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.

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.

Suppose at 8:00 AM solar intensity is 350W/m2. Can we find out intensity for 9:00 AM with any formula?

Yes, you have to define a multi-phase model, e.g., VOF or Euler-Euler.

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.

Hi Joseph C Lee

I agree with you that it depends on the editor and reviewer. However, could it be better to display this factor (in average or estimated value) on the journal's website. So that authors can get a rough estimate for article.

"...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.”..."

We do not dig deep enough. The answers are superficial. Human culture in general is violent towards society and nature. Existing rules of our economic game are flawed. As long as we stick to the money and capitalization as the measuring rods of our "success" and "productivity" in privately closed entities, no satisfactory result can be expected. Let us try to understand the deep meaning of the global interdependence and the common good.

Hi,

I suggest you see the links and attached file on the topic.

Best regards

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).

Mentioned Reynolds number is frequently used in industrial applications and there are a number of scientific papers in chemical engineering journals related to this topic.

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.

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

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 hope that helps

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.

Questions 2 and 3 were already answered by others.

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.

Revered Professor Sivakumar Pushparaj,

One can find out the particular Journals are Scopus Indexed one or not.

There are platforms these Journals title have to be included to check it whether the Journal is Scopus Indexed or not.

www.scimgo.org is mostly used to check the Scopus Indexed Journals status because the Scopus status will be removed if the performance of the Journals are not up to the International standard of research outputs to satisfy the academic and research community.

There are many hyper links will help to know that whether the Journal is Scopus Indexed or not.

They have some expert lectures on that so people can take advantage of that as well.

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.

I can suggest that you look at the questions posed by the circular economy. Below you will find some documents considering this issue from the occupational health and safety side, but the initial approach to this issue in these articles is much more general

The type of University would hardly matter if your Ph.D. topic is unique and work is free from any synonym of copy and you have followed the standard norms like publishing min three papers in Scopus Indexed journals and patenting your work etc. Ultimately the doctorate person will be judged not on his face vale but on the basis of his knowledge and work.

In my opinion, it is dominated the bibliography in research paper meanwhile the data in the technical paper.

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

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.

Zhwan Sktani congratulations. I am also a CEng member of the IMechE. Seen this post albeit a little late and wondered if I could be any assistance.

Mathematically, the answer to the equation is zero; the answer Python spat out is pretty much as close as you can get to the representation of zero with a typical computer.

This is a classic floating point problem: https://en.wikipedia.org/wiki/Floating-point_error_mitigation

A builder work drawings will provide in detail the component representation and client communication of what the engineer designed. Contrarily, shop drawings is for fabricators and technician use only and it is basically for determining how components will be produced and placed during the construction process.

Thanks a lot!

According my experience, TRNSYS is the best and most accurate but remains more complicated in order to master the simulation process. Otherwise, energyplus is easy with reliable results.

Hello, again, Shuraik Kader (it has been a long time since you heard from me)

I agree with Rob Keller that this length of time is very long. And, unfortunately, it is longer in some journals than others. That variation depends on the journal (how long it takes for the editor and the staff - what they are like) and depends a bit on your article (if it is a topic that it is very hard to find reviewers for). My advice is to be patient - we authors always want the results faster… If you are bored with waiting I suggest you can start work on your next project/paper…!

Dear Tao Li,

Your observation is very apt. Most of the time the academic articles may not contain adequate details for clear understanding. In such cases you should make you of cited articles to go down to the fundamental/original research works for better clarity. Books are better source for understanding how the methods and formulas are derived from scratch.

Dear Shuraik Kader,

In view of the increasing risk of an energy and climate crisis, eco-innovation-based, green building technologies will be developed in the future to build homes that are significantly more energy-efficient and resistant to the negative effects of climate change. Consequently, the future will mainly develop pro-environmental, energy-efficient sustainable construction. Perhaps it will also be environmentally neutral construction based solely on natural building materials.

Best regards,

Dariusz

Dear Jehad M Yousef ,

Short answer no. They have been discussed here on RG: https://www.researchgate.net/post/Are_the_conferences_organized_by_IIRST_and_ITAR_authentic

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.

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.

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.

Invariably the loading on one storey building roof with access is only `1.5 to 2 kN/m2 . and this is uni-formally distributed load. But if you pile up load in a small area more than the failure load of slab with concentrated load then the failure is imminent. this failure load can be calculated using yield line theory or by Hillerborg Strip method.

If you have this kind of loading then keep your props intact before you finish roof top work

Dear Brian Clause,

I'd like to give it a try and answer your question. Before I get to the point, it is important to emphasize that mechanical impedance is a complex quantity that provides the relationship between the velocity response and the force input of a linear system in the frequency domain.

