Candidates for the Slichter Triplet II

Authors: Herbert Weidner
Comments: 10 Pages.

The systematic search for coincident signals with a software-defined receiver in the data sets of fifteen superconducting gravimeters yields six striking signals in the frequency range 35 µHz to 100 µHz that can not be assigned to a known geophysical causes. Some might belong to the long-sought Slichter triplet.

Gravity Waves and Mercury Revise Geodynamo

Authors: Rodney Bartlett
Comments: 8 Pages.

Most people have a rough idea of the cause of Earth's magnetic field, don't they? It's the geodynamo, also called the magnetic dynamo theory. The heat from the solid inner core puts the liquid outer core in motion, and the movements of the outer core's electrically conducting fluids (such as molten iron) generate the planet's magnetic field. Electrically conducting fluids occur in the Sun, other stars and most planets – and are the scientifically accepted mechanism for magnetic fields. However, the planet Mercury suggests this process is wrong. Is it possible to propose a plausible alternative? The proposal here has both Earthly and Space components - it is still linked to the nature of, and motions in, the core plus it refers to the phenomenon of zero electrical resistance known as superconductivity as well as the recent discovery of gravitational waves. It also refers to the Moon's attraction on Earth's oceans, binary stars, the Sun's coronal heating and mass ejections, sunspots and mini ice ages, and black holes. A proposal that has support from only one or two sources may indeed prove to be correct. But surely support from several additional sources must greatly improve that proposal's chances of success. It's the goal of this article to be comprehensive in presenting its approach to the geodynamo. It's important to properly understand our planet's magnetic field because it protects us from the charged particles of the solar wind and cosmic rays. Without this protection from the magnetosphere, Earth would be stripped of its ozone layer that keeps excess ultraviolet radiation from harming life. And no magnetic field also means no atmospheric light displays called auroras, as well as no direction-finding compasses.

Candidates for the Slichter Triplet

Authors: Herbert Weidner
Comments: 5 Pages.

During the last 55 years, there have been many attempts to measure the three frequencies of the 1S1 self-resonance, the vibration of the Earth's core. One reason for this failure could be the insufficient reduction of the background noise, caused by the earthquakes. This is just another attempt to solve the ancient mystery. This time, perhaps with more success ;-)

Tidal Asymmetry

Authors: Raymond HV Gallucci
Comments: 16 Pages. Also published in the Proceedings of the John Chappell Natural Philosophy Society, Second Annual Conference, July 2016, University of Maryland

The Earth’s diametrically opposed, presumably symmetric, tides are due to the Moon’s differential gravitational force varying across the Earth. This is not intuitively obvious, but becomes clear when the physics is examined mathematically. The presumed symmetry is due to an approximation that holds when the radius of the affected body (e.g., The Earth) is much less than its center-to-center distance from the affecting body (e.g., the Moon). The exact solution indicates an asymmetry, which becomes more pronounced as the assumption loses its applicability.

Analyzing the 13S1, 13S2 and 13S3 Normal Modes

Authors: Herbert Weidner
Comments: 5 Pages.

The use of specialized filtering techniques allows the identification of three eigen­resonances of the earth near 4800 µHz, which are sensitive to the inner core. Careful programming prevents the formation of interfering intermodulation products and lowers the noise level. The accurately measured frequencies differ by about 1.1% from the PREM predictions.

Time Dependent Analysis of the 3S2 Normal Mode

Authors: Herbert Weidner
Comments: 7 Pages.

The time dependent analysis of the normal mode 3S2 near 1102.8 µHz allows a precise determination of the frequency and reveals a surprising phase modulation. This phase flip was first observed with the 10S2 normal mode and, by careless use of FFT, it may be misinterpreted as a frequency splitting. The correct demodulation requires the very robust method of homodyn conversion.

The Electromagnetic Signatures Produced by Earthquakes

Authors: Frank H. Makinson
Comments: 6 Pages. The effects created by the electromagnetic signatures produced by earthquakes need extensive additional study.

