5.2.2.2 Interpretation of Regression Model The above equation can be written as D ∝ P^0.058/(V^(-0.117) 〖D_b〗^(-0.133) ) By observing the above equation we can say that the LAZ Depth is directly proportional to the Laser Power and inversely proportional to the Scan Velocity and Beam diameter. The observations of the model can be summarized as below: As Laser Power increases the LAZ Depth of workpiece surface will also increase. This is because the heat input to the workpiece is increasing…

In this stasis map paper there is four parts of an argument that will be discussed.This argument process was developed by Aristotle and Hermogenes, in ancient Greece.The four parts are conjecture, definition, quality and policy. Conjecture is the cause and the effect of an argument.Definition is the “What is the nature of the problem/issue?What exactly is the problem/issue?What kind of a problem/issue is it?To what larger class of things or events does it belong?

The I-35W Mississippi bridge was an eight lane, three span deck truss bridge which carried the interstate highway 35 across the Mississippi river. It was located in the biggest city of Minnesota, Minneapolis. It carried around 140,000 vehicles per day, making it the second busiest bridge in Minnesota. Construction repair and renew work was scheduled to be carried on the bridge again in 2020 or so. However, on August 1st, 2007, it collapsed all of a sudden, thereby killing 13 people and injuring…

Modern day building construction has progressed over centuries with the incorporation of new construction methods. This includes the various building types, designs of structures, and the application of building and fire codes. The effect of building construction has changed how firefighting operations are conducted, the hazards associated with building types, and the effects of fire on each type. The potential for building collapse remains a safety issue for firefighters and situation awareness…

In his book, "Crude Oil: The Violent Twilight of Oil", Peter Maass discusses about the world's unremitting pursuit and dependence on oil. He contends that oil dependency has led to conflicts and war between and within countries. Specifically, the oil-producing countries, mostly the developing nations, do not gain from the oil revenue since their governments are marred with corruption and poor governance so that the leaders monopolize the income. Consequently, these countries have remained in…

In simplest terms, the main reason for this injustice is environmental racism. Environmental racism can be described as environmental health discrimination based on race, mostly low income communities of color (Shelton & Miller, 2016). Environmental discrimination can take the form of placing…

studies, pregnant animals (rats, mice, rabbits, and sometimes amphibians) are killed just prior to delivery and the fetuses are examined for any sign of toxic effects by the test substance.” (Product Development and Drug Testing).
