Questions related to Instrumentation
Candidate number one is a circular array of 12 triangular N40 neodymium magnet segments with three North Poles parallel to the axis and three self poles parallel to the axis configured as a halbach array with nearly no field adjacent a drive motor providing one quarter horsepower at up to 20,000 RPM. The estimated field strength is one Tesla. The estimated rotational speed is 250 RPM. The outer diameter of the magnet array is 4 in. The inner diameter of the magnet array is 2 in.
Candidate 2 is a commercial microwave induction cooktop with an input power rating of 1000 w or about 1 1/3 horsepower using a pancake coil operating at an estimated ultrasonic frequency of 25,000 Hertz with an estimated coil input power of 750 watts. The diameter of the coil is 9 in the inner diameter of the coil absent winding is 3 in. The magnetic field strength is unknown.
This is an active development and the candidate one main array remains unconstructed. Candidate one maybe marketed if an assembly process suitable for mass production is developed during research.
To compare candidate one with candidate too a ring cut from an aluminum beverage can makes a convenient one turn induction coil of extraordinarily lightweight which should provide a sensitive measurement of each candidates repulsion capacity.
The research has applicability to the design of magnetic hoverboards or magnetic pallets which would ride over aluminum sheet walkways to provide stable transport of delicate instrumentation or unstable materials such as explosives and volatile solvents.
Hi there! I am trying to quantify total inorganic phosphate from plant samples using a spectroscopy based techniques. I am facing issue with the standards. I have not tested the samples yet. For the first 3-4 standards, the coloration and absorption curves are linear but for standards with higher concentration the color is drastically reduced and curves drops rapidly. I independently repeated it thrice but got the same pattern. Do you have any suggestions to help troubleshoot this issue? Or, what protocol do you use? We are not interested in getting high resolution quantification data for phosphate amount in the samples, so we are looking for protocols which doesn't require sophisticated instrumentation. I have attached the protocol being followed in the attachment below.
I am measuring the tensile strength of thin (<1cm) dumbbell-shaped nanofiber membranes.
I have developed a custom tensile testing setup which primarily consists of:
1. A movable stage.
2. A load cell of appropriate force rating is attached to the moving stage.
3. A DC power supply to excite the load cell.
4. A digital multimeter connected to the DC power supply to measure the output voltages from the load cell.
5. A DSLR camera to record photos of the nanofiber membrane at regular intervals during the tensile testing to measure strain.
I am using a camera to record photos of the nanofiber membrane to calculate strain using a GUI based MATLAB program that tracks the edge of the moving end. I am using an optical method to measure strain because I cannot attach an extensometer to the nanofiber membranes as they are fragile and it won't be feasible.
The target of my experiments is to obtain voltage outputs from the digital multimeter every 1 sec and photos from the DSLR camera also every 1 sec with the measurements from the digital multimeter and the DSLR camera being in perfect sync.
I am currently triggering the digital multimeter using an Excel script provided by the manufacturer of the digital multimeter and I am using an intervalometer to trigger the DSLR camera. The problem is I am triggering both instruments manually and therefore the measured voltage and recorded photos are not in sync.
Can anyone please give me suggestions on how to sync both hardware which are from different manufacturers?
I am aware of most major threats to internal and external validity in group and quasi experimental research design such as maturation, history, testing, instrumentation, pretest-treatment interaction, statistic regression, mortality attrition, multiple test interactions, selection bias and the like but I am asking if there are other major threats and mitigation mechanism. List of threats and mitigation strategy....
I want to ask a question, about the loading protocol, which is very important, mostly in literature, 2 types of instrumental assemblie were used, 1) first one is to apply the axial load on the top of column and lateral load as well on column almost at distance 300cm from the lower pin of column.
2) second one is, to apply lateral load on beam,
So my question is which one instrumentation will be best and is the placement of strain gauges will be changed in both cases or will remain same.
I have been researching guided wave radar level instrumentation and I've run into an issue where vendors limit the solid rod and coaxial probes to 4 to 6 meters while wire rope probes can be used in lengths up to 75 meters. Based on my understanding of the technology involved (high-frequency material surface conduction) I would think that a coaxial probe would conduct the signal as well as or better than a wire rope. I have asked vendor representatives and the answers I received have been unsatisfying at best or technically inaccurate at worst. Can anyone give me a good, technical reason for this limitation?
