I asked this question to use satellite imagery to study urban ecosystem changes and find the best satellite imagery suitable for urban planning research. On the other hand, I know that Landsat 8-9 and Sentinel 2 can provide decent images, but the scale obtained from these images is too large.

One often sees wringing of hands when the subject of robots is brought up, the most common objection being, what will people do to earn a living? The same complaint one has heard ever since the beginning of the Industrial Evolution.

Let's be very brief:

The complaint is based on the assumption that corporations own the robots, so the average joe will have nothing of value to offer the economy, will earn nothing, so this plays havoc with the economy.

What if, instead, the average joe owns one or more robots? What if people become the agents of their own robots, and earn their living by selling the labor produced by their robot(s)?

For the time being, I'm not putting limits on the design of the robots. To be very simplistic, assume a humanoid machine, that can literally work in our place. But in fact, robots can also be whatever - vending machines, ATMs, GPS-guided lawn mowers, autonomous cars, and so on.

So instead of removing the value offered by the human, the robot does the work for the human, and the owner is paid for that work.

The economics of actually buying the robots is not too unusual. People can buy robots as they buy anything that's relatively expensive today. The difference being, the robot earns its keep, by being paid directly for its labor, while, for example, a car is just an expense, for most people.

In short, the drudgery is taken away from the human worker, but a human individual is still being paid for doing the work.

Greetings, Respected Researchers,

I am an emerging researcher in the field of agriculture science and a Masters Candidate.

As part of my thesis, I have my data at hand and need an expert to help analyze the data using SPSS (both qualitative and quantitative). I am new to SPSS and don't know much about it.

Anyone who has deep knowledge or is an expert and is willing to help me would be appreciated. I can also pay the cost of the work you will do.

Numerous research are carried out globally if there are rules, they would confiscate or bias the outcomes. On the other hand,though we are against the bias it is sometimes impossible to go out of the box.

I have recently published a paper in the Skeptical Inquirer review (Volume 48, No. 6, Nov./Dec. 2024): https://skepticalinquirer.org/2024/10/is-science-progressive-or-conservative/.

I would love to read your reactions!

Here is the introduction (you can read more if you click on the link above + the great audio version):

In our modern world, we consider science to naturally go hand in hand with progress.1 These two concepts are almost perceived as synonyms. Science is progress; I believe in science as I believe in progress. We then consider ourselves progressive, as supporters of progress, “moving forward” in the etymological sense of the word. Progress is often opposed to conservation, with the latter being seen as a symbol of inertia, i.e., resistance to change. In the eyes of the general public and progressive intellectuals, science—which is constantly advancing—cannot be conservative. By conservative, I mean preserving, safeguarding, and maintaining things, structures, and unchanging ideas. But is science only progressive?

Scientific ideas are often seen as revolutionary, wiping away the past, the tabula rasa. However, while ideas evolve, change, and modify, they still preserve certain older ideas that inspire the new ones. In this sense, we will see that science preserves more than it changes. But this is not opposed to progress. Actually, the foundation of science itself obeys a law of conservation, despite being in constant motion. As for scientists, Albert Einstein is the famous symbol of both scientific and political progress (Person of the Century 1999). We often hear that he revolutionized physics and our understanding of nature. However, the historical reality is more complex than we think. Einstein could be a staunch conservative in many aspects, while other scientists who are perceived as more conservative were more open to progress.

This article examines the contradictions and hesitations between progress and conservation inherent to science and the people who shape it through the illustrious example of Einstein. We will defend the thesis that sciences are built in the image of nature, i.e., preserving what needs to be preserved and constantly evolving to endure. At the end, we will support the idea of the existence of a complementarity rather than a dichotomy between progress and conservation in the construction of science.

Good day. Is it wise to buy a second hand cfx 96 in good condition without any software?

Hi, as a synthetic chemist, I decided to look into basics of UV spectroscopy. The thing I got stuck with is the enrrgy of a specific transition (for d3 octahedral ion - due to Td-Oh and electron-hole expansions can be generalized to some other configurations):

For the (F)⁴T₁g state, however, the correct value is +0.6Δoct (I checked a handful of textbooks but could not find an explanation. Note that the electron repulsion term x should not be relevant as it is explicitly treated in the next step and the final energy of the ⁴T₁g state is 0.6Δoct-x. (the d3 octahedral Orgel diagram from Housecroft, C. E.; Sharpe, A. G. Inorganic Chemistry, 4th ed.; Pearson: Harlow, England, 2012, p695 with a few notes is attached) Am I missing something?

