A Real-Time System for Color Sorting Edge-Glued Panel Parts
… thesis describes the development of a software system for color sorting hardwood edge-glued panel parts. Conceptually, this system can be broken down into three separate processing steps. The first step is to segment color images of each of the two part faces into background and part. The second …

Real-time System Scheduling and Information Theory: From Uniprocessors to Multiprocessors
… background to represent the uncertainty of a system. For real-time systems, task scheduling is one of the most studied topics due to the constraint that all the tasks in the system have of meeting their deadlines. In this work, we present the foundation for using these definitions from …

Scheduling in Real-Time Systems to Ensure Graceful Degradation: The Imprecise-Computation and the Deferred-Deadline Approaches
When a real-time system becomes overloaded, we want the system to degrade in a graceful, predictable manner. Imprecise computations and deferred deadlines are two approaches to provide this graceful, predictable degradation.

Utilizing slack time for aperiodic and sporadic requests scheduling in real-time systems
A real-time system typically has a mixture of periodic and aperiodic workload. Requests in each periodic task have regular arrival times and hard deadlines. Aperiodic requests, on the other hand, have random arrival times and may have hard or soft deadlines. We called these aperiodic requests with …

Applications and extensions of the imprecise-computation model
Real-time systems have become increasingly important in a growing number of application domains such as telecommunication networks and multimedia. The tasks in such a real-time system must produce logically correct results by their deadlines. The correctness of such a system depends not only on the …

Two concrete problems in timing analysis of embedded software
… timing analysis is crucial for the design of real-time embedded systems. Static analysis methods analyze a program statically to give an upper bound on the worst case execution time (WCET) of the program. The problem of determining WCET of a program by static analysis methods has to be solved …

Fault-Tolerant Scheduling and Broadcast Problems
Incorporating fault-tolerance into a computer system involves redundancy and therefore increases the system's cost. An investigation into this cost is initiated by considering the application of fault-tolerance to two standard problems: scheduling responses to periodic requests in a real-time …

Probabilistic Analysis and Scheduling of Critical Soft Real -Time Systems
Allowing a real-time system to miss some deadlines in exchange for better average performance increases the possibility of overload. While overload in real-time systems has been studied, the emphasis has been on hard real-time systems in which overload is an exception whose occurrence is to be …

Planitia : a real-time fuzzy-logic tilt controller
Cybernetics and Systems Science are inter-disciplinary sciences that tend to focus on the complex systems such as organisms, ecologies, minds, societies, and machines. Cybernetic systems are regarded as complex structures which are built over underlying laws and principles that can be used to unify …
