—In this paper, we propose an approach to understand the driver behavior using smartphone sensors. The aim for analyzing the sensory data acquired using a smartphone is to design a car-independent system which does not need vehicle mounted sensors measuring turn rates, gas consumption or tire pressure. The sensory data utilized in this paper includes the accelerometer, gyroscope and the magnetometer. Using these sensors we obtain position, speed, acceleration, deceleration and deflection angle sensory information and estimate commuting safety by statistically analyzing driver behavior. In contrast to state of the art, this work uses no external sensors, resulting in a cost efficient, simplistic and user-friendly system.

This paper proposes a novel fuzzy-adaptive extended Kalman filter (FAEKF) for the real-time attitude estimation of agile mobile platforms equipped with magnetic, angular rate, and gravity (MARG) sensor arrays. The filter structure employs both a quaternion-based EKF and an adaptive extension, in which novel measurement methods are used to calculate the magnitudes of system vibrations, external accelerations, and magnetic distortions. These magnitudes, as external disturbances, are incorporated into a sophisticated fuzzy inference machine, which executes fuzzy IF-THEN rules-based adaption laws to consistently modify the noise covariance matrices of the filter, thereby providing accurate and robust attitude results. A six-degrees of freedom (6 DOF) test bench is designed for filter performance evaluation, which executes various dynamic behaviors and enables measurement of the true attitude angles (ground truth) along with the raw MARG sensor data. The tuning of filter parameters is performed with numerical optimization based on the collected measurements from the test environment. A comprehensive analysis highlights that the proposed adaptive strategy significantly improves the attitude estimation quality. Moreover, the filter structure successfully rejects the effects of both slow and fast external perturbations. The FAEKF can be applied to any mobile system in which attitude estimation is necessary for localization and external disturbances greatly influence the filter accuracy.

This paper falls into the category of ideas published and forgotten. It stemmed from one of the very few unidentified flying object (UFO) reports to have been published in peer reviewed physics journals. Its author, Bruce Maccabee, had suggested UFOs produce magnetic monopoles after (1.) analyzing magnetic site tracing data from Gulf Breeze, Florida and (2.) mathematically assessing Claude Poher's compilation of field strength data from the Chambon-la-Foret research station in France. Evidence supporting Maccabee's hypothesis was formed from (1.) unidentified aerial phenomena (UAP) reports about the behavior and site tracings of trees; (2.) similar magnetic site tracings from reports of an UFO crash in Southaven Park, Long Island, New York; (3.) analyses by Jacque Consiglio of impulse gravity reports by Evgeny Podkletnov, Giovanni Modanese, Claude Poher and Danielle Poher; and (4.) Keith Frederick's analyses of particle tracks in photographic emulsions. The merits of Maccabee's hypothesis were presented in terms of explanations for witness subjective sounds and vertigo; agitated animal behavior; tractor/repulsion beam observations; deactivation of missile launch protocols; and disruption of electrical systems associated with UAP. Recommendations were made for equipping field investigators with systems for measuring magnetic field vector and time-dependent properties and for collecting wood samples.

Detailed magnetometer investigations on road schemes have failed to identify the presence of particular monuments -notably large enclosure ditches -across the west of Ireland. An analysis of excavated evidence and an investigation of local soils, geology and rainfall data suggest that some type of monuments exhibit no discernable magnetic contrast that can be mapped by even the most sensitive archaeological geophysical instruments.

ABSTRACT: This paper will assess the most recently available open access high-resolution optical satellite data (0.3 m–0.6 m) and its detection of buried ancient features versus ground based remote sensing tools. It also discusses the importance of CORONA satellite data to evaluate landscape changes over the past 50 years surrounding sites. The study concentrates on Egypt’s Nile Delta, which is threatened by rising sea and water tables and urbanization. Many ancient coastal sites will be lost in the next few decades, thus this paper emphasizes the need to map them before they disappear. It shows that high resolution satellites can sometimes provide the same general picture on ancient sites in the Egyptian Nile Delta as ground based remote sensing, with relatively sandier sedimentary and degrading tell environments, during periods of rainfall, and higher groundwater conditions. Research results also suggest potential solutions for rapid mapping of threatened Delta sites, and urge a collaborative global effort to maps them before they disappear.