Today, sensors are usually interpreted as devices which convert different sorts of quantities (e.g. pressure, light intensity, temperature, acceleration, humidity, etc.), into an electrical quantity (e.g. current, voltage, charge, resistance, capacitance, etc.), which make them useful to detect the states or changes of events of the real world in order to convey the information to the relevant electronic circuits (which perform the signal processing and computation tasks required for control, decision taking, data storage, etc.).
If we think in a simple way, we can assume that actuators work the opposite direction to avail an "action" interface between the signal processing circuits and the real world.
If the signal processing and computation becomes based on "light" signals instead of electrical signals, we may need to replace today's sensors and actuators with some others (and probably the sensor and actuator definitions will also be modified).
- Let's assume a case that we need to convert pressure to light: One can prefer the simplest (hybrid) approach, which is to use a pressure sensor and then an electrical-to-optical transducer (.e.g. an LED) for obtaining the required new type of sensor. However, instead of this indirect conversion, if a more efficient or faster direct pressure-to-light converter (new type of pressure sensor) is available, it might be more favorable. In near future, we may need to use such direct transducer devices for low-noise and/or high-speed realizations.
(The example may not be a proper one but I just needed to provide a scenario. If you can provide better examples, you are welcome)
Most probably there are research studies ongoing in these fields, but I am not familiar with them. I would like to know about your thoughts and/or your information about this issue.
I am writing a manuscript. The References, Instrumentation, Reagents and method, author and acknowledgement section etc are very much similar to some of the published articles and hence iThenticate shows plagiarism. I am confused should I exclude the portion during plagiarism checking. Is there any guideline in ACS, RSC, Elsevier on this matter?
I am trying to work on how variable characteristics can help to determine variable structure and pattern. I am half way into the work though.
Currently, I am working on a Rail-Structure-Interaction live research project using wireless sensors, which need to be compared with numerical analysis.
I am trying to find the amount of force transfer from rail to the sleeper, sleeper to deck and deck to Elastomeric bearing and then to the pier.
Any Idea or reference for Instrumentation will be of great help.
Thanks in advance.
When I am trying to implement a pressure sensor through instrumentation amplifier and then giving it's output to Arduino, I am getting garbage value due to noise, so how to eliminate it.
Nanotechnology (NT) is one of the advanced material science with which the development in materials and improvement in electronics. NT has made it possible to miniaturizing the things to fit in your pockets. There are several other products besides electronics and instrumentation etc.
For example, different colour coats which are dust proof, water proof. Now my Idea of asking this question is can we miniaturize AWS into a coin size? Can we make a material which can always make available the soil moisture to the crop plants? A material which we spray on the canopy or whole plant shielded from the pest and diseases? Will the soil become nutrient sufficient and providing the plants to sustain its life cycle without any problem? many more like that in my mind.
My SR785 Dynamic Signal Analyzer keeps rebooting after showing a "WaitFlag Error" in between measurements. I have been unable to find any mention of this error in the service/user manuals available on the SRS website (thinksrs.com). Any leads as to how to approach/troubleshoot this problem would be appreciated. Thanks!
Can you please tell me the ways to measure differential pressures across utility sides of the heat exchangers.
Unlike process side, the utility side pressure drops may not be measured. What can be done in such cases ? Are there indirect ways to measure it?
Hi, I'm a graduated Ph.D. trying to land a system engineer/instrumentation engineer position at an X-ray vendor company such as Rigaku and I have some questions about this:
1. How to standardize a measurement using either XRD or XRF so I know when the x-ray flux is wrong and I need to align it?
2. I did work as a XRD manager in my Ph.D. group so I gain some instrumentation knowledge here and there. However I wonder if there are any open source courses/literature/books for systematic education on theory, system configurations, source, detectors, etc.
Thanks for any help or advice in advance!
When purchasing an expensive chemical in a very small quantity (lower than I can accurately weigh with my instrumentation), I normally dissolve the whole package in a known quantity of water (measured by a pipette).
How reliable/accurate is the reported package size* for assessing the actual concentration that I got (assuming this package size is not included in the material's COA)?
Does it depend of the "Grade" or intended application of the chemical? (e.g., "analytical standard", "for molecular biology" etc).
*Package size normally reported by the manufacturer as "10mg", 25mg" etc. without decimal points or anything.
see for example this analytical standard: https://www.sigmaaldrich.com/catalog/product/sial/07442?lang=en®ion=IL
vs. a lower grade material:
I have a turbine flowmeter giving a frequency output (-5 : 5 V) with a wave shape as in the figure attached. This signal is fed to a Digital-to-analog converter to give a 4-20 mA signal to feed to my DAQ.
