We have obtained empirical relations between the p-mode frequency shift and the change in solar activity indices. The empirical relations are determined on the basis of frequencies obtained from BBSO and GONG stations during solar cycle 22. These relations are applied to estimate the change in mean frequency for the cycle 21 and 23. A remarkable agreement between the calculated and observed fre...

ω0 is the frequency of p-mode in the reference model, ω is the observed frequency for the same mode and w = ω/(l + 1/2). The function H1(w) which is related to the sound speed difference between the model and the Sun, provides another measure of the sound speed difference. Similarly, H2(ω) which reflects the differences in the surface layers is better suited to test different formulations of so...

Post-evaluation for agricultural project (PEAP) is an important indispensable aspect of agricultural project cycle management. Based on the comparison of the virtual situation and in advanced anticipation of the investigation, PEAP can be used to determine the variation and find the improving method through analyzing the reason, feedbacking the information, and summarizing the lessons, so as to...

Ecotourism is known as a type of sustainable tourism which helps both conservation and development, but many of tourism sites go to instability and self-destruction because of unsuitable environment assessment. Besides it is necessary to introduce new region for increasing of protected area in Iran. Using related criteria is an appropriate method for selection of suitable protected area and eco...

We have analysed the recently available GONG p-mode frequencies and splitting coefficients for a period of three and half years, including the rapidly rising phase of solar cycle 23. The analysis of mean frequency shift with different activity indices shows that the shift is equally correlated with both magnetic and radiative indices. During the onset of the new cycle 23, we notice that the cha...

The exponential sensitivity of cluster number counts to the properties of the dark energy implies a comparable sensitivity to not only the mean but also the actual distribution of an observable mass proxy given the true cluster mass. For example a 25% scatter in mass can provide a ∼ 50% change in the number counts at z ∼ 2 for the upcoming SPT survey. Uncertainty in the scatter of this amount w...
