Questions related to Prototyping
Reconfigurable intelligent surfaces (RISs) have promising coverage and data rate gains for wireless communication systems in 5G and beyond. Prior work has focused on signal processing part more and prototype design part less. How to design IRS efficiently to improve QoS of 6G communication? Which tool is best suited for design and simulation of surface, CST Microwave or Ansys HFSS or both of them? How to simulate the unit cell and how to simulate array?
For district, city or urban scale building energy modeling, we normally only have the building footprint (polygon boundary), their average height, and the number of stories. which method do you use to create the 3D geometry and zoning for different building types based on those data? Or which method do you think is the best for urban building energy modeling? Or do you use any other methods?
1. Use prototype building (typically rectangular) with same floor area, orientation and aspect ratio?
2. Create one zone per floor?
3. Separate the internal zones with the perimeter zones (e.g., 15 ft/ 5 m width for the perimeter zones)?
It must have high thermal conductivity even if it is not electrically conductive. However, it should had high stiffness value so that it will not warping
I'm starting to model an urban simulation and I'm having a bit of a dilemma regarding what language to use. Have some experience in Netlogo and I'm starting to make a shift towards Repast, GAMA or MESA (geo-mesa), because it is recommended for large scale simulations.
Have been reading papers about which tool to use, but I need someone working on simulations to help me out.
Still, I have questions because:
1- The user base of MESA is scarce and i feel that dealing with issues will be dificult
2- So far i have only seen and read about limited research done in MESA. Specially, dealing with road network integrations. (move an agent along a network)
3- It seems that Netlogo is good for prototype, will not handle big data projects
Thanks in advance, and any pointers to courses or moocs would be great.
I just completed my RFID tag antenna design and simulation with operating frequency 925MHz. Followed by prototyping recently.
The simulation is done with the tag attached on the conformal platform with the polypropylene(PP) material.
However, the simulation S11 frequency band is about 880 - 920MHz for less than -10dB.
What frequency range should I set on the network analyzer to measure the prototype impedance and S11.
Thank you for the help.
As far as I know (please correct me if I am wrong), ICs were invented before the invention of MOSFET structure. Jack kilby invented monolithic ICs in 1958 and in early 1959 Robert Noyce invented hybrid ICs.
Did those inventions use BJTs?
I have not found any correct information regarding this.
May anyone please help to reach deeper information about the component type of early IC prototypes?
how does the mental cognition go?

Through multiple empirical studies, I have collected user needs for an ICT intervention. During this study, I intend to design a prototype and then evaluate the prototype to check whether user needs are captured in the proposed design.
What is the most suitable approach? Quantitative, Qualitative or mixed?
Are we evaluating the features of the prototype or evaluate the user requirements?
I have designed an Digital Artifact (Web based solution) and now looking for a best possible ways to evaluate the prototype. Is it necessary to evaluate each and every 'Design Features/Requirements' or is it will alright to check by grouping the common 'Design Features/Requirements' ? (Looking for more information than just specifying questionnaire, interviews, surveys, etc.)
I need to know the necessary design calculations to conduct and how to go about it
Hey, Could you please spare 10 minutes and watch the related video of my prototype and answer the required questions?
I really appreciate your time.
In the last week, one of my journal got rejected from International Journal of Human-Computer Interaction. Now I want to resubmit it in another journal. If anybody suggest me a Q2 or Q3 journals. The title and abstract of the journal is given below:
Title: Dynamic User Experience for efficiency enhancement based on facial expressions
Abstract: The main motive of Human-Computer Interaction is to make human comfortable while working with interactive computing device so that it can increase human efficiency and release the human trouble and saves humans’ time. In this paper, we recognize the face first then change the UI automatically based on his facial expression. Some of our personas also proposed the similar idea of building a system that would play music based on their facial expression. These scenarios gave us the idea of making an integrated system of dynamic user experience based on facial expression. So, we started to collect the data of our paper-based on questionnaires and interview approaches. Then made some low fidelity prototype during requirement gathering phase. We also made some high-fidelity prototypes using Axure RP to show the stakeholders the likely output of this paper. In the new phase, we have used the software engineering model and then implemented our code in visual studio with live server extension. Then we have followed the cognitive walkthrough model as our evaluation method. During the evaluation, our stakeholders need not have provided any input manually and it was easy to earn to use the system. We found that there should be a high-speed internet connection and we have to use VPN to handle some issues. The user was not feeling fatigued or discomfort at all because it is very easy to learn. Anyone can use it and who wants to use it just need to be in front of the camera that’s it. So, the user was very much comfortable and happy to use our system.
Thanks in advance.
I am interested in this research field. I have the prototype of my microfluidic chips, but I am having a hard time finding literature that says exactly how they incubate their chips (with syringe pumps and all) in the incubator? How is it done?
I want to culture cells in the channels in the chip, with a constant flowing media, but is it feasible to put the whole syringe pump into the incubator as well? TIA
My colleagues and I intend to implement a real-time controller. So that a simple real first-order system is controlled by a controller designed in MATLAB/Simulink environment (Rapid Control Prototyping). We would be grateful if you could help with the following:
Is this possible with the help of dSPACE devices? And in that case, with what tools? For example, is the DS1202 MicroLab suitable by itself?
In general, what configuration is proposed for such a system in real-time modeling? (In the academic field)
We would also be grateful if you could suggest an example (project, article, book, schematics, etc.) in this regard. Unfortunately, with so much searching, most of what I found was just PWM generating for power electronic converters.
We are also interested in any advice and experience you have had in this field.
Thanks & Regards.
My students are using the following software in developing their prototypes for the Software Engineering course projects:
- JustInMind.com (Interesting, can develop mobile app, but needs a learning time)
- Wix.com (Easy to develop, but limited to e-commerce apps), and
- Visual Studio (Not easy for the new learners, but can the prototype be promoted to a real app)
- I am also investigating the wireframe of Visual Paradigm.
Can you suggest to me more interesting and easy to use prototyping tools?

