• VR relies on a three-dimensional, stereoscopic head-tracker displays, hand/body tracking and binaural sound. VR is an immersive, multi-sensory experience. • Computer replications that use 3D graphics and devices such as the Data Glove allows the user to interact with the virtual reality. • Virtual reality refers to interactive, multi-sensory, and viewer-centered, three dimensional computer engendered environments and the combination of technologies that are required to build these virtual environments. Virtual Reality - Evidence for the Theory In the last years, the progress made in computer science technology has brought faster and faster computers to the market.
Therefore power quality will always be reduced not only from the common disturbance as listed but also power losses that could be caused by both nature and humans. Therefore, engineers comes up with ideas and solutions to overcome these problems. Based on case 1, engineers come up with TVSS to prevent the high voltage spikes to reach electrical equipment and Portable Motor Generator as temporary source to supply power in case of black out. For case 2, changing the cables to #4AWG or #8AWG cable will lower the chances of voltage drop according to the calculations
A VR headset is separately used by the audience to experience virtual reality in a 360 degree film and headset presents the images in such a way that the viewer’s brain is made to combine the images and experience a perception of three-dimension which adds realism to the movie watching experience. With the use of devices such as oculus rift (device that immerses the user in the virtual world) music can also be experienced through VR. The user can actually feel the vibration of the guitar thumping against the chest, the resonance of a piano’s soundboard along with the weight of the keys on the fingers. The user not just listens to the music stream but feels as if he were present at the exact location where the song is being
Virtual Reality is the buzz around these days. A very common question these days is "What is Virtual Reality?" Virtual Reality also known as VR is a three-dimensional computer generated environment experience in which the user can interact with the surroundings. This interaction is known as "telepresence" and it is this interaction that makes it unique. In other words, it is an environment created with special electronic equipment, which a user feels he is a part of without actually being there.
Virtual reality is created by artificial sensory experiences like sight, sound, touch and smell. Virtual Realities (VR) are used everywhere like in education, training, military, medical, entertainment and gaming purposes. VR is very helpful from training point of view, it allows professional to improve their skills without the consequence of failing the operation. VR is adopted by military and is particularly useful for training soldiers for combat situations and very dangerous environment where they learn how to react in an appropriate manner without risk of serious injury and death. Military uses VR in flight simulation, battlefield simulation, vehicle simulation, virtual boot camp, medic training etc.
VR allows the players to be more involved in the game as compared to the traditional gaming platform, it also highlights the emotional experience to an extent as VR makes the player feel as if their actions are responsible for a particular outcome. Especially with
The DMD is an MEMS device that has electrical input and optical output. Each DMD has up to 2 million individually controlled micromirrors built on top of an associated CMOS memory cell. There are two stable micromirror states (e.g +12° and–12°) for the DMD pixel, which the states are determined by geometry and electrostatics of the pixel during operation. As mentioned, the DMD pixel is an opto-mechanical element in that these two positions determine the direction that light is deflected. In other words, the DMD is a spatial light modulator.
Technology companies and scientists have a long believe that virtual reality will give rise to the next generation of personal computing, and change our way of lives forever. The latest problem encountered by the VR scientists is that high end headsets require extremely powerful computer to run the program, the computer will maintain in high working pressure for very long time, and also that it is painful to set up the VR system. Hence the VR enthusiasts feel that the cost is too high for them to use VR in gaming or videoing. Through the developing of VR technology, the scientists and developer finally came out with the solution. A solution called “inside-out tracking,” which uses sensors built inside the VR headsets instead of using outside
Electrical Faults THE control of grid-connected voltage source inverters (VSIs) under unbalanced voltage sags has been widely addressed in the technical literature. Some research has focused on active power control strategies, and two methods have been presented to provide the current references for the VSIs [1], [2]. As in the case of synchronous generators in conventional power plants, VSIs should remain connected during voltage sags and support the grid voltages with the injection of reactive currents [3], [4]. This is necessary to ride-through any type of fault. In electrical power systems consisting of generators, transformers, transmission lines and distribution circuits, most of the faults, about two-thirds, are liable to occur in the transmission lines.
CHAPTER 3 METHODOLOGY 3.1 Grid connected inverter The grid connected inverter is the power inverter connected between solar PV system and the grid. The grid connected inverter is mostly microcontroller based as it has various advantages of low cost and the in built pulse width modulation. The DC output from the solar PV system is converted into the AC and fed back to the grid. Due to the direct transfer of power from solar panel to transmission line through inverter eliminates the necessity of batteries and thus reduces the space, cost and maintenance cost of the system. When the solid state inverter introduced its control strategy makes the connection of solar PV system with the grid more feasible as shown in fig 3.1. nowadays the transmission system operators introduced the standard grid codes for the small, medium and large solar power plant to maintain the quality of the injected power into the grid with respect to their power rating so that the smooth operation without any complications will be possible the standard grid codes are given in the table 3.1, on other side the use of transformer is made mandatory by the national electricity regulatory authority for the isolation purpose [1] 3.2 Microcontroller based GCI
