Calculation of Fetal Weight Estimation Displayed with TFT LCD

Fetal weight estimation during pregnancy is one of the beneficial ways to solve morbidity and death during labor problem. Manually, the fundal height is measured from the edge of the pubic symphysis to the top of the uterine fundus by following the arch of the uterus, using a measuring tape. The purpose of this study is to develop an easy way to count fetal weight estimation so midwives don't have to count manually. The calculation of fetal weight estimation tool uses a variable resistor (potentiometer) as a sensor to measure the fundal height. Then it will be processed in microcontroller. The measurement results are fundal height and estimation fetal weight that will be displayed on the TFT LCD. Based on the results of measuring the fundus uterine height as much as 6 times against the measuring tool (ruler), there is no error in the device so it can be concluded that this tool can be used according to its function. This calculation of fetal weight estimation tool is portable and easy to use to help midwives count the fetal weight estimation quickly

Calculation of epsilon'/epsilon

I shortly review the present status of the theoretical calculations of epsilon'/epsilon and the comparison with the present experimental results. I discuss the role of higher order chiral corrections and in general of non-factorizable contributions for the explanation of the Delta I = 1/2 selection rule and direct CP violation in kaon decays. Still lacking reliable lattice calculations, analytic methods and phenomenological approaches are helpful in understanding correlations among theoretical effects and the experimental data. Substantial progress from lattice QCD is expected in the coming years.Comment: 10 pages, Invited talk at the 9th Int.

On Calculation of Amplitudes in Quantum Electrodynamics

A new method of calculation of amplitudes of different processes in quantum electrodynamics is proposed. The method does not use the Feynman technique of trace of product of matrices calculation. The method strongly simplifies calculation of cross sections for different processes. The effectiveness of the method is shown on the cross-section calculation of Coulomb scattering, Compton scattering and electron-positron annihilation.Comment: 4 page

Arbitrary shape surface Fresnel diffraction

Fresnel diffraction calculation on an arbitrary shape surface is proposed. This method is capable of calculating Fresnel diffraction from a source surface with an arbitrary shape to a planar destination surface. Although such calculation can be readily calculated by the direct integral of a diffraction calculation, the calculation cost is proportional to $O(N^2)$ in one dimensional or $O(N^4)$ in two dimensional cases, where $N$ is the number of sampling points. However, the calculation cost of the proposed method is $O(N \log N)$ in one dimensional or $O(N^2 \log N)$ in two dimensional cases using non-uniform fast Fourier transform

Comment on ``New ansatz for metric operator calculation in pseudo-Hermitian field theory''

In a recent Brief Report by Shalaby a new first-order perturbative calculation of the metric operator for an $i\phi^3$ scalar field theory is given. It is claimed that the result is an improvement on a previous calculation by Bender, Brody and Jones because it is local. Unfortunately Shalaby's calculation is not valid because of sign errors.Comment: 2 pages, no figures. This comment replaces the previous comment on the Brief Report by Shalaby. In the previous comment we pointed out that Shalaby's calculation failed in all but 2 space-time dimensions. We have subsequently found additional errors which mean that the calculation is not valid even in that cas
