Abstract: A system, processes, and a computer-readable storage medium are provided method includes receiving a search query including one or more of a textual phrase, a document, or data including metadata from a user. For example, a processor may execute a theme-generating machine learning algorithm to generate a theme of the search query. Profiles of other users are identified as similar to a profile of the user may be located. A search history of each of the located other users may be located in the collected search history. Content in the searchable content that corresponds to the generated theme of the search query and according to a result of the evaluation of the located search history of each of the other users may be obtained. The obtained content may be scored based on a scoring algorithm and output a set of scored search results to the input/output device.

Abstract: To obtain hydrogen from a gaseous C2minus feed, it is cooled from a first to a second temperature level at a first pressure level forming one or more condensates. A gaseous remainder is cooled to a third temperature level and subjected to a counterflow absorption at the first pressure level, obtaining a top gas rich in hydrogen and methane and a sump liquid. The former is heated and subjected to pressure swing adsorption at the first pressure level, forming a product stream rich in hydrogen and depleted in or free from methane. The condensate(s) and/or the sump liquid is/are expanded to and fed into a low pressure demethanizer at the second pressure level. The counterflow absorption is carried out using fluid taken from the demethanizer at the second pressure level, compressed in gaseous form to the first pressure level and cooled to the third temperature level.

Abstract: A method (100, 200) is proposed for obtaining hydrogen from a gaseous feed mixture rich in hydrogen, methane and hydrocarbons having two carbon atoms, wherein fluid of the feed mixture is cooled from a first temperature level to a second temperature level at a first pressure level such that one or more condensates are precipitated out of the fluid of the feed mixture, leaving a residual gas, fluid of the residual gas is further cooled to a third temperature level and subjected to a counterflow absorption at the first pressure level, thereby obtaining a top gas rich in hydrogen and methane and a sump liquid, fluid of the top gas is heated and subjected to pressure swing adsorption (9) at the first pressure level, to form a product stream which is rich in hydrogen and depleted in or free from methane, and fluid of the condensate or condensates and/or of the sump liquid is expanded from the first pressure level to a second pressure level and is fed into a low pressure demethanizer at the second pressure level.

Abstract: An ice building machine for spraying a fluid comprising water to form ice is described. The machine comprises: a chassis; a power generating source connected with the chassis; a control module electrically connected with the power generating source; and a fluid spray system coupled with the chassis and arranged to spray a fluid under control of the control module and powered by the power generating source, the fluid spray system arranged to access the fluid from below a lower surface of the ice building machine.
