Hierarchy of Motor Control01:18

Hierarchy of Motor Control

4.1K
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.

Coordination Number and Geometry

17.0K
For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers to molecular geometry. The most common structures of the complexes in coordination compounds are octahedral, tetrahedral, and square planar.

Collisions in Multiple Dimensions: Problem Solving

4.6K
In multiple dimensions, the conservation of momentum applies in each direction independently. Hence, to solve collisions in multiple dimensions, we should write down the momentum conservation in each direction separately. To help understand collisions in multiple dimensions, consider an example.
A small car of mass 1,200 kg traveling east at 60 km/h collides at an intersection with a truck of mass 3,000 kg traveling due north at 40 km/h. The two vehicles are locked together. What is the...

Collisions in Multiple Dimensions: Introduction

5.8K
It is far more common for collisions to occur in two dimensions; that is, the initial velocity vectors are neither parallel nor antiparallel to each other. Let's see what complications arise from this. The first idea is that momentum is a vector. Like all vectors, it can be expressed as a sum of perpendicular components (usually, though not always, an x-component and a y-component, and a z-component if necessary). Thus, when the statement of conservation of momentum is written for a...

Sequence Networks of Rotating Machines01:24

Sequence Networks of Rotating Machines

175
A Y-connected synchronous generator, grounded through a neutral impedance, is designed to produce balanced internal phase voltages with only positive-sequence components. The generator's sequence networks include a source voltage that is exclusively in the positive-sequence network. The sequence components of line-to-ground voltages at the generator terminals illustrate this configuration.
Zero-sequence current induces a voltage drop across the generator's neutral impedance and other...

Indirect Motor Pathways01:22

Indirect Motor Pathways

1.9K
The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...

Area of Science:

  • Traffic Engineering
  • Intelligent Transportation Systems
  • Control Theory

Background:

  • Uncoordinated traffic flow in roundabouts causes congestion, delays, and increased fuel consumption.
  • Connected and automated vehicles (CAVs) offer potential for cooperative traffic management.
  • Traditional roundabout systems (TRS) lack efficiency in managing complex traffic scenarios.

Purpose of the Study:

  • To propose a novel Roundabout Control System (RCS) for CAVs.
  • To enhance traffic flow smoothness and safety in roundabouts.
  • To minimize vehicle entry time while preserving circulating traffic movement.

Main Methods:

  • A bi-level control framework: higher level clusters vehicles, lower level optimizes sequences and merging times.
  • Combinatorial optimization problem solved using a receding horizon control (RHC) approach.
  • Real-time implementation with fast optimization capabilities.

Main Results:

  • Microscopic simulations demonstrate the RCS's effectiveness compared to TRS.
  • Significant improvements observed in average velocity, fuel consumption, and travel time.
  • The system successfully minimizes total vehicle entry time.

Conclusions:

  • The proposed RCS offers a viable solution for efficient roundabout traffic management.
  • Cooperative control of CAVs through RCS leads to substantial performance gains.
  • RCS ensures safe and smooth traffic flow, reducing congestion and delays.
