My town of choice was Lisbon, Portugal. The longitude is -9.139337 and the latitude is 38.722252. It is the capital and the largest city in Portugal, with a population of 552,700. It is the 11th most populous urban area in the European Union. It is continental Europe's westernmost capital city and the only one along the Atlantic coast. It is one of the oldest cities in the world, and is recognized as a global city because of its importance in finance, commerce, media, entertainment, arts, international trade, education and tourism. I chose Lisbon because I traveled there one ...

The results of the inventory test indicate that my learning style is visual. This means that I opt for visual and graphical representations such as the use of bars, charts, and graphs, compared to either reading or listening to materials. For this reason, I am able to relate to content that is visually presented as I am able to remember and understand such information relatively more easily, compared to other learning styles such as aural or auditory or verbal styles. For this reason, it is recommended that I should opt for the use of visual aids, flashcards, graphs, and ...

Response: “But then they danced down the streets like dingledodies and I shambled after as I've been doing all my life after people who interest me, because the only people for me are the mad ones, the ones who are mad to live, mad to talk, mad to be saved, desirous of everything at the same time, the ones who never yawn or say a commonplace thing but burn, burn like fabulous ...

Chapter 3: Methodology

3.0 Introduction The theory of purchasing power parity is essential for the study of international trade since it argues that there exist a relationship between prices of products and exchange rates. This theory provides a framework for assessing long-term changes in the exchange rates. It states that similar goods and services in various countries should have the same cost in the long-run (Frankel 153). Essentially, the PPP theory is based on the assertion that the exchange rates tend to adjust themselves in such a way that there no opportunity costs for buying particular goods or services in a particular ...

Abstract

Over thirty years after its identification, HIV and AIDS remains a somewhat elusive virus, particularly when it comes to its history as a human infectious agent, and resourcing a complete epidemiology of the disease. Part of the problem is that so many antiretroviral drugs have come out and have either been used or prescribed incorrectly. In addition, the virus, like many other reverse RNA transcriptase viruses, has a very high aptitude in terms of developing resistance to drugs at a very rapid rate. What further complicates matters is how quickly it has spread. It will probably never truly be ...

The Solow Model

For long, the concept of economic change has been interesting economists. The reasons why some of the countries are poor while others are rich or even the understanding of why some nations grow faster than others has constantly disturbed the understanding of most economists. The theory of economic growth has been put upfront in explaining the growth indices of different nations. In its place, the theory of economic growth aims at explaining whether poor countries can grow faster than their rich counterparts, catch up with them and close their income gaps, that is converge. Elaborated by Trevor Swan and ...

Business Statistics

Statistics is the methodology developed by scientists and mathematicians for interpretation and drawing conclusions from collected data (Isotalo, 2012). The main activities involved in statistics are collecting, processing, analyzing, interpreting, and presenting of data. Everything under these fields or anything remotely related to the fields, and the planning preceding these activities all belong to the domain of activities. Statistics is very broad and is not applied to science and mathematics alone but vast fields including business.

Conflict between Capitalists and Landlord

There exist diminishing returns to scale in the agricultural production due to the limited amount of land. When the world population increases, then the production of the agricultural production increases while more people are hired in the agricultural production. The surplus is distributed to the landowners (as rent), to the workers (as the wage), and the capital owners (as profit). Under the condition of diminishing returns, the agricultural production cannot increase the surplus to increase the profits, the wages, and the rent. The rent is fixed for the limited amount of land; therefore, the capital owners and the workers ...

Introduction

The kinetic characteristics are important for the design of chemical engineering processes. They allow assessing the time required for the reaction and choosing the temperature range suitable for the reaction. The reaction path is observed by measurments the transmittance of the Crystal Violet solution that reacts with sodium hydroxide. The concentration, and the color of the solution changes with the reaction flow, and this is measured by the spectrophotometer.

The data are plotted as concentration - time and logarithm concentration time, and the reaction rate is:

Rate = [Crystal Violet] [Sodium Hydroxide]. Using the excess concentration of one of the reagents, the reaction rate with respect to the other reagent is found from logarithmic plot (Rahul & Chakrabarti ...

