Love and Ritual in Christianity - Essay Example The Bible is the Holy Book Christians use to venerate and has been utilized as the manual for regular daily existence. There are ceremonies and celebrations that mark the way where Christians acclaim God (Pecklers 65). These ceremonies exchange back to the merriments that are found in the Bible, and right up 'til the present time, numerous people despite everything maintain the practices. In any case, relatively few individuals see these customs as a method of love. They see it is crude and void. Some go similarly as proposing that there is no Supreme Being to adore. This paper, notwithstanding, will inspect love and ceremonies that mark the Christian confidence, and why it is essential to live having confidence in something. Void formality is the way toward experiencing, or playing out a custom while there is the nonappearance of genuineness or veritable significance. A great deal of this occurs in numerous territories as people accept that they are doing this to fall in God’ s favor. This, to countless individuals, is what is called formality (White 61). It is generally done to recoup some feeling of strict inclination that was once lost. This isn't approved in present day Christian settings as it emits a sentiment of love being damaged. At whatever point the example of love is damaged, individuals realize that the plan implied for custom isn't being followed. This gives the religion a horrible notoriety among different religions that exist. Christians pride themselves with the idea of their religion being better than other existent religions. They, in this way, follow the vast majority of the customs in the Bible carefully to comply with the methods of truth. In the Holy Book, the New Testament ways are picked over the Old Testament ways. This shows a portion of the customs that were once completed; need never again be done after the happening to Christ. He came to reveal insight into how Christians could live without a portion of the old conventions t hat governed their lives (White 64). In that capacity, cutting edge Christians follow the New Testament to direct them in regular daily existence. That is the reason; forfeits and consumed contributions are not part of the ceremonies Christians do in present day time. They, nonetheless, despite everything watch a portion of the ceremonies in the Bible. Likewise with any religion, there will undoubtedly be bunches that decide to do things any other way. This is as per how they see and understand the Bible. This is most likely why there are various gatherings of the Christian religion, which decide to be not quite the same as others. This is through the way and way of love, and leading of their customs. Every one of these gatherings see the different as an invasion of the genuine Christian religion. What they don't appear to acknowledge is that every one of these gatherings fill a similar need, and a similar God (White 76). Christians adore consistently, and the year. Despite the fact that, the styles of love vary in all the sections present, the administrations, adore services, and customs, hold uncommon importance to Christians. Christians accept that the congregation is the residence of God. This is the place they lead their administrations. Huge numbers of the devotees revere on Sunday as they trust it is the Sabbath, the day that Jesus rested. Others, for instance, the Seventh Day Adventist, accept that Saturday is the honored day. This doesn't make them any less Christian than the Catholics, who are viewed as the establishment on which Christianity is assembled. There is the utilization of workmanship and design in these various divisions (White 76). The utilization of expressions and beautifications shift as they represent diverse importance and imagery in these spots of love.

How To Produce A High School Newspaper Essays - Journalism

The most effective method to Produce A High School Newspaper Essays - Journalism The most effective method to create a secondary school paper I sat anxiously before the study hall while my hands shook wildly. I sat and observed every individual from my staff stroll into the study hall individually. Bumps framed in my throat as I attempted to swallow them into my agitating stomach. These were the picked understudies who would rely upon me, their editorial manager in-boss, for direction and help. The entirety of a unexpected, a penetrating ringing of the chime demonstrated that it was the ideal opportunity for me to start. I was the individual responsible for nineteen individual friends. I wasn?t sure what's in store while many inquiries dashed through my brain: What on the off chance that they don?t hear me out? Consider the possibility that I?m not experienced enough. Could I simply disregard this and return home? The primary day of class was the most nerve wracking furthermore, most terrifying day I have ever needed to understanding over the span of my fleeting paper profession. Planning a secondary school paper