Abstract

In a few short paragraphs of The Problems of Philosophy Bertrand Russell presents his theory of introspective knowledge based on the concept of knowledge by acquaintance. In this article, I critically analyze these comments by Russell and their proposed application by contemporary authors, including Brie Gertler (2001; 2011) and Laurence BonJour (2003). I show how these theories differ from the competing ‘inner‑sense theories’ and try to show that they are inconsistent with Gareth Evans’s ‘transparency’ observation. Then I compare acquaintance theories with Alex Byrne’s (2005; 2012) ‘transparency’ theory and show that Byrne’s theory offers a simpler account of mechanisms governing introspection and attribution of mental states to other agents than the observer.

Abstract

Shaft is a machine element which is used to transmit rotary motion or torque. During transmission of motion, however, the machine shaft doesn't always rotate with a constant angular velocity. Because of unstable current or due to sudden acceleration and deceleration, the machine shaft will rotate at a variable angular velocity. It is this rotary motion that generates the moment of inertial force, causing the machine shaft to have torsional deformation. However, due to the elasticity of the material, the shaft produces torsional vibration. Therefore, the main objective of this paper is to determine the optimal parameters of dynamic vibration absorber to eliminate torsional vibration of the rotating shaft that varies with time. The new results in this paper are summarized as follows: Firstly, the author determines the optimal parameters by using the minimum quadratic torque method. Secondly, the maximization of equivalent viscous resistance method is used for determining the optimal parameters. Thirdly, the author gives the optimal parameters of dynamic vibration absorber based on the fixed-point method. In this paper, the optimum parameters are found in an explicit analytical solutions, helping the scientists to easily find the optimal parameters for eliminating torsional vibration of the rotating shaft.

Abstract

The article considers those fragments of panegyrics as to Russian saints that directly or indirectly go back to the Praise of Saints Euthymios the Great and Sabas the Sanctified by Cyril of Scythopolis (in Slavic manuscripts known as Cyril the Monk). There are two instances of a conscious appeal on the part of Russian hagiographers to the Praise, while these also employed the Life of Sabas the Sanctified by Cyril of Scythopolis in their writings along with mentioning the names of Euthymios and Sabas.