1. The Sine and Cosine graphs are 'complementary', which means that the expression sin2 x + cos2 x = 1 is realized. Therefore, when sin (x) = 1, in that point cos(x) = 0, and vice versa. The same situation is observed when the functions take -1 and 0 values. Therefore, if Sine and Cosine are plotted on the same graphs, they look the same, but as if Cosine function is shifted by pi/2 comparing to Sine. Since Tangent function is obtained as sin x / cos x, then the point x = it should not reach the x-points pi/2, 3pi/2, etc. The ...

Production efficiency refers to the production of goods at the lowest possible cost. On the other hand, production inefficiency refers to the production of goods at a higher cost than the existing costs known. Economists view an economy as productive efficient if it can use its minimum or limited resources in the production of the maximum amount of outputs for the given economy. An economy that is production inefficient is one that does not use its given resources to produce the maximum number of units. Graphs as very essential for economists in illustrating such concepts. An example of the ...

Question one

The country with the highest industry margin is the USA, which gets 60.6% from every litter of oil, followed by Canada and Japan, which acquire 53.5% and 47.9% per litter respectively. On the other hand, the countries with the lowest industry margin are Italy and the UK which in every litter, they get 29.0% and 29.7% respectively (OPEC statistics Data/Graphs). The high prices of oil in the UK, Germany, and Italy, will most likely lower consumers’ demand for the product since as the price per litter goes up, the quantity of oil demanded decreases. In addition, individuals’ investment in ...

Traditional Chinese painting is reffered to as “guo hua” Chinese painting is closely linked to the means with which it is produced. The most used materials were ink and glue, that had to be rubbed to the necessary consistency with adding some water. The paint was applied with a brush made of animals’ hair and a stick of bamboo. As a basis of the painting there was used a sheet of silk or paper with spongy surface, due to which paintings were not subjected to correction. Thereby, the artist had to carry out his work with a high level ...

Statistics can be defined as the science of learning from data, measuring, controlling, as well as communicating uncertainty. Statistics therefore offers the best navigation essential to control the course of societal and scientific advances (Beri, 2005). Statistical methods and thinking are applied by statisticians to a variety of social, scientific and business models in subjects such as economics, marketing, astronomy, education among others. The techniques used in interpreting statistical data are widely used in making social, political, economic and political decisions. Qualitative data in statistics is used to describe variables who have a non-numeric format. These types of variables ...

The start of my writing carrier proved to be an uphill task for me. As a result, I learnt the hard way when I first ventured into the idea of writing. When I started thinking about the way, my writing has changed from the start of the semester to the present moment, my thoughts wandered through many different things. I feel that I have improved my writing and I can now write better to the audience instead of writing for myself. Furthermore, my belief is that I have acquired the ability of controlling my sources instead of allowing the ...

The Problem

For this case study, we focus on an application of regression analysis in engineering. In this case study, we use data to build a model for predicting average electrical output, y. In this case study, we use data from a Combined Cycle Power Plant to build a model for average electrical output, y. We examine the residuals, the deviations between the predicted and the actual electrical output levels, to detect an independent variable omitted from the regression model.

Management Accounting

Step 1: Question 1: The total variable cost for the company comprises of manufacturing costs and sales and administrative cost. Accounting both, the total variable costs for the firm was calculated at $10 per unit

Question 2:

The total production costs for any organization is bifurcated as fixed costs and variable costs. Important to note, while the variable costs and output carry a direct and proportional relationship, fixed cost is not related to output level and remains constant throughout. In other words, while the variable costs increase in proportion to the increase in output level, fixed cost does not change and ...

Abstract

The aim of this experiment was to determine the relationship between the Young’s Modulus and the deflection of a beam. Since different materials have different values of Young’s Modulus, the students selected three different materials for the experiment. In this case, the materials used include timber, aluminium, and steel. All the materials were identical in terms of the dimensions such as width and length. The each beam of the three materials was subjected to some magnitude of force at the centre and deflection measured. Data concerning the magnitude of load and the corresponding defection were then gathered ...

