Measuring Heart Beats (ECG)

The heart rate of an individual has been defined as the number of times a heart beats every minute (Edlin and Golanty, 2016). When a heart beats, it pushes a volume of blood into the circulatory system. At some points in the circulatory system where the blood flows near the skin surface, one can feel blood flowing as a result of heartbeat. It is at these points where heart rate is measured. Usually, the heart rate of a person is measured at the carotid artery in the neck, radial artery located in the wrist just below the thumb, or ...

Introduction

Wind engineering is a significant component in civil engineering. This is because winds can have devastating effects on different manmade and natural structures. Windstorms produce large amounts of damage every year (Holmes, 2007). Weather conditions such as thunderstorms generate local winds, whereas hurricanes and typhoons may generate very strong winds. Designing of buildings and structure takes into account the dead load of the structure plus the imposed load. However, in including a factor of safety for the structures the engineers have to factor in the wind load.

A transformer is an electrical piece of equipment used in electrical circuits to alter the voltage of the electricity flowing in a circuit by either increasing the voltage (stepping up) or decreasing the voltage (stepping down) (Pansini, 1999). Alternatively, they may be described as static machines which transform power from one circuit to another while maintaining the electrical frequency constant. Transformers are, therefore, very important devices in the distribution of electricity. There are two main reasons why transformers are important in the process of electricity distribution: “Stepping up” and “stepping-down.” First, once produced at the power station, the electric ...
