Review: New Media Services from a Mobile Chipset Vendor and Standardization Perspective [Slides]

The review of the TEWI colloquium of Dr. Thomas Stockhammer from November 30, 2018 comprises the slides (below):

Abstract: The media landscape changes significantly over the last few years by new content formats, new service offerings, additional consumption devices and new monetization models. Think of Netflix, DAZN, Mediatheks, mobile devices, interactive content, smart TVs, Virtual and Augmented Reality, and so on. Many of these efforts have been realized by a limited usage of standards, but are standards irrelevant? Secondly, more and more services are enabled by latest mobile compute platforms enabling new services and experiences. This presentation will provide an overview some of these trends and will motivate the development of global interop standards. Specific aspects will include the move of linear TV services to the Internet (both mobile and fixed) as well recent advances on Extended Reality and immersive media trends.

Interactive Objects for Graph Algorithmic Thinking

Andrea Bonani | December 10, 2018 | 11:00 | B01.0.14

Abstract:
In parallel with the rapid growth of digital technology and its pervasiveness in everyday life, it emerged the need to introduce knowledge of computer science at school, from the early years of the scholastic curriculum. This is not intended to promote programming careers among students, nor because they shall work in areas related to Information Technology, but because already in the present times, and more in the future, aware citizens must have digital skills and competences in order to be fully integrated into our society.
In the last decade Computational Thinking has gained attention as a way for schools to develop those skills required by the current digital age. Algorithmic thinking is at the core of Computational Thinking and tangible interactive solutions can help children develop algorithmic thinking skills.
This talk focusses on exploratory research concerning tangibles for graphs and graph algorithmic thinking (GAT) for learners aged from 9 to 15 years. The purpose of this research is to promote Algorithmic Thinking at school, by means of multi-sensory physical activities and learning-by-doing. Specifically, the research uses inter-connected interactive tangible objects. Manipulating tangibles fosters interplay between abstraction and concreteness, so as to enable learners to learn through visual and tactile experiences.
By following an action research process, interactive objects for GAT evolved through prototyping and actions-studies. The talk overviews their evolution and delves into its most recent action: an ecological study with learners using tangibles for GAT. It ends by reflecting on results and future work.

CV:
Andrea Bonani is a PhD student at the Faculty of Computer Science, Free University of Bozen-Bolzano. After his graduation from the University of Padua, Italy, he worked as a teacher of Mathematics at the first level of secondary school. Later, he worked for 10 years in the Education Department of the Province of Bozen-Bolzano (Dipartimento Istruzione e Formazione Italiana) as the coordinator of the FUSS project. The FUSS project installed GNU/Linux in all Italian speaking schools of South Tyrol and promoted the use of new technologies among teachers. The focus of his PhD research fits between computer science education and interaction design. In particular, his PhD research is concerned with the design and development of interactive objects for the scaffolding of graphs and graph algorithmic thinking.

The demystification of the robot: Why we need informed people and explainable machines (in Kooperation mit der JOANNEUM RESEARCH Forschungsgesellschaft mbH ROBOTICS, Klagenfurt)

Univ.-Prof.in Dr.in Martina Mara | November 20, 2018 | 13:00 | HS 2

Abstract:
Robotics and Artificial Intelligence entail many opportunities for humanity: From improving medical diagnoses to enabling greater autonomy for the elderly, from cleaning the house to optimizing energy efficiency. In the public discourse, however, smart technologies are customarily represented by the stereotypical image of the android, the artificial replication of the human being. Based on psychological findings, Mara argues that a human-centered approach towards technological development must foster new visions of complementary human-machine relationships instead of fueling fears of substitution. Furthermore, as many outside the expert circles still lack information about technical functions and feel uncomfortable with technology they don’t understand, there is a need for user empowerment: By explaining basic technological concepts to the public and by designing machines that are explainable themselves.

CV:
Prof. Martina Mara is a leading expert on human-robot relationships and head of the Robopsychology Lab at the Johannes Kepler University Linz. Her team explores how autonomous machines should look like, behave, and communicate in order to establish comfortable interaction experiences for varying target groups. She earned her doctorate at the University of Koblenz-Landau’s Institute for Communication Psychology and Media Education with a dissertation on anthropomorphic machines. She regularly speaks at international conferences and she writes about social impacts of emerging technologies in her weekly tech column „Schöne neue Welt“ („Brave new world“). As a member of the Austrian Council for Robotics, she advices the Austrian government in establishing a strategy for the application of robotics and artificial intelligence.

Low-time complexity workflow application scheduling on heterogeneous systems

Jorge Barbosa, PhD | November 22, 2018 | 2 pm | S.2.69

Abstract:
A heterogeneous system can be defined as a range of different system resources, which can be local or geographically distributed, that are utilized to execute computationally intensive applications. The efficiency of executing parallel applications on heterogeneous systems critically depends on the methods used to define an assignment and mapping of the workflow tasks onto resources.

Scheduling in this context is mainly divided into two main approaches: single and multiple QoS parameters. On the single QoS parameter, the execution time of a workflow application, also called makespan, has been the major concern in most of the scheduling strategies. In this talk, it will be presented a novel algorithm for time optimization that implements a look-ahead feature while keeping a quadratic time complexity.

The problem becomes more challenging when two or more QoS parameters are considered in the scheduling problem. Time, cost, energy and reliability are common QoS parameters considered in recent research work in this area. Many algorithms consider time and cost in their formulation but most of them perform: (a) optimization of one parameter constrained to the other; (b) optimization of both parameters in a bi-objective formulation; and (c) a consideration of an unlimited number of resources, in particular for cloud platforms, where the strategy to accomplish time constraints is by allocating new computational instances.

In this talk two low-time complexity algorithms for QoS based scheduling, bounded to a set of resources, will be addressed. Namely, a time optimization and budget constrained scheduling and a budget-deadline constrained scheduling algorithm.

Research topics on resource management of heterogeneous systems will be discussed, namely, energy-aware scheduling, auto-tuning and concurrent scheduling.

CV:
Jorge Barbosa obtained his MSc degree from the University of Manchester Institute of Science and Technology, in 1993, and the PhD in Electrical and Computer Engineering from Faculdade de Engenharia da Universidade do Porto (FEUP), in 2001. He is Assistant Professor at the Department of Informatics Engineering at FEUP. He has (co-)authored over 60 scientific publications (including journal/conference papers and book chapters) on subjects related to parallel algorithms, resource management, energy-aware scheduling and performance modeling for heterogeneous systems. His current research interests are related to energy-aware scheduling, data locality, auto-parallelization tools and concurrent scheduling. He is member of the Editorial Board of Elsevier Journal „Simulation Modelling Practice and Theory“.
