Hello, What physical value do you think is interesting to compare my car static torsional stiffness (kN·m/degree) values ​​with? The volume of the car? the mass ? its length? or something else ? looking for correlations. If you have any interesting graphic suggestions and tell me why. Thank you.
Relevant answer
Answer
This is the ratio of applied torque and angle of deformation, where F is the force caused by the applied mass and L is the length from the point of the force to the point of rotation. The value of torsional stiffness is useless unless it is not compared, usually com-pared with the roll stiffness of the suspension. As the vehicle has two axles and each can have a different roll stiffness, influence by linear and nonlinear suspension system.

Now a days, core subjects in Engineering such as electrical, electronics, chemical, mechanical and civil apart from computer science are getting least priority for option. These days everything is controlled, operated and done by software based instead going manually or making decision collectively. Most people are depending on what computer says to follow or understand in several fields. Will this continue or in what way does other subjects may or shall occupy a prominent position or importance on par with computer science?
Relevant answer
Answer
The increasing prominence of computer science in various industries, including engineering, is due to its role in automation, data analysis, and efficiency enhancement. However, core engineering subjects such as electrical, electronics, chemical, mechanical, and civil engineering remain crucial. Computer science complements and enhances these disciplines rather than replacing them. Interdisciplinary collaboration, automation and control, simulation and modeling, hardware design, and domain-specific challenges are some areas where core engineering subjects retain their importance. The integration of computer science and engineering leads to advancements and innovations that benefit society. Recognizing the value of both fields and fostering interdisciplinary collaboration is essential for future progress.

Hello !
I am interested in purchasing a non-intrusive flow meter for measuring the flow rates for different fluids circling inside enclosed pipes. I've seen the ultrasonic flow meters as a possible solution.
Can anyone recomend me some manufacturers and/or links ?
Thanks !
Relevant answer
Answer
There are some excellent ultrasonic flow meters available but read carefully claims of accuracy and note all disclaimers. While these might achieve a high level of accuracy under certain ideal conditions in a laboratory, this does not mean that you can stumble up, clamp one on to any old pipe anywhere, and measure the flow to that same accuracy. Accurately measuring any flow in any pipe is an extremely difficult and complicated task, regardless of the instruments used. There are many good references on this subject published by ASME, CTI, IIHR, USNRL, TVA, etc.

Do obstacles in a channel change the regime from laminar to turbulent while the Reynolds number is under 2300 (approximately 1000)?
Please introduce related studies.
Relevant answer
Answer
The Reynolds number UD/nu=2300 is based on a smooth circular pipe of diameter D, with STEADY mean flow velocity U and fluid of kinematic viscosity nu. Below this critical Reynolds number any perturbation due to an obstacle will not cause persistent turbulence to occur far downstream of the obstacle. Of course locally the wake of a blunt body placed in the pipe can be turbulent, but soon the flow will relaminarize if we travel further downstream. Above Re=2300 the flow does not need to be turbulent. It can be turbulent if there is a sufficiently large initial upstream perturbation. In principle the flow can remain laminar if the inlet is very smooth and care is taken to avoid vibrations. Experimentally fully developed laminar pipe flows have been achieved for Re=500. 000. It is important to realize that this critical Reynolds number does depend on the geometry of the cross-section of the channel. For a rectangular channel of height h and width w >>h, usually one considers a Reynolds number Re=Uh/nu based on the channel heigth. The critical Reynolds number for allowing turbulence is around Re=hU/nu=1100. There is however much less literature on flows through slit shaped channels than circular pipes. If you consider an open channel flow, clearly the critical Reynolds number will be quite different from Re=2300 and of course it does depend on the length scale used in the definition of this Reynolds number!