For centuries, there was no reliable way to know whether an earthquake was eminent, even though strange animal behavior and odd lights in the sky had been observed before earthquakes. It was noted that long range radio skip was interrupted before the 1960 Valdavia, Chile earthquake and the same interruption occurred before the 1964 Alaska earthquake. Scientists took notice, primarily outside of the seismology community, and began inquiring what mechanism could cause such an interruption. In the 1960s, it was already known that certain types of sunspot activity could cause the same type of radio skip alteration. It is now known there is a prodigious amount of electromagnetic activity proceeding and during an earthquake. It has been demonstrated in the laboratory that certain types of rock act like semiconductors when subjected to stress and produce an electric current that fluctuates. It is not known how many other earthquake related issues remain outside of our knowledge, especially the odd coincidence of human health problems just before and coincident to an earthquake.

Random Dynamics of Dikes

Authors: Han Geurdes
Comments: 19 Pages. Na

Inthis paper, random dynamic systems theory is applied to time series ($\Delta t=5$ minutes) of measurement of water level, $W$, temperature, $T$, and barometric pressure, $P$, in sea dikes. The time series were obtained from DDSC and are part of DMC systems dike maintenance program of the Ommelanderzeedijk in northern Netherlands. The result of numerical analysis of dike $(W,T,P)$ time series is that after the onset of a more or less monotone increase in barometric pressure, an unexpected relatively sharp increase or decrease in water level can occur. The direction of change is related to random factors shortly before the onset of the increase. From numerical study of the time series, we found that $\Delta W_{max}\approx \pm 0.5$ mNAP\footnote{NAP indicates New Amsterdam water level which is a zero determining water level well known in the Netherlands.}. The randomness in the direction of change is most likely explained by the random outcome of two competitive processes shortly before the onset of a continuous barometric pressure increase. The two processes are pore pressure compaction and expulsion of water by air molecules. An important cause of growing barometric pressure increase can be found in pressure subsidence following a decrease in atmospheric temperature. In addition, there is a diurnal atmospheric tide caused by UV radiation fluctuations. This can give an additional $\Delta P_{tide}\approx\pm 0.1$ kPa barometric fluctuation\footnote{1Pa=1Pascal=$1Nm^{-2} \approx 10kg s^{-2}m^{-1}$.} in the mid latitudes ($30^{\circ}N-60^{\circ}N$).

Interconnectedness and Geo-Compatibility: A Paradigm Shift in the Perception of Planet Earth

Authors: Sai Venkatesh Balasubramanian
Comments: 9 Pages.

Nonlinear Science has witnessed exponential growth in recent years, due to the enhanced ability it offers in understanding intricate patterns of system evolution. The present work purports to the application of such nonlinear analysis tools to obtain an enhanced perspective of the home planet earth. Specifically, nonlinear analyses of latitudinal and longitudinal altitude profiles reveal the presence of underlying chaotic dynamics and patterns. Interpretations of these results lead to the concept of interconnectedness of every location on earth to every other location, through space and time, where man and his evolutions and developments are seen as an integral part of nature’s transformation. Taking cue from this, the concept of “Geo-Compatibility” is introduced, given by the covariance of their chaotic signatures. Following this, Geo-Compatibilities of assorted location pairs are computed. From the results, it is seen that geographical similarities across and within continents show low and high Geo-Compatibilities respectively. However, the most interesting results are the high values of Geo-Compatibility obtained for pairings between Holy Sites suggesting that the development of civilizations and cultures, which are a result of man-nature interactions over hundreds of years, too possess intricate patterns. The entire work is thus a testimony to the concept of interconnectedness.

Nonlinear Analysis in Satellite Imagery of India

Authors: Sai Venkatesh Balasubramanian
Comments: 7 Pages.

