Modeling of voltage source converter based HVDC transmission system in EMTP-RV
… in a power transmission system is the precise control of active and reactive power flow to maintain the system voltage stability. The VSC operating with the specified vector control strategy can perform independent control of active/reactive power at both ends. This ability of VSC makes it …

VOF Based Multiphase Lattice Boltzmann Method Using Explicit Kinematic Boundary Conditons at the Interface
… is developed. The advantage of the method is the direct control over the surface tension value. The details of the numerical method are presented. The Saffman instability, Taylor instability, and flow of deformable suspensions in a channel are used as example-problems to demonstrate the accuracy …

Teleoperation System for Autonomous Vehicles
… a) AV with a temporal delay through real-time direct control within the constraints of current wireless communication technology in an unpredictable road environment, and b) enhancing the AV's inherent detection capabilities to augment its autonomous control abilities, thereby reducing the …

INSTRUMENTATION AND CONTROL OF AN INDUSTRIAL SEWING MACHINE
… sewing machines must be capable of measuring and controlling their performance. The advancement of practical, automated, high speed sewing machines, which are capable of optimising sewn seam quality, will greatly benefit the garment industry. Research on sewing ability has led to a greater …

Regenerative electric actuators for active control of civil structures
… which supply energy to the actuator in an active control system is usually not reliable. With a regenerative electric actuator, recovered energy can be used to reduce the peak oscillations of the structure by applying forces (through actuators which use the recovered energy) counter to the …

Interactive control of linked rigid body simulations
… Simulation alone, however, prevents intuitive direction. In the worst case, an artist repeatedly tweaks a variety of simulation parameters until she achieves the desired effect. Because of the complexity of the dynamics of linked rigid bodies, the tweaking becomes tedious, even for the simplest …

Improvisational interaction : a framework for structural exploration of media
… interact with media, our experience is that of direct control, and the goal of our interactions is either artifact-production (the editor paradigm) or passive exploration (the browser paradigm). This thesis proposes an alternative: a model of media interaction based on the ideas of non-idiomatic …

Paleolimnology and paleoecology of the Coal Valley region, Lincoln County, Nevada
… of the lake. Coal Lake probably experienced more direct control by regional groundwater hydrology than by climate. The revised paleohydrologic index of Coal Valley is (Z{dollar}\sb{\rm cv}{dollar} = 0.11, compared to the previous value of 0.07, suggesting that the water balance of Coal Lake was …

Asset allocation and Regulation 28
… or constraints on pension funds under direct control of trustees. This study evaluates some of the constraints imposed on the Regulation 28 through the use of Markowitz (1952) efficient frontier framework and a non-parametric model. With offshore allocation increased to 25% and an …

Multi Agent Systems for the Active Management of Electrical Distribution Networks
… of customerowned SSEGs, energy storage units and controllable loads. This approach represents a move away from the conventional passive, “fit-and-forget” philosophy under which the majority of Low Voltage (LV) distribution networks are currently operated and towards a higher degree of network …

Pricing with Bivariate Unspanned Stochastic Volatility Models
… simplest case, comprising of one state variable controlling the term structure and the other controlling unspanned volatility. This dissertation focuses on pricing with two particular bivariate USV models: the Log-Affine Double Quadratic (1,1) – or LADQ(1,1) – model of Backwell (2017) and the …

Interactive Procedural Design Exploration for Modular Structures
… using stochastic systems does not give designers direct control over the generation process. By controlling the stochasticity of the generation process based on user feedback and performance goals, the methodology proposed in this thesis generates design options that follow specific design intent …

Model-following control applications to nonlinear mechanical systems
Model-following control design methodology is introduced for nonlinear plants and models. The plant equations are considered to be linear in the control input. Dynamic matching conditions are presented and the resulting error dynamics are given. The stability of error dynamics is ensured, using …

Some observations on the population dynamics of the Australian soldier fly Inopus Rubriceps Macquart (Diptera: Stratiomyidae)
… with the failure to find a suitable chemical control from several insecticidal screening trials (Hewitt 1964) precluded, at least initially, any worthwhile work on direct control methods. Clark et al (1967) have argued that in those cases where no prior hypotheses can be made about an insect, …

Transmit Signal Design for MIMO Radar and Massive MIMO Channel Estimation
… arrays and the capability to independently control signal emissions from each antenna make transmit signal design increasingly important for radar and wireless communication systems. In the rst part of this work, we develop the framework for a MIMO radar transmit scheme which trades o …

Regulatory options for cross-border gas supply security
… from production to consumption supports the control of gas supply realisation; (ii) the approach of collaborative exercise in legal engagement and performance responds to the condition of codependence and eases the affordability constraint of the consuming country in realising cross-border …

Process variables controlling consistency of carbon nanotube forest growth
… called CNT forests, are the precursor for controlled-morphology macroscopic nanocomposites and nanoengineered composites due to theirscale-dependent, tunable physicall properties. Applications include polymer and ceramic matrix nanocomposites (PNCs and CMNCs), nanostiching as laminate …

Planning and Scheduling in Temporally Uncertain Domains
… techniques for planning and scheduling is controllability of activities: the agent is assumed to be able to control the timing of starting and ending of each activity. In several practical applications, however, the actual timing of actions is not under direct control of the plan executor. …

The Future of Technology Bargaining in the Information Age
… entire production process is becoming easier to direct, control, and monitor. Each new task presents management a new lever of power in two forms -- the decision to substitute and the ability to monitor. While substitution of technology for labor remains an issue, the complementarity of labor and …