The debate about introducing eSports to the Olympics has been ongoing, and opinions are divided. On one hand, eSports has gained immense popularity globally, with a huge following and significant prize pools. Including eSports in the Olympics could attract a newer, younger audience and provide a platform for gamers to compete at the highest level ¹.

On the other hand, some argue that eSports doesn't align with the traditional Olympic values and spirit. The International Olympic Committee (IOC) has expressed concerns about the violent content in some eSports games, which might not be suitable for the Olympic platform ².

Despite these concerns, the IOC has taken steps to incorporate eSports into the Olympic ecosystem. The inaugural Olympic Esports Week was held in Singapore in 2023, featuring games like Virtual Regatta, Tic Tac Bow, and Gran Turismo 7 ¹. The IOC has also announced plans to create an Olympic Esports Games, with the first edition scheduled to take place in Saudi Arabia in 2025 ³.

Ultimately, whether eSports should be introduced to the Olympics is a matter of personal opinion. However, with the IOC's efforts to explore the possibility of including eSports in the Olympic program, it's clear that the organization is open to embracing new and innovative forms of competition ⁴.

With the advent of the AI, the researchers across the globe are tempted to benefit from its substantial contribution to promoting their publications. Now, the issue at hand is the extent to which researchers can be deemed justified to use the AI help in preparing their article manuscripts to submit for publication, without having violated the ethics of research.

I propose a discussion on my PDF-PowerPoint "Artificial Intelligence and Education: questions, opportunities, and perspectives". I used this PDF-PowerPoint for the lecture held as keynote speaker at the International Conference "Education & Artificial Intelligence", organised on Saturday, 9th November 2024 by the FACULTY OF PHILOSOPHY - WIDYA MANDIRA CATHOLIC UNIVERSITY OF KUPANG. The development of Artificial Intelligence in different sectors has produced noteworthy changes: for instance, healthcare, financial sectors, and manufacturing have experienced profound changes due to the application of Artificial Intelligence. The education system is no exception in relation to the application of Artificial Intelligence: the sector of education has already experienced changes and will experience changes in the future, due also to the progress which Artificial Intelligence is making year after year. The theme of Artificial Intelligence in education has different aspects. On the one hand, the application of artificial intelligence gives the opportunity of personalised and efficient learning; it gives moreover the opportunity to improve the teaching activity. The chance of an automated assessment of the students is then to be added. Therefore, both the teaching sector and learning sector are interested by the application of Artificial Intelligence. On the other hand, ethical questions are connected to the subject of Artificial Education. Like every profound reform, the application of artificial intelligence in the sphere of education will confront us with a multi-faceted situation in which we shall find, at the same time, advantages and problems. The questions will go on for years and years: learning and teaching will experience profound changes so that the problems connected to the changes will be several. Due to the complexity of the questions connected to Artificial Intelligence, the questions of the application of Artificial Intelligence in the sphere of education ought to be discussed by teachers, parents, and directors of schools, i.e., the complexity of the question cannot be discussed exclusively in one environment: the complexity of the subject asks for analyses which ought to be fulfilled in different sectors. The discussion within the sector of the school is necessary, but not sufficient to investigate all questions connected to the application of Artificial Intelligence in the education of pupils. The discussion and the analysis of the problems connected to Artificial Intelligence ought to be fulfilled within the families of the pupils too.

I have LCMS test data in my hand. I need help how to analysis what compounds/substances are there (The material is crude plant extract). I'm attaching the full chromatogram for reference. It would be very helpful if I could be pointed to some resources for making sense of this result.

There are frequently raining in Saudi Arabia nowadays, and causing floods, because Saudi Arabia is not well advanced in their building with draining system for water management.

Saudi Arabia must work on their water management draining system and to dig up reservoirs to restore rain water for water supply to country.

Raining in Saudi and Middle East countries is caused by Climate change effect . We are in the early stage of the Maunder minimum, the expected mini ice age to be. On the one hand the rising Emissions, on the other the Solar ecliptic impact, of Maunder Minimum.

However, it is important Saudi Arabia and other Arab nations do retain rain water to recycle and supply.

As I have Action Plan, for climate solution suggestions, I will explain what I drew in the plan for the whole planet earth. I previously explained situation about Saudi Arabia in the past Mini Ice age.