The development of Satellite Imagery and associated analysis has opened up avenues in applications as diverse as meteorology, navigation, warfare and biodiversity. Motivated by this trend, the present article explores the application of nonlinear analysis tools such as entropy and fractal dimension in satellite imagery of the 29 states of India. It is seen that sharp and rich variations in terrain from green to arid or snow-clad mountainous regions contribute to high entropy, while rich variations in borders and varying scales of vegetation patches correspond to high fractal dimensions. The results obtained thus illustrate the significance and relevance of nonlinear analysis tools such as entropy and fractal dimension in satellite imagery.

A SpatioTemporal Rogue Wave Generator

Authors: Sai Venkatesh Balasubramanian
Comments: 4 Pages.

Rogue Waves are highly unstable waves extremely localized in space and time, appearing from nowhere and disappearing without leaving a trace. The observation of such waves in oceanography has led to increased interest in the physics community where optical rogue waves generated using microstructured fibers are studied for their interactions and the underlying physical phenomena. In the present article, an extremely simple rogue wave generator is proposed, where a hyperbolic secant based temporal profile evolves according to a hyperbolic secant square spatial profile. The derivative of this spatial profile gives the spatial evolution equation, and this is implemented using FPGA. It is seen that a single rogue wave exponentially rising to its peak amplitude at mid time instant and then quickly decaying is formed. The extremely simple signal-oriented design of rogue wave generator, effectively capturing the spatial and temporal propagation properties of such rogue waves, coupled with the potential applications it enables using the generated electrical rogue waves forms the novelty of the present work.

Cross Modulation Between 0S0, 0S2 and the Tides

Authors: Herbert Weidner
Comments: 8 Pages.

If strong earthquakes stimulate the earth to vibrate, a high-frequency amplitude modulation can be measured in addition to the exponential decrease in amplitude. The precisely defined modulation frequencies (sums and differences of known natural frequencies) can be explained by nonlinear laws within the earth. Four spectral lines may be generated by the movement of the Earth's core relative to the Earth's crust. Thus, the long-sought Slichter triplet could be identified.

Generation of Magnetic Fields in Cosmic Objects: Electrokinetic Model

Authors: Sergey G. Fedosin
Comments: 16 pages. Advances in Physics Theories and Applications, Vol. 44, P. 123 – 138 (2015).

Based on the assumption of separation of the charges in matter of cosmic bodies the possibility of obtaining the magnetic moment by these bodies is proved. The magnitude of the magnetic field appears proportional to the angular velocity of the body’s rotation and to the radius of convective layer. The periods of change of polarity of magnetic field of the Earth and the Sun are calculated by means of the size the convective layer and the convection speed. The solar activity appears the consequence of periodic transformation of the thermal energy into the electromagnetic form of energy.

Implementation of Single Fluid Volume Element Method in Predicting Flow Occurrence of One-Dimensional Geothermal Well

Authors: Sparisoma Viridi, Yusman Windra
Comments: 7 Pages. 8 figures

A finite difference based method known as single fluid volume element method (SFVE) is implemented into a simplified model of geothermal well. Two cases are discussed, where the former is when the well can not flow fluid and the later is when it can. In both cases the feed zone has the same 20 kg/s mass flow, but different shallow water temperature 40 & 70 °C, and pressure 1.0 & 5.4 MPa. There are two adjustable simulation parameters Δt and Δh which stand for time discretization and water volume element thickness, respectively. Influence of both parameters is discussed in the two cases for Δt = 10E-1, 10E-2, .., 10E-7 and Δh = 1, 2, .., 64. It is observed that each case has different numerical property to be aware of.

Dynamical 3-Space and the Earth’s Black Hole: An Expanding Earth Mechanism

Authors: Reginald t Cahill
Comments: 11 Pages.

