Career Episode 3 Scenario – 1 XYZ Ltd has the specialty to build and provide the maintenance for Underground communication equipments and recently they received the signal boosters having the problem with DC power supply and gain. You are working as a technician and your manager asked you to write down the report by testing two circuits and devices below by using different testing procedure and provide the detailed observation. P1.1 Your report/observation must contain the following information

Fluorescence measurement An Avalanche Photo Diode (APD) is used to measure this fluorescence signal using a confocal microscope The signal was defined as the integrated area of the fluorescent spectral curve. The titration curve of hybridization of the DNA-GNPs with complementary strand T1 is measured in order to find the optimal condition of the efficience of quenching. Various volumes of synthesized DNA-GNPs are mixed with 2.5 μL of 100 nmol/L T1. Each of these mixtures are diluted to 50 μL

Teenagers have dramatically evolved throughout the twentieth century. As they have changed, so have their attitudes. In the story, Among the Mourners, the protagonist Aurora, is seen as selfish and rude. She’s also shown as rather rebellious for her age. So where does she fit in? The early 1900s? The Late 80s? Or maybe even the 2000s? The early years of the 1900s were all related in some ways. The 1900s were a time where there was no real difference between the enjoyable youth of childhood and

The wand-lighting charm is a charm we discussed in lesson one. The wand-lighting charm is a simple spell that does exactly that: lights the tip of your wand. It is believed to be invented by Levina Monkstanley sometime in the 18th century. The incantation for the wand-lighting charm is lumos, pronounced loo-mos. The wand-movement is as simple as it gets, as it 's just a single counter-clockwise loop. Not much focus is required for this charm, since you 're not lighting an object, just the tip of

I must have said “Newton” at least fifty times already. “Are we going to Newton?” “How are we getting to Newton?” “How far away is Newton?” “Why are we in fucking Newton?” I sat squished against four other people in the backseat of a Mitsubishi Outlander, flattened against the window like one of those pressed pennies you pay 50 cents for at the science museum. That said, the driver was excellent at three-point-turns. It was kind of sexy. Six of us crowded five seats; the driver’s and passenger’s

Fitbit HR Review Fitbit HR is one of the popular wearable devices in the market today. It has the ability to keep you connected with yourself and keep track of your body activity using smart sensors. Fitbit comes in different shapes, sizes and color. It can be worn on the wrist and can help your achieve your fitness goals by track body activities such as heart rate, non of steps, calories and sleeping patterns. Features Fitbit HR records the usual statics with an additional feature of recording

Woodworking is a wonderful activity. If you are new to woodworking and looking to dramatically improve your skills, the key is education. You need to learn all of the top woodworking tips and tricks. By learning all of the best woodworking practices, you can avoid common mistakes and take your abilities to the next level. Starting up within the woodworking hobby could be extremely frustrating for some and simple as pie for others. It all depends on individual abilities. Set up your workshop with

Cree Inc. believed that LEDs have a potential to be the main lighting application market and made technological improvements in cutting production cost and increased brightness of LEDs. They had a disappointing financial results in 2007 due to market saturations and customers such as contractors, home residents, real estate developers and many more still prefer to use other types of light bulbs as it is cheaper for short-term period. Cree is very experienced with LEDs Research and Developments(R&D)

Abstract: The experiment compared and tested which type of incandescent lamp is more effective to provide the greatest efficiency on the tested solar cells. It was believed that halogen lamps will be the more effective light source and be more efficient due to less energy lost due to heat. Halogen lamps are a more efficient light source to use than tungsten lamps due to the higher efficiency percentages than their tungsten companions on solar cells. It tested the various power outputs through varying

Normally, if one would need to buy a laser diode and photodiode of a specific wavelength (1550nm or 1310nm), then it had to be bought internationally. This would have taken a long time to get. There were limited amount of laser diodes and photodiodes found in the lab, as some of these laser diodes and photodiodes cost around R2000.00 each. These components are very sensitive to electrostatic shock. By taking the cost into consideration, the laser diodes and photodiodes should be used with care. ESD

sample signal (Dolan, 2012). A light emitting diode is used as the light source in most RI detectors. A pair of photo diodes detects the light emitted. As the refractive index varies the photo diode light beam position changes so that more or less light shines on each diode. More light is struck on the upper diode. If there is a change in the refractive index, the light beam position may move down causing less light on the upper and more on the lower diode. The RI detectors are contained in an insulated

ABSTRACT:-Music has been a very common activity or hobby for entertainment among people. Among the most used music instruments, guitar has been a revolutionary instrument .The popularity of guitar based music had been on the rise in the earlier 1900’s. But suddenly in the mid of the 20th century, due to the inclusion of “Distortion” the rock music scenario achieved new heights. Now rock guitarists began intentionally "doctoring" amplifiers and speakers in order to create even harsher distortion.

The design relied on two Schmitt triggers to generate the two different tones while using the transistors to act as a switch. This causes it to trigger continuously between two unstable states, allowing automatic switching between two frequencies producing two different tones. The RC values between the two Schmitt triggers will differ. Capacitors charge and discharge faster when it’s resistance is smaller. Hence differing capacitor values allows oscillation between the two states. The transistors

The side effects of diode laser treatment include inflammation and redness. Photodynamic Treatment Photodynamic acne treatment requires the administration of a photosynthesizer. This is then activated to give a lasting result of less visible scars. This kind of treatment can

The problems are given as from the lectures review. (1) The code based on the zero cross correlation exist with in phase zero cross correlation between the user for high performance of system of optical network, is suffer from the long length of code in optical code division multiple access system. The cost of the is also very high for designing of code. Security of spectral amplitude code is also very low due the availability of information at every spectrum of code in optical code division multiple

DAC uses Nd YAG laser having homogeneous photothermolysis principle for removal of hair. Homogeneous photothermolysis is based on the fact that laser energy acts on a certain tissue volume homogeneously. Rapidly dividing cells with high cellular metabolism are the first to be affected by absorbed laser energy. The hair bulb cells in the anagen phase (period of active stable growth) have a high metabolic rate and are much more sensitive to heat. Surrounding tissue is preserved, while at the same time

I. Define The Problem To build a solar powered car that will gather enough energy to travel 700 miles on a sunny day in one full charge. II. Background Research Have you ever wanted to drive a car for a long period of time and never have to pay a dime? A solar powered car runs on solar energy and does not use gasoline. These cars can be electric and solar just in case the sun goes down. The best solar powered car has only traveled 600 miles on a full charge. The idea of this project is to
