Fiber optic sensor

A ray of light travels in a straight line. This is true until it passes from one medium (eg. air) into another medium (eg. glass) of a different optical density. When this happens, the ray of light changes speed causing it to bend either towards or away from the normal which is an imaginary line at 90 to the interface between two mediums. This is called refraction. How much it bends depends on the refractive indices of the two mediums which is a ratio of the speed of light in one medium…

1.1 Overview of aerospace industry Globally, 3.57 billion passengers travelled on aeroplanes during 2015 and the demand for air travel is predicted to keep rising.1 As the frequency of air travel is increasing, it places a pressure on the aerospace industry to improve material performance and the efficiency of their transportation.2 Classically aircraft were constructed from metallic materials such as aluminium and titanium. Therefore, new materials must have specific properties and…

Does High Fiber Diet prevent Asthma? Overview Yes, specifically, a diet full of vegetables and fruits can help minimize the level of asthma and allergies in the human body. Asthma is caused by cold, infection, dust, and stuffy areas among other factors. A person suffering from asthma is proved to have an easy time as long as he/she is feeding well in a high fiber diet. Asthma patients need a lot of care since the condition is not that easy to deal with. In case you are dealing with such a…

1.1 Introduction This chapter will briefly discuss the background of Software Defined Networking (SDN) and its use in Wireless Sensor Networks (WSN). It will also state the Problem Definition, the Aims & Objectives of this project, and the Methodology used to achieve those objectives. In the end, it will present an overview of the dissertation’s layout. 1.2 Background The Internet has made an enormous impact on the world of communications. It has interconnected billions of networking devices…

WIRELESS SENSOR NETWORK (WSN): Wi-Fi sensor networks (WSN), once in a while called wireless tool and actuator networks (WSAN), are spatially disbursed autonomous sensors to monitor bodily or environmental situations, which include temperature, sound, pressure, and so forth. and to cooperatively pass their expertise through the network to a major location. The extra brand new networks are bi-directional, additionally sanctioning control of device activity. The improvement of wireless…

Every robot is connected with numerous sensors which help in automating the whole process. So, once the robot is programmed for a specific task, the sensors then continuously monitor the task being undertaken by the robot and help the robot to perform that task optimally. These sensor values have to be monitored continuously by a system. The system consists of controllers and processors which process the data provided by the sensors and then send control signals to the robots. Now, big…

of the operation of optical fibers. Just by altering and controlling the angle at which light is incident on the fiber, we can transmit this light signal efficiently. By this principle of Total Internal Reflection the ray of light is trapped within the denser glass of the center of the composite cylindrical glass fiber, the core as if it is guided down the core in a zigzag path of successive reflections. These light waves are guided through the core of the optical fiber just like a radio…

Uses for fibre optics The most common form that optic fibre technology is found in is cables. These cables have revolutionized technology, telecommunications and even medical. Uses of these cables range from telephone and internet cables that are able to run across the Pacific Ocean to military uses in tanks and drones used in combat. The cause for this is due to the advantages that the cables have. In a quick sum up they are lighter, faster and more secure. People are able to send international…

Over the past few decades, increasing research and development efforts toward value addition and efficient utilization of nutritionally rich agro-industrial residues have been gaining attention around the world. Several industrial residues, such as whey, sugar beet pulp, cassava bagasse, apple pomace, citrus waste, coffee pulp/husk, etc., have been studied as model system. They are either used as microbial substrates in fermentation or are subjected to the extraction of bioactive molecules1-4.…

through October fifth I created a food log to help me further analyze my diet. I noticed that my diet is lacking dietary fiber, potassium, iron, magnesium, vitamin A, D, and choline. I was able to know this by logging my food every time I ate on a website called SuperTracker where it can tell you the food sources you’re missing along with your activity levels. Dietary Fibers primary role in the body is to strengthen the walls and to regulate digestion. I don’t have enough of it in my diet but…
