Bouncing Ball Model: Use of Zero-Crossing Detection

Executive Summary
In the system of a bouncing ball there are many factors which influence how the ball bounces. The 5 main components which affect how high the ball will bounce include the initial position of the ball, the initial velocity of the ball, the elasticity of the ball, the gravity of the selected area, and also the temperature of the material in which the ball was made from. These 5 major components of the basic system determine how high the ball bounces and how much energy was lost in the process of bouncing as well as allowing us to determine the relationship between these components and how each of these affects the overall system as a whole. However by changing these components of the system, it will dramatically change the overall results.

In the system of a bouncing ball there already at secondary school level, illustrates Newton’s laws of motion and concepts of gravitational energy and kinetic energy with examples of objects dropped or thrown vertically and contains investigative activities about falling objects, the physics and mathematics. The fives main components which affect how high the ball will bounce they are initial position, the initial velocity, the elasticity, the gravity and the temperature of the material in which the ball was made from. These five major components of the basic system determine how high the ball bounces and how much energy was lost in the process of bouncing as well as allowing us to determine the relationship between these components and how each of these affects the overall system as a whole.

‘’a Flexible Firm Model Optimizes the Use of Human Resources’’

...‘’A flexible firm model optimizes the use of human resources’’ Kalleberg, 2001 * Social and economic changes in the past century have underscored the need for organizations to have greater employment flexibility. * Industrial countries and manufacturing sectors emphasize in human resource management that organizations can adapt any changes in technology, in labour markets, price competition, in capital markets internationally and nationally. * A great deal of attention has been paid in recent years to human resources management practices that are designed to provide employees with skills, information, decision-making responsibility and incentives to improve business performance. These new practises are replacing unions and collective groups of people. * Flexibility adapts the size, composition, responsiveness, and the cost of labour in order to achieve organization’s goals. * Explanation of this: 1) Organizations often hire people for shorter period with specific assignments and this is cheaper than employing permanent staff that maybe sometimes are not fully utilised 2)The size of organization and that of labour force varies from organization to organization 3)High supply of workers willing to work casually- High unemployment and more and more people are educated and the working system cannot absorb them into jobs (Bennett, 1994) * David Guest (1987) in advocating de-centralisation emphasised the role it plays in increasing flexibility......

Forecasting Model in Use

...BU3315 Unit 4 Research Paper 2 Forecasting Model in Use For this research paper I used a study done by Sprint for forecasting usage costs and computer capacity required for their network and cell phone towers. The use of data related to transactions collected from computing devices in their facilities was used to calculate a forecast of usage at peak hours. This study was done in the early stages of Sprint becoming a cell phone company and it is still used today to help upgrade and maintain their network. This helped Sprint determine a forecast of data usage on customer cell phones so they could determine the type and amount of equipment needed to get ample coverage and network bandwidth to provide their cell phone service to the customers. The methods they used were 5 variables used in their forecasting model; 1. First span of time comprises usage in seconds, minutes, hours, days, months and years. 2. Computing device comprises at least one of a server, telecommunications switch and computer 3. Data collection of computing software processes, computer programs used, business logic model, and software usage (apps) 4. Software usage at server farms 5. Threshold percentage representing actual customer airtime usage By doing this Sprint was able to determine the demand that customers would be putting on their networks and the bandwidth being used. The first inclination was to build a massive network of coverage all across America to stake claim......

What Use Is the Westminster Model of British Government?

...What use is the Westminster Model of British Government? The Westminster model for centuries has always been the face of British politics. “Traditionally British political scientists tended to believe that the Westminster model provided democratic and effective government” and “was well suited to gradual and evolutionary change, capable of adapting where appropriate but conserving traditions and conventions that had proven themselves to be effective over a long period” (McAulla, 2006, p. 14). However, within recent decades the debate of whether the Westminster model is of use to the British government was created. This can largely be a result to the United Kingdom joining the European Union and aspects of devolution. To answer the question of what use is the Westminster model of British government, the Westminster model must firstly be understood. Thus, I will first explain the core features of the Westminster model and then assess its use of British government. The Westminster model is a unique one and parliamentary sovereignty exemplifies this. Under the Westminster system, power resides exclusively in a single national authority; parliament with no entrenched and autonomous powers being vested in any other body (Norton, 2004, p. 324). As such, no national body can question the legitimacy of its decisions, however, theoretically, the monarch holds the power to dissolve parliament. Other than that, parliament can pass any bill it wishes in theory and can remove any......