staff and making a paper at regular intervals is a great deal of fun, however then again, it includes a ton dissatisfaction. Much goes into delivering a secondary school paper, however most significant is the capacity to oversee and compose a gathering of individuals inside a dispensed measure of time. Tolerance is additionally urgent so as to comprehend and help other staff individuals. Notwithstanding, when it?s finished, the fulfillment is its own prize. Before understanding the whole paper creation process, there are a couple of key individuals whose obligations depend vigorously on it. The manager in-boss is the genuine ?top dog? or on the other hand ?head honcho.? As the editorial manager in-boss, it was my business to arrange and lead the class during each issue to deliver a paper. This distressing position required great authority aptitudes, relationship building abilities, furthermore, creation aptitudes since the other staff individuals relied upon me, the editorial manager in-boss, to direct them. The counselor is generally an instructor who doesn?t real run the class, yet exhorts the proofreader in-boss when required. Area editors have the obligation of spreading out each page in their segment. Some segment editors have colleagues to support them, yet most don?t on the grounds that they for the most part just have a few pages. Correspondents are the paste in this procedure. Everything depends on their story and the cutoff times they meet. Their principle obligation is to fulfill the time constraints. On the off chance that a columnist misses a cutoff time, or they are late, at that point the whole creation process gets kept down. For example, if a story isn't prepared, the area manager can?t design the page without a story; the picture takers can?t size the photos onto a page without a story on it; the guide can?t last that page until its finished with a picture and story on it; lastly, the editorial manager in-boss can?t take the paper to press without the pages finaled. Along these lines, everything that happens rotates around the journalist and his/her story. The second obligation of a correspondent is to compose a story sufficiently intriguing with the goal that the perusers will understand it. There is no reason for composing a story just to occupy room. On the off chance that that were the situation, at that point the endeavors (of the whole class) would be aimless. Picture takers likewise have numerous obligations. They are liable for taking and printing all the photos that will be set in the paper. The pictures must be noticeable and energizing to pull in the reader?s regard for the story. At times, they need to take twenty or thirty pictures of one athletic occasion to get that one great activity shot. So as to follow the strategies of paper creation, there are a couple of terms and paper language to comprehend. Sham sheets are the pieces of paper where area editors plan the pre-design of their pages. Each area proofreader is liable for around a few pages. To edit an image intends to cut an image or clasp workmanship in the proper extents to the picture box where it is to be set. Duplicate is the real content. All the animation like pictures or hand-drawn pictures are the clasp workmanship structures. Canals are the segments between the content that must stay vacant. At the point when a story or format is finaled, the journalist has experienced the procedure of

The sunny side of Joyce Carol Oates Essay Example For Students

The radiant side of Joyce Carol Oates Essay Joyce Carol Oates has consistently been attracted to the underside of the American creative mind. Sequential executioners, attackers and youth packs tail the pages of her books, and scenes of aggressive behavior at home, monetary hardship, dejection and fierceness are ordinary. The passionate atmosphere is extraordinary; the language frequently courageous; the vision destructive, even prophetically calamitous. Presently the essayist once called the Dark Lady of American Letters has ventured into daylight. The Perfectionist, which debuted at the McCarter Theater in Princeton, N.J. last October, was Joyce Carol Oatess first lighthearted comedy, and it came total with a cast of good-hearted characters, a bright rural setting and all the cheerful contraptions that go with the class. The entire venture was fairly far-fetched and perturbing, as though Jane Austen or Madame de Stael had out of nowhere transformed herself into Jean Kerrand no less astounding is the way Oates aced the fundamentals of Broadway light satire while never having seen one. There are, no doubt, a couple of grating thunderings en route just as a portion of the troublesome driving forces that underline the remainder of the writers workintimations of ailment, passing and medication reliance, an allegation of assault and at one point the risk of castrationbut the friendly comic soul she has called into soul figures out how to hold the foreboding shadows under control. We will compose a custom paper