A new approach to driving cycle development and its applications
Pattison, Timothy (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)Driving cycles describe the general driving pattern of a vehicle in a road network, and are usually represented by speed-time profiles of equal spacing. They are used to approximate and represent driving conditions as an ... -
A study on the deployment and acceleration of low carbon technologies
Kennedy, Matthew (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)The work presented in this thesis is an investigation into the variables that are considered by consumers when selecting low carbon technologies (LCT) and the barriers that are encountered by implementers when deploying ... -
Application of time-series and wavelet analysis for traffic flow modelling and incident detection
Ghosh, Bidisha (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2007)Efficient and sustainable use of existing transportation network has become a major issue in socio-economic growth of the developed parts of today’s world. Intelligent Transportation System (ITS) is an important tool to ... -
Design of an active compliant liquid column damper by LQR and wavelet linear quadratic regulator control strategies
Basu, Biswajit; Bhattacharyya, Soumi; Ghosh, Aparna Dey (2018)A new active tuned liquid column damper is developed for seismic vibration control of structures by employing the configuration of the compliant liquid column damper (CLCD). This control system is referred to as the active ... -
Dynamic response of Spar-type Floating Offshore Wind
Nguyen, Hoa XuanFloating offshore wind turbines (FOWTs) are an alternative technology to harness the abundant wind energy in open sea areas. A FOWT structure consists of a floating platform, a mooring system, and a wind turbine structure ... -
Dynamics of wind turbines including soil-structure interaction
Harte, Michael (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2012)This thesis investigates the dynamic response of Horizontal Axis Wind Turbines (HAWT) including Soil-Structure Interaction (SSI) effects. Multi- Degree-of-Freedom (MDOF) HAWT models are proposed for dynamic analysis using ... -
Flow in a large wind field with multiple actuators in the presence of constant vorticity
Fitzgerald, Breiffni; Basu, Biswajit; Soodhalter, Kirk (2022)Study of wind farms is an area of active research. Researchers have proposed simplified wind farm models which define the wake structure in a wind farm and how they affect the performance of the wind turbines. Interestingly ... -
Identification and evolutionary response analysis of continuous and discrete structural systems using wavelet transform
Chakraborty, Arunasis (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2006)Performance based design of structures require stringent serviceability criteria to be satisfied based on functional requirements and economic implications. Thus, performance evaluation of structural dynamic systems not ... -
Individual Blade Pitch Control of Floating Offshore Wind Turbines for Load Mitigation and Power Regulation
Fitzgerald, Breiffni; Basu, Biswajit; Sarkar, Saptarshi (2020)This paper proposes a new strategy for individual blade pitch control to regulate power production while simultaneously alleviating structural loads on spar-type floating offshore wind turbines. Individual blade pitch ... -
Investigation on autonomous healing for GFRP composite using cyanoacrylate adhesives
Fifo, Omosola (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2012)An investigation into smart structures with a vascular healing system using cyanoacrylate (CA) adhesive is presented in this thesis. The flexibility in the functional role of a smart structure involves the structure executing ... -
Nonlinear model predictive control to reduce pitch actuation of floating offshore wind turbines
Fitzgerald, Breiffni; Basu, Biswajit (2020)Modern-day wind turbines use active pitch control to reduce mechanical loads on the turbines in addition to regulating generator power. These control algorithms increase blade pitch actuation, primarily to reduce the 1P ... -
Optimal Control Algorithms for Wave Energy Conversion
Politi, Giacomo (Trinity College Dublin. School of Engineering.
