September 15 - October 15 is Hispanic Heritage Month. As a member of the LatinX Enterprise Leadership Team for Baker Hughes, we chose to celebrate by virtually touring several of the Latin countries. To make this more engaging, I created a virtual "scrapbook" where employees could share images in a community area, building a combined scrapbook of the month's events. Upon logging in, they are given their own unique page. They can upload images, resize and move them, and even apply a shape filter. They can select from several pre-selected background options. As the month progresses, they can also earn exclusive items for their scrapbook by attending events and earnign a short-lived link. At any time, they can view the combined book and interactively swipe the pages, like a real book. At the end, they can download the entire book as a PDF. All settings and options are controlled via the admin portal, so exclusive content could be generated as the events occured.

This will be the 3rd year of the OSU & BH Hackathon!! :)

Description:
Part of our work with LatinX is to empower and upskill employees. As part of that, I hosted a "follow along with me" training where ~80 to ~300 employees learned "coding for non-coders". The 6 part series covered: installing python + vs code, making a game, working with excel docs, version control, understanding the internet, and getting data from the internet.

September 15 - October 15 is Hispanic Heritage Month. As a member of the LatinX Enterprise Leadership Team for Baker Hughes, we chose to celebrate by virtually touring several of the Latin countries. To make this more engaging, I created a virtual "time travel machine" map where employees could travel along with the events. They dragged their time machine around on the screen to fly through time and land on different portals. As each team member attended HHM events, they were challenged with trivia that matched the events. If they solved the trivia, new clother or changes to their avatar became available! For the geeks out there, everything is configurable through and admin section of the website, including the portals, their questions, and the available rewards. No need to mess with the DB manually. :)

It�s time to feel the POWER! __ If you are thinking about the gym� haha� nope� we mean the Microsoft Power Platform. __ That means: Power Apps, Power Bi, and Power Automate. In our next session, we will have another awesome guest Mohammed Alkuhlani, organizer of the Citizen Development Community, to share some know-how, simple examples, data consolidation, and ways to drive insights. If you aren�t already familiar, I expect a little bit of __. I�m sure that will leave you curious and wanting more. __ Side comment: �I personally know nothing about the Power Platform, so I am also equally excited for this session.� - Christopher

It�s time to get organized, again! __ This time with passwords! That means no more funny password pattern schemes, no more memorizing phrases, and definitely no secret old post-it notes stored in the back of a drawer. __ Join us in this very interactive session where we will set up BitWarden (password manager) together. We�ll create a free account, add it to our computer(s), add it to our phone(s), and most importantly add a couple passwords to show how it works to easily login. If time permits, we�ll explore migrating passwords from Chrome.

It�s time to get organized! __ Yep, that means no more old post-it notes with coffee stains, random notepad docs labeled �to-do/today/this-week/urgent/now�. Come on, it�s 2022 and... we have more task management tools and techniques than actual tasks. __ So... let�s pick a few and see what we can do with them! I�m still interviewing you all for tips/tools/techniques, but... I imagine we�ll at least discuss To Do, Planner, OneNote, and Excel. Also... who doesn�t like a bit of accountability? I mean, it works at the gym, so it should work at work too, right?! We�ll show how to use those same tools to be committed. For now at least, I expect to show the Eisenhower Matrix and sprinting.

Description:
Baker Hughes has a long history and hence several past tools for organizing projects. After the recent migration of many projects to GitHub, we needed something to make sense of it. The Inner Source Portal borrows ideas/parts from existing open source project to scan thousands of repositories over a few big orgs. It catalogs several things, stores it in a middle layer, and then associates an "inner source score" based on how useful, collaborative, and well organized the project is.

Description:
We are BACK! __ Get ready for some interactive learning sessions with MS tools (and BH tools). Office, Excel, MS Teams, OneDrive, and SharePoint, are definitely our favorite apps! __ But� they change all the time� and we get busy� and then we get behind. There are just so many features� and we are not aware of all the capabilities these tools bring, and how they can help us maximize our day. Plus it is challenging to learn by just watching. __

September 15 - October 15 is Hispanic Heritage Month. As a member of the LatinX Enterprise Leadership Team for Baker Hughes, we chose to celebrate by virtually touring several of the Latin countries.

Description:
A reinforcement learning approach is used to train a Markov Decision Process, which enables the creation of a short and highly accurate decision tree. This use of reinforcement learning enables classification without the downsides of traditional tree creation methods, which usually require prior knowledge, greedy separation techniques, and pruning. Additionally the use of reinforcement learning enables additional functionality such as stream learning, concept drift support, per-feature importance weights, adding of features, removal of features and classification of incomplete data vectors. Finally, an evaluation across various parameters shows the influences of training order, discount factor, exploration rate, concept drift, and feature space on the accuracy and generated policy size, thereby providing insights into the capabilities and limitations of a reinforcement learning based decision tree. (Note: This journal was not submitted.)

Description:
An adaptive stream-based process is described for learning a set of vocabulary to control a black box. The method serves to accurately discretize the value space, enable tracking, and identify simple patterns. These values and patterns become the system knowledge (or vocabulary) and are used for training a reinforcement learning based decision tree. An interpretation layer enables developing higher level knowledge with time, creating an easy-to-read policy of the black box functionality, providing control information. Tests are performed to demonstrate the effectiveness and limitations with open-loop systems. Finally, a proposal is made for further knowledge identification, closed-loop systems, and learning with less prior information.

The rubber in a motor is affected by chemicals and/or temperature and swells, increasing friction and damages. To offset this, the rotor is typically deliberately undersized. Hence there is usually a break in period. To avoid this break in period, a tempory coating is introduced into the system. This temporay coating fills the gap ensuring higher hydraulic efficiency. As the swelling occurs, the coating is removed (by various different means).
