Real-time power system topology change detection and identification
… and identification of system topological changes in near real-time that utilizes the statistical properties of electricity generation and demand, which are assumed to be known. Instead of relying on offline models as with traditional methods, the proposed method is model-free, and exploits …

Cell Topology Change by the Physical Engagement of Neighboring Cytoskeletal Networks
Cell topology changes are often associated with neighboring zones of distinct actin cytoskeletal networks and regulators, such as lamellipodium and lamella in migratory cells, branched and unbranched actin networks at cell-cell contacts, and concentric rings of Rho family GTPases during wound …

Fast power network detection of topology change locations using PMU measurements
… for the purpose of on-line analysis. Several topology processing schemes have been developed in the literature to accomplish this task. The majority of these schemes process breaker statuses to detect changes in system topology. Transformer tap positions as well as statuses of capacitor and …

A Numerical Scheme for Mullins-Sekerka Flow in Three Space Dimensions
… overcoming node bunching, and dealing with topology change in a toroidal particle. A particle (node)-cluster technique is developed with the aim of alleviating excessive run time caused by filling the dense matrix used in solving a system of linear equations.</p>

Development and application of a new voltage stability index for on-line monitoring and shedding
… weakest system buses. Furthermore, a method for topology change detection suitable for online systems was proposed. Dynamic stability monitoring with PMU measurements was simulated in real-time on the well-known Kundur 10-bus system and the appropriate load shedding using the P-index was …

Efficient channel allocation and medium access organization algorithms for vehicular networking
… In order to make this method efficient in rapid topology change environment like VANET, it's important to make the network topology less dynamic by forming local strongly connected clustering structure, which leads to a stable network topology on the global scale. We propose an efficient cluster …

Development and validation of coaxial cable sensors for damage detection of reinforced concrete structures
… directly but, more significantly, to the topology change in the outer conductor associated with the cable elongation. The latter effect is first proposed and investigated in this study.</p> <p>An analytical model of the proposed sensor design was developed in this study to establish the …

Rotational Symmetry and Phase Dynamics in Topological Superconductors
… corners, indicative of so-called second-order topology. We establish a bulk-boundary correspondence linking the presence of such Majorana bound states to bulk topological invariants based on momentum-space rotation representations. We thus establish when a topological crystalline superconductor …

Physics on Noncommutative Spacetimes
… <p>The fuzzy Higg's manifold is found to exhibit topology change, an important property for any theory attempting to quantize gravity. We study how this change occurs in the classical setting and how quantizing this manifold smoothens the classical conical singularity. We also show the …

A moving mesh method for non-isothermal multiphase flows
… Secondly, a numerical treatment of interface topology changes is incorporated into our method for studying problems with interface breakup. Thanks to the adaptive mesh generator, the thin region between the interface boundary and another boundary consists of one layer of elements. The …

Analysis of the flow structure and reattachment over accelerating non-slender delta-wing planforms
… edge to trailing edge can be indicated by the topology change of nFTLE ridges. This reveals a direct connection of the kinematics (FTLE scalar field) to the aerodynamic performance (surface pressure). The high pressure is followed by a strong leading edge suction, which further confirms the …

FORMATION, REFINEMENT, AND REORGANISATION OF COMPLEX BRAIN NETWORK TOPOLOGY ACROSS THE LIFESPAN
… the organisation of these connections form and changes across the lifespan. In Chapter 1, I provide theoretical background about the study of complex systems and the common properties observed across them – small-worldness, scale-free degree distributions and modularity. Diving deeper in brain …

Design, Implementation and Analysis of Wireless Ad Hoc Messenger
… A mobility configuration file thus defines topology changes at runtime and is used by all nodes to know whether they can communicate with others in a single-hop or multi-hops during an experimental run. We use five standard metrics to test the performance of the wireless ad hoc messenger …
