Priority inheritance protocols: an approach to real-time synchronization
TL;DR: An investigation is conducted of two protocols belonging to the priority inheritance protocols class; the two are called the basic priority inheritance protocol and the priority ceiling protocol, both of which solve the uncontrolled priority inversion problem.
Proceedings ArticleDOI
Cyber-physical systems: the next computing revolution
TL;DR: The design, construction and verification of cyber-physical systems pose a multitude of technical challenges that must be addressed by a cross-disciplinary community of researchers and educators.

TL;DR: Boss is an autonomous vehicle that uses on-board sensors to track other vehicles, detect static obstacles, and localize itself relative to a road model using a spiral system development process with a heavy emphasis on regular, regressive system testing.
Proceedings ArticleDOI
A resource allocation model for QoS management
TL;DR: This work presents an analytical model for QoS management in systems which must satisfy application needs along multiple dimensions such as timeliness, reliable delivery schemes, cryptographic security and data quality, and refers to this model as Q-RAM (QoS-based Resource Allocation Model).