on The radiant side of Joyce Carol Oates explicitly for you for just $16.38 $13.9/page Request now So exactly what were the conditions that brought this most strange worka sort of screwball parody for the intellectual elite, the rural and tenuredinto being? Oates gives a multi-layered clarification, starting with closeness to the McCarter (she is presently the Roger S. Berlind Distinguished Professor in the Humanities at Princeton University) and her dear fellowship with Emily Mann, the auditoriums creative executive. It was constantly comprehended that I would attempt to compose something that may be reasonable for the McCarter. Emily has consistently been open to my work and I think in light of the fact that about her essence here I was urged to compose a sort of play I would not have in any case endeavored. I likewise love to learn new things, and for me The Perfectionist is an analysis in type. At long last, Oates offers what might be the best explanation of just for such a play: Life isnt all conflict and anguish. There truly are sentiments on the planet, she adventures. Individuals begin to look all starry eyed at. Consistently. While her scholarly notoriety lays safely on her composition fiction, Oates is turning into an obvious nearness in American theater. She is especially dynamic during the flow seasonwhich likewise discovers her on landscape more natural than the radiant domain of The Perfectionist. Dark, a singing dramatization of racial showdown, will open March 7 in New York at Womens Project and Productions. Oatess 1972 play Ontological Proof of My Existence, about a criminal who battles to have a little youngster while offering her available to be purchased to the most noteworthy bidder, was resuscitated by Chicagos Thunder Road Ensemble in November. I Stand Before You Naked, a montage play originally introduced at New Yorks American Place Theater in 1990, is entering its second year at the Theater Marie Stuart in Paris. Oates likewise as of late finished a lyrics for a drama dependent on her 1991 novella Black Water, an invented retelling of the Chappaquiddick episode, which is to get its reality debut in 1995 at the American Music Theater Festival of Philadelphia, just as a screenplay for Martin Scorsese. She is at present busy working on another full-length dramatization titled Bad Girls. The current season guarantees various exhibitions of her one-demonstration plays (I love short plays since they get promptly to the dramatization, she comments), which have demonstrated amazingly well known with school and little performance center gatherings as a result of their little throws and insignificant creation prerequisites. In any case, unexpectedly, of all her ongoing undertakings, it is the one set nearest to home that appears to have inspired the best inventive stretch. Oates concedes she would have truly liked to form. The Perfectionist as to a greater degree a fragile Restoration-type satire. Increasingly nostalgic and lighthearted comedy isn't my own taste. I graduated examinations in English, so I read Restoration dramatization, and I appreciate Congreve and Wycherly hugely. Be that as it may, those comedies are so difficult. The Perfectionist is set in a spot like Princeton, it has individuals in it who I know, and I didnt have the mercilessness to do that. .u8d040388acd5a5bbe7d62e28edddf0b0 , .u8d040388acd5a5bbe7d62e28edddf0b0 .postImageUrl , .u8d040388acd5a5bbe7d62e28edddf0b0 .focused content region { min-stature: 80px; position: relative; } .u8d040388acd5a5bbe7d62e28edddf0b0 , .u8d040388acd5a5bbe7d62e28edddf0b0:hover , .u8d040388acd5a5bbe7d62e28edddf0b0:visited , .u8d040388acd5a5bbe7d62e28edddf0b0:active { border:0!important; } .u8d040388acd5a5bbe7d62e28edddf0b0 .clearfix:after { content: ; show: table; clear: both; } .u8d040388acd5a5bbe7d62e28edddf0b0 { show: square; progress: foundation shading 250ms; webkit-change: foundation shading 250ms; width: 100%; haziness: 1; change: murkiness 250ms; webkit-change: obscurity 250ms; foundation shading: #95A5A6; } .u8d040388acd5a5bbe7d62e28edddf0b0:active , .u8d040388acd5a5bbe7d62e28edddf0b0:hover { mistiness: 1; progress: darkness 250ms; webkit-progress: haziness 250ms; foundation shading: #2C3E50; } .u8d040388acd5a5bbe7d62e28edddf0b0 .focused content region { width: 100%; position: relative ; } .u8d040388acd5a5bbe7d62e28edddf0b0 .ctaText { fringe base: 0 strong #fff; shading: #2980B9; text dimension: 16px; textual style weight: striking; edge: 0; cushioning: 0; content beautification: underline; } .u8d040388acd5a5bbe7d62e28edddf0b0 .postTitle { shading: #FFFFFF; text dimension: 16px; text style weight: 600; edge: 0; cushioning: 0; width: 100%; } .u8d040388acd5a5bbe7d62e28edddf0b0 .ctaButton { foundation shading: #7F8C8D!important; shading: #2980B9; outskirt: none; outskirt range: 3px; box-shadow: none; text dimension: 14px; textual style weight: intense; line-tallness: 26px; moz-fringe span: 3px; content adjust: focus; content adornment: none; content shadow: none; width: 