Abstract :

 Bitcoin was an attempt to create a widely used decentralized, autonomous digital currency, that utilizes a set of computer algorithms and dissociated from any of the nation state. In reality, it is a digital and a scarce commodity. This talk will discuss the nature of the Bitcoin, the technical details behind its decentralization and the scarcity. It will also discuss the view of the state actors towards the Bitcoin, its evolution in market place and speculate on its future evolution.

Abstract :

If you enjoy testing the resistance of your interlocutor to non-scientific claims and wrong predictions, ask him to compare the brain and the machine. He might do better if he is not a scientist, but only moderately so. The talk will be by a control theorist, who does not know much about the brain and even less about the computer, but is fascinated by the concept of feedback, both in natural and artificial systems. Feedback is the concept that shaped the development of cybernetics, a discipline that sought to model the brain as a machine. Eventually cybernetics led to the invention of the computer, which became in turn a model for the brain, and turned cybernetics into history. But "cyber" recently reentered the technological hype. A feedback effect?

Abstract :

The evolution of cellular networks is driven by the dream of ubiquitous wireless connectivity: Any data service is instantly accessible everywhere. With each generation of cellular networks, we have moved closer to this wireless dream; first by delivering wireless access to voice communications, then by providing wireless data services, and recently by delivering a WiFi-like experience with wide-area coverage and user mobility management. The support for high data rates has been the main objective in recent years, as seen from the academic focus on sum-rate optimization and the efforts from standardization bodies to meet the peak rate requirements specified in IMT-Advanced. In contrast, a variety of metrics/objectives are put forward in the technological preparations for 5G networks: higher peak rates, improved coverage with uniform user experience, higher reliability and lower latency, better energy efficiency, lower-cost user devices and services, better scalability with number of devices, etc. These multiple objectives are coupled, often in a conflicting manner such that improvements in one objective lead to degradation in the other objectives. Hence, the design of future networks calls for new optimization tools that properly handle the existence and tradeoffs between multiple objectives.

Abstract :

Integrated circuits and devices revolutionized particle physics experiments, and have been a cornerstone in the recent discovery of the Higgs boson by the ATLAS and CMS experiments at the Large Hadron Collider at CERN. Particles are accelerated and brought into collision at specific interaction points. Detectors are giant cameras, about 40 m long by 20 m in diameter, constructed around these interaction points to take pictures of collision products as they fly away from the collision point. They contain millions of channels, often implemented as reverse biased silicon pin diode arrays covering areas of up to 200 m2 in the center of the experiment, generating a small (~1fC) electric charge upon particle traversals. Integrated circuits provide the readout, and accept collision rates of about 40 MHz with on-line selection of potentially interesting events before data storage. The presentation will cover some of the design challenges of these detectors and integrated circuits and also the trend to integrate both in one piece of silicon to meet requirements of particle physics experiments and to help advance our understanding of nature.
