In this paper we initiate the concept of fundamental domain in locally compact hypergroups and then we introduce the Borel section mapping. In fact, a fundamental domain is a subset of a hypergroup K including a unique element from each cosets, and the Borel section mapping is a function which corresponds to any coset, the related unique element in the fundamental domain. Finally, as an application we show that if K is a locally compact hypergroup and H is one of its commutative subhypergroup, then there exists an isometric transform Z from L^2 (K) to L^2 (H ̂,L^2 (H\K)). For this, we apply the dual of hypergroups and specially we use the Plancherel Theorem. This transform is a version of the Zak transform on locally compact hypergroups which can be considered as an extension of the usual notion of Zak transform in the case of locally compact groups.

The sample period of the study is from 1387 to 1397, when Tehran stock exchange index is approximately closed to Heston model. In this work, the considered pricing is done in two sections with different period of times. At first, The fast Fourier transform is applied for solving our main model. In the sequel the results of the considered pricing are shown that power option pricing can not follow the Heston model that means it causes the arbitrage situations in our considered market, Tehran stock exchange.

This research is based on methods such as, Fast Fourier analysis, curve waveform, the bearing rollers and phase angle in frequency space were analyzed, followed by imperfections and their possible origin have been nominated. After surveying data and survey results, the disadvantage caused by the unbalance of electric monetary and non-monetary alignment in transmission was measured.The vibration amplitude and phase angle errors associated with the use of changes and fixes have been identified.

22 - Simplification of Earthquake Accelerograms for quick time history Analyses by Using Their Modified Fourier Inverse Transforms

In such cases most codes recommend time history analysis, which is very time consuming, mainly since the time step size of the digitized accelerograms is usually very small. Therefore, if the time history analysis can be performed by large time steps without losing much precision, it would be very helpful. In the present study, a method is introduced for simplification of accelerograms based on the modification of their fourier analyses. For this purpose, at first the fourier spectrum of the accelerograms is calculated. Then, by using a computer program, created by the authors, a modified version of fourier spectrum is produced and then the corresponding inverse fourier transform is calculated using a relatively large time step, which is computed based on the all major earthquake frequencies (which is usually 5 to 10 times larger than the original accelerograms time step) in order to create the simplified accelerograms. It is obvious that time history analysis by using this simplified accelerograms will be much less time-consuming. Numerical results indicate that the maximum response values obtained by using the simplified accelerograms have approximately 5 to 10 percent error depending on the type of the structure and earthquake characteristics Manuscript profile -

In this study, FTNIR and FTMID were used to evaluate the amount of tetracycline in raw milk and compared with the reference HPLC method. Forty milk samples were prepared with different concentrations of tetracycline 0, 50, 100 and 150 ppb. Also, by comparing the control sample with the samples containing tetracycline, the most changes in the near-infrared spectrum occur in the wavelength range of 5200 to 5000 and 7000 to 6800 and the changes of the middle infrared spectrum occur in the wavelength range of 700 to 600, 1700 to 1500 and 3400 to 3200 cm-1. Using these predictions, the amount of tetracycline was predicted by NIR and MIR methods with correlation coefficients of 0.99 and 0.90 and RMSEP error rates of 18.60 and 20.06, respectively. Although the correlation coefficient of both methods is high, but the error rate of the prediction method is high for both methods, especially the MIR method. But the results of the NIR spectrum are closer to the reference method (HPLC) and can replace this method. Due to the lower error rate of NIR and the advantages of this identification method compared to High Performance Liquid Chromatography, this method can be introduced as a suitable alternative to destructive methods of measuring tetracycline in milk.

In this work, a comparative study on the effect of the natural rubber protein content that was obtained by two Kjeldahl and Fourier transform infrared spectroscopy methods considered on the tensile properties of rubber compounds and second order correlation models were obtained. These models were used to predict the tensile properties of natural rubber based compounds. The results showed that the Fourier transform infrared spectroscopy method is more successful for prediction of the properties. Tensile strength and modulus 100% were predicted by less than 10% error, elongation at break and modulus 300% were also estimated by less than 25% error. This new approach makes it possible to predict the tensile properties of rubber compounds before preparing,, by consuming a small amount of natural rubber and using a fast and non destructive technique.
