Essays on Computations

Abstract

Computational complexity was introduced and developed by Hartmanis and Stearns in order to provide methods in measuring the degree of complexity or difficulty of computational problems or functions as well as to measure the efficiency of algorithms. It was developed through understanding of numerous complex problems and analysis of the issues within these problems. The history of the subject of computational history started with the theoretical computational model or a machine developed by Alan Turing in during the 1930s. In his paper, he convinced the scientific community that developing an effective algorithm is possible. The Turing machine paved way ...

Abstract

Statistics involves the collection, analysis, interpretation, and presentation of data. The analysis, interpretation, and presentation techniques use the excel program. The excel features make it easy for statisticians to conduct researches as the program provides a convenient way to enter data into the program and run to determine the actual outcome of research. In particular, the excel program is applied in the statistical research in different forms. For example, it can be applied to a database which stores data to allow easy retrieval for references if need be. In addition, excel allows the calculation of simple and complex statistical ...

Introduction

Capital budget analysis refers to the process through which the way a firm invests capital in projects that result in cash flows over a period of more than one year. The analysis is built on the assumption that the firm depends on the specific project or projects under analysis in order to operate and consequently, it becomes important to test whether or not the projects being considered would be viable. Notably, capital budget analysis comes with several assumptions including the estimations of cash flows from the specific project as well as the assumption on the state of the economy ...

Introduction

The oil and gas industry in North America is currently experiencing challenges and transition stage. The increasing need for the environment-friendly and sustainable forms of energy is affecting the industry negatively as more governments and companies are encouraged to use energy with no or low carbon emission. More companies are now developing solar and wind energy and create vehicles that can rely on electricity rather than oil. Such growing trend in the energy sector resulted to lower demand of oil and gas particularly in the North America. Many oil and gas producing countries and companies ...

Introduction

Capital structure refers to a company’s alignment of the long-term and short-term debts, common equity and the preferred equity. The term also include the analysis of how the company decides on how to allocate the cash flow into various components including a portion that is allocated to meet the financing needs of the debt capital and the other portion that is allocated to the shareholders as part of the dividend. Capital structure is a subset of the financial structure. Financial structure refers to the relative proportion of the various sources of finances that are used in the business ...

Summary of Thinking, fast, and slow by Daniel Kahneman

George Mason University Summary of Thinking, fast, and slow by Daniel Kahneman Introduction The author, Daniel Kahneman, hopes that the readers would benefit from the reading of his book, which is about biases of intuition. According to the author, it can be a tough choice between what we believe and what we want. Friends and colleagues help us in making and evaluating choices. The thinking process is one conscious thought leading to another. The mental work creates impressions and intuitions silently in our minds. We allow our beliefs, feelings and preferences to feel confident about our decision, even if ...

Question No. 1 - Statement of the Incremental Cash Flows over 8-Year Period

Based on the given information and data, the following statement is extracted to reflect incremental cash flows for each year accompanied by a table showing calculation of depreciation expense using straight line method:

Question No. 2 - Payback Period (PBP) and Net Present Value (NPV)

Payback Period (PBP) The period within which the initial investment in project could be recovered represents the Payback Period (PBP). The criteria of making investment decision in case of this capital budgeting technique is that any project that has a Payback Period (PBP) beyond the one “required” by the business is ignored. In the same manner, only those projects are accepted that help an organization recover ...

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 ...
