Abstract The movement of the floating connecting mechanism between a hydraulic support and scraper conveyor is space movement; thus, when pushes conveyor, there an error actual distance theoretical moving distance. As result, cannot obtain straightness requirement. Therefore, law analyzed programmed into Unity3D to realize accurate pushing via support. Coal Seam + Equipment Joint Virtual Straig...

The dynamics of the subtropical pelagic ecosystems Northeast Atlantic are still poorly known due to high costs associated with sampling large oceanic areas. Top predators can be used as alternative low-cost samplers and indicators temporal variability such systems. To study variation in composition species through time broad Canary current region, we analysed foraging trips regurgitations Cory'...

Scrapers are advantageous earthmoving construction equipments as they are independently capable of excavating, hauling, and placing soil. Determining the suitable and the most economical selection of the size, model, and number of scrapers and pushers is a complex process that depends on multiple factors such as the haul-road conditions, equipment performance, operation’s travel time, etc. Equi...

Web scraping is the process of automatically extracting multiple WebPages from World Wide Web. It a field with active developments that shares common goal text processing, semantic web vision, understanding, machine learning, artificial intelligence and human- computer interactions. Current solutions range requiring human effort, ad-hoc, to fully automated systems are able extract required unst...

Production of aluminum alloy clad strips requires many processes, and a reduction in the number processes has long been demanded. A method to cast directly from molten metal using twin roll caster with copper rolls is proposed this work. Two types casters were designed tested. One was vertical-type tandem other equipped scraper. The casting conducted an oxidizing atmosphere. at speeds higher th...

The rotary vacuum filter is very basic in design, application and operation. It is also an extremely effective solid/liquid separation device due to its unique methods of handling (discharging) formed cake solids, relatively low operating labor requirements and its ability to filter continuous or batch process flows. The rudiments of a rotary vacuum filter installation include (Figure 1): (1) t...

Abstract This paper relates to a study on the formation of elongated preforms in CNC skew rolling mill. First, numerical analysis was performed investigate forming processes for three different parts: scraper, connecting rod, and hook. The shapes dimensions were designed, closed-died forging producing these parts simulated numerically. Distributions temperature, effective strain damage function...

Unlike MOOC platforms such as Coursera or edX, which typically partner with institutions of higher education, online knowledge marketplaces allow anyone to broadcast courses and charge for them. In this article, we investigate, through a mixed-method approach, the motivations strategies instructors Udemy Skillshare. Semi-structured interviews quantitative analysis characteristics Skillshare’s c...