During the last decade the existence of space as a quantum-dynamical system was discovered, being first indicated by the measured anisotropy of the speed of EM radiation. The dynamical theory for space has been under development during that period, and has now been successfully tested against experiment and astronomical observations, explaining, in particular, the observed characteristics of galactic black holes. The dynamics involves G and alpha- the fine structure constant. Applied to the earth this theory gives two observed predictions (i) the bore hole g anomaly, and the space-inflow effect.The bore hole anomaly is caused by a black hole (a dynamical space in-flow effect) at the centre of the earth. This black hole will be associated with space-flow turbulence,which, it is suggested, may lead to the generation of new matter, just as such turbulence created matter in the earliest moments of the universe.This process may offer a dynamical mechanism for the observed expanding earth.

Superconducting gravimeters are overloaded by strong earthquakes and stop the measurement.

Gravitational Condensation of Atmospheric Water Vapor

Authors: Fran De Aquino
Comments: 4 Pages.

Devices that collect water from the atmospheric air using condensation are well-known. They operate in a manner very similar to that of a dehumidifier: air is passed through a cooled coil, making water to condense. This is the most common technology in use. Here, we present a device that can collect a large amount of water (more than 1m3/s) from the atmospheric air using gravitational condensation. Another novelty of this device is that it consumes little electricity. In addition, the new technology of this device leads to a new concept of pump, the Gravitational Pump, which can be used to pump water at very low cost from aquifers, rivers, lakes, etc., and also to supply the high pressure (100atm or more) needed to push seawater through the semipermeable membrane, in the desalinization process known as reverse osmosis.

True Cause of the Tides Required Galileo, Newton and Kepler

Authors: Rodney Bartlett
Comments: 3 Pages.

According to “Galileo's Big Mistake” By Peter Tyson - Posted 10.29.02 (http://www.pbs.org/wgbh/nova/earth/galileo-big-mistake.html) - "It was in 1595 when Galileo, just shy of his 30th birthday, first came up with his explanation for the tides. The idea occurred to him while traveling on a barge that was ferrying freshwater to Venice. (Galileo lived in nearby Padua and often visited Venice.) He noticed that whenever the barge's speed or direction altered, the freshwater inside sloshed around accordingly. If the vessel suddenly ground to a halt on a sandbar, for instance, the water pushed up towards the bow then bounced back toward the stern, doing this several times with ever decreasing agitation until it returned to a level state. Galileo realized that the Earth's dual motion—its daily one around its axis and its annual one around the sun—might have the same effect on oceans and other great bodies of water as the barge had on its freshwater cargo. The key, as Galileo saw it, was that even though we don't sense it, different parts of our planet move at different speeds depending on the time of day. It's as if the Earth were a barge, which sped up, slowed down, and periodically changed direction.The chief objection to Galileo's argument was that his model should have called for only one high tide a day, whereas there are roughly two. Galileo explained this away by stating that many other factors play a role in creating a specific tidal situation. These include the length of a basin, its orientation, its depth, the shape of its coasts, the effect of winds, and so forth." I believe an idea of partly revised gravity requires the idea of Newton and Kepler that the moon causes the tides, to be joined with Galileo’s partly correct idea that the Earth’s movements slosh its water.

Safe Tunnelling in a Water Rich Shear Zone in the Western Ghats Threat to the Kerala-Tamil Nadu Water Bodies from the India-Based Neutrino Observatory

Authors: VT Padmanabhan, Joseph Makkolil
Comments: 14 Pages.

How will the Indian Department of Atomic Energy construct the biggest underground science laboratory in the world in a sheer zone in the Western Ghats, without repeating the hydro-geological disasters encountered in Gran Sasso in Italy, Rohtang in the Himalayas and Velligonda in the Deccan Plateau? This question regarding the negative impact of tunnelling of the India-based Neutrino Observatory on the nearby aquifers and surface water bodies in Idukki-Theni districts of Tamil Nadu, raised through peer-reviewed science, web and print media has been in the air since September, 2012. The State Governments of Kerala and Tamil Nadu ignored the issue and the Central cabinet has cleared the project. The first mega science project in India could have been launched after a detailed assessment of the short term and the long term impacts on the ecosystem. All reports should have been in the public domain, the pros and cons of the project should have been debated. This should have been followed by stakeholder consultancy at all levels. Without any of these, the Department of Atomic Energy and the Department of Science and Technology have decided to bull doze the Western Ghats with a million kg of gelatine.

