The figures underneath the solid lines are in millimeters, the ones above the line are in inches. The X.XXX - X.XXX is a range, to account for variations in manufacturing. So for example, the width shown on the plan view of the chip (top) is given as 0.220 - 0.310 inches. This means that the actual value could be anything in that range. Some chips might be ...

A similar graph from a another discipline is the following Basically you will need to plot for each test (which I assume had a different d/S), the values of your experiment. So for each d/S you calculated different values of the convective heat coefficient at different air speeds. So you need to plot 10 different graphs.

Fiber cables have higher data transfer speed not because light travels faster in a fiber than electromagnetic waves in a copper wire, but because they can be modulated by signals having far higher frequencies than can be managed in the case of copper wires.

Two possibilities come to mind: One, the assumptions / theory / model is not describing / modelling the situation correctly, Or, Two, the source data is incorrect / has an error at those locations - perhaps the sensors are not mounted the same or the mounting points have been damaged / moved or the calibration for each sensor has drifted.

Based on the discussion in comments, you probably want to use a bar chart combined with a line for the error. Have a look at Create a combination chart for more details. In your case, and using dummy data, it would probably look something like this: Data in Excel Resulting combination graph

What you are asking is not trivial. As PeteW said, you probably will find something in DSP, although this might be a bit too basic for them. The problem with sound measurements is that the amplitude can be significantly different. One way is that you can differentiate is though frequency. So what I'd do is: break up the signal is a fixed time period (more ...

The starting point is to recognize that your calibrated sensor is first used to calibrate your light source, and then your calibrated light source is used to measure the response of your second detector. Assume that the calibrated sensor comes with a statement of its relative linearity $\Delta m_o / m_o$. This is a statement saying that the response from the ...

Apart from Jeffrey's excellent analysis I'd like to point out that, assuming that sensor A is calibrated and has a linear response, it seems like sensor has a non linear response. Figure 1: Excel graph of available data Figure 2: Residuals plot indicating a systematic not linear response of sensor B (assuming Sensor A is calibrated and has a linear ...

Plot dat_A against dat_B. Fit a curve to it (linear would be the simplest). Use the curve as a lookup table to lookup sensor A equivalent value when measurement from sensor B is available. The curve fit will also tell you the input ranges where the fit is good and where the fit is bad. This can be used to gauge the uncertainty of the looked up value. Ensure ...

Per @Dan's suggestion, I googled "nomography" and found an article titled "The Lost Art of Nomography" by Ron Doerfler, published in the UMAP Journal 30.4 (2009). The article describes a compound-nomograph, which is pretty much what I need. Here is a screen shot of such a device, taken from the article: The image shows a nomograph for three independent ...

Having done this before when I was in college on the solar car team, designing and building cars for Sunrayce '97 and '99, I'll tell you that you're on the right track, but you need to start with a simpler dataset. Start with analyzing something like a basic grade, something that you can check using hand calculations (they still teach that stuff, right?) ...

Yup. You can test your 2's compliment math on a calculator that displays binary. For $n$-bit numbers, you negate the number by subtracting it from (positive) $2^n$. So -17, in 2's compliment, is 100000000 - 00010001 = 11101111. Or subtract 17 from 256, and then display the result in binary.

Search for daily maximum and minimum temperatures for your local region. If there is a river nearby, search for river level or river gauge height. If it rains, search for annual rainfall in your region.

The keyboard contains many switches (100 in my keyboard at this moment) and the simplest solution for a keyboard assembly that contains no decoding circuitry would be for each switch to have its own line going to the motherboard, plus one common ground. This is inefficient. The simplest scheme to minimize the burden of all those wires in the interconnect ...

Figure 1. Making a scatter-plot on Google Sheets and adding in a trend line suggests that you've got a good chance. A quick search shows many articles on find the equation but it would be simple enough to create an extra trend line of the form y = mx + c and adjust the parameters to get a match to the data trend line.

Niels Nielsen's answer is correct. Just to provide some calculations as to actual propagation speeds (not signal bandwidth): Typical optical fibers have $n\approxeq 1.5$ , so the propagation speed is $\frac{c}{1.5}$ , or roughly 2E8 m/s . This is the field, or photon, speed. Using the formula from Wikipedia, the speed of electromagnetic waves in a good ...

