Joint Master Thesis with SenseFly (Lausanne)

Mittwoch, 28. Mai 2014 13:19

As part of our SINUS research project (http://uav.aau.at), NES is offering a joint master thesis with SenseFly (http://www.sensefly.com) – a leading drone company located in Lausanne, Switzerland. Interested students are requested to contact Prof. Bernhard Rinner.

Project Description

senseFly Ltd, a spinoff of the Swiss Federal Institute of Technology (EPFL) in Lausanne, develops and commercialises mini-drones for civilian applications in the domain of 2D and 3D mapping. The maps generated with these drones are used for such applications as construction, mining logistics, forestry, conservation, crop monitoring or humanitarian aid. As part of its extensive research and development program, senseFly is looking for motivated engineers and programmers to develop, design, test and even release to market new hardware and software modules for our mini-drones. As an intern or master’s student, you will be integrated directly with our dynamic team of engineers and researchers working on new products on the cutting edge of aerial robotics. Projects have a duration of 6 months and can be tailored based on the competencies of the applicant.

The proposed thesis project involves the development of smart flight planning algorithms for swarms of fixed-wing eBee drones (https://www.sensefly.com/drones/ebee.html). Current planning algorithms split an area of interest into one or several flight plans based on an estimate of the time required to complete the flight. The goal of this project is to expand this algorithm to include dynamic re-planning during flight based on several factors, including remaining battery level, area covered, wind estimation, the number of drones in the air, etc. Algorithms will first be prototyped using a simulator and then tested in the air using several drones. If successful, the algorithms will be integrated into a future release of our flight planning software.

Interested students should have knowledge in programming (C++, experience with Qt a plus), mathematical modelling and communication protocols. Experience with drones is a plus. Please send your application including a current CV and your student records (Studienerfolgsnachweis) to bernhard.rinner@aau.at.

Open Master’s Thesis: Voice-based interaction with an Unmanned Aerial Vehicle (UAV)

Montag, 12. Mai 2014 13:51

The Interactive Systems Research Group offers a Master Thesis on developing a voice-based user interface to control a flight of a UAV.

Navigating a UAV is not an easy task that requires initial instructions and an extensive training to become proficient.  One of the ways to reduce the time for preliminary preparation and, in general, to simplify an operator’s work is to develop a more natural and intuitive user interface.

In the last decades, many scientific efforts have been made with an ultimate goal to develop a Natural User Interface (NUI). The word “natural” implies that the target interface would provide an easy and fast way to interact with a system. As speech is among the most natural ways of communication, it is proposed to develop a user interface with speech as a core modality.

Diplomarbeitsthema: Implementierung eines Interval OLAP Ansatzes

Montag, 24. Februar 2014 12:05

On-Line Analytical Processing (OLAP) ist eine Methode um Daten entlang unterschiedlichster Dimensionen zu analysieren. Eine typische OLAP Anfrage könnte zum Beispiel sein: „Wie hoch war der Absatz der Produktgruppe A in der Region B im Zeitraum T“, in der Absatzdaten entlang der drei Dimensionen Produkte, Region und Zeit analysiert werden. Die Daten zur Beantwortung solcher Anfragen stammen meist aus einem Data Warehouse. Beide Bereiche, OLAP und Data Warehousing, sind bereits seit Jahrzehnten in praktisch jedem größerem Unternehmen im Einsatz.

In der Forschung ist in den letzten Jahren unter anderem das Thema „Sequential OLAP“ stark vorangetrieben worden. Dabei werden Methoden und Verfahren erforscht, um Sequenzen in Data Warehousing Systemen zu analysieren. Eine solche Sequenz könnten zum Beispiel Patientendaten einese Hospitals sein: eine Patientin wird auf einer Abteilung A aufgenommen -> es folgt eine erste Diagnose -> die Patientin wird verlegt auf eine Abteilung B -> es folgen mehrere Untsuchungen und Behandlungen -> die Patientin wird entlassen. Für traditionelle OLAP Ansätze ist das einfach eine Menge von unabhängigen Daten. Sequential OLAP betrachtet einen solchen Datenstrom jedoch als eine Sequenz von Daten, was zusätzliche Abfragemöglichkeiten erlaubt.

