Physics - Assignment Example The universe comprises of millions of super clusters. These super clusters consist of hundreds of different sized galaxies. Of such a super cluster is our earth a part of. The super cluster consists of galaxies in the form of groups. The galaxy in which earth is situated is called Milky Way and is situated in a group called the local group which comprises of more than 30 galaxies (Caprara & Harris, 2003). The Milky Way is made up of a number of stars and constellations of stars, planets, rocks, sun, gaseous elements and other such similar things. Our earth is the part of a solar system which lies in the Milky Way galaxy. Our earth is the third planet from the sun. The Milky Way galaxy is extended in a number of directions and these extensions have been named as arms. The name of the arms has been given by the name of the constellation which can be observed in that particular direction. Orion spur is the name of one its minor arm in which our solar system is situated. It is placed at the far edge of the galaxy. The sun is approximately at a distance of 26,000 to 28,000 light years from the center of the Milky Way galaxy. 2. Electromagnetic Spectrum has been divided into different regions according to the difference in the values of the frequency and wavelength. Following are the types of waves comprising of the electromagnetic spectrum and their applications: 1.

Ajax Minerals and Perrier Essay Example | Topics and Well Written Essays - 1500 words

Ajax Minerals and Perrier - Essay Example Communications is highly necessary in regard to change management because it helps in creating mutual trust. The first way that communication to employees and the middle level management will help is in creating trust by the employees. This can be seen in the history of Ajax. In the past, Ajax failed to communicate to employees, and this led to the employees being suspicious any time the firm is about to make any changes. Communication is seen as a way to create trust because through good communication, it helps in making sure that the employees understand the need for change rather than leave the employees to speculate. The same kind of speculation has been the cause of resistance to change because the employees are extremely suspicious that any change process will affect the negatively. Involvement Involving the employee and the middle level managers is essential in helping to smooth out the process of change. When communication and involvement is used in concert, the best result will be achieved. Ajax is trying to involve the employees in the development of the solution and this will be necessary due to a number of reasons. The first reason is the fact that the involving the employees and the middle level managers will result in a change solution that will be accepted by the employees. Involvement will create minimal resistance from the employees. It will also be good in creating a solution that is most holistic in the way the firm deals with future problems. Will it succeed? Although Ajax has chosen to use this particularly valuable strategy to change management, there cannot be a guarantee that the strategy will succeed. This is because Ajax failed to use this strategy right from the beginning and there is a lot of suspicion in among the employees. Perrier case Perrier has a t least two sources of resistance. The first source of resistance is from the worker union CGT, which believes that Nestle does not have the right to cut off the number of workers in Perrier. The second source of resistance is definitely from the employees who feel that they need to protect their jobs. Nestle has tried to cut down employees in order to salvage the Perrier brand. When the employees could not allow the firm to cut the employees, the management placed the product of another brand in their cafeterias as a way to have the employees see the sense in trying to change. This method of trying to deal with the issue of change resistance did not help the firm to do away with resistance. If anything, this method of dealing with the issue made things between the management and the employees worse. Comparison There are a number of differences in the way the managers in both of these cases handled the case. Although the Perrier case was more complicated by the issue of the worker u nion that was

Intervention and Evaluation Essay Example | Topics and Well Written Essays - 500 words

Intervention and Evaluation - Essay Example It is imperative that intervention and evaluation measures must be taken to deal with these issues. Research data states that obesity has taken a form of epidemic in United States and there is a remarkable increase in the obese and overweight individuals since 1999- 2006, owing to increase BMI (Body Mass Index). If BMI is >40.0 an individual is said to be extremely obese and this accounts to 6% of the US population, on the other hand if the BMI of individual is >30.0, then he is under the category of obese and accounts for 34% of US population while individuals with BMI in the range of 25.0 – 29.0 are considered to be overweight and accounts for 33% of the US population. This segment of population are liable for chronic diseases related to heart viz. hypertension, type 2 diabetes, cancers and stroke (Recommended Community Strategies and Measurements to Prevent Obesity in the United States; The Community Foundation for Greater Atlanta). Identified Problems: Reasons paving the way for obesity followed by hypertension are formulated they encompass life styles, eating habits and diet, exercise, environmental factors including , lack of space to play and exercise and stress both at personal and professional levels. It is essential that states and communities must intervene to generate an atmosphere that sustain healthy eating and energetic living. Considering this as crucial issue, CDC instigated Common Community Measures for Obesity Prevention Project to formulate obesity prevention strategies and monitor its implementation for prevention of obesity followed by hypertension (Recommended Community Strategies and Measurements to Prevent Obesity in the United States; The Community Foundation for Greater Atlanta). Interventions: In order to create an awareness to combat with issues like obesity and hypertension, communities should come forward to enhance the availability of healthier food and beverages in public service venues including schools, parks,

