United States: What are the specific guidelines for driving from one state to another during this pandemic?

Stay home if your trip is not essential.

That said, traveling is still It is not prohibited in the United States.

Most service stations are open, as they are an essential service.

Upon arrival at your destination, stay in quarantine for at least 14 days, whether you have symptoms or not.

Some states have guidelines regarding travel, for example, Maine requests a quarantine 14 …

design: repeating a state on a state machine

I have a state machine where I might have to restart something when necessary (for example, restart a hardware). But after rebooting, I need to run some tests on it. If the tests fail, I need to stop the thing and exit the state machine with a failed state.

In case of failure, how should I handle the second stop of the thing? The state machine diagram loses its readability if I do it as follows. And the implementation gets ugly since I need to decide Stop thing state exit based on the previous state

Option 1

My other option is to create a second instance of the Stop thing Status as follows. But then it makes the state machine bigger

Option 2

Which of these is the correct approach? Or is there another way to tackle these kinds of problems?

If it matters here, I am using ROS Y smach for the implementation of the state machine

mathematical optimization: fitting experimental data to the SRK equation of state. Minimization

I am trying to find parameters to adjust an EoS to saturation pressures at different temperatures.

My experimental data is like this


Then I defined a function to calculate saturation pressures

psat(T_, p0_, Tc_, a0_, b_, c1_, E11r_, v11_) := (Do(
   p(0) = p0;
   f11 = Exp(-E11r/T) - 1;
   m11 = v11*f11;
   a = a0*(1 + c1*(1 - Sqrt(T/Tc)))^2;
   (Alpha) = p(i)*a/(R*T)^2; (* Dimensionless groups*)
   (Beta) = p(i)*b/R/T;
   (Gamma) = p(i)*m11/R/T;
   d0 = -(Gamma)*(Beta)*((Beta) + (Alpha));(*Coefficients of the equation*)
   d1 = (Alpha)*((Gamma) - (Beta)) - (Beta)*(Gamma)*(1 + (Beta));
   d2 = (Alpha) - (Beta)*(1 + (Beta));
   d3 = (Gamma) - 1;
   d4 = 1;
   polin = d4*z^4 + d3*z^3 + d2*z^2 + d1*z + d0;
   Raices = NSolve(polin == 0, z, PositiveReals); (* Solving the 4th grade polinomy for compressibility factor*)
   zv = Max(z /. Raices);
   zl = Min(z /. Raices);
   vv = zv*R*T/p(i);
   vl = zl*R*T/p(i);
   ln(CapitalPhi)v = 
    zv - 1 - Log(zv) + Log(vv/(vv - b)) + a/b/R/T*Log(vv/(vv + b)) + 
     Log(vv/(vv + m11)); (*Fugacity coefficients*)
   ln(CapitalPhi)l = 
    zl - 1 - Log(zl) + Log(vl/(vl - b)) + a/b/R/T*Log(vl/(vl + b)) + 
     Log(vl/(vl + m11));
   (CapitalPhi)v = Exp(ln(CapitalPhi)v);
   (CapitalPhi)l = Exp(ln(CapitalPhi)l);
   p(i + 1) = p(i)*(CapitalPhi)l/(CapitalPhi)v,
   {i, 0, 9});

Where T is the temperature p0 is the initial pressure assumption, Tc is the critical temperature and a0, b, c1, E11r, v11 are the parameters of the equation.

Up to this point, we have a saturation pressure calculator, given the parameters, and it works fine, now what I can't seem to solve is fitting it to my experimental data, minimizing an objective function, which is:

enter the image description here

I said it like this:

F(a0_, b_, c1_, E11r_, v11_) := 
 Sum((psat(psatx((k, 1)), psatx((k, 2)), Tcaceto, a0, b, c1, E11r, 
      v11) - psatx((k, 2)))^2/psatx((k, 3))^2, {k, 200});
(* I declared the Tc as "Tcaceto", a constant, and I use as initial guess for each psat calculation the experimental pressure*)

And then I just used NMinimize, In this way.

NMinimize(F(a0, b, c1, E11r, v11), {a0, b, c1, E11r, v11})

I run it, and it never ends. I don't know what might not be working, I have tried to configure the method, the starting points, but the result is the same. I would really appreciate someone to help me on this matter. Thank you.

Computer Architecture: Should a Solid State Hard Drive Make Crisp Working Noises?

I use heavy software. 3d, mostly. I am used to the comforting sound of a hard drive that sounds like a popcorn.

But I just got my first Lenovo, with a solid state hard drive. Model KXG6AZNV512G TOSHIBA
to be exact.

It is making high-frequency noises … even in sequence with every key press (Firefox browser, memory usage 1104).


When I use zbrush I hear hums with each rotation of the model.

This is normal?

United States: Why is New Jersey (the US state) so associated with a kind of "low-profile worker" stereotype?

I do not live in New Jersey, nor have I been there.

I have heard on numerous occasions, often from "New Jerseyians" themselves, sarcastic jokes and comments related to people (or men specifically, generally) from New Jersey who are very "humble" or "uneducated", for example, allegedly They speak in a way that sounds "stupid" or "comical," and supposedly they don't care much about anything or anyone outside of New Jersey. Of course, this does not apply to each individual, but apparently to "a large percentage".

In this stereotype, it seems that the guy is often Italian-American. However, I have further I heard a different stereotype about New Jersey, where apparently an unusual number of Jews live there, and in which this is the distinctive "feature" of New Jersey. But I've also heard that about Long Island (which is not a state but part of New York) and New York (the state, in general), so I don't know what to do with it.

