Lecture 5: Grounding Techniques PCB
No full textThis video was created by Neha Kardam and is part of a series of lectures on printed circuit board design using Ki-CAD software. During this lecture, Kardam covers star grounding, analog and digital separation, ground planes, and slotted ground planes. The lecture examines the theory and practical challenges of star grounding, emphasizing the importance of separating analog and digital circuitry to minimize noise. Grounding strategies for analog-to-digital converters, the benefits of ground planes, and  techniques for managing digital currents in analog return paths are also highlighted.This video runs 19:40 minutes in length. Additional videos from the series are available to view separately
Soil Variability
No full textThis resource from Northeast Community College includes an activity and presentation related to soil variability. In the activity, students use cups and a 7x7 grid to learn about the concepts of soil sampling and soil availability. The 7-page teacher's guide features an activity timeline with instructions and tips for each part of the activity, including a post-activity instruction. Also included are materials needed, learning objectives, and setup information. The 4-page student worksheet includes instructions, questions related to the activity, and a brief introduction to precision agriculture, soil variability, and soil sampling. Upon completing the activity students should be able to:Demonstrate different soil sampling methods and observe how data can be interpreted differently when looking at different parts of the field versus the wholeUnderstand the purpose of soil samplingDefine variability and explain some of the data we receive in soil test reportsThe presentation provides background information on precision agriculture and soil availability with review questions
Interview with Ted Wilinski, Building Automation Systems Program Coordinator at Milwaukee Area Technical College
No full textThis video from the Building Efficiency for a Sustainable Tomorrow (BEST) Center features an interview with Ted Wilinski, Building Automation Systems (BAS) Program Coordinator at Milwaukee Area Technical College. Wilinski begins the interview by sharing prior professional experiences, including working as an industrial service engineer and energy conservation consultant. These experiences led Wilinski to develop the BAS program at MATC. Wilinski describes the development and structure of the program, including collaborating with an industry advisory committee to meet industry standards. The interview covers the program capstone, lab facilities, and opportunities for hands-on learning. Wilinski discusses student engagement and retention strategies, and identifies career paths the program prepares students for.This video runs 00:26:39 minutes in length.

System Hardening: (Part 1 of 3)
No full textThis video, presented by instructor Tony Hills from the Cybersecurity Education for Advanced Manufacturing Organizations project, is the first part in a series of lectures on system hardening. Hills begins the video by introducing the objectives of the series and defining system hardening. Next, Hills focuses on the importance of choosing good passwords, discussing poor password hygiene and the use of passphrases to create highly secure passwords. Provided are examples of secure and insecure passwords.This video runs 12:56 minutes in length. Additional videos from the series and a related training scenario are available to view separately
Wound Rotor Induction Motors (Part 2 of 2)
No full textThis video, published by Columbia Gorge Community College, is the second part of a two part lecture on wound rotor induction motors. The lecture covers "the construction and theory of operation of wound rotor induction motors as well as examine their mechanical and electrical properties while in operation." In this video, presenter Jim Pytel discusses motor resistance, variable resisters, and their effect on the shape of the speed torque curve. Pytel then compares no resistance, low resistance, and high resistance wound rotor induction motor configurations, analyzing the speed torque curve, mechanical power, inrush current, real power, and efficiency of each.This video runs 11:37 minutes in length. The first part of the lecture is available to view separatel
Secondary Resistor Reduced Voltage Starters (Part 2 of 2)
No full textThis video, published by Columbia Gorge Community College, is the second part of a two part lecture on secondary resister reduced voltage starters. The lecture examines "hard wired relay based ladder logic and programmable logic controller or PLC based implementations of single step and staged secondary resistor reduced voltage starter." In this video, presenter Jim Pytel demonstrates the PLC implementation, discussing its advantages, operation, and contrasting it with the single staged hard wire relay based ladder logic implementation.This video runs 10:04 minutes in length. The first part of the lecture is available to view separately
3 Phase Transformers (Part 3 of 3)
No full textThis video, published by Columbia Gorge Community College, is the third part of a three part lecture on 3 phase transformers. In the lecture, presenter Jim Pytel covers the design, configuration, operation, and uses of 3 phase transformers along with "electrical devices used to step up, step down, isolate, change the electrical configuration, and phase shift 3 phase AC voltage." Also covered standard 3 phase AC transformer naming conventions, simplified connection diagrams, displacement diagrams, and examine common Y, delta, and Z configurations. In this video, Pytel discusses zigzag connected transformers and when it may be necessary to use a 3 phase transformer.This video runs 15:49 minutes in length. The other parts of the lecture are available to view separatel

No full textThis video from the National Cybersecurity Training and Education (NCyTE) Center features a panel discussion on artificial intelligence (AI) and its impact on cybersecurity instruction and the cybersecurity workforce. After a brief introduction summarizing AI's effect on labor, each cybersecurity expert panelist discusses their work with AI and covers topics such as preparing workforce and faculty members for AI, integrating AI into classroom instruction, and AI in other disciplines.The video runs 57:33 minutes in length
Decarbonization of Domestic Hot Water Generation Lab
No full textThis video from the Center for Renewable Energy Advanced Technological Education (CREATE) National Energy Center features a presentation by James Horst, faculty at Delaware Technical Community College. Horst outlines a laboratory activity in which students test hot water generation with a gas stove, electric resistance, and a heat pump, comparing the carbon emissions of each hot water generation technique. This activity is designed to engage students in a conversation about the environmental impact of everyday activities and steps that can be taken to reduce that impact. This video provides a step-by-step overview of how to facilitate this activity, including required materials and learning outcomes.The video runs 00:24:08 minutes in length
Zero Trust
No full textIn this video, published by the National Cybersecurity Training and Education (NCyTE) Center, Shaya Wolf from the Idaho National Laboratory discusses research on integrating zero trust practices into Industrial Internet of Things (IIoT) architectures. Wolf goes into the process of proving system validation and security assurance with anti trust, discussing aspects of research such as data collection, research measures, and research results.