Has anyone an experience in this case ?

I have a system of three nonlinear equations and three unknowns. I have solved it by hand and by matlab function, fsolve also. Now, if I have a system of four nonlinear equations and three unknowns; the matlab function, fsolve is not able to find any solution. Is there anyway to solve it?

Hello everyone,

I'm planning to develop cancer model using CCl4, i have been search to disposal and detoxified method to handling tools, waste, and animal used for this research. But, unfortunately I don't really find that I looks for to detoxified tools and animal handling care. The dispose and detoxified method from literature, MSDS, and some goverment procedure I got was not mentioned how to detoxified CCl4, It just mentioned to use absorbant for any spill of CCl4. For animal I suggested it need to treat like hazardous waste for 24 hours after injection of CCl4.

Does anyone can share experience for handing the animal waste that using CCl4? and how to detoxified tools that have been use/contact with CCl4? or it just can use large amount of soap water to rinse the tools?

thankyou for everyone that have been answer

Rather a technical question directed to the moderators of RG: What happened to the standard settings of "Home" on RG?

I'm experiencing the following: Since a couple of days It is not indicated any more when an update of potential interest (to me) was posted. I just have to assume that the last ones are still near the top of the list. In addition the number of updates has become very limited. Normally I receive some 10 to 20 updates per day, but now it's less than a handful.

I did not change my settings, but perhaps RG did. If you have recently experienced the same issue, just give a short reply.

Case study on a 22 year old male Hirayama case with left distal hand weakness along with providing physiotherapy intervention to see the before and after results. Is it a feasible one ?

We assume that the difference is huge and that it is not possible to compare the two spaces.

The R^4 mathematical space considers time as an external controller and the space itself is immobile in its description or definition in the face of curl and divergence operators.

On the other hand, the unit space 4 D x-t time t is woven into the 3D geometric space as a dimensionless integer.

Here, the curl and divergence operators are just extensions of their original definitions ​​in 3D geometric space.

We have an Eppendorf Concentrator plus complete system, with the included F-45-48-11 rotor. I can't get it to spin, only dessicate (and when it does this it just vibrates slightly, leaving the solid precipitate all along the sides of the sample eppendorf tube walls).

On the 'CEFU' or 'C-' settings, the rotor moves slightly, clicks and the screen says 'Error 2'. Would anyone be able to advise what I should do? I have checked in the product manual and have tried moving the rotor by hand which works. There is nothing obstructing the rotor, no problem with max load (the error message occurs even when the rotor is empty), and it looks like the rotor is mounted correctly.

Thanks so much and all the best!

Hi,

I need to analyze a MIMO antenna. Can someone please share SAR models for Head and Hand Analysis?

To calculate the average daily water surface temperature in a small water reservoir such as dams, no reliable dataset is provided for use in Google Earth Engine. Some people say that the temperature of the earth's surface(LST) or the skin temperature, which is presented in some datasets, can be considered as the temperature of the water surface, which is wrong. On the other hand, by using Landsat 8, you can make a good approximation of the water surface temperature, but its data is momentary and does not take into account the daily average... In your opinion, what is the best method for calculating the daily average temperature of the water surface by remote sensing in small water body?

Hello everyone,

I'm writing a research paper about the neurocognitive effects of COVID-19. I had 22 items in the survey referring to various cognitive impairments; taste/smell, use of hands, information processing, high level functioning, memory, and language/communication. I had to do factor analysis to group them for further analysis. In "component matrix," it looks like there are 2 categories I can create: 1. Taste/smell (first 6 items connected to this category) and the rest are together, I labeled them as "other cognitive impairments." Now I need to prepare a table to show factor loadings. I was checking which table in the output I needed to use for factor loadings, it says there should be a table labeled as "Rotated Component Matrix" but I don't have it in the output. I tried to see what I did wrong but everything looks correct. I used direct oblimin because for example the first 6 items refers to taste/smell, in correlation table I see there are some degrees of correlation between the items, not only for taste/smell but also in other areas.

My first question is do you have any idea why I don't see "Rotated Component Matrix"?

Second question is which table do I need to use for factor loadings? I thought I need to use "rotated component matrix," but I don't have it. I'm so confused about from which table do I need to report the factor loadings.

and lastly when I'm preparing the table, should I report it as how the factor analysis revealed? For example: Factor 1: Taste/Smell - Factor loadings: .... Factor 2: Other cognitive impairments - Factor loadings: ... OR as Factor 1: Taste/Smell, Factor 2: Use of hands, Factor 3: Information processing, etc.