I am working on a project on designing and testing new materials and different structure(3D-infill) configurations as prototypes for the mid-sole of a running shoe.
I was wondering about the functional properties that would be required from the mid-sole of a shoe to optimize its performance.
Any leads regarding mechanical/functional properties of running shoes, midsoles or regarding mechanical testing of midsoles would be very helpful.
Where can I get the code for K prototype algorithm for mixed attributes? Has anyone implemented it in any language?
Currently I am doing my final year project and I need to simulate an automated lubricant dispenser for a CNC Tank (the tank which located behind the machine). Not to be confuse, I am not modding or changing the lubricant system in the machine but I am trying to find an automated way to ensure that no manual labor needed to refill the tank weekly.
The aim of my research is to simulate a working dispensing system that can refill the tank automatically and monitor the amount of lubricant use during each refill.
Does anyone know a software that enable me to simulate the project? or should I just make a mini prototype of the system using arduino?
If your research goal is to develop a conceptual prototype, model, an app, or an algorithm, would that be qualitative or quantitative research ?

I am trying to carry out numerical analysis of reinforced earth walls using the software FLAC 2D. I am validating my numerical model with the results of a centrifuge test carried out under 50g centrifuge acceleration. I wanted to know if I should carry out the analysis in model scale or in prototype scale for better results? When I am carrying out the analysis in model scale and an acceleration history (sine wave amplitude 0.2g frequency 2 Hz time 12.5 s in prototype scale) with amplitude 10g frequency 100 Hz time 0.25 s in model scale, I am getting results that not at all matches with the experimental results. I am attaching the paper in which experiment was reported for reference.
I am interested in measuring the underlying inflammation associated with viral infections (corona virus or influenza) to test the hypothesis that a inflammation-associated severity index might have clinical utility in treating patients.

We are developing a Automated Guided Vehicle(AGV) for industries. We have developed a prototype which is working very well using embedded arduino board. Now we want to mass produce this model for the market. We are not sure which Micro-controller board to use other than development boards and PLCs. We don't want to use PLCs since they are expensive and will increase the cost of our product. Some people told the same embedded arduino mega can be used for production model also with proper protection from dust,humidity etc which are common in industries. Yet we are not sure so we looking for boards which we can use in our AGV. We also don't have in-house capability to develop the board on ourself. So can anyone suggest any company or product (specifically Micro-controller ) for us to use in industrial automation other than development boards

So i have a foam based temporary prototype of a component which i want to be 3d printed. I wanted to make a cad model of it via solidworks or catia but it is too complex to model. If I uses mimics i have to import images in format of DICON file format. I want to take images of the foam prototype and then want to do analysis of it. Also after getting the 3d model i want to make some edits in it and then want to do analysis of it. Please suggest me a way to do. It would be very helpful.
I am currently writing my thesis and is trying to analyse my data. We thought we could use a z-test but since our collected data is not normally distributed we are trying to find a new method to use. We collected data via a survey where the participants looked at prototype 1 and later answered questions in a 5-point Likert scale, before moving on to prototype 2 and answered the same questions for that one as well. We want to compare the two prototypes as well as look at them individually. The participants were a convenience sample and we got about 80 answers.
Does anyone have a suggestion on what kind of data analysis method we could use?
Any help is very welcome, thank you!
I want to file a patent for my prototype/method. The total cost on the fabrication of prototype was Rs. 250 only. What's the simplest way to file it and how much it will cost to me.
I need help on the best definition of FLOOD

