Following on from the 3D plots of the Earth globes in comments to an earlier post, here's some hacky code to grab longtitude and latitude.

(nb. This code attempts to send the IP address of your primary DNS to www.geobytes.com so don't run it if you don't want that action.)

if kernelopts(platform)="windows" then
   res:=ssystem("ipconfig /all"): res:=res[2];
   StringTools:-Search("Primary Dns Suffix",res);
   ans:=StringTools:-Split(res[%+36..%+70])[1];
else
   ans:=ssystem("hostname -y"...

Recently, I published the following paper.

"Calibration of a radiocarbon age", Nonlinear Processes in Geophysics, 19: 345–350 (2012).

The paper explains that all radiocarbon dates are inaccurate, due to an error in the handling of the statistics.

The paper has a Supplement, which includes a program to do the statistics correctly:

We have been using MapleTA for many years (since version 1.5) and have version 8 hosted on a Maplesoft server. Recently, we looked into buying the Blackboard connector. It is disappointing that we have not been able to go through with this because of an inadequacy in the connector. As I understand it from our technicians, in Blackboard a course is identified by four attributes ID, year, calendar and title. These account for different presentations of the same course in different...

Eleven new Clickable-Calculus examples have been added to the Teaching Concepts with Maple section of the Maplesoft website. That means some 74 of the 154 solved problems in my data-base of syntax-free calculations are now available. Once again, these examples and associated videos illustrate point-and-click computations in support of the pedagogic message of resequencing skills and concepts.

This message has been articulated in ...

This post is a further exploration of the optimization problem of finding a point on f(x) = sinh(x) - xe^-3x closest to the point (1,7).  The problem is part of our Teaching Concepts with Maple web site, a collection of video examples and Maple worksheets designed to illustrate how Maple can be used to generate...

I guess there is a limit bug here somewhere.  With MultiSeries things are OK...

L:=(x*BesselI(k-1, x)+x*BesselI(k+1, x))*BesselI(-k, x);
L := (x BesselI(k - 1, x) + x BesselI(k + 1, x)) BesselI(-k, x)
simplify(limit(L,x=0)) assuming k>0;
                               0
with(MultiSeries):
simplify(limit(L,x=0)) assuming k>0;
                          2 sin(Pi k)

This is a comment and warning to anyone in the United States using MapleTA 8. 

If you get login information using LDAP, MapleTA 8 gets the "employee number" from the LDAP data base  and displays it on the screen when a person is logged in.  After talking to our IT people, they acknowledge that this is a FERPA violation when using MapleTA in a lab where people can see screens of other people's computers.

Our IT people have contacted Maplesoft for...

I wanted to point the MaplePrimes community in the direction of the new MapleSim training videos. These videos cover a variety of common tasks within MapleSim, and demonstrate the concept in just a few minutes each. I'd highly recommend you take a look at them to learn more about using MapleSim.

They're located here: http://www.maplesoft.com/support/training/videos.aspx

MapleSim has seen a rapid evolution since its inception in 2008 as a multi-domain system-level modeling and simulation environment. Market response has been outstanding: Maplesoft has been working with an expanding list of key industry players such as AISIN AW Co., Ltd. and B&R,  while major customers like

It is the first time  I post a Maple bug in MaplePrimes because I use to submit an SCR.
There is a serious reason to do so. Let us look at the output of
> with(plots):
> implicitplot(sqrt(x^2+y^2)-sqrt((x-4)^2+(y-3)^2) = 5, x = -20 .. 20, y = -20 .. 20,
numpoints = 10^6, thickness = 5, scaling = constrained);
(both in Maple 13 and in Maple 16)

Saying 'logout' through the menu bar does not log me out.

I am still logged in (even after leaving the pages).

And I guess, that the according cookie is not properly cleared.
But it should.

1 Introduction

Three tanks are connected with two pipes. Each tank is initially filled to a different level. A valve in each pipe opens, and the liquid levels gradually reach equilibrium. Here, we model the system in MapleSim (including the influence of flow inertia), and also derive and solve the analytical equations in Maple.

I would like to pay attention to http://www.ams.org/samplings/feature-column/fc-2012-08 , where a mathematical experiment is applied.

Viewing an html application at the application center results in some problems which doesn't allow to view the application in it's html format.

I had responded to a maplesoft application where data to a .mw worksheet was no longer available and had asked them to find and fix it.

I would have hoped a response would have been put here to mapleprimes to find the data.  Unfotunately the data could not be found and the application was deleted from the application center. 

It was Analyzing Data files in Maple - Maple 10 and Maple Net - Nov 7, 2005
