Starting High-Tech Environment out of Necessity – Сase of the University of Novi Sad, Serbia

VS020903Guest speakerVojin Šenk, Professor of University of Novi Sad, Chair of Telecommunications and Signal Processing, UNESCO chair of Entrepreneurship

When: September 24, 4 pm

Abstract: The city of Novi Sad, Serbia, has a disproportionately large university and once had a formidable industry. The breakup of Yugoslavia, war, international sanctions, bombardment by NATO forces, mishandled privatization and, lately, world economic crisis have destroyed almost all the traditional industry in the city, the whole province of Vojvodina and Serbia itself. The University of Novi Sad, and especially the Faculty of Engineering as its part, was left without the environment in which to function, without material resources, and, being the second largest city and in opposition to the regime of the nineties, without any support from within during the period. And then, the miracle happened: professors first, than the researchers, and finally students, started opening new knowledge-based companies, mainly in the ICT area, and created a completely new industry, employing thousands, earning hundreds of millions, and turning around the downward trend.

The lesson learnt, i.e. the most important message from this story, is that the time when researchers were just explaining the world and then offering help to those changing it for better is over: it is to those researchers now to change the world themselves. How? Well, some help is needed as well, and we will discuss which, how, and why. Especially which and why not, contrary to conventional bureaucratic wisdom: the technology transfer centers.

Structural material systems: challenges and evolution in design, manufacturing and system integration

Speaker:  Prof. Paolo Gaudenzi, University of Rome “La Sapienza”  paolo-gaudenzi-intervista

When: November 5, 4pm

Abstract:  The design of structural components, once considered only under the domain of mechanical disciplines, has evolved towards multy-phisics behaviour and multy-scale analysis. Manufacturing processes like 3D printing or advanced composite construction have made and will made possible shapes and performances once not conceivable. The “mechanical” component is now more that ever embedded and integrated in complicated systems and acquires itself the nature of a system. The evolution of concurrent design and IoT made the engineering disciplines of mechanics, electronics and informatics become a single area of competences. In a scenario of engineering systems that are facing the challenges of enhances performances and low cost, the colloquium aims at giving some stimulus to a debate on how to better prepare the ground today for the evolution of technologies and of the engineering systems that will meet the needs of the product and services of the future society.

A journey to the land of excited state dynamics in organic semiconductors

image003Speaker:  Prof. Sergei Tretiak, Electrochemical Energy Storage Center, Skoltech, and Theoretical Division, Center for Nonlinear Studies and Center for Integrated Nanotechnologies, Los Alamos National Laboratory, Los Alamos, US  

When: November 12, 4 pm

Abstract: Prediction and understanding of photo-induced processes in molecular- and nano-materials is fundamental to a myriad of technological applications, ranging from sensing, imaging, solar energy harvesting, to future optoelectronic devices.  Hence modelling of non-adiabatic dynamics in extended molecular systems and solids is a next frontier of atomistic electronic structure theory.

Using our recently developed non-adiabatic excited-state dynamics simulations framework, we study ultrafast dynamics and excitation transport in several large molecular systems.  These simulations reveal a fascinating interplay of conformational vibrational dynamics and internal conversion followed photo-excitation, which has specific spectroscopic signatures and can be observed using time-resolved pump-probe spectroscopies. Observed relationships between spatial extent/properties of electronic wave functions and resulting electronic functionalities allow us to understand and to potentially manipulate excited state dynamics and energy transfer pathways in a number of organic molecular materials suitable for a variety of technological applications.

Green energy: New technologies for the production and distribution of power

:  Prof. Volker Mehrmann, Technical University of Berlin, Germany  

When: November 26, 4pm

Abstract:  The huge demand for energy in the world combined with the danger for a major climate change due to too many CO2 emissions has led to a rather rapid change in the technologies for energy conversion, moving away from fossil energies to regenerate energy sources such as wind, solar and geothermic energy. This development has created large difficulties for the development and operation of modern energy networks; the power generation is performed decentralized and has to be. First of all the supply has become rather erratic, due to the dependence on weather conditions. At the same time the difficulties in storing large amounts of electrical energy  leads to new challenges in techniques such as the development of new types of batteries or the conversion of electrical energy into gas which can be stored rather easily. On top of these difficulties, the safety of the supply chain and the influence of the energy markets has to be taken into consideration.

The talk will cover all these issues and show that a global consideration of the complete energy chain can be viewed as huge dynamical systems with multiphysical components. Although still a challenge for current simulation and optimization techniques, mathematical models of global energy are becoming essential in the day-to-day operation of such systems. Jointly with industrial partners, hierarchies of models are created that allow detailed simulation and optimization even under the influence of uncertainties. We present new techniques and demonstrate current challenges and perspectives.

Small Satellite Formations : A Disruptive Technology Challenge for Space Applications

Speaker:  Dr. Klaus Schilling, Professor and klausChair for Robotics and Telematics at University Wuerzburg (Germany), President of the research company “Zentrum für Telematik”

When: December 10, 4 pm

Abstract: Networked distributed systems promise interesting perspectives for multiple small satellites, taking advantage of significant baseline distances. The University Würzburg’s Experimental satellite (UWE) program uses a step by step approach to develop and test in space the crucial technologies for formation flying at minimum necessary mass.

So far all UWE satellites could be realized at 1 kg.  UWE-1 (launched 2005) addressed optimization of internet protocol parameters to the space environment for future satellite network communication. UWE-2 (launched 2009) continued telecommunication experiments on “internet in space” and focused in addition on attitude and orbit determination by miniature sensors and advanced data processing. UWE-3 (launched November 2013) emphasizes a miniature attitude control system (ACS) implementation, based on six magnetic torquers and one very small reaction wheel. An increased reliability for the on-board data handling system was achieved by two low power consumption commercial microprocessors and advanced fault detection, isolation and recovery system software. With respect to spacecraft system design, the modular realization of UWE-3 forms the flexible basis for future multi-satellite formation systems.

The application perspective for the four pico-satellite formation flying mission “NetSat”, being in implementation stage, will be outlined at this Colloquium.
