A Neural Network Receiver for EM-MWD Communication
<p>Baseband digital communication in electro-magnetic measurement while drilling (EM-MWD) systems is often corrupted by non-white surface noise. The inability to reliably decode the transmitted signals in a noisy environment limits the depth at which EM-MWD systems can operate. Correlation …

Road vehicle recognition and classification using magnetic field measurement
… approach uses a roadside-installed, low-cost magnetic sensor and associated data collection system. The system measures magnetic field changes to count, detect, and classify passing vehicles into a number of vehicle types. We compare each vehicle using dynamic time warping (DTW), then extend …

WristQue : a personal sensor wristband for smart infrastructure and control
… activity, light, and color. A 9-DoF inertial/ magnetic measurement unit can be enabled to use the WristQue as a wrist-based gestural interface to nearby devices. Location and orientation data is used to implement a pointing interface that the user can use to indicate a device to control. This …

Archaeomagnetic Directional Studies Of Large Fired Structures In Britain
Archaeomagnetic directional dating of several Scottish sites has been undertaken by extensive sampling of large, physically stable vitrified exposures. Isothermal remanences and the demagnetisation patterns isolated using alternating magnetic fields and thermal methods, show that vitrification …

An ultra-high resolution pulsed-wire magnet measurement system
… (FEL) depends in part on the quality of the magnetic field in the undulator. Ideally the magnetic field on the axis of the undulator is transverse to the axis and sinusoidally varying due to the periodic sequence of alternating field dipole magnets. The resulting ideal trajectory of a …

Synthesis of Silicone Magnetic Fluids for Use in Eye Surgery
Stable suspensions of superparamagnetic cobalt nanoparticles have been prepared in poly(dimethysiloxane) (PDMS) carrier fluids in the presence of poly[dimethylsiloxane-b-(3-cyanopropyl)methylsiloxane-b-dimethylsiloxane] (PDMS-PCPMS-PDMS) triblock copolymers as steric stabilizers. A series of the …

Lanthanide-based single-molecule magnets: A rational design by chemical intuition
… theoretical tools to investigate the dynamics of magnetic properties of the Dy1 and compared with the theoretical results for Dy2 to gain insight on the contribution of covalency, crystal field effect and the role of aromaticity in stabilizing the excited magnetic levels of a single-molecule …

Vectorial Magnetic Properties Measurement of Electrical Steel under Triaxial Stress and Different Temperature Conditions
Electromagnetic devices, such as electrical machines and transformers, play crucial roles in electrical energy conversion and transmission. As the focus on global warming and carbon emissions grows, reducing their losses and improving efficiency has become a top priority. However, designing …

Synthesis and characterisation of Aurivillius phase materials
… and rotations of the BO6 unit. Substitution of magnetic ions such as iron and manganese at the B-sites has been shown to produce room temperature multiferroic materials. Magnetic coupling between ions requires proximity between the magnetic ions. The work presented in this thesis involves an …