I suppose it is possible that both are true.

What I wonder is why New Jersey specifically was "chosen" by this (first) stereotype. That is, among the "northern" states. I never heard anyone make fun of any other northern state in this way. There must be something I'm missing about New Jersey history.

I hope my question is clear enough and does not offend anyone. Again, I am trying to understand why this stereotype exists; I have no particular dislike / hatred for New Jersey or the people who live there.

Why did Cuomo allow sick New Yorkers to leave the state to infect the United States?

What do you want me to do, arrest anyone (healthy or not) who wants to leave the state and put them in prison to prevent them from escaping, or shoot them at the state border if they want to leave? If you want to live in a police state, go immigrate to Russia, Venezuela or China. What about Covidfe? Why not arrest him because he does not require a national travel ban?

dnd 5e: do the rules state that a top-tier character cannot have a skill score higher than 18?

Basic Rules / PHB Chapter 1, titled "Step-by-Step Characters," lists how to determine skill scores in Step 3 (emphasis added):

You generate all six of your character skill scores Randomly roll four 6-sided dice and record the total of the three highest dice on a piece of scrap paper. Do this five more times, so you have six numbers. If you want to save time or don't like the idea of ​​randomly determining skill scores, you can use the following scores: 15, 14, 13, 12, 10, 8.

Now take your six numbers and write each number next to one of your character's six abilities to assign scores to Strength, Dexterity, Constitution, Intelligence, Wisdom and Charisma. Then make any changes to your skill scores as a result of your race choice.

Using the "4d6, drop the lowest" method of skill score generation, the only limit on what you can roll is what the dice literally limit you to: a maximum of 18 (unlikely but possible, if you roll at least three 6s), and a minimum of 3 (very unlikely – only possible if you roll four 1s).

However, these numbers are the basic statistics, before racial modifiers are applied. So if you roll at least 18 and choose a career that gives +1 or +2 to a skill score, you can start with a score of 20 on that skill.

(The point purchase variant for generating skill scores has stricter minimums and maximums on the skill scores you can have, but you're not using that method, so I won't go into detail.)

The DM can add house rules, but they must make it clear when they do.

D&D empowers the DM to run their game as they see fit, and add house rules if they so choose. However in his case it seems the DM seems to think that there is an official rule that prevents characters from starting with a skill score of 19 or 20 after adding racial mods. There is no such rule.

I would recommend asking your DM to review the character creation rules with you, and politely ask them to point to the rule they think says you can't start with a skill score of 18 or higher. Otherwise, if it's a house rule, you should ask your DM for clarification. Then you can decide whether you are willing to accept that house rule or not.

drive: using a state pattern in multiple controllers / general architecture tips

I'm trying to implement a state pattern, having skated through enumerations forever, and have run into a wall when it comes to its implementation in my game. It is a grid based strategy game with an MVC hierarchy.

The general flow is InputManager -> CursorManager -> GridManager. So if the player presses "Up" the InputManager will translate it to the appropriate action and notify the CursorManager. The CursorManager will update the world position of the cursor and then ask the GridManager to find what is in the hex to update the UI with terrain / unit information.

So my new addition is to have the GridManager change the cursor state depending on what is in the tile. Did you push yourself? Let the cursor state dictate what happens to the grid. So naturally I created a cursor state object in the CursorManager, but suddenly I realized that each state needed a decent amount of information shared between different controllers.

For example,

public class FreeCursor : CursorState
    public override void ActionPressed()
        currState = gridManager.selectTile(cursor.position); 

This means that the FreeCursor state would need a reference to the GridManager object, a reference to the GameObject cursor, and also a reference to the current state. All 3 are already in the CursorManager, so no problem, just put them in a constructor: FreeCursor(CursorState context, GridManager gridManager, GameObject goCursor)

But oh, when gridManager.tileSelected() complete, you must return the new state. So the GridManager should say

public CursorState selectTile(Vector3 position) { 
     return new FreeCursor(this);

… except that now we are missing the GameObject and the current state of the cursor, which are not accessible in the GridManager.

So it could go one or two ways: make the GridManager also contain a context reference, so it becomes return new SelectedUnitState(this, CursorManager) and change our flow to be InputManager -> CursorManager <--> GridManager. Or you could say screw it in, launch the cursor state and GameObject in the GridManager and call it day.

… but do you both feel bad? The last one combines two somewhat different controllers: the first one when passing the state, is an object that it contains as the reflection of a poor person or something like that. Because if I do that, I could also use Unity & # 39; s GameObject.Find(Cursor). Am I wrong to think this? And if so, is it the problem with my implementation of the state pattern or the way I've presented my & # 39; architecture & # 39 ;?

tl; dr: How do you handle a state pattern with data from multiple controllers?

Thank you!

Android RadioButton: drawableEnd does not change when state is changed

Was it appropriate for this African American state police officer to do this? SERIOUS ANSWERS?

Our state is under orders to stay home.

Our children as children did not pay attention or probably did not recognize the seriousness of the situation.

Anyway, they left home to go play basketball with friends in a nearby park.

I suppose an African American state patrol car patrolling people in violation of not quarantining them saw them play.

From what I heard from my son was that he drove up to the kids and told them

"You all need to get home. If I see you little niggas here again, you won't come home, you will go to jail with me. Now dive in."

Updated 2 hours ago:

Can I file a civil complaint? He should have called us and we would have picked them up. now they distrust public service officials.
