Embracing Fairness in Consumer Electricity Markets using an Automatic Market Maker
Shaun Sweeney, Chris King, Mark O'Malley +1
As consumer flexibility becomes expected, it is important that the market mechanisms which attain that flexibility are perceived as fair. We set out fairness issues in energy marke…
Tree Proof-of-Position Algorithms
Aida Manzano Kharman, Pietro Ferraro, Homayoun Hamedmoghadam +1
We present a novel class of proof-of-position algorithms: Tree-Proof-of-Position (T-PoP). This algorithm is decentralised, collaborative and can be computed in a privacy preserving…
Quantifying indirect and direct vaccination effects arising in the SIR model
Lixin Lin, Homayoun Hamedmoghadam, Robert Shorten +1
Vaccination campaigns have both direct and indirect effects that act to control an infectious disease as it spreads through a population. Indirect effects arise when vaccinated ind…
Reinforcement Learning with Adaptive Regularization for Safe Control of Critical Systems
Haozhe Tian, Homayoun Hamedmoghadam, Robert Shorten +1
Reinforcement Learning (RL) is a powerful method for controlling dynamic systems, but its learning mechanism can lead to unpredictable actions that undermine the safety of critical…
An attack resilient policy on the tip pool for DAG-based distributed ledgers
Lianna Zhao, Andrew Cullen, Sebastian Müller +2
This paper discusses congestion control and inconsistency problems in DAG-based distributed ledgers and proposes an additional filter to mitigate these issues. Unlike traditional b…
Robust decentralised proof-of-position algorithms for smart city applications
Aida Manzano Kharman, Pietro Ferraro, Anthony Quinn +1
We present a decentralised class of algorithms called Tree-Proof-of-Position (T-PoP). T-PoP algorithms rely on the web of interconnected devices in a smart city to establish how li…
On Unique Ergodicity Of Coupled AIMD Flows
Pietro Ferraro, Jia Yuan Yu, Ramen Ghosh +4
The AIMD algorithm, which underpins the Transmission Control Protocol (TCP) for transporting data packets in communication networks, is perhaps the most successful control algorith…
Fairness in Forecasting of Observations of Linear Dynamical Systems
Quan Zhou, Jakub Marecek, Robert N. Shorten
In machine learning, training data often capture the behaviour of multiple subgroups of some underlying human population. This behaviour can often be modelled as observations of an…
Respiratory Aware Routing for Active Commuters
Abigail Langbridge, Pietro Ferraro, Robert Shorten
Cyclists travelling in urban areas are particularly at risk of harm from particulate emissions due to their increased breathing rate and proximity to vehicles. In this paper we com…
Herd Routes: A Preventative IoT-Based System for Improving Female Pedestrian Safety on City Streets
Madeleine Woodburn, Wynita M. Griggs, Jakub Marecek +1
Over two thirds of women of all ages in the UK have experienced some form of sexual harassment in a public space. Recent tragic incidents involving female pedestrians have highligh…
Spatial Positioning Token (SPToken) for Smart Parking
Roman Overko, Rodrigo Ordóñez-Hurtado, Sergiy Zhuk +1
In this paper, we describe an approach to guide drivers searching for a parking space (PS). The proposed system suggests a sequence of routes that drivers should traverse in order…
An adversarially robust data-market for spatial, crowd-sourced data
Aida Manzano Kharman, Christian Jursitzky, Quan Zhou +4
We describe an architecture for a decentralised data market for applications in which agents are incentivised to collaborate to crowd-source their data. The architecture is designe…
A DLT enabled smart mask system to enable social compliance
Lianna Zhao, Pietro Ferraro, Robert Shorten
As Covid-19 remains a cause of concern, especially due to its mutations, wearing masks correctly and efficiently remains a priority in order to limit the spread of the disease. In…
Feedback control for distributed ledgers: An attack mitigation policy for DAG-based DLTs
Pietro Ferraro, Andreas Penzkofer, Christopher King +1
In this paper we present a feedback approach to the design of an attack mitigation policy for DAG-based Distributed Ledgers. We develop a model to analyse the behaviour of the ledg…
On the Ergodic Control of Ensembles in the Presence of Non-linear Filters
Vyacheslav Kungurtsev, Jakub Marecek, Ramen Ghosh +1
In many sharing-economy applications, as well as in conventional economy applications, one wishes to regulate the behaviour of an ensemble of agents with guarantees on both the reg…
Predictability and Fairness in Load Aggregation and Operations of Virtual Power Plants
Jakub Marecek, Michal Roubalik, Ramen Ghosh +2
In power systems, one wishes to regulate the aggregate demand of an ensemble of distributed energy resources (DERs), such as controllable loads and battery energy storage systems.…
Subgroup Fairness in Two-Sided Markets
Quan Zhou, Jakub Marecek, Robert N. Shorten
It is well known that two-sided markets are unfair in a number of ways. For instance, female workers at Uber earn less than their male colleagues per mile driven. Similar observati…
Unique Ergodicity in the Interconnections of Ensembles with Applications to Two-Sided Markets
Wynita M. Griggs, Ramen Ghosh, Jakub Marecek +1
There has been much recent interest in two-sided markets and dynamics thereof. In a rather a general discrete-time feedback model, which we show conditions that assure that for eac…
Predictability and Fairness in Social Sensing
Ramen Ghosh, Jakub Marecek, Wynita M. Griggs +2
We consider the design of distributed algorithms that govern the manner in which agents contribute to a social sensing platform. Specifically, we are interested in situations where…
Fairness in Forecasting and Learning Linear Dynamical Systems
Quan Zhou, Jakub Marecek, Robert N. Shorten
In machine learning, training data often capture the behaviour of multiple subgroups of some underlying human population. When the amounts of training data for the subgroups are no…
Augmented Reality, Cyber-Physical Systems, and Feedback Control for Additive Manufacturing: A Review
Hugo Lhachemi, Ammar Malik, Robert Shorten
Our objective in this paper is to review the application of feedback ideas in the area of additive manufacturing. Both the application of feedback control to the 3D printing proces…
Distributed Ledger Technology, Cyber-Physical Systems, and Social Compliance
Pietro Ferraro, Christopher King, Robert Shorten
This paper describes how Distributed Ledger Technologies can be used to design a class of cyber-physical systems, as well as to enforce social contracts and to orchestrate the beha…
Distributed Multi-resource Allocation with Little Communication Overhead
Syed Eqbal Alam, Robert Shorten, Fabian Wirth +1
We propose a distributed algorithm to solve a special distributed multi-resource allocation problem with no direct inter-agent communication. We do so by extending a recently intro…
A context-aware e-bike system to reduce pollution inhalation while cycling
Shaun Sweeney, Rodrigo Ordonez-Hurtado, Francesco Pilla +3
The effect of transport-related pollution on human health is fast becoming recognised as a major issue in cities worldwide. Cyclists, in particular, face great risks, as they typic…
