Web search services have become a fundamental tool used by governments, businesses, and individuals, and play a key role in our access to knowledge and information. In this project we aim to develop new techniques for representing the indexes at the heart of web search services, and to devise new processing algorithms with reduced resource requirements for resolving queries and providing useful and topical answers. Higher query throughput and reduced storage load will benefit providers though reduced hardware and electricity costs, and will benefit society through better access to information, enhanced opportunities to connect and collaborate, and greater long-term scalability as on-line resources continue to multiply.Read moreRead less

This project aims to design low-power consuming coding schemes that can achieve the maximum coding gain for NAND Flash memories in Solid State Drives. Although these devices are replacing hard drives in laptops and provide enormous benefits in access speed and weight, they become unreliable the more they are used. Advanced coding techniques are needed to solve problems caused by the very strict reliability/cost requirements of large storage systems. Allocating memory to coding redundant information can extend these devices’ lifetime. The design of codes and decoders with a low power consumption is expected to be the key enabling technology for next generation large storage devices.Read moreRead less

Advanced coding techniques for fast failure recovery in storage systems. This project aims to improve the performance of distributed data storage systems during the recovery of node-failures using advanced repair techniques for the underlying erasure coding schemes. Reed-Solomon codes, employed in most of current storage systems, for example Google Colossus, Baidu's Atlas, Yahoo Object Store, and Facebook's f4, require extremely high network bandwidth and disk I/O for failure recovery.

The project aims to investigate the application of error-control coding theory in blockchains, focusing on reducing the storage, computation, and communication overheads, as well as increasing the throughput of blockchain networks. The ambition is to develop coding theory in a completely new territory: decentralised, untrusted, and peer-to-peer networks. The intended outcome is to greatly extend the current state of the art of the theory of error-control codes, previously investigated only in the context of centralised architectures, where a server coordinates every task. Practically, the project should provide significant benefits in terms of cost-effectiveness of blockchains, increase in their processing speed, and security enhancement. Read moreRead less

The project aims to develop new bandwidth-efficient index coding schemes to reduce network congestion. A large portion of the increasing internet traffic is due to video content browsing and distribution. This creates serious strains on the current network infrastructure, which is designed to support conventional data. It is crucial to explore new avenues to reduce the network congestion due to large file downloads. The project aims to tackle this problem by exploring new index coding techniques that are robust to failures in wireless and wired network links. Using advanced mathematical tools from algebraic number theory and module theory, the project aims to design optimally bandwidth-efficient index coding schemes that enable timely and reliable content distribution to end users.Read moreRead less
