Hi Lloyd. Thanks for sharing the video. I'm trying to understand what goes in the models that you show in the context diagram (22:00). These are driver, truck configuration and Load weight models. Would you use physics equations in these models (e.g. for gearing loss)? Thanks again for sharing the video - is quite informative to get 'trained' on the subject :)
Hey Omer, The load weight model that we use is indeed physics based in the sense of looking at the acceleration characteristics of the truck and measuring the amount of energy that is consumed to produce that acceleration. We are not really arriving at an explicit weight in kg but rather a classification of whether the truck was light, medium, or heavy load using this approach. The Gearing Loss is also an equation that takes into account the drive train configuration of of the truck (e.g. transmission and differential) to assess how much extra fuel is being consumed at highway speeds. It is not uncommon to have a truck that is "setup" for city driving end up running lots of miles on the highway and wasting fuel because of its configuration vs. use. Let me know if that helps you understanding. -ll-
Hi Lloyd.. a Very informative presentation. What I liked the most is when you modelled the fuel economics and how digital twins could be used to address this problem. I am currently woking on using digital twins in power systems. I am wondering if you can recommend an open-source tool to use in building my digital twins. Sorry if this question was asked before, I did not read all comments.
Hey Tarerkuk ... I am glad you enjoyed the presentation. I do not have any specific suggestion on power systems other than you may want to check out the open source python simulation framework simpy.readthedocs.io/en/latest/ it may be a good starting point for your work if python is your preferred language. Also, microsofts azure digital twin framework is another choice for cloud based solutions azure.microsoft.com/en-us/products/digital-twins/... Best of luck with your pursuits! Lloyd
Hey Sola...check out my reply to @SIDDHI CHIKODE below. I think the open robotics framework is a good potential for you too! Good luck with your project.
Hi Lloyd , Your session is very informative , I want to build digital twin for specific disease let say cancer or Glaucoma ..which tool/simulator do you recommend to begin with?
Hey Ashutosh ... the key to assessing disease is to generate a viable model for the body or parts of the body that will be germane to understanding the differences between a healthy and unhealthy state. Then through this modeling of the body, we can begin to pull apart what happens under disease conditions to more effectively treat or prevent the disease. For example, this paper pubmed.ncbi.nlm.nih.gov/19044244/ may be a helpful reference for building such a model for the eye. Good luck with your pursuit of building digital twins for medical applications!
it occurs to me that most (all?) modern vehicles, or at least their engines are controlled by a computer and that this network of sensors comes out to a "diagnostic socket" where a repairman/maintenance engineer will plug in another computer to be able to see what is working and what is not. Would it not be a good idea (Pehaps it is already being done) to connect this socket to the cloud to give continuous data on how the vehicle is behaving?
You are correct, Anthony, there are many applications that would benefit from access to the diagnostic data that is published by these trucks (and cars). One important consideration is the cost and bandwidth of data from the truck/car. There is almost always a need to process data on the edge (within the vehicle) and to heavily compress the data to deal with cellular limitations.
Great presentation Lloyd. I'm trying to research in digital twins to show interior or exterior as built utilities with drone or Lidar data for CAMPUS facilities project but being new to this i am confused to use a opensource software for development of digital twin and its application for the optimizations. It would be very kind if you suggest the way to start developing a digital twin with sfm datas.
Hey @sabinpandey5385 ... this sounds like a cool idea. What are you shooting to do with the utility survey? In particular, think about what you are trying to optimize. I often ask, "what am I trying to get more of or less of by performing my optimization. For example, in this video, the point of the digital twin is to provide real time feedback to a driver to "use less" fuel. In your campus utility survey, what is your quest? Let me know and we can zoom in on how to best proceed. Looking forward to your input...
@@whatcandatado thanks for the replay... i am thinking of developing digital twins which can help in better infrastructure management, maintenance, space planning, or optimizing utility usage. However, with drones and LiDAR data there also requires a GIS data of utility. Do you think this would be a good idea showing electric lines, water or sewerage.
Let's say you want to monitor utility usage and provide feedback on what actions to take to reduce energy usage. How would the drone and LiDAR data be critical to providing that insight? I think there are likely applications with the drone and LiDAR imagery could be helpful in ongoing inspection but I am having a hard time coming up with the reason that the image data would be necessary for something like energy optimization.
@@whatcandatado true, I was thinking the application in wrong direction.. I guess wasted some time researching it.. can you suggest me way to show 3D models and sub surface utility data together by using digital twins? or how can I integrate subsurface data into 3D models of LIDAR , drones and create a model that keeps changing as I gather new data
@@sabinpandey5385 I recently came across this application of a Large Language Model (LLM) where the researchers can "ask questions of their spatial data" vis-www.cs.umass.edu/3dllm/ I am not sure this is in line with the sort of application you are imagining, but I would contend that a system that processed drone (LiDAR) point clouds and allowed users to prompt the system for items of interest. For example, Let's say I have a survey of all the outdoor utilities of a specific campus and then prompt the model to highlight all the shutoff valves for the water system. I'm making things up here to explore the possibility. The other key thing to consider is to ask if the utilities potentially need repair based on some image analysis. This would be a fairly involved project. I don't have a lot of experience marrying LiDAR point clouds with GIS data, but I recall this ESRI reference ruclips.net/video/JxdX3kZCJmY/видео.html being a pretty good introduction. I wish you the best of luck with your project. Let me know how things come together.
Hi Lloyd, thank you for a very informative talk. I want to use digital twins in additive manufacturing (3D printing). I am wondering if you recommend me an open-source tool to use in building digital-twins.
@@whatcandatado Yes!. Currently, I am working on controlling and monitoring of 3D printing. I guess that digital twin is a best candidate to virtually analysis the 3D printing mechanism. I would be happy If I could find any possible way to build digital twin of the actual 3D printer.

Hi Lloyd, I am beginner exploring with Digital Twin. I want to build the digital Twin of a forest can you suggest me any open source or any other platform where I can do so?
Hey Anusua... this sounds like a really terrific project possibility. I would check out the US Forestry Forest Vegetation Simulator github.com/USDAForestService/ForestVegetationSimulator.

Oops ... I missed your comment from a long time ago. Your interest in DT for solar system is a good one. This could go in many directions and a result could get quite complex. If you think of the DT being comprised on a model or models and a source of real-world data to drive your model(s), I would start there with your quest. What are you interested in modeling about the solar system and what data can you get your hands on to potentially facilitate that modeling. The key step in your planning is to make sure you have a clear articulation of your objective. What are you trying to illuminate for the purpose of optimizing or understanding what will happen under certain circumstances. One simulation that scientist likely employ is what will happen under certain circumstances when an asteroid enters earths atmosphere or what would happen if a satellite dropped out of orbit. Both of these scenarios are best served with a physics based model of the system you are exploring.
Hello sir, can you help me with working on digital twin of robotic arm? It will be great if you could talk about which simulation software to be use and how to proceed with the 3D working model of the robotic arm?