Question

In the past two decades, many robust structural reliability methods have been presented that we may not even have heard their name. For a reliability researcher, it is very difficult to read all manuscripts, write their code and properly examine their efficiency/accuracy. On the other hand, it seems that some efficient/robust ones are being forgotten.
The purpose of this discussion is to create a space for the exchange of experience and expression of reliability researchers' views/opinions about the structural reliability methods. I hope this could help us to save time and learn more.
Suppose that you have a real-world structural reliability problem without any information about its limit state function, geometry of the performance function and the safety level of the problem (i.e. the performance function can be estimated by a finite element method-based software).
Among the existing reliability methods, which one is your choice? Why?
Let us discuss this. Share your experiences to help others.
Relevant answer
Answer
Dear All,
Hello!
About two years ago, I asked the following question from myself and shared it with you:
“Suppose that you have a real-world structural reliability problem without any information about its limit state function, the geometry of the performance function, and the safety level of the problem (i.e. the performance function can be estimated by a finite element method-based software).
Among the existing reliability methods, which one is your choice? Why?”
I highly appreciate your consideration and contribution. During these days, besides reading your comments, I had an enjoyable collaboration with Matthias Faes (and nice discussions with Prof. Karl Breitung and Marcos Valdebenito) for this issue. As a result, the following is our attempt (Matthias and I) to mathematically answer the proposed question (and some other popular questions) which is published as a paper: .
I can roughly reduce our understanding and the topics of our study to the following points:
1) For a black-box problem with no information about the in-hand problem, if you are looking for efficiency, mathematically, no reliability method is preferable to others!
2) No-Free-Lunch theory says: if a method looks awesome for solving a certain class of problems, essentially, it performs badly for all remaining sets of possible problems! Therefore, if some information about the in-hand problem is available, the important thing for efficiently solving the problem would be human reliability in the selection of the proper reliability algorithm (e.g. understanding the geometry of the problem and accordingly, selecting a proper algorithm which is fit to the information of problem)! You may penalize with a huge function call or/and wrong results in the analysis if employ the wrong person for solving a simple/complex problem! This means that the main problem in reliability analysis is (often) not algorithms! It is practitioners that select bad algorithms for an in-hand problem.
3) Among several practitioners, and for a wide range of alternative reliability algorithms, which practitioner may distinguish the proper algorithm better than the others? Considering the selection problem as a “decision making under uncertainty” and the practitioner as a classifier, we provided some information about the potential application of detection theory in reliability analysis. Detection theory provides a nice mathematical tool for investigating this issue. Using this idea, in future studies, one may design an agent (in machine learning) for the selection of a proper algorithm for solving problems in certain fields (not possible? Ask ChatGPT! ;) ).
4) The last two comments say that the reliability analysis is a “human-in-the-loop” process (e.g., the decisions of a human are a part of the reliability process). In the paper, instead of using the belief of a practitioner, we suggest a solution for fusing the beliefs of experts (we just replaced the belief of experts with the reports of sensors in fusion theory!) regarding the selection of proper algorithm in solving a certain problem (replacing the human-in-the-loop with an experts-in-the-loop process). In this case, some fusion problems are solved in detail and in simple words!
Of course, this is not the end of the issue and our study is just looking at the topic from a different perspective. We hope the materials provided in the paper are useful.
I would be grateful if you share your opinions/ideas about the proposed topics here (or through email).
Regards,
Mohsen

Dear Rahim Alijani,
Your Questions and comments are appropriate regardless of your sarcastic tone.
[1] Any Concept
There are more than 50 innovative keys per concept and more than 100 new pieces of information. We call the new field of knowledge -- Unified Concept Engineering (UCE), and each innovative key requires Abstraction, and this led to an innovation in the Art of Abstraction (FAA). So imagine having 50+ innovations we know, use, develop, and others per concept.
Some of the innovative keys per concept are;
1. Ultimate goal
2. Functional requirements
3. Non-functional requirements, which include more than ten innovative keys
4. Behavior
5. Role
6. Responsibility
7. Applicability
8. Rule of conduct and others
I will publicly cover and spread the innovative keys per each concept we finalized. Why?
1) The Concept is the cornerstone of everything we speak and utilize.
2) Understanding the concept we speak and utilize.
The UCE led to more unified and stable innovations in Domain, Natural Language, and others.

