Architecture of a decentralised decision support system for futuristic beehives

Francesco Mondada, Robert Thomas Edmund Mills, Robert Matthew Mills

Honeybees are essential to human society, providing pollination services globally as well as producing honey and other valuable products. Effective management of apiaries should not only rely on beekeeper knowledge and skill, but also incorporate new infor ...

Time vs. Truth: Age-Distortion Tradeoffs and Strategies for Distributed Inference

Yunus Inan

In 1948, Claude Shannon laid the foundations of information theory, which grew out of a study to find the ultimate limits of source compression, and of reliable communication. Since then, information theory has proved itself not only as a quest to find the ...

Consensus Control for Decentralized Deep Learning

Martin Jaggi, Tao Lin, Sebastian Urban Stich, Anastasiia Koloskova, Lingjing Kong

Decentralized training of deep learning models enables on-device learning over networks, as well as efficient scaling to large compute clusters. Experiments in earlier works reveal that, even in a data-center setup, decentralized training often suffers fro ...

Microfluidics and cell-free synthetic biology in the development of new diagnostic and therapeutic platforms

Grégoire Michielin

In phenylketonuria, absence or malfunction of the phenylalanine hydroxylase enzyme results in toxic accumulation of phenylalanine in the body. An injectable recombinant enzyme therapy was recently approved and has the potential to improve the quality of li ...

Linear Speedup In Saddle-Point Escape For Decentralized Non-Convex Optimization

Ali H. Sayed, Stefan Vlaski

Under appropriate cooperation protocols and parameter choices, fully decentralized solutions for stochastic optimization have been shown to match the performance of centralized solutions and result in linear speedup (in the number of agents) relative to no ...

Centralized and Decentralized Electricity Markets: Assessment of Operational and Economic Aspects

Sidi-Rachid Cherkaoui, Farzaneh Abbaspourtorbati, Anneta Matenli

This paper presents the comparison of decentralized and centralized market settings in terms of economic efficiencies, particularly price signals, and operating aspects. The decentralized dispatch consists of an energy auction separated from a contingency ...

On the inter-area optimal voltage and reactive power control

Sidi-Rachid Cherkaoui, Omid Alizadeh Mousavi

Scheduling voltage and reactive power is one of the major problems and concerns of the Transmission System Operators (TSOs) especially after deregulation of power market. Due to locally provision of the reactive power resources, each TSO has developed its ...

Centralized Versus Decentralized Control - A Solvable Stylized Model in Transportation

Olivier Gallay

To analyze the potential outcomes resulting from interaction between autonomous decision-making "smart parts" in logistics networks, we propose here an exactly solvable stylized model that is able to quantify how much the dynamics can be enhanced by (fully ...

Centralized Versus Decentralized Control - A Solvable Stylized Model in Transportation

Olivier Gallay

Today's supply networks consist of a certain amount of logistics objects that are enabled to interact with each other and to decide autonomously upon their next steps: in other words, they exhibit a certain degree of autonomous cooperation. Therefore, mode ...

Distribution management system including dispersed generation and storage in a liberalized market environment

Elvira Kägi-Kolisnychenko

Distribution systems are now fundamentally changing. This is due to the fact that a lot of small size dispersed generation units (DG) are expected to be installed at the distribution level, that is, in the medium voltage (MV) and low voltage (LV) networks ...

Multi-agent modelling of electricity markets : transaction processes and generation capacity expansion under competition

Abdelaziz Lahlou

This thesis describes the development of three conceptual models built to serve as decision support tools in liberalised electricity markets. The introduction of competition, higher uncertainty and decentralised planning requires new planning and analysis ...

Distributed link-based ranking in P2P Web retrieval

Jie Wu

One of the main differences between modern search engines and traditional ones is the adoption of link-based ranking algorithm in ordering Web documents. Google has claimed that it is its link-based ranking algorithm, PageRank that has made the quality of ...
