Therefore, the interpretation of experimental data can be very complicate.
In Fig. 2, the extremum of the heat capacities at the melting and freezing points, derived from the differentiation of the caloric data, are displayed. 3.1 Size dependence of the melting and freezing temperature The melting and freezing temperature (obtained from slow cooling processes) of silver nanoclusters with different size obtained from the extremum of the heat capacities are shown in Fig. 3.
Fig. 3 Atom number dependence of melting and freezing temperature of silver nanoclusters, the solid and dash lines are least square fit to the data.
As the increase (or decrease in cooling processes) of total energy cannot balance the reduction (or increase in cooling processes) of potential energy, the kinetic energy and potential energy are converted into each other, leading to a lower (or higher in heating processes) temperature.

The approach selected to achieve this aim has been to perform the full-scale neutron transport calculations with a Monte Carlo code employing modern continuous energy neutron data, in conjunction with a model set-up on the basis of 3D deterministic core simulations by SCIENCE [9] code which accounts for reactor operation conditions in a detailed manner.
The general data and dimensions of the Daya Bay-2 reactor are selected from the design manual.
Space truncation is one of the most efficient methods for variance reduction for a Monte Carlo application of the current type.

The pore diameter was calculated from the applied pressure assuming cylindrical pores, to give cumulative mercury intrusion volume versus pore diameter data for meso- pores and macropores.
In addition, a significant reduction in pore volumes (in a range of 10–30% from the initial values) was observed for the bulk samples.

The least square method is utilized by fitting the discrete data of objective function in Ref. [11], which can subject to the restriction of continuous variables.
But the results using this method will bring rounding error, which is caused by human participate in data processing.

In another experiment, we observed an extremely strong reduction of the resistance of a SOI layer by GBs [15].
A drain current of ID > 1x10-2 A induced by a single dislocation was estimated by data extrapolation from measurements of FETs containing varying dislocation number.
Indeed, for a delta-layer with 2 nm thickness and a donor concentration of 3 x 1018 cm-3 device simulation yields a transistor characteristics that describes the measured data for the nFET in a qualitative manner, see [16] for details.
Correspondingly, for the hole mobility in the pFET with GB in the channel we deduce from the experimental data µp ~ 10.000 cm2/Vs at 300 K.