7 Research Paper Example | Topics and Well Written Essays - 1500 words

7 - Research Paper Example In order to develop such a system, the software development team should make use of different design patterns because these patterns help them detect problems that arise during the development. It also provides an effective solution of problems (Martin, 2000). â€Å"In object oriented architectures, a design repeats the same structures over and over again. These repeating structures of design and architecture are known as design patterns† (Martin, 2000). Additionally, there are many design patterns that are used in different scenarios. In addition, each pattern is aimed at solving a specific problem (Hauck, 2014). The objective of this paper is to discuss the pattern that can be used for an automatic health monitoring system. In the scenario of an automatic health monitoring system the behavioral pattern is best suited because behavioral patterns are useful for supporting communication between different objects. In software engineering, behavioral design patterns are typical design patterns, which are required for identifying common communication patterns and connecting different objects. In this manner behavioral patterns are helpful in increasing flexibility in carrying out any sort of communication between objects. In fact, this pattern offers much greater flexibility than other patterns because this pattern allows software developers to decouple objects from each other. Due to this coupling and decoupling facilities, they can be easily configured to make dynamic algorithms and methods (Schatten, 2013; Morandi, et al., 2013). In the scenario of an automatic health monitoring system there are different objects, which have various relationships and can demonstrate different results in response to different inputs. The pattern that we will use for an automatic health monitoring system is known as behavioral pattern. The working of this pattern is discussed

Construction Technology and Innovation Essay Example | Topics and Well Written Essays - 1000 words - 2

Construction Technology and Innovation - Essay Example More of this advancement has been geared too towards the conservation of the environment (FLICHY 2007, pg19). There are various building forms in the UK which are mostly dependent on their respective uses. The various designs of the building forms are done taking into account their occupancy and the use to which they are subjected (FLICHY 2007, pg37). Such forms include; residential buildings mostly permanent houses and/or low-rise buildings constructed with a view to provide housing; Institutional buildings constructed for various institutional purposes (these could include larger engineering buildings, high rise buildings); and Industrial buildings and commercial buildings. The building construction methods should conform to the various standard and codes provided for their regulation. This should undergo careful planning so as to avoid possible wastes and to ensure that they are secure and safe. In addition, the materials used for construction should be carefully evaluated to avoid constructing bulky houses with poor architectural outlooks (AKINTOYE, GOULDING & ZAWDIE 2012, pg36). Most of these materials should be considered to relation to their costs, structural soundness and their availability. As a general rule in most civil and building constructions, the availability of materials would to a large extent dictate the construction materials to be utilized for the constructions. In the UK, the various construction methods available have been utilized with a view of reducing the time for construction and costs. In addition, the construction methods help in improving the quality of buildings produced i.e. relating to the types of finishes required. The in situ construction of buildings has been used for decades and provided the most conventional building procedures (AKINTOYE, GOULDING & ZAWDIE 2012, pg56). Construction is done on

