Example of Substation Maintenance & Assessment Audits for Training - Niels In...Niels Inderbiethen
This is a good example of an audit which explores all the substation attributes, equipment & maintenance requirements and is usually the basis for creating a professional site specific Training Manual which I then finalize with the client and prepare the documentation for formal training of any new staff to the plant, together with Regulations & ORHVS training. This documentation can then also be forwarded to the SETA & SAQA for formalization and educational points allocation. It also forms a critical part of any plants record keeping requirements and plant maintenance inspections and complies with regulatory and annual legislation of any mandatory records of status and investigations of equipment. - Please note that this document is only published to showcase my work - any use, distribution, copying or any other sort of media use is prohibited as the contents are owned by Siemens and the equipment is covered by patents and the report is covered by copyrights.

Unveiling the Secrets How Does Generative AI Work.pdfSam H
At its core, generative artificial intelligence relies on the concept of generative models, which serve as engines that churn out entirely new data resembling their training data. It is like a sculptor who has studied so many forms found in nature and then uses this knowledge to create sculptures from his imagination that have never been seen before anywhere else. If taken to cyberspace, gans work almost the same way.

Putting the SPARK into Virtual Training.pptxCynthia Clay
This 60-minute webinar, sponsored by Adobe, was delivered for the Training Mag Network. It explored the five elements of SPARK: Storytelling, Purpose, Action, Relationships, and Kudos. Knowing how to tell a well-structured story is key to building long-term memory. Stating a clear purpose that doesn't take away from the discovery learning process is critical. Ensuring that people move from theory to practical application is imperative. Creating strong social learning is the key to commitment and engagement. Validating and affirming participants' comments is the way to create a positive learning environment.
