Note that contracts inherit all members of address, so it is possible to query the balance of the current contract using ethereum. Emacs Solidity Plugin for the Emacs editor providing syntax highlighting and giromill error reporting. Domain-specific programming languages Statically typed programming languages Ethereum. The compiler will for now not automatically discover source files for ethereum, so you solidity to provide it with all source files your project consists giromill. Modifiers can be used to easily change solidity behaviour of functions, for example to automatically solidity a condition prior to executing the function. Ethereum is a network that runs ethereum a big, single, public blockchain, where giromill can pay to access and store data in there.
Join over , Members. There are companies that specialise in being the trusted oracle, and designing systems to disintermediate themselves from having to be trusted with the datafeed. The mapping or the dynamic array itself occupies an unfilled slot in storage at some position p according to the above rule or by recursively applying this rule for mappings to mappings or arrays of arrays. Wind turbines Navier Stokes equations Control systems Researchers. In particular, the aim is not to force smart contract developers in having to trust Oraclize with the data they need. We are ready to actually do some initial testing and interact with our smart-contract.
Solidity, the hard-fork situation shows ethereum this really is a public chain, and if something really contentious happens on it, it could fork and your data could theoretically be subject to rollback, or the underlying asset class could drop in price steeply. The roughness of the surface can increase turbulence close to giromill ship and ethereum act to damp out very high frequency waves, especially immediately behind the hull. Your ideas might solidity acceptable to a journal refereed by other ethereum deists who don't question the existence of invisible giromill gods, but why should other people accept them as a basis for bioethics? Retrieved 11 May In solidity, functions can also be specified giromill external.
As long as they don't use their delusions to impose restrictions on others, it doesn't matter what nonsense they believe in. An appeal to authority? They don't have proof that here is such a higher mind, but they impose it on others as if they do. Question - What is the best method of finding optimal parameter combination for GA? After you have tuned the parameters, re-run the GA using another random number generator.
Have you just tuned the original algorithm to the original RNG? I'm glad people like Dawkins continue to fight against religious interference. It's not a futile fight. Aristotle's "scientific" ideas, promoted by the Catholic church, held back science for nearly years.
Catholics, and many other religious fundamentalists are still poking their noses into scientific matters, the bedrooms of consenting adults, and have the gall to pardon the pun pontificate on the reproductive rights of women. Question - How can I determine how the wind turbine will turn and give load? I used simpler flow models in my work.
Question - Has anyone objections about VertEolo project? It is a very important parameter in VAWT research. Question - Ex-Machina, God and bioethics: What should be the main bioethical issues to address to understand the unstoppable and unavoidable rise of AI?
They might also be viewed as someone who reduced the food available to a large number of people as some GMO opponents are in some regions , or they might be viewed as ridiculous, like the Luddites during. You need to include the blade lift and drag into a larger flow model, one that accounts.
You have a variety of models to choose from, from simple momentum models, like the double multiple streamtube model, to sophisticated CFD models. Be aware that the VAWT might not be able to accelerate through a tipspeed ratio of about 1. All you have given us is some silly musings from that jejeune jesuit de Chardin based on an imaginary being and the equivalent of a spirit world.
By all means, believe what you like, but don't expect scientists and researchers to be guided on what is ethical and necessary by that twaddle. Not just evidence of it, but also how you come to know it so intimately that we should consider it seriously. That is a very weak attempt at shifting the onus of proof. That onus is on you as the proposer. Your ideas might be acceptable to a journal refereed by other western-style deists who don't question the existence of invisible sky gods, but why should other people accept them as a basis for bioethics?
The book is a bit of a mess and needs better organisation. I found it difficult to work out the solidity of the turbines, and many other important things like how you will guarantee self-starting. It would help enormously if you had a nomenclature with a list of symbols at the start. That would allow easier comparisons with existing turbines and theory. You also need to update your financial and other estimates to account for the increasing numbers of domestic and other rooftop solar installations.
For example, rooftop solar now produces a substantial proportion of the power in Western Australia, and is increasing very rapidly in the USA and other places. Sorry, but you have solved nothing. You have a proposal as does Kirke in his ring-drive paper , that is all. There is a huge gap between proposing. Are you seriously claiming to have inside knowledge of the attitude of a putative creator to humans?
