Engineering - Science topic

Dear Baskhar,

P.K. Karmakar Thank you for the encouragement! Before offering my opinion I will offer a disclaimer-- the deepest understanding I have of theoretical physics research comes from a recent reading of Neil deGrasse Tyson's "Accessory to War" (while not a technical read, I highly recommend it). The book offers an interesting insight: while theoretical physicists tend to be opposed to war, their research outcomes are often first utilized by military before reaching civilian markets. To speculate on Tyson's offering: I think generally, direct commercialization is challenging. While outcomes of theoretical physics research have a multitude of application (in warfare and civilian markets), I imagine large scale development is initially very costly (due to being highly technical in nature). Military budgets, being extensive and widely unchecked, allow for far more spending on prototyping/developing these technologies than what civilian industry can achieve. I suspect many outcomes of theoretical physics research undergo initial development in a military setting, later transitioning to civilian markets after this process has reduced development costs for businesses. That said, I am sure there are exceptions-- I am just unfamiliar with them. I hope my answer is helpful. If you know of any cases of outcomes going from lab to civilian markets, please do not hesitate to share. I would love to learn more about direct commercialization of theoretical physics research! Thanks again for your comments.

Dear Saad Sarsam .. thanks for your answer..

Actually, mt question is on special case, .. concreting on summer time, .. with most higher temperature degree...

One should be careful to compare the design, sizing and performance of tiny lab/bench scale (EGSB) reactors operating in steady optimal conditions with that of industrial full-scale reactors operating in real world varying conditions on real wastewaters with continuously changing composition and loads.

EGSB = Expanded Granular Sludge Bed reactors require granular sludge to operate at high upflow velocities. In most real world cases, especially on high protein wastewaters (whey, lactoserum), the high-rate upflow reactors operate on a mix of granular and flocculating sludge requiring a well designed UASB/EGSB with adjustable reflux and full process controls as recommended.

Hello,

I have written simple 1D drift-diffusion solver examples using finite difference and Scharfetter-Gummel discretization which you can find here:

I'm happy to answer any questions.

hope this link is useful

ok share it with us if we can help

Maybe you can find something here:

Grouting inside tendon ducts after pre-stressing operation

protects tendon from possible corrosion .

helps in maintaining pre-stress force reducing losses.

protects structure from sudden failure, if local damage takes place for tendon.

Science exists since the day on which universe was created. We may have found the answers to many questions related to science later. But it does not mean that it was not there before. In 1687, Newton presented his theory of universal gravitation and three laws of motion. Does it mean that law of gravity didn't exist before it was demonstrated by Newton?

Science is investigated but technology is created. In the words of Albert Einstein, “Scientists investigate that which already is; engineers create that which has never been.”

Everything can be explained by science. We have not created science, it was there before us and before everything. As per Collins English dictionary, "Technology refers to methods, systems, and devices which are the result of scientific knowledge being used for practical purposes".

So, application of science to develop new devices, systems or methods is called technology.

Thanks .. .... for your answer

There are quite a few methodologies: in Croatian research we often use WEF methodology. I find GEM appeoach very interesting.

There can be negative citations too.

You can derive hypothesis from your problem statement or the objectives of the study. so let me know what your objectives and problem statements are then i can help you.

This also depends on the field and the discipline‘s accreditation rules. In Nursing, there weren’t many doctoral programs until the last 10-15 years. The masters degree was the terminal degree, therefore all masters students were taught by masters faculty.

Now we have doctoral programs, but masters degreed faculty are still allowed to teach masters students if the school of nursing cannot hire enough doctoral prepared faculty. I taught masters students with a masters degree for several years before obtaining my PhD. As several of you have pointed out, the experience of the teacher counts too.

The world has currently reached the peak of its development in all fields. However, there is a growing fear of the risks that war between the super powers may erupt if so extreme or irrational people assume power and take decisions that may lead to the destruction of human civilization. Despite all this fear, we look forward to the prevailing of stability and peace all over the world.

