Hello Research Gate Community!
I am a first year Entrepreneurship Ph.D. student at Baylor and I am conducting a study on academic scientist’s intention to commercialize their research.
While a lot has been done on the topic of commercializing research, almost no one has examined it from the perspective of the scientist. Your perceptions of research commercialization matter and should be considered by university policy makers when designing the process.
I don’t think anyone likes long surveys and I know you have much more important things to do, so I designed the survey to take less than 10 minutes. If you are willing to take the survey, you can access it through the link below:
Thank you very much for the time and consideration!
I am developing a shell element model for a concrete bridge. I am currently at a stage of assigning the traffic lane UDL.
As you can see in Figure 1, the traffic lanes are unfortunately at a angle (not 90 degrees) with respect to the horizontal direction, in other words, are not in parallel with the bridge span direction.
My model is shown in Figure 2. It is already been meshed.
Can someone please give me some hints on selecting the elements that are under the traffic lanes; hence I can apply required UDL on them?
if the lanes had been perpendicular to the horizontal, I would have used NSEL,S, LOC,Z,(elevation of bridge deck) and NEL,R,LOC,Y, (coordinate of the left and right boundary of the lane), to select the elements. However, it's been difficult when the angle is not 90.
That was the major question when I visit marine structure... where the engineer need to know the scientific reason for don't using sulphate-resisting cement not used in marine concrete?
From the question that commonly asked by engineers during casting concrete that can we neglect the expansion joints, if the construction of concrete is carried out in summer?
Im chemical enginI am a chemical engineer and my research project is the production of biogas with whey. And my work is in the first phase a proyect i work is biogas production whit lacto serum and the proyect is in a first phase
I have a set of coupled ODEs:
J = mu*e*n(x)*E(x) + mu*K*T0* dn(x)/dx
dE(x)/dx = (e/eps)*[N_D(x) - n(x)]
These are the drift diffusion equation and Gauss's law for a unipolar N+ N N+ device. The doping profile N_D(x), the mobility mu, T0 are known. The DC current, J, is also known, as are the boundary values: n(0) = N+, N(L) = N+. I want to self consistently solve the above two equations using finite differences, but I am unsure how to go about doing so.
Thanks in advance!
Mathematical modeling is becoming a prominent factor in almost every field of Engineering along with simulation and modelling. The research becomes more viable but complex and to understand. Please state your comment and observations.
I am student of Master in Information Engineering. The software architecture domain is new for me. I want to do thesis in it. I am thinking to do in "security for software architecture" but I still have to narrow down or may be from where to start I am very confuse. Any one could help me please.
I am a student researching on morphing wing, does anybody know where/how should I start my research, for I have tried to find some related articles or books but have come up short. Thank you in advance for any help.
Whom concern with prestressing works, always asked about the function of using grouting inside tendon ducts....
Science and technology are complementary to each other. The ancient humans developed technologies to survive in earth through different raw materials and tools. They didn't understand the science behind those things. No research was conducted. Everything was generated by trial and error method. Even the animals also go on the same path. I am seeking a constructive discussion regarding arrival of science and technology in human civilization. Which came first?
For marine piles, there are several options available for selection, namely H-piles, circular pipes and box piles. However, only circular piles and box piles are suitable for marine application... why?
The development of innovation is currently one of the key production factors in developed economies.
In recent years, developed economies have created many technological, process, product, service, marketing, ecological, material and other innovations.
In some countries cooperation programs for research and R & D centers with enterprises are being developed to activate entrepreneurship and innovation of business entities.
Because in developed countries information, innovations, new technologies and entrepreneurship are considered as one of the most important factors of the country's economic development and, as a consequence, also economic growth measured, for example, by the Gross Domestic Product in subsequent years.
In addition, research and implementation works are conducted in these themes, which further underline the high level of significance of innovation, new technologies and entrepreneurship in contemporary national economies.
Clusters are created within which enterprises undertake cooperation with other business entities, with scientific, research and implementation centers, universities, public sector institutions to exchange experiences, transfer knowledge, run and develop joint research and implementation projects, including innovative technological and process solutions , research, organizational and other.
However, in order to be able to objectively verify the effectiveness of these programs to activate the level of innovation, it is necessary to periodically perform a precise measurement of changes in the level of innovation in geographical, local, national, in relation to individual departments, sectors of the national economy or by examining specific types of business entities, companies and corporations.
Because innovation is determinant of economic development of a qualitative nature, it is difficult to measure.
In connection with the above, I would like to ask you the following question: How is the level of innovation most often measured in your country?
Are they carried out periodically, eg surveys among management, among managers of companies and corporations, or other methods, are periodical changes in the level of innovation in specific types of business entities or in individual sectors of the national economy?
Do you have specific quantitative measures developed that can be helpful in measuring innovation?
Please, answer, comments. I invite you to the discussion.
There are many fake journals that you can pay and then they publish your research even it is not worth to be published. So there are many fake citations for some research works. Also there are published papers with a team of authors that they have a pact to put their name in each other's papers even they don't have any idea about the subject of the paper. It means they cite many irrelevant papers to a research. That's sometimes one cannot trust these citations criterias. Ofc there are high quality journals too. But in general could we say a research is high qualified based on its citations number? What's your suggestion to distinguish a good research from a bad research?