I provided the output for factor analysis. I would really appreciate it if you could help.

Thank you so much.

Dear all

Does anyone know how to implement a minimum distance estimator in Stata? I have the parameters and the var/cov matrix from an unrestricted model and would like to estimate the following function:

Br = argmin(Br - Bu)*IM*(Br - Bu) subject to fi(xi, Br) >= 0

with IM the inverse of the var/cov matrix, Bu the Betas from the unrestricted model, Br the Betas from the restricted model and fi the derivative of the dependent variable with respect to each of the regressors (this is a translog production function, hence this derivatives do not correspond to the first order coefficient of the corresponding regressor but depends also on the crossed-effects, but that is not really relevant). How can I to do this in Stata? Please lend me a hand. This is the last thing I need to finish and publish the first article of my phd.

I posted on the Stata forum but haven’t got a response yet and this really urges me.

Please.

Thank you all,  Juan

Hello everyone, I have some question to discuss with you, looking forward your help!

1, As we can use phase modelling method to estimate the melt vol% of a rock by its bulk composition, can we use the estimated result to link the real sample' melt content?

2, Do you have any methods to estimate the melt vol% in the migmatite through petrographic observation, hand sample or even the field observation?

I know I'm crossing a minefield in investigating this question.

There are at least two incompatible theories:

classical EM theory, where wave energy is continuous and

QM quantum theory, where the energy of EM waves is essentially discrete or quantized in photons.

So it depends on the theory we use to analyze this problem, not on the frequency of the wave.

If we follow QM theory, the answer is definitely no because the photon must have a positive momentum and therefore a positive frequency.

On the other hand, if we follow the classical theory of electromagnetic fields, the answer is yes but the photon itself is not defined.

Hi,

I have two rotamers from crystal structure data. I like to use the QST2 transition state search in Gaussian to investigate their interconversion barrier. Since they come from crystal structure data, the atom numbering/ordering of the two optimized rotamers is different. With around 100 atoms, I would really prefer not to try and renumber them by hand. Is there any automatic structure match and renumber routine out there, which would produce the two geometries with matching numbering?

Alternatively, if I have to go via the "traditional" TS search: is there any program which would allow to match/align two structures and to calculate an "averaged" structure from this? But I assume those would also require matching numbering...

A new trend of open an transparent peer reviewing is growing. In one hand, this would encourage reviewers to actively review because this save their intellectual property they add to the articles. In addition review reports will be more serious. On the other hand, being exposed to the Author(s) may lead to some critics. Please add your thoughts.

A new disease is beginning to appear in humans, which is now being remembered as AI.

There are many questions about this disease, but the important point is to control our mind and body with our own hands.

Salt water does not evaporate faster than fresh water; in fact, fresh water always evaporates faster than salt water. This is because of the difference between the salt and water molecules. Water is a slightly volatile substance, meaning that it is capable of evaporation, while salt is a nonvolatile substance, so it is not as capable of evaporation.

Evaporation takes place on the surface of a substance. Fresh water has only water molecules on its surface area, which lets it evaporate easily. Salt water, on the other hand, has both salt and water molecules on its surface area. The salt molecules take up part of the surface area and prevent the water molecules from evaporating as quickly, which is why salt water always evaporates more slowly than fresh water.

Wikipedia mathematics suggests that the volume of a four-dimensional hypercube (tesseract) of side length "a" is 8 a^4.

On the other hand, the B matrix chains predict the volume of a four-dimensional hypercube with side length "a" (tesseract) as simply a^4.

The question arises which answer is true, if any?

I am wondering about publishing a protocol for an interventional, prospective trial, but I am unsure about funding the trial. On one hand, I believe publishing a study protocol generates interest, on the other hand, I am not sure if there will be funding or participation from the relevant clinics.

During my research for my bachelors thesis into the classification of mining in the Reichsgruppe under the Nazi regime, I came across two different classifications:

So which is correct?

I can only explain this apparent double classification by the central importance of mining for both economic sectors: On the one hand as a supplier of raw materials for industrial production and on the other as a key sector for energy supply.

Is it possible that in different sources and at different times the emphasis was placed more on one or the other affiliation, depending on which aspect of coal mining was in the foreground, so that it can be said that mining belonged to both groups?

