I’m using Altium designer 17 and I want to make a 3D layout of my board.
My only problem is that whenever I place a piece on the pcb, the component is flashing green and it says Collision. It Collision even if nothing is touching the pcb. Exemple this transfo:enter image description here

It sounds like your vertical component clearance is set to infinite, or at least a ridiculous number. I generally set mine to 0mm unless a specific application requires that I change it. You can modify this value in the Design -> Rules window (shortcut D-R), down near the bottom under «Placement». Look for «Component Clearance» and set the «Minimum Vertical Clearance» to 0mm. If the radio button to the left is set to «Infinite» you’ll have to change it to «Specified» before adjusting the number. See if that helps.

Right Click on Component’s Footprint > Component Action > Manage 3D Bodies
Under Column: Body State Click on «In Component X» (where X is the name of the component), it will change to «Not in Component X».

What it does is that it disables the invisible 3D boundary around the component so that you can place a custom 3D boundary.

When I tried to connect a trace to a pad on the bottom layer in the Altium project, I get the following error message:

Clearance constraint between track on bottom layer and polyregion on multilayer`

enter image description here

Any idea on resolving this? Do I have to create a stack up to the board or change some layer setting?

By referring to this altium page, the error creeped in because the layer stack was not properly defined.

So, in the Board Region dialog on the Altium UI we have to assign the stack up to the board region.

When working with RF Designs Collisions are a way of life.























What we have here is two parts on three pads. Actually it’s two parts with overlapping pads.


Only one of the two overlapping parts will be installed at any given time.


This technique is used to minimize parasitic traces and pads (no RF stubs).  


Using this technique you can create controlled impedance routes with minimum impedance discontinuities.


To get through the Design Rule Checks (DRCs) we can either disable the check or create an exception in the rules for the overlapping parts.


I recommend solution number 2 shown below..

Solutions:


1) Disabling Component Clearance Checks (not recommended).

2) Creating a rule with exceptions for the overlapping parts. (recommended).

Syntax:


InComponent(‘C307’) 

Parent page: MultiBoardAssembly Commands

The following pre-packaged resource, derived from this base command, is available:

Applied Parameters: None

Summary

This feature is used to check for collisions between the various constituent entities of the multi-board assembly. Collision checking is performed between each PCB and the top and bottom enclosures/cases, as well as between the PCBs themselves.

Access

This command can be accessed from the Multi-board Assembly Editor by:

  • Choosing the Tools » Check Collisions command from the main menus.
  • Using the Ctrl+K keyboard shortcut.

Use

After launching the command, the software checks for collisions between the various entities involved in the multi-board assembly. First, each board is checked for collision with the upper and lower enclosure/case parts (STEP parts), followed by checking between the boards themselves (PCBs). Any collisions will be reported through the Messages panel, and the offending objects highlighted using the Violation system color.

Use the Details region of the Messages panel to investigate which component on a board involved in a conflict is causing the collision.

Tips

  1. Collision checking will be carried out between all boards and the enclosure/case parts, regardless of a board’s/part’s visibility in the workspace.
  2. The Violation color can be defined on the Multi-board Assembly — View Configuration page of the Preferences dialog. It can also be changed on-the-fly from the View Configuration panel.

soy nuevo en este foro y tambien en este mundillo de la programacion, soy novato llevo 3 semanas aprendiendo python, y estoy tratando de crear un pequeño programa: se trata de una pizzeria, el usuario ingresa por pantalla un monto de dinero y el programa basicamente toma los pedidos del usuario, una pizza de peperoni por ejemplo y los añade a una lista, seguido se le da la opcion al usuario para que escoja un complemento si lo desea, y es aqui donde esta mi problema, en el programa muestro por panatalla el valor del producto y el restante (ej: si la pizza cuesta 7 euros ese valor se resta al monto que el usuario ingreso por pantalla) todo va bien hasta que doy la opcion de escoger ingredientes ( estos tienen el valor en centimos) al restar lo que cuesta añadir ese ingrediente lo hace mal y me da un resultado erroneo y ese fallo se ve reflejado al final cuando muestro el cambio que recibio el cliente, perdonden si no me supe explicar muy bien pero les adjunto el codigo:

Code:

# definiendo variables:
dinero = float(input('introduce el monto a  utilizar: n € '))
MONTO_INICIAL = dinero

#pizzas
peperoni = 5.60
hawayana = 7.00
quesos = 7.50
#ingredientes
queso_chedar = 0.50
pollo = 0.50
champiñones = 0.80
# Restante
total = 0
ticket  =  []
# titulo
print('BIENVENIDO A 'JORGE'S PIZZA')
print('--------------------------------')    