Now, I need to set the range for the converter (to know which frequency gives which current), to do this I should use a function generator, and I won't be able to produce the same shape as the output from the flow meter, so the question is:
Is the output signal (4-20 mA) dependent on the shape of the input wave or just the frequency?
The two plots in the attached figures illustrate spectra for copper-polyethylenimine (Cu-PEI) and copper-polyacrylic acid (Cu-PA2) complexes. In the spectrum for Cu+1.7 ppm PEI (first plot) there seems to be a characteristic peak at 263nm. Two studies suggest a characteristic peak at 275nm. Is there a reason for this deviation? The studies also mention a characteristic peak from 550nm-750nm in the visible region. In the second plot, I think there is a peak at 246 nm for spectra generated for Cu+B and Cu+11.8 ppm PA2. B is a solution that is expected to contain PA2. However, in both plots there seem to be no absorbance in the visible region. Is this due to low Cu/PEI/PA2 concentration?
I am more concerned about the design of the bath tank and the instrumentation involved in temperature maintenance including chiller, temperature controller, coil and/or heat ex changer . . .
I want to know about what is instrumentation system and how to develop a smart instrumentation system for small scale hydropower system to increase the efficiency of hydropower.
We have a keithley 2400 SMU in our lab but we can not control it through windows 10 64 bit. Labtracer 2.9 does not support win7 and over.Tektronix releases a software called kickstarter, however, it doesn't support REV C30 series. We want to control it and make special measurements.
I have recently learned the concept of override control in the p&id diagram. I have also learned some typical examples but whenever i come across a new complicated override control I find it difficult to interpret and identify the two selected and de selected controlls.
To continue the research specially laboratory based contribution, role of Instrumentation, Laboratory availability along with fund is very much crucial factors. Depending on each country economical conditions and Interest in research sectors , the Scientists and Researcher are obliged to maintained the compact work in where they are not satisfied on his/her own Research and its progress comparing with some developed as well as quality research addicted country. I think, these above mentioned factors highly affect the quality of research along with the researcher's interest. What do you think about your work environment and availability?
Are there any good general e-mail discussion lists for instrumentation people?
There are of course lists for HPLC, or spectroscopy, and several for mass spectrometry but are there any lists that cover multiple types of instruments where subscribers are faculty who teach instrumental analysis, or are in charge of instrumentation, or people like myself who are instrumentation support staff?
Does anyone have any sense of whether such a discussion list would even be of interest given how diverse the "instrumentation" field is?
To paraphrase that great Canadian philosopher, Red Green...An instrument guy makes his own luck, and frequently his own bandages.
I am looking for a best hardware solution to measure very low current values (pA -uA) without using any standard measuring devices. Now I came to know that with an instrumentation amplifier and a current sensing resistor I can measure low current ranges, but still I am not sure how successfull it would be. Is there any other analog circuits availabe to make this possible. Your suggetions would be much appreciated, thanks in advance.
ِِAlthough there are a lot of materials about gcc compiler that describe its internal structure, however RTL is not well documented.
Since gcc 4.5, we can write a gcc-plugin to extand gcc in order to perform additional works, e.g., analyzing, instrumentation, ... etc.
However, most of free plugins deal with GIMPLE representation (because it is easy). What about dealing with RTL? all the guys who presented some works about gcc plugin, have only focused on GIMPLE (they said, OK, we will not talk about RTL due to scope considerations, or because it is very complicated)!.
Sometimes, we need to add compiler passes at RTL code as a back-end. To perform that, we need to understand RTL. Unfortunately, gcc RTL is not well documented.
So in order to perform works at RTL level, for example, implementing a gcc plugin as a back-end to inject some instructions into RTL code, What should we do? Reading .h .c .cc gcc files? I think gcc internal manual is not enough to perform such plugin.
We are gonna built an experimental setup about the flow of supercritical CO2 under constant heat flux in stainless steel circular microtube (0.5 mm diameter and 300 mm length). It will be placed lots of T-type thermocouple along the tube to measure the wall and hence the bulk temperature. I would like to take your advice about the correct inserting types of thermocouples on the tube to take the better results. Regards,
In today's era of orthopaedics, PSI helps in performing the replacement surgery more accurately with reproducible results. The literature supports the usage of PSI with numerous benefits.
Market has numerous options of PSI - few being MRI based, while others CT based. What is your take on this technology and which one do you prefer, if any?
In the era of AI, to connect machine to machine and use of internet, for superior operations and performance, what role instrumentation and control engineers will play? Do they will be more needed people?