I propose as a subject for a discussion the PDF-Powerpoint of the lecture "Analogies between Plotinus and Indian Philosophy" held on 1st March 2024 at the International Conference on Topic: Cultures in Transformation: A Subcontinental Experience International Conference organized by the Department of History in Collaboration with Northern Region Centre Indian Council of Social Science Research (ICSSR), 1-2 March 2024, Ram Lal Anand College, University of Delhi. I am working on a text connected to the PowerPoint. In my inquiry, I would like to expose some aspects of Plotinus’ thought which have, in my opinion, analogies with aspects of Indian Philosophy. I shall therefore concentrate my attention on Plotinus’ conception of the One, on the relations between One and multiplicity, on the separation of the individual from the One and on the return to the One. I shall then investigate the opposition expressed in the Upanishads between inauthentic reality and authentic reality, the initial position of the individual in the darkness and the return of the individual to the true dimension of reality. The individual’s ascent to the One in Plotinus and the liberation of the individual from the dimension of multiplicity will be a central theme of my exposition since it constitutes one of the analogies with some passages of the Upanishads in which the process of liberation of the individual from the ties of the average sense reality are described: the initial position of the individual as a position of decadence of the individual will be exposed by resorting to different passages of Plotinus’ Enneads.

The opposition between knowledge and opinion, on the one hand, and between intellect and sense perception, on the other hand, will be investigated in order to see the similarities with passages from the Upanishads in which the opportunity of a progressive detachment from the sense dimension is insisted on.

The common ground between Plotinus and the Upanishads proves to be the conception of philosophy as the revelation that the average way of living is inauthentic, that there is an authentic dimension of reality, that the individual ought to reach the authentic dimension of reality, and that a long process of training is needed for the individual to be able to reach the authentic dimension of reality. Furthermore, the description of the position of the One as an entity which is beyond all predicates can be analysed, in my opinion, with particular attention to the analogies which this subject can have with the descriptions of the nature of Brahman.

The main texts on which I will base my inquiry will be Plotinus’ Enneads, on the one hand, and the Upanishads, on the other hand.

Dear All,

Could you tell me how to run MD simulation by any software. I have DS, VMD in hand. But I try to run 30 nsec in DS that spent 6 days, is that right? The reviewer asked me to perform this procedure in 100 nsec, however, my computer can not complete this process. Could you let me know how set up all parameters and settings to finish them. Many thanks for your help with my deep heart.

Is the only way people can get copies of articles from an author, is for the person asking to go through the CCC site and pay for the articles at those high rates? Is there anyway I can just send them a copy of my paper digitally from my files? On your page with the requests, it has buttons for "publicly share paper." Is that where I can just upload my digital copy of the MS, and they can download it from there? I am getting mixed messages from your site as opposed to the CCC process which seems more like censorship than in the old days when an author could just send a copy to the colleague on their own without any money changing hands. Thanks.

Time is money! The fact that a dollar received tomorrow is not equivalent to a dollar in hand today. It is the fact that money always can earn a positive return that lends importance to the time dimension. A dollar given up today is not the equivalent of a dollar received in the future as long as there exists the alternative of earning a positive return on the dollar during the interim.

Is the time value of money only dependent on the affordance of a person or an organization to invest the equivalent amount of money?

Would anyone happen to know how the percentages are calculated in SPSS for the predicted and observed categories? Is it something you can do by hand or does SPSS use some kind of internal calculation? The type of output I'm referring to is the screenshot below. Huge thanks in advance for any help!

Naturally, denotation in language is based on connotation in minds and this in turn is based on ontological universals in nature (in natural kinds), which (ontological universals) are vaguely reflected in connotative universals. Hence, denotation is primarily a linguistic function; and connotation is the reflective function of consciousnesses. Ontological universals are the generalities that properly and only belong to existing processes in their many members within groups. Languages are not merely what we directly call so. Metnal notions, feelings, and thoughts on the one hand (all of them in causal matter-energy mixture with brain-body elements), and language representing all sorts of expressed notions and thoughts on the other, are the two type of information engendered by BI. That is, BI information is a group of concatenations of denotatives, based on the concatenations of the respective connotatives. A similar chraracterization of AI information should appear as a result of further discussion, after developing some more background for the same.

Dear all,

Even though I am passionate about PV energy it is well-known that EVs substantially benefitted from the PV generation in neighbourhoods and also in detached houses. Now I see how big car manufacturer seems to have put all the eggs in the same basket, EV mobility. They are turning to electric fleets their fleets, which will definitively overcharge/stress the utility grids by 2050.