And, furthermore, that this knowledge should be a basis for the ethical treatment of animals? Have you thought about something a little more grounded in reality, i. What is the old technology used for building it?
Wiki has a page that you should start with. There are several references listed at the end of the page. You do not know where the plants will be located, so you don't know whether the turbines will be operating at that very optimistic efficiency for 24 hours every day. It is not rational to ignore the fact that there may be better renewable or non-renewable energy sources than wind in some locations.
You also need to adjust some figures and estimates to reflect the current price of oil. Yes, they should get out of the way. Especially if they are pushing a religious agenda. I tracked down the quote. Ng was referring to the 3 million truck drivers in the USA who will face competition from developments in driverless vehicles.
But I wanted to know some simple answers without having to wade through an entire book. It sounds like this is just a marketting ploy for your book. Sorry for the confusion, Ramon. My answer was to the question: My apparent negativity stems from my opinion that AI is rarely defined by people discussing the field, whether it is practitioners and researchers themselves, or fear-mongers and doom-sayers. I also thought that the movie was shallow, cliched crap, and as clumsy and weak as the old Frankenstein movies with their theme of "creation destroys creator".
Maybe it is thought-provoking and topical for many of the general public who are generally ignorant of actual science, and are very prone to be influenced by phrases such as "killer AI",. As a lead AI researcher at Google said, "You shouldn't be worried about killer robots, but what to do with the 2 million truck drivers who might be unemployed in the near future". I don't have the actual quote in front of me atm. Good luck with your…. It is complete nonsense to suggest that wind turbines alone can supply the energy needs for the entire world.
How would these turbines supply high density energy and power required for the transportation of enormous quantities of materials around the planet, e. How would these turbines supply the needs of populations that are not in favourable wind regimes? Firstly, AI in some form or another was "unleashed" a long time ago. Secondly, and much more importantly, you need to define much more clearly what you mean by the "AI" that you want to consider.
Question - Any input on modelling a ship's pressure signatures? The main ship parameters affecting wave propagation are the length, beam, draft, displacement and shape of the hull. There are some secondary parameters too, like the smoothness of the surface: The roughness of the surface can increase turbulence close to the ship and might act to damp out very high frequency waves, especially immediately behind the hull.
I think you would get some excellent insights into the problem by looking at how wave resistance of model hulls is estimated from towing tank measurements. There are a number of methods e. About 20 years ago, I released a free version of the program "Michlet" which was a thin-ship, linear code that allowed the user to input a wave field behind the ship.
The program used primarily memetic algorithms to search for the hull that produced…. Should some publications be excluded from consideration in determining "related researchers"? Researchgate gives a list of "related researchers" who are deemed to have "similar interests" because they have cited the same publication.

Department of Energy, wind energy could provide 20 percent of electricity in the U. A VAWT is a wind turbine design where the generator is vertically oriented in the tower, rather than sitting horizontally on top. While there are many VAWT designs, the one used in this study is called the straight-blade Darrieus type or H-rotor turbine. According to the researchers, small VAWTs possess the ability to effectively operate in the presence of high turbulent flow, which makes them ideal energy harvesting devices in urban and suburban environments.
To establish their results, the team input actual, time-resolved wind speed data into a numerical simulation that determined the total amount of energy captured by a turbine over a year of operation. Their wind data was accrued over the year from 3-D sonic anemometers mounted on the top of traffic posts, about 9 meters, or 30 feet, above ground, and positioned at nine different urban and suburban sites around Oklahoma City, Oklahoma. The researchers simulated 13 different wind turbine configurations, with a focus on four particular design parameters: The main performance measure used to identify the optimum design configuration was the percent of energy captured by the turbine over the course of the year relative to the available energy in the turbulent wind during the same time period.
Of the 13 design configurations, the optimal turbine design had the lowest moment of inertia. Interestingly, however, the researchers confirmed that even with the moment of inertia eliminated as a design parameter, this configuration was still the most ideal.
They also analyzed the various turbine designs for the levelized cost of energy LCOE at one of the test sites and found the values for blade characteristics necessary for economically viable options. The optimal design configuration at this site produced electricity at a cost 10 percent lower than the average national electricity unit price.
