Component Reliability Analysis Much of our work involves determining the reliability of components, where we want to understand how long they will last before failure. We use statistical analysis to predict these failures in terms of the expected number of hours used, miles driven, etc. Say we are given...
This post is part 2 of a series on Data Manipulation in R. In part 1, my colleague showed the uses of the data.table package. In this part I will explore the dplyr package using the same examples used in part 1. What is dplyr? dplyr is a package...
data.table?In the R programming language, data.table is both a package and an object within that package. The data.table package serves as a wrapper for the data.frame object in base R. A data.table object features many enhancements over a data.frame – to include increased speed and memory allocation efficiency. The...
The modern field of Artificial Intelligence (AI) is perhaps, not so modern but rather a journey over almost three centuries of improved workflows to create more efficient and responsive processes. AI in its current state is not a replacement for human intelligence and ingenuity but rather a support tool....
The DoD’s Underperforming Aircraft Mission Capability Rates From a glance, the US Military’s aircraft mission capability rates are underperforming across the board. A Government report released in November of 2020, reviewed 46 aircraft systems and found that only three met their annual mission capable targets in the majority of...
Tackling Aircraft Down-Time An aircraft’s job: to take off and land reliably, safely, and efficiently. As we look at today’s technologies and tomorrow’s advanced predictive tools, we believe that fleet health will increasingly be measured and analyzed in real-time, while fleet maintenance will be scheduled based on digitally predicted...
Post-COVID Aviation Operating Landscape will be Catalyzed by Digital Transformation says ICAO Post COVID-19, aviation companies require more than existing infrastructure to adapt to new realities. Behind every flight is a carefully orchestrated tech ecosystem that forecasts based on a variety of macro and micro trends: consumer demand (business...
My name is Christina; I’m a data scientist at Freya Systems who previously worked for the NYC Department of Education. I want to share with you an important skill for data analysts at any stage of their career: communicating your reports effectively so decision makers are more likely to...
I was recently doing a project utilizing the Yelp API and analyzing restaurant data through R. Leaflet proved to be very helpful in providing interactive maps to visualize data. It didn’t hurt that the maps were very easy to generate and customize as well. In this post I’ll go...