Sure, the effect is volumetric and dimension.

The major job description of a construction manager are:

1) Schedule the project in logical steps and budget time required to meet deadlines.

2) Determine labor requirements and dispatch workers to construction sites.

3) Inspect and review projects to monitor compliance with building and safety codes, and other regulations.

Therefore, the construction manager is in no way expected to preempt the responsibilities of other professionals attached to the project.

Agree.. why not, it 's perhaps it gives more exposure and view in many areas.

I wish you success and I advise you to follow a deep research to result in high quality outcomes for publication. Only this

Dear Mr Nassar,

I recommend you to read the website http://mgsu.ru/en/

Best regards, professor Khomenko

A very wide field of technologies in a variety of sectors, indeed. For example chemical science and industry. See:

Please have a look at these useful RG links.

We need 4 elements: 1. body, 2. counterbody, 3. interfacial medium, and 4. environment medium. For example, humidity affects significantly the Friction behavior of ceramics and polymers. Regards.

Dear, Amit

We can not interact with outer world completely in absence of anyone.

Same way what are five crucial things by which science is speaking with universe.

Fruitful research means that the research has already been completed. What about new research ideas?

I envision the following in the near future:

Thank you for your comments and advice

Hi Alex,

Try checking with with Adam A. Pepi . He has some some work measuring leaf toughness.

Good luck,

Fuel Octane number for gasoline fuel or SI engine's application. The Octane number refer to Ignition quality of the fuel. Normally Octane number varies from 90 to 120 sometimes minimum 95. For Stoichiometric application Octane number 95 would be enough. Two high Octane number could affect on NOx emissions.

Dear Masoud Zamani , please be more honest with yourself and also with other colleagues. This platform is for scientific contribution. You will learn a lot here, even if the experts’ comments are negative. unfortunately, the question has been changed.

wish you good luck..

Hi Mr. Nizamudeen

If you want to investigate the effect of adding GPUs to multi-core CPUs, you can simulation with Ansys Fluent, which you can compare these two facilities with each other.

ANSYS has a good Multiphysics capabilities. I did a structural-thermal-electrical analysis in conjunction with CDF analysis. However I don't know much about electro magnetic simulation. A few Multiphysics elements are available in WB that you can have degrees of freedom in different physics. In addition to that, there is methode called "Load Transfer" that you can you use. Basically you Perform a simulation in a physic and then transfer the result to another physic. You need to identify which method is the best in your application based on a lot of parameters such as complexity, computational resources, time and etc. Hope this information helps.

Sometimes deleting Temp folder affect the performance of other software installed on the computer or reset them to the original state. I suggest to delete only ANSYS files temporary folder that sits at this location.

C:\Users\"Your User Name""\AppData\Roaming\Ansys

Deleting this folder reset ansys to a fresh installed state. Hope that helps.

Our Civil Engineering programme started since last year a fully PBL curriculum. Each semester we collaborate with real clients (Municipalities, companies, etc.) who provide a real complex problem to solve. Students must develop an innovative solution and to present it in various phases to clients and lecturers. All the theoretical knowledge provided is used within the project. The design approach is based on research principles. We have a very positive experience so far. Students are very involved and they seem developing a deeper understanding of the topics when they apply them to real case studies. We measured also a substantial increase in their satisfaction towards our study programme. Without any doubt, the PBL curriculum is working for us.

Dear Dauda,

where do you want to include it? Do you want to include it in your contribution list of the research gate?

If so, go to your profile page you will find a blue switch at the upermost right of the page named ADD NEW RESEARCH + press this switch and follow the instructions to add your article.

Best wishes

With my best wishes for success

Dear Qinglei!

Sorry for not seeing your question before now. I am not a very experienced user of ResearchGate...

Answer: Shifting control modes has (to my knowledge) not been considered within the CIGRE activities regarding designing the test grid.

Albert Einstein: The definition of insanity is doing the same thing over and over and expecting different results.

