As mentioned in Section , a series is one of the possible realizations of a stochastic process.A process is a phenomenon (response variable), or a set of phenomena, which is organized along some independent axis. In most cases, the independent axis is time, but it may also be space, Cited by: 4.

Correlation between the cm solar flux (F ), the visible solar spot area (S d) and the geomagnetic planetary index (A p) have been investigated for the day intervals over the period F and S d are the indices connected with the solar UV-radiation.

A p is the index connected with the corpuscular radiation. S d does not correlate usually with A : A. Fominov. vide the Ap index, the planetary value. Similarly, the Kp index is the plan-etary average of all the K indices at ob-servatories around the globe. Values between 0 and 1 represent quiet magnetic conditions and this would indicate good HF band conditions, subject to a suffi-cient level of solar flux.

Values between. and HF propagation. A good discussion of solar indices is also provided in the September QST magazine. K7VVV reports that the solar flux mean for December 26 through January 1 was while the planetary A index mean was The average daily solar flux for the past six year is shown in the table below.

(vi) The geomagnetic indices (aa, Ap, and \(Kp\)) all have northern dominance during positive magnetic polarity epoch (–), while the asymmetries shifts. The solar cycle distribution of intense geomagnetic storms has been studied for cycles 20 and 21 (–), using values of the Dst index index > nT.

It is claimed that a dominant dual-peak (DP) distribution exists in the solar cycle variability of these storms, with one peak occurring at the late ascending Cited by:   A detailed knowledge of the solar resource is a critical point in the performance of an economic feasibility analysis of solar thermal electricity plants.

In particular, the Direct Normal solar Irradiance (DNI) is the most determining variable in its final energy yield. Inter-annual variations of DNI can be large and seriously compromise the viability of solar energy by: 3.

Aggregation and heterogeneity have long been recognized as thorny problems for empirical studies of the investment behavior. Nickell () identifies three major problems on aggregation and heterogeneity.

First, “the question arises as to whether one can construct aggregates for the outputs, the capital good inputs and the labour inputs so that it is possible. The apparent brightnesses of Titan and Neptune, near Å and Å, have changed by up to 10% and 3% respectively sinceand are highly correlated, with the variations at Titan apparently lagging those at Neptune by approximately six months.

Since these changes are larger than any plausible solar variation in visible light, the implied cause is an Cited by: 3.