I am currently trying to figure out how i can use an Anasys Instruments NanoIR2 instrument to characterize my chitosan polymeric nanoparticles. Is this a possible instrumentation to use, or should i use something else? If i do use it, what is the best method of preparation of the nanoparticles to get optimum results on the instrument? Protocals and papers are welcome. Thank you!
I am working on the validation of a new LC-MS/MS assay for the determination of two steroids in serum and as a part of the validation of the method I am doing a patient correlation between our lab and some collaborators. Both labs use have the same LOQ, AMR we use the same transitions, similar gradient elution profiles and mobile phases. The difference between the two labs are the sample preparation steps and the LCMS instrumentation. Correlation of the results from analysis of cetrified reference standards is great (r2>0.9 and slope 1.1 for both compounds). When it comes to patient correlation, I detect two times higher concentration than our collaborator for one of the two compounds. Ion ratio remains steady and no peaks are found in the blanks. I re-injected the samples with longer gradient but the results remained the same. I double checked the calculations and everything is ok, no multipliers hidden anywhere. Why both labs get the same results for the reference standards and different results for real individual specimens?
i want to know how voltage scanning and frequency scanning in mass spectrometry instrumentation affect the results
I am having very good experience of growing SLG graphene with very high quality. First time, I have observed very weird RAMAN spectra from my SLG graphene consisting a series of peak starting from 1210, 1250, 1305, 1348, 1390, 1430, 1450, 1525, 1590, and 1700. Does anyone observed such kind of things. Is it really from graphene or can be instrumentation problem or from atmosphere. Even 2D band is lower then G-Band. This happen first time otherwise it always two or three times in magnitude from all of my samples.
I am using 632nm red laser for excitation.
I've used several methods to design a constant current source. Emitter bias circuit with transistor, Howland current source, opamp negative feedback with transformer coupling etc. Among them, a configuration using AD620 instrumentation IC (mentioned in its datasheet) gives the maximum constant output with a larger load range, almost upto 10 k.
Any comment on your experience regarding constant current source design?
The accuracy of hardware performance counters measurements is discussed widely in the literature. Using hardware performance counters, we can measure many types of micro-architecture events, such as cache hits and misses, load and store, and retired instructions. However, These measurements are still in question, how much are they accurate? As illustrated in many papers, with different device, results can vary. Some of these events, like store instructions, are deterministic events, i.e. the measurement results of store events do not change with re-execution of the program and capture the performance counter values. Retired instruction is not. Meaning that, if we measure a part of code, like a loop statement, we may get a different counter value from run to another one.
In https://pdfs.semanticscholar.org/340c/a872a54c4767c0e542dfa2ad63ccfb92c8d2.pdf, the author wrote:
"When deterministic counters do become available, they will be welcomed not only by those working on deterministic replay and simulator validators, but also by all users of performance counters."
By the way, can we use deterministic events like store events in tandem with retired instruction to introduce a deterministic user-defined event?
Any help will be appreciated

Need to learn any relevant rotating heat pipe/ heat transfer application in Automotive and sensors used for same.
what are the other rotating parts parameters using Non contact measurement /other methods using different Sensors.

I'm working with a small unbalanced panel dataset (N=24, T=30, Obs.=590). My goal is a typical one... to test hypothesized relationships between Xs and Y. When using a FE or RE framework, I've noticed that my errors are serially correlated. As a result, I'm thinking about making my model dynamic by adding a lag of the dependent variable as a regressor. I'm aware that doing so creates an endogeneity issue, leading to biased estimates. From what I've read, this bias diminishes as T increases.
Q1) Is T=30 large enough to ignore the endogeneity bias issue? Or do I need to address it via instrumentation?
Q2) More generally when are T and N considered "large/small"?
Q3) Can/should time fixed effects be used in a dynamic model?
Q4) How can I decide whether a single lag of the dependent variable enough? My dataset may be too small to support multiple lags but I'd still like to know.
Perhaps a dynamic model isn't the way to go. Alternatively, I could use first differencing or a time polynomial to alleviate nonstationarity issues.
Q5) How do I know which combination of these modeling techniques is most appropriate (dynamic methods, first-differencing, detrending, inclusion/exclusion of year dummies)?
Q6) At least one message board I found suggested that stationarity isn't a major concern when using panel data. I can't imagine how this could be true, as I think nonstationarity would lead to spurious results. Am I correct or am I missing something?
I've been reading message boards, online lecture notes, and academic papers for days but can't find practical answers to these questions.