On the other hand, only a punch of them bet for H2. Everybody knows this is not only an abundant resource but also costly to produce and tough to store. In the end, an interesting resource to bear in mind. Lately, I wonder if there is still time for mobility based on H2. I mean, private cars not large fleets of trucks or busses, I am referring to family mobility.

I would appreciate your thoughts and reflections on this theme.

Best regards

I would like to obtain useful answers in this regard, in order to solidify scientific research on the one hand, and to obtain approvals to publish with certainty, in scientific journals indexed in the Scopus and Clarivate databases on the second hand.

We assume that the most important similarity is that both describe how the energy density function U(x,t) moves in 4D x-t space.

On the other hand, the most important difference is that in the heat diffusion equation the energy density function can be constrained inside a box of Dirichlet boundary conditions, whereas in the Schrödinger equation, it cannot (the wave function 𝛙 extends by definition to infinity).

Of course, you can add many similarities and differences, but how?

Hello!

i'm a 1st year doctoral student, working on "deep learning applications in engine control and diagnostics", so far i've had to create a number of models. However, I'm having trouble training these models to assess their accuracy, due to a lack of data. The data in question are, on the one hand, cylinder pressure, cylinder temperature, compression ratio....etc, which can characterize the state of health of a part or an associated engine component. On the other hand, data from certain parts whose state of health can be determined by vibrations.

how can i enter these types of data? Can anyone help me?

Thank you!!!

Thank you this question has been answered.

I actually think on the one hand that it is possible to determine this absolute time and on the other hand that it is this absolute time that will justify or not the value of CODATA c=299792.458 m/sec. For me c=299792.375 m/sec from Arne BERJHAMMAR is more accurate.

Dear colleagues,

for my current research project I am trying to trace the effects of a CJEU verdict in 2011 via migratory activity of scientists. To do so, I need to obtain data that shows a year-name-affiliation link for scientists working in the respective field. So far I have used Scopus, but the database gives me the information in a format that is impossible to work with. I could do this by hand, but I would rather avoid sorting several thousand entries by hand, so I was hoping that there was a database that would enable me to retrieve the required information in a standardized format. So far I have tried Web of Science, Scopus, JSTOR, PubMed and Publish or Perish, but to no avail.

Thanks in advance!

I recently began to work with viviparous Neotropical skinks of the genus Mabuya. Specifically with females at different stages of gestation. My tutor and lab colleagues have studied them for a long time and a recurring comment is related to the difficulty of field sampling.

The standard method of catch is by hand, but these lizards are very quick moving through the litter, and their smooth-scales covered skin makes them difficult to hold. Also, in the most advanced stages of pregnancy, these lizards stops feeding so funnel traps will likely be less effective.

I have little experience in catching, and I am planning some field trips to obtain some specimens (especially to learn about the field work). I would like to try different catch methods, hoping to make it easier to obtain research material.

I will be very grateful for any suggestions or advice you can provide.

I conducted some experiments using strain gauges mounted in a wheelchair hand rim to determine differences in push force over a short course. Changes in tire type and tire pressure are related to differences in strain measurements over the course. The differences are statistically significant but are expressed as mV/V which are the raw strain gauge outputs. I have mass, distance, and time over the course.

Dear ResearchGate members,

On one hand, there is a theory giving the reflection/transmission coefficients when acoustic planes waves propagating in a medium (rho0, c0) reach a finite thickness object (rho1, c1) with normal incidence. Such theory basically gives the thicknesses (n*lambda1/2) at which the object is theoretically acoustically transparent - of course, the width of the reduced reflection depends on the impedance mismatch between the 2 media – and the thicknesses ([2n-1]*lambda1/4) at which the object is fully reflective.

On the other hand, there is also theory giving the variation of the reflection coefficient depending on the incident angle of acoustic plane waves at the interface between two semi-infinite media (rho0, c0; rho1, c1). Over a critical angle (depending on the impedance mismatch between the two media), the reflection is theoretically total.

Now, here is my question: What is the behavior of the acoustic waves when the two phenomena are considered at the same time? If the plane waves reach a surface with an incident angle, and the reflective medium is finite in thickness (acoustic mirror)?

By experience and through simulations, it appears that over the critical angle, the reflection is not total, even with a mirror thickness for which the reflection is theoretically total.

Thanks a lot in advance.

