Q&A: Radar Scanner Position - Attainable Adventure Cruising
Saved by uncleflo on February 13th, 2022.
Question: What is your preference regarding the best place to mount a radar antenna? As far as we can tell from the pictures of Morgan’s Cloud you have mounted yours on a pole aft. Our previous experience with radars tells us that the antenna should be as high and free as possible. Wouldn’t a radar antenna mounted on the mast just above the first spreaders give better range and a more detailed radar picture than if it were mounted lower? It also appears from the pictures that your antenna isn’t mounted in a way that makes it able to tilt so that it can compensate for heel of the boat when sailing. Answer: First off, we should say that we view radar as the most important piece of electronic equipment on Morgan’s Cloud—yes, more important than GPS, since we can find our way with a compass and sextant but we can’t see unlit objects at night or through fog—so we have given a lot of thought to the position and installation of our radar scanner. We prefer a pole mounted aft for the scanner over mast mounting.

AgustaWestland Project Zero - Wikipedia
Saved by uncleflo on December 22nd, 2019.
The AgustaWestland Project Zero is a hybrid tiltrotor/Lift fan aircraft. It has been developed by AgustaWestland as a technology demonstrator, and is used to investigate all-electric propulsion and other advanced technologies. It is the world's first electric tiltrotor aircraft. In December 2010, AgustaWestland's management approved the formation of a team under James Wang with the intention of producing a technology demonstrator incorporating as many new innovations as possible on a single airframe. Speaking in 2013, Wang noted that electric technologies were rapidly advancing, and that the function of Project Zero was to achieve readiness with electric aircraft technologies: "Rather than waiting for the battery to become even better, then working on electric aircraft technology, the team has positioned itself to be ready for the next generation of batteries".

Mandrel Pipe Bender | Useful Tools | Pipe Bending Tools | Plumbers Tools | UK
Saved by uncleflo on August 13th, 2019.
For those who need a tighter bend radius we have designed the Useful-Tools hand operated mandrel tube bender. These machines will allow tubes to be bent with an impressive 2 times tube diameter bend radius with no rippling or cracking of the tube and the absolute minimum of distortion. We have 2 machines that all operate on the same principle, namely the pipe or tube to be bent is located between a formed mandrel and back plate with another formed internal mandrel (bullet) held at a carefully controlled position inside the tube. The tube is secured firmly to the main mandrel and when the mandrel is turned the tube is pulled over the internal mandrel as it wraps around the main mandrel. (This internal "Bullet" holds the tube open and helps reduce distortion to a minimum.)

Sensor Fusion Algorithms For Autonomous Driving: Part 1 The Kalman filter and Extended Kalman
Saved by uncleflo on July 24th, 2019.
Tracking of stationary and moving objects is a critical function of Autonomous driving technologies. Signals from several sensors, including camera, radar and lidar (Light Detection and Ranging device based on pulsed laser) sensors are combined to estimate the position, veloctiy, trajectory and class of objects i.e. other vehicles and pedestrians. A good introduction to this topic can be found at: http://www.onenewspage.com/video/20161006/5695999/Mercedes-Benz-presents-the-Sensor-Fusion-at-2016.htm

MarineTraffic Online Services enable you to monitor, review, analyse and plan shipping operations
Saved by uncleflo on November 29th, 2018.
By reporting your own positions, MarineTraffic will be able to display your vessel on the Live Map. Visibility: Real-time vessel positions displayed on the MarineTraffic Live Map are extremely useful to a wide spectrum of users closely-related to the shipping industry one way or the other. To name a few, ship owners, agents, pilots, tug operators, port authorities, crews' families and friends, passengers, cargo handlers or recipients, brokers, leisure boaters, sailing racers, ship chandlers, bunkering companies, yacht charterers or brokers may have a reason to monitor the positions of your vessel. The list of interested parties is unlimited while the numbers speak for themselves; the visibility of the MarineTraffic website is such that the number of visitors per day well exceeds the half a million mark! Safety: Although MarineTraffic is not intended to be used as a safety tool, there are many cases where making your position widely known could enhance your safety at sea. Making your position known to the public may be complementary to the official means of distress reporting (such as EPIRB or DSC radio) and may help in Search & Rescue (SAR) procedures where the position of the vessel cannot be acquired by other means. Historical data: MarineTraffic stores historical data in its database. Historical data regarding the past movements of your vessel could be accessed for many reasons; such as just for fun or recollection, for statistical reasons, for analyzing tracks in comparison to weather conditions, for accident investigation etc. Consider it as an online log of yours!

