Multimachine Stability01:25

Multimachine Stability

623
Multimachine stability analysis is crucial for understanding the dynamics and stability of power systems with multiple synchronous machines. The objective is to solve the swing equations for a network of M machines connected to an N-bus power system.
In analyzing the system, the nodal equations represent the relationship between bus voltages, machine voltages, and machine currents. The nodal equation is given by:

Stability of structures

600
In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...

Stability

475
The time response of a linear time-invariant (LTI) system can be divided into transient and steady-state responses. The transient response represents the system's initial reaction to a change in input and diminishes to zero over time. In contrast, the steady-state response is the behavior that persists after the transient effects have faded.
The stability of an LTI system is determined by the roots of its characteristic equation, known as poles. A system is stable if it produces a bounded...

Microtubule Instability

6.4K
Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated...

Survival Tree

496
Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Area of Science:

  • Computer Science
  • Networking

Background:

  • Tree-based overlay multicast is crucial for media streaming but suffers from instability due to member departures, leading to performance degradation.
  • Existing solutions struggle to address the inherent instability of overlay multicast trees.

Purpose of the Study:

  • To propose VMCast, a novel solution to enhance the stability of tree-based overlay multicast.
  • To improve data distribution reliability in media streaming applications.

Main Methods:

  • VMCast utilizes two types of on-demand cloud virtual machines (VMs): multicast VMs (MVMs) for data dissemination and compensation VMs (CVMs) for streaming compensation.
  • VMs within a cloud datacenter form a VM cluster, responsible for a service domain (VMSD).
  • Data is reliably delivered to MVMs and disseminated to group members via domain overlay multicast trees, with CVMs providing compensation.

Main Results:

  • VMCast structurally improves the stability of the overlay multicast tree.
  • CVM-based streaming compensation further enhances data distribution stability within VMSDs.
  • Application of VMCast to HMTP and HCcast demonstrated significant enhancement in data distribution stability.

Conclusions:

  • VMCast offers a robust solution for enhancing tree-based overlay multicast stability.
  • The proposed system effectively mitigates performance issues caused by member departures in media streaming.
  • VMCast can be integrated with existing solutions to improve media streaming services.
