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.

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.

Abstract:
In the last decade, industrial fabrication of magnetic sensors has greatly improved producing ever cheaper and more reliable sensors. Consequently magnetic sensor systems have been developed for multiple applications that include current sensors, position and orientation sensors, compass applications, geomagnetic survey and others. Specific applications in modern automobiles include e.g. shift fork position detection, speed sensors, ABS sensors, steering wheel angle sensors, gas and break padel sensors and powertrain current sensors.

It is the aim of this lecture to provide a fundamental understanding of the working principles of such sensor systems and to discuss design difficulties. Computer aided design of magnetic sensor systems based on numerical methods and analytical implementations is discussed. Practical examples from industrial projects are shown.

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.

Abstract

In this talk the basics of micro and nano fabrication techniques will be covered. We will discuss in particular how they are carried out in a typical clean room environment. We will learn what are the differences between the front-end and back-end in MEMs microfabrication. There will be a bunch of technical terms in thin film and thick film processing of MEMS, which will be explained briefly.  We then follow up by describing the basics of the various fabrication steps such as thin film formation, lithography as well as etching. Some typical in-line and off-line characterization and testing techniques of thin films will also be introduced.
