Train Scholarship (Genaro Rivera)

  Ascend Project Team Sky High This week, I decided to focus on the weather balloon project. Above is the video (I am not sure if the video works, so I included images) of our HD Run Cam from our payload. We had a 4k camera facing the horizon and an HD pointing up at the balloon. However, the 4k camera shut off 8 minutes after recording; the total flight time was 2 hours. Fortunately, despite pointing up at the balloon the entire time, the payload flipped upside down for about 6 seconds which allowed for amazing footage of the horizon. Alongside the cameras, we had a pressure sensor, two temperature sensors, and an accelerometer. We had our pressure data. The first few minutes, the pressure remained constant because we switched to flight data recording mode but stood around ensuring everything was good before launching. The pressure starts to decrease right at launch. This is due to the air molecules not being as tight as alongside there being less gravitational force as you increa...

 Genaro Rivera December 2, 2022 MATLAB user-defined functions This week I decided to make a script that computes the gravitational force (in Newtons) between two bodies (m1 and m2) in kg and distance (r). Specifically, the force between the Earth (5.97*10^24 kg and 6371 km) and I. To make things simpler I decided to break the script into three user-defined functions. This week I went over user-defined functions. A user defined function is unique. For example, a built-in function would be something like the max function (finds the highest point) or the avg function (finds the average from a list of numbers) where MATLAB computes the function in the background. A user defined function does the same except, the user makes and customizes the function. Above is an example of a function I made that converts between pounds (my weight of 120 lbs) and kilograms. To convert from pounds to kilograms, I selected option 1 ([Weight] = Pound_Kilogram(120, 1)). The second picture is an example of ...
