Polls and the US Presidential elections

Did the polls get it wrong? Polls, models and forecasting in the 2020 USA Presidential elections

Pre-election polls and models had anticipated a comfortable victory for Joe Biden. However, it took several days to confirm that de Democratic Presidential candidate had crossed the threshold of 270 delegates. The uncertainty about the final election outcome has spread the feeling that the pre-election polls failed again. The preliminary analysis of the 2020 polls performance shows that most of the national polls were within the expected margin of error. Nevertheless, in some states the voting estimates deviate more than what it would be desirable from the final results. In this presentation I analyse possible reasons that explain the deviation between the polls and the final results.

Statistical controversies: sampling and quantification

Sociology of Statistical Controversies

In this presentation, I will talk about the topic of my research, its rationale, methodology, and some preliminary findings. In different case studies, this research investigates different disputes over method in statistics, such as a controversy regarding the justification for inference from non-probability samples. As part of this research, I conduct interviews with statisticians and other stakeholders to get insights into their interpretations and perspectives towards these controversies. The presentation will explore why sociological and philosophical inquiry into the field of statistics is of crucial relevance for our time and how it can help to better understand current developments.

Tech company responsibility during Covid-19

The responsibility of tech companies during Covid-19 and beyond

Technology companies have been playing a key role during COVID-19 from assisting state responses to improving quality of life during lockdown. These companies are providing means of communication, work, education, social and cultural life that would otherwise be impossible. As tech companies are now playing an essential facilitating role in enabling human rights in this way, a key question emerges: Should tech companies facilitating essential services bear special responsibilities?

Full-Duplex Communication Systems

With exponential increase in data, the need for higher data capabilities in communication system and mobile network in 5G and 6G is inevitable. Full-duplex communication system has the capability to double the bandwidth by transmitting and receiving in the same frequency band at the same time.

In this presentation, potential and challenges of full-duplex communication systems will be considered. Self-interference as the main challenge and various methods to suppress this effect, at different stage including antenna and digital will be reviewed. Some novel techniques will be introduced considering polarisation and antenna structure, in addition to different component, feeding network and surfaces to this end.