I propose a discussion on "Analogies between Plotinus and Indian Philosophy" - PDF-PowerPoint of the lecture held by me on 13th September 2023 at the 2nd International Conference "The Greek World and India: History, Culture and Trade from the Hellenistic period to Modern Times (4th c. BCE – 18th c. CE)", jointly organised by the Hellenic Institute of Byzantine and Post-Byzantine Studies in Venice and by the Jawaharlal Nehru University New Delhi, Venice, 12-13 September 2023. In my inquiry, I would like to expose some aspects of Plotinus’ thought which have, in my opinion, analogies with aspects of Indian Philosophy. I shall therefore concentrate my attention on Plotinus’ conception of the One, on the relations between One and multiplicity, on the separation of the individual from the One and on the return to the One. I shall then investigate the opposition expressed in the Upanishads between inauthentic reality and authentic reality, the initial position of the individual in the darkness and the return of the individual to the true dimension of reality. The individual’s ascent to the One in Plotinus and the liberation of the individual from the dimension of multiplicity will be a central theme of my exposition since it constitutes one of the analogies with some passages of the Upanishads in which the process of liberation of the individual from the ties of the average sense reality are described: the initial position of the individual as a position of decadence of the individual will be exposed by resorting to different passages of Plotinus’ Enneads. The opposition between knowledge and opinion, on the one hand, and between intellect and sense perception, on the other hand, will be investigated in order to see the similarities with passages from the Upanishads in which the opportunity of a progressive detachment from the sense dimension is insisted on. The common ground between Plotinus and the Upanishads proves to be the conception of philosophy as the revelation that the average way of living is inauthentic, that there is an authentic dimension of reality, that the individual ought to reach the authentic dimension of reality, and that a long process of training is needed for the individual to be able to reach the authentic dimension of reality. Furthermore, the description of the position of the One as an entity which is beyond all predicates can be analysed, in my opinion, with particular attention to the analogies which this subject can have with the descriptions of the nature of Brahman. The main texts on which I will base my inquiry will be Plotinus’ Enneads, on the one hand, and the Upanishads, on the other hand.

The interpretation of the results of EIS is divided into two parts. on one hand, some researchers insist that larger semicircle is better because it leads to larger recombination resistance (Rrec). On the other hand, similar to your interpretation, some researchers insist that the smaller semicircle is better, resulting in small charge transfer resistance. Which is correct between the two views? How can we justify our analysis?

To start with, I want to believe for a modification of an algorithm like evolutionary algorithm to be considered novel, it has to offer some benefit (like automation) and should not perform worse than the manually designed algorithm.

Base on the above, If I want to implement an evolutionary algorithm to design another evolutionary algorithm, I wouldn't know before hand whether the proposed method will perform as good or even better than the manual method or some other similar method.

I can only tell how the method performs after the completion of the implementation.

Is there a way to know before hand that a proposal will not bring some benefit, before putting energy and time into developing it?

Please, what do you advise in this situation from your experience?

Thank you in anticipation of your kind response.

I'm looking for online resources for researching on hand tools and power tools.

It is a growing tendency among authors to publish results without cross checking own results . This attitude generate wrong idea in new readers mind . On the other hand authors

get promotion by showing the wrong results .

They do not feel anything . Give your view .

Hi everyone,

I've been doing a EFA with ML extraction and Promax rotation, whereby three factors were extracted. For reporting the results, I was wondering whether to use the 'Initial Eigenvalues' or the 'Extracted Sums of Squared Loadings' (see file attached). On the one hand, initial Eigenvalues are the ones used for parallel analysis, but on the other hand - as least as far as I'm aware of - the cumulative % of variance explained that is reported is the one below 'Extracted Sums of Squared Loadings'.

Could someone please elaborate what those two mean and which one to choose? I'd highly appreciate your help.

I want to learn about Solving Differential Equation by using "Discrete Singular Convolution"method. I want to learn this method, if someone has hand notes it would be great to share with me. I need to learn that in 2 weeks. Thanks in advance.

AI can be a double-aged sword. Generative AI tools might be difficult in identifying differences in machine learning text and general text essay. Academia might have an even bigger challenge on its hands????

I doing my Ph.D. I working on secondary data, financial literacy is one of mediating variables of my research work. most the studies use 1st hand data i.e. primary data based on questionair for financial literacy. but it is difficule to use the qustionair base data in time series research. please suggest some workable suggestion on the issue.
