Questions related to Engineering
Some married couples used their spouses as their next of kin while some used the first child, others used the first male child. Some people also preferred to use their siblings for next of kin. Who do you think should be the next of kin as a married person or unmarried person ? What are the criteria of choosing the next of kin? I will appreciate candid answers to this question.
How is performance of Artificial Neural Network (ANN) as compare to other machine learning or artificial intelligence technique? How is ANN's performance measures? Particularly, in the field of engineering applications.
Do we need to be specific?
Sometime I feel that if we become specific with more details when we ask the questions, we loose some potential researchers from other fields. So the number of answers reduce, then it is difficult to get attention of other researchers. So at the end we do not get many answers.
What is your experience and opinion on this? Please share your thoughts as well.
I am going to check the effectiveness of tuned liquid damper as seismic control and i want to take sample multi story building with out designing the structural elements. so to take that sample what from which perception to put first cross-section of structural elements with out helping of architectural engineer?

I wish to know more points, apart from the above plz suggest.
Scientists always involve in research and even they are pioneered,but didn't lead nations ,not in all world ,not in America,but in China,
ina has even more scientists in key positions in the government. President Hu Jintao was trained as a hydraulic engineer and Premier Wen Jiabao as a geomechanical engineer. In fact, eight out of the nine top government officials in China have scientific backgrounds. There is a scattering of scientist-politicians in high government positions in other countries as well. German Chancellor Angela Merkel has a doctorate in physical chemistry, and, going back a bit, Margaret Thatcher earned a degree in chemistry.
One needn’t endorse the politics of these people or countries to feel that given the complexities of an ever more technologically sophisticated world, the United States could benefit from the participation and example of more scientists in government. This is obviously no panacea — Herbert Hoover was an engineer, after all — but more people with scientific backgrounds would be a welcome counterweight to the vast majority of legislators and other officials in this country who are lawyers.
Among the 435 members of the House, for example, there are one physicist, one chemist, one microbiologist, six engineers and nearly two dozen representatives with medical training. The case of doctors and the body politic is telling. Everyone knows roughly what doctors do, and so those with medical backgrounds escape the anti-intellectual charge of irrelevance often thrown at those in the hard sciences. Witness Senator Bill Frist, Gov. Howard Dean and even Ron Paul.
This showing is sparse even with the inclusion of the doctors, but it shouldn’t be too surprising. For complex historical reasons, Americans have long privately dismissed scientists and mathematicians as impractical and elitist, even while publicly paying lip service to them.
One reason is that an abstract, scientific approach to problems and issues often leads to conclusions that are at odds with religious and cultural beliefs and scientists are sometimes tone-deaf to the social environment in which they state their conclusions. A more politically sensitive approach to problems and issues, on the other hand, often leads to positions that simply don’t jibe with the facts, no matter how delicately phrased. Examples as diverse as stem cell research and the economic stimulus abound.
Politicians, whose job is in many ways more difficult than that of scientists, naturally try to sway their disparate constituencies, but the prevailing celebrity-infatuated, money-driven culture and their personal ambitions often lead them to employ rhetorical tricks rather than logical arguments. Both Republicans and Democrats massage statistics, use numbers to provide decoration rather than information, dismiss, or at least distort, the opinions of experts, torture the law of the excluded middle (i.e., flip-flop), equivocate, derogate and obfuscate.
Dinosaurs cavorting with humans, climate scientists cooking up the global warming “hoax,” the health establishment using vaccines to bring about socialism – it’s hard to imagine mainstream leaders in other advanced economies not laughing at such claims.
Often too interested in politics as entertainment, the media is complicit in keeping such “controversies” running. Doing so isn’t hard since vivid, just-so stories and anecdotes usually trump (or should that be Trump) dry, sometimes counterintuitive facts and statistics.
Skepticism enjoins scientists — in fact all of us — to suspend belief until strong evidence is forthcoming, but this tentativeness is no match for the certainty of ideologues and seems to suggest to many the absurd idea that all opinions are equally valid. The chimera of the fiercely independent everyman reigns. What else explains the seemingly equal weight accorded to the statements of entertainers and biological researchers on childhood vaccines? Or to pronouncements of industry lobbyists and climate scientists? Or to economic prescriptions like 9-9-9 and those of Nobel-prize winning economists?
Americans’ grandiose (to use Newt Gingrich’s malapropism) egalitarianism also helps explain why the eight or nine original Republican presidential candidates suffered little for espousing, or at least not clearly opposing, scientifically untenable positions. Jon Huntsman, the only exception, received excessive kudos for what seems a rather lukewarm acceptance of climate change.
To avoid receiving the candidates’ canned responses on these and other issues, I sometimes wish that a debate moderator would forgo a standard question about immigration or jobs and instead ask the candidates to solve a simple puzzle, make an elementary estimate, perform a basic calculation.
Of course, the other side of the “two cultures” chasm should bear some of the onus for this lack of communication between politicians and scientists. Too few scientists are willing to engage in public debates, to explain the relevance of their fields clearly and without jargon, and, in the process, to risk some jeering from a few colleagues. Nevertheless, American scientists do more on this front than those in most other countries.
Perhaps because the words rhyme, it’s sometimes said that attitude is more important than aptitude in helping to bring about innovation, economic progress and social change. The dubious corollary is that freewheeling Americans who question authority and think outside the box have an abundance of attitude that helps make up for a declining performance in science and technology.
Maybe so, but attitude can only go so far. There is certainly no requirement for a Singaporean science background, but scientifically literate government leaders who push for evidence-based policies and demonstrate a scientific outlook are needed more than glib panderers with attitude.s o why not let scientists lead pollitics?
I am wondering how an electron can gain and lose mass. What is the electron actually gaining and losing that causes its mass to change?
Specifically, my application is in an electron beam travelling from a cathode to an anode.
I am not a physicist or electrical engineer, so I am lacking some basic background knowledge. It's hard for me to understand how an electron, which is a fundamental particle that cannot be broken into anything smaller, can gain or lose mass.
I would very much appreciate any rudimentary explanations!

