Abstract
The focal purpose of the Voyager Interstellar Mission has been to broaden the NASA exploration of the solar system further than the quarter of the outer planets and extend to the limits of the sphere of influence on the sun and even beyond. This expansive mission has been continued to characterize the environment of the outer solar system and has also assisted in search for heliopause boundary i.e. the outward flow of solar wind and the outer limits of solar magnetic field. Heliopause boundary penetration between the interstellar medium and the solar wind allows in measuring interstellar ...

Magnetism is the ability of a material to exhibit attraction or repulsion of certain magnetic materials due to the presence of magnetic fields. Magnetism may be permanent or temporary depending on whether a material is a hard or soft magnetic material. Magnetism arises from the existence of small atom-like structures referred to as magnetic domains that, when aligned, cause the effect of magnetism to be pronounced in a magnetic material (Huebener, 135).
Magnetism depends on the alignment of domains and in the same direction. As such, increase in temperatures results in increased random movement of domains, and hence affecting their alignment. On ...

Hall Effect sensors are transducers that respond to a magnetic field through varying their output voltage. They mainly consist of a thin piece of rectangular semiconductor like gallium arsenide passing a continuous current in it. They are used in current sensing, speed detection, positioning and proximity switching. They are also used many ignition distribution systems and monitoring of the engine rotations per minute. They produce an on off voltage signal that can vary from maximum to zero and then back to maximum (WMC 1).

Functioning

A hall sensor has three terminals or wires. One terminal is for the ground, the second terminal for ...

Introduction

Taking measurements may require the conversion of the measured quantity to electrical quantity. Transducers are devices or elements that perform this function by transforming physical quantities such as quantities like sound, light, or temperature into electrical signals like current, voltage, or capacity. Transducers consist of inputs, sensing elements, transduction elements, signal processing, and electrical outputs. The inputs known as the measurands are the quantities, states, or properties that are to be translated into electrical outputs. The sensing elements accurately measure these input energies and sends the information to the transduction elements to be transformed into the desired form. The ...

Introduction

At the centre of the solar system is the Sun. The nearest four planets are Mercury, Venus, Earth and Mars these are terrestrial and rocky worlds. The next four are Jupiter, Saturn, Uranus and Neptune these are gas giants. Between the orbits of Jupiter and Mars lies an asteroid belt that includes the dwarf planet of Ceres. After the orbit of Neptune, a disk shaped Kupiter belt exists where the dwarf planet Pluto exists and further beyond that there is a giant spherical Oort Cloud and the heliopause that is teardrop shaped (Choi).

Many ancient astronomers thought that the Earth used ...

Velocity Sensors:

Abstract:
In the monitoring and analysis of vibrations in industrial machinery and other devices, machine mounted sensors are of critical importance. There are three parameters representing motion that can be detected by vibration monitors, and they include velocity, acceleration and displacement. These parameters are mathematically related and therefore they can be derived from a variety of vibration sensors. Due to this relationship, the choice of sensor, whether acceleration, velocity or displacement is dependent on the signal levels involved and the frequencies of interest. This paper briefly explores and discusses the history, theories, and applications of velocity sensors as well ...

Magnetic Resonance Imaging or MRI refers to a technique of medical imaging that is used in radiology in visualizing in details the structure of the organs in the body. MRI utilizes nuclear magnetic resonance property to image the nuclei of atoms that are in the body. A patient lies within a powerful and large magnet where a strong magnetic field generated by the magnet is used to align atomic nuclei magnetization in the body. Radio frequency magnetic fields are then applied in order to systematically alter the magnetic alignment. This results to the production of a rotating magnetic field by the nuclei that can ...

1) A we know the image that we can see using ultrasound imaging systems is created by the reflection of the high frequency waves or echoes from the organs. Different organs have different velocities, so the reflection of the waves from these organs will be different, also the time between emission of the pulse and receiving the echo determines the distance between the organ which produced the echo and the transducer. Based on these datas the image is formed. As the velocity of the soft tissues and their place is different, different images will be created.

MRI is an imaging system that is applied in radiology in visualizing the interior composition of the human anatomy in fine details. The MRI process in medical practice uses the properties of magnetic resonance in creating images of the nuclei of the body cells and as a result it creates a detailed image of the body structure as compared to the X-rays. The MRI technique has had a rapid development within the field of medicine since the introduction of the early MRI equipment in medical care at the start of the 1980s. Consequently, by the year 2002, it is estimated that more ...

The aurora is a natural display of lights happening on the upper atmosphere, specifically, the magnetosphere, "the volume of space that surrounds the Earth" (Frequently Asked Questions about Aurora and Answers). It is a phenomenon that happens in the north and south poles, thus, the terms "northern lights" or the "southern lights. These lights are created when particles of the solar wind are sucked into the atmosphere with the help of Earth's magnetic fields. When this happens, the particles become energetically charged. As the "excited atom or molecule return[s] to the non-excited state [it sends] off a photon by making light" ( ...
