Balloon Cars Essay Example for Free

Balloon Cars Essay Repulsorlifts as a Method of Stable Magnetic Levitation| Repulsorlifts were used in the study to find out if they can be used to replace the wheels of a conventional car. It was hypothesized that it will be able to lift a car using magnetic repulsion forces. The different magnets were tested individually with the usual tests for magnetic strength, size, and temperature increase, which were done in the preliminary testing. The prototype road and car were then constructed based on the specifications that had been identified after the preliminary testing. The prototype car’s magnets were permanent magnets while the road magnets were electromagnets. They had been oriented so that the magnets would repel each other.After the levitation tests, the proponents constructed other prototype roads and cars, based on the design which increased the chances for stability of the project. The repulsorlift setups were then tested for levitation. It was found that the repulsorlift was capable of lifting the car, yet its stability and lift would depend on two factors: the strength and the ratio of the strength of the car and road magnets, and the angles at which the car magnets are oriented. Therefore, repulsorlifts can be used as a method of levitation for cars once the lift would be sufficient to resist both gravity and the weights on the car.Further clarification of the procedures and results should be directed to the researchers and adviser.Researchers Earl Angelo B. Panganiban Cebu City National Science High School Cost-Effective Free Fall Apparatus| Cost-Effective Free Fall Apparatus for Elementary and Secondary Students. Public Schools do not have sufficient funds for the purchase of a Free-Fall Apparatus, which is used to measure the time for a falling object to hit the switch pad from a certain point. A cost-effective Free-Fall Apparatus was constructed with the aid of recycled materials to serve as a cheaper alternative for this device. This study was intended for the improvement of the original equipment in terms of materials used, structural design,  function and price. The main structure was built with the use of excess planks of wood. The electromagnet, powered by three volt-battery was assembled. Wires were tapped into the stopwatch and were connected to the electromagnet. The Power Supply Box was connected to the Synchro Box to allow relay function.The electromagnet was finally affixed to the device through the use of a large paper clip. A tape measure was fastened to the equipment. The switch pad was affixed through the use of a lever and magnet. The apparatus was tested for several times until it functioned accurately. The innovation proved to be very efficient. It showed the same function as the original one although the initial design was altered. Special features include the machine’s flexibility and added parts such as the lever. This apparatus can really be used by various public schools throughout the country because of its effectiveness and affordability.Further clarification of the procedures and results should be directed to the researchers and adviser. Para-Toluenesulfonate Doped Polypyrolle as EMF Electrode Source| A conducting polymer was synthesized from polypyrolle doped with paratoluenesulfonate (p-TS) using electrochemical deposition technique to find a substitute for metal electrodes in EMF sources. Samples were produced with varying p-TS molarity, specifically 0.1, 0.15, and 0.2 M. Initial characterization of samples was done using Scanning Electron Microscope(SEM) for surface analysis, and the Energy Dispersive X-ray system (EDX) for elemental analysis. Surface analysis of thin sheets was observed to be fibrillar, while thick samples had globular surface. Traces of Nitrogen, Carbon, Oxygen and Sulfur in decreasing order of concentration, were detected in the EDX system, showing potential as conducting material.To determine potential as EMF source, samples were subjected to Van der Pauw Measurement. Conductivity was found to be within 20 to 200 siemens, resulting in a computed resistivity of 0.05 to 0.005 ohms. These values are  comparable to those of certain conductors such as copper. When used in a chemical cell with copper and zinc sulfate solution, the EMF produced was between 1 to 1.5 volts. This showed that the p-TS-doped polypyrolle is a good conductor and could be a possible electrode of a battery. Thermal analysis yielded a peak of endothermic reaction at 350 ºCelsius. Degradation point was at 770 degrees celsius. The sodium para-toluenesulfonate-doped polypyrolle opens the prospect of creating lightweight batteries, since they are approximately 80% lighter than common metal electrodes used in EMF sources. This progress signals a breakthrough in plastic electronics.Further clarification of the procedures and results should be directed to the researchers and adviser. Elastomeric Grating for Wavelength Switching in Optical Communication Systems. A diffraction grating was fabricated from an elastic polymer. It was patterned after a plane reflection grating with a pitch of 1,200 lines/mm. It was characterized using HeNe laser to verify grating properties. Angular scanning as a function of applied strain was observed for two individual wavelengths. Intensity of the fiber output was optimized as an application of angular scanning in fine alignment. Beam profiles showed consistency of first order diffraction intensities at different levels of strain. This showed that the elastomeric grating’s efficiency is independent of strain. The elastomeric grating’s variable pitch can be of immense utility in optical communication systems.A stretchable grating can be used to replace typical high-cost architectures of metal or glass gratings of different pitches that correspond to various spectral regions. By changing the pitch, the grating can be used for different ranges of wavelength. The elastomeric grating’s variable pitch can be used to scan different wavelengths over a wide selection since elastomeric grating diffracts different wavelength division multiplexing in optical communication systems. Laser beams of different wavelengths carrying different signals can be transmitted simultaneously through an optical fiber and diffracted to route the wavelengths onto separate wavelength-specific channels.Further clarification of the procedures and results should be  directed to the researchers and adviser.