If you can address ANY of these questions, I would greatly appreciate it. When doing so, please bear in mind that I'm looking for practical approaches and don't have the ability to understand highly technical/theoretical papers. Thank you!
I am modeling a dam with instrumentation. I've already fitted the settlements with mohr coulomb model.
There are several levels in which we have piezometers in and when I fit the lowest layer to the model, higher elevations' Pore Pressure tend to become higher and when I fit them, the lower layers show less pore Pressure than they should.
How can I fit all of the elevations or at least most of them?
FTIR spectra were generated for 0.1 M H2SO4 and 0.1 M H2SO4 which had a soaked polymeric membrane. At first, I thought the spectrum of the latter was a mirror image of the former, but that's not the case. Looking at the spectra at 860, 1010 and 1160 cm-1, supports this observation.
The absorption bands from 1310-1910 cm-1 and 3500-4000 cm-1 were caused by H2O molecules present in the branched polymer (30% PEI in H2O). The issue here is, the doublet at 2360 cm-1, which supposedly represents absorption by CO2 seems to be oriented at different directions for the two samples. What could be the possible phenomenon behind this effect?
I carried out an experiment aimed at confirming the presence of aspirin and to quantify the abundance of asprin using standard addition. And using HPLC instrumentation.
From the result, the chromatogram shows increase in the peak height as the concentration increases due to spiking and I thought this was a good result.
However the peak areas are not increasing, the increase then decrease, there is no steady increase .
Please what would be the reason. And how will this affect the error when peak area verse concentration graph is plotted.
I'm looking for instrumentation devices used in Metal & Mining industries, especially measurement and analyzers. It would also be helpful to understand the process for steel making.

I am interested in modern concepts/instrumentation/principles employed in the landslide early warning system
I'm trying to understand how John Dewey pragmatism (instrumentalism) influenced symbolic interactionism and its connection with Goffman Labelling Theory. Could anyone help? Thank you!
I saw a design in which people use a 0.2uV square wave input for AD8228 whose offset voltage is 50uV.
we have a batch reactor for CO2 capturing. A pressure sensor is into the reactor and monitor shows this pressure, also a pressure gauge is before the reactor inlet valve. when the inlet valve is open, the pressure that monitor shows is same with pressure gauge. In this manner when the reactor is evacuated, the monitor shows 0 for pressure. So the monitor shows realistic numbers for pressure. But when there is not any adsorbent in reactor and we fill the reactor with CO2 and then we close the inlet valve, the monitor shows a fast pressure drop at the beginning that it will diminish over time.
why monitor shows a pressure drop when no adsorbent is in the reactor (We checked the reactor and its connections, all of them are sealed).
We need to measure gas pressure in a reactor where temperature may reach up 1000°C maximum.
However providers surveyed just offer instrumentation that reach up 350°C.
Where or who can help us?
Does anyone have experience/recommendations as to which commercially available DIC systems are well suited for biomechanics studies at reasonable cost? We would be interested in strain measurements of cadaver soft/hard tissue and instrumentation.
Commercially available 3D printed medical devices include:

Implants (e.g., cranial plates or hip joints), and
External prostheses (e.g., hands).
Dear researchers, we need experimental results and data for Calculations of stopping powers and inelastic mean free paths for electrons in human tissue.including data, instrumentation, and methods to compare our theoretical results. Best regards.

If the basic ingredient of the universe is energy (ie even matter is basically energy E=Mc^2) and as em waves such as presently used. in modern communication, contains information , the idea of some em wave from space, which can create life without pre- conditions, as we know them now, seems feasible. It is interesting to speculate on this from different points of view.
I’ve worked and designed on the conventional tunnels such as NATM. But, in this time I’m beginning about excavation with TBM and I want know about the instrument in these tunnel. Is there any references about it? What are the difference between conventional method such as convergence meter, extensometer, and etc with the instrumentation which use in the mechanized tunnels?
Thanks in advance for sharing your experience!
I would like to measure sample in low-temperature (several 10 Kelvins) using THz TDS. Could anybody suggest a commercially available thermostat for that? A smaller one is better, as there is not large space (30 cm) between two antennas.
Thanks a lot!

I have spoken with Biometrics and they say the DataLINK may be connected direct to third party instrumentation via the R2000i or R2000iBNC analogue and digital output cable. Having look on their website at both of these, they need to be connect to a 3rd party AD board or data acquisition system or the BNC one is fitted with 8 BNC connectors for connection to a range of propriatary AD boards. Which of these cables is best and what AD Board do I need so sync with DataLINK EMG with Qualysis?