Abstract

In this case, we illustrate the application of multiple regression in economics. We gather data on the unemployment rate (dependent variable) and three independent variables; GDP per capita, maximum weekly unemployment benefit and population estimate for 2015. The data is collected from 39 different states. Regression analysis results show that there is a positive association between the unemployment rate and GDP per capita and population estimate. The relationship between unemployment rate and maximum weekly benefits is inverse. The evaluation of the reliability of the first-order model shows that it has a small coefficient of determination. The first-order model is ...

Global warming refers to a system of climate changes that are responsible for causing an increase in the average temperature of the lower atmosphere which affects the average thermal gradient of the Earth. Global warming may have a great variation among the causes, but it is most principally associated with human interference, specifically with the release of excessive amounts of greenhouse gases”. The most popular and common definition of the global warming is “Warming caused by human activity.” (Weather Street) There are several gases in the Earth’s atmosphere which are responsible for the increase in the global temperature ...

BERNOULLI’S EXPERIMENT

ABSTRACT Two fluid properties, the Bernoulli principle and the Venturi effect, were examined and analyzed in this experiment. A venturi meter was used to measure the fluid flow rate, velocity, and pressure of water (the fluid being examined). The results showed that the fluid pressure decreases as the fluid traveled through a smaller cross sectional area. The minimum fluid pressure (in effect, maximum fluid velocity) was observed in the smallest cross sectional area at position D (diameter 16 mm). The decrease in fluid pressure was compensated by an increase in the fluid velocity. With these two measured phenomena, both ...

It was a beautiful sunlit morning, and our class was confined in a classroom taking a Math test our teacher gave us. There was nothing in that test that I didn't know: there were some fractions to solve, some proportions to do, and some graphs to draw. I felt quite confident, because I had studied for the test and cramming everything before the test actually did me good, as the blank with the test questions did not look so daunting to me. I quickly skimmed through all the tasks to determine the value of work I was to do, ...

Introduction

Scientific method is described as a field of practices that is used to examine various phenomena, obtain knowledge and even incorporate or correct previous knowledge. The scientific method is established on evidence that is measurable and empirical as well and which is subjected to some standard of reasoning. Scientific method can also be defined as a method that follows a systematic process of observation, experimentation and formulation as well (Hesse-Biber and Johnson, 2015).

Importance of Mathematics in our Daily Life

Introduction Many students had disliked mathematics or math and had given up on appreciating its use. Some do so since they see Math as a hard and intimidating subject, while some do not simply see the point of studying it. However, many have discovered and acknowledged that Math is indeed an important part of our lives. They had recognized that Math is an indispensable tool and that many encounters or transactions are highly dependent on it such as in banking and economics. Likewise, the technology in today’s society is the fruit of algorithms, several mathematical computations, and mathematical ...

Introduction

Bend (flexure) testing is often done in springs as well in brittle materials whose behaviors of failure are linear like concrete, wood, plastic, glass and ceramics. Bend testing is suitable for evaluating the strength of brittle materials where the results of tensile tests aren’t easy to interpret due to the breaking of specimens around the gripping (Schoffstall, Charles, and Robert 234). In bend testing experiment, smooth rectangular specimens without notches are recommended under three or four point bend arrangements. Figure I below illustrates three point and four point bend arrangements respectively. Figure 1. Bend testing of a smooth ...

Summary of the Paper

‘The Great Escape: Intergenerational Mobility in the US since 1994’ by Nathaniel G. Hilger presents the authors work on how he develops a new method to estimate intergenerational mobility (IM) in educational attainment on US census data spanning 1940-2000. Using the new method, the author measures directly for children still living with parents at ages 26-29 and indirectly for other children using imputation procedure that is validated in multiple datasets thereby spanning the full sample period (Hilger, 1). The method is dubbed ‘new’ because it is the first to estimate educational IM on birth cohorts spanning 1911-1971 in a ...

[Economics] As everyone knows, oil is considered to be a raw material. Though there are some unknown oil stocks, oil as well as other minerals is an exhaustive type of resource. Moreover, no matter what scientists say, or give any predictions, in the nearest future we will run out of this mineral. That is one of the reasons why we can observe the price gradually raising now. But to be honest, by 2020 this factor will not influence significantly the price of oil. The explanation to this is because the vast majority of world’s oil stocks have already ...
