System Identification Of A Pasteurisation Process: A Comparison Of Direct And Indirect Methods, Niel Canty
System Identification Of A Pasteurisation Process: A Comparison Of Direct And Indirect Methods, Niel Canty
Theses
The primary focus of this research is to identify a linear model for a direct steam injection (DSI) pasteurisation process which is a component of a large-scale pilot evaporation process widely used in the dairy industry. The pasteurisation process has been identified as a key component of the evaporation process. The author believes that no previously published work has focused on identifying models for a DSI pasteurisation process which makes this work an original contribution to the area. The pasteurisation process can be modelled as a single-input, single-output (SISO) process with a measurable disturbance. Thus two transfer functions were required …

Remote monitoring is used in many applications within the scientific, industrial and commercial communities. These applications can range from the simple monitoring of wind farm generators to the complex behavioural monitoring of a local fox habitat to the simple but extremely urgent monitoring of water depth for a flood prone river. Each application of remote monitoring requires different aspects of the remote monitoring device, but typically, not all these applications can be implemented, as the technologies required for their construction are extremely large, expensive, energy inefficient, slow and do not meet the constraints for the given application.
However with the …
Disappearing User Interface In Ubiquitous Computing: A Pointing And Gesture Sensing System Using An Ultrasonic And Radio Frequency Location Technology, Stephania Yimana Kigadye
Disappearing User Interface In Ubiquitous Computing: A Pointing And Gesture Sensing System Using An Ultrasonic And Radio Frequency Location Technology, Stephania Yimana Kigadye
Theses
Weiser’s [1] vision of ubiquitous computing presents a different paradigm of computing which attempts to push computers into the background towards invisibility. Therefore “new concepts for human-computer interaction have to be developed when envisioning ubiquitous computing scenarios [1]. Instead of a single screen-based user interface (UI), humans will interact with a number of devices that are distributed and interconnected. These eomputers range from highly personal and mobile applianees to systems that are integrated in everyday environments and are more or less invisible.”[7] As this project suggests, a disappearing user interface in ubiquitous computing can be designed as a gesture recognition …
Ultra Wide Band Radar For People Location And Tracking, Julien Le Kernec
Ultra Wide Band Radar For People Location And Tracking, Julien Le Kernec
Theses
The development of the UWB radar for people location and tracking was motivated by the need for a location and tracking system that performs well indoor. The objectives of the project are:
1. Conduct literature surveys of Ultra Wide Band and Location & Tracking.
2. Determine which UWB pulse is the most suitable for the UWB radar.
3. Design the concept of the UWB radar based on the literature reviews and the UWB pulse chosen.
4. Build an UWB radar prototype.
5. Measurement and Evaluation of the prototype.
This thesis introduces UWB key historical developments and properties; but also, its …
Linux Based Pda Gateway For Wireless Sensor Networks, Áine Mccarthy
Linux Based Pda Gateway For Wireless Sensor Networks, Áine Mccarthy
Theses
Recent years have seen a dramatic increase in the development and deployment of intelligent sensors and their use with a plethora of networking protocol technologies. Wireless Sensor Networks (WSN) can be used to monitor the environment, objects in the environment and the interaction of these objects with each other. Examples include environment and habitat monitoring, structural monitoring, disaster management and emergency response. The deployment of such large-scale WSN possess many challenges, the most important being scalability, portability, fault tolerance, adaptability and ubiquitous connectivity. There also exist many challenges when trying to establish communication with WSN. WSN can function as a …
Efficient Strategies For Robust Constrained Model Predictive Control, Marcin Tomasz Cychowski
Efficient Strategies For Robust Constrained Model Predictive Control, Marcin Tomasz Cychowski
Theses
Practical difficulties associated with the implementation of stabilizing robust model predictive control (MPC) laws are well known. The algorithms typically rely on the solution of the so-called min-max optimization problem. All such algorithms display a large online computational burden and often suffer excessive conservativeness. In this thesis, two original algorithms will be developed that address the conservativeness and complexity issues in min-max MPC.
The first algorithm is a min-max MPC based on the concept of closed-loop prediction. The synthesis procedure is realized using linear matrix inequalities and thus the implementation of the closed-loop min-max MPC control law can be performed …
