For example, camera $50..$100. It is an excellent resource for those who know about it. Klein notes that across the studies he’s done, three factors repeatedly come into play when Marines operate under uncertainty — factors that he argues generalise well beyond the battlefield: In Chapter 8, Klein deals with all three factors. 5. Many equipment manufacturer’s regularly publish white papers about their products and their research. Required fields are marked *. 15. The Guide to the Expression of Uncertainty in Measurement (GUM)is the de facto standard for evalua… Loads that are considered in design are predicted loads likely to act on a particular type of structure. We then report that the measured amount is approximately 19.9 ml. It is stressed that sample preparation is usually the biggest contributor to measurement uncertainty. Measure journal. These are some the references that I routinely use when calculating uncertainty. Now that you have 15 new resources to find significant contributors to uncertainty in measurement, I am sure that you would like to access them quickly next time you calculate uncertainty. You could waste hours of your life researching sources of measurement uncertainty. What’s going on? Klein’s work does not apply to ‘irregular domains’ like stock picking, venture capital, and political forecasting, where expertise is difficult and intuition should not be trusted. However, if you have access to a college or university library, you can get access to Metrologia online for free. One the most difficult things about calculating uncertainty in measurement is finding sources of uncertainty. Updates weekly. The Problem. This is the uncertainty regarding the turning of cash disbursement related to the firm’s major capital expenditure and construction firms are notorious for filing late progress reports and then expecting immediate payment. Not every publication in this journal is about measurement uncertainty, so you may have to do a little research to find what you are looking for. Analysis of gold alloys by flame-AAS: High. I have, and I am sure that you have too. He lists the many, many tactics available for handling uncertainty, tracked over a few years in his research.

Textbooks Think about the kinds of decisions that you face at work: The problem with reading up on solutions for uncertainty, however, is that the popular methods we read about very often come from the realm of finance, where professionals have had to deal with uncertainty for far longer and at a much larger scale than is usually the case for the individual career. Below, you will find a list of reference material and websites that will help you find different types of measurement errors and contributors to uncertainty faster. Most of them are related to mass and scale calibrations. Examples of Using Means, Forgetting Scatter • The Humble equation is widely used for calculating water saturation for sandstone in estimating oil reserves. Finally he includes the Budner scale (Budner, 1962), which gives you a method to assess your personal approach towards uncertainty. Conference Papers Instead of just throwing the CD in a drawer to never look at it again, try reading through some the papers. This uncertainty stems from different sources, including repeatability, calibration and the environment. Inside some of their articles, you will find information related to measurement uncertainty, which could help you find new contributors for your uncertainty budgets. You may be familiar with their “Good Measurement Practice Guides.”. Model uncertainty describes indeterminacy stemming from the models’ structure and inputs, and source uncertainty describes disagreement between how expert sources utilize models and interpret their output. But it is an approach to dealing with uncertainty, I’ll grant you that. Richard is a systems engineer who has laboratory management and quality control experience in the Metrology industry. Uncertainty in changes in long-term average river discharge decomposed into its main sources (GCMs, HMs and RCPs) for the high flows (Q10, top), mean flows (Q50, middle) and low flows (Q90, bottom). Learn how to estimate uncertainty for ISO/IEC 17025 accreditation.Click here to learn more. However, there are internal reports for length and volume too. For example, Patton and Timmermann (2010) study disagreement among professional forecasters, but do not relate disagreement to measures of uncertainty, while Lahiri and Sheng (2010) consider the relation- ship of aggregate uncertainty and disagreement over the business cycle, yet they do not distinguish between risk and uncertainty. Typically, the best places to look for sources of uncertainty and error are in the following sections; How might that even work? • Specification He closes that section with: This, too, is left as a literal exercise for the reader. Bookmark the links to these websites, After all, according to the author … With this information, you should be able to easily find new uncertainty contributors for your measurement functions.

Klein notes that across the studies he’s done, three factors repeatedly come into play when Marines operate under uncertainty — factors that he argues generalise well beyond the battlefield: 1. Cal Lab Magazine is another periodical resource that you can use to find sources that contribute to measurement uncertainty. Your email address will not be published. 2. This list of resources would not be complete if I left them out. As a base line, I think that every calibration laboratory should have at least a Physics and Chemistry textbook in their library. 2 A paradigmatic example is the classic two-urn Ellsberg experiment where the two urns identify distinct sources that differ in the stochastic nature of the uncertainty faced. The word uncertainty is rather badly defined. By taking stock of the tactics that are available, you might get some ideas about how to get what you want. Examples of sources of uncertainty in our field are the measurement of volumes, weighing, reaction temperature, purity of reagents, and value assigned to the calibrator. You will still have to dedicate time and effort to find sources of measurement uncertainty. It is only available to NCSLi members. There's an element of uncertainty in our plans. NIST Journal of Research We may call all of them by the same name, but we should not treat them like they are the same thing. For the third factor, Klein recommends that you rate yourself on the Budner Scale to gain an idea of your personal tolerance for uncertainty. Each time you find new resource or guide related to measurement uncertainty and your measurement functions, save it! Recently, however, I feel like I’ve gained a better understanding of this approach after I finished The Outsiders by William Thorndike. Uncertainties to be considered in structural design may be because of loads, materials, member imperfections. The answer is that there are 12 broad categories. I’m not knocking on such methods — they are incredibly useful if you have to grapple with uncertainty in an irregular domain in your career. The quote that struck me the most came from legendary CEO Henry Singleton, who said (in reference to time management): “I know a lot of people have very strong and definite plans that they’ve worked out on all kinds of things, but we’re subject to a tremendous number of outside influences and the vast majority of them cannot be predicted. Have you attended any conferences lately? Better yet, most conferences will give you access to all the papers on a CD. To find the uncertainty of a measurement result, we must first estimate the contribution from each source and then calculate the combined uncertainty. Additionally, there are many popular specialized textbooks, like Traceable Temperatures, that can be quite expensive (e.g $200 to $400). The information that you may find can be extremely helpful for your uncertainty analysis. This makes the EURAMET website a great resource to bookmark. And many of them are intuitive to us. concerning the distribution functions referred to above, and the sources of information for the estimation of component uncertainty values, e.g. The first is the choice of algorithm. When you begin to identify sources of measurement uncertainty, you should start by … Another National Metrology Institute (NMI) that publishes great content for estimating measurement uncertainty is the Measurement Standards Laboratory (MSL) of New Zealand. Such methods include actively adjusting for one’s cognitive biases, updating beliefs using a Bayesian method, and calibrating one’s beliefs by considering the big questions. 13. When reviewing the specifications, you will typically find details on the operating capabilities and accuracy of the equipment functions. Richard holds a Masters degree in Engineering from Old Dominion University in Norfolk, VA. Make sure to check out their website next time you calculate uncertainty.

