Compared to opencut mining, underground coal mining is more common in Australia due to its lesser impact on the environment. Although there are several underground mining methods, such as the longwall, pillar, bord, and miniwall, longwall mining is the most commonly used method due to its high efficiency. However, longwall mining does lead to significant ground subsidence. Mining subsidence is ...

Land leveling is one of the most important steps in soil preparation and cultivation. Although land leveling with machines requires considerable amount of energy, it delivers a suitable surface slope with minimal soil deterioration as well as damage to plants and other organisms in the soil. Notwithstanding, in recent years researchers have tried to reduce fossil fuel consumption and its delete...

A major issue of machinery fault diagnosis using vibration signals is that it is over-reliant on personnel knowledge and experience in interpreting the signal. Thus, machine learning has been adapted for machinery fault diagnosis. The quantity and quality of the input features, however, influence the fault classification performance. Feature selection plays a vital role in selecting the most re...

Recent work in Optimality Theory (Prince and Smolensky 1993, McCarthy and Prince 1993, to appear) has suggested that phonological regularities can be explained without reference to phonological rules, strictly in terms of constraints on representational wellformedness. A unique aspect of Optimality Theory (OT) is that candidates are evaluated in parallel: there is no serial derivation. Given th...

Ausgehend von Thomas Nagels Aufsatz " What is it like to be a bat? " und Alan Turings Aufsatz " Computing machinery and intelligence " wird argumentiert, das eine erfolgreiche Interaktion von Menschen und autonomen artifiziellen Agenten vor allem darauf beruht, welche Eigenschaften Menschen jenen Agenten zuschreiben und nicht so sehr, ob diese Agenten jene Eigenschaften wirklich besitzen. Diese...

Alan Turing begins his 1950 Mind article, “Computing Machinery and Intelligence,” with the following straightforward pronouncement: “I propose to consider the question ‘Can machines think?’ ” He quickly (too quickly?) argues for “replacing” the original question with another “which is closely related to it and is expressed in relatively unambiguous words.” (Please note the vagueness of the clai...

This paper outlines the iterative stages involved in designing and developing a blended course of English for General Academic Purposes (EGAP) at Osaka University. First, the basic Successive Approximation Model (SAM 1) is introduced as the guiding instructional design model upon which the course was created. Afterward, the stages of design and development of the blended course are explained wi...