In my survey, I presented the respondents with pictures of 2 products (new Vs prototypical) and ask them to rate their relative preference on a 7-point scale.
The measure question was:
For category 1, which product would you be more likely to choose?
1= definitely product A, 7= definitely product B
The design was 2 (product type: new/prototypical) x 3 (product category). Both were a within-subject design.
For a masters course, I am currently writing a small paper on organisations as a whole.
Explaining it in different categories, such as an essentialist, goal directed and prototypes.
For an additional requirement, I am required to find a counter-duck example of an organisation. In other words, I am attempting to find a social entity that acts as an organisation with a common goal but is not formally recognised as an organisation.
If it is still unclear, I can clarify further but in the mean time, thank you for any assistance.
My team and I have developed a prototype of an augmented reality mobile application for teaching primary school students human anatomy. We are going to do a usability testing and evaluation with the primary school students using FUN toolkit, and we are also going to conduct an expert review using heuristic evaluation and cognitive walkthrough. Furthermore, we also want the teachers to test the app, and to evaluate the usability in the context of their students' usage. However, the teachers are neither usability experts nor end-users so what is the most appropriate method for them regarding usability testing, survey design etc? Do you have any recommendations for usability testing methods, survey design/template etc.?
I want to see what everyone thinks about this and if you have some information that can be useful it would be nice. I'm trying to find some kind of advancement I can make in this aspect since it may be an optimal way to do it, and seeing everyone's point of view in this, its gonna be a huge help.
Hi, I'm trying to design a reduced scale model of a turbine tested with glycerol. The prototype idea is to install a turbine in tailings flux to recover a percentaje of energy from it.
The reduced scale model will test the turbine (reduced scale) functioning with glycerol, to simulate viscosity and density of the tailings. The porpose is to get the efficiency of the turbine functioning with tailings.
I have two main questions:
1. Which parameter should I match to scale the machine ? Reynolds, tip speed ratio?
2. How can I scale the viscosity? reynolds?
I feel I need more equations to develop the similarity between Q, RPM, Viscosity, density, etc.
Imagine an assembly line where objects are lined up and passing under a sensor.... The objects are smallish, about the size of a sugar cube, and randomly shaped. Some are cylindrical, some are squarish, some are round.
All the objects are metal and could be steel, aluminum, or brass, or some other metal or alloy.
I need a way to detect only the brass objects and pluck them from the rest of the objects.
Would an ultrasonic detector be able to do this?
Or wavelengths of light, high frequency sound?
I'm not looking for a complete solution, just an avenue that has promise that I can research and prototype.
Our lab is building a prototype for cell analysis. It is currently being tested by engineers in an R&D setting. I want to assay for cell death but do not want to use dangerous drugs to do this as I want to limit exposure of staff to drugs. Can anyone suggest a chemical to induce cell death - I was thinking of using hydrogen peroxide but am open to other suggestions. Thanks
So a little introduction, our group is making solid state devices (MRAM etc) but so far we have only work on proof of concept stage.

I need suggestions on the best type of support structure to be used for 3D printing Inconel 718 using Island strategy (5 x 5 mm). Will these structures affect the texture of the part produced? It would be great, if anyone could send the matlab file for generating the coordinates of the advanced support structures.
I am a new comer for the research of portable or wearable sensor for disease diagnose. If such sensor is integrated in smart phone, it will be promising. The current portable sensors are isolated from smart phone, but can be candidates for smart phone additives. Would you like to tell me about some companies, which already developed some portable sensors or detectors for health care.
Thank you very much!
I made a thermal neutron detector based on 10B layer that was made by PLD technique, and I use a silicon photodiode for detected the particles. In this way this was my project for my douctor degree and I finished him. I am writing a paper about it results that hope publish soon. And my idea is to use this prototype and made a dosimeter based on him. For this reason I am very interest in have more details about your project.

I've read a paper describing the modelling of a half-wave rectifier based on Schottky diode (Schottky model.jpg). The model is well-known, however, the author explains the scheme of such circuit and fabricates the prototype differently (please see two other figures). I do not understand why the diode's cathode is actually connected to ground? It is supposed to connected to the load as shown in the first image! Here is the description of the author: " Diode’s cathode is connected to the ground which locates at the position that magnetic field reaches its first valley to obtain maximum current in the circuit". Is there any mistake in these? Any advises are highly appreciated.
I expect to make a prototype at the size of 1" diameter disks. I expect to make the housings by 3D printing. The disks, by laser cutting spring steel, the rotor by machining brass or steel.
What is the best material for plating the housings, to reduce wear:
A: for pumping water?
B: for pumping crude oil?
C: for creating vacuum?
I am conducting research on the applicability of blockchain technology for electronic health records. Part of my objective is to create prototypes with blockchain technology. I would like to determine which blockchain technology/technologies are most suited for EHRs. It could be one blockchain technology or a combination of them. I was wondering if we could discuss some use cases/prototypes that would be worth it to explore with blockchain technology? I am also concerned with how I would proof the validity of a prototype?
