kandi X-RAY | flightpath Summary
Flightpath has been deprecated since the release of Ingress Gateway in Consul v1.8.0. This repository is now in read only mode and will not accept community contributions. Flightpath is an Envoy Control Plane that integrates with Consul Connect and provides L7 routing at edge. The need for Flightpath emerged from desperately wanting to deploy Consul Connect to production and frustration of not being able to route public traffic to a connect enabled service.

QUESTION
I looked up iterative Graph DFS and it showed using a stack for the edges but this is producing a different order vs recursive DFS. I tried using a queue for the iterative DFS as well but the only way I could get the same order as recursive DFS was using a stack of Map iterators come back to and resume the iteration over edges, but I feel like there is probably a better way to do it.
I've included each DFS method, recursive, iterative stack, iterative queue, and iterative Map iterators with the order of each being logged:
...ANSWER
Answered 2021-May-30 at 23:12Your stack of map iterators has the same result order as the recursive version because it accurately represents the state of the for
loop in the recursive function.
To contrast your simple stack version, look at the order in which edges are processed after all of them have been pushed onto to the stack: the next iteration takes the top one, which was pushed last; then the second-to-last and so on, essentially processing the edges in reverse order.
If you want to reproduce the same result as the recursive version, you have to stack the neighbors of each node in reverse. Also you'll want to skip processing them again if they have been visited in the meantime (i.e. if they had been put on the stack multiple times).
QUESTION
The broken method: hasPathDFSBroken
Working version: hasPathDFS
The working version has a contrived param added to make it work which I'd rather avoid.
I'm trying to understand why in the broken version when the call stack starts unwinding at LIM as currNode and it gets back to MEX as the currentNode, why does it not resume the unfinished for loop over MEX's neighbors?
Any help would be greatly appreciated. Thanks!
...ANSWER
Answered 2021-May-24 at 23:17why doesn't the unfinished for loop resume over MEX's neighbors?
Because the return
statement you have inside the loop immediately breaks from the loop and the function.
Instead, you need to look at the return value and continue with the loop if the recursive call hasn't found the destination:
QUESTION
Hi all I am working on rocket trajectory optimization with Dymos. The equations of motion for my model are for a spherical non-rotating Earth
where v is speed of the rocket, gamma is the flightpath angle to local horizontal, h is height above surface, theta is angle along the great circle of the trajectory, m is mass, epsilon is angle of attack, T is trust, D is drag, L is lift. These are quite similar to the equations of motion in the Dymos water rocket example. I used check_partials and my analytic derivatives seem to be correct.
As you can see gamma's rate of change is divided by v, so you have a singularity where v=0 at the beginning of the trajectory. You can get around that by starting v at some small number that's a small fraction of the intended final velocity -- like 1 to m/s for an orbital rocket.
However, the lower I set my initial velocity, the harder I can see the optimizer and grid refinement needs to work to get to a converged solution. For example,
setting final conditions of h=200 km, v= 7668 m/s and gamma=0 (a circular orbit), with v initial = 10 m/s, I have to start with 20 segments of order 6 to be able to reach convergence, and the final grid is like this
Number of Segments = 25 Segment Ends = [-1.0, -0.9833, -0.9667, -0.95, -0.9333, -0.9, -0.85, -0.8, -0.7, -0.6, -0.5, -0.4, -0.3, -0.2, -0.1, 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0] Segment Order = [9, 9, 9, 9, 9, 9, 9, 9, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6]
The optimization time on this converged grid is 45 seconds
if I use v_initial = 1000 m/s, same final conditions, and a starting grid of 20 segments of order 3, the final grid is
Segment Ends = [-1.0, -0.95, -0.9, -0.8, -0.7, -0.6, -0.4, -0.2, 0.0, 0.2, 0.4, 0.6, 0.8, 1.0] Segment Order = [6, 6, 6, 6, 6, 3, 3, 3, 3, 3, 3, 3, 3]
the optimization time on the converged grid is 3.18 seconds.
Given the way grid points are being concentrated towards the beginning of the trajectory makes me think that the singularity in gamma_dot caused by v is the problem.
What can I do to improve performance?
...ANSWER
Answered 2020-Dec-11 at 10:08I agree that the singularity here is a problem, and your approach of setting it to some small initial value is generally a good way to go.
While they're generally pretty reasonable, the grid refinement algorithms currently in Dymos might have issues when the EOM start going singular, and I think you're seeing that here.
What else can you try?
-You could break the problem into multiple phases. The first phase would cover the vertical ascent before pitchover begins. By using a set of EOM that are non-singular for this phase of the trajectory, you could allow the vehicle to build up some speed before transitioning to the second phase, using your current EOM.
-You could reformulate the problem to use EOM that don't have a singularity near your operating conditions. Flight path EOM are generally nice and benign, but they suffer from singularities at v=0 (and gamma=+/-90 deg in the 3D case).
A Cartesian formulation to the EOM, where the vehicle inertial position and velocity are [x, y, vx, vy], would provide EOM that are only singular at the center of the planet. Parameterizing the initial states is somewhat more tricky (especially in the 3D case) because the initial velocity is the initial velocity of the launch pad fixed to the rotating Earth.
You could also try treating flight path angle as a fixed parameter for the first phase, fixing it to 90 degrees until some adequate velocity is established. In this case you'd be accepting some small inaccuracy in your dynamics in order to get better behavior.
QUESTION
My Scenario. I have five markers and connecting to the polyline. When I click marker a to marker b between polyline it will show an info window. In the info, the window has marker a address and marker b address. I achieved this scenario using islocationedge concept in google Maps API. but this concept I facing an issue. when I click marker a to marker b polyline it will show marker b and marker c address because segment polyline I used. I need how to assign an info window in an individual polyline.