Since control system is prevalent in everywhere naturally, best approach is to show the real life examples to students and make them understand how control system is the key for stability of the universe, For example, we making sure of the right temperature of water before shower, etc.

When we talk about control system, stability is key concept. So, once the appreciation of real life day to day activitiy is made, then slowly the context can then be moved into more technical examples. Then maths can be introduced to explain various concepts and how stability is ensured for various control theory, such as while designing a controller.

When I studied control systems for the first time, i got overwhelmed with theories. It was only after many many years, everything just started to make so much sense and thus found control systems a fascinating topic.

The answer of Games is satisfactory but i would like to say that Arduino is a microcontroller development board that has interfaces and data converters. It cab be also connected a labtop and PCs. There a wealth of microcontrollers from many vendors including Atmel of Arduino. A microcontrollers is a microcomputer on a chip while a CPU is a central processing unit that needs a memory and input output units to work as a computing platform. Microcontollers are thought for control tasks. You have only to use the proper microcontrollers. If the microcontroller can not perform the tasks you can use one board computers such as Rasperry Pi.

Best wishes

Regardless of choosing laptops or PC, if you load the CPU 100% for two days, it will definitely affect the performance later on. You can check the maximum temperature of your CPU while it is running at 100% and follow the manufacture guideline.

I did this before and it was harmful to my computer :(.

In addition to the answers above... basically, the effective cross-sectional area carrying the load decreases with the movement of dislocations (i.e. plastic deformation).

as far as I know, yes

The aim of "Techniques de l'ingénieur" is to provide a good level validated synthesis of knowledege about very different technical subjects. It is not especially designed for researchers, but for people who want to know the most important data about a pecular subject. The main trouble might be that updates are not very frequent. I have written articles articles in "Techniques de l'ingénieur" and I have never been asked to update them.

Dear Sir Gary Holness , I am feeling very sorry for this authorship claim. But I want you to believe that this is not a fraud but it is a wrong click in a hurry on the 'Recommendations'. And I declare that I am not your co-author.

I want to say sorry again for all this.

For lighting, I think the best software is DIALux.

Search "DIALux" to find the official site and download the software.

I kjnow that exists DIALux EVO to, ut I never used this one.

Dear madam,

As a electrical engineer on which factors i can concentrate to add the new features to existing 3d printer other than mechanical aspects.

5) As scholars, we represent the voice of reason and civility. This is not like some other type of social media platform where people come to troll or hide behind anonymity to say less desirable things.

6) Whatever you put on here is a form of intellectual footprint. “We have not come to curse the darkness but to light the candle of hope” – to use the words of President Kennedy. Let us be supportive, render courtesy to each other, promote peace and freedom (Lehrfreiheit and Lernfreiheit) and most importantly, let us be eager to learn in humility because we are ever discovering how much we don’t know. Let’s try to keep the highest standards of professionalism and brotherhood/sisterhood in a world that has become so divisive and polarized.

7) Here, castes dissolve and sense of superiority due to one’s financial situation or country of origin doesn’t matter. Each one is a mere mortal trying to earn a living and at the same time doing their bit to contribute to the global sustainability. What counts is how much you are able to give to this community and the world, not how much you can gain. We can always report extreme cases to RG.

This is my little contribution to your question.

Dear Hiral Vora,

I suggest you to see links and attached file in topic.

Please refer to the following books:

1. Geopolymer, Green Chemistry and Sustainable Development Solutions by Joseph Davidovits . Please refer to page 136. You can find the book at google book.

2. Concrete Construction Engineering Handbook by Edward G. Nawy . Please refer to page 26-10. You can find the book at google book.

Hope this will help.

Thank you. @ Ali, I do not have a specific discipline as yet. I am currently researching ideas for the proposal.

It is a very interested question

Interested

... One more comment, Rudi. A facilitator acts on two orthogonal dimensions question (Q) and solution (S). In "steady state" the facilitator keeps staying in the Q, asking questions and by doing so facilitating the audience to reflect, solve issues and provide answers with no external intervention. In the case the audience asks the facilitator for his/her opinion on a specific issue then the facilitator may switch momentary to S and then returning to Q. Staying in Q is exactly what you call "being neutral".