How to Write an Architecture Dissertation

How to Write an Architecture Dissertation Presented below is advice as well as general guidance about how to write an Architecture dissertation. Some of the advice and general guidance would be useful for the writing of any dissertation, whilst other parts of it are more specifically relevant for the successful completion of an Architecture dissertation. The purpose of this general guidance is to boost the over all grades received for the submitted dissertations. To begin with, always pay careful consideration to the exact title of any Architecture dissertation before starting to write it. The title of the dissertation can have a direct connection to the standard of the completed work, for better, or indeed for worse. The exact wording of any dissertation title is arguably more important than many students initially realise, and getting it right will increase the prospects for higher marks (if the student adheres to the rest of the guidance below). Indeed the finished Architecture dissertation can potentially be less relevant if the title is too complicated, too vague, or makes it surprisingly difficult to write a dissertation of adequate or appropriate length. Get the dissertation title right, and it is more likely that the completed Architecture dissertation will be concise, relevant, and therefore to the point. It increases the opportunity for the information, data, and diagrams within it answering the question or issue in the most effective manner possible. In other words just what the tutors, and the markers are hoping for. Lets face it nobody would like to have to read and then mark an Architecture dissertation that is as thick as a telephone directory and probably just as stimulating. Once a working title for the Architecture dissertation has been fixed upon the next stage is to commence planning the dissertation. Good or sensible practice is put a structure into place to make the Architecture dissertation better organised and therefore to keep the main subject of the dissertation in focus throughout the completed work presented to tutors and examiners. When dissertations are effectively planned they are more likely to be accurate, as well as being precise. When drafting the plan for the Architecture dissertation it would be sensible to include an abstract, a literature review, an introduction, two or three main chapters, a set of conclusions, and finally a full bibliography. The abstract and the introduction set the background and inform the reader / examiner / tutor how the issues raised in the Architecture dissertation title will be addressed in the rest of the dissertation. The abstract and the introduction need to have an impact, as they give the first impression of the Architecture dissertation. The literature review has the merits of informing the reader / examiner of how the information for the dissertation was gathered and used to shape the arguments and points made in the work. The content of the two or three main chapters is also extremely important as they present the bulk of the information, data, or contentions within the Architecture dissertation. Finally it is the arguments, contentions, and summaries contained within th e conclusions of the dissertation that could make or break the over all standard as well as the impression of the work. It is also worth making sure that the Architecture dissertation adheres to the relevant referencing system so as to avoid having to change it all after the dissertation has been finished. If providing tutors with draft versions of the Architecture dissertation any weaknesses or errors in the referencing system employed would hopefully be addressed at an earlier stage. After finishing the planning for the Architecture dissertation the next stage would be to carry out research in order to write a complete dissertation that will address the specific subject of the title and contain. From that point to then go on to contain the most appropriate as well as relevant information that could possibly be included is a sensible thing to do. Undoubtedly the best places to find the appropriate and thus relevant information to carry out the necessary research to successfully complete the Architecture dissertation are course books, academic journals, as well as the Internet. Course books, text books, and also specialist academic journals are the most likely sources to contain the pertinent information, diagrams, or data for a well-written Architecture dissertation, that is also straightforward to cite, quote, and reference properly. Caution should always be taken before citing or quoting information and data. Although the Internet can be an invaluable source of information due care should always be taken to ensure that online articles are actually accurate, properly referenced, as well as not been subject to copyright protection, which would leave the finished Architecture dissertation prone to allegations of plagiarism. When in the process of actually writing the Architecture dissertation various important factors need to be considered to maximise the opportunities of achieving top marks. For instance: What issues need to be raised, evaluated, mentioned, or covered either in full or in passing within the Architecture dissertation to make fully relevant, or appropriately detailed? Does the information, data, graphs, diagrams, quotes, or technical analysis within the Architecture dissertation assist in the answering of the question being asked? If such content does not make the dissertation better can it amended, improved, or even simply removed? Could the Architecture dissertation be re-worded, amended, or altered in any respect to more relevant, technically more detailed, and easier to read or understand? Would the adding a glossary of terms, or if applicable including Appendices at the end of the Architecture dissertation make it better to read and technically more informative? It would also be sensible to finish the Architecture dissertation earlier than the official deadline date set by tutors, and the Architecture faculty. The early completion of the Architecture dissertation would enable the whole dissertation, or the most important sections of it to be read by tutors, or anybody willing to proof read it for them to suggest amendments and improvements, or point out simple grammatical errors to put right. Tutors generally encourage their students to provide them with draft versions in order to improve the academic standard of the final version of the Architecture dissertation actually submitted.