Therefore, if we suppose an 'ideal damper' (with no inertia and stiffness effects), we realize that the corresponding mechanical impedance is given by the damping coefficient. Physically, it means that the damping force is in phase with velocity, and thus an ideal damper is a resistive element that dissipates energy.

However, for real systems in which inertia and stiffness effects must be taken into account, we conclude that the corresponding mechanical impedance is given by terms related to inertia, stiffness and damping of the system.

I've also attached a file from Prof. Mike Brennan if you want to search for more information about this topic. If you want to go deeper, check the reference below:

Dear Malini Kanapathy, you have to separate the two compound for accurate analysis. After that, the polymer and the carbon compound are subjected to characterization. These include, NMR, elemental analysis, FT-IR, viscometry/GPC, DSC, and so on. My Regards

Participated in the questionnaire survey, Asharf. Good Luck and best wishes for your thesis and letting me know your email address and so, I can also share the questionnaire that I will develop to you via emails for the data collection, Ashraf Elhendawi .

Apart from suggestion received, you can study the SUN DIAGRAM for our location and according plan your design of rooms. Requirement of rooms need to be workout before you proceeds for planning. Architectural planning concepts need to adhere for better planning with respect to your requirement.

The same concerns will be shared here which means I agree. The supposed standard concept of ethical publishing and research were taught and still in practice. Direct communication to the author/ correspondent is necessary, and in this way, limited access or limited amount of the manuscript maybe shared, both parties protected, and continuum of knowledge is not compromise. Best wishes.@Mahamid

sometimes having a small pumping station for the high lat customers is beneficial.

You don't say the reasons why reviewers rejected your article. Even if you are not satisfied with their comments, it is advisable to correct your article according to the recommendations of the reviewers because you do not hold the truth or part of the truth.

If you give the exact reasons for the rejection, the readers of this platform can help you improve the quality of your article and give you the right advice.

Perhaps using a quantum model.

Instead of a proposition of which to say whether it is true or false and to decide which branch to take, a quantum state function that precipitates with a measurement process into one of the component eigenstates and determines which case of a case statement is chosen.

The quantum computer could help.

Dear Claudio Calovi Pereira ,

Yes, there should be a classification as "Architecture" seperately. Otherwise, the categorization would be placed in either engineering/ civil engineering/ construction or building acoustics, where there is little chances for readers to have a review on the specific articles in Architecture.

"What would happen . . .?"

A mature system would reset resp. enter some safe state (in the worst case once the maximum allowable execution time has been exceeded).

Any other system might ruin your day or blow-up the world :(

Yingxu Wang The primary distinction between Level 3 and Level 4 automation is that Level 4 vehicles can act if something goes wrong or if the system fails. In this way, most of the time, these automobiles do not require human engagement. However, a person may still manually override the system.

Yingxu Wang Because all software systems have quality features such as availability, modifiability, performance, security and safety, testability, and usability, basic software principles give common methods or techniques to support those qualities.

Developing an accurate "Time Remaining" indication for downloads, backups, software installation, battery life, and other tasks is by far the most difficult job in computer science. Despite being a persistent cause of anger and shame, little progress has been made on this issue in decades.

Dear Shuraik Kader,

Given Albert Einstein's theory of relativity, cosmology regarding the development of the universe, quantum mechanics, future technologies for building interplanetary spacecraft, etc., time travel is theoretically possible. But in practice the building of a time machine by humans is impossible. Even if a man would achieve the required technological development in the next several hundred years, unfortunately he would not have enough time for it. First of all, a person must first solve other global problems, such as the necessary one is urgent, i.e. in the perspective of the next max. 2-3 decades of time, stopping or significantly slowing down the progressing global warming process, achieving zero-emission economy and avoiding a global climate catastrophe, which may occur at the end of the current 21st century. In order for man to be able to create new technologies of the future, to be able to build interplanetary manned spacecraft, etc., he must first save the planet's climate, biosphere and biodiversity from the risk of almost total degradation.

Best regards,

Dariusz

The simple muiltiplication of the mass by the thermal capacity as Bachir Achour proposes, is valid only at thermal equilibrium. Since buildings are always in a thermally dynamic state, this method strongly overestimente the active thermla capacity. When the ambient temperature continuously changes, the calculation is more complex, and needs solving the equation of heat. Simple mathematical solutions to determine the thermal mass of a multilayer plane building component under dynamic conditions are indeed described in EN-ISO 13786 as mentioned by Edwin Rodriguez-Ubinas.

An experimental method to determine the dynamic thermal capacity of a room was proposed by Van der Maas (see attched paper). The apparent room effusivity can be measured by recording the increase of the indoor temperature after switching on a constant power heat source.

Dear Bassel Hossam Eldin,
