Questions related to Graphs
It is well recognized that hypergraphs can be represented as factor graphs to some extent.
But something plagued me is that, when converted to a factor graph, how is the degree of a node in the factor graph calculated? For example, when a node i in a factor graph is connected to a factor node with cardinality 5 in a hypergraph, is the degree of node i considered as 5? Or is it regarded as 1?
Can anyone explain this for me? I appreciate it a lot. And thanks for your time.
I have performed 3-point bending on steel beam with 20*20mm square hollow section. I had obtained the Force-displacement graph for the experiment. I am trying to simulate this experiment in Abaqus Dynamic EXPLICIT.
For material model, I have used yield stress-plastic strain data. Element type used is C3D8R and three elements are used per thickness. The loading rate is increased to 1 m/s within the first 10 millisecond and thereafter it is maintained constant. Kinematic contact method is used to define the interaction between roller and beam. Also, considering the symmetry of the model, I modelled only quarter section ( force was multiplied by 4 times ). Symmetric boundary conditions were applied
The values for Force Displacement curve in simulation comes considerably lower than actual values. What could be the possible reasons for this ? How can I rectify this error?
A DMA graph of a thermoset polymer gives the storage modulus graph, loss modulus graph and a Tan (delta) graph. Tg of the polymer can be either Storage onset temperature or the Tan (delta) peak temperature in most cases.
In the case, the question is, how can we explain the relationship between half peak width (glass transition)of Tan(delta) and the network structure of the polymer. Can someone explain?

Dear all,
I conducted an oddball task to observe the p300 response, and I have a couple of questions:
1. I would like to inquire whether my ERP graph is meaningful.
2. Why does the brainwave response to the standard stimulus exceed that of the deviant sound?
3. I find these graphs rather complex. Could I receive some advice on how to create clearer ERP graphs? I created them using Matlab.
Your insights would be greatly appreciated!
Dear Technical Supporter,
My paper "Observations on graph invariants with the Lovasz ϑ-function" has been published in AIMS Mathematics, and I updated the PDF file and also added a doi link. However, Research Gate does not allow me to modify the status from Preprint to Article with the name of the journal. Could you help me please ?

My simulation has not yet reached the target number of steps. Here is my plot, MD trajectory,and my INCAR. (Sorry, the previous graph of the Gibbs free energy was incorrect. I have uploaded the new one here.)Thank you in advance for your assistance

I have read many papers on working of electrochemical sensing of materials. Somewhere researchers plot i(current) vs. v^1/2(square root of scan rate) and somewhere i(current) vs v(scan rate) to get a linear graph, so they can know whether a reaction is absorption or diffusion based.
My question is on what parameters we plot i vs. v or v^1/2 in a graph because there could be a possibility of having linear graphs with both v or v^1/2.
Thanks

Suppose:
- For natural number n, set A⊆Rn, set B⊆R, and (A,P) is a Polish Space (i.e., a space homeomorphic to a complete metric space that has a countable dense subset.)
- An everywhere surjective f:A->B is a function defined on a topological space where its’ restriction to any non-empty open subset is surjective.
- For natural number n, the n-dimensional interval, for all i∈{1,…n} of real numbers ai and bi is [a1,b1] x [a2,b2] x … x [an,bn]
Is it true the graph of an everywhere, surjective f in any n-dim. interval covering the subset of the A x B, always countably infinite?
If not, is it true the graph of an explicit, bijective f in any n-dim. interval, where the graph of f is dense in the Rn+1, which covers the subset of A x B always countably infinite?

I am trying to set up a Graphab project and to calculate a linkset. This works fine when using a small crop of the original research area with an external raster file containing resistance values, or when assigning some class-specific resistance values. However, when I use the full extent of the map in combination with an external raster file that contains the resistance values, I get the following error:
"java.lang.RuntimeException: java.lang.IllegalStateException: Negative or null cost is forbidden. Check your cost."
There are no null or negative values in the resistance raster, so what shall I make of this message? Could it have been caused by some other issue not accurately reflected in the error message?

