An Integrated Tool For High Speed Circuits with Substrate Coupling.
… in this document. fREEDA implements local reference node instead of a global ground and this is crucial for distributed circuits. The models are implemented in object-oriented fashion and uses automatic differentiation. The same model can be used for DC, transient and harmonic balance …

Location Estimation in Wireless Communication Systems
… is highly sensitive to the positions of reference nodes. In this thesis, we also study on the reference node placement, and derive an optimum deployment scheme which can provide the best localization accuracy. Another challenge of wireless localization is due to insufficient number of …

Clock Synchronization for Multihop Wireless Sensor Networks
… by simple asynchronous broadcasts at each node. Changing the time reference node for synchronization is also easy, consisting simply of one node switching on adaptation, and another switching it off. It has been implemented on a Berkeley motes testbed of forty nodes, and comparative …

Semi-Analytical Model to Study Vibrations of High-Speed, Rotating Axisymmetric Bodies Coupled to Other Rotating/ Stationary Structures
… bodies. The model is developed in a stationary reference frame to avoid time-dependent coefficients in the equations of motion when coupled to stationary components. Surface constraints are developed using equivalent force relations between multiple points on the surface and a reference node. …

Improved Localization Algorithms in Indoor Wireless Environment
… localization error by placing refer- ence nodes in optimum locations, combining the localization information from accelerometer sensor in smartphone with Received Signal Strength (RSS) from reference nodes, and utilizing frequency diversity in Wireless Fidelity (WiFi) environment. …
