Empirical Estimation of a Macroscopic Fundamental Diagram (MFD) for the City of Cape Town Freeway Network
… fundamental diagram (herein referred to as MFD) to characterize the state of an urban-scale network has thus far proven to be more effective than other approaches. MFD represents the state of urban traffic by defining the traffic throughput of an area at given traffic densities. It describes …

Establishment & Assessment of the Macroscopic Fundamental Diagrams for the City of Durban Freeway Network Using Empirical Data
… the context of Macroscopic Fundamental Diagrams (MFD) to date. The recent findings have shown that understanding the Macroscopic Fundamental Diagrams (MFD) in cities can bring success in managing congestions. This study aimed to establish the Macroscopic Fundamental Diagrams (MFD) for the City of …

Experimental investigation of energy dissipation behavior of the modified friction device
… The recently proposed modified friction device (MFD) addresses many of the concerns that have prevented the building industry from fully embracing non-passive control: the device is based on the drum brake, a reliable technology that is inexpensive, already mass manufactured, capable of producing …

Investigating the Properties and Existence of a Macroscopic Fundamental Diagram for Arterial and Freeway Traffic Systems
… revealed that a macroscopic fundamental diagram (MFD) linking space-mean flow , density and speed exists on a large urban area. Despite these and other recent findings for the existence of well defined MFDs for urban areas, these MFDs should not be universally expected. In this thesis, the …

Study of a Modified Friction Device for the control of civil structures
… device is studied: the Modified Friction Device (MFD). The MFD is a control device that consists of a spring, a viscous element and a braking element similar to car brakes. Because it is still a conceptual design, the device's frictional behavior has been modeled using the LuGre friction model …

Theoretical models of many-quark bound states
<p>The foundations of Many-Fermion Dynamics (MFD) are developed with special attention paid to a treatment of color and flavor degrees of freedom. From these ingredients a framework was developed to calculate the properties of many-fermion bound states. The quark implementation of MFD (MFDq) was …

Mitigation of wind induced movement of buildings using the modified friction device
… the design of a modified friction device (MFD) has been studied. Requiring only a small amount of energy, the MFD is a new kind of semi-active damper that provides stability, accurate control and effectiveness. Using a MATLAB program, it was possible to model a primary structure hit by a …

A Structural Perspective on Bacterial Transcription
… stall RNAP elongation complexes (ECs). The SF2 MFD translocase mediates TCR in bacteria by removing stalled RNAP from DNA lesions and recruiting appropriate TCR factors. Previously, we used cryoelectron microscopy to visualize MFD engaging with and attempting to displace the EC, revealing seven …

The effects of task and multifunction display characteristics on pilot viewport allocation strategy
"Multifunction displays (MFDs) and other electronic repositories of information are increasingly being deployed in the flightdeck environment. As is the case with the more traditional dedicated displays they are replacing, there is often a need to scan between information sources (i.e., screens) in …

Analysis of the effects of sire and age on wool quality traits in Romney ewes
… date significantly affected mean fibre diameter (MFD), mean curvature, coarse edge (% fleece 10µ > x̄) and the proportion of ewes with wool medullation (p=<0.001). Average changes in wool traits between hoggets and two tooths were as follows. MFD increased 5.5 micron (hogget x̄=31.9, two tooth …

Regulation of milk fat synthesis by dietary fatty acids
… in lactating cows fed milk fat depressing (MFD) diets. This analysis showed that in addition to the established inhibitory effect of t10c12 CLA, t7-18:1 and t7c9-CLA isomers might be involved in MFD. Lactating mice were used to test the effects of several individual trans-18:1 isomers and …

Efficient modeling and waveform inversion of multicomponent seismic data for anisotropic media
… propagators using mimetic finite-difference (MFD) operators and fully staggered grids (FSGs). Also, I present an EFWI framework based on these propagators and discuss inversion strategies for estimating the parameters of coupled fluid/solid VTI (transversely isotropic with a vertical symmetry …

HIGH EFFICIENCY EDGE COUPLER, NOVEL NONLINEAR OPTICAL POLYMERS WITH LARGE KERR-COEFFICIENT AND AUTOMATIC LAYOUT GENERATION IN SILICON PHOTONICS
… for flat fibers with larger mode-field-diameter (MFD), a novel sub-wavelength grating based edge coupler is proposed and experimentally demonstrated to have 1.9dB/facet loss. Eventually a silicon multi-section taper with intermediate SU-8 waveguide cladding is proposed for flat fibers with even …

Understanding Traffic Congestion Through Multiscale Analysis: Sensor Deployment, Car-Following and Universal Scaling
… such as the macroscopic fundamental diagram (MFD), are widely used to capture the relationship between average flow and density across urban networks. While loop detector data is the most commonly used source for estimating the MFD, its accuracy can be affected by how detectors are positioned …

Approximating three-dimensional fluid flow in a microfluidic device with a two-dimensional, depth-averaged lattice Boltzmann method
Microfluidic devices (MFDs) are important tools in the study of reactive transport processes in porous media. Laboratory and numerical experiments have studied reactions such as bimolecular complexation, biodegradation and biofilm growth, and mineral precipitation coupled to fluid flow in MFDs that …

Flood Risk Analysis on Terrains
… direction (SFD) and multiflow-directions (MFD) models, in which water at a point flows along a single downslope edge or multiple downslope edges respectively. Algorithms are given for the more specific case of the SFD model, and then it is shown how to answer queries in the more general …

Optimisation of condition number for eigenstructure problems
… decomposition using matrix fraction description (MFD) has been derived. Within this thesis the construction and the existence of controllability subspaces connected to (A,B)-invariant subspaces, has also been studied. In addition, an algebraic description of the total system behaviour which leads …
