An earthquake is any seismic event that causes seismic waves. These can be caused by human activity or natural causes. For example, fracking often causes earthquakes which are human caused. Earthquakes often shake or displace the ground or surface of the earth near the epicenter and if the displaced earth is under the ocean, it will usually cause a tsunami. Most earthquakes are caused by geological faults but they can also be caused by landslides, mine blasting, and volcanic activity. Earthquakes are measured by overserving seismometers that are set up across the globe in strategic places for ...

The Napoleonic Wars in the 18th and 19th century not only produced one of the greatest military geniuses of all but also revolutionized warfare. Napoleon is regarded as a great strategist who made use of the existing military strategies. During this period, two great thinkers, Carl von Clausewitz and Antoine Henri Jomini, recorded and interpreted the military strategies being employed by Napoleon. Clausewitz and Jomini are probably the greatest military thinkers to emerge from the Napoleonic era. After the Napoleonic wars ended, Clausewitz and Jomini sought to explain the emerging warfare by writing new doctrines and truth about war. ...

Cross-cultural management points on the essence of considering the differences in practices, cultures, and preferences desired by the consumers, for example in a social or a market set up. According to Hofstede perspective, there are independent categories that help identify the differences in cultural practices. Relatively, the perspective only adopts the notion of using the U.S as the ideal cultural practice when comparing with other regions. Notably, the idiosyncracies are unique to U.S management alone. They include focusing on manager instead of the worker, personal stress and stressing on the market process.
The Hofstede perspective lacks diversity since it ...

Automated Fingerprint Identification System (AFIS) refers to a computerized system used to store fingerprint images. Typically, investigators feed new print images into AFIS to identify the best matches. Accordingly, the identification process allows investigators to narrow their search parameters. Usually, AFIS technicians perform the final analyses of retrieved images to maintain accuracy. Prior to the computerization of such systems, the process of comparing fingerprint images was tedious and sometimes inaccurate. The development of AFIS, however, allowed technicians to perform comparisons within minutes and achieve a relatively higher accuracy of image identification.

Introduction

A wind turbine is a device that uses the kinetic energy derived from wind to create mechanical energy. This simply means the wind’s force pushes the blade into motion. Different wind turbines have different ways of extracting wind energy like most machines. Aerodynamics, on the other hand, simply refers to the flow of air about a body. This makes aerodynamics to be a critical aspect of wind turbines as this flow of air about the turbines is what determines its power output. This paper focuses on the aerodynamic behavior of wind turbines (Hansen 21).

Question 1:

Valve sticktion refers to the condition where the valve’s stem is resistant to small changes in its input. The main cause of this is when the static friction of the valve at rest is greater than the dynamic friction resulting from the force acting on the valve. However, even under sticktion, once enough force has been applied the valve stem will move easily. This makes the movement of the valve to be unpredictable and inconsistent (Michel, n.d).

Question 2:

Sticktion contributes to poor loop performance since if there is sticktion and an input is present the valve may overshoot leading ...