80px; min-stature: 80px; foundation: url(https://artscolumbia.org/wp-content/modules/intelly-related-posts/resources/pictures/straightforward arrow.png)no-rehash; position: supreme; right: 0; top: 0; } .u8d040388acd5a5bbe7d62e28edddf0b0:hover .ctaButton { foundation shading: #34495E!important; } .u8d0 40388acd5a5bbe7d62e28edddf0b0 .focused content { show: table; stature: 80px; cushioning left: 18px; top: 0; } .u8d040388acd5a5bbe7d62e28edddf0b0-content { show: table-cell; edge: 0; cushioning: 0; cushioning right: 108px; position: relative; vertical-adjust: center; width: 100%; } .u8d040388acd5a5bbe7d62e28edddf0b0:after { content: ; show: square; clear: both; } READ: Evaluation of Live Theater: Nation EssayPart of the plays engage is that those on either side of the window ornament are a piece of a similar network, and the knowing chuckling of Princeton crowds, who rushed to distinguish the comedys natural sorts and catch its not so subtle references, genuinely set the performance center turning. It isn't a lot of a distortion to state that one left the McCarter, which sits on the edge of the universitys conveniently cut greensward, into the world one had abandoned. Oates says she has been keen on dramatization for as far back as she can recall, however the conditions of her early stages permitted her no immediate contact with the stage. I experienced childhood in a provincial network in upstate. New York and we were so distant from any sort of theater. Show wasnt educated however I read Eugene ONeil and Tennessee Williams when I was in secondary school. I started setting off to the theater when I set off for college in the late 1950s. I saw great plays on BroadwayRashomon and Tea and Sympathy and Archibald MacLeishs J.B., which was a significant encounter since it was a section show and a catastrophe. Oatess commencement into the performance center came in 1965 (It all started for such a long time agoits practically like another lifetime) when the executive Frank Corsaro, detecting something emotional in her distributed short stories, authorized her first play, The Sweet Enemy, for the Actors Studio Workshop. Other venue pieces followed every once in a while during the following two decades, the majority of them delivered Off Broadway. In 1990 she got a commission from Jon Jory and Actors Theater of Louisville, and just because turned into a functioning member in the dramatic procedure. I never had a lot of experience being in the theater and working at practices. Louisville kicked me off at that. From that point forward Ive been composing plays for all intents and purposes constantly. During the previous three years her work has been seen at New Yorks American Place Theater, Ensemble Studio Theater and the Contemporary American Play Festival, Massachusetts Williamstown Theater Festival, and Connecticuts Long Wharf Theater. Oates talks about composing plays and composing books as two completely separate controls. Its the distinction among swimming and running. Both are practices and can be fulfilling, yet they utilize totally various muscles. The test of the auditorium is to make the characters sufficiently striking to be alive in front of an audience and convey the heaviness of the activity. The composition account voice doesnt require this; youre recounting to a story. A play is likewise about forward force, and Oates compares its activities to that of a car. It needs to move. You can have a delightful Rolls Royce however on the off chance that something isn't right with its motor and it just sits in the garage, youd be in an ideal situation with another vehicle that moves. Obviously, content issues as well, yet Ive discovered that in the performance center pacing and speed are significant. In the event that individuals are nodding off, you come up short. She normally starts a play by envisioning a vacant stage or room where something will occur. It takes a drawn-out period of time. I sit and fantasize. The characters are kind of there and they begin moving around and talking. Dislike exposition narr

Managing Consumer Market

Question: Examine about the Managing Consumer Market. Answer: Presentation: The buyer advertise is affected by the administration items and market highlights. Keeping up of the unmistakable and elusive ascribes is important to make the purchasers intrigued towards the offered items or administrations. Judgment of the elusive qualities is essential before expending any help item. Vege Rama Shop is a prestigious café situated in Brisbane Australia. The clients who regularly visit the eatery favor the nourishment quality and atmosphere. Be that as it may, so as to investigate the impalpable variables of administration items, I visited the café as a secret customer. The involvement in the clients, nourishments, feel, and accommodation administrations will be related further: The significant aphorism of visiting the shop is to distinguish the conduct of the staffs, feel, and the quality parameter of other accommodation administrations.

