AHS Maglev System Architecture
… a vision was presented of an Automated Highway System developed under a contract naming Virginia Tech one of the three ITS Research Centers of Excellence in the United States by the Federal Highway Administration. The AHS envisioned would consist of a guideway constructed in the rights-of-way of …

System architecture metrics: an evaluation
… seeks to address these problems by proposing a systematic method for the development and evaluation of software metrics. The method is a goal directed, combination of formal modelling techniques, and empirical ealiat%or. The met\io s applied to the problem of developing metrics to evaluate …

The exokernel operating system architecture
On traditional operating systems only trusted software such as privileged servers or the kernel can manage resources. This thesis proposes a new approach, the exokernel architecture, which makes resource management unprivileged but safe by separating management from protection: an exokernel …

System architecture evaluation by single metric
System architecture is driven by numerous upstream influences. Regulations, market forces, cultural biases, and a variety of other influences can significantly affect whether architecture is successful or not. To be successful the architect must include upstream influences in the design. Few if any …

Complexity measures for system architecture models
… groundwork for measuring the complexity of systems architecture models. We propose a set of complexity measures, which are usable with models defined using the Object-Process Model (OPM). In order to do this, we introduce a new concept of interface complexity multiplier for compensating the …

System architecture analysis and selection under uncertainty
A system architecture analysis and selection methodology is presented that builds on the Multidisciplinary Analysis and Optimization framework. It addresses a need and opportunity to extend the MAO techniques to include a means to analyze not only within the technical domain, but also include the …

Hybrid power-system architecture for micro-grid
… conditions. This thesis looks at a hybrid power-system architecture that can boost fuel economy through coordinated variable-speed operation of both prime-movers and drive loads. The propulsion plant of an electric ship serves as an example of a micro-grid with a focus on efficiency and dynamic …

Genetic Control of Root System Architecture in Rice
… largely focused on aboveground phenotypes, root system traits represent potential unexplored targets for stress resilience and yield improvement. However, our understanding of the genetic control of root system architecture (RSA) in rice is fundamentally insufficient to contribute to these goals. …

System architecture for mode-matching a MEMS gyroscope
… The topic of this thesis surrounds a system architecture to optimize the performance of a gyroscope. The MEMS gyroscope contains a resonator and an accelerometer, modeled as a two degree-of-freedom mass-spring system. When the resonant frequencies of each mode are matched, the …

Separated spacecraft interferometry : system architecture design and optimization
Through a process of system design, analysis, and optimization, the trade space for future optical separated spacecraft interferometers (SSI's) is explored. Using Distributed Satellite System principles, eleven separate architectures ranging in size from three to five spacecraft are compared on the …

System architecture design of a robust heating system
… The objective of this thesis is to design a new system - at a high level - that would protect homeowners from the effects of power outages. To do this, interviews were conducted with people who have actually experienced power outages during winter. Their preference for continued space heating …
