The strapdown inertial navigation system (SINS) can be installed on a shearer and used for monitoring its position.However, under the complex environment of the mechanized mining face, the strong vibration of the shearer may cause large calculation error.First, the dynamic model of a double-drum shearer is built with a force analysis, and the spect
Increasing automotive powertrain electrification is impacting drivetrain complexity and the profiles of the fluids needed.Since the millennium, drivetrain fluid viscosities have been reduced QUICK B12 for better efficiency, but this new challenge is driving them to unprecedented low levels.This paper assesses some of the potential implications of u
In January 2006, students from CUSSW and Union Theological Seminary participated in an immersion course entitled, Katrina: Phone Socket Poverty, Race, and Social Work Practice.The aim of the course was to explore experientially the inequality exposed by Hurricane Katrina and its effect on some of the poorest communities and individuals in the Unite
The paper considers the class of Hamiltonian systems with two degrees of freedom.Based on the classical normal form, according to the rules of Born-Jordan and Weyl-MacCoy, its quantum analogs are constructed for which the eigenvalue problem is solved and approximate formulas for the energy spectrum are found.For particular values of the parameters
In this paper we compare two probabilistic data structures for association queries derived from the well-known Bloom filter: the shifting Bloom filter (ShBF), and the spatial Bloom filter (SBF).With respect to the original data structure, both variants add the ability to store multiple subsets in the same filter, using different strategies.We analy