To his knowledge, the list is exhaustive. Abraham Lincoln may have phrased it best; “Give me six hours to chop down a tree and I will spend the first four sharpening the axe.”. I hope this helps you as it much as it has helped me. Another source of uncertainty is vagueness, which arises whenever a concept provides for the possibility of borderline cases. If so, you should know that speakers come from all over to present their papers. Inside this magazine, you can regularly find great articles related to calibration methods and uncertainty analysis. • Noise Equipment Manuals 10. Best of all, it is free to the public. In line with the literature, a source is a collection of contingencies that correspond to the same “mechanism” of uncertainty; different sources correspond to different domains of uncertainty. White Papers & Guides My previous article introduced the idea that all measurements have uncertainty. Datasheets are great places to find equipment specifications and sources of measurement uncertainty. Make sure you [ninja_forms_modal_form id=89 text_link=’download this cheatsheet’] so you can easily access these reference materials. Trust me, create a digital archive! The reason that you should include these uncertainty sources each time is because they typically influence every measurement that you will ever make. Furthermore, try searching for textbooks related to your measurement discipline. Klein doesn’t make explicit recommendations for one tactic or another, after all — he merely documents what people do when faced with uncertainty. • Calibration/Performance Test Instructions.

I promise that it will save you a lot of time and effort. I'm sharing everything I know about Measurement Uncertainty! If I were breakdown the process of how to calculate uncertainty, it would look like this; Identifying sources of uncertainty in measurement and determining their magnitude of influence requires nearly 75% of your time. So, make sure that you look for white papers and guides. There are two main sources of uncertainty: data uncertainty (also known as aleatoric uncertainty) and knowledge uncertainty (also known as epistemic uncertainty). Five different implicit precipitation-type algorithms were applied to a collection of observed soundings that correspond to surface observations of SN, RA, IP, and FZRA. You will thank me later. There are three factors that go into dealing with uncertainty: the source of the uncertainty, the tactics available for dealing with the uncertainty, and the decision-maker’s own personal tolerance of uncertainty. After college, most people tend to get rid of their textbooks, so you may be able to find them online for cheap. Taylor and C.E. The commission's report has dispelled much of the uncertainty that has enshrouded the industry. The effects of two sources of uncertainty on the correct determination of precipitation type were considered. 14. 3. However, every issue is archived and available online. Connect with Richard on LinkedIn. This is easy to say, but usually difficult to do: often, we attempt to resolve the latter scenario with a search for more information — perhaps to avoid admitting to ourselves that we can’t interpret what we have at hand. I should note that this elucidation of sources and techniques aren’t enough to make you proficient. BIPM Key Comparison Database Additionally, you can access it both in print and online. That involves actually putting the methods I’ve summarised here to practice. If you organize your files and folders by measurement function, it will make it easier to find the right file when you need it.

It is a process that can require you to conduct hours of research.Seriously! So my idea is to stay flexible (…) My only plan is to keep coming to work … I like to steer the boat each day rather than plan ahead way into the future.”. (Variability and uncertainty!) Uncertainty due to projections of human behavior (e.g., future consumption patterns, or technological change), which is distinct from uncertainty due to “natural” sources (e.g., climate sensitivity, chaos) B ox — Examples of Sources of Uncertainty (from Moss and Schneider, 2000). What did it mean to embrace uncertainty as a competitive advantage? 8. 11. So, to get a subscription, you will need to become an NCSLi member. Below is a list of the 6 most common sources of uncertainty in measurement. 9. Keep in mind that Singleton is immensely believable: to this day, both Buffett and Munger call him one of the best CEOs to have ever walked the earth. 2. For instance, responding to a lack of information is different from dealing with information you can’t interpret. 1. • Operating Instructions When you want to find equipment specifications quickly, the best place to look is manufacturer’s datasheets. Thorndike investigates eight CEOs who excelled at capital allocation, and notes that most of them acted opportunistically, rather than sticking to the ideology of a long term plan. 4. Believe it or not, there are many textbooks out there that contain a lot of information related to your instrumentation and measurement functions. By now, you should know that NIST publishes a lot of content, and they have some more great reference materials for you to add to your library. While most of Klein’s work deals with the search for and development of tacit knowledge, I’ve found this chapter on uncertainty to be remarkably good as a piece of explicit knowledge. (If you’re new to this blog, note that Klein’s work is for decision-makers in ‘regular domains’ — that is, domains like fire-fighting, software engineering, operations, and management, where expertise is possible. He notes that the uncertainty in his domain of study really devolves to just five things. ISOBUDGETS is a consulting firm specializing in the analysis of uncertainty in measurement. Seriously!