...ANSWER
Answered 2020-Oct-28 at 02:47The tolerance in your call to isLocationOnEdge
is too small.
isLocationOnEdge isLocationOnEdge(point, poly[, tolerance])
Parameters:
point: LatLng
poly: Polygon|Polyline
tolerance: number optional
Return Value:* boolean
Computes whether the given point lies on or near to a polyline, or the edge of a polygon, within a specified tolerance. Returns true when the difference between the latitude and longitude of the supplied point, and the closest point on the edge, is less than the tolerance. The tolerance defaults to 10-9 degrees.

I am creating an ASP.NET MVC application where I display a google map with coordinates from a database. I am a rookie at this and I have got stuck on an issue with nested foreach loops... On the C# Razor page I have a JavaScript function "Initialize" in which I loop through an array of objects containing the coordinates and create a polyline based on them and then add it to the map. This works fine and the code looks like this:

Answered 2020-Jul-06 at 05:49Simplest way:
- include the google maps geometry library.
- use the poly namespace
isLocationOnEdge
method to detect which segment of the polyline the click was on. Output the two end coordinates of that segment.
isLocationOnEdge(point, poly[, tolerance])
Parameters:
point: LatLng
poly: Polygon|Polyline
tolerance: number optional
Return Value: boolean
Computes whether the given point lies on or near to a polyline, or the edge of a polygon, within a specified tolerance. Returns true when the difference between the latitude and longitude of the supplied point, and the closest point on the edge, is less than the tolerance. The tolerance defaults to 10-9 degrees.

I'm trying to do some basic animation with Gsap 3 TweenLite and bezier but all I get is:
Invalid property Bezier set to {curviness: 2, autoRotate: true, values: Array(1)} Missing plugin? gsap.registerPlugin()
and here's my code:
...ANSWER
Answered 2020-Feb-10 at 12:29There are a few problems:
- You're loading GSAP 3 (good!) which has been modernized quite a bit. Most code is totally backward compatible but BezierPlugin is an exception, as explained in the migration guide: https://greensock.com/3-migration#motion-path - you should use MotionPathPlugin now. It's way more capable and easy to use.
- You mistyped it as "Bezier" (it shouldn't be capitalized), but again, bezier isn't valid in GSAP 3. Use MotionPathPlugin.
- You only have one point in your "values" Array. Why?
- You're using the old syntax which is okay, but I'd strongly recommend updating to the shorter, more intuitive GSAP 3 syntax. It's all simplified into a single "gsap" object (no more TweenLite, TweenMax, TimelineLite, and TimelineMax). Your code could be made quite a bit shorter. The eases are now string-based too (shorter). I think you'll really like the new syntax.
It could look something like:

I'm creating a little demo page that displays some straight forward functionality of UI5. This page consists of two main pages:
- On the first page, there's a list of carriers which can be created, deleted, and updated. These carriers have an ID (
Carrid
). - If one clicks a carrier, they get routed to the second page on which all the flights of the selected carrier are shown in a table (with some information about the flights).
The table looks like this:
...ANSWER
Answered 2019-Dec-05 at 12:18There is no need for "hacky approaches" or custom formatters in case you simply want to display the time (or date) in a human readable form. UI5 comes with the concept data typesdoc which has the following advantages:
- Let UI5 format, parse, and even validate the value for you.
- Supports two-way data binding in contrast to
formatter
. - Additional format options or input constraints can be defined.
In our case, the appropriate type
for displaying the value of Edm.Time is sap.ui.model.odata.type.Time

QUESTION
Given two vectors which intersect at a point in 3D space, I would like to determine (and display) the plane which bisects these lines.
So far I have done the following:
0) Plotted the vectors (red)
1) Computed the cross-product (blue) and the dot product angle between the two vectors.
2) Rotated one of the vector by the 1/2 the angle between them, using the cross-product vector as the axis of rotation. The result is normal to the plane (green).
3) Using the normal, solve for 'd' in the ax+by+c*z+d = 0 equation of the plane.
4) Plot the resultant plane.
...ANSWER
Answered 2019-Oct-25 at 18:18In this special case, the normal vector for the new plane is just the concatenation of the two vectors. I would go like this:
- given three points
p1,p2,p3
computea1 = unit(p2-p1)
,a2=unit(p3-p2)
- compute the normal vector of the plane as
n = (a2+a1)
- construct the plane passing
p2
with normaln
