Abstract: The impact of climate change to biosphere and the human civilization living therein are widely discussed as is the need to reduce the consumption of energy and materials – measured in footprints. Despite of that the means on how to reduce footprints and the difficulties going along with that are lesser discussed.
The assessment of CO2 Footprints during all phases of its production and existence (Life Cycle Assessment) is embedded in the legally required of non-financial reporting for companies. This talk is intended to provide background on non-financial reporting and how that relates to footprints and risks. Of course reporting is not l´art pour l´art. It is intended to reduce the impact of an activity – Ecodesign and it impacts the value of companies. The intent is to discuss in more detail how reporting is done, how (CO2-) Footprints are derived, ways to reduce footprints and how the related activities influence the value of companies.

Abstract: Radio waves carry both energy and information simultaneously. Nevertheless, radio-frequency (RF) transmissions of these quantities have traditionally been treated separately. Future wireless networks will experience a paradigm shift, namely, unifying wireless transmission of information and power to make the best use of the RF spectrum and radiation as well as the network infrastructure for the dual purpose of communicating and energizing. Such networks will enable trillions of future low-power devices to sense, compute, connect, and energize anywhere, anytime, and on the move. The design of such future networks brings new challenges and opportunities for RF, communications, signal processing, machine learning, sensing, and computing. In this talk, I give an overview progress in laying the foundations of the envisioned dual-purpose networks by establishing a signal theory and design for wireless information and power transmission (WIPT) and identifying the fundamental tradeoff between conveying information and power wirelessly.

Abstract: Empowered by today’s rich tools for media generation and collaborative production and convenient network access to the Internet, video streaming has become very popular. Dynamic adaptive video streaming is a technique used to deliver video content to users over the Internet, where the quality of the video adapts in real time based on the network conditions and the capabilities of the user’s device. HTTP Adaptive Streaming (HAS) has become the de-facto standard to provide a smooth and uninterrupted viewing experience, especially when network conditions frequently change. Improving the QoE of users concerning various applications‘ requirements presents several challenges, such as network variability, limited resources, and device heterogeneity. For example, the available network bandwidth can vary over time, leading to frequent changes in the video quality. In addition, different users have different preferences and viewing habits, which can further complicate live streaming optimization. Researchers and engineers have developed various approaches to optimize dynamic adaptive streaming, such as QoE-driven adaptation, machine learning-based approaches, and multi-objective optimization, to address these challenges. In this talk, we will give an introduction to the topic of video streaming and point out the significant challenges in the field. We will present a layered architecture for video streaming and then discuss a selection of approaches from our research addressing these challenges. For instance, we will present approaches to improve the  QoE of clients in User-generated content applications in centralized and distributed fashions. Moreover, we will present a novel architecture for low-latency live streaming that is agnostic to the protocol and codecs that can work equally with existing HAS-based approaches.

Abstract: In recent years, we have experienced an exponential growth in the amount of data generated by IoT devices. Data have to be processed strict low latency constraints, that cannot be addressed by conventional computing paradigm and architectures. On top of this, if we consider that we recently hit the limit codified by the Moore’s law, satisfying low-latency requirements of modern applications will become even more challenging in the future. In this talk, we discuss challenges and possibilities of heterogeneous distributed systems in the Post-Moore era.
