Task 2  

Download the lab4_plot_data.txt file from Moodle. The file contains the x (first row) and y (second row) coordinates.  

Write MATLAB m-file that performs the following: 

1. Read the data points from lab4_plot_data.txt 2. Plot y against x using red circle markers. 3. On the same figure, plot the function sin(x) as a black continuous line. Remember to include a legend and place it in the bottom left corner. 

Do not forget to label your plots. Use either the fgetl() or the importdata() functions to import your data.  

Task 3 It turns out that some values in lab4_plot_data.txt vary too much from the sin(x) curve and should be removed as they are considered noisy (invalid). You are tasked with the following: 

a) Remove the noisy data using the following rules. Do not set the invalid data points to 0, [] or NaN! Use logical statements in addition to true (1) and false (0) values to complete the task. a. An absolute difference of 0.4 or greater between the data point and the sin(x) value is deemed noisy b. The 11th, 59th and 88th data points are also deemed noisy. b) Plot the valid (noiseless) data points as blue circles on the same figure produced in Task 2. Therefore, the red circles now represent the noisy data while the blue circles represent the valid data. Remember to include a legend.

Write a 4 page essay on Adult Communication.

In the United Kingdom if one to ask for a rubber, the individual would receive an erasure made of rubber. Across the Atlantic in the United States of America, if one were to ask for a rubber, the individual would receive a rubber condom. Exchange of the same information has produced different results. Hence for a better understanding of what communication stands for it needs to be defined as the process of managing messages with the intention of creating meaning.

Having understood the more realistic meaning of communication, communication competence has more to it then just the ability to exchange information clearly with another individual using a common system of symbols, signs or behaviour. There is an element of a goal in communication, which is sharing of meaning and this has a connection with the thoughts and feelings of another individual. The acceptance that communication is goal driven also suggests that communication is strategic. This understanding of communication provides us with the means for abetter understanding of communication competence, as now it suggests that communication competence is not just communicating with accuracy, clarity, comprehensibility, coherence, expertise, effectiveness and appropriately. Communication competence is better expressed as the situational ability to set attainable and appropriate goals for achievement and to maximise the achievement of these goals through employing strategies of the knowledge of self, others, context, and the elements of communication theory to bring about adaptive communication performances. As communication competence involves competence there is a need for measurement. Communication competence can be measured through the determination of whether the goals of interaction have been achieved and the extent to which they have been achieved. This in my view is the meaning of communication competence (Rueben, 1976).

Write 4 page essay on the topic Is Qatar Economy Favorable for Capital Investment.

Oil and Gas are potential products and the two products cover half of the country’s Gross Domestic Product (GDP). The country earns substantial revenues from exporting oil and gas to many countries of the world. The country is progressing for many years due to increasing prices of oil and gas in the international market. Oil and gas are the tools that have provided high per capita income in the country. The country has a low rate of unemployment that indicates the strong economic position of the country. The country has nearly 25 billion barrels of oil and around 25 trillion cubic meters gas reserves that could be utilized by the country for more than 57 years in future. Qatar economy is represented as a stable economy due to its cautious macroeconomic management and natural resources (Qatar Economy Profile 2014, 2014).

The country has practiced tight fiscal policy in the period of 2002-2008 when revenues were mainly generated from oil and gas products. The new projects of Qatar are indicating high growth in the economy such as Qatar’s metro system, light rail system and changing the infrastructure of the country in near future. The country has inflation so to control it the country adopts tight monetary and fiscal policy. The country has an advantage of a low unemployment rate that indicates that tight economic policies are preferred by the country to reduce inflation and retain its economic growth. It is expected that the budget of 2014-2015 will be surplus of 24 billion dollars because of high prices of oil. The monetary and fiscal management is practiced by the government on account of the country’s current economic position (Nafi, 2014).

Oil and gas cover approximately half of the GDP of the economy. The energy resources that contribute over 50 percent of the total GDP are potential resources of the economy that will p0rovid much revenue in future.&nbsp.