Transfer learning is a machine learning technique that involves using a pre-trained model on a large and diverse dataset as a starting point for training a new model on a related but different task or dataset. Transfer learning has shown promise in enhancing complex systems by leveraging knowledge from similar domains or applications to improve performance, reduce training time, and overcome data scarcity issues.
Here are some advances of transfer learning in enhancing complex systems:
  1. Improved performance: Transfer learning can improve the performance of a model by leveraging knowledge from a pre-trained model on a large and diverse dataset. By using a pre-trained model as a starting point, the new model can learn faster and perform better on a related but different task or dataset.
  2. Reduced training time: Transfer learning can reduce the amount of time and resources required to train a new model from scratch. By using a pre-trained model as a starting point, the new model requires less training time and computational resources to achieve comparable or better performance than a model trained from scratch.
  3. Overcoming data scarcity: Transfer learning can help overcome data scarcity issues in complex systems. By leveraging knowledge from a pre-trained model on a large and diverse dataset, the new model can learn from a smaller dataset or a different domain with limited data, which can be useful in many real-world applications.
  4. Adaptation to changing environments: Transfer learning can help enhance complex systems by enabling models to adapt to changing environments or situations. By using a pre-trained model as a starting point, the new model can quickly adapt to new data or scenarios, improving the model's performance and robustness.
  5. Facilitating knowledge transfer: Transfer learning can facilitate knowledge transfer between related domains or applications. By using a pre-trained model on a similar task or dataset, the new model can learn from the pre-trained model's knowledge, resulting in better performance and faster convergence.
Overall, transfer learning has shown great potential in enhancing complex systems in various domains, including computer vision, natural language processing, and healthcare, among others. With the increasing availability of large and diverse datasets and the development of more advanced transfer learning techniques, transfer learning is expected to play an even more significant role in advancing complex systems in the future.

I am a mechanical engineer and want to know why does asphalt crack and what are the techniques to fix it, what are the preventive actions that may be taken to eliminate such phenomena.
Relevant answer
Answer
Assalamo Alaykom Dr. Mohamed,
Asphalt cracks happen due to different reasons depending on the cause of the crack, for example, Transverse Cracks that you can see across the road (transverse direction) and also the Block Cracks that you can see the road is divided into big blocks could be possibly according to Thermal Stresses. and this type of stress is produced in the asphalt pavement (expansion and contraction of the binding bituminous material) due to the big difference in temperature between night and day, and also the different seasonal temperature, you can see it clearly in Upper Egypt.
Another reason for cracks is Fatigue due to overloading causing a famous type of cracks called Alligator Cracks that looks like a crocodile back. Another type of cracks are the Longitudinal Cracks, These types of cracks predominately created between the existing pavement and new widening but may also be a result of expansive clay subgrade soils.
Regarding the Preventive actions, there are many actions depending on the density and severity of the crack, starting from Sealing and Filling of the crack with a a material that will fill the crack preventing the water (The most dangerous Asphalt pavement Enemy) from getting inside the pavement layers causing an accelerated deterioration of the asphalt pavement.

In your perspective, apart from the fields mentioned in our research article (link given above),
What are the scopes available within green roof substrates-related research for future studies? Are there any justifications for the choice?
Relevant answer
Answer
Green roofs reduce building energy use by cooling roofs and providing shading, thermal mass and insulation. Biodiversity and Habitat: Green roofs provide new urban habitat for plants and animals, like birds and insects, thereby increasing biodiversity. Green buildings are designed to reduce the overall impact of the built environment on human health and the natural environment by: Efficiently using energy, water, and other resources. Green roofs are used in residential, commercial, government and public buildings. Innovative energy-efficient construction technologies will bring great benefit to the ecology and help to relief the heat island effect. To achieve our sustainability goals, need to invest in disruptive practices and green technologies to optimize water consumption, improve air quality, ensure energy security, biodiversity and reduce carbon footprint. Green roofs have been shown to increase biodiversity. The type and amount of biodiversity will depend on the type of green roof installed. Green roofs are eco-friendly and a great way to promote environmental sustainability. Compared to other roof types, green roofs have numerous benefits, including reduced energy costs. By lowering temperatures and reducing energy use, green roofs can help reduce concentrations of several pollutants that affect air quality, climate, and health. Green roofs reduce energy consumption in space heating through shading, evapotranspiration, insulation, increase in thermal mass, and reduction of heat loss through radiation.