...can be found in daily usage of internet and cell phones, computers and or laptops and microwaves. In an economically stable country, many of these technologies are commonly used on a daily basis. Other examples involve science as chemistry by means of cooking using measurements and combinations of ingredients. Science is seen in everyday life using energy, by the use of light, gas functioning utilities, etc. Medically, science is found with the advancement in pharmaceutical drugs, antibiotics and other related medicinal innovations. Even in our daily commute, science is part of our everyday encounter weather by car, bicycle or on foot which is the usage of motion as well as energy. 2. By what criteria might you determine whether a question might be answered using the scientific method? Through conducting an experience one might be able to determine whether a question might be answered using the scientific method. 3. Identify a current piece of legislation relating to science or technology (perhaps an environmental science or energy bill). How did your representatives in Congress vote on this issue? Did they use scientific knowledge or receive wisdom to arrive at their decision? As of recently, drones have been a technology that is talked about in several state and country legislations. Some say that drones are not needed; others see them as an aid for the 21st century. Californian senators, Barbara Boxer1 and Dianne Feinstein2, have voted that drones not be used in......

The Crossing

...The crossing The relationship between the father and the son The protagonist is an unnamed man somewhere between 30-50 years old, and located in a small depression, because text says; "He had not been happy in a while." The protagonist is divorced or separated from his wife: "... He had not wanted here back, had not wanted much of anything really" (line.15) It would seem that the protagonist himself is to blame for the divorce, as he nurtures a desire that things should work again, both in relation to his ex-wife, but perhaps most in relation to his son. The father is very caring and loving to his son, and you quickly sympathize with him as the reader "... when the boy came running into the living room he threw him over his shoulder, careful not to hit his head on the corner of the TV…" (Page 2. line16-17) The protagonist wants to pass some of the good childhood memories that he had with his own father. They also used to take the same trip, and the main character repeats many of the same principles and rituals with his own son. Since the reader does not have access to the boy's thoughts and feelings, just as we have in the father. The author paints a picture of him with descriptions and through his father's thoughts about him. Most of all, we get a picture of a small frail boy. This narrative technique enables the reader to quickly sympathize for the boy and especially his father, who tried to get him safely through their journey in the wilderness: "He looked at......

Use the Chameleon as a Model to Manage Change.

...organizations can be likened to animals living in a jungle where only the strongest can survive. The business or organisation in this case represents a system which is open to and interacts with its environments. Open systems have four specific characteristic which make appropriate for these business .The first is the interchange between the system and its environment, secondly an open system is made up of a range of variables and a complex network of interrelationships. Thirdly for control the open system use anticipatory management which involves the anticipation of errors and problems before they come (Laszlo,1996). Fourthly, open systems are flexible and dynamic in nature for they move away from prescribed and rigid standards This paper seeks to explain how the chameleon model strategy as proposed by biologist Ludwig von Bertalanffy in the 1940s, and furthered by Ross Ashby (1956) is, relevant and appropriate in the survival of organizations in an ever-changing environment. The model was developed following the logic of the system theory. A system view considers an organisation as a set of interacting functions that acquire inputs from the environment ,process them ,and then release the outputs back to the external environment (Daft,2001). The system‘s identity and nature is directly and indirectly influenced by its environment which helps determine its orientation. Whilst the chameleon’s characteristics can easily be perceived to be negative when compared to human......

...Crossing Old traditions never die. Over thousands of years have fathers and sons taking on fishing trips. It is something very classic traditions to do. It creates a closer relationship between father and son. The shot story ”Crossing” is written by Mark Slouka in 2009. The title is crossing. The obvious reason why the title is crossing is because the father and his son have to cross a river. But usually is there always something deeper behind. Crossing can also mean to cross something in your life. You have to cross through hard times in your life. After I have read the story do I think the title crossing, can relate to the death. You are crossing from the earth and into the heaven. The short story is about a father and his son that try to cross a river. The father takes his own son to exactly the same place that he went with his own father back in the days. In the beginning of this story are we introduced with the father and his very difficult period of his life. He always reminds himself about his own childhood. When he was about 17 years old, took his father and him on a trip. He had a bad relationship with his father. His father often speaks hard to him and use swearword when he talk to his son. I think because he had a bad relationship to his own father and he has felt it first-hand. In the text: ““ It didn’t matter. Whatever it was had passed. He and his son would be friends. Nothing mattered more.” That shows us that he only want to be a better......