K is for Killer :: Essays Papers

K Is for Killer Conflict is an integral part of a literary work. Many authors use conflict as a technique to help the reader feel exactly what the character is going through in he/she’s internal battles and struggles. Both of the fictional pieces, â€Å"The Fifth Child† by Doris Lessing and â€Å"’N’ Is For Noose† by Sue Grafton, contain significant conflicts between characters which are brought out through the use of many scenarios within the novels. The novel, â€Å"The Fifth Child† takes place in London during the late 1960’s. David and Harriet Lovatt are a happily married couple who reside with their four beautiful children in an enormous home on the grassy outskirts of town. The Lovatt’s are a close-knit family until the abnormal pregnancy and birth of a fifth child, Benjamin. Ben is a strong, loud, violent toddler with an appalling appetite. Besides his actions, Ben is also very different looking compared to the rest of the Lovatt children. Ben’s behavior and attitude begin to ruin the family to the point where each of the children are sent off to live with relatives and Harriet’s husband abandons her. Harriet is stuck with the internal conflict of choosing between her newest son and her husband and other 4 children. Harriet decides to get the best of both worlds by sending Ben off to a doctor to help control and correct his problems, so her family can return home and feel safe once again. Sending away her own flesh and blood starts eating at Harriet to the point where she takes Ben back home. She was astonished to find out that Ben had not gotten any better; he had actually gotten worse. Ben was now fascinated with the local town gang and was involved in many robberies, rapes and violent acts. Harriet feels like a failure as her attempt to regain her â€Å"perfect family† was destroyed. The literary work â€Å"‘N’ is for Noose† took place during the late 1980’s in Southern California. Selma Newquist, a run-down widow, hired a private investigator named Kinsey Millhone to find out the reasons behind the sudden death of her late husband Tom. Selma felt that something had been eating away at Tom right before his death, and she was nosey to find out what exactly it was so she could be at rest with herself.

