Karimi Engineering: Engineering is the creative application of science, mathematical methods, and empirical evidence to the innovation, design, construction, and maintenance of structures, machines, materials, devices, systems, processes, and organizations. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. Dr. Mohammad R. B. Karimi History: Engineering has existed since ancient times, when humans devised inventions such as the wedge, lever, wheel, and pulley, etc. wedge lever wheel pulley Dr. Mohammad R. B. Karimi The term engineering is derived from the word engineer, which itself dates back to the 14th century when an engineer (literally, one who builds or operates a siege engine) referred to "a constructor of military engines. A siege engine is a device that is designed to break or circumvent heavy castle doors, thick city walls, and other fortifications in siege warfare. Siege engine Dr. Mohammad R. B. Karimi The word "engine" itself is of even older origin, ultimately deriving from the Latin ingenium , meaning "innate quality, especially mental power, hence a clever invention." Later, as the design of civilian structures, such as bridges and buildings, matured as a technical discipline, the term civil engineering entered the lexicon as a way to distinguish between those specializing in the construction of such non-military projects and those involved in the discipline of military engineering.

In the Journal of Earthquake Engineering, a team of civil and environmental engineers studied the ground motion characteristics of 15 earthquakes that occurred around the world acceleration (feet per second), and the depth of the earthquake (in kilometers). One of the goals of the study was to estimate the inelastic spectra of any ground motion cycle. Com a. Identify the experimental units for this study. Choose the correct answer below. O A. The depth of the earthquake O B. The distance away from the epicenter O C. The peak ground acceleration O D. Earthquake sites b. Do the data for the 15 earthquakes represent a population or a sample? Explain. O A. The data represent a population since the data are a subset of the units of Interest O B. The data represent a sample since the data are a subset of the units of interest. O C. The data represent a sample since the data are all the units that are the subject of the study O D. The data represent a population since the data are all the unks that are the subject of the study. c. Define the variables measured and classify them as quantitative or qualitative. Choose the correct answer below. O A. The distance away from the epicenter. quantitative O B. The distance away from the epicenter, quantitative, the peak ground acceleration, quantitative; the depth of the earthquake, quantitative O C.

1.5 Ground motion of earthquakes. In the Journal of Earthquake Engineering (Nov. 2004), a team of civil and environmental engineers studied the ground motion characteristics of 15 earthquakes that occurred around the world. Three (of many) variables measured on each earthquake were the type of ground motion (short, long, or forward directive), earthquake magnitude (Richter scale) and peak ground acceleration (feet per second). One of the goals of the study was to estimate the inelastic spectra of any ground motion cycle. a. Identify the experimental units for this study. b. Do the data for the 15 earthquakes represent a population or a sample? Explain 1.13 CT scanning for lung cancer. A new type of screening for lung cancer, computed tomography (CT), has been developed. Medical physicists believe CT scans are more sensitive than regular X-rays in pinpointing small tumors. The H. Lee Moffitt Cancer Center at the University of South Florida is currently conducting a clinical trial of 50,000 smokers nationwide to compare the effectiveness of CT scans with X-rays for detecting lung cancer. (Todays Tomorrows, Fall 2002.) Each participating smoker is randomly assigned to one of two screening methods, CT or chest X-ray, and their progress tracked over time. In addition to the type of screening method used, the physicists recorded the age at which the scanning method first detects a tumor for each smoker. a. Identify the experimental units of the study. b. Identify the two variables measured for each experimental unit. c. Identify the type (quantitative or qualitative) of the variables measured. d. What is the inference that will ultimately be drawn from the clinical trial? 2.5 Beach erosional hotspots. Beaches that exhibit high erosion rates relative to the surrounding beach are defined as erosional hotspots. The U.S. Army Corps of Engineers conducted a study of beach hotspots using an online questionnaire. Information on six beach hotspots was collected. Some of the data are listed in the table. a. Identify each variable recorded as quantitative or qualitative. b. Form a pie chart for the beach condition of the six hotspots. c. Form a pie chart for the nearshore bar condition of the six hotspots. d. Comment on the reliability of using the pie charts to make inferences about all beach hotspots in the country.
