I'am Dominik, an Austrian research and engineering enthusiast, and this is my research homepage. My current research interest considers intelligent energy applications in smart grids and smart metering. This includes the design and the analysis of intelligent techniques and algorithms to detect legacy, non-smart appliances in aggregated household power draws, the design of architectural and conceptual requirements for smart appliances and smart metering, the integration of smart and non-smart appliances into smart home, security aspects of smart metering as well as the ensuring of household and consumer privacy by intelligent concepts and algorithms.

Self-Organized Slot Synchronization on a Testbed By many prominent wireless communication techniques like e.g. S-Aloha synchronization techniques are becoming more and more important. In this master thesis we review a technique, which is able to synchronize a network of nodes in a self-organized way with only physical layer adaptation. The technique is called Meshed Emergent Firefly Synchronization (MEMFIS)and is a self-organized slot synchronization technique. This technique is based on Pulse Coupled Oscillators. We implement this synchronization technique on a hardware platform to test the synchronization performance. In more detail we review the synchronization speed and the synchronization precision under different conditions like parameter variations. Hence that, we compare the MEMFIS technique with the inhibitory/excitatory coupling technique, which is suitable for random delays and networks. Also for this technique we evaluate the synchronization performance. Finally, we compare both techniques to make a decision under which condition which technique is better. Master Thesis Download
CORDIC - Cordinate Rotation Digital Computer The CORDIC-algorithm (coordinate rotation digital computer) is a rotation-based iterative algorithm, with which it is possible to approximate trigonometrical functions like sine or cosine. In this paper, a fix-point FPGA implementation of the CORDIC-algorithm is represented. Further the pipeline implementation and the iterative implementation of the CORDIC-algorithm are compared. Lastly, an error-simulation of the different CORDIC modes with different coordinate systems is discussed. Bachelor Thesis Download
iBraitenberg - iPhone controlled Braitenberg Vehicle he Italien-Austrian cyberneticist Valentino Braitenberg introduced the concept of simple autonomous robots called Braitenberg vehicles. Such vehicles are built up of one or more electrical sensors controlling one or more actuators directly. In spite of the simple configuration the behavior of the vehicles with the environment can be very complex. The shown behavior can be even compared to human feelings like love, hate, fear or curiosity. The aim of this project is to implement the Braitenberg vehicles like Love, Hate, Fear and Curiosity on NXT Mindstorm robots from LEGO and to provide a control interface via an application for the Apple iPhone. With this app it is possible to control the vehicle and to visualize the used sensor and actuator intensity

One of my major research interests are related to evolutionary and metaheuristic algorithms. Therefore, I am studying different metaheuristic approaches as particle swarm optimization, simulated annealing, firefly optimization, cuckoo search optimization as well as differential evolution by applying these approaches to problem of load disaggregation. Load Disaggregation breaks down the household power draw to its appliance dependent components based on the power readings of smart meters. According to the problem of load disaggregation my recent research concentrates on unsupervised load disaggregation approaches. For that I am using Bayesian estimation and probabilistic graphical models. In detail, I am interessted in hidden Markov models and its modifications and how to infere the hidden state based on approximation methods such as particle fitlering. Moreover, I am interested in future applications of load disaggregation which go beyond the detection and identification of applainces in homes.
Title:['Smart Micro Grid Lab']
Type:['Project from 2012-2015']

Description:['The transformation from centralized to distributed energy resources brings new challenges for metering, pricing, communication, and distribution. We strive to optimize the combination of power networks and communication networks (so called smart microgrids) by self-organizing algorithms and mechanisms. An example is the intelligent integration of the behavior of all users (generators and consumers) of an electricity grid to optimize the operation of the system, e.g. by balancing energy consumption based on availability.This goal can only be achieved if an appropriate know-how is established and a large number of well-trained engineers that have experience in the area of smart electric grids become available. It is the objective of this project to contribute to the establishment of such know-how and to provide an experimental environment where motivated students can learn and gain practical experience in the domain of smart microgrids at Lakeside Labs.']

Description:['Nowadays, we are assisting to an increased interest in developing ICT solutions capable of improving the energy usage within houses. Increased energy efficiency and savings is a fundamental goal to contribute to the Sustainable Growth that is specified by the “Europe 2020″ strategy. A common though is that energy saving is achievable by letting the consumers be aware about the energy used by their household appliances, because most people have no idea on how electricity is generated or how it gets into their home. In this respect, a complete solution for monitoring and controlling the household appliances and devices is of great importance. Monergy will address these issues carrying out fundamental research about home-automation and developing concrete solutions for the increase of energy efficiency in the Friuli Venezia Giulia and Carinthia homes.']

Description:['Non-intrusive appliance load monitoring or load disaggregation is the problem of disaggregating running loads from overall consumption data. NILM is a single-meter approach with the objective to detect running appliances according to specific characteristics of their power signature. The increasing resolution of power measurements as a consequence of the rolling out of smart meters is going to provide a means for the detection of appliances. State-of-the-art NILM algorithms can be distinguished into supervised and unsupervised approaches where as I am mainly interested in unsupervised approaches. I am developing new algorithms and approaches for load disaggregation taken into account the complexity of the algorithms as well as of the problem itself.']
Description:['The increasing resolution of power measurements as a consequence of the rolling out of smart meters is going to introduce privacy threats. Tracking and monitoring of user behaviors and habits will be possible. Load disaggregation is going to provide disaggregated appliance information which either can improve energy awareness or introduce privacy issues. Therefore, I am interested to obfuscate the household power draw by smart algorithms and techniques. Therefore, I am using rechargeable batteries or controllabler, not user-driven applainces as the water boiler trying either to flatten the power profile as much as possible (battery case) or to produce artifical noise with the electric boiler (controllable appliance case)']
