SUMMARY Humans around the world rely on the internet for entertainment, education, and essential services. Unfortunately, much of the internet is inaccessible to users with hearing impairments or vision impairments. Inaccessibility affects millions of people: 26 percent of Americans are disabled according to the CDC. Among disabled Americans, 5.8 percent are…

A Brief Technical Description SUMMARY The need for cost-efficient data processing is growing quickly. Edge computing is a type of computing architecture that brings computation as close to the source of data as possible to minimize latency, the time it takes data to travel through a system. Engineers often use edge…

Using historical regular season data, I evaluated scoring trends in the NFL. Specifically, I compared scoring trends of the away team to scoring trends of the home team. From 2015–2019, the home team won 56.3% of regular season games. Here’s the frequency distributions of each final score: Over/under bettors are typically interested in the cumulative distribution of scores. Using the figure below, we can estimate the probability that a team will score less than a certain number of points in a game.

An IIFE (Immediately Invoked Function Expression) is a JavaScript function that runs as soon as it is defined. How to use an IIFE IIFEs can be used to conditionally assign values to immutable variables. This is achieved using an unnamed function that is evaluated exactly once when the variable is declared. …

One of the simplest methods of simulating fluctuations of equity pricing over time is by using a binomial return distribution. At each interval, there can only be two outcomes: the price rises by a fixed percentage or falls by a fixed percentage. We can define 3 inputs to the model: …

Equity options are financial derivatives allowing investors to obtain risk-return profiles not possible through the simple purchase of equity. Although options have existed for decades, the amount of options bought and sold has increased dramatically in 2020. In fact, the world’s largest equity derivatives clearing organization reported that 545,272,318 contracts…

The following functions and operators are used to manipulate strings in Python 3. membership operator The ‘in’ operator can be used to check if a substring exists in a string. 'hell' in 'hello' # True 'i' in 'team' # False 'a' not in 'the quick brown fox' # True slicing Much like lists…

Recently I’ve gotten exposure to various mobile applications using location based contact tracing. These apps are used to calculate who you’ve been near based on recorded GPS data. In location-based contact tracing, one calculation is essential: the distance between two points. How can we tell if two users crossed paths…

What happens when a supersonic fluid flow collides with a forward facing step? Decades ago, scientists around the world scrambled to develop methods to accurately simulate this scenario using computational fluid dynamics (CFD). …