Harry Houdini Essay -- Essays Papers

Harry Houdini What comes to mind when one thinks of Harry Houdini? There are many things one could say, magic, escapes, perseverance, hard work, determination, fame, etc. Houdini was a master magician as well as a superb escape artist. (Harry 1) Houdini was one of the most determined men in history. He was so obsessed with achieving his goal that no matter what got in his way he pushed it aside. Even if it were his parents he would ignore them. Many things got in his way but he was so focused that he ignored them. This is the story of the greatest Magician that ever lived. On April 6th, 1874 Ehrich Weiss (Harry Houdini) was born to Rabbi Mayer Samuel Weiss and his wife Cecelia on March 24 in Budapest, Hungary. (Timeline 1874 1) After Erich was born, his father had many problems in Hungary and came to Wisconsin. The Weiss family joined Rabbi Weiss in Appleton, Wisconsin, where he led a small Reform congregation. At age nine, Ehrich and some neighborhood friends establish a five-cent circus. Wearing red woolen stockings, he bills himself as "Ehrich, The Prince of the Air." (Timeline 1874 1) Harry Houdini lived a very rough childhood. His father had failure after failure. Since Weiss couldn’t survive in Wisconsin, he brought Erich with him to New York City. In the city, they lived in a boardinghouse on East Seventy-ninth Street. Ehrich works a variety of jobs to help support the family. In 1891, Ehrich teamed up with Jacob Hyman, a friend from his job at neckwear cutting firm. They form a magic act called â€Å"The Brothers Houdini.† (Timeline 1874 1) All his life Ehrich loved magic. One magician he especially admired was Robert-Eugene Houdin. Ehrich started calling himself â€Å"Harry Houdini.† The next year Eric experienced a grave tragedy. His father died on October 5, 1892 at the age of 63. (Timeline 1874 1) Ehrich was seventeen years old. He had experienced such a hard life that he just kept on going. Many people said that his childhood was the reason that he was so mentally strong and determined. Meanwhile â€Å"Harry† as he called himself now was performing on the Midway at the World’s Columbian Exposition in Chicago. Later that same year, Jacob Hyman left The Brothers Houdini and was replaced by Harry’s brother Theodore, or Dash as he liked to be called. That summer, Harry met fellow performer Wilhelmina Beatrice Rahner. After three weeks of getting to... ...(Timeline 1912 1) Later that year, the legacy of Harry Houdini ended as he died in Detroit on Halloween, from complications of appendicitis. Several days earlier, a student had struck him in the stomach in his dressing room, even though he was hurt, he refused to cancel his shows until it was too late. His death triggered mourning and tributes around the world. Houdini's funeral was held on November 4th at the Elks Clubhouse on West Forty-third Street in New York. As many as two thousand mourners packed the ballroom, and the event was widely covered. (Timeline 1912 1) In conclusion, I feel that Harry Houdini was the greatest Magician that ever lived. He was so talented that he was able to do more than just magic. He amazed people for years and was probably 100 years ahead of his time. Harry Houdini will never be forgotten for his achievements.

