Just as the power of the open-source design paradigm has driven down the cost of software to the point that it is accessible to most people, the rise of open-source hardware is poised to drive down the cost of doing experimental science to expand access to everyone.To assist in this aim, this paper introduces a library of open-source 3-D-printable
Common ontology languages, construction principles and construction methods were summarized.It was considered that constructing coal mine safety ontology should adopt OWL-DL language and the construction method of cyclic acquisition method or seven-step method.Current research status of the coal mine Dog-Treats safety ontology was analyzed from asp
Crude oil is one of the most traded non-food products or commodities in the world.In Indonesia, crude oil will still be a contributor to Dog-Treats the gross domestic product in 2021.The excessive consumption of fuel oil (BBM) in Indonesia has resulted in a scarcity of crude oil, especially diesel.Forecasting the price of Brent crude oil is an impo
With the introduction of cold electron sources such as nanotubes, X-ray sources became small in size so that many sources are installed in array to form stationary CT, which brings benefits of simplicity in mechanism and fast response.However, the nanotube-based X-ray source is still singly packaged and hence density of X-ray sources is limited, wh
The question of how self-driving cars should behave in dilemma situations has recently attracted a lot of attention in science, media and society.A growing number of publications amass insight into the factors underlying the choices we make in such situations, often using forced-choice paradigms closely linked to the trolley dilemma.The methodology
