Design and optimization of a Holweck pump via linear kinetic theory
(2012)The Holweck pump is widely used in the vacuum pumping industry. It can be a self standing apparatus or it can be part of a more advanced pumping system. It is composed by an inner rotating cylinder (rotor) and an outer ... -
Development of an equivalent static method for the approximation of the dynamic response of offshore structures
(2019)Purpose: The design of compliant towers in deep waters is greatly affected by their dynamic response to wave loads as well as by the geometrical and material nonlinearities that appear. In general, a nonlinear time history ... -
Estimating the Relative Speed of RF Jammers in VANETs
(2019)Vehicular Ad Hoc Networks (VANETs) aim at enhancing road safety and providing a comfortable driving environment by delivering early warning and infotainment messages to the drivers. Jamming attacks, however, pose a significant ... -
Finite element model validation and predictions using dynamic reduction techniques
(2011)Finite element (FE) model updating and validation techniques are formulated as single and multi-objective optimization problems. A multi-objective optimization framework results in multiple Pareto optimal models that are ... -
Heuristics for tile parallelism in HEVC
(2017)HEVC has emerged as the new video coding standard promising increased compression ratios compared to its predecessors. This performance improvement comes at a high computational cost. For this reason, HEVC offers three ... -
Multimodal optimization using niching differential evolution with index-based neighborhoods
(2012)A new family of Differential Evolution mutation strategies (DE/nrand) that are able to handle multimodal functions, have been recently proposed. The DE/nrand family incorporates information regarding the real nearest ... -
On the forward in time solution of the unsteady adjoint equations
(2014)A new algorithm for the solution of the unsteady adjoint equations is proposed in this paper aiming at overcoming the excessive computational cost and memory requirements of the conventional adjoint approach for the ... -
Online damage detection in plates via vibration measurements
(2015)In this work, we propose a new framework for the online detection of damage in plates via vibration measurements. To this end, a finite element model of the plate is handled by a recursive Bayesian filter for simultaneous ... -
Reconsideration of the implicit boundary conditions in pressure driven rarefied gas flows through capillaries
(2019)The pressure driven rarefied gas flow through plane channels and tubes of various lengths is solved in a wide range of the gas rarefaction parameter by implementing the implicit boundary conditions for the incoming ... -
RLAC: Random Line Approximation Clustering
(2021)We explore how Random Projections can be used as an Approximate method for Projection Pursuit Clustering in high dimensional data. Traditional data transformations such as PCA for dimensionality reduction have been shown ... -
Target Tracking with Multi-rotor Aerial Vehicles based on a Robust Visual Servo Controller with Prescribed Performance
(2020)In this paper, we present an image-based visual servo control scheme for tracking a moving target using a multirotor aerial vehicle. The proposed scheme is based on the prescribed performance control notion and it is able ... -
A two-step back–forth algorithm for the solution of the unsteady adjoint equations
(2016)A new algorithm for the solution of the unsteady adjoint equations is proposed in this article, aiming at overcoming the excessive computational cost and memory requirements of the conventional adjoint approach for the ... -
Variational restricted Boltzmann machines to automated anomaly detection
(2022)Data-driven methods are implemented using particularly complex scenarios that reflect in-depth perennial knowledge and research. Hence, the available intelligent algorithms are completely dependent on the quality of the ... -
Viability analysis of a decentralized energy market based on blockchain
(2018)This paper considers the design, the development and the experimental evaluation, of a blockchain based smart contract specifying the operating rules of a real time, uniform-price double auction energy market. Producers ...
