Markov Models of Steady Crystal Growth

GPU-Enabled Steady-State Solution of Large Markov Models

We describe a novel parallel steady-state solver that uses NVIDIA’s Compute Unified Device Architecture (CUDA) library to perform calculations on a graphics processing unit (GPU). We demonstrate speed-ups of over 8 times compared with a CPU-only solver. We also discuss a parallel implementation which runs on multiple GPUs on separate machines, and explain how we deal with allocating appropriate...

Asymmetric Effects of Government Spending on Economic Growth Over the Business Cycle: Application of Markov Switching Models

This paper is  investigated four subject with uses iranian economic data and using the Markov-Switching model during the period (1369: 3-1393: 4), So that: (a) were Examined impact of  the positive and negative Fiscal  shocks on Iran economic growth ( B) the Hypothesis  impact of negative shocks is greater than a positive shock was tested. (C) were tested the impact of government expenditure (f...

EFFECT OF SPIRAL DESIGN ON CRYSTAL ORIENTATION DURING SINGLE CRYSTAL GROWTH

Geometrical design of the spiral crystal selector can affect crystal orientation in the final single crystal structure. To achieve a better understanding of conditions associated with the onset of crystal orientation in a spiral crystal selector, temperature field was investigated using three-dimensional finite element method during the process. Different geometries of spiral crystal selec...

Investigation of Different Stages of Aluminum Fluoride Crystal Growth

Crystallization of Aluminum fluoride at atmospheric pressure has been considered. Structure, size and shape of crystals formed during the crystallization process have been investigated. By applying the direct analysis method for the existed aluminum in solution, the aluminum fluoride nucleation process has been detected as a concentration valley at the outset of crystallization process. The...