The Story of the Good Brahman

The Story of the Good Brahmas Based on my basic knowledge about Indian society, Brahmins hold the highest status in Indian's caste system. I perceive that the story will be similar to bible stories like, the good shepherd. However, what I encountered in reading the selection is a Brahmas, specifically, a confused Brahmas who Is not happy with his life. The Brahmas who Is a philosopher himself, constantly questions his existence, his essence, and his wit.He had all the luxuries, the wealth, and three beautiful wives but he is not happy with all f those. On the first look, he is much blessed compared to his neighbor who is very poor and imprudent. But his neighbor, the old woman is happy with her life. There goes the story of the old woman, who has nothing. She has no wealth, no knowledge, and no problem. She Just had enough faith In Vishnu and the Ganges River to wash herself every day. It seems that the old woman Is contented with her life even though she can see the glamorous living of her Brahmas neighbor.When the Brahmas was asked if he wanted to give up his wealth and knowledge for him to be happy, he effused as he doesn't want to be in the same condition as the old woman. He thought and believes that being means one has to be imbecile. After hours of reflection and re-reading of the selection, I realized that the story doesn't go around the story of the Brahmas but of both him and the old lady. I think that the title of the story Is inappropriate because It Is not all about the Brahmas himself. He Is not even a â€Å"good† Brahmas for me.I don't see any reason why the author should call him a good Brahmas. Yes, he is honest with himself and does not deceive anyone. But with all the blessings in his life, he doesn't know how to be contented. In the class discussion, the real reason why the old woman is much happier than the Brahmas was revealed. The reason was Ignorance. It served as a prison, a box for the old woman from questioning everything. She Is confined with her poor life without asking why she Is poor while the Brahmas Is rich. She decides to be Ignorant and be content with what she has.This box of ignorance made the old woman happy as she is not aware of what is happening in the society. This made her contented. Because of her ignorance, the woman is in Nirvana. On the other hand, the old witty Philosopher, have so much wealth but so much problem in his life. He is not contented with his life. Because of his wide knowledge, he also has more questions which could only give him problems In his life. If I were to choose whether to be the Brahmas or the old woman, I prefer to be the old woman in the case that she has peace of mind in her heart. But will not criticize or hate the Brahmas.I truly believe that we can be a pappy creature and at the same time reason out. Why would I be bothered and be problematic by the things that I cannot change and the things that I might never know? Also, If there's a means on changing my state by working hard, then I won't give up. I enjoy talking about many things with my friends. There are a lot of things that opinions and beliefs. Reasoning out doesn't mean that we have to be unhappy. It is a matter of perspective and each of us has a different level of contentment. For me, the greatest pursuit of all mankind is happiness.

Effects of Washington D.C Snipers

Effects of Washington D. C Snipers Two men that decide they want to take people’s lives into their own hands, can change the way American citizens live their everyday lives. This exact situation happened over a twenty-three day period, when John Muhammad and John Malvo went on a shooting spree in Washington D. C. John Allen Muhammad, a forty-one year old veteran expert marksman of the Persian Gulf War, was the main culprit of the crime. He was accompanied by John Lee Malvo, a seventeen year old Jamaican citizen. These two men killed ten people and wounded three others. The snipers had a strategic plan in shooting their victims. As appose to a random one day spree, they had a well thought out process of how to conduct this shooting. They cut a small hole out of the trunk of an old car. They used this hole to stick their gun out of and shoot people without getting caught, and without people knowing where the shooting was coming from. There were no particular people that they were trying to shoot. Everyone that was shot or wounded was random. They shot people picking their kids up from school, and people filling up with gas. This shooting scared people all over the community and throughout the nation. No one felt safe leaving their homes. Before the criminals were caught people were very cautious performing their everyday activities. Some people did not want to take their kids to school fearing that they, or their children might be in danger. The parents and children who did perform their everyday activities lived in fear every time Dial 2 they were in the open. This shooting also stopped people from wanting to get out of their car to fill up with gas. People also stopped going to the park, and even going out to run and exercise. People who had to walk to and from work were scared to go to their jobs in fear of being shot. Anytime people had to be out in the open, they felt as if they were a target. They were scared that somebody was always watching them through the scope of a rifle. Because the people did not know where the shooting was coming from, they did not know what warnings to look for. Once the shooters were caught, some of the tension was relieved. Even though some of the tension was relieved, some people still had the killings of innocent people in the back of their minds. Since someone had committed such an awful crime, they thought that someone else would commit this crime in a similar style. It took time before kids were out playing in the park again and people were back to their normal everyday activities. Because of this shooting, more cars are stopped and searched, because of small traffic violations to ensure the safety of others. More cameras have been put up throughout the city so cops can look at what happened after a crime has been committed, and hopefully bring the criminals to justice. During the time of big events, there are also more roads closed and blocked where all cars are stopped and questioned. Crimes like this also make it harder for the everyday citizen to buy a gun. It also makes people consider going and getting a concealed weapons license. Even today, five years later, people are still worried about crimes like this being committed. Some people feel as if they are a target every time they step out of their front door. Cops all over America have been trained to be able to spot suspicious behavior and know what to look for. The Government’s job is to make everyone feel safe, although this is not always possible because of similar situations from the past.