Let M = {v1, v2 ... vn} be an ordered set of minimum number of vertices in a graph G. Then the vector of distances (d(u, v1), d(u, v2) ... d(u, vn)) is called the M -coordinates of a vertex u of G. The set M is called a metric basis if the vertices of G have distinct M -coordinates. The cardinality of M is called Metric dimension of G.
A graph G is said to be (uniquely/ doubly/ triply ) k-dimensional if G has exactly only (one /two/ three) metric bas(i /e)s. In our research journey, we found some family of graphs have exactly 3 metric bases of cardinality 4(Triply 4-dimensional). We are interested to know about some known properties in the literature.
Suppose you have 5 football teams each team meets the other teams once. The total number of matches is 10. We may represent the results of these matches by a graph, in which if team A wins over team B, we draw an oriented arc from vertex A to vertex B. If team A ties with team B, we draw an undirected edge(or we do not draw any edge for simplicity). From the resulting graph, let P(A) be the number of points of the team A. P(A)=3 multiplied by the number of directed arcs out from A plus the number of undirected edges incident on A. Each graph in that manner represents the result of matches and vice versa. From the graph, we can arrange the teams. We can generalize this for n teams.

Hello,
I am measuring stress and strain on tissues in two different conditions and want to see the differences in the stress-strain curve. Since the nature of measurement introduces error during repeated measurement in both stress and strain there is both X and Y error for measurements and I obtain a graph like the one attached below. My question is what would be the correct statistical test to compare the two curves? and how can this be done using graphpad. One of the issue is that the X values are not same for both curves so ANOVA with one-on-one comparison becomes difficult as for the same X value I do not have corresponding Y values.

In our Research Journey, an algorithm and software coding were revealed to me. It is useful to find all metric bases of a given graph in a reasonable time. For some graphs , we get all metric bases in a fraction of a second, but for graphs with 2^7 nodes, we get the first answer in 5 minutes and complete answers ( 73728 bases) for Q(6,3 ) in 12 minutes , and More than 1Lakh metric bases for Q(7,3) with running time, 4 hours, 54 minutes and 30 seconds,( Is It reasonable time?). I would like to know about the existing algorithm (if exist) to find all metric bases of a given graph. It is also interesting to see that the metric dimension of Enhanced Hypercube Q(n,3) is a constant , for n= 3 to 7).

Suppose l_1(L_1) is the Banach space of sequences from L_1 with norm (f_j_j-->||f_1||+||f_2||+... . Suppose L_2(l_inf) is the Banach space of sequences (f_j)_j from L_2 with the norm (f_j)_j-->||sup_j|f_j||. Finally, suppose T:l_1(L_1)-->L^2(l_inf) is a linear map defined by
(f_j)_j-->(T_j(f_j))_j.
It seems to me that the fact that T is well-defined, i.e. all outputs are in L_2(l_inf), AND each T_j is continuous implies T is continuous by the closed graph theorem. This is because the candidate limit (f_j)_j when arguing T has a closed graph has to satisfy f_j=T_j(x_j) where (x_j^n)_j converges to (x_j)_j in L_1(l_1).
My uncertainty stems from the following example. Fix T_1 and let T_j=log(j+9)T_1 for j>2. Since this sequence (T_j)_j is not uniformly L_1-->L_2 bounded, the corresponding operator T cannot be bounded(continuous). However, the slow growth of the operator norms is slow enough so that for (f_j)_j in L_1(l_1),
||sup_{j\le N}|T_j(f_j)|||<=||T_1||(sum_j (log(j+9))^2||f_j||^2)^{1/2}.
I'm just estimating by replacing maximal function on left with square function within the L_2 norm. In other words, since (f_j) in L^1(l_1), the right side of the inequality is finite and independent of N. Does this not imply T is well-defined from L_1(l_1) into L_2(l_inf) and thus contradicting the closed graph theorem argument above.
What am I missing? What dumb oversight am I not seeing?
We wanted to electrodeposit polyaniline by CV analysis.
However, I got an OVERLOAD at the beginning and the gold dropped off a bit.
Later, I ran the CV again and got the following blue graph.
After that, as the gold dropped, the solution turned green, as shown below, can we assume that the PANI was polymerized but not attached to the gold?
Also, as the Pt electrode kept depositing black material and later stabilized, it also drew a blue graph as shown below.
If you know the reason, please reply.
The metric dimension of a graph is the smallest number of vertices from which the vector of distances to every vertex in the graph is unique. It may be regarded as a generalization of the concept of trilateration in the two-dimensional real plane, the idea underpinning the Global Positioning System (GPS).
If resonant frequencies were determined using Ansys modal, and the system is excited at those resonant frequencies with some force, it should vibrate with an increasing amplitude, do we have any way to get a graph of this increasing amplitude with time in Ansys harmonic?

