thickness of subcutaneous fat. The BodyMetrix BX2000 A-mode ultrasound is used in conjunction with associated body view software in order to observe and record these fat measurements. As with any other diagnostic ultrasound, gel is applied to the transducer and moved back and forth; it is important that minimal pressure is applied as this could compromise the true thickness of the subcutaneous fat. This procedure is used for both coaches and the athletes themselves to track fat loss, muscle mass…

3.3 DEMERITS Cost comes first in considering the demerits of optical fiber networks. Despite of the fact that the cost for fiber is dropping by 60% per year and is beneficial in long run, its initial installation cost is still high and is not affordable to all vendors. Per unit cost of fiber cable is more than that of copper cable. Secondly, as the technology is still new and improvising, it requires skilled manpower for its installation, operation and maintenance. Further it requires new…

Design and Simulation of Microcantilevers for Sensing Applications Abstract- MEMS is the integration of active and passive elements on a single chip, which combine electronics, electrical as well as mechanical elements to use in sensing and actuation. MEMS technology used in sensing applications with use of basic mechanical elements such as microcantilevers, beams, diaphragms, springs, gears and so on. In this research paper, microcantilevers are used as basic elements for design of Sensors.…

Time Effects on Sensory Modulation, it was apparent that the point of the experiment was to investigate the differences in memory recollection subsequent to the presence of various visual stimuli. The study involved the usage of an EOG and an EDA transducer that were attached to my body accordingly before the study was initiated. The purpose of these devices were to monitor the change in muscular electrical activity around the eyes in order to keep track of blinking rates in addition to any…

with the moving arc of the stress test acting as a guideline. Methodology Ultrasonography is the method that was used for purposes of assessing 70 asymptomatic baseball pitchers’ UCL while undergoing spring training. In addition, a linear-array transducer which is 15-MHZ was used in capturing both dominant and non-dominant images of the elbow. Paired t-tests were used with the average of rater values in order to determinant the significance that exists between non-dominant and dominant elbows.…

Imaging today is more sensitive and effective at detecting masses than in the decades before, and has proven to be a reliable and safe method of evaluating breast tissue. Breast Ultrasound of the Past and Present In 1951, Wild and Neal used a 15 MHZ transducer to record and describe the acoustic impedance signatures of malignant, benign, and normal breast tissue. (Dempsey) This study paved the way for continuing improvements in breast ultrasound. From the 1970’s to the 1990’s, breast…

input signals to a voltage, current or charge. This information will be gathered by a system connected together using wired, optical or wireless instruments. Based of the information gathered the system will output an electrical output to a transducer. A Transducer will then convert the electrical…

Ultrasound has been used for many years to help diagnosis. Ultrasound describes sound frequencies beyond the range of normal human hearing and 20 kilohertz. Ultrasound uses focused low-energy ultrasound waves to visualize the interior of the body in a noninvasive and painless way. Many people are to thanks for the evolution of ultrasound. Dating back to the 1700’s. Lazzaro Spallanzani in 1793 observed that bats function efficiently in the dark, even when blinded, but not if deafened. He…

For a long time back, the vast majority were passing on the grounds that they didn't comprehend what the reasons. A few people had numerous issues with kidney, others with livers, and mind. For a long time back, they didn't have any improvement machine can find or treat the reasons why individuals were kicking the bucket. Numerous pregnant ladies had numerous issues and analyze possibly lethal or incapacitating anomalies in the hatchling since they didn't know why. Today, we will take care of…

The history of piezoelectricity evolution is over 120 years which was discovered by brothers Curie in 1880. They were Pierre Curie (1859-1906) and Jacques Curie (1855-1941). During the study of the generation surface electrical charge by applying pressure on some material, they found out an unusual phenomenon which was a voltage of opposite polarity was generated by pressure was applied on the crystalline minerals such as quartz. The amplitude of the generated voltage was proportional to the…