Fiddle to experiment with browser element offsets/sizes

Stackoverflow - offsetTop vs. jQuery.offset().top
Saved by uncleflo on May 9th, 2018.
I have read that offsetLeft and offsetTop do not work properly in all browsers. jQuery.offset() is supposed to provide an abstraction for this to provide the correct value xbrowser. What I am trying to do is get the coordinates of where an element was clicked relative to the top-left of the element. Problem is that jQuery.offset().top is actually giving me a decimal value in FFX 3.6 (in IE and Chrome, the two values match). http://jsfiddle.net/htCPp/ exhibits the issue. If you click the bottom image, jQuery.offset().top returns 327.5, but offsetTop returns 328. I would like to think that offset() is returning the correct value and I should use it because it will work across browsers. However, people obviously cannot click decimals of pixels. Is the proper way to determine the true offset to Math.Round() the offset that jQuery is returning? Should I use offsetTop instead, or some other method entirely?

Any Time™ DatePicker/TimePicker AJAX Calendar Widget - HTML5, AJAX, JSON and XML Consulting and Training by Andrew M. Andrews III (SM)
Saved by uncleflo on June 13th, 2015.
It seems like there's a million calendar and clock widgets out there, and when you look past the eye-candy, they all have one thing in common: they're tedious at best. At worst, counter-intuitive. Sure, a picker that uses sliders or spinners, or looks like an analog clock face might be cute, but did you ever notice how long it takes to position one to the correct hour and minute? Or how about choosing a month that's more than a season away? Worse yet, entering your birth year on a datepicker that forces you to click... backwards... repeatedly... one... year... at... a... time? Does your favorite "pretty" picker even work if your user has a keyboard, but not a mouse? Does it scale larger if the user increases the text size on your page? If not, ask your legal department how they'd feel about an accessibility lawsuit!

Getting the Mouse Click Position in JavaScript | kirupa.com
Saved by uncleflo on January 20th, 2015.
For all sorts of interactive doo-dads you will be creating, chances are you will be making heavy use of the mouse (or another pointing device like a stylus or finger). Something you may find yourself needing to do is figuring out the exact position of the click. In this tutorial, I will explain the magic behind figuring out the exact pixel coordinates of where a click occurred. While the words "mouse" and "click" will appear often, just know that everything I show here works on a touch device where a stylus or your finger is the pointing thing!

Now consider the case of compressive loads and the instability they can cause. Consider only static instabilities (static loading as opposed to dynamic loading [e.g., flutter]) "A system becomes unstable when a negative stiffness overcomes the natural stiffness of the structure." Review some of the mathematical concepts. Limit initial discussions to columns.

Monte Carlo Localization
Saved by uncleflo on March 29th, 2012.
Monte Carlo Localization, also known as Particle Filtering, is a relatively new approach to the problem of robot localization - estimating a robot's location in a known environment, given its movements and sensor reading over time. In this project you are to solve the global localization problem, where the robot does not know its starting position but needs to figure out where it is. (This is in contrast to the position tracking problem, where the robot knows its starting position and just need to accommodate the small errors in its odometry that build up over time.) To make things a bit simpler, you will solve this problem in a one dimensional world. Since the on-board computation abilities of the RCX are limited, we remote control the robot from a base computer. You are given skeleton programs for the robot and base computer, which are described below.