geophysical survey was performed at Ånestad in
Hedmark using two different techniques: the measurements
of topsoil magnetic susceptibility and the use
of gradiometers for detailed mapping of anomalies with
a magnetic contrast. The purpose was to gain increased
background knowledge in advance of planned archaeological
excavations. A special focus was on mapping
iron production sites and features related to these that
had not been indicated by a prior test-trenching scheme.
This article presents the results of these surveys and
compares the geophysical data with the excavation
results in order to critically evaluate the interpretations
made in relation to the geophysical datasets. The article
presents statistics derived from these comparisons and
discusses the potential and limitations seen from a
cultural heritage management perspective. About 65%
of all archaeological features detected were prior to the
excavation indeed interpreted as potential archaeology
in the geophysical data, including 29 out of 31 excavated
furnaces. The topsoil magnetic susceptibility revealed
the areas influences by high-temperature metal crafts
well and indicated areas of activity larger than the site
limits set in advance of the excavations. The gradiometer-
data showed that most shaft furnaces had a
prominent geophysical signature. There was a range of
detected anomalies, for which no recognizable source
could be found during the archaeological investigations.
Moreover, large rocks had comparable geophysical signatures
to the iron furnaces but could be distinguished
due to the larger size of the anomalies. The geophysical
results would probably have had a larger impact on the
project planning if they had been obtained prior to the
test-trenching scheme, instead of after.

Comprehensive geophysical studies (magnetometry, georadiolocation) were conducted in the estimated areas of ceramic production at Bolgar fortified settlement near Galankino Lake in 2016. Different geophysical study methods were applied with the use of various equipment were used, including a multi-antenna radar complex (MARK 300-8). Hearths were discovered and localized to the West, South and East of Galankino Lake. A single complex of hearts was studied with maximum possible accuracy using the geophysical methods. Then the production complex was archaeologically investigated at excavation 216. A reconstruction on the basis of geophysical data provided a high degree of identification of details and individual elements of production facilities and their general system within the study area.

Determining whether a magnetic anomaly detected at an archaeological site has a natural or a cultural source can be quite challenging in some regions of the world because of magnetic variability related to soil development and differing rock/parent material types. Though not consistently recognized, lightning is one major source for magnetic anomalies on archaeological sites that often has been overlooked and misinterpreted. A case study from the High Bank Works in south-central Ohio, USA shows the range of strike anomaly sizes, shapes, and intensities.

Magnetic fields generated by the brain or the heart are very useful in clinical diagnostics. Therefore, magnetic signals produced by other organs are also of considerable interest. Here we show first evidence that thoracic muscles can produce a strong magnetic flux density during respiratory activity, that we name respiratory magnetogram. We used a small magnetometer based on microelectromechanical systems (MEMS), which was positioned inside the open thoracic cage of anaesthetized and ventilated rats. With this new MEMS sensor of about 20 nT resolution, we recorded a strong and rhythmic respiratory magnetogram of about 600 nT.

Inertial measurement units (IMUs) are fundamental for attitude control of drones. With the advancements in micro-electro-mechanical systems (MEMS) fabrication processes, size, power consumption, and price of these sensors have reduced significantly and attracted many new applications. However, this came at the expense of sensors requiring frequent recalibration, as they are highly contaminated with systematic errors. This paper presents a novel method to jointly calibrate the accelerometer, gyroscope, and magnetometer triad in a MEMS IMU without additional equipment. Opportunistic zero change in velocity and position updates, and inclination updates were used in conjunction with relative orientation updates from magnetometers in a robust batch least-squares adjustment. Solutions from the proposed self-calibration were compared to existing calibration methods. Empirical results suggest that the new method is robust against magnetic distortions and can achieve performance similar to a specialized calibration that uses a more accurate (and expensive) IMU as reference. The jointly estimated accelerometer and gyroscope calibration parameters can deliver a more accurate dead-reckoning solution than the popular multi-position calibration method (i.e., 54% improvement in orientation accuracy) by recovering the gyroscope scale error and other systematic errors. In addition, it can improve parameter observability as well as reduce calibration time by incorporating dynamic data with static orientations. The proposed calibration was also applied on-site pre-mission by simply waving the sensor by hand and was able to improve the orientation tracking accuracy by 73%.

