The Current Energy Dilemma in Water Treatment The critical component of water and waste treatment processing is the common architecture of electric motors and controls. In the United States, the treatment process is driven by electric motor-driven devices, including energy-intensive pumps. Studies and publications from the past ten years...
Our impact is measured in how we equip clients with predictive models and decision tools to be more effective, efficient, and safe in their operations. We employ data strategies to fuel condition-based maintenance models and customize dashboard tools so that clients are making data-driven decisions. We are most acutely...
Towards the end of 2021, Freya hosted a hackathon that split the team into two separate factions asked to solve a distinct set of computer vision problems. The resulting days allowed for collaboration and problem solving that really got the data science juices flowing. Two Real-World Problems Each team...
Before becoming a data scientist, the way data appeared on a web page seemed like magic (to be honest some parts of the process still feel that way!), but having been involved in many aspects of the data pipeline at Freya Systems I wanted to share an overview of...
According to IBM Research: “Software development refers to a set of computer science activities dedicated to the process of creating, designing, deploying and supporting software.” Software itself is the set of code that tells a device what to do. The software could be for an individual job function or...
The Goal As a data scientist you often find yourself creating a notebook documenting a new model or an update to an existing model. Recently in this particular situation I was analyzing how my model was performing within windows of time throughout the prediction window. I wanted a visualization...
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...
