Du, Tianyu (author)Spiking Neural Networks(SNN) have been widely leveraged by neuromorphic systems due to their ability to closely mimic biological neural behavior, where information is exchanged and received between neurons in the form of sparse events(spikes). Such neuromorphic systems are highly energy-efficient because the use of a global clock can be avoided...master thesis 2023

Yang, Yichen (author)To support the spike propagates between neurons, neuromorphic computing systems always require a high-speed communication link. <br/>Meanwhile, spiking neural networks are event-driven so that the communication links normally exclude the clock signal and related blocks. This thesis aims to develop a self-timed off-chip interconnect system with...master thesis 2022

Jordan, Sebastian (author)In recent years, the large increase in connected devices and the data that is collected by these devices has caused a heightened interest in distributed processing. Many practical distributed networks are of heterogeneous nature. Because of this, algorithms operating within these networks need to be simple, robust against network dynamics and...master thesis 2022

Dubravica, Luka (author)Distributed systems are networks of nodes depending on each other. However, each network can have multiple faulty nodes, which are either malfunctioning or malicious. Bracha's algorithm allows correct nodes inside the network to agree on certain information, while tolerating a certain amount of faulty nodes. Nodes exchange Send, Echo and Ready...bachelor thesis 2022

Striner, Alina (author), Röggla, Thomas (author), Zorrilla, Mikel (author), Cabrero Barros, Sergio (author), Masneri, Stefano (author), Rivas Pagador, Héctor (author), Calvis, Irene (author), Li, Jie (author), Cesar, Pablo (author)Artistic co-creation empowers communities to shape their narratives, however HCI research does not support this multifaceted discussion and reflection process. In the context of community opera, we consider how to support co-creation through the design, implementation, and initial evaluation of the Co-Creation Space (CCS) to help community...conference paper 2022

Pourahmad, Ali (author), Dehghani, Rasoul (author), Ahmadi-Mehr, Seyed Amir-Reza (author), Lotfi, R. (author)Implementation of the DAC is usually the bottleneck in designing a SAR ADC. Here an innovative DAC-less SAR (DLSAR) ADC architecture is presented which alleviates some drawbacks of the conventional SAR counterpart. The proposed DLSAR binary search algorithm is comprised of two arithmetic operations of division-by-two and subtraction to...journal article 2022

YANG, FANG (author)This dissertation describes an approach to building a self-timed asynchronous pulse-mode serial link circuit. Unlike asynchronous handshake circuits or synchronous circuits, this design style does not require any feedback control blocks, which can increase latency, or any clock recovery circuits, which can increase energy consumption and...master thesis 2021

Li, Pai (author)Neuromorphic electronic systems have used asynchronous logic combined with continuous-time analog circuits to emulate neurons, synapses, and learning algorithms. It is attractive because of its low power consumption and feasible implementation. Typically, the neuron firing rates are lower than the modern digital systems. Thus, the endpoints of...master thesis 2021

Meyer, Johann (author)Aircraft are complex systems with, in some cases, high-dimensional nonlinear interactions between control surfaces. When a failure occurs, adaptive flight control methods can be utilised to stabilise and make the aircraft controllable. Adaptive flight control methods, however, require accurate aerodynamic models - where first-order continuity is...master thesis 2021

Ananduta, W. (author), Nedic, Angelia (author), Ocampo-Martinez, Carlos (author)A multi-agent optimization problem motivated by the management of energy systems is discussed. The associated cost function is separable and convex although not necessarily strongly convex and there exist edge-based coupling equality constraints. In this regard, we propose a distributed algorithm based on solving the dual of the augmented...journal article 2021

Eland, E.N. (author), Karmakar, S. (author), Gonen, B. (author), van Veldhoven, Robert (author), Makinwa, K.A.A. (author)This article describes a discrete-time zoom analog-to-digital converter (ADC) intended for audio applications. It uses a coarse 5-bit SAR ADC in tandem with a fine third-order delta-sigma modulator (ΔΣM) to efficiently obtain a high dynamic range. To minimize its over-sampling ratio (OSR) and, thus, its digital power consumption, the...journal article 2021

Bonomi, Silvia (author), Decouchant, J.E.A.P. (author), Farina, Giovanni (author), Rahli, Vincent (author), Tixeuil, Sébastien (author)In this paper, we consider the Byzantine reliable broadcast problem on authenticated and partially connected networks. The state-of-the-art method to solve this problem consists in combining two algorithms from the literature. Handling asynchrony and faulty senders is typically done thanks to Gabriel Bracha's authenticated double-echo...conference paper 2021

Cenedese, Carlo (author), Belgioioso, Giuseppe (author), Grammatico, S. (author), Cao, Ming (author)In this paper, we present three distributed algorithms to solve a class of Generalized Nash Equilibrium (GNE) seeking problems in strongly monotone games. The first one (SD-GENO) is based on synchronous updates of the agents, while the second and the third (AD-GEED and AD-GENO) represent asynchronous solutions that are robust to communication...journal article 2021

Çalış, M. (author), Heusdens, R. (author), Hendriks, R.C. (author)Average consensus algorithms are used in many distributed systems such as distributed optimization, sensor fusion and the control of dynamic systems. Consensus algorithms converge through an explicit exchange of state variables. In some cases, however, the state variables are confidential. In this paper, a privacy-preserving asynchronous...conference paper 2020

Çalış, Metin (author)Consensus problem has been a topic of interest for many research areas allowing multiple agents to reach an agreement through local information exchange. The explicit share of the state variables, however, may cause privacy issues due to the confidentiality of the initial values.

Uijtewaal, Prescilla (author)The principal function of neurons in the cortex is to communicate and process information. A characteristic of this communication is the high trial-to-trial spike variability. To explain this variability, balanced network models have been introduced. The interaction between excitatory and inhibitory neurons in those models, can perform active...master thesis 2019
