The Department of Physics at the Naval Postgraduate School recently collected data from a low-frequency vector sensor system off the coast of Big Sur, California, in May 2018. During the test, signals from numerous surface craft were recorded. In this study, a numerical model was employed to estimate the vector field transmission loss at low frequency in order to estimate performance of the system during the test. In order to provide realistic ranges of values, the impact of environmental...

A album of low tone drone experiments, trying to get extremely low tones, its not really spectacular or really great as far as the entertainment factor goes, but it's an interesting concept to listen to. Try turning your speakers all the way up with the bass eq all the way up. This album is just a bunch of extremely low rumbling drones, and ridiculously low frequencies.

The development of an ambient noise model for use in ice-covered Arctic waters is the primary goal of this research. The generation of ambient noise is considered to originate from large scale deformation of the ice cover (pressure ridge formation) which is caused on a synoptic scale by convergence of the ice cover due to wind stress/speed associated with the passage of Arctic storms. The Arctic Storm Noise Model (ASNM) has been developed as a dynamic model to predict the occurrence of extreme...

Offshore wind power plants are gaining importance in recent years, as there is adequate space available for its installation, high wind speed, no restriction on the size of turbine blades (no transportation and construction problem) and blades can be allowed to rotate at higher speed without any noise constraint, thereby increasing the rated power. However, the existing offshore wind farms face greater cost related challenges than those of onshore plants. The integration of offshore wind farm...

This study is focused on highly coupled multiple antennas with defected ground slot techniques. Two Printed Inverted-F Antenna (PIFA) are positioned at the top edge of chassis symmetrically. Both antennas are operating at low-band Long-Term Evolution (LTE) with center frequency, 829MHz. Rectangular defected ground slot is implemented to reduce the coupling effect between the antennas on the ground plane of the small chassis. Parameter study of the rectangular defected ground slot is studied...

Radiation from laptop cannot be seen by the naked eyes, but it can pose real dangers to our health. If only we are a few feet away to our laptops, otherwise when laptops are placed and used directly on our laps, it exposes us to quite more intense radiation that are harmful. It has been said that the amount of radiation emitted by desktop computers is generally higher than that which is emitted from laptop or notebook computers. And the use of small-sized components, a Light Emitting Diode...

The theoretical problem of predicting the effect of the propagation medium on the form or shape of the low frequency electromagnetic pulse of nuclear origin has been discussed in a previous paper. This paper presents some greater detail on this remarkable propagation phenomenon. Particular emphasis is placed on the construction of transforms (amplitude and phase of the propagation medium as a function of frequency) which can be employed to propagate theoretically almost any pulse shape. The...

The identification of acoustically active pressure ridges in the Arctic Ocean represents an important step in the development of a physics based, operational Polar ambient noise model. One method to accomplish this goal is through the use of satellite based remote sensors, specifically synthetic aperture radar (SAR).

The results of the work done under contract DNA 001-93-C-0146 are discussed. This work included changes and improvement to the long wave noise propagation code LNP, development of a new ground conductivity model for use in LNP and as a separate code. In addition, under this contract we demonstrated that LNP could be used in a system to forecast noise levels in a manner similar to weather forecasts. The techniques developed to do this are discussed.

As early as the year 2000, researchers had found that the activation peak of Chinese processing was in the middle part of the left frontal lobe (BA9); this area was less activated in studies of alphabetic writing; and even when there was activation, it was very weak. Since then, many Chinese studies have also reported activation in the left inferior frontal gyrus. However, the purpose of this research has mainly been focused on the semantic and phonological function of the middle frontal gyrus....

MODESRCH is a FORTRAN computer program designed to obtain rapidly, economically, and accurately, the mode constants needed to describe propagation in the earth-ionosphere waveguide at ELF, VLF and LF (10 Hz to 60 kHz). It is suggested that MODESRCH, along with required mode summing procedures, be used to replace 'waveguide' and 'wave-hop' codes currently used in network analysis programs which cover the ELF to LF frequency bands. This report contains a discussion of the analytical approach...

First, full-wave calculations are performed to assess the effect of a ledge of ionization in the 55-km to 65-km altitude range (e.g., C-layer) on long-path propagation. Second, relationships among wave frequency, incidence angle, and refraction heights are derived. (Author)
