A principle of using high-resolution digital voltmeters (DVs) HewlettPackard 3458A for the measurement of AC voltages in DCV range is described. The method of approximate synchronous sampling is used, having only one sample per cycle of a working frequency close to 16 Hz, when the mean value of one-third cycle is measured. The beginning of integration is shifted for the same interval for every ...

One common objective of molecular simulations in chemistry and biology is to calculate the free energy difference between different states of the system of interest. Examples of problems that have such an objective are calculations of receptor-ligand or proteindrug interactions, associations of molecules in response to hydrophobic, and electrostatic interactions or partition of molecules betwee...

To clarify the phase diagram of QCD and thus the nature of matter under extreme conditions is one of the most interesting and fundamental tasks of high energy physics. Lattice QCD has been shown to provide important and reliable information from first principals on QCD at zero density. However, Lattice QCD at finite densities has been harmed by the complex action problem ever since its inceptio...

Shadow Hybrid Monte Carlo (SHMC) is a new method for sampling the phase space of large molecules, particularly biological molecules. It improves sampling of Hybrid Monte Carlo (HMC) by allowing larger time steps and system sizes in the molecular dynamics (MD) step. The acceptance rate of HMC decreases exponentially with increasing system size N or time step δt. This is due to discretization err...

Large sample properties of statistical inferences in the context of finite populations are harder to determine than in the iid case due to their dependence jointly on the characteristics of the finite population and the sampling design employed. There have been many discussions on special inference procedures under special sampling designs in the literature. General and comprehensive results ar...

We recently presented a new asynchronous demodulation method for phase-sampling interferometry. The method is based in the principal component analysis (PCA) technique. In the former work, the PCA method was derived heuristically. In this work, we present an in-depth analysis of the PCA demodulation method.

Collection of appropriate qualitative and quantitative data is necessary for proper management and planning. Used the suitable inventory methods is necessary and accuracy of sampling methods dependent the inventory net and number of sample point. Nearest neighbor sampling method is a one of distance methods and calculated by three equations (Byth and Riple, 1980; Cotam and Curtis, 1956 and Cota...
