Isotonic regression by dynamic programming

Prof. Dr. Günter Rote | Freie Universität Berlin, Deutschland | Thursday, 19 September 2019 | 11:00 a.m. | N.2.01


For a given sequence of n numbers, we want to find a monotonically in- creasing sequence of the same length that best approximates it in the sense of minimizing the weighted sum of absolute values of the differences. A conceptually easy dynamic programming approach leads to an algorithm with running time O(n log n). While other algorithms with the same run- ning time are known, our algorithm is very simple. The only auxiliary data structure that it requires is a priority queue. The approach extends to other error measures.

When Controls meet Economics and Social Sciences

Dario Bauso | Friday 6 September | 11:00am | Lakeside Labs B04b B4 1.114

Abstract: The massive penetration of smart technology has changed energy systems and many other engineering applications such as transportation, logistics, and security. In all these contexts, one often observes a large number of machines and humans interacting with each other. Thus there is a need to redefine the boundaries of some engineering disciplines to accommodate both physical and socio-economic components. Control Engineering, the discipline which studies the ways in which one can control the evolution of a system is no exception. A core concept in control is ‘feedback’ whereby a machine (the controller) gets measurements from sensors about the state of the system one wishes to control and sets the inputs to the system. In the presence of numerous machines and humans, one observes the humans turning into strategic players who learn the environment and make decisions knowing that the environment (which is constituted by the other players) is at the same time learning about them and will react accordingly. This takes the concept of feedback to the next level and opens the floor to a number of game theoretic aspects (learning, incentives, pricing).

In this tutorial I will present new perspectives and challenges arising when dealing with co-existing physical and socio-economic components. I will introduce dynamic games with a large number of players, (also known as mean-field games) and discuss recent trends. I will also discuss the role of strategic thinking and learning in competitive scenarios. The tutorial will conclude with a look at bio-inspired collective decision making problems and related evolutionary game models.

Seminar on Cybersecurity and Control

12. September 2019 / 1 pm – 6 pm / z.1.09 / AAU

JOANNEUM RESEARCH ROBOTICS and the Department of Applied Informatics invite you to a series of four expert talks about security in the robotics domain, with a special focus on control aspects, vulnerability and security by design for future robots.

Speakers, Talks & Abstracts:

Nacim Ramdani (Université d’Orléans): Control Perspectives of Cyber Attacks

Abstract: Autonomous robots and most today’s critical infrastructures are cyber-physical systems (CPS) that operate in highly networked environments as they need to communicate remotely with control and management systems. This feature makes them more vulnerable to cyber-attacks. For instance, a scenario of importance is posed by a malicious adversary that can arbitrarily corrupt the measurements of a subset of (remote) sensors in the CPS. Because sensor measurements data are used to generate control commands, corrupted measurements data will lead to corrupted commands, thus critically affecting the behaviour of the CPS. 

From a control theory perspective, one needs to develop algorithms and architectures for the detection of cyber-attacks on either sensors or actuators, and the mitigation of their impact on the resilience and the overall performance of the CPS. State-of-the-art methods often consider active attack detection, control algorithms that work directly with encrypted sensor data, or secure state estimation methods that show resilience when sensors are under cyber-attacks.

In this talk, first, I will briefly review recent literature on cyber-security from the perspective of control theory. Then, I will describe our approach to secure state estimation, a secure interval state estimator for linear continuous-time systems with discrete-time measurements subject to both bounded-error noise and cyber-attacks. The interval state estimator is modelled as an impulsive system, where impulsive corrections are made periodically using measurement. The approach includes a new selection strategy that can endow the state estimation with resiliency to attacks, when assuming that only a subset of the whole set of sensors can be attacked although this subset is unknown a priori. The approach will be illustrated in simulation with robot navigation under cyber-attack.

Bernhard Dieber (JOANNEUM RESEARCH ROBOTICS): LiveDemo: Hacking the safety systems of a mobile robot

Abstract: Robots have integrated safety systems that are used to prevent incidents like collisions with bystanding humans. For mobile robots, this is mostly done with laser sensors. Since those systems are crucial components of a robot, they are engineered at a very high safety integrity level and use specialized, ultra-reliable, certified hardware components. Despite that, we have found a way to remotely disable the safety subsystem of a mobile robot thus turning it into a harmful device. In this live demonstration, we will show this hack and go into detail on the underlying vulnerabilities. We show supporting material and go into some details on current state and issues of robot cybersecurity.

Michael Hofbaur (JOANNEUM RESEARCH ROBOTICS): Active Diagnosis of Cyber Attacks using Physical System’s Redundancy

Abstract: Control systems define the physical interactions of robots or mechatronic systems in general. In that sense, they operate on the boundary between the physical and the cyber-physical world. Cyberattacks on a robot’s controller can thus cause physical danger to humans, systems and infrastructure. Security measures typically build upon advanced schemes for the underlying software components of robots or its underlying mechatronic devices. The talk, however, will explore schemes where the physical properties of a robot are deliberatively utilized to identify harmful cyber-attacks and thus draft possible corridors for novel cybersecurity measures for robot systems at the system’s level.

