TUCS Distinguished Lecture Series

TUCS Distinguished Lecture on 27.9.: Jan van Leeuwen

Friday, September 27, 2013 at 13.15

ICT Building, Auditorium Lambda

Coffee served from 12:45

Jan van Leeuwen, Dept of Information and Computing Sciences Utrecht University The Netherlands: "What is computation?"

Host: Ion Petre, Åbo Akademi University


Various new ideas have developed lately about computation. Do we actually know what it is, despite what Turing told us? Are ‘abstract state machines’ the answer? Do Valiant's ecorithms count as computation? We will survey a number of issues in the Philosophy of Computing and present a new, epistemological view of computation that may radically change our understanding of computational processes (joint research with J. Wiedermann). What are the challenges for computer science?

The TUCS Distinguished Lecture Series is a forum for public lectures by outstanding national and international researchers in all aspects of computing, coming both from academia and industry. All lectures are free and open to the public.

Åbo Akademi Department of IT coordinates national initiative on many-core computing

The "Parallel Acceleration" project is concerned with the efficient use of many-core processors. The goal is to develop methods for the development of efficient applications with low energy consumption.

Today it is not any more possible to increase the clock-frequencies of processors to achieve higher performance. This is due to energy- and heat-problems that arise at the high clock frequencies that would be needed. Instead processor manufactures have turned towards integrating more processor cores with lower clock-frequencies onto the die. It is however very challenging to build software that effectively exploits such many-core processors.  The project has been initiated by the Finnish IT-industry to find solutions to this big challenge.

The project "Parallel Acceleration" supports the Finnish IT-Industry in this central area, and aims to substantially improve the global competitiveness of the participating companies. Through the project opportunities for new innovative and competitive products are created

The total volume of the project is 3Meuro/year for 3 years. The project consortium consist of the main actors in the area: Nokia, Ericsson, Renesas Mobile, Nokia Siemens Networks, F-secure, ABB, CSC, Tampere University of Technology, Aalto University, University of Oulu and Åbo Akademi University.


The project is coordinated by Åbo Akademi, and Prof. Johan Lilius acts as the Principal Investigator and Responsible Leader of the project.

TUCS GP travel report: iV2013 by Annika Holmbom

Full name of the event: 17th International Conference on Information Visualisation (iV2013)

Place and date: London, U.K., July 15-18, 2013

Type of event: Conference

My article:

The scientific profile of the event: The scientific profile of the iV2013 conference was information visualization, including theory, practice, applications and evaluation. The main aim was to find new ways and ideas on how to visually present information better, so that it is more easily understandable to the user. The information that was visualized ranged from text from different sources, data, facial expressions and knowledge in different formats. Most of the participants had a background in other related topics, e.g. computer science and information systems, with information visualization as an important part of their research.

Opinion on the best paper and its topic: The presentation I had been waiting for was a keynote given by Eugene Sorenson from Bloomberg, NY, USA “Visual Analysis of Financial Data”, but an unexpected power cut took place in the middle of his presentation. He gave the presentation the following day, but it was simultaneously with my own presentation, so unfortunately I missed it.

One session was in my opinion really interesting, though a bit different and artistic: Vis2013_1.8: Visualization, Art, and Design. The chair of the session was Prof. Vladimir Geroimenko from Plymouth University, UK. The three presentations given were:

  1. “Virtues and Vices: Examples of Medieval Knowledge Visualization” by Francis T. Marchese, Pace University, USA.
  2. “A mathematical look to the world” by Hervé Lehning, www.lehning.eu, France, and
  3. “Magic Squares and Aesthetic Events” by Hans Eberhard Dehlinger, Fang You, Jian Ming Wang and Ming Jiao, from University of Kassel, School of Arts, Germany; School of Communication and Design, and School of Software, Sun Yat-sen University, Guangzhou, China. Note: This last presentation gave me a clue on how Marimekko creates their fabulous designs on their fabrics. Not the ones lately accused of plagiarism, but the more “mathematical” ones consisting of stripes and boxes.

