logistics and insurance value chain further enhances visibility and transparency on transportation. Though, the design of a large collaborative service infrastructure is a complex task. In this paper, we investigate whether design science supports this. The research follows design science guidelines creating a message hub based on sensor telematics technologies, which physically links the two value chains. The described IT-artefact enables logistics and insurance companies to improve their respective products and solutions ...
The purpose of this thesis is to provide research, supporting paperwork, and production photographs that document the scenic design for the University of Maryland-College Park, Department of Theatre's <italic>Gilgamesh</italic>. This thesis contains the following: research images collected to develop and visually communicate ideas about color, texture, scale, and mood to the production team; preliminary sketches and photographs of the ¼" scale model, visual tools used to convey the idea of the scenic design; a full set of drafting plates and paint elevations used to communicate the look of each scenic element to the technical director and paint charge; a unit list providing detailed information about each element of the scenic design; a props list detailing each prop used in the production; and props / paint research images, used to ...
The following thesis documents the costume design process and execution for the production of Rent by Jonathan Larson. Supporting documents included are research, renderings, fabric samples, fitting photographs, and production photos. The Production presented in this paper was produced October 21,2011 at the University of Maryland in the Ina and Jack Kay Theater a six hundred and fifty seat proscenium theatre. Alan Mingo Jr. directed the production, the set was designed by Douglas Clarke, the lighting was designed by Andrew Dorman, the projection design was designed by Jedediah Roe, and the sound was designed by Neil McFadden.
