This paper examines the questions of why and how foreign assistance was utilized successfully in South Korea but less so in Ghana, with a focus on the role of aid in the process of state building and state transition in these two countries. Before the 1960s, South Korea and Ghana shared approximately similar levels of GDP per capita. However, while South Korea achieved rapid economic developmen...

We study the adiabatic quantum dynamics of an anisotropic spin-1 XY chain across a quantum phase transition of the Berezinskii-Kosterlitz-Thouless type. The system is driven out of equilibrium by performing a quench on the uniaxial single-spin anisotropy, that is supposed to vary linearly in time. We show that, for sufficiently large system sizes, the excess energy after the quench admits a non...

A practical method for finding free energy barriers for transitions in high-dimensional classical and quantum systems is presented and used to calculate the dissociative sticking probability of H 2 on a metal surface within transition state theory. The reversible work involved in shifting the system confined to a hyperplane from the reactant region towards products is evaluated directly. Quantu...

The abstraction and addition reactions of H with trans-N(2)H(2) are studied by high-level ab initio methods and density functional theory. Rate constants were calculated for these two reactions by multistructural variational transition state theory with multidimensional tunneling and including torsional anharmonicity by the multistructural torsion method. Rate constants of the abstraction react...

I review the formalism of classical extensions of quantum mechanics introduced by Beltrametti and Bugajski, and compare it to the classical representations discussed e.g. by Busch, Hellwig and Stulpe and recently used by Fuchs in his discussion of quantum mechanics in terms of standard quantummeasurements. I treat the problem of finding Bayesian analogues of the state transition associated with...

the sorption isotherm and state diagram of sundried, golden and sultana raisins were constructed for investigation and comparison of the product stability. the isotherms were measured at 15, 25 and 35 °c using an isopiestic method and the data were modeled with gab model. glass transition temperatures of the products were measured by differential scanning calorimetery (dsc) and fitted to gordon...

multi agent markov decision processes (mmdps), as the generalization of markov decision processes to the multi agent case, have long been used for modeling multi agent system and are used as a suitable framework for multi agent reinforcement learning. in this paper, a generalized learning automata based algorithm for finding optimal policies in mmdp is proposed. in the proposed algorithm, mmdp ...

a wind farm is a collection of wind turbines built in an area to provide electricity. wind power is a renewable energy resource and an alternative to non-renewable fossil fuels. in this paper impact of wind farms in power system reliability is investigate and a new procedure for reliability assessment of wind farms in hl1 level is proposed. in proposed procedure, application of fuzzy – markov f...