This report presents the results of magnetic gradient surveys covering 74.6 acres at the Great Circle and octagon of the High Bank Works earthwork site, a unit of Hopewell Culture National Historical Park in Ross County, Ohio. The Great Circle survey was conducted under contract with the Midwest Archeological Center and the octagon survey is the result of a collaboration between Ohio Valley Archaeology, Inc., the Cleveland Museum of Natural History, The Ohio State University, and Hopewell Culture National Historical Park. To date, all of the ground around the Great Circle (46.3 acres) has been surveyed and 28.3 acres of the fields containing the octagon have been covered.
The magnetic surveys have detected many anomalies of archaeological interest, including the main earthwork embankments, one probable and another possible small enclosure, feature clusters at the centers of the Great Circle and the octagon, and hundreds of possible pit and posthole features spread all across the survey area. Some of the possible pits, including several that appear to be especially large, fall along important lines of astronomical observation identified by Hively and Horn (1984).
The report concludes with a further discussion of the results and suggestions for additional work, including geophysical survey and ground-truthing techniques.

Neural speech decoding aims at providing natural rate communication assistance to patients with locked-in state (e.g. due to amyotrophic lateral sclerosis, ALS) in contrast to the traditional brain-computer interface (BCI) spellers which are slow. Recent studies have shown that Magnetoencephalography (MEG) is a suitable neuroimaging modality to study neural speech decoding considering its excellent temporal resolution that can characterize the fast dynamics of speech. Gradiometers have been the preferred choice for sensor space analysis with MEG, due to their efficacy in noise suppression over magnetometers. However, recent development of optically pumped magnetometers (OPM) based wearable-MEG devices have shown great potential in future BCI applications, yet, no prior study has evaluated the performance of magnetometers in neural speech decoding. In this study, we decoded imagined and spoken speech from the MEG signals of seven healthy participants and compared the performance of magnetometers and gradiometers. Experimental results indicated that magnetometers also have the potential for neural speech decoding, although the performance was significantly lower than that obtained with gradiometers. Further, we implemented a wavelet based denoising strategy that improved the performance of both magnetometers and gradiometers significantly. These findings reconfirm that gradiometers are preferable in MEG based decoding analysis but also provide the possibility towards the use of magnetometers (or OPMs) for the development of the next-generation speech-BCIs. I. INTRODUCTION Neurodegenerative disorders such as amyotrophic lateral sclerosis (ALS) may cause locked-in syndrome where the patients are completely paralyzed but remain cognitively aware. The brain may be the only source of communication for these patients. Brain-computer interface (BCI) spellers

The embedment of induction loop underground for traffic volume monitoring caused damaging effects to the road and reduced road surface aesthetics. A wireless magnetometer implanted underground in a small uniform area was developed to detect three-axis magnetic flux changes due to the perturbation of vehicle passing over the sensor. In this project, a wireless magnetometer sensor system operating at a radio frequency of 2.4 GHz for detecting and transmitting Z-field data has been developed to investigate the patterns of magnetic field associated with the car directions and speed. This is the first report in revealing the responses of the sensor to different car speed and sensing directions. Field tests were conducted by car passes over in a direction in-line or countering the X and Y axes of the magnetometer. The results showed that the strong magnetic field density as low as-100 to-230 μT could be generated when a car passed over the sensor in a direction countering X and Y axes. The speed detection limit of the sensor is < 60 kmph. The X, Y and Z flux patterns obtained is important in designing an algorithm for accurate detection and counting of vehicles.

Some of the principal experimental and theoretical results concerning metrological parameters of proton and Overhauser magnetometers are studied. In particular, the effect of operating modes, processing algorithms, sensor design and registration path on the absolute and random errors of geomagnetic field is discussed. The methods of testing and metrological certification used by the laboratory in producing magnetometers are considered in this report. In particular, the simplest laboratory testing, testing by means of special laboratory standard based on a magnetic shield, and the certification with a reference magnetometer under the conditions of standard magnetic field are described. The measurement systematic error resulting from the thermoelectromotive force generated at the polarization or in the presence of a temperature gradient is shown for proton and Overhauser sensors. Methods for this defect removal are offered.