I tend to agree with Dr. Garry. During manufacture every 10th product should be tested by a competent technician, inflating the balloons to the recommended volume and seeing that they hold the air for a few hours.

Prior to actual use in surgery, the surgeon should make sure that he/she repeats the testing. Only this time it will only be for a few minutes. And it always pays to have a back-up Pruitt-Inahara shunt in the room.

interesting question

All is right, but currently the combustion engine is the main source of pollutio: ozone, CO2, NO, SO2 and others.

may be the cells hidrogeno can be a future solution.

You can consider two parameters:

1) the mass flow rate, if it is taken constant an increase in the diameter causes a diminishing averaged velocity.

2) the Reynolds number, if the averaged velocity is taken constant the Re number increases. From 0.20 to 0.25 you are increasing the 25% and the Re number can be such that transition to turbulence can occur,

The answer above is incorrect....firstly the overall flow through a carotid shunt is quite small,and secondly,it is only performing the job of the native artery,bypassing it whilst the carotid is clamped and operated upon.

The real issues with carotid shunts are as follows:

1.Decision making process in inserting a shunt may take time,and in some cases may be incorrect,thus relying on good perioperative techniques for measuring or quantifying adequate cerebral blood flow such as TCD and INVOS.

2.Inserting the shunt into the carotid artery can result in dislodging plaque material distally during insertion,or occasionally dissection.

3.The shunt can be placed too far down into the common carotid,and may enter the subclavian origin and occlude flow to the arm,or lose flow through the shunt.

4.The shunt can be dislodged or blown out of the artery,neccesitating reclamping and replacement,with all of the above risk factors.

5.The shunt can interfere with visualising the operation site and may impede surgery to a small degree.

In short,if there is a lack of adequate monitoring of cerebral perfusion,a shunt can be thought of as mandatory by many,but if there is reliable and validated cerebral monitoring(such as INVOS or TCD),then shunting should only be performed where indicated.

Hope that helps.

E-society is a society that consists of one or more e-Communities involved in the areas from e-Government, e-Democracy, and e-Business to e-Learning and e-Health, that use information and communication technologies (ICT) in order to achieve a common interests and goals.

The first areas of e-society that emerged were e-Learning and e-Business.

The development of e-Society is relying and depending on the development of virtual reality (VR) technologies that insure interaction between participants of an e-Society in a more acceptable and tangible way.

The development of (VR) and consequently the e-Society is based on improvement and balancing of participants’ interaction methods, hardware necessary for such interaction, content presentation and effort required for development and maintenance.

Thank you Abdelhalim.... :-)

You are very brave! But too much is too much

Dear Juan,

This is a question with a widely answers. You're talking about a lot of disciplines inside engineering. I imagine you need to focus in one area of interesting. For example: State of the art in Spacial Engineering, etc.

Because engineering is applied in a widely things. As Washin said.

Dear Dr. James

I have sent you a message

This will quite helpful, I think so:

This is a very good question.

In my opinion, the whole process "of conducting research, publishing it, and citing" is moving towards being more politicized. They may call it globalization but, apparently, this is a sort of colonization in which research endeavor in certain areas cannot progress unless it follows the lead of specific groups in other "far" countries. This way, the "masters" can be sure that they stay at the top while the others lag behind.

The story is much longer with many details... a good follow-up is required for writing a "review" or a "book" on this subject & the researcher can support it with statistics & figures.

Ahmed,

Would it have been this?

It's a wireless 'wand' that appears to have sense both its attitude (easy) and location (hard!)

yes possible

For an increased diameter and constant pressure, the volume flow of your fluid should be increased significantly. This is actually quite easy to calculate for newtonian fluids. However, as you describe your fluid as "glue", it may have all sorts of strange properties.

These few tutorials and links may help you in this

it is easy by using statistical fitting