Number of participants: approx. 80-100 participants

Social events: Visualisation Social Networking Event was an evening cruise on the river Thames. A buffet dinner was served on the boat.

Touristic impressions: The conference venue was located in the central part of London within a walking distance from several interesting locations and with good tube and bus connections all over London city.

TUCS GP travel report: Research Visit to University of Southampton by Inna Pereverzeva

Full name of the event: Research visit to University of Southampton, UK, group of Michael Butler

Place and date: Southampton, U.K., May 1st - July 1st, 2013

Type of event: Research visit

The scientific profile: Michael Butler is internationally recognised as leading in refinement-based formal methods. He has made key methodological contributions to the Event-B formal method, especially around model composition and decomposition. He plays a leading role in the development of several tools for B and Event-B especially the Rodin toolset.

The aim of my research visit was to work on the principles of architectural decomposition. This topic is very important for achieving the objectives of my thesis.

Currently I have thoroughly studied the principles of specifying and verifying fault tolerant systems. The next important step towards defining a formal development technique for autonomic distributed systems is to integrate architectural decomposition into the development process. In our group, we do not have an experience in event-based decomposition, which is the main technique for deriving a distributed architecture.

During my visit I mastered the principles of atomicity decomposition and model decomposition in Event-B. Atomicity decomposition is one of the techniques to help with the structuring of refinement-based development of complex systems in Event-B. Atomicity decomposition diagrams provide a systematic means of introducing control structure into the Event-B development process. It provides a means to express refinement relations between events of different refinement levels, through a set of hierarchal diagrams. In addition it can be merged with model decomposition technique to manage the complexity of large models.

Based upon the research results during my visit, currently we are writing a paper entitled "Formal Derivation of Fault Tolerant MapReduce", co-authored by Inna Pereverzeva, Michael Butler, Asieh Salehi Fathabadi, Elena Troubitsyna and Linas Laibinis.

Full name of the event: XXXIII Sunbelt Social Networks Conference of the International Network for Social Network Analysis (INSNA)

Place and date: Hamburg, Germany, May 21-26, 2013

Type of event: conference

My article:

The scientific profile of the event: It is a multi-disciplinary conference covering all kinds of topics using SNA (Social Network Analysis).

Opinion on the best paper and its topic: There have been almost 700 paper presentations in the conference, so it is not possible for me to attend all of them. I can only tell that the sessions focusing on mixed method are most interesting for me. For example, Alan Sloane’s presentation titled “Socio-economic Process and Network Structure- Integrating Network and Qualitative Analysis” is very inspiring for my own research.

Number of participants: 1000+

Social events:

Touristic impressions: Hamburg is a big city, with many good restaurants. However, the weather was too rainy for the conference name of “Sunbelt”.

TUCS GP travel report: iV2013 by Samuel Rönnqvist

Full name of the event: 17th International Conference on Information Visualisation (iV2013)

Place and date: London, U.K., July 15-18, 2013

Type of event: Conference

My article:

The scientific profile of the event: The conference is a long-running conference on Information Visualisation, organized annually by the Information Visualisation forum. It has a wide focus ranging from information visualization theory to application. The participants mostly have their stronghold in computer science and visualization, but many come from widely varying areas including business, arts and engineering.

Opinion on the best paper and its topic: The best paper/presentation was perhaps ”Defining Visual User Interface Design Recommendations for Highway Traffic Management Centres” by Johanna Haider et al., which reviews literature from the human-computer interaction, cognitive psychology and information visualisation fields to the end of presenting a concise set of guidelines for the design of visualisations. The focus stems from requirements in systems for monitoring traffic flows, but is highly applicable to visualisation of any spatio-temporal data. The article constitutes a good entry point for anyone interested in the design of visualisation interfaces.

Number of participants: approximately 80

Social events: Conference dinner on river cruise

Touristic impressions: The conference venue was situated on the University of London campus in central London, with many sights conveniently nearby. Of special topical interest, I can mention the currently running Alan Turing exhibition at the Science Museum, as well as Broadwick Street (with its historical John Snow pub) in Soho.