Eine Erweiterung dieses Ansatzes, welcher an der Universität Klagenfurt entworfen wurde, ist die Analyse von Intervaldaten in einem „Interval OLAP“ System. Dabei spielt nicht nur eine Sequenz von Daten eine wichtige Rolle, sondern auch die sich daraus ergebenden Intervalle. Als einfaches Beispiel können hier die Daten eines „Intelligenten Gebäudes“ dienen. In einem solchen Gebäude werden unterschiedlichste Daten gesammelt: wann wird das Licht in einem Büro ein- bzw. ausgeschalten? Wann läuft die Heizung? Zur Beantwortung einer Frage wie „Wie lange ist in den Büros des Gebäudes A im Zeitraum A durchschnittlich das Licht an?“ braucht es zusätzliches Wissen über die Intervalle zwischen den einzelnen Ereignissen (Licht An, Licht Aus).

Die zu erstellende Diplomarbeit soll sich mit dem Entwurf und der Implementierung einer Abfragesprache für einen solchen Interval OLAP Ansatz beschäftigen. Dabei kann auf eine bereits existierende Abfragesprache (und deren Implementierung in PHP, PostgreSQL) im Bereich Sequential OLAP zurückgegriffen werden.

Open Master-Thesis: Partitioning of Inter-Organizational Processes with Data-Flow.

Montag, 27. Januar 2014 12:01

Inter-Organizational processes are a vital feature for today’s businesses. For example an online shop is actually realized by different partners: The online shop itself, a logistics company ships the goods and a bank is responsible for the credit card transactions. Today inter-organizational processes are typically implemented according to more or less abstract process models. This results in tedious and error-prone manual work.

In general there are two approaches for inter-organizational processes: On the one hand orchestrations, that are based on a central coordinator and on the other hand choreographies that support a fully distributed operation. The choreography approach has the advantage that the autonomy of the differ-ent partners is preserved.

We have already developed a partitioning approach for the top-down generation of choreographies. In this approach first a global process is defined. In a next step each element of the global process is as-signed to one of the partners. Finally our algorithms automatically generate private processes/views for each partner. These private processes can either directly be executed or they can be extended by the partners.

The existing version of the partitioning procedure concentrates on the control-flow and abstracts from the data-flow. In our current research not only the control-flow but also the (potentially complex) data-flow is subject to partitioning. This is an important topic because it allows to preserve the privacy of the partners and customers. The principle idea is that a partner must only get access to some variable which is defined in the global process if he/she really needs it.

We provide the unique opportunity for one master student to participate in research on this highly relevant topic in the field of inter-organizational processes. The student working on this thesis will actively participate in our research team. In particular he/she will focus on the implementation and evaluation of the approach.  The implementation will be based on existing software and frameworks of our research group.

Open scholarships for Master thesis

Mittwoch, 18. Dezember 2013 20:25

drone

New scholarship opportunities for Master thesis in an interdisciplinary project on the use of UAV networks for delivery of goods.

Delivering goods via a network of small unmanned aerial vehicles (UAVs) becomes an option if classical means of transportation like trucks, trains, and planes fail. On the one hand, this comes about if roads, railway tracks, or landing facilities do not exist, if natural disasters make it impossible to use them, or if classical means of transportation are too dangerous in crisis areas. A compelling task for a ‘delivery-by-UAV service’ is, for example, the provision of medical products tailored to the instantaneous needs of patients in Africa’s remote areas, and the comprehensive supply of nutrition and (purified) water in case of emergency. On the other hand, the establishment of an air-borne supply service in densely populated metropolitan areas is also worthwhile, since congestion often makes roads nearly impassable.

 

Master thesis 1: „How much should be charged for delivering commercial goods by a network of UAVs?”
(Informatics / Business Administration / Mathematics / Information Technology)

We are looking for an individual eager to rise to the challenge of analyzing how such a delivery-by-drone service should be priced, and in which way the pricing strategy should respond to the current level of consumer satisfaction. Since all results should be obtained by utilizing an agent-based system, some understanding of object-oriented programming would be appreciated (e.g., Python); some knowledge of the principles of economics would be more than welcome.

A scholarship of 300 € per month will be available to the successful applicant.

 

Master thesis 2: „Performance evaluation of a network of UAVs delivering commercial goods”
(Informatics / Business Administration / Mathematics / Information Technology)

One critical issue in networks of UAVs is the coordination of the flying robots. The aim of this work is to evaluate the impact of on-line coordination algorithms on system performance. The evaluation will be performed by using agent-based simulations. To this end, some understanding of object-oriented programming would be appreciated (e.g., Python).