If the data is over a 24h period and you have the times of these "other" sources causing the outliers then you can exclude those times from the general analysis. Deleting those time entries is one possibility, setting a constraint to exclude those, depending on how the analysis software works is another. But you should evaluate how that affects the ...

Are you asking how a scanning LIDAR physically works? Or just the format in which it outputs data? I feel that you're overthinking something. Because the raw data that is obtained by a LIDAR is the angle at which the beam is pointing and the distance that was measured when pointing in that direction. It is just a rangefinder at heart after all and can only ...

As stated by @NMech, I would suggest using a sniffer. I am assuming your connections are something like the following. I would use wireshark which a very popular open source tool used by network engineers. There is plenty of online support. Below is a screen capture of data traffic. Reference: How to Capture an IPDS Trace in AS400/OS400 Environments (2011)...

Since I don't know anything about the Siemems MP377 (what does it do and how its connected to the printer e.g. through a hub or with a direct crosslink cable), one way i could go is using a sniffer (See topology in the following image ). That way, you make sure that the data sent to the printer remain the same, and you get a copy of the data to another PC. ...

If the holes are small enough and you don't care about spacing measurements, you could use what are called pin gauges. These will obviously not work on non-circular holes (irregular?) These are available in sets of various ranges. The precision is quite good, often measured in tenths of a thousandths of an inch. If that is excessive in terms of precision ...

Maybe you should check out tribology. There is such thing as specific wear rate, k, for example, which is given for a pair of materials in dynamic contact. Say steel over steel has very low coefficient, even better than PTFE over steel, for example.

Accelerometers are capable of measuring the acceleration they experience relative to free-fall. Accelerometers are used to measure the upwards acceleration that counters gravity when at rest, its a hoax that it measures the acceleration due to gravity. This acceleration is measured as 1 g (g = 9.8 m/s2) on the z-axis, when both pitch and ...

The fundamental problem here is that you've got a bunch of numeric values which are not in engineering/scientific notation, so you have to make up some arbitrary guesses as to how many sig figs really are there. Let's look at one of your values: 34745 . Where did it come from? If it's, say the reading on a digital display for a widget whose operating ...

A broadcast operation involves flashing the data just like a notice board, and whoever requires the data, can read it from the node or terminal broadcasting it. Hence, any node which comes in the radio range of the node broadcasting the data, can see the information or data. In case of RF transceiver, if the master is broadcasting, all slaves in its radio ...

See NASA's computer program CEA (Chemical Equilibrium with Applications). From this site you can download an application to perform calculations. This application contains a text file called trans.inp with coefficients, $A$ through $D$, for an empirical dynamic viscosity equation: $$\ln\eta=A\ln T+\frac{B}{T}+\frac{C}{T^2}+D$$ and for thermal conductivity: $...

Andre, I assume you've got an answer to this question by now; please tell us how you solved it! – NauticalMile Unfortunately I didn't found any information regarding the high temperature values for the viscosity nor the conductivity for those gases. I used a very crude method to get around the issue. Basically, I interpolated the available data using some ...

SDR is normally done with I (in-phase) and Q (quadrature) channels. You can think of them as the two components of a complex number. These allow you to preserve the phase information through your signal processing chain, which is important for some kinds of modulation. For more information about what this entails, you should browse our related DSP.SE site.

The equation you included in your question only considers horizontal distances (x and y). You need to use slope distances (three dimensional distances: x, y and z) as these will be the true distances travelled by the vehicle. Assuming the distances in your data spreadsheet are slope lengths, sum all the lengths to give the total slope distance between the ...

Not sure if this approach is in the format you need, but it might help. The work required to go uphill by a height $y$ is $$W=mgy$$ where $m$ is mass and $g$ is gravitational acceleration. Assuming mass and gravity are constant, we can differentiate this equation with respect to time to get: $$\dot{W}=mg \frac{dy}{dt}$$ we can also use the chain rule ...