TUCS GP travel report: Advanced RF Implementation Flow by Rajeev Kanth

Full name of the event: Advanced RF Implementation Flow

Place and date: Oxford, UK, January 14-18, 2013

Type of event: Summer School

The scientific profile of the event: This summer school was a five days intensive course which includes theoretical lectures and hands on lab exercises on implementation of widespread IC design skills in advanced deep submicron technologies and microwave passive component design and simulation. I have gained five credits for my doctoral studies. This course is very useful for me as my future research work may align towards this course theme.

Opinion on the best paper and its topic: In my opinion, the best lecture delivered was by A. Koukab, Professor of EPFL. The name of the topic was mixed mode SoC design and simulation technology.

Number of participants: 30

Social events: As the course was intensive, the social event did not take place.

Touristic impressions: Oxford and London are the famous touristic attractions nearby. I enjoyed the summer school.

TUCS GP travel report: ICSE-13 and MTD-13 by Johannes Holvitie

Full name of the event: 4th International Workshop on Managing Technical Debt (MTD) and 35th International Conference on Software Engineering (ICSE)

Place and date: San Francisco, USA, May 18-26, 2013

Type of event: Workshop and Conference

My article:

The scientific profile of the event: ICSE is regarded as one of the most influential conferences for the fields of software engineering and development. This was evident for this year's conference as well and could be measured in the number of high profile academia and industrial attendees. The MTD workshop was co-held within the ICSE conference. While this event is one of its kind when it comes to the field of software technical debt management and its research, the number of attendees taking part in this workshop indicated that the field was in very much an upward trend.

Opinion on the best paper and its topic: I was most intrigued by "Exploring Software Supply Chains From a Technical Debt Perspective", a paper by Monteith and McGregor. In this paper they discussed the use of betweenness centrality metric to indicate areas of a software implementation that were likely to be changed in the event of technical debt governance. The showcased experiment indicated that this metric was indeed very close to identifying those areas that were actually changed by expert developers. I found the paper to be of high quality and the presented approach to be something that I must get more acquainted with later on in my own research.

Number of participants: for ICSE circa 1400 and for MTD close to a hundred

Social events: As part of the ICSE, there were sponsored lunches as well as a banquet cruise with dinner. Excepting the cruise, this applied for MTD as well. Additionally, a tour around Silicon Valley including visits to and presentations from major companies.

Touristic impressions: San Francisco is a place of numerous sights. From this plethora, the most notable ones that I had a chance to visit were the Golden Gate Bridge, Pier 39, Lombardo Street, the Coit Tower, and the Cable Cars.

TUCS GP travel report: PAAMS 2013 by Natalia Díaz Rodríguez

Full name of the event: 10th International Symposium on Distributed Computing and Artificial Intelligence within PAAMS (11th International Conference on Practical Applications of Agents and Multi-Agent Systems)

Place and date: Salamanca, Spain, May 22-24, 2013

Type of event: Symposium

My article:

The scientific profile of the event: Most of the papers and topics were around agents. However, very diverse papers were presented on distributed computing and on Ambient Intelligence, since there was collocated 6 different events at the same time (http://dcai.usal.es/events)

Opinion on the best paper and its topic: I found very relevant for my research two papers, the first one entitled Multimodal Indoor Tracking of a Single Elder in an AAL Environment by Ismail and Florea, and the second, entitled Kitchen AS-A-PAL: Exploring Smart Objects as Containers, Surfaces and Actuators by Surie et al.

Number of participants: about 200-300

Social events: There was a cocktail reception at Palacio Anaya, a very nice old palace with patios and typical Spanish tapas. There are plenty of patios in Salamanca in all the historical buildings, which are very well conserved and still today serve as main faculty buildings. There was also a guided tour around the old city, a gala dinner and two nights socializing at a bar/pub.

Touristic impressions: Uni. Of Salamanca is the oldest universities in Spain and the third oldest in Europe. I could say it is one of the most beautiful cities in Spain, it is full of students and it is small; everything in the city is within walking distance.