...companions, they are civilized members of the household, and they are easy to care for. In the first place, people enjoy the companionship of cats. Many cats are affectionate. They will snuggle up and ask to be petted, or scratched under the chin. Who can resist a purring cat? If they're not feeling affectionate, cats are generally quite playful. They love to chase balls and feathers, or just about anything dangling from a string. They especially enjoy playing when their owners are participating in the game. Contrary to popular opinion, cats can be trained. Using rewards and punishments, just like with a dog, a cat can be trained to avoid unwanted behavior or perform tricks. Cats will even fetch! In the second place, cats are civilized members of the household. Unlike dogs, cats do not bark or make other loud noises. Most cats don't even meow very often. They generally lead a quiet existence. Cats also don't often have "accidents." Mother cats train their kittens to use the litter box, and most cats will use it without fail from that time on. Even stray cats usually understand the concept when shown the box and will use it regularly. Cats do have claws, and owners must make provision for this. A tall scratching post in a favorite cat area of the house will often keep the cat content to leave the furniture alone. As a last resort, of course, cats can be declawed. Lastly, one of the most attractive features of cats as housepets is their ease of care. Cats do not have......

Foot Ball Coaching

...but by and large, the positions do not. The Goalkeeper The goalkeeper is the only player allowed to use his hands and that can only occur within the confines of the penalty area. There are never more that two goalkeepers on the field at any time — one on each team. The goalkeeper’s uniform is different from the rest of his team’s to make it obvious which player may use his hands. The jersey, often with long sleeves, is colored to clash with the others. And since the 1970s, goalkeepers have worn gloves to both protect their hands and enhance their grip on the ball. Some of the best goalkeepers in the world are Gianluigi Buffon of Italy and Iker Casillas of Spain. The Defenders A defender’s primary duty is to win back the ball from the opposition and prevent them from scoring. Teams play with anywhere from three to five at the back and each member of the defense tends to have a different, yet equally important duty. The defenders stationed in the center of the back line (known as central defenders or center backs) tend to be some of the taller and stronger members of the team since they so frequently have to win the ball in the air. They go forward very little, except on set pieces, and hold a position of great responsibility. The defenders on the flanks (known as wingbacks in five-player defenses, or fullbacks) are usually smaller, quicker, and better on the ball. Their job is to shut down attacks coming down the sides, but they are also frequently a key......

Advertisement Detection

...a viewer he might want to record the movie or a particular program and would prefer a break free one i.e. without any advertisements. There have been set top boxes or software that detect and discard the commercials on the broadcast TV signal. Study in the field of the advertisement identification is segmented into various manners. It can be dependent on the audio or video information or an amalgamation of both. There are some works by A. G. Hauptmann and M. J. Witbrock (2006) that use the verbatim data achieved from the text streams, or the optical character recognition or speech identification for segmentation. In work proposed by L.-Y. Duan et al (2007) it has been given that using usual features of advertisement blocks like frames and silence amid commercials to identify cuts and categorize commercials dependent on OCR. In this work there have been two varied use cases for the commercial detection 1. Identify broadcast of recognized commercials with large precision something like the use of fingerprinting 2. Identify earlier not known commercials. Next segmentation is to differentiate amid the methodologies on online instantaneous or offline processing. A few approaches require investigating the entire video to identify the maximums and to calculate attributes with progressive requirements, while the rest depend on the fly identification of the advertisements. Also there are variations amidst the advertisement identification in the compressed and uncompressed......

...border, novel method is used to serve this purpose, this method is generally used for detection of logo video frames this is important to indicate the beginning and finish of the advertisement at the borders detected by audio. Investigations display that merging audio and visual traces is an effective way to detect advertisements. INTRODUCTION Recognition based algorithms play important role in detecting advertisements in the personal recordings of a program on TV. Many algorithms are used to detect the commercials. For many consumers facilities such as recording of television program have proved highly convenient, this can be achieved through combination of technologies such as set top box and digital media storage, this facility is getting highly popular because of decrease in costs (Sadlier et al, 2002). In this framework, audio visual investigation gears that aid the user to accomplish the huge amount of data play important role for such recording devices (Lienhart, Kuhmnch, & Effelsberg, 1996). There are many other benefits of this system also can be seen such as detection of TV advertisements and some other investigation tools. For example, if the perspective of the end user is taken into the account, it will be highly beneficial for the end user if advertisements are not recorded while the program is being recorded. There are two types of prevailing advertisement detection methods (Harris, & Stephens, 2008). CHARACTERISTICS OF COMMERCIAL There are......
