Optical Characterization of Atmospheric Aerosols via Airborne Spectral Imaging and Self-Organizing Map for Climate Change Diagnostics

John W. Makokha, Jared O. Odhiambo
Self-Organizing Map (SOM) analysis is used to perform optical characteri- zation of both Aerosol Optical Depth (AOD) and Angstrom Exponent (AE) retrieved from Moderate-resolution Imaging Spectroradiometer (MODIS) in relation to Precipitation Rate (PR) from Tropical Rainfall Measurement Mission (TRMM) over selected East African sites from 2000 to 2014 and further diagnose climate change over the region if any. SOM reveals a marked

The Effect of Spike and Gap Deconvolution on 2D Land Seismic Data

Hassan Z. Ali, Hassan A. Thabit
In this paper we are performing Spiking and Gap deconvolution on land 2D data; we are applying on the shot and stack data with operator length (200 ms), while in the gap deconvolution it is used different gap window (16.24 ms). The quality of output data is better than input data, and there is homogeneity in the distribution of frequencies. Also the band width of frequencies is increasing and smoothing spec

Strength Limit of Earth: A New Fundamental Phenomenal Factor for Universe’s Precise Scientific Perceptions and Descriptions

Mohammad Salehi Alashti
Intuition of many different unsolved problems and questions remains the “sorest troubles” in basis and applied sciences particular in physics today. Also presented physical models doesn’t describe world’s framework aright and these make lots of defects to understand sciences and solve scientific problems. Therewith no one can formulate the complicate relation(s) between all existences’ and sciences’ components. However,

Seismic Source Modeling in the Shores of Western Makran

Mahdi Modiri, Amir Barzegari, Amir Sahebalzamani, AbdolReza Hashemi
Makran is an active subduction zone with a lower activity rate in comparison with other similar subduction zones. In the extent of Makran seismotectonic province, from coastline up to 70 Km distance onshore, the earthquakes are shallow whilst further inland, focal depths of the earthquakes are deeper. Con-sidering the low seismic activity rate, lack of adequate and reliable seismic data and uncertainty about earthquake hazard cont

Statistical Analysis of Natural Water Conductivity Data Behavior in Two Wells: Seismic Coastal Border Limits of Guerrero-Oaxaca States, Mexico

Fidel Martínez-García
In this document, with the purpose of strengthening more in the knowledge of the previous events on the earthquakes, the possible connection between natural voltage and electromagnetic energy emanating from the inner layers of the Earth and the seismic activity in the Mexican seismic coastal border, is evaluated, through an indirect estimation of the statistical analysis of natural water conductivity data (μS/cm) and the seismic a

The Precursor of Tectonic Earthquake in Telluric Current

Igor Petrovich Dobrovolsky
The calculation of the precursor of the tectonic earthquake in the telluric current is carried out on the basis of the main equations of the telluric current and the theory of preparation of the tectonic earthquake. Results do not contradict data of field observations. Methodical significance of work is especially important.

Impulse Bursts of Geomagnetic Pulsations as the Ground Signature of Contact of Interplanetary Irregularity with the Dayside Magnetopause

V. A. Parkhomov, B. A. Dovbnya, N. L. Borodkova, A. V. Dmitriev, V. V. Safargaleyev, A. Y. Pashinin
The aim of the present article was to analyze features of interactions between an interplanetary shock wave and the magnetosphere on the basis of comparative analysis of geomagnetic variations observed during a sudden commencement (SC) by satellites and ground-based stations with high time resolution. A case study of the interaction of an interplanetary shock wave (ISW) with the magnetosphere was carried out on April 23, 2012. Statistical analysis was based on 11 SC events occurring from 1988 to...

Cumulative Perturbations Affecting a Spacecraft on a Mars Equatorial Orbit from the Waxing and Waning of the Polar Caps of the Planet

Jean-Pierre Barriot
We demonstrate in this paper that periodic variations of the J2 gravity coefficient of a planet induce small cumulative perturbations on a given family of circular equatorial orbits, and that these perturbations could be measurable with current radiosciences technology. For this purpose, we first consider a Poincaré expansion of the Newtonian equations of motion. Then, by using Floquet’s theory, we demonstrate that, unlike the excitation mechanism, the perturbations are non- pe...

The Estimation of the Error at Richardson’s Extrapolation and the Numerical Solution of Integral Equations of the Second Kind

Igor Petrovich Dobrovolsky
The mode of definition of the error at polynomial Richardson’s extrapolation is described. Along with the table of extrapolations the new magnitudes reflecting expediency and efficiency of extrapolation are entered. On concrete examples it is shown that application of Richardson’s extrapolation to a solution of integral equations has appeared rather effective and gives a solution with a high exactitude. Application of formulas of interpolation leads to a solution in the analytical aspect.
