Extract of sample "Methods Underwater Imaging"

 Uses and applications of underwater imagingUses and applications of underwater imaging 1. Performs spatial processing 2. Detects high-frequency signals 3. Converts high-frequency signals into image signals4. Displayed on the user’s screen. Beamforming:1. Combines signals in a linear manner 2. Spatially acquired by an array of sensors 3. Placed in the specific geometric configuration. Holographic acoustic imaging 1. Allows user to create dimensional acoustic image 2. Two-dimensional sensor arrays are required to accomplish it 3. The dimension collects data from sound waves 4. A three-dimension image requires a complicated computer algorithm and powerful computer that can analyze collected data
B). Uses of an underwater acoustic imaging system: it is used  To provide underwater inspection and observation capabilities  To classify objects  Observe details of an object when they form two dimension images on other objects by use of sound waves. Differentiating between both interesting and uninteresting objects in the ocean. For instance, differentiating rocks from mines and garbage from coral heads.   To provide underwater objects images when the water turbidity precludes optical viewing. C). The goal of underwater acoustic imaging   To locate and later differentiate various objects in water  Applications of underwater acoustic imaging. Used in:  commercial –underwater construction and fishing  Scientific  field-marine biology, archeology and oceanography Military field- intelligence collection, surveillance,  and mine reconstruction
The three methods have different roles in the underwater imaging process. In addition, the imaging process has specific uses and goals. More so, underground imaging is applied in the military, commercial sector, and scientific applications.     Read More

Crittercams and Positron Emission Tomography

...footage of habitats and animal habits that had previously not been thought possible. Another such technological tool is the Positron Emission Tomography (PET). A minute quantity of positron emitting radioactive material is ingested into the body, in such a manner that it reaches an organ or area suspected of being diseased. The emitted positrons are annihilated on coming into contact with electrons and the resultant release of pure energy is detected by sophisticated machinery. This provides an image of that organ or area, which is of significant use in diagnosis. PET has been of great help in diagnosing cancer, brain disorders and heart disease. It is an excellent non – invasive method for...

Imaging the gray hepatization stage. During gray hepatization, the disease-causing agent, and both red and white blood cells with the blood clotting substance fibrin consolidate inside the alveoli; and thus, giving off a gray appearance of the lungs upon viewing. Since air is prevented from entering the alveoli, exchange of gas is halted. Hence, dyspnea is apparent. Other more severe complications can result to this if condition is left untreated. The following images are presented to signify how the alveoli are prevented from functioning normally as they pus and other substance are accumulated inside them. Figure 3. The normal exchange of gases is interrupted by accumulated fluids (Badash, 2006). Figure 4. (a) Lobar...

...and essential concept, which has helped business organizations as an official communication intermediary in modern civilization. The concept of document imaging has been introduced in the business in order to minimize the physical effort of human. It has been observed that the traditional methods of storing paper and records required a higher rate of effort to manage the entire document imaging process. Moreover, it has been observed that more difficulties arise during the distributing and finding process. It can be further asserted that with the growing number of files, the difficulties in managing them also increased accompanied with significant time and effort consumption. The actual...

Underwater Performance Evaluation

...Underwater Performance Evaluation 1. Introduction Handstand, forward, and backward roll underwater techniques are some of the most difficult techniques in learning swimming[Dav04]. Learning these techniques, require proper attention and dedication. All the individuals that are involved in the training process should put all their effort[Cla04]. This paper measure the ability of a beginner to learn handstand, forward, and backward roll underwater. The paper will evaluate the effect a five sessions of training will have on the trainee. It is expected that the trainee will display better performance after each session of training. Once a swimmer acquires the basic skills in handstands,...