Methods of Risk Analysis and Management

Methods of Risk Analysis and Management RISK ANALYSIS METHODS Risk management can be divided into four steps: risk identification, risk assessment, risk control, and risk records. In recent years, studies have mostly focused on the risk assessment. Risk assessment is to analyze and measure the size of risks in order to provide information to risk control. Four steps are included in the risk assessment. According to the results of risk identification and build an appropriate mathematical model. through expert surveys, historical records, extrapolation, etc. to obtain the necessary, basic information or data available, and then choose the appropriate mathematical methods to quantify the information. Choose proper models and analysis methods to deal with the data and adjust the models according to the specific circumstances. Determine the size of risks according to certain criteria. In the risk assessment extrapolation, subjective estimation, probability distribution analysis and other methods are used to obtain some basic data or information. Further data analysis often use following basic theory and methods: layer analysis method, mode cangue logical analysis method, Monte Carlo simulation, the gray system theory, artificial neural network method, fault tree analysis, Bayesian theory, an influence diagram method and Markov process theory. We can divide the methods into qualitative analysis and Quantitative Analysis. Qualitative analysis: 1. Fault Tree Analysis Fault Tree Analysis Fault Tree Analysis (Fault Tree Analysis, FTA) can be used for qualitative analysis of risk and can also be used for quantitative analysis. It is mainly used for large-scale complicated system reliability and safety analysis. It is also an effective method to Unification reliability and safety analysis, through hardware, software, environment, human factors.FTA is drawing a variety of possibilities of failure in system failure analysis, from whole to part, according to the tree structure. Fault tree analysis using tree form, the system The failure of components and composition of the fault system are connected. We are always using fault tree in qualitative or quantitative risk analysis. The difference in them is that the quantitative fault tree is good in structure and it requires use of the same rigorous logic as the formal fault tree, but qualitative fault tree is not. Fault tree analysis system is based on the target which event is not hoped to happen (called the top event), one level down from the top event analysis of the direct cause of their own events (call low event), according to the logical relationship between the upper and lower case, the analysis results are obtained. 2. Event Tree Analysis Event tree analysis (event tree analysis, ETA) also known as decision tree analysis, is another important method of risk analysis. It is the events of a given system, the analysis of the events may cause a series of results, and thus evaluates the possibility of the system. Event tree is given an initial event all possible ways and means of development, every aspect of the event tree events (except the top incidents) are the implementation of certain functions of measures to prevent accidents, and all have binary outcomes (success or failure). While the event tree illustrates the various incidents causes of the accident sequence group. Through various intermediate steps in the accident sequence group can organize the complexity of the relationship between the initial incident and the probability of systemic risk reduction measurement, and identify the accident sequence group. So we can calculate the probability of each of the key sequence of events occurred. 3. Cause-Consequence Analysis Cause and consequence analysis is a combination of fault tree analysis and event tree analysis. It uses the cause analysis (fault tree analysis) and the result analysis (event tree analysis), CCA aims to identify the chain of events leading to unexpected consequences, according to the probability of occurrence of different events from CCA diagram to calculate the probability of different results, then the risk level of the system can be determined. 4. Preliminary Risk Analysis Preliminary risk analysis or hazard analysis is a qualitative technique which involves a disciplined analysis of the event sequences which could transform a potential hazard into an accident. In this technique, the possible undesirable events are identified first and then analyzed separately. 2 For each undesirable events or hazards, possible improvements, or preventive measures are then formulated. This method provides a basis for determining hazard categories and which analysis methods are most suitable. It is proved valuable in the working surrounding to which activities lacking safety measures can be readily identified. 5. Hazard and Operability studies (HAZOP) The HAZOP technique was origined in the early 1970s by Imperial Chemical Industries Ltd. HAZOP is firstly defined as the application of a formal systematic critical examination of the process and engineering intentions of new or existing facilities to assess the hazard potential that arise from deviation in design specifications and the consequential effects on the facilities as a whole.2 This technique is usually performed using a set of guidewords: NO/NOT, MORE OR/LESS OF, AS WELL AS, PART OF REVERSE, AND OTHER THAN. These guidewords, a scenario that may result in a hazard or an operational problem is identified. Consider the possible flow problems in a process line, the guide word MORE OF will correspond to high flow rate, while that for LESS THAN, low flow rate. The consequences of the hazard and measures to reduce the frequency with which the hazard will occur are then discussed. This technique is accepted widely in the process industries. It is mostly regarded as an effective tool for plant safety and operability improvements. Detailed procedures on how to perform the technique are available in some relevant literatures. Quantitative Analysis: Fault Tree Analysis It is explained in the Qualitative analysis. Expected value Expected value is the possible outcome times the probability of its occurrence. An expected value shows the percentage of yielding a target in a business. Sensitivity analysis In sensitivity analysis shows how the outcome changes in response of a particular variable change. One can get result from optimistic, most likely and pessimistic values. An example of inputs for sensitivity analysis is the material and labor cost that can be much fluctuated.