In focusing on such issues, the servers are should have been prepared enough in managing the clients. Be that as it may, the other immaterial components hushed up great and along these lines, the experience was neither fulfilled nor disappointed. The café can be appraised 3 out of 6.

Designing A Freight Elevator For The Movement Of Goods Business Essay - Free Essay Example

There are many types of elevators like hydraulic elevator, Pneumatic vacuum elevator, mine shaft elevator etc. Freight elevator is an elevator which carries freight. A  freight elevator  is used to do just what its name implies: to elevate, or lift,  freight, or goods. It is built to carry goods rather than people. The smallest freight elevators are often called dumbwaiters. They are typically used in two-story buildings to move household goods such as laundry or dishes up and down. Though older versions were operated by pulling on a rope, modern dumbwaiters include a small electric motor. A heavy-duty freight elevator can hold a truck and can handle as much as 100,000 pounds using a dual rope system for support  [2] In this activity, we will first explore a possible model for the motion of a heavy-duty freight elevator used to raise and lower equipment and minerals in a mineshaft. We will evaluate the model for its strengths and weaknesses and then create a set of specifications to develop a model of our own. Analyzing a possible model: The possible model y = 2.5t3 15t2 represents the position of the elevator. Here y is in meters and is the vertical displacement. Here y = 0 when the elevator is at ground level. t is time in minutes and the starting time t = 0 minutes. The trip up and down the shaft, ignoring time spent at the foot of the shaft, is approximately six minutes and that the depth of the shaft is no more than 100 meters. I will use graphing software Graph 4.3 to visualize the motion of the elevator in the shaft which is shown below. displacement.png Graph : Displacement graph using the given model function I have calculated the position of the elevator at different time intervals which I have shown in the table below: Time t (minutes) Displacement (meters) 0 0.0 1 -12.5 2 -40.0 3 -67.5 4 -80.0 5 -62.5 Table : Displacement I have calculated the maximum and minimum displacement during the round trip of the elevator. The maximum / minimum d isplacement of the freight elevator during the round trip will be when the slope of the displacement function = 0 that is when velocity v = 0 Therefore = 7.5t2 30t = 0 ÃÆ' ¢Ãƒ ¢Ã¢â€š ¬Ã‚ ¡Ãƒ ¢Ã¢â€š ¬Ã¢â€ž ¢ t = 0 or 4 minutes. Therefore y (0) = 2.5(0)3 15(0)2 = 0 y(4) = 2.5(4)3 15(4)2 = -80 meters. Hence maximum displacement, ymax = 0 and minimum displacement, ymin = -80 meters. From the above table and graph we can observe the following facts. At time t = 0 and 6 minutes, the displacement is 0. This indicates that the elevator is at ground level at the start and the end of the round trip. Throughout the round trip, from t = 0 to 6 minutes, the displacement is negative. This indicates that the elevator is below the ground level which is evident from the graph also. The elevator descends to a maximum depth of 80 meters which is the ymin value at time t = 4 minutes. The time taken by the elevator to descend the maximum depth of 80 meters is 4 min utes whereas the time taken to ascend the same distance is 2 minutes. Since displacement y(t) = 2.5t3 15t2 meters We know that velocity is rate of change of displacement. Therefore Velocity = = y'(t) = 7.5t2 30t meters/minute Using graphing software I have graphed the velocity function which is shown below. velocity.png Graph : Velocity graph using the given model function I have calculated the velocity of the elevator at different time intervals which I have shown in the table below: Time t (minutes) Velocity v (meters/minute) 0 0.0 1 -22.5 2 -30.0 3 -22.5 4 0.0 5 37.5 6 90.0 Table : Velocity I have calculated the maximum and minimum velocity during the round trip of the elevator. The maximum / minimum velocity of the freight elevator during the round trip will be when the slope of the velocity function = 0 that is when acceleration a = 0 Therefore =15t 30 = 0 ÃÆ' ¢Ãƒ ¢Ã¢â€š ¬Ã‚ ¡Ãƒ ¢Ã¢â€š ¬Ã¢ „ ¢ t = 2 minutes. Therefore velocity is minimum at t = 2 minutes. v(2) = 7.5(2)2 30(2) = -30 meters / minute Since = 15. Therefore v is minimum at t = 2 minutes. v(2) = 7.5(2)2 30(2) = -30 meters/minute Therefore the minimum velocity of the elevator during the round trip is -30 meters/minute. From the above table and graph we can observe the following facts. When t = 0 and 4 minutes, the velocity is 0 meters/minute. It indicates that the elevator is at rest at the bottom of the shaft and at the ground level when it starts descending. During time interval 0 to 4 minutes the velocity is negative. This indicates that the elevator is moving downwards. During