SRMAP Departmental Events

As a part of the departmental Distinguished Lecture Series, the Department of Electronics and Communication Engineering at SRM University-AP is organising the first lecture on the topic “Queueing theoretic models for wireless multicast systems and power control via deep reinforcement learning”. Dr Vinod Sharma, Professor in Electrical Communication Engineering, IISc, Bangalore will be the keynote speaker of the session which will be held on July 29, 2021, at 4.00 pm.

Abstract:
We consider a wireless Base station (BS) transmitting on a downlink to multiple users. The BS has a finite number of files that the users can request. The users may have their own local caches. If a user requests a file and it is not in its cache, the request goes to the BS. This model is the practical scenario of downloading/streaming videos from Netflix. In order to reduce the transmission load on the downlink, we exploit the fact that the downlink is a broadcast channel and multiple users may be requesting the same file. This is accomplished by designing a novel multicast scheme in which all requests at the BS for the same file are merged together and are satisfied by a single transmission from the BS. This simple and natural scheme is shown to provide lower mean sojourn time compared to the currently popular coded caching schemes in literature and is much simpler to implement. We have also theoretically studied this queue and obtained approximate mean sojourn times. Next, we have shown that considering the channel fading can actually wipe out most of the benefits of our multicast scheme. However, we suggest a simple modification to the scheme which restores most of the gains. Furthermore, we show that adaptively changing the transmit power at the BS based on the instantaneous channel gains of the users can further significantly reduce the mean sojourn times. To get optimal power control, we use DQN, a Deep Reinforcement Learning algorithm. It is modified to ensure that the long term power constraint is satisfied and that it tracks the time-varying channel and request statistics.

The latest episode of the webinar series conducted by the Department of Biological Sciences in SRM University-AP is scheduled for July 31, 2021, at 11.00 am. Dr Rajan Sankaranarayanan, Chief Scientist at CSIR-Centre for Cellular and Molecular Biology (CCMB) will give a lecture on the topic “X-ray vision on ‘Chiral Checkpoints’ during protein biosynthesis” in the session. Faculty and research scholars from the department will join the speaker on the panel.

Protein chains contain only l-amino acids, with the exception of the achiral glycine, making the chains homochiral. This homochirality is a prerequisite for proper protein folding and, hence, normal cellular function. As a scientist, Dr Sankaranarayanan comprehensively reviews d-amino acids with respect to their occurrence and physiological roles, implications for chiral checkpoints required for translation fidelity, and potential use in synthetic biology. He has co-authored and published a research paper titled “Chiral checkpoints during protein biosynthesis” in the “Journal of Biological Chemistry”.