For my master thesis, I am working on Mobile Laser Scanner data which my duty is Extraction of Powerlines Poles. My data is about 10 Kilometers long and has approximately 60 the powerline poles. Fortunately, my algorithm has extracted 58 the poles correctly and two others poles were not completely extracted by Mobile Laser Scanner system which caused proposed algorithm can not extract them. The proposed algorithm is completely automatic and does not need many parameters for extraction.
My main question is that which circumstances do need my implementation to be published in a good ISI journal?

After manuscript acceptance, a quick publication is desired but some journals take as much as a year before publishing accepted manuscript without providing early view option. This can be frustrating after the arduous review process. What are the ethical options for handling delayed publication of accepted manuscripts?
I want to know how the practicing Engineers are calculating in the field to design a Concrete pavement on this cross section of pavement.
I am trying to measure the toughness of leaves. I have rigged up a system where I put a leaf on a cube of agar (15g agar per liter water) and drop an empty syringe with a piece of wire (not a needle) through a tube to puncture the leaf. Unfortunately, the weight of the empty syringe is sufficient to penetrate the leaf so I figured a tougher leaf would cause the wire to enter the agar less, thus making a shallower hole. Is there an equation to relate the force required to puncture the leaf to the amount of slowing the leaf exerts on the wire? I also don't know if the difference will be perceptible and perhaps I should find a lighter puncture object
I am looking for literature to aid me with the explanation and discussion of experimental results (saturated pool boiling of water at atmospheric pressure on copper surfaces) where a shift of the boiling curve towards lower superheats and a decrease of CHF were recorded; this trend was noted after the first onset of CHF. I am interested in literature that deals with the change of both the boiling process and surface characteristics (wettability, topography, chemistry etc.) after the first onset of CHF. Also, any literature about the (possible) shift of the boiling curve in repeated experiments on the same surface (as a consequence of CHF onset and transition to film boiling, where possible low-temperature annealing occurs) would be most welcome. So far, a search lasting several hours yielded no results.
"An engine requires the highest fuel octane number when operating at stoichiometric conditions. Lower octane can be tolerated when the engine is running rich." taken from Engineering Fundamentals of the Internal Combustion Engine (Willard W. Pulkrabek) Book
This sentence is true? When operating at stoichiometric conditions, possibility of knocking is lower, so it is not necessary to use the highest fuel octane number.
I think If an engine runs at richer or leaner conditions, higher octane number is required due to lower flame speed.?
The advent of general purpose computing on GPUs makes it important to understand when GPUs are preferable to conventional, multicore CPUs. As new parallel computing platforms such as GPUs and multicore CPUs have come to dominate the market, it also becomes important to revisit parallel programming models and to find the best balance between programming convenience and hardware implementation costs.
How can you investigate application of GPUs to accelerate existing bespoke CFD solvers that has been developed and to benchmark its performance to solve complex fluid flow problems?
I want to evaluate a multiphysics fluid pump problem. This is a conceptual fuel pump for automotive application. The current model has magnetic elements (in pump itself), reciprocating components and an integrated BLDC motor. Architecture of this pump is considerably different from existing reciprocating and rotary pumps. I hope to find some vital information like delivery pressure and flow rate fluctuation, net heat generation, flow pattern inside the pump, dynamics of the moving components etc.
I am a Product Development Engineer and have very little knowledge of CFD or FEM. I am looking for suggestions on,
1. How to move forward with this project ?
2. Do I need a team and different softwares to solve different problems or it is possible to evaluate them by one person?
3. Which kind of softwares are being used to address similar problems.
I will be more than happy to share any more information regarding the project to help you resolve my query.