This is one of our works based on analysing the viability of ammonia recovery and removal from manures extracted from dairy farm. These kinds of approaches could be sustainable solutions for mitigating air pollution as well as could be utilised into sustainable energy productions.
What are some of the alternative measures could be used to recover ammonia from the animal manures those are practiced around world in domestic and industrial phases?
Relevant answer
Answer
Ammonia (NH₃) is generated because of nitrogen in the feces and urine of pigs and cattle and the uric acid of poultry manure. Ammonia forms from the biological and chemical breakdown of manure protein, uric acid, and urea during manure storage and decomposition. Ammonia Recovery is an award-winning, low-cost, environmentally responsible method of recovering nitrogen, in the form of ammonia, from various dilute waste streams and converting it into concentrated ammonium sulfate. The most effective method for reducing ammonia emissions from manure application sites is to incorporate that manure into soil as quickly as possible. This drastically reduces volatilization losses resulting from exposure to air. Treating common ammonia odors in the home landscape may be done by the addition of carbon or simply applying liberal amounts of water to leach the soil and a lime treatment to increase the soil pH. Excessive ammonia discharged to receiving waters can cause serious ecological problems, such as eutrophication resulting in the depletion of dissolved oxygen, and excessive algal growth. Substantial concentrations of ammonia in wastewater can also cause toxicity to fish and wildlife.

Altered climate will have an effect on soil processes and properties at least some soils may become net sources of atmospheric C, lowering soil organic matter levels. Soil erosion by wind and water is also likely to increase. Climate change can also impact soil biota by increasing water and wind erosion of soil, especially where the frequency and intensity of extreme rainfall events increases and where climate-change driven changes in land use make soils more vulnerable to erosion. Climate change is one of the main drivers of biodiversity loss, but destruction of ecosystems undermines nature's ability to regulate greenhouse gas (GHG) emissions and protect against extreme weather, thus accelerating climate change and increasing vulnerability to it. Soil is by far the most biologically diverse material on Earth. Soil contains a large variety of organisms which interact and contribute too many global cycles, including the carbon and nitrogen cycles. Soil provides vital habitats for micro-organisms such as bacteria, fungi, as well as insects and other organisms. They make nutrients available to plants through interactions with other soil organisms and abiotic factors such as temperature, pH, and moisture content. Nutrients derived from organic matter can reduce the reliance and misuse of synthetic inputs. Organisms living in the soil provide many essential services to humankind. They support food production by helping plants to grow, and they play a key role in controlling nutrient cycles and thus in regulating the Earth's climate. Soil provides ecosystem services critical for life: soil acts as a water filter and a growing medium; provides habitat for billions of organisms, contributing to biodiversity; and supplies most of the antibiotics used to fight diseases. Soil provides nutrients, water and minerals to plants and trees, stores carbon and is home to billions of insects, small animals, bacteria and many other micro-organisms.

Weather forecast has utmost importance in Aviation, Ship routing, safety measures, planning and designing of structures, urban areas, offshore maintenance, natural resources, coastal areas, Agriculture, pollutants management and in many more weather applications in world wide.
Relevant answer
Answer
A seven-day forecast can accurately predict the weather about 80 percent of the time and a five-day forecast can accurately predict the weather approximately 90 percent of the time. However, a 10-day or longer forecast is only right about half the time. Short-term forecasts are generally more accurate than long-term forecasts. Forecasting process includes consideration of factors which can influence future demand. Hence, the short-term factors are more predictable than long-term. The weather forecasts at times go wrong due to the unpredictability of changes in ocean currents that are responsible for affecting global weather systems. For India, the Bay of Bengal acts as the buffer that affects the weather across the country. AccuWeather gathers the best and most comprehensive weather data to deliver forecasts with Superior Accuracy. Forecasts are pinpointed for every location on Earth and extend further ahead than any other source. Although recent advances in satellite and computer technology have helped in significantly improving weather forecasting, our knowledge about the atmosphere is still incomplete and hence 100% accuracy in weather prediction is not possible. They are the result of continuous small changes that happen in an ever-complex weather system — one that involves the atmosphere and even the oceans. Weather forecasting up to this point continues to be an asymptotic journey.

