Time is a well-known concept for everyone. It is also the SI-unit that we humans can measure with the highest accuracy and precision. This makes it particular interesting for various applications such as navigation and fundamental physics. In this talk I will introduce the basic concept of metrology and the current and the presumed future SI-system. I will then present an overview of the history of time measurements before introducing the Nobel Prize winning concepts and techniques, such as laser cooling and frequency combs, and how these techniques have been utilized to build so-called optical atomic clocks that neither will gain nor lose a second during the lifetime of our universe. Finally I will discuss the potential everyday applications for such clocks.
Martin Zelan has background in laser physics and holds a Ph.D from Umeå University (2011). Between 2011 and 2012 he worked at the National Institute of Standards and Technology (NIST) in the group of Nobel laureate Bill Phillips, where he investigating the possibility to use laser cooled atoms for quantum information applications. Since 2012 he holds a position at the Swedish National Metrology Institute at SP in Borås as a researcher and project leader.

With the introduction of the fourth generation (4G) of wireless equipment almost complete, the focus of the research community has switched to the fifth generation, targeted for commercialisation in 2020. Increased data rates, a renewed focus on the internet-of-things and the scarcity of spectrum will force operators into higher frequency bands despite deteriorating performance in terms of coverage. The new mm-wave bands under consideration offer both the opportunity for wider bandwidths and the challenge of providing the coverage. Repeaters might be necessary to extend coverage zones. A number of research organisations are doing measurements to better understand how the mm-wave bands behave in different environments. The presentation will describe the mm-wave measurement program currently underway at Victoria University, which aims to identify performance issues under local conditions.

As people spend more time online and invest more of themselves in virtual communities and relationships, they become increasingly entangled with the digital material that results from their online activities. Who they are, what they can do and who they can become is inextricably intertwined with the identities their virtual bodies (e.g., emails, texts, images, videos, profiles and avatars) afford. They are cyborgs, that is, human beings whose bodies and identities are inextricably intertwined with and extended through technology.

Emotional communication is a key component of everyday social interactions, and it can even be crucial for survival (e.g., by signaling the presence of an imminent threat). Fortunately, our brains are equipped with the necessary machinery to rapidly and accurately decode other people's emotional expressions. In this talk I present findings from our group (and others) exploring neural responses to emotional and social stimuli in the visual (facial and body expressions) and auditory ( voice and music) modalities, using neuroimaging approaches.

The talk surveys what happens when computability theory is integrated with concurrency theory, which theorems remain valid and which theorems should be adapted. The Reactive Turing Machine is introduced as a model of computability with interaction. About Jos Beaten. (pdf, 52.1 kB)
