Consuming online communities : computer operating systems, identity and resistance
A defining feature of the modern era of computer technologies has been a massive 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 …

VORTOS : Versatile Object-oriented Real-Time Operating System
As computer software has become more complex in response to increasing demands and greater levels of abstraction, so have computer operating systems. In order to achieve the desired level of functionality, operating systems have become less flexible and overly complex. The additional complexity and …

Formalization Of Input And Output In Modern Operating Systems: The Hadley Model
… descriptive model of input and output for modern computer operating systems. Our model is intentionally inspired by the Open Systems Interconnection model of networking; I/O as a process is defined as a set of translations between a set of computer-sensible forms, or layers, of information. To …

Hierarchical supervisory control of complex Petri nets
Large, complex systems are prone to the phenomenon of livelocks. Once a system enters a livelocked-state, there is at least one activity of the modeled system that cannot be executed from all subsequent states of the system. This phenomenon is common to many operating systems where some process …

High Resolution Quantitative Auto-Radiography to determine microscopic distributions of B-10 in neutron capture therapy
… of programming environments and personal computer operating systems. Verification tests were conducted to ensure the continued accuracy of the underlying algorithms. Several experiments were conducted to demonstrate the applications of HRQAR. One focus of current BNCT research is the …

Hybrid Analysis Tools for Computer Systems Education
To learn about computer operating systems, students at Virginia Tech implement a command-line shell in their Computer Systems course. Successfully implementing the shell requires a deep understanding of operating system abstractions and interactions. Students often struggle with the project because …

General queueing networks with priorities. Maximum entropy analysis of general queueing network models with priority preemptive resume or head-of-line and non-priority based service disciplines.
… disciplines are widely used by existing computer operating systems. However, the mathematical analysis and modelling of these systems present great difficulties since priority schedulling is not compatible with exact product form solutions of queueing network models (QNM's). It is …

Improved Kernel Security Through Code Validation, Diversification, and Minimization
… running one of three commodity, general-purpose operating system families. In such operating systems the kernel software executes at the highest processor privilege level. If an adversary is able to hijack the kernel software then by extension he has full control of the system. This control …

Modeling of Airport Operations Using an Object-Oriented Approach
… study airfield ground traffic automated control systems with Just-In-Time forecasting and model system performance in a real-time ATC environment. The proposed generic library could be implemented into a Internet/intranet ready application which can query real time information and provide real …

On Intelligent Mitigation of Process Starvation In Multilevel Feedback Queue Scheduling
<p>CPU time-share process schedulers for computer operating systems have existed since Corbato published his paper on the Compatible Time Sharing System in 1962 [8]. With this new type of scheduler came the need to effectively divide CPU time between N processes, where N could be 2 or more …
