System Performance Analysis for Multi-Band SweepSAR Operating Mode

Operating Mode Specific WCET Analysis

Many embedded control systems work in different operating modes, for example start-up, stand-by, shut-down and failure mode. These different operating modes usually have different timing requirements, and the different functional behaviour also leads to differences in timing behaviour. A Worst-Case Execution Time (WCET) analysis of such a system needs to determine mode-specific bounds on execut...

Performance and the Single/multi{processor Operating System Process Subsystem

Operating systems depend on process subsystem performance, which we analyze in Choices. We use compile time specialization to optimize both single and multiprocessor performance within a single design. We partition critical sections into two types, and compose independent control mechanisms to produce high performance, specialized locks. We select heavily used process operations and justify new...

Multi Agents for Heterogeneous Operating System Environments

As IT industries develop, upgrade and diversify, heterogeneous operating environments running a mix of new and legacy systems become increasingly important. Such environments are currently inadequate due to lack of compatibility with each other. This thesis investigates how agents can be utilised to facilitate such heterogeneous environments, aiding enterprise systems in building bridges betwee...

Dual-Band Evanescent-Mode Substrate Integrated Waveguide Band-pass Filter for WLAN Applications

A new multi-layer substrate integrated waveguide (SIW) structure is developed to design dual-band evanescent-mode band-pass filters (BPFs). Two independent series LC circuits are implemented by incorporating metallic irises in the different layers of the structure. The combination of the metallic irises with capacitive-plates is embedded inside the SIW to independently excite two evane...
