Nevertheless, the satellite service times of the DT did not accurately reflect actual service times, which tended to be significantly longer. Moreover, as the DT was designed to be launched at the end of the working day, measuring the satellite speed in real-time would not have been possible. To address this issue, we ...

mobile robot is a self-contained automaton that can wholly move with respect to its environment. There is no direct way to measure a mobile robot’s position instantaneously. Instead, one must integrate the motion of the robot over time. Add to this the inaccuracies of motion estimation due to slippage and it is clear t...

- If the I gain is too high: you will see slow oscillations. - If the I gain is too low: this is best tested in Acro mode , by tilting the vehicle to one side about 45 degrees, and keeping it like that. It should keep the same angle. If it drifts back, increase the I gain. A low I gain is also visible in a log, when th...

I rolled the plane out immediately, but again by the time I reached the runway it was blowing 25 knots from 250 degrees. Since a runway flight is a fairly delicate maneuver, requiring precise handing of an airplane with whose responses one is not yet familiar, a gusty quartering crosswind is not recommended. I held for...

So I moved on to write a function to move to a specified distance, say 1 metre. I timed the time required to move one revolution and calculate the specified distance by the distance of one revolution, and get the number of revolution required distance. However, I found this trick does not work, because the time for the...

Surface acoustic sensors detect the mechanical waves that propagate through or on the surface of the solid materials. They typically use piezoelectric effect to convert the wave into an electric signal, such that changes made to the mechanical wave are reflected in the output electric signal. Surface acoustic sensors m...

Hybrid reward surpasses model-based verifiers across all the three regimes. To further assess whether hybrid reward learning can outperform existing model-based verifiers, we compare HERO against two representative systems: General Reasoner, a frozen 1.5B verifier model that provides binary correctness judgments (Ma et...

The second formula for the updated ( a posteriori ) estimate covariance above is known as the Joseph form that is often used in applications (numerically more stable than the more simple usual formulation). Proof of the formulae is found in the derivations section, where the formula valid for any K k is also shown.

On the example of muon decay; let’s take, instead, the scattering of an electron off a positron to make a W+ and W-. There are three interfering processes, one with a virtual photon of positive mass-squared, one with a virtual Z of positive mass-squared, one with a virtual neutrino of negative mass-squared. Are they al...

Control of the DC brush motor is simple. Just connect the voltage to them and they start working. They slow down when the voltage is lower, and when the voltage is reversed, they turn in a different direction.

Referencing Figure 4, we create 4 different course structures. The first has only finals, testing all 6 concepts in the four-concept course at the end FF. The second has a midterm-final structure, testing PR1, PR2 and CA at MM and CB, CC, and CD at FF. Finally, we have a quiz structure that uses all 4 examinations Q1Q\...

At the end of last season, we had two members graduate, Austin and Tycho. Their upcoming "goodbye" posts will be posted here, the same as last year. So, we wanted to recruit at least one member to replace them. Recruitment methods that we had used in the past, such as posters and Townview recruitment seminars, had fail...

I felt some connection to this project because my friend Hans Kandlbauer had been its chief engineer and aerodynamicist; I had also helped design the tip tanks. Although the airplane was very fully equipped (glass cockpit, etc) and loaded with 450 gallons of fuel, it had a 315-hp Lycoming and should have had a pretty r...

Road salt is used as a common de-icing agent, but excessive application poses several environmental risks. This includes water contamination, soil degradation, and harm to aquatic life. This research investigates temperature-dependent coatings for road salt optimization, reducing unnecessary application, and as a resul...

The rapidly exploring random tree (RRT) algorithm typically starts with the initial point as the root node and generates a random search tree by randomly sampling and adding child nodes in the space. When the child nodes in the random search tree include the target point or enter the target area, a path made up of tree...

Continuing with the watch example, if you checked your watch and then waited for what you thought was an hour but according to your watch had only been 54 minutes, then you are probably more inclined to believe the measurement and discount your prediction. This is exactly the thought process behind a Kalman Filter. I...
