How to Use a Fishfinder: Advanced Tips and Techniques There are many successful anglers who use their gut to locate and catch fish, however using a fishfinder can open a whole new window to your fishing world. Modern day fish finders feature a host of features with amazing capabilities. Any fishing enthusiast can use a fish finder to locate fish with little difficulty because the technology will help clear the watery fog that alienates man from fish. However, it will take you some time to learn how

package is called the Remote Minehunting System. The system uses the Remote Multimission Vehicle (RMMV). The RMMV vehicle is produced by Lockheed Martin. It conducts autonomous and/or semi autonomous missions. It also carries AQS-20A minehunting sonar. The sonar attached to RMMV is specifically designed for a variable depth forward-looking and side-scanning under sea. Raytheon makes the AQS-20As. The RMS detects, classifies, and localizes non-buried bottom and moored mines. It also identifies shallow-water

Is it a girl or boy ? As a Ultrasound Technician you could be the one answering this or a host of other medical questions with help of ultrasound technology. The career of a Ultrasound Technician is exciting and beautiful , because you are there through the whole growth process of one’s child. The research will describe the career of a Ultrasound Technician, what is required to become a successful Ultrasound Technician and the impact this career has on society. In 1801 Thomas Young described “phase

sonar that ships use. How ultrasonography works is that a device placed on the body will release some high-frequency sound waves that will then record the sound waves’ echoes. As these sound waves bounce off of internal organs, they will intern locate the anatomical structures that are being examined (Batdorf and Lacy). Ultrasonography completely depends on the user, meaning that only a highly skilled and savvy professional can use this tool correctly (Finch). These professionals are referred to

Principles of Physics in Ultrasound Physics has become an important part of medicine allowing specialist doctors and radiographers to rapidly access a patient’s condition and to help in long-term diagnosis. This enables doctor’s to treat patients before their condition deteriorates. This procedure would not be possible without the use of X-rays, CAT scans, MRI scans, ultrasound and endoscopes, which allow doctors to see inside the body with little or no surgery

Dolphins are highly social animals that travel in schools. It makes sense that they would sometimes forage as a cooperative group. Several species have been observed to be group foragers. Some of these species include spotted dolphins, Clymene dolphins, and bottlenose dolphins. The species most associated with group foraging has been the dusky dolphin. Scientists have been trying to determine how many dolphins actually forage in groups, and how they do it. It is hard to concretely determine these

techniques were necessary to keep as much of our history intact as possible. This led to new ways of conducting these investigations, preserving as much of the materials as possible. Two such advances are ground penetrating radar (GPR) and side-scan sonar (SSS). Ground penetrating radar was first suggested not long after radar itself was patented, but was not widely available to the general public until the mid-20th century. The way it works is simple: electromagnetic radiation that exists on the

recently, advancements in SONAR have led to the creation of multibeam SONAR and side scan SONAR. Multibeam SONAR emits and receives sound over a large area, and allow oceanographers to create the most accurate model a seafloor, a Holographic survey. The time between when the SONAR beams are sent out and when they return is measured to model the ocean floor. While effective for deeper rocky bottoms multibeam SONAR does not function well in shallow flat bottoms. Thus side scan SONAR is used to model these

Active Denial System The Active Denial System (ADS) is an electromagnetic, directed energy, non-lethal weapon designed by the US military and built by Raytheon (Cumming, 2010). The ADS works by producing 95GHz electromagnetic radiation that is focused in a beam at a target (Wikipedia, 2014). These 3.2mm electromagnetic waves work on the same principal as a microwave oven. The waves excite water and fat molecules instantly heating them through dielectric heating (Wikipedia, 2014). Due to the extremely

Introduction Now-a-days Wireless communication is a part and parcel of our daily life. Underwater Wireless Communications is one of them. Many researches have been done since last two decade and still going on for getting more economy. The world’s oceans, sea, river etc has grab the 2/3 part of this earth. So, wireless information transmission underwater bears great significant. Goal Thesis Outline There are 3 major part of this thesis given below: First part consist background of underwater communication