Is this affect the Earth Rotation And Revolution ?
The availability of technical equipment simplifies our live, and thus, also teaching. However, I have the impression that it seduces to show to much information and, moreover, since most of presentations are online available, students to not make any notes anymore since they can download everything. Thus, they follow like the presentation like a movie... and possibly do not understand the content. If you try to copy a graph from the blackboard or write an equation (inclusive errors which will be made and corrected during writing even from the presenter) requires some kind of active interaction.
Does our current teaching really improves the level of knowledge of our students?

I want to minimize the value of one variable which depends directly on four variables and indirectly on three variables.
I need to adjust the parameters from a machine (establised manually) to reduce the efect in "response" variable. Also, I have other variables which I can't choose their values.
I have at least 5000 observations which given some independent variables and the machine parameters established I have the response variable value.
I think in linear programming but I don't have an objective function and constraints but I want to minimize efects. Also I think in DOA and Taguchi but I dont have to do and experiment, I have 5000 experimients really done.
I will appreciate your responses! Thanks

In my opinion, the role of activating innovativeness and implementing new technologies in the industry is important for the effective economic development of the country and supports the sustainable development of the national economy.
In sustainable socio-economic development of the national economy, one of the most important issues is the activation of innovation and entrepreneurship in order to stimulate the development of business entities, especially those companies that based their business model on the implementation of new technologies, innovations, patents, including technical and engineering technology solutions, production, logistics, IT, process, management, etc. Therefore, the role of engineers is very large in such organized development of the national economy oriented in economic policy on socio-economic development with particular emphasis on the activation of innovation and supporting the development of companies that their business model rely on new technologies, including engineering technologies.
I invite you to the discussion
I am currently designing a deformable wheel for a six-wheeled lunar vehicle and I am trying to model the trafficability of this wheel on a lunar surface. To do this I am using Bekker’s Equations.
My question: I found normalized DP (drawbar pull) values of 26 for a wheel with grousers and a value of 0.48 for the same wheel, but without grousers. The value of 26 seems very high based on results I have found in other papers online so I am skeptical of my results and need help confirming that the assumptions and calculations I made make sense. I have attached a .pdf that walks you through what I did and assumptions I made. Along with this I highlighted areas where I am uncertain as they may be possible areas of error.
Thanks again for your time and any advice relating to this will be very helpful since this is my first time working with Bekker's equations and wheel-soil interactions in general.
Note: the soil characteristics I used were the recommend ones found in the Lunar hand guide
I believe the most fundamental discoveries of all times - nanomaterial.
Is my perception matches your opinion? What alternative you can suggest?why?
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!
Dear Respected Research Gate Members,
Nowadays, every company is interested to manage the appropriate level of inventory with demand. The inventory carrying costs are increasing on the one and not having inventory at the time of demand is a great loss. Now, everyone knows the impact of inventories on the profitability of the company. So, there are many practices to balance between the demand and the level of inventories. Few companing are even working with "zero inventory" concept. Please, share your expert suggestions on the following question.
Which manufacturing/management practices are more useful in managing inventories effectively & efficiently?
Thanks & Regards
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?

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!
