Enabling Location-based Services using Wearable and Handheld

Smartphones, or more general handhelds, which are commonly used for indoor localization purposes, are not a viable option in places where people do not carry them all the time, e.g., home and office. Alternatively using wearable devices brings along limitations in regards to power supply, processing capability and availability of sensors, which...

Towards Real-Time Power Restoration Using a Hybrid Genetic Algorithm

The goal of this project is to use a hybrid genetic algorithm to restore power to a power grid after a blackout by minimising the lost load and number of switches within a reasonable amount of time for power operators. The algorithm was tested on single-fault and multi-fault blackout systems. Based on the simulation results, the performance of...

A Compact, High Precision Position Sensing Embedded System for Fast Steering Mirror

A fast steering tip-tilt mirror is widely used as a pointing and tracking device in aerospace engineering, in laser beam stabilizers and in many other applications. A fast steering mirror has the capability to project light in two-dimensional space. The correct positioning of the mirror is crucial for the device overall operation. In this...

Network Lifetime Analysis of Data Collection Protocols

When a sensor network is deployed, we fundamentally care about three main outcomes: to obtain as much data as possible (high delivery rate), to obtain data as fast as possible (low latency), and to obtain data for as long as possible (long lifetime). This last metric, called network lifetime, is of great importance and has been widely...

Power efficient digital correlator in the scope of an UWB baseband design

Ultra Wideband (UWB) radio represents a promising way of communication for low power applications in interference-prone environments. For achieving a low power solution the digital baseband architecture needs to be carefully optimized to reduce the total power consumption. Particularly for the computationally intensive synchronization phase that...
