A signal mass piezoelectric six-degrees-of-freedom (six-DOF) accelerometer is put forward in response to the need for health monitoring of the dynamic vibration characteristics of high grade digitally controlled machine tools. The operating principle of the piezoelectric six-degrees-of-freedom accelerometer is analyzed, and its structure model is constructed. The numerical simulation model (fin...

abstract the traditional or liberal theory of contract always had encounter serious critics. the authors of this article have criticized this theory- based on new theory of unger (a pioneer in the critical legal studies movement) - and also have analyzed the strengths and weaknesses of that. this theory consists of a principle and a counter principle that include freedom of contract against the...

one of the most important macro-economic objectives of the countries is to create the necessary conditions for promoting economic growth. among them, we can point to political stability and economic freedom. political instability leads to wasting physical and human resources and social capital, which will be considered as an economic rollback. also, the rate of economic growth is associated wit...

This paper begins with a review and discussion of Gen and freedom of analysis as presented in the OT foundational works (Prince and Smolensky 1993; McCarthy and Prince 1993). The connection between freedom of analysis and our conception of the richness of the base is also considered. The core of the paper is a discussion of metrical phonology, exploring some specifics of the foot inventory whic...

We measure the effective mass (m) of interacting two-dimensional electrons confined to an AlAs quantum well while we change the conduction-band valley occupation and the spin polarization via the application of strain and magnetic field, respectively. Compared to its band value, m is enhanced unless the electrons are fully valley- and spin-polarized. Incidentally, in the fully spin- and valley-...

I started school in a one-room school house with nine grades but just six students. I was the entire kindergarten (called ‘primary’ in Iowa). The teacher would call us one by one to sit in the chair next to her desk. In my case, it was always a pleasant interlude. There was never a sense in my mind that she wanted me to do something. She would often mention something interesting and let it go a...

Compatibilist doxastic freedom Compatibilism entails that our actions and our doxastic attitudes are mostly free. My argument in defense of this claim will be that the compatibility of freedom and causal determination is not obvious; it needs explanation. Various explanations can be offered. If we apply these explanations to our doxastic attitudes, we are going to see that there is little reaso...

Strongly coupled semi-direct gauge mediation models of supersymmetry breaking through massive mediators with standard model charges are investigated by means of composite degrees of freedom. Sizable mediation is realized to generate the standard model gaugino masses for a small mediator mass without breaking the standard model symmetries. SLAC-PUB-1459 Work supported in part by US Department of...

In this paper we propose the realization of a bosonic-fermionic interaction in the context of trapped ions whose effect upon the ion center of mass degrees of freedom is properly speaking a spatial inversion. The physical system and its features are accurately described and some applications are briefly discussed.

Abstract This paper proposes an approach for the determination of analytical boundaries continuous, stick-slip and no motion regimes steady-state response a multi-degree-of-freedom (MDOF) system with single Coulomb contact to harmonic excitation. While these have been previously investigated single-degree-of-freedom (SDOF) systems, they are mostly unexplored MDOF systems. Closed-form expression...
