Atomistic simulations are employed to investigate chemical short-range ordering in two body-centered cubic refractory multi-principal element alloys, HfMoNbTaTi and HfNbTaTiZr, its influence on their ideal simple shear strengths. Both the alias affine strengths analyzed {110} {112} planes opposing 111 directions. In both quinary local of NbNb, TaTa, HfNb, HfTa, NbTa is preferred as annealing te...

Abstract. The formal structure of geometrical thermodynamics is reviewed with particular emphasis on the geometry of equilibria submanifolds. On these submanifolds thermodynamic metrics are defined as the Hessian of thermodynamic potentials. Links between geometry and thermodynamics are explored for single and multiple component, closed and open systems. For single component, closed thermodynam...

hub covering problem (hlp) is a very popular areas of research for its wide ranges of applications in different service or manufacturing industries. this paper considers a bi-objective hub covering location problem with congestion. the objectives minimize the total transportation cost and the total waiting time for all hobs, respectively. the resulted multi-objective decision-making problem is ...

Abstract The balanced homodyne detection as a readout scheme of gravitational-wave detectors is carefully examined from the quantum field theoretical point view. in specifies directly measured operator detection. This specification necessary when we apply recently developed measurement theory to detections. We examine two models measurement. One model which at photodetector Glauber’s photon num...

in this paper we define the notions of ultra and involution ideals in bck-algebras. then we get the relation among them and other ideals as (positive) implicative, associative, commutative and prime ideals. specially, we show that in a bounded implicative bck-algebra, any involution ideal is a positive implicative ideal and in a bounded positive implicative lower bck-semilattice, the notions of...

INTRODUCTION Water/fat resolved MR imaging is gaining considerable interest in a number of clinical applications. Chemical shift encoding-based imaging approaches, like three-point Dixon [1] or IDEAL [2], provide high quality water/fat separation. Both approaches treat the spectral composition of water and fat as idealized single peak spectra with infinite signal lifetime. However, in reality, ...