I am trying to report the results of a study that employs a 2 (between subjects: tx vs ctrl) X 4 (within subject: time :T0,T1, T2 and T3) mixed factorial ANOVA. I have analyzed the data using both SPSS and JAMOVI.
Personally, I find the JAMOVI results cleaner and the graphs of estimated marginal means much better because SPSS is not graphing with error bars at all. and JAMOVI tables are much simpler.
Question is: why does SPSS provide a multivariate table here for an analysis that is essentially univariate (One continuous DV), then follows it up with separate tables for within and between subjects factors?
Second, from the JAMOVI output, I have been using the interaction term posthoc testing to breakdown the significant interaction- I wanted to verify this is essentially doing the same thing as a simple main effects analysis. conceptually this is testing each level of each factor within each level of the other factor- so this should be okay, right?

The presence or absence of sharp peaks in the diffraction graph of pure anthracene derivative versus thin films can be influenced by various factors. what are some potential reasons for the observed differences. There is sharp peak in the diffraction graph of pure anthracene derivative but not in the thin films are synthesised
I have been trying to find the phase difference to test whether polarization is converted or not in a metamaterial polarization converter. But I am not sure how to do that.
In the below paper, how did the authors got the graph in Figure-3.
We are using floquet port. We used one method where we go to "floquet boundaries' and then tick the box "polarization independent of scan angle phi" and put +45 once and then -45. we then took the S11 of the two simulations (+45 and -45) and then subtracted the phase of these two.
P.S.- I have attached some screenshots of the changes we did to the floquet boundaries. The last image is the phase difference I got following this method. It matches the figure slightly, but I am confused whether my method is correct or not.
Any help is appreciated.

Hello ResearchGate Members,
I hope this message finds you well. I am currently exploring different tools for visualizing frequency collocations extracted from the AntConc program using network graphs. While I have tried VOSviewer and KH Coder, I've encountered challenges as they don't seem to generate graphs based on simple frequency.
I would greatly appreciate any recommendations or insights from the community on alternative tools or methods that effectively visualize frequency-based collocations through network graphs. Your expertise and suggestions will be invaluable in enhancing my research visualization.
Thank you in advance for your assistance, and I look forward to learning from your experiences.
During calculations, sometimes I face such graphs. I want to know their physical meaning and why they appear. please
I have two graphs of pressure and velocity at a point over the time and they need to be in-phase .
There is a small value of phase difference between these graphs.

Hello,
I am very beginner in TRNSYS. By default the simlation in TRNSYS is hourly. However, I want to plot a graph based on its month. For example, electricity production every month: January, February,..., December.
Does anyone know how to do it?
If so, please give me step by step tutorial such as the type of components, how plot it, etc.

We have been studying the effects of some inhibitors on lysozyme activity. When we look at a graph of product (fluorescence) over time we see a clear inhibition of the enzyme activity that indicates a non-competitive inhibitor. However when we assay a serial dilution of substrate concentration in respect to product we do not get a rectangular hyperbolic graph. Instead we get a line that does not level off? We have decreased the enzyme 10X and used the highest concentration of cells (substrate) that we can but still can see it level off? when we plot a LIneweaver Burk plot the line does not incept the y axis but instead goes through the 0,0 point on the graph? Any suggestions?
Let M = {v1, v2 ... vn} be an ordered set of minimum number of vertices in a graph G. Then the vector of distances (d(u, v1), d(u, v2) ... d(u, vn)) is called the M -coordinates of a vertex u of G. The set M is called a metric basis if the vertices of G have distinct M -coordinates. The cardinality of M is called Metric dimension of G.

I am preparing my Bachelor final thesis in computer engineering. I am currently planning out the work. My idea is to compare traditional approaches to building recommender systems to Graph Neural Network based approaches. The plan so far is to use the Movie Lens 100k dataset, which contains data on users, movies, and user-movie ratings. The task of the recommender system would be to predict the missing ratings for user A and recommend movies based on that (say top 5 highest predictions). I would present three approaches to this task:
- Traditional content-based filtering approach
- Traditional collaborative filtering based approach
- Graph Neural Network
Given this very general outline, would you guys say that this seems like a good project idea? The movie lens dataset seems to be quite popular when it comes to experimenting with GNN's, but you can suggest a better dataset for this setup.

Hi every one, in COMSOL multiphysics (v5.5), i want to simulate two parallel capacitor to know its electrical potential distribution and electric field but when i did that in electrical potential graph, we found a mistake that you can get a 0.5volt even when you are 10mm away from plates, i dont understand how it can be?
assume that you have battery is it possible to get 1volt from 1.5v battery even if you are 10mm away from it? firmly N0!
Directed acyclic graphs are becoming very useful for creating consensus algorithms in distributed systems. It is important to have a metric to measure the complexity of the directed acyclic graphs. Hence this query.