#menu
while True:
    print(f'1. pizza mediana peperoni: € {peperoni} ')
    print(f'pizza mediana hawayana: € {hawayana}')
    print(f'pizza  mediana 4 quesos: € {quesos}')

    pregunta = int(input('elija la pizza que desea  ordenar, usando el numero que le corresponda n ->'))

    if  pregunta == 1:
        print(f'mediana peperoni -> € {peperoni}')
        dinero -= peperoni
        total += peperoni
        ticket.append(f'peperoni -> {round(peperoni,2)}')
        print(f'tienes  disponible: € {round(dinero,2)}')
        break
    
    elif pregunta == 2:
        print(f'mediana hawayana -> € {hawayana}')
        dinero -= hawayana
        total += hawayana
        print(f'Tienes  disponible {round(dinero,2)}')
        ticket.append(f'hawayana -> € {hawayana}')
        break

    elif pregunta == 3:
        print(f'mediana 4 quesos -> € {quesos}')
        dinero -= quesos
        total += quesos
        print(f'tienes disponible -> € {round(dinero,2)}')
        ticket.append(f'champiñones -> € {round(quesos,2)}')
        break

    else:
        print('opcion no valida, porfavor  elija una opcion del 1 al 3')
        

# escogiendo ingredientes: 
while True:
    print(f'1.agregar complemento extra queso chedar -> € {queso_chedar}')
    print(f'2.agregar complemento pollo -> € {pollo}')
    print(f'3.agregar complemento champiñones -> € {champiñones}')
    print('4.No agregar ningun complemento')

    pregunta2 = int(input('¿le gustaria agregarun complemento extra?, porfavor elija una de las siguientes  opciones:n'))

    if pregunta2 == 1:
        print(f'complemento queso chedar € {queso_chedar}')
        dinero -= queso_chedar
        total += queso_chedar
        print(f'tiene  disponible -> € {dinero}')
        ticket.append(f' complemento queso chedar -> {queso_chedar}')

    elif pregunta2 == 2:
        print(f'complemento pollo -> € {pollo}')
        dinero -= pollo
        total += pollo
        print(f'tiene disponible -> € {pollo}')
        ticket.append(f'Complemento pollo -> € {pollo}')


    elif pregunta2 == 3:
        print(f'complemento de champiñones -> € {champiñones}')
        dinero -= champiñones
        total += champiñones
        print(f'tiene disponible -> € {champiñones}') 
        ticket.append(f'champiñones -> € {champiñones}')

    else:
        print('no se agregara  ningun complemento.')
        break

#imprimiendo ticket de  compra:
if total <= MONTO_INICIAL:
    print('No disponede suficiente dinero para realizar su compra, porfavor vuelva al ordenar.')

else:

    print('------ JORGE'S PIZZA--------' )
    print(f'su cambio es de: {round(dinero, 2)} n Muchas gracias por su compra! n QUE LO DISFRUTE!')

    for i in ticket:
        print(f' -> {i} ')
        break

se que mi codigo es muy malo y seguramente tengo muchos fallos, pero me harian un gran favor si pudieran decirme porque al añadir ingredientes no lo resta correctamente del valor introducido por el usurio al principio del programa, disculpen si me extendi demasiado, un saludo!

No consigo que una imagen se vea correctamente en React utilizando la Free Bootstrap Admin Template de CoreUI.

Este es el código del componente donde quiero que se vea la imagen:

Code:

import React from 'react';
import {
    CImage,
} from '@coreui/react';

const Asst = () => {
    return (
        <>
            <div style={{ display: 'flex', alignItems: 'center' }}>
                <CImage rounded thumbnail src="../../assets/images/image.jpg" width={200} height={200} />
                <h1 style={{ marginLeft: '10px' }}>Titulo</h1>
            </div>

            <hr />

            { /* Resto del código */ }
        </>
    );
};

export default Asst;

La ruta completa de la imagen sería esta:

C:proyectoproyectosrcassetsimagesimage.jpg

En la página se ve un cuadrado con bordes redondeados y dentro el típico icono de imagen rota. He comprobado la ruta y la extensión y parece estar correcto.

De momento todo lo tengo en local, no es una página funcional aún pero no sé cómo hacer para que se vea la imagen. He intentado también con el siguiente código:

Code:

<CImage rounded thumbnail src={require('../../assets/images/image.png').default} width={200} height={200} />

La única diferencia es que el icono de imagen rota no aparece y solo sale un recuadro en blanco de 200×200.

¿Alguna idea?

Datos típicos RStudio

Este es un ejercicio con datos inventados, pero he logrado que lo demás datos concuerde menos esos 3. Actualmente tengo un p-value de «p-value: 0.9991» y los demás datos si genera un efecto de línea diagonal, la intensión es tener todos los datos allí y no que me quede 3 datos por fuera

Imagen de R-Studio

Code:

library(readxl)
file <- "C:/Users/alfre/Downloads/Juana/baseDatos.xlsx"
datos <- read_excel(file)
head(datos) #Muestra las 6 primeras lineas

id_persona<- read_excel(file) #Variable dependiente
names(id_persona)

pairs(id_persona)
cor(id_persona)

regresion <- lm(id_persona ~ edad, data = id_persona) #Variable independiente edad
summary(regresion)

plot(id_persona$edad, id_persona$id_persona, xlab='edad', ylab='id_persona')
abline(regresion)

confint(regresion)
anova(regresion)

residuos <- rstandard(regresion)
valores.ajustados <- fitted(regresion)
plot(valores.ajustados, residuos)

qqnorm(residuos)
qqline(residuos)

tengo un inconveniente, quiero ocultar una parte del código html con php, para ello realizo algunas validaciones en php y si estas no se cumplen ocupo la función die(); logrando ocultar el contenido html, pero resulta ser que se oculta todo el contenido y solo quiero ocultar una parte de el. Estoy realizando esto a modo de prueba para ya pasarlo al script definitivo.