time interval 4 to 6 minutes, the velocity is positive. This indicates that the elevator is moving upwards. The minimum velocity is -30 meters/minute at time t = 2 minutes. We know that acceleration is rate of change of velocity. Therefore, Acceleration = = y(t) = 15t 30 meters/minute2 Using graphing software I have graphed the acceleration function which is shown below. accn.png Graph : Acceleration graph using the given model function I have calculated the acceleration of the elevator at different time intervals which I have shown in the table below: Time t (minutes) Acceleration (meters/minute2) 0 -30.0 1 -15.0 2 0.0 3 15.0 4 30.0 5 45.0 Table : Acceleration From the above table and graph we can observe the following facts. When t = 2 minutes, the acceleration is 0 whereas before t = 2 minutes it is negative and after t = 2 minutes it is positive. This indicates that the acceleration is changing its direction at time t = 2 minutes. During time interval t = 0 to 2 minutes, the acceleration is negative. This indicates that acceleration is in the downward direction. During time interval t = 2 to 6 minutes, the acceleration is positive. This indicates that acceleration is in the upward direction. I have graphed all the three displacement, velocity and acceleration functions together for comparison which is shown below. displ,vel.accn together.png Graph : Displacement, Velocity and Acceleration graphs using the given model function I have also combined all the values of displacement, velocity and acceleration at different time intervals for a comparative study as shown below. Time t (minutes) Displacement (meters) Velocity v (meters/minute) Acceleration a (meters/minute2) 0 0.0 0.0 -30.0 1 -12.5 -22.5 -15.0 2 -40.0 -30.0 0.0 3 -67.5 -22.5 15.0 4 -80.0 0.0 30.0 5 -62.5 37.5 45.0 6 0.0 90.0 60.0 Table : Displacement,velocity and acceleration. I have analyzed all the three displacement, velocity and acceleration together during the three time intervals as below. Between 0 to 2 minutes. During this time interval at t = 0 minutes, the displacement is 0 meters and a t time t = 2 minutes, the displacement is -40 meters. This indicates that the elevator is at ground level at the starting of the time interval and descends 40 meters by the end of this time interval which is also the half of the downward displacement of the elevator. During this time interval at t = 0 minutes, the velocity is 0 meters/minute and at time t = 2 minutes, the velocity is -30 meters/minute which is the minimum velocity of the elevator in the full trip. In this time interval the magnitude of the velocity is increasing. The negative values of velocity indicate that the elevator is moving downwards. During this time interval at t = 0 minutes, the acceleration is -30 meters / minute2 and at time t = 2 minutes, the acceleration is 0 meters / minute2. This indicates that the magnitude of the acceleration is decreasing in this time interval. In this time interval, the direction of both velocity and acceleration is same and downwards hence the acceleration helps the ele vator to speed up and the magnitude of the velocity increases. Between 2 to 4 minutes. During this time interval, at t = 4 minutes, the displacement is -80 meters. This indicates that the elevator is at the bottom of the round trip at the end of the time interval. Therefore during this interval of 2 to 4 minutes; the displacement is -40 meters. The elevator descends 40 meters during this time interval which is also the half of the downward displacement of the elevator. During this time interval at t = 2 minutes, the velocity is -30 meters/minute and at time t = 4 minutes, the velocity is 0 meters/minute. Therefore the elevator reaches its lowest point of the trip at time t = 4 minutes. In this time interval the magnitude of the velocity is decreasing. The negative values of velocity indicate that the elevator is moving downwards. During this time interval at t = 2 minutes, the acceleration is 0 meters / minute2 and at time t = 4 minutes, the acceleration is 30 meters/min ute2. This indicates that the magnitude of the acceleration is increasing in this time interval. The acceleration is positive during this time interval which indicates that the acceleration is upwards. In this time interval, both velocity and acceleration are in opposite direction. The acceleration is in the upward direction whereas the velocity is in downwards direction and the magnitude of the velocity is decreasing during this time interval. This indicates that, when the acceleration is in the opposite direction of the velocity, the velocity decreases. Between 4 to 6 minutes. During this time interval, at t = 6 minutes, the displacement is 0 meters. This indicates that the elevator is at the bottom of the round trip at the starting of the time interval and is at the ground level at the end of