Fresh Perspective for Marine Electrical Distribution Free Essay Example, 4250 words

Direct current (DC) is an alternative to alternating current (AC). Electronic circuits are mostly operated and run by low-voltage DC, and this is applicable and ideal for equipment and machines in large ships. A direct current is also produced by an electronic circuit, with capacitors, resistors, and transformers, to convert the alternating current. DC has many advantages compared with AC. One of the most significant advantages is the absence of inductance losses and harmonic problems. Certainly, DC systems would be preferred over AC systems if the advantages of AC devices such as transformers, three-phase induction, and synchronous machines were not present. AC electromagnetic machines do no face any real competition because of the poorer performance and higher maintenance of any such alternatives. AC electromagnetic machines are unlikely to be replaced with anything having compatible performance characteristics in the near future. The combination of an electric generator with a di esel engine or a gas turbine is perhaps the most effective way to produce electrical power for the foreseeable future. DC generators no longer have a real place in large marine electrical systems, as they are heavy, expensive, and can provide only limited voltage, imposed by the limitations of commutators.

Aerospace Engineering - 1588 Words

Aerospace Engineering has paved the way for a vast majority of today’s modern technologies; it has contributed to the research and development of stealth, reconnaissance, and commercial aircraft. Aerospace engineering has made revolutionary breakthroughs in the development of both fighter jet and rocket designs, including pilot/passenger safety, thus forever changing the outlook of travel and warfare. One might ask; what is Aerospace engineering? Aerospace engineering is the branch of engineering that contributes to the design, development, and production of aircraft or related systems such as rockets, spacecraft, and missiles. Aerospace engineering is closely tied to aeronautical engineering and†¦show more content†¦This leads to the development of stealth and reconnaissance aircraft. Stealth aircraft are commonly coated with a special poly graphite skin. This allows for the aircraft to absorb and deflect radar signals, much like the Earth’s atmosphere absorbs and deflects radiation. The abilities of a stealth aircraft are somewhat limited to an extent that it cannot engage an enemy in a dogfight proficiently, meaning it’s offense is better than it’s defense especially in the case that the enemy is a ground target. Another limitation to the stealth’s design is that once a stealth fires it’s weapons or releases a payload it becomes visible to conventional radar systems. A closer look into how these nearly invisible aircraft become as bright as day on radar; stealth aircraft along with some reconnaissance aircraft have internal armament which means that each time a weapon bay opens to fire its payload the non-insulated weaponry becomes â€Å"exposed†, in turn the radar and infrared signals are able to bounce off the exposed area and reveal a portion of the stealth as well as record it’s position. Reconnaissance aircraft do not rely on stealth as much as a traditional military radarShow MoreRelatedAerospace Engineering Essay1361 Words   |  6 PagesAerospace Engineering has paved the way for most of modern day technologies; it has contributed to the development of stealth, reconnaissance, and commercial aircraft, its made revolutionary breakthroughs in both fighter jet and rocket designs including pilot/passenger safety, forever changing the outlook of travel and modern warfare and travel.

Ban Sugary Foods Should Not Be Removed - 757 Words

Some argues that currently, almost one third of Americans are obese and obesity rate is considered as sum serious nation epidemic trend, and is thus, associated with 300,000 individual’s death each year. While there have been numerous debates on whether to ban sugary foods, sodium products in the vending machines at schools, not many realize its cost of regulating such products; and its effect to civilians due to the cost associated with it. Upon performing my research on numerous articles, it is thereby agreed that unhealthy food should not be removed. Moreover, throughout my research it has come apparent that healthy foods are generally expensive, and their availability is limited. Instead of depriving consumer’s choices and focusing on small-scale changes, the government should focus on the educational side of teaching awareness and implement new food policies to meet meal standards revised by the officials. Considering the rate of obesity and its consequences of in-taking poor nutritious foods, it is comprehensible as to why there is a necessity of removing junk foods. However, a complete restriction on food that does not satisfy the federal standard is a bad idea stated by Sherri McGinnis (2014). In addition to her statement, the study also found that the removal of low nutritious food could potentially increase consumption rates of such from vending machines, a la carte lines, because students can still purchase anything they wish to consume through an outsideShow MoreRelatedEliminating Sugary Drinks And Foods From The Mayo Clinic Campuses1147 Words   |  5 PagesEliminating Sugary Drinks and Foods from the Mayo Clinic Campuses WARNING: Drinking beverages with added sugar(s) contributes to obesity, diabetes, and tooth decay.

The Phantom of the Opera free essay sample

In the Phantom of the Opera, Erik is ill famed for turning Operas into disastrous slaughterhouses and everybody fear and dislike him for that. He makes ridiculous demands and every single one of them is met accordingly; for if his demands were not met, he warns the Opera owner of the fatal consequence he could inflict. The Opera’s owner is terrified and is compelled to sell of his property, so as to avoid any contact whatsoever with this shadowy figure. But the Phantom just does not stop there and because his judgment of right from wrong is impaired, he actually goes on to cut off the chandeliers when he gets angry at the managers and let his temper get the best out of him. This little expression of anger as perceived by the Phantom is not so little, as 25-50 people lose theirs lives. Now judging from that, it becomes lucid why Raoul or anybody would now have developed an intense feeling of hatred for and fear of the Phantom. We will write a custom essay sample on The Phantom of the Opera or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page But He continues his nightmarish ventures and goes on to kill Firmin because he was doing his â€Å"Christine† a favor. He does not have that sense of awareness or better still, that sense of right from wrong to tell him that he was not supposed to murder somebody in order to help somebody out. But Then again, you can’t be too harsh on the Phantom, for the facts that He is badly disfigured and mentally impaired. Judging from his lack of perception, his crime of killing Firmin may seem justifiable, because he does not know what to do in the kind of situation he found himself in. He deeply loved Christine (whom he thought he had given the beautiful voice to and therefore was responsible for Raoul’s love for her) and was not about to let any thing hurt her. But the lack of judgment is just one of his weaknesses that makes you want to sympathize with him and not label him as a simple cold blooded murderer. His other weakness lies in his physical appearance; he seems to be self-conscious about his appearance when he tells Christine about no body wanting to like him and being denied of motherly love. And it is upon this rejection; he goes on to blame his killing on fate and how he was destined to be that way. When he reveals that side of himself to us, we have no choice then but to sympathize with him. In final analysis, the Phantom no doubt is a scary sight to look at, and also a cunning and lethal character to take for granted. He uses his cunningness and craftiness to manipulate and murder people, and for that, he gets his well-deserved hatred from audiences. And a premeditated and voluntary murder can in no way be justified. But on the other hand, he is just another vulnerable character provided with the wrong choices and circumstances in life. And instead of turning that negativity into something positive, he chooses to be hidden from society as whole, thusly working against humans in general. With these two focal points being established, I must say that I am forced to loathe him for killing innocent people and sympathize with him for not being offered a good hand in life.
