Modeling and nonlinear model predictive control of a subsea pump station
(Journal article; Peer reviewed, 2017)In this paper we present a model of a pump station consisting of two pumps in parallel with a recycle line, and a nonlinear Model Predictive Control strategy for said pump station with suction pressure as the controlled ... -
Modeling and Optimization of Simultaneous Waste Heat Utilization and Wastewater Treatment Processes
(Chapter, 2019)Huge amounts of low-temperature waste heat, which can be utilized to improve the energy efficiency in various ways, are available in the process industries. Organic Rankine Cycle (ORC) is one of the promising technologies ... -
Modeling and Path-following for a snake robot with active wheels
(Chapter; Peer reviewed, 2009)Snake robots with active wheels provide interesting opportunities within many areas such as inspection and maintenance and search and rescue operations. The highly-articulated body of a snake robot combined with the ... -
Modeling and Prediction of Regular Ionospheric Variations and Deterministic Anomalies
(Journal article; Peer reviewed, 2020)Knowledge on the ionospheric total electron content (TEC) and its prediction are of great practical importance and engineering relevance in many scientific disciplines. We investigate regular ionospheric anomalies and TEC ... -
Modeling and Predictive Control of Shipboard Hybrid DC Power Systems
(Peer reviewed; Journal article, 2020)Although onboard DC power systems bring values for the power and propulsion system of the future hybrid ships, the main barrier for the development of such systems for large scale vessels is the technical operational issues ... -
Modeling and Propulsion Methods of Underwater Snake Robots
(Chapter, 2017)In this paper we consider underwater snake robots (USRs) that may be equipped with additional added effectors along their body, including caudal, dorsal and pectoral fins, tunnel thrusters and/or a stern propeller. We ... -
Modeling and Provisioning Highly Available NFV Services
(Chapter, 2022)The ubiquitous deployment of middleboxes can hamper the network capability to be flexible, scalable and innovative to an extent that new and specialized services cannot be easily introduced in the network. Network Function ... -
Modeling and Simulation of a Waste Tire to Liquefied Synthetic Natural Gas (SNG) Plant
(Chapter, 2019)Thermochemical conversion of solid wastes through gasification offers the dual benefit of production of high-value fuels from the recovered energy and environmentally friendly waste disposal. Waste tires in particular may ... -
Modeling and Simulation of Bridge-Section Buffeting Response in Turbulent Flow
(Peer reviewed; Journal article, 2019)Buffeting analysis plays an important role in the wind-resistant design of long-span bridges. While computational methods have been widely used in the study of self-excited forces on bridge sections, there is very little ... -
Modeling and Simulation of Chemical Looping Combustion Using a Copper-Based Oxygen Carrier in a Double-Loop Circulating Fluidized Bed Reactor System
(Journal article; Peer reviewed, 2017)In this work, a computational fluid dynamics simulator has been developed for a novel double-loop circulating fluidized bed reactor which is used for a chemical looping combustion process. The simulator is implemented in ... -
Modeling and simulation of energy systems: A review
(Journal article; Peer reviewed, 2018)Energy is a key driver of the modern economy, therefore modeling and simulation of energy systems has received significant research attention. We review the major developments in this area and propose two ways to categorize ... -
Modeling and Simulation of Moored-Floating Structures Using the Tension Element Method
(Peer reviewed; Journal article, 2019)The derivation of a discrete mooring model for floating structures is presented in this paper. The method predicts the steady-state solution for the shape of an elastic cable and the tension forces under consideration of ... -
Modeling and simulation of oil-free liquid-injected screw compressors using ammonia-water mixture as working fluid
(Chapter, 2022)This study investigates the compression process of an oil-free screw compressor with liquid injection for an absorption-compression heat pump (ACHP) with an ammonia-water mixture as working fluid. In recent years, several ... -
Modeling and Simulation of the Accumulator During Active Heave Compensation Operations