Stefan Rass (Technische Wissenschaften, Alpen-Adria-Universität Klagenfurt): Incentive-Based Robot Security – Game Theory for Safe and Secure Collaboration

Abstract: Developing robots in a team is a complex joint venture of achieving not only functional correctness, but also safety and security at the same time. While many mechanisms from system security (like cryptographic and others) are known and available, implementing these in a correct and effective way needs (i) a decent understanding of how the mechanism works, and (ii) considerable awareness that the mechanism is also needed. Time pressure and the complexity of the system’s function itself may be inhibitors that can cause security to receive secondary priority. When it comes to humans collaborating with robots or at least working in their proximity without protection, safety and security become primary concerns. This talk motivates an approach to system security that stems from game theory, and strives for incentives for people to care for security throughout the entire life cycle of a robotics system. The mere fact that a person can be harmed by a not-well-programmed robot may be insufficient, and better incentives are needed for security to become an effective part of future robotics. System security has lots of protections to offer, and game theory is anticipated as an aid for putting them to work. The talk will give an introduction to the ideas and possibilities that game theory has to offer to this end.

We are looking forward to welcome you at our event. Drinks and food will be provided!

Die Welt aus Schwingungen zusammensetzen!

Prof. Dr. Johannes Huber | 5. September 2019 | 16:00 Uhr | B04.1.06

Zum 250. Geburtstag von Joseph Fourier


Der französische Mathematiker und Physiker Joseph Fourier (1768 – 1830) erkannte, dass jede mathematische Funktion in einem begrenzten Definitionsbereich durch eine Summe von sinus-Schwingungen approximierbar ist, was nicht zuletzt für die Ingenieurwissenschaften von eminenter Bedeutung ist. Im Vortrag wird zunächst versucht, die Grundaussagen der Theorie allgemeinverständlich zu veranschaulichen. Anmerkungen zum Empfinden von Wohlklang und Dissonanz in der Musik anhand der Fourier-Reihenentwicklung von Schallwellen sowie hochaktuelle Erkenntnisse von Fourier zum Treibhauseffekt der Erdatmosphäre aus dem Jahr 1827 ergänzen den Vortrag.


Johannes Huber studierte Elektrotechnik an der Technischen Universität München und erwarb 1977 das Diplom. Er wurde 1982 zur Dr.-Ing. promoviert und erhielt 1991 den Titel Dr.-Ing. habil. mit einer Monographie zur Trelliscodierung. Von 1991 bis März 2017 war er Inhaber des Lehrstuhls für Informationsübertragung an der Friedrich-Alexander-Universität Erlangen-Nürnberg. Seit April 2017 ist er Prof. em. am Institute for Digital Communications (IDC) dieser Universität. Von 2007 bis 2009 war er Dekan der Technischen Fakultät.

In der Forschung ist Johannes Huber auf den Gebieten digitale Übertragung, Informations- und Codierungstheorie, codierte Modulation, Entzerrungs- und Detektionsverfahren, MIMO-Übertragungsverfahren, DSL etc. aktiv. Er hat zwei Monographien verfasst und ist Autor und Co-Autor von ca. 340 wissenschaftlichen Veröffentlichungen. In den Jahren 1988, 2000 und 2006 wurden Publikationen, die er verfasst bzw. mit verfasst hat, mit dem Preis der deutschen informationstechnischen Gesellschaft ausgezeichnet. 2004 erhielt er den Innovationspreis der Vodafone-Stiftung für Mobilfunk und in den Jahren 2003 und 2010 wurde ihm der EEEfCOM Innovationspreis verliehen.

Prof. Huber ist Fellow of the IEEE, Corresponding Fellow of the Royal Society of Edinburgh und ordentliches Mitglied der Bayerischen Akademie der Wissenschaften (BAdW). An der BAdW leitet er die Kommission „Forum Technologie“ und ist stellvertretender Sprecher der Sektion III: Naturwissenschaften, Mathematik, Technikwissenschaften

Inzwischen sind 11 seiner ehemaligen Doktoranden selbst Professoren an namhaften Universitäten und Hochschulen.

Review: On-the-fly Collaboration for Legacy Business Process Systems in An Open Service Environment [Slides]

The review of the TEWI colloquium of Prof. Liang ZHANG (Leon) Ph.D from July 5, 2019 comprises the slides (below):


Dynamic, distributed and open business forces enterprises to support various critical requirements, such as, timely reacting to changes, properly reusing business assets and smoothly collaborating with external partners. Existing approaches focus on mechanisms dealing with heterogeneity, but there is a lack of frameworks enabling legacy business processes performing collaboration in an open service environment. This paper proposes the L2L service framework featuring reactive IoT event messaging and coordinator-based collaborating between autonomous enterprises. Along with the emerging of coordinators, L2L empowers on-the-fly business process collaboration with dynamic changes. We present our experiments with a real-world scenario from the shipping industry of China.


Liang Zhang is a Professor of Computer Science at Fudan University, China. He received B.S. and Ph.D. degrees in computer science from Wuhan University, China. He has published over 70 journal and conference papers concerning multimedia databases, digital library, web services, and recently business process management (BPM). He is a Steering Committee Member of ICSOC, and has been the PC co-Chair of ICSOC 2013, General co-Chair of ICSOC 2012, publicity co-chair of BPM 2011, program co-chair of CBPM 2011, and NDBC 2011. His current research interests include XaaS infrastructure for CPS, and collaborative workflows for instant virtual organizations. He has been collaborating with Jianwen Su’s group at the University of California, Santa Barbara, Jian Yang’s group at Macquarie University, and Marlon Dumas at Tartu University. Recently, he collaborates with Prof. Hong-Linh Truong Aalto University, Finland, for IoT/BPM integration research. Dr. Zhang’s research has been supported by NSFC and other national agencies.
