Design Example: Traverse Angle Computations

348
Traverse angle computations are a critical component of surveying, used to compute the internal angles within a closed traverse. A traverse consists of a series of connected lines forming a closed loop, often used for land boundary delineation or mapping. Calculating the internal angles ensures accuracy in the traverse geometry and is essential for checking survey data integrity.The process begins with known azimuths and bearings of the traverse sides. Internal angles at each vertex are...

Cooperative Allosteric Transitions01:58

Cooperative Allosteric Transitions

8.9K
Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand binds to any of these subunits, it triggers a conformational change that affects the binding sites in the other subunits; this can change the affinity of the other sites for their respective ligands. The ability of the protein to change the shape of its binding site is attributed to the presence of a mix of flexible and stable segments in the...

Cooperative Binding of Transcription Regulators

7.4K
Transcriptional regulators bind to specific cis-regulatory sequences in the DNA to regulate gene transcription. These cis-regulatory sequences are very short, usually less than ten nucleotide pairs in length. The short length means that there is a high probability of the exact same sequence randomly occurring throughout the genome.  Since regulators can also bind to groups of similar sequences, this further increases the chances of random binding. Transcriptional regulators form...

First Law: Particles in One-dimensional Equilibrium

8.3K
Newton's first law of motion states that a body at rest remains at rest, or if in motion, remains in motion at constant velocity, unless acted on by a net external force. It also states that there must be a cause for any change in velocity (a change in either magnitude or direction) to occur. This cause is a net external force. For example, consider what happens to an object sliding along a rough horizontal surface. The object quickly grinds to a halt, due to the net force of friction. If...

First Law: Particles in Two-dimensional Equilibrium

16.9K
Recall that a particle in equilibrium is one for which the external forces are balanced. Static equilibrium involves objects at rest, and dynamic equilibrium involves objects in motion without acceleration; but it is important to remember that these conditions are relative. For instance, an object may be at rest when viewed from one frame of reference, but that same object would appear to be in motion when viewed by someone moving at a constant velocity.
Newton's first law tells us about...

Background:

  • Cooperative guidance for multiple missiles is crucial for modern defense systems.
  • Achieving simultaneous engagement with precise impact angles presents significant control challenges.

Purpose of the Study:

  • To develop a novel cooperative guidance law for simultaneous multi-missile engagement.

Main Methods:

  • Design of normal accelerations to control flight-path and heading angles for desired line-of-sight (LOS) guidance.
  • Construction of a consensus variable using available information.
  • Design of tangential acceleration to achieve consensus and control velocity magnitude.

Main Results:

  • The proposed guidance law enables multiple missiles to fly along the desired LOS.
  • Consensus is reached, ensuring simultaneous velocity adjustments for all missiles.
  • Simulations verify the effectiveness of the cooperative guidance scheme for hit-to-kill interception at desired angles.

Conclusions:

  • The novel cooperative guidance law effectively achieves simultaneous hit-to-kill attacks by multiple missiles.
