According to popular beliefs, the metamorphosis from man to werewolf reveals itself both psychically and physically: werevolves have eyes made of glass, nails like shovels, sharp and long fangs; bushy and long haired body; they are generally considered v...
Shovels, Trowels, and Ice Cream Scoops: in Search of the Right Tool to Explain Scientific Management
Article: Each term, when covering the history of management, many students have difficulty identifying with “ancient” management figures such as Frederick Taylor and Frank and Lillian Gilbreth. Even in Birmingham, Alabama, the former “Pittsburgh of the South,” Taylor‟s pig iron studies have little relevance. The bricklaying, sewing, and surgery studies by the Gilbreths fare only slightly better...
This paper discusses the design and deployment of low-cost Internet Things (IoT) in medium-scale open pit mines to optimise performance their mining small-scale trucks surface shovels. Low-cost IoT can be implemented operations automate collection process management information that is currently measured manually, replicating part results delivered by commercial Fleet Management Systems (FMSs) ...
Abstract Despite the progress made in last decades field of machine condition monitoring, there are still cases where current state art is not enough and new technologies advanced analysis methods required to prevent unexpected failures. One example planetary gearboxes (PGs), which one main components mechanical transmission systems heavy-duty machines such as off-highway trucks, electric rope ...
Aiming at the common problems of high working resistance, low soil disturbance, and rates missed extraction in operation carrot combine harvesters, a high-efficiency drag-reducing bionic soil-loosening shovel was designed this study. The physical parameters carrots were measured, using badger claw toe as prototype. wing structures designed. Based on EDEM discrete element simulation technology, ...
Most engineering artifacts behave in a continuous fashion, and this property is generally believed to underlie their dependability. In contrast, software systems do not have continuous behavior, which is taken to be an underlying cause of their undependability. The theory of software reliability has been questioned because technically the sampling on which it is based applies only to continuous...
Subsoiling has been acknowledged worldwide to break compacted hardpan, improve soil permeability and water storage capacity, promote topsoil deepening root growth. However, there exist certain factors which limit the wide in-field application of subsoiling machines. Of these factors, main two are poor quality high energy consumption, especially undesired tillage depth obtained in field with cov...