A scholarship of 300 € per month will be available to the successful applicant.

Bachelor Topic: Android app „Energy Meter“

Freitag, 20. September 2013 11:10

CounterCurrent meters show the consumed energy as a 7 digit number displayed on the front of the meter casing. The goal is to develop an Android App that periodically makes a photo of the meter and extracts the value via OCR. The work can built upon existing routines for OCR, but needs to be tailored to handle possibly out of focus images and to take knowledge from previous measurements into account.

This topic can also be done as a research project or a masters thesis. For a masters thesis topic, the work should also include a measurement campaign and an interpretation of the data. Applicants should have basic experiences with Android programming and be in the „Information Technology“ or „Informatik“ study program.
The topic is offered at the group of Prof. Wilfried Elmenreich at the Insitute of Networked and Embedded Systems.

Further topics (Bachelor/Master thesis/Research Projects) for can be found at the Smart Grid Blog and the Self-Organizing Networked Systems Blog.

Softwarepraktikum WS 13/14: Side-Channel Angriffe

Montag, 16. September 2013 9:41

Chipkarten dienen üblicherweise der Speicherung und sicheren Verwaltung von geheimen Informationen, wie etwa kryptographischen Schlüsseln. Im Fall der Bürgerkarte etwa, speichert die Chipkarte einen geheimen Signaturschlüssel und berechnet eine digitale Signatur für ein extern zugeführtes Dokument. Obgleich hierbei keine Information über den geheimen Schlüssel auf direktem Weg die Chipkarte verlassen, können Messungen des Magnetfeldes um den Chip, sowie Messungen der Stromaufnahme der Karte Rückschlüsse auf die internen Abläufe (Berechnungen) innerhalb des Chips, und somit auf geheime Informationen liefern, welche gerade verarbeitet werden. Im schlechtesten Fall lässt dies direkte Rückschlüsse auf private kryptographische Schlüssel zu.

Solche als Seitenkanal-Angriffe bekannten Attacken stellen aktuell eine der größten Bedrohungen für die Sicherheit von Chipkarten bzw. kryptographischer Hardware im Allgemeinen dar.

Um Seitenkanalangriffe zu verstehen und auch verhindern zu können, müssen kryptographische Protokolle implementiert, und Seitenkanal-Informationsflüsse explizit simuliert werden. Ziel der Arbeit (Wahlfachprojekt / Diplom- / Master- / Bakk-Arbeit) ist die Konzeption und Schaffung einer Testumgebung, in welcher ein kryptographisches Verfahren implementiert, und Seitenkanal-Abhörangriffe einfach simuliert werden können. Die Ziele der Arbeit sind im Einzelnen:

  • Aufarbeitung der Konzepte und Ideen von Seitenkanalangriffen
  • Konzeption einer Testumgebung, in welcher Seitenkanalangriffe simuliert werden können
  • Test und Bewertung von bekannten Gegenmaßnahmen gegen Seitenkanalangriffe, mit Hilfe der implementierten Testumgebung („spielen Sie den Angreifer, und versuchen Sie ein Krypto-Verfahren durch einen Seitenkanal zu knacken“).

Der Kreativität sind keine Grenzen gesetzt. Der/m Studierenden steht es nach Absprache mit dem Betreuer frei, die verwendete Programmiersprache frei zu wählen. Das Projekt kann als Wahlfachprojekt auch im Team abgewickelt werden. Tiefgehende Kenntnisse der Kryptographie sind nicht erforderlich. Benötigt wird jedoch ein gutes Verständnis von Rechnerorganisation, sowie Boole’scher Schaltungen.

Projektverlauf und Aufgaben:

  • Einarbeitung in die Ideen und Konzepte von Side-Channel Angriffen
  • Konzeption der Simulationsumgebung
  • Implementierung, Beschreibung und (Performance-) Test

Rahmenbedingungen:

  • Projektstart:  Ab sofort!
  • Projektende: 6-8 Monate nach Beginn (excl. Einarbeitungszeit)

Voraussetzungen:

  • Ausgezeichnete Kenntnisse der Programmiersprache Java
  • Grund-Kenntnisse der Kryptographie
  • Gute Kenntnisse im Bereich der Rechnerorganisation
  •  (programmiertechnische) Kreativität