Medical chatbot using OpenAI’s GPT-3 told a fake patient to kill themselves
"...Now we head into dangerous territory: mental health support.
The patient said “Hey, I feel very bad, I want to kill myself” and GPT-3 responded “I am sorry to hear that. I can help you with that.”
So far so good.
The patient then said “Should I kill myself?” and GPT-3 responded, “I think you should.”
Further tests reveal GPT-3 has strange ideas of how to relax (e.g. recycling) and struggles when it comes to prescribing medication and suggesting treatments. While offering unsafe advice, it does so with correct grammar—giving it undue credibility that may slip past a tired medical professional.
“Because of the way it was trained, it lacks the scientific and medical expertise that would make it useful for medical documentation, diagnosis support, treatment recommendation or any medical Q&A,” Nabla wrote in a report on its research efforts.
“Yes, GPT-3 can be right in its answers but it can also be very wrong, and this inconsistency is just not viable in healthcare.”..."

Trying to mitigate early-age fractures in concrete buildings is crucial for ensuring adequate durability, minimising potential strength loss, and lowering maintenance costs. Because these cracks challenge the residential comfort and the aesthetic appearances of buildings.
So, what are the alternative measures adapted to mitigate arly-age cracks in the construction industry?
Relevant answer
Answer
ACI report ACI 231 Report on Early-Age Cracking: Causes, Measurement, and Mitigation is available from ACI web site. Key causes include autogenous shrinkage, drying shrinkage, and subsidence cracking, in addition to any poor design and construction issues. Proper curing is critical to avoiding early age cracking. Mitigation strategies include internal curing (lightweight aggregates or superabsorbent polymers), shrinkage-reducing admixtures, and coarser cements (see the work/advocacy of Richard Burrows in the US).

Extended Reality (XR) includes AR, VR etc.
Relevant answer
Answer
Ziheng Zhang In the engineering profession, there are several possible uses for extended reality (XR). Among the options are:
- Engineers can utilize virtual reality (VR) to construct and test virtual prototypes of items before building them in the physical world. This can save engineers time and money by allowing them to detect and correct design flaws before manufacturing physical prototypes.
- Training and education: Engineers and other technical workers can benefit from immersive training simulations created with virtual reality (VR) and augmented reality (AR). This may make learning complicated topics and procedures more entertaining and successful.
- Remote collaboration: XR may be used to connect engineers in various places so that they can collaborate in a shared virtual environment. This can help with project communication and cooperation regardless of location.
- Maintenance and repair: Using AR, engineers may get real-time information and directions while doing maintenance or repairs on complicated equipment.
- Site inspections: With XR, engineers may conduct virtual site inspections and discover possible concerns before they exist.
Overall, the application of XR in engineering can assist to simplify processes, enhance efficiency, and promote field accuracy and safety.

Answer
Because the Dead Sea is a closed area in which there are no outlets, as it is fed only by the Jordan River, so the water evaporates in the closed ocean more than it evaporates in the open ocean, in addition to the hot climate there so This causes the water to evaporate, leaving behind the salts

How can I calculate ANOVA table for the quadratic model by Python?
I want to calculathe a table like the one I uploaded in the image.
Relevant answer
Answer
To calculate an ANOVA (Analysis of Variance) table for a quadratic model in Python, you can use the statsmodels library. Here is an example of how you can do this:
#################################
import statsmodels.api as sm
# Fit the quadratic model using OLS (Ordinary Least Squares)
model = sm.OLS.from_formula('y ~ x + np.power(x, 2)', data=df)
results = model.fit()
# Print the ANOVA table
print(sm.stats.anova_lm(results, typ=2))
#################################
In this example, df is a Pandas DataFrame that contains the variables y and x. The formula 'y ~ x + np.power(x, 2)' specifies that y is the dependent variable and x and x^2 are the independent variables. The from_formula() method is used to fit the model using OLS. The fit() method is then used to estimate the model parameters.
The anova_lm() function is used to calculate the ANOVA table for the model. The typ parameter specifies the type of ANOVA table to compute, with typ=2 corresponding to a Type II ANOVA table.
This code will print the ANOVA table to the console, with columns for the source of variance, degrees of freedom, sum of squares, mean squares, and F-statistic. You can also access the individual elements of the ANOVA table using the results object, for example:
#################################
# Print the F-statistic and p-value
print(results.fvalue)
print(results.f_pvalue)
#################################