Maximum Entropy Production and Resistance to Heat Transfer in the Earth-Atmosphere System

Authors: Hui-Hai Liu
Comments: 6 Pages.

To seek the thermodynamic basis for the well-known Maximum Entropy Production (MEP) principle has recently received considerable attention in the scientific community. However, a little success has been achieved in the reconciliation between the MEP and the currently existing physical laws. In fact, the MEP is not a fundamental physical principle, because it is not consistent with the minimization of energy expenditure rate (MEE) principle that has been supported by observations for water flow on the ground surface. A fundamental physical principle should be able to explain observations from different areas. To resolve the inconsistence, Liu (2014), based on observations from different geological systems, proposed a new thermodynamic hypothesis that states that a nonlinear natural system that is not isolated and involves positive feedbacks tends to minimize its resistance to the flow process through it that is imposed by its environment. He also shows that the MEP is actually a by-product of the minimization of heat transfer resistance in the Earth-atmosphere system under a relatively restrictive condition. This communication further derives that previous result in the more general case for the Earth-atmosphere system. The consistence between the thermodynamic hypothesis of Liu (2014) and Darwin’s evolution theory is also briefly touched on. All these support the validity of the hypothesis of Liu (2014).

Influence of Tides on the Earth's Crust

Authors: Allen Graycek
Comments: 4 Pages.

Abstract: Results of research so far indicate that convection currents likely do not play a major role in continental drift. [1] However, it is known that moon and sun tidal forces are sufficient to distort the shape of the planet and likely is the energy source for continental drift in the form of tidal forces. This concept outlines those tidal forces at work on the ocean’s ridges, such as the Mid Atlantic Ridge (MAR). Magma entering fissures plus flexure at the ocean’s ridges mechanically generates sufficient movement to force the crust plates away from the ridges.

Flattening of Earth's Poles

Authors: Nainan K. Varghese
Comments: 3 Pages.

Abstract: Flattening of earth’s Polar Regions and bulging of its equatorial region are usually attributed to ‘centrifugal force’ due to earth’s spin motion. ‘Centrifugal force’ is fictitious, yet it is assumed to physically affect earth’s shape. Earth’s spin motion is apparent only with respect to its own north-south central (spin) axis. With respect to absolute space, every point on earth continuously moves in same (mean) direction as the direction of sun’s linear motion, at slightly different linear speeds. Very small centrifugal action (due to differences in linear speeds of its constituent matter-particles) on earth is not sufficient to produce the observed magnitudes of equatorial bulge and flattening of its polar regions. This article intends to describe an alternative mechanism that causes observed physical deformation of earth.

Electric Volcanoes

Authors: Charles L. Chandler
Comments: 10 Pages. 10 pgs, 20 references, 6 figures

Significant anomalies in the fundamental conception of the driving forces in volcanoes are explored. It is unlikely that felsic magma would have the thermal energy necessary to melt its way through the thickest aspect of the crust above a subduction zone, without an unidentified heat source. And while mafic magma such as at Kīlauea flows through the much thinner oceanic crust, this has been explained as the outflow from a mantle plume, even though the seamount chain began in a subduction zone that is older that the postulated plume, and which is mutually exclusive with it. Hence subduction volcanoes are the primary riddle. A new heat source is considered: resistive heating from telluric currents. The significance is that it might be possible to prevent cataclysmic eruptions, such as at Yellowstone, by shunting the current into a new path, using a conductive borehole some distance away from Yellowstone, which would remove the resistive heating and thereby relax the pressure in the existing chamber.

Earthquake Precursors Based Upon Snap-of-a-Whip Effect.

Authors: Michail Zak
Comments: 14 Pages.

