Non Linear Behaviour And Chaos - 1277 Words

ABSTRACT In this report non-linear behaviour and chaos have been explored through Duffing Equation computationally. Key features of the chaos theory such as attractors, Poincarà ¨ sections and phase-space diagrams have been analysed and discussed. The programing language of choice for this experiment was Fortran 90, which has been written explicitly for the purposes of acquiring a chaotic system and solving the Duffing equation. Introduction The Duffing Oscillator named by the German electrical engineer Georg Duffing is a non-linear, second-order differential equation, periodically forced and includes a damping term proportional to particle’s velocity. The equation can show different types of oscillations such as a limit cycles and chaos. Given its characteristics Duffing oscillators are often used to produce similar behaviours in nature. The equation in this experiment has been studied through the dynamics of a particle under a potential field, driven by an applied periodical force. The equation of motion for the particle in this system is (1) Where constant A gives the strength of a non-linear term, B gives the strength of the linear term, C controls the size of damping, D controls the periodic driving force, and ω is the driving frequency. The changes in the environment caused by the periodic force are sufficient to lead a chaotic behaviour, as is the case with Duffing Oscillators. Most of the systems in universe have a non-linear nature. Although a majority ofShow MoreRelatedKurt Lewin and complexity theories: back to the future?7984 Words   |  32 Pagesseen as outmoded and irrelevant to the needs of modem organizations. It might be expected that this tendency would increase as academics and practitioners draw on the work of complexity theorists to portray organizations as complex, dynamic, non-linear self-organizing systems.

In order to examine these conflicting views, the article begins by reviewingRead MoreIs Destiny a Matter of Chance or Choice?1268 Words   |  6 Pagesthe behaviour of the system.

Improve Inventory Management To Support Maintenance...

BACKGROUND Material management is one of the main components in the management of all types of companies. Material management plays an important role in supporting the companys performance, which relates to customer satisfaction, cost of production and financial performance.

However, should the quantity of inventory it should not be too large so that capital tied up in inventory and costs. Meanwhile the inventory is not too big and not too small anyway because can slow down the production process. Failure materials inventory control default will cause a failure in obtaining profit.

PROBLEM FORMULATION Abuhilal (2006) stated that the ultimate goal of inventory management is giving satisfaction to the customers need at the lowest price. There are two types of customer, internal customer and external customer. In company’s operation, PJB only has internal customers of inventory management, there is maintenance division.

According to the CEO decree, now PJB using three classification stock keeping unit to maintain more than 30.000 item of materials. The first classification is the impact of material to power plant operation, then the lead time of delivery and the last classification is about usage value every year (price multiplied by demand value). The stock keeping unit is classified and managed into three criteria. Then, by applying those classification the inventory manager develop policy to keep inventory in optimum level.

Hypocrisy in to Kill a Mockingbird Free Essays

Hypocrisy is a huge theme of Maycomb’s society and community spirit. For example, racism plays a huge role. In the Tom Robinson trial, he is accused of raping Bob Ewell’s daughter, Mayella. We will write a custom essay sample on Hypocrisy in to Kill a Mockingbird or any similar topic only for you Order Now But the real story is that Bob Ewell is abusive to his daughter and accused tom Robinson because he’s black. Since the social community is mostly tipped on the scale of discrimination, there are excuses made for whites. This leads into another following example. In the minds of the â€Å"good Christians† blacks are made to be slaves and do everything a white man says. Atticus is completely against this and tells Bob off. In retaliation, Bob Ewell makes it certain Tom Robinson is guilty. In the end Tom is purposed guilty even though the evidence clearly shows he’s not. The Maycomb community thinks they’re doing what’s right for the town and titles themselves â€Å"The Good Christians. † A few people, like Atticus, know they are wrong and knows they only persecuted Tom Robinson by the color of his skin. Another example of hypocrisy referring to racism would be with Mrs. Gates. Mrs. Gates is completely against Hitler thinking what he did was absolutely horrible about what he did to the Jews. But then again in her own community people are persecuting blacks the same way. Another example similar to this is Mrs. Merriweather talks about saving the poor Mruans from Africa but thinks black people in her community are a disgrace. Scout and Jem throughout the book later discover the hypocrisy in the adult world. Some examples would be, Aunt Alexandria’s view on the Cunningham’s, Lula not wanting her kids to go into a black church etc: Jem noticed the hypocrisy in the Lula situation was Lula complaining about all white people being prejudice against them but in her hate for whites and their prejudice she is also being racist and prejudice. Scout and Jem then noticed someone being mad at a certain race for doing the exact same thing they were doing. How to cite Hypocrisy in to Kill a Mockingbird, Essay examples