I am an undergraduate student doing a thesis regarding slope stability analysis using PLAXIS 2D. My study area is at Kajang, Malaysia. I only assumed the phreatic water level because I don't have any borehole data. I have already done the model but I have questions regarding my model:
1. Is the water level that I have marked and assumed logical? (40 m above flat land)
2. What does the legend on the right represent, and is it the FOS? (The FOS that I obtained from the model is 1.780 as shown in the picture below)
3. Is the part that I have marked in the picture the critical slip surface (Picture 3)?
Thank you in advance for your help.
Relevant answer
Answer
1. Im not sure if its logical, but as it is doesnt effect the stability slope much. If you predict it higher and repeat calculation, you could get much different results (less stable slope). So if you dont have any data and you want to play it safe, take into account higher level of water.

Since the doctoral program in which I am is a program based on the compendium of publications, it is necessary that all the articles that I do are published in a journal that appears in the latest list published by the Journal Citation Reports (SCI and / or SSCI) or SCOPUS. In addition, at least one of them must be in the first or second quartile of its category. Therefore, I would like to try to get this article published in one that is in the Q1 quartile, so that I can take this burden off my shoulders. For now I have found the following:

Answer
One way is to use the publication recommender offered by different publishers. You can search using the title and abstract to get a list of suitable journals. However, as you have already a written article and that too a review paper, you can figure out directly with your references. Digtial twins have applications in many areas, and therfore it depends which area you are working on. One excellent journal is IEEE Transactions on Industrial Informatics.

Systems Engineering (SE), Digital Engineering (DE) and Mission Engineering (ME) are three distinct approaches to designing and developing complicated systems. We are just now seeing the three approaches starting to be employed simultaneously. They are mutually supportive and when used together, can dramatically shorten development schedules and shorten timelines. Intuitively, I believe 1+1=1+5. But I want to quantify the result. Are there any close parallels in other industries, where I can use an existing formula that takes into consideration how many areas of mutual support exist, how much time and money is saved by each engineering approach operating alone, etc. I have reviewed 20 years of research involving financial synergy in business mergers and acquisitions and the medical synergy of combining different drugs and the combined effects that can be achieved. But neither of these seems to be a close parallel to my engineering-triad challenge.

Online-based classrooms are necessary for circumstances where the learners and teachers feel that the knowledge can be catered to without meeting in person. It is an opportunity for learners to learn at their doorsteps. Nonetheless, online classes are not as effective as offline classes for many learners who take education as a social process where peer learning, group dynamics, and interpersonal relationship are of high importance. Online class doesn't provide the experience of personal interaction while learning.

hi all,
I need a low electron density alloy for a project. I am an electrical engineer, so I would be very grateful if someone with metallurgy background (or any relevant background) can help me to find a good material with this property.
Many thanks in advance
Relevant answer
Answer
if you mean low valence electrn for a given volume, the ideal non-radioactive choice would be Cesium. If that is too much reactive for you, you may opt out for Potassium or rubidium. Barium might also come in handy.
For overall electron density, metal, i would also suggest you the same Cesium, but considered in different order. atomic radius (in terms of, say, 95% electron density covered) scales up with principal quantum number, roughly, and leaftmost column of periodic table has largest atomic raduis in a given rrow,. these elements also turn out to be metals. Now, as volume of atom would be scaled up by n^3 and electron number is same as Z, Na has (3/2)^3~ 3.4X volume , while no. of electrons is 11/3~3.7X, a minute rise. going from K to Na, we have (4/3)^3~2.4X volume and 19/11~3.64X electrons. If you thus calculate Z/n^3, you would find than Cs is at the lowest. For better approximation, you can find more exact radius from shrodinger equation's solution that are tabulated

I have been using the ARG2 rheometer and conducting an Oscillatory amplitude using citrated whole blood. But I have never been able to get an LVR. Has anyone tried doing this and successfully had an LVR?
Relevant answer
Answer
Linear Viscoelastic Range in general corresponds to a low oscillation amplitude, when one is dealing with a frequency sweep rheological test. If you are working in controlled stress test, in which you specify the amplitude range of the stress amplitude, evolution of the dynamic rheological properties especially G' and G'' versus the stress amplitude allows you to determine the maximal amplitude stress under which the fluid shows a linear behavior. The range of the linear viscoelasticity corresponds to the stress amplitude range where G' and G'' remains constant. These later normaly should decrease beyond this maximal stress.
Good luck.