this time interval. Therefore during this interval of 4 to 6 minutes; the displacement is 80 meters. The elevator ascends 80 meters during this time interval which is the full ascen ds of the elevator. Therefore the elevator takes only 2 minutes to move from the lowest point of the trip to the ground level. During this time interval at t = 4 minutes, the velocity is 0 meters/minute and at time t = 6 minutes, the velocity is 90 meters/minute. The velocity is positive during this time interval and the elevator is moving upwards. Therefore the elevator reaches the ground level again at time t = 6 minutes and completes its trip. In this time interval the magnitude of the velocity is increasing. During this time interval at t = 4 minutes, the acceleration is 30 meters / minute2 and at time t = 6 minutes, the acceleration is 60 meters/minute2. This indicates that the magnitude of the acceleration is increasing in this time interval. The acceleration is positive during this time interval which indicates that the acceleration is upwards. In this time interval, both velocity and acceleration are in the same direction. Both the velocity and acceleration are in t he upward direction. The magnitude of the velocity is increasing during this time interval. This indicates that, when the both velocity and acceleration are in the same direction, the magnitude of the velocity increases. Conclusion: When both the velocity and accelerations are of the same sign that is they are in the same direction. The acceleration helps velocity and the magnitude of the velocity increases. When the velocity and the accelerations are of different signs that is they are in the opposite directions. The acceleration acts as retardation and decreases the magnitude of the velocity. Usefulness of the model function: The possible model function y = 2.5t3 15t2 models the complete round the trip motion by a single function. Problems in the model function: The main drawback of the given model function is that the elevator does not come to rest at the end of the trip when it returns back to the ground level. The velocity is 90 meters/minute at t = 6 minutes whereas the velocity should be 0 meters/minute. As per the model function, the elevator takes 4 minutes to descend to the bottom and only 2 minutes to ascend back to the ground level. This indicates that it takes double the time in descend compared to the time required to ascend. Since this is a vertical motion and gravitational force provides a gravitational acceleration downwards which always helps any object to move downwards and opposes any object to move upwards. Therefore the gravitational acceleration is helping the elevator while descending and opposing the elevator while ascending but the elevator takes half the time while ascending which means that the source of force required to take the elevator up has to be more powerful. This increases the cost of the equipment and operation. Using this model function the elevator can descend only up to a depth of 80 meters whereas the depth of the mineshaft is 100 meters. So the elevator can never reach the bottom of the mine shaft using this model function. Creating our own model: I tried to gather information for the speeds of freight elevators from the internet. The speeds of the heavy duty freight elevators manufactured by Hitachi Ltd., Japan are 30, 45 metres/minute.  [3] I have selected the maximum speed of freight elevator for my model as 45 meters/minute. Therefore the specification for redesigned freight elevator model is: The depth of the mine shaft the freight elevator has to descend is 100 metres. The maximum speed of the freight elevator is 45 metres/minute. The freight elevator takes equal time in descending and ascending from ground level to the depth of the mine shaft. The speed of the freight elevator is 0 meters/minute at the ground level, whether the freight elevator is starting from or reaching the ground, and at the bottom of the shaft. Looking at the above specifications, especially The freight elevator takes equal time during descending and ascending, which means that the displacement function graph is symmetri cal during ascend and descend. The elevator velocity is zero at the beginning, middle and at the end of the trip. The function which can suit the above requirements can be a sinusoidal cosine function. The cosine function starts from the maximum value 1 and ends at the maximum value 1. Also the cosine function is at its lowest value -1 at the middle of its cycle. Also the slope of the cosine function at these three points is zero and is symmetrical; hence it satisfies all the requirements of the model function. Therefore I will try a cosine function. The general cosine function is given by y(x) = A cos (Bx + C) + D. Here, A is the amplitude of the cosine function which is the difference between the peak and mean