In this thesis, the relationship between several high-latitude phenomena and the ionospheric conductance in both hemispheres is studied theoretically and experimentally. Theoretically, the high-latitude electrodynamics is studied by considering currents in the magnetosphere-ionosphere system resulting from the ionospheric sheet current redistribution between the conjugate ionospheres. It is shown that strong flow between the conjugate ionospheres, the interhemispheric currents (IHC), can

We have fabricated arrays of High-T c Superconducting Quantum Interference Devices (SQUIDs) with randomly distributed loop sizes as sensitive detectors for Radio Frequency (RF) waves. These subwavelength size devices known as Superconducting Quantum Interference Filters (SQIFs) detect the magnetic component of the electromagnetic field. We used a scalable ion irradiation technique to pattern the circuits and engineer the Josephson junctions needed to make SQUIDs. Here, we report on a 300 SQUID series array with the loop area ranging from 6 to 60 lm 2 , folded in a meander line covering a 3.5 mm Â 120 lm substrate area, made out of a 150 nm thick YBa 2 Cu 3 O 7 film. Operating at a temperature of T ¼ 66 K in an unshielded magnetic environment under low DC bias current (I ¼ 60 lA) and a DC magnetic field (B ¼ 3 lT), this SQIF can detect a magnetic field of a few picoteslas at a frequency of 1.125 GHz, which corresponds to a sensitivity of a few hundreds of fT= ffiffiffiffiffiffi Hz p and shows a linear response over 7 decades in RF power. This work is a promising approach for the realization of low dissipative subwavelength gigahertz magnetometers.

Coronal mass ejections (CME) are the primary cause of the highly disturbed conditions observed in the magnetosphere as measured by satellite or by ground based magnetic stations. Momentum and energy from the solar wind are transferred to the Earth's magnetosphere principally via magnetic reconnection that produces open field lines connecting the Earth magnetic field with the solar wind. The objective of this work is to infer some properties of the magnetospheric dynamics involved in the interplanetary magnetic field-magnetosphere-ionosphere coupling. Magnetospheric currents are coupled to the ionosphere through field-aligned currents. This particular characteristic of the magnetosphere-ionosphere interconnection is discussed on the basis of the energy transfer from higher (auroral currents) to lower latitudes (ring current). In this work the fast and sharp fluctuations observed in H or X components of the Earth's magnetic field are examined using a set of six magnetometers a...

This analysis was completed as part of a larger Modeling and Simulation effort to estimate algorithm-level Measures of Performance (MOP), such as the probability of detection (PD) and the probability of identification (PID) of a vehicle or person transiting through an area of interest. The present work focuses on MOPs for Unattended Ground Magnetometer Sensors, which may be used to detect passing vehicles and estimate their bearing relative to the magnetometer position. In the first phase of the analysis, we concentrate on the probability of detection as a function of vehicle speed and distance (i.e., point of closest approach (CPA)) from the sensor. In the second phase, we try to localize the vehicle by extracting its relative bearing with respect to the magnetometer from the two orthogonal induced magnetic field measurements. The derivations are based on the assumption that a road vehicle may be approximated as a prolate homogeneous ellipsoid, as well as the assumption of uniform linear motion. Results show that, for speeds below 30 MPH, the maximum detection ranges (for PD = 0.5) are on the order of 40 meters for two-axis fluxgate magnetometers and for the operational parameters used in this analysis. 1

This paper presents two simple approaches for fusing together motion and muscle (EMG) sensors to enhance control. The first approach fuses Gyro and EMG sensors to provide relative control, while the second approach fuses EMG, Accelerometer and Magnetometer for absolute control. A wearable prototype armband was developed which incorporates all the sensors. The armband enables any user with some level of yaw and pitch arm movements, as well as arm muscle voluntary contraction, to control an electrical device like a computer, a robotic arm, or a mobile phone. Simple data calculation from the motion sensors outputted pitch and yaw, while EMG threshold based techniques were used for a virtual enter button. The sensor fusion aims to create intuitive control, while not overcomplicating the design process. The interface was connected to a robotic arm and compared against other classical industrial control approaches.
