As the name suggests, cylindrical coordinates are 3-dimensional and involve polar coordinates. It combines the 3-dimensional Cartesian coordinate system (x, y, z) with the polar coordinate system (r, θ). The “r” stands for radius while the “θ” stands for theta (the angle usually represented in radians). The x and y are replaced with the polar coordinate system while z stays