Characterizing the evolution of operating systems
… they evolve. This project is intended to analyze operating system trends and what are the factors that drive how they evolve. Basically, the following questions will be answered: "How to watch, predict, adapt to, and affect operating system's evolution trends?" In previous research, YF Chen used …

Protection in commodity monolithic operating systems
… real privilege separation within commodity operating systems by ""nesting"" a small memory management protection domain inside a monolithic kernel's single-address space: all the while allowing both domains to operate at the same hardware privilege level. This dissertation also demonstrates …

Multitasking operating systems for real-time applications
Multitasking systems are becoming increasingly used for implementing real-time systems since they are well-suited to asynchronous, often overlapping, events. With the availability of kernels such as Hunter and Ready's VRTX Operating System components, multitasking becomes a good alternative to …

User-Centric Power Management For Mobile Operating Systems
… that's because existing power management systems, which concentrate on controlling hardware power states, cannot effectively make these hardware components work in low-power mode. Why is this the case?</p> <p>Based on our analysis of 14 users' device usage trace, we found that background …

Consuming online communities : computer operating systems, identity and resistance
… reliance upon the mass consumption of personal operating system software. Currently three products dominate how the world experiences computer operating system – Microsoft‘s Windows, Apple‘s Mac, and Linux. The near monopoly held by Windows has been a crucial enabler of the ICT revolution, while …

Practical least privilege for cross-origin interactions on mobile operating systems
Mobile operating systems (i.e., mobile platforms) favor flexibility and re-usability as design principles and provide mobile applications with channels for establishing cross-origin interactions in an effort to realize these principles. Under this cross-origin scheme, applications accomplish tasks …
