Improvements in Steam Shovels

Methods for Assessing Dynamic Performance of Shovels

Equipment specifications tend to quote highest achievable performance; but this specification does not tell the whole story of machine behaviour. In the case of shovels, many criteria are used for selecting new equipment, generally related to capital and operating cost, capacity, digging forces, reach, loading rate, and propel rate. Some are competing objectives, such as high loading capacity a...

Improvements on Single-shot STEAM with Optimised Signal Shaping for Diffusion Weighted Imaging at High Fields

Introduction: It was recently shown that a diffusion weighted Single-shot Stimulated Echo Acquisition Mode (DW ss-STEAM) pulse sequence is an alternative to the standard DW EPI at high fields [1-3]. By designing variable flip angles (vFA) for centric k-space acquisition without RF spoiling, more signal is utilised than usual. The iterative vFA-algorithm is based on the Extended Phase Graph form...

Some improvements in fuzzy turing machines

In this paper, we improve some previous definitions of fuzzy-type Turing machines to obtain degrees of accepting and rejecting in a computational manner. We apply a BFS-based search method and some level’s upper bounds to propose a computational process in calculating degrees of accepting and rejecting. Next, we introduce the class of Extended Fuzzy Turing Machines equipped with indeterminacy s...