The objective of this paper is to analyze thermal anomalies associated with pre- seismic activities, to develop a model that explains effects of relatively fast appearance and disappearance of the ground temperature increases, and to apply that model to several hours prediction of the parameters of a potential earthquake. The approach is based upon the so-called snap-of –a-whip effect when an S-wave penetrates the upper soil/sand layer and releases its potential energy into heat at the very surface. This effect (that mathematically is equivalent to a snap of a whip) has been described by M.Zak, in [1], [2], and [3]. Special discussion is devoted to the inverse problem of prediction of expected earthquake parameters based upon observed time-series as well as to proposed experiment.

The Electromagnetic Signatures Produced by Earthquakes

Authors: Frank H. Makinson
Comments: 6 Pages. The effects created by the electromagnetic signatures produced by earthquakes need extensive additional study.

For centuries, there was no reliable way to know whether an earthquake was eminent, even though strange animal behavior and odd lights in the sky had been observed before earthquakes. It was noted that long range radio skip was interrupted before the 1960 Valdavia, Chile earthquake and the same interruption occurred before the 1964 Alaska earthquake. Scientists took notice, primarily outside of the seismology community, and began inquiring what mechanism could cause such an interruption. In the 1960s, it was already known that certain types of sunspot activity could cause the same type of radio skip alteration. It is now known there is a prodigious amount of electromagnetic activity proceeding and during an earthquake. It has been demonstrated in the laboratory that certain types of rock act like semiconductors when subjected to stress and produce an electric current that fluctuates. It is not known how many other earthquake related issues remain outside of our knowledge, especially the odd coincidence of human health problems just before and coincident to an earthquake.

Based on the assumption of separation of the charges in matter of cosmic bodies the possibility of obtaining the magnetic moment by these bodies is proved. The magnitude of the magnetic field appears proportional to the angular velocity of the body’s rotation and to the radius of convective layer. The periods of change of polarity of magnetic field of the Earth and the Sun are calculated by means of the size the convective layer and the convection speed. The solar activity appears the consequence of periodic transformation of the thermal energy into the electromagnetic form of energy.

Geothermal Well Behaviour Prediction After Air Compress Stimulation Using One-Dimensional Transient Numerical Modelling

Authors: Windra Yusman, Sparisoma Viridi, Sudjati Rachmat
Comments: Pages. IOP Conference Series: Earth and Environmental Science 29 (1), 012008 (2016); DOI: 10.1088/1755-1315/29/1/012008

The non-discharges geothermal wells have been a main problem in geothermal development process and well discharge stimulation is required to initiate a flow. Air compress stimulation is one of the methods to trigger a fluid flow from geothermal reservoir. The result of this process can be predicted by using by Af/Ac method [3] but sometimes this method show uncertainty result in several geothermal wells and does not take into account the time required for the process. This paper presents a simulation model of non-discharges well under air compress stimulation to predict well behavior and time process required. The component of this model consists of geothermal well data during heating-up process such as pressure, temperature and mass flow in water column and main feed zone level (based on several geothermal wells). One-dimensional transient numerical model is run in the Single Fluid Volume Element (SFVE) simulator [4] and the input data is read in to model. Based on simulation result, the geothermal well behavior prediction after air compress stimulation will be valid under two specific circumstance such as single phase fluid density between 1 – 28 kg/m3 and above 28.5 kg/m3. The first condition shows that successful well discharge and the last condition represent failed well discharge after air compress stimulation (only for two wells data). Discharge time is about 80 s or less, which is too short compared to a couple hours as observed field data. This models need to improve by updating more geothermal well data and modified fluid phase condition inside the wellbore.

How Masers Can Remove the Geostationary Satellites

Authors: Fran De Aquino
Comments: 4 Pages.

his paper provides a realistic approach to remove end of life geostationary satellites and GEO orbital debris into geostationary orbit (GEO), using ground-based masers. This method can also be used to put spatial probes and spacecrafts in orbit of the Moon, and also in orbit of the planets of the solar system, launching these artifacts from an Earth orbit.