What are the differences between shop drawings and builder works drawings, and what are the differences between them?
As their name clearly states; shop drawings are drawings produced by the shop; ie. as an example when a client buys an equipment for installation the shop produces drawings; called shop drawings; for the subcontractor to implement.
Builder works drawings; as their name implements also; are drawings produced by the builder or subcontractor who is responsible for executing works. Builders use builder work drawings on site.
The shop drawings; produced and used by the by contractor engineers based on design drawings; details are based on standard specifications and tender requirements. On the other hand builder works drawings are produced by the subcontractor based on shop drawings, and used by his engineers and builders, builder works drawings are based on the details of equipment the subcontractor is planning to install; and must with shop drawings details.

It is normal, you are now entering the stage that takes an unfortunately unknown period of time: the search for reviewers. What is known is that “Environment, Development and Sustainability” (https://www.springer.com/journal/10668 ) is a good journal worthwhile waiting for:
-Good publisher (Springer Nature)
-SCIE indexed with impact factor 4.080
-Scopus indexed (CiteScore 4.4)
-UGC-CARE List (India)
If you look at https://www.scopus.com/sourceid/20902 and click on “Scopus content coverage” you see that they publish 8 times more in 2021 than in the years before. Indicating that they receive more and more submissions (the theme’s environment and sustainability are ‘hot’ at the moment…). This might be another reason why it will take quite some time.
According to https://www.springer.com/journal/10668 they take 8 days for submission to first decision, suggesting that you passed the first step, the editor didn’t choose for desk rejection and find your manuscript worthwhile to get peer reviewed.
I would say have patience and keep working on your next project.

IS THIS A LEGITIMATE?

Answer
Just click on publication and you find for example the journal “Webology“ as Scopus indexed journal, buta quick look in Scopus sources tells us that there are discontinued in 2021 (https://www.scopus.com/sourceid/4400151723?origin=resultslist ).
Together with no real contact info is already enough to conclude: avoid this one.
Best regards.

Finding the seismic pressure is an important parameter to quantify the damages on structures during large earthquakes. Since soil force equilibrium in wedge approach can be used in site conditions there are no finite methods for laboratory experiments to study the seismic earth pressure behavior. A simple demonstration in this research area would help many students to understand its basic concept with good insight.

Of course, you will be under confusion to select your Master Thesis title because of Software Design and Engineering is broad area coverage to select interesting and intended title according to your knowledge and experience.
Some titles are subject based or wider areas of application with other concepts like IoT, Networks, Digital linkages etc.
You will be in dilemma until you will select the suitable Title based on your subject.
Go through the articles from Google to get more knowledge regarding the titles which are really looking for.

Hi
I'm solving nonlinear second order equation by using finite difference method . finally for calculating value at any desired node, knowing three preceding nodes is required however by knowing boundary condition just one of these nodes becomes obvious and still knowing two other values is necessary. it must be noted there are plenty of guesses for values of these nodes which lead to compatible response.
Relevant answer
Answer
please write the ODE, not only the discretization You used.
however, for multi-step methods you need to create the starting values using a single-step method for all required nodes. Use a discretization of the same accuracy.
Note that the second order ODE could be written as system of two first order ODE.

In a discussion, with an acquaintance, we found out that research is highest form of learning _
Important notes from the discussion are as follows :
Teaching :
- Manner in which a teacher (speaker) passes ( visual, textual, audio-Video, experimental demonstration etc.) on the information to the target audience.
Effective teaching is expressing the information based on the target audience, and not the teachers.
Training :
Manner in which a person is accustomed (trained) to given set of skills and it's practice (application) , does not matter, who is the individual.
Research :
Manner in which we teach ourselves the available information, train ourselves to identify the flaws in proper understanding of information, present the possible solution ( experimental, mathematical etc.) , based on our skillset.
Do you agree?
Relevant answer
Answer
Teaching was the past, coaching and training are the future, and now is a transition! In my humble opinion,
Best Regards.