of the maximum and minimum y coordinates. B is given by B = where T is the time period and is the distance between the two successive maxima or minima. C is the horizontal translation of a normal cosine graph. This is negative when the graph is transl ated to the right and is positive when the graph is translated to the left. Its value is the horizontal shift of the point cosine (0) from the origin (0, 0). D is the vertical translation of the mean of the normal cosine function given by the mean of maxima and minima of y value. D is negative when the graph is translated downwards and is positive when the graph is translated upwards. Since I have taken the maximum depth of descend of the elevator to be 100 meters from the ground level. Therefore ymax = 0 and ymin = -100, therefore Amplitude, A= = 50 B = Horizontal translation, C = 0 Vertical translation, D = Substituting these values of A, B, C and D in the general equation of the cosine function I get the model displacement function as below: y(t) = = ÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦.(1) Therefore , Velocity v = = and, ÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦..(2) Acceleration a = ÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦(3) Now in the above model equations the only unknown is the time period or we can say the time required for the elevator one round trip. In our specification of the model function I have specified that the maximum magnitude of the velocity of the elevator will be 45 meters/minute. Now the velocity v can be maximum when sin = -1. Therefore maximum velocity, Vmax = = 45 meters/minute Therefore T = 6.98 minutes. Therefore our model displacement, velocity and acceleration functions will be Displacement, y(t) = meters Velocity v(t) = meters/minute Acceleration a(t) = meters/minute2 I have graphed the above model functions for visual check. cosine displ.bmp Graph : Remodeled displacement graph cosine velocity.bmp Graph : Remodeled velocity graph cosine accn.bmp Graph : Remodeled acceleration graph I have calculated the values of displacement, velocity and acceleration at different time intervals which is shown in the table below.

The elevator descends a depth of 100 meters at t = 3.49 minutes which is half of the time taken for round trip. Therefore the elevator descends to the bottom of the mine shaft. The displacement graph is symmetrical and the time required for descend and ascend is 3.49 minutes which means that the elevator takes equal time in descend as well as ascend. The remodeled function is single function, which take cares of all the drawbacks of the original model function. Hence I accept this remodeled function as my final model function. I will modify my remodel functions for a high speed passenger elevator. From the same web site of Hitachi limited, I gathered that the speed of passenger elevators is 180, 210 and 240 meters/minute. I will design a displacement, velocity and acceleration function for a passenger elevator with the following specification. The height the passenger elevator has to ascend is 240 meters and the maximum speed of the elevator is 240 meters/minute. Using this specification, I will remodel my function as below. Amplitude, A= = 120 B = Horizontal translation, C = Vertical translation, D = Substituting these values of A, B, C and D in the general equation of the cosine function I get the model displacement function as below: y(t) = = ÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦.(1) Therefore, Velocity v = = and, ÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚ ¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦..(2) Acceleration a = ÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦(3) Now in the above model equations the only unknown is the time period or we can say the time required for the elevator one round trip. In our specification of the model function I have specified that the maximum magnitude of the velocity of the elevator will be 240 meters/minute. Now the velocity v can be maximum when sin = 1. Therefore maximum velocity, Vmax = = 240 meters/minute Therefore T = 3.14 minutes. Therefore our model displacement, velocity and acceleration functions will be Displacement, y(t) = meters Velocity v(t) = 240 meters/minute Acceleration a(t) = mete rs/minute2 I have graphed the three functions for visual analysis as below. cosine displ paasenger.bmp Graph : Displacement graph for passenger elevator cosine velocity passenger.bmp Graph : Velocity graph for passenger elevator cosine acceleration passenger.bmp Graph : Acceleration graph for passenger elevator Form the above graphs we can see that with slight modifications of the model cosine function, it meets all the requirements of the high speed passenger elevator. So we can modify the cosine function so that the same can be adapted to any other similar application.