nice to meet you here. i am an engineer in sgcc in china, and i am very interested in the control system in a dc grid.
in an island wind farm, normally we consider a vf control in a mmc. however, this ac system connected to a ac system. and this mmc could shift to pq control.
have you consider the online shift of the control mode?
thank you very much to read my question.
Your recommendations, guidelines based on your wealth of experience in automation/robotics/control system would be highly appreciated. Useful materials/links for engineering applications are welcome...
My opinion is to use the old computer CPUs like Pantium 2~4 CPUs , Probably t are cheep, and simply wired than the new electronic materials, AS a chemical engineer may be facing difficulties in electronics but its goal. I learnt that the Micro Controller Should be equipped with crystal oscillator its my starting point

Engineering stress strain curve show a decreasing trend after yield point. How can we estimate the mechanical properties?
We want to conduct a survey asking participants to rank a set of 10 fundamental engineering concepts. Ranking a concept 1 would mean the participant believes this concept is the most important engineering concept for an engineer to know, while a ranking of 10 would mean the concept is of least importance.
If roughly half the participants are practicing engineers and the other half are engineering instructors, we would like to know the extent to which these groups might differ in their overall rankings. That is to say, we don't just want to know how these groups differ in their ranking of each individual concept, but rather how one groups aggregated ranked list differs from the others. What would be an appropriate statistical measure for such a comparison?
Is it a decent place to do research or simply a waste of money? Thanks!
An individual named Piyush Sharma from Meerut Institute of Engineering is fraudulently claiming co-authorship on my work. I have messaged him and also reported him to Research Gate. He is not my co-author and has not done any of the work he is claiming. He has the same name as my collaborator.

A facilitator is someone who engages in facilitation—any activity that makes a social process easy or easier. A facilitator often helps a group of people to understand their common objectives and assists them to plan how to achieve these objectives; in doing so, the facilitator remains "neutral", meaning he/she does not take a particular position in the discussion. Some facilitator tools will try to assist the group in achieving a consensus on any disagreements that preexist or emerge in the meeting so that it has a strong basis for future action. (Wikiped)

Technology since Industrial Revolution have made significant contributions to Humanity and at the same time to Environment.
Two nozzles of different output diameters (0.20 mm and 0.25 mm) are being used to take mass measurements for an analysis over a time period for the same input pressure.
It has been observed that the standard deviation in the measurements increases in with an increase in diameter of the nozzle.
Is this true? Does an increase in diameter causes greater fluctuations in the flow for the same input pressure?
What are the problems encountered with carotid shunts that are used in carotid endarterectomy and their possible solutions?
If we talk about the necessity of equipping contemporary engineers, functioning in the “Industry 4.0” and/or creating for the members of “e-society” practical conditions of being and acting and also equipping non-engineers in a (which one?) set of technical knowledge and competencies, the evident problem appears: is there a balance between the amount of non-technical knowledge and competencies of an engineer and the amount of technical knowledge and competencies of non-engineers if we expect the our “e-world” will function properly (according to expectations)?

I researched two highly cited journals publications (2017-2018) and observed that more than 55% papers on very specific research topics are published by 13 research groups from 5 countries. Is really only 13 research groups are capable for the highly cited research load of the world?
Hello, I have watched a video on Youtube about using a method for getting the 3D coordinates of a 3D blade. The engineer used a sensor and touched the blades surface by it and it was transferred to solidworks....Any help to know this method?
Occluded hydrogen has proven effective to remove the CO that anchor on the metal surface. This has been done on Palladium metal. One of the problems is that the treatment with hydrogen distror and ultimately destroy the metallic matrix. Thus, the non-poisoning effect is loss. However, palladium alloys does not suffer such distortion. No wonder palladium alloys electrocatalyst has shown this non-poisoning effect [JES, 149 (2002) A1400]. What do you think?
Glue is discharged from a syringe tip at a constant pressure P through a constant time period t.
The original tip is of diameter d1= 0.20 mm. A new tip is used of diameter d2 = 0.25 mm.
Considering only the tip of the syringe i.e. constant length and constant diameter, does the flow rate (be it mass flow rate or volumetric flow rate) decrease with the new tip for P and t ?
Could you help me?

Accuracy assessment of thematic map is often performed using groung truth sample points, generated randomly. There are techniques to evaluate the appropriate number of sample points. However, since those observation are "local", I have the strong feeling this strategy might fail to detect severe spatial inaccuracies (i.e, checking the accuracy of detected contours of different land cover patches obtained as a result of supervised classification).
As such, I was wondering how transect lines can help here. Since they provide a continuous information along a line over the mapped area, I was wondering how thematic accuracy can be assessed this way ? I came accross an interesting read (Skidmore, A. K., & Turner, B. J. (1992). Map accuracy assessment using line intersect sampling. Photogrammetric Engineering and Remote Sensing, 58, 1453-1453), however I missed some important details and could not be able to apply the method described in the paper correctly.
Any thoughts ?