Adjunto el código y de antemano muchas gracias.

Code:

<?php
$error = '';
if(isset($_POST['submit'])){
    if(empty($_POST['usuario']) || empty($_POST['clave'])){
        echo 'ingrese un usuario y contraseña';     
    }else{
        $usuario = $_POST['usuario'];
        $clave = $_POST['clave'];
        if($usuario == 'jonhy' && $clave == '12345'){
            echo 'Usuario correcto';
        }else{
            die('error');
        }
    }   
}
?>

<!--Este parte igual debe seguir mostrandose-->
<div>
    <p>Codigo html a mostrar</p>
</div>
<!--Si falla la validacion, solo se debe ocultar el formulario-->
<form action="" method="post">
    <input type="text" name="usuario">
    <input type="text" name="clave">
    <input type="submit" name="submit" value="enviar">
    
</form>
<!--De aqui hacia abajo debe seguir mostrandose-->
<div>
    <p>Resto del contenido html que quiero que se muestre </p>

I saw the following result in a paper of Stephenson (https://arxiv.org/pdf/1412.6911.pdf, Lemma $2.2$), which is a variant of the Frobenius coin problem.

Let $n_1, . . . , n_p$ be $p$ non-negative integers and let $d = gcd(n_1, . . . , n_p)$. There exists integers $N_2, . . . , N_p$ such that the set of all sums ${ sum k_i n_i, k_1 in mathbb{Z}_+, k_i in {0, . . . , N_i} forall i in {2, . . . , p} }$ contains all large enough multiples of $d$.

Is there some $r$-dimensional version of it, in the sense that if one takes $X_1, . . ., X_p in mathbb{Z}^r_+$, there exists $N_2, ldots, N_p$ such that the set of sums ${ sum k_i X_i, k_1 in mathbb{Z}_+, k_i in {0, . . . , N_i} forall i in {2, . . . , p} }$ contains all elements of a certain subgroup of $mathbb{Z}^r$ that are in a given affine cone of $mathbb{N}^r$ ?

Thanks!

We have a strictly increasing measure $mu$ on $[0,infty)$ given by $mu(0,x):=int_{0}^{x}e^{X(s)-frac{1}{2}ln1/epsilon}ds$, where $X(s)$ is a mean zero Gaussian field with truncated log covariance $R(|t-s|)=E[X(s)X(t)]=ln(frac{delta}{epsilon vee |t-s|wedge delta})$.

Apparently very little is known about the inverse $T_{a}$ of this measure i.e. $mu(0,T_{a})=a$. In computing the moments of increments $E[(T_{b}-T_{a})^p]$ for $0<a<b$ we end up with having to understand moments for the shifted $mu(T_{a},T_{a}+t)$ (analogous to «Slepian process») and thus understanding $e^{X(T_{a}+s)}$ (even the expectation $E[e^{X(T_{a}+s)}]$ is hard to understand).

I list here some references and ideas in estimating $E[mu(T_{a},T_{a}+t)^{q}]$.

  • If X is further an Ito process, then one can use a change of variables to study $e^{X_{T_a}}$ («First Hitting Time of Integral Diffusions and Applications»)
  • For example, in the case integrated geometric Brownian motion, one has $e^{B_{T_a}-frac{1}{2}T_{a}}$ be equal in law to squared Bessel. Even possible to get Laplace transform for the inverse $T_{a}$.
  • Another hope is to use Malliavin calculus to study that shifted process. One promising route is «Hitting times for Gaussian processes» where they study $e^{X_{tau_a}-R(tau_{a})}$ for $X_{tau_{a}}=a$, but some of the techniques can be modified to study $e^{X_{T_{a}}}$ instead. That work can be generalized to hitting times of additive functionals $mu(x)=int e^U$ i.e. $mu(T_a)=a$. This is because instead of taking Malliavin derivative of the supremum at lemma 3.2, we can take that of $mu(x)$.
  • A beautiful result would be to bound by the unshifted moment $$E[mu(T_{a},T_{a}+t)^{q}]leq c E[mu(0,t)^{q}],$$

for some uniform bound $c=c_{q}$. Usually such proofs go by Gaussian-interpolation but here $X_{T_a}$ is most likely not a Gaussian anymore. So one hope is to use the generalization of interpolation in Malliavin calculus «Comparison inequalities on Wiener space». The issue here is that one seems to necesarily need Malliavin differentiability of $X_{T_a}$, which is not for similar reasons as here possible.

Is there a centered-hexagonal, triangular, square (apart from 0 and 1)?
In other words, is there a positive integer that is simultaneously

(1) a perfect square, $n^2$, $n ge 2$,

(2) a triangular number, $frac{m(m+1)}{2}$, $m$ an integer,

and (3) a centered-hexagonal number, $(p+1)^3 — p^3$, $p$ an integer?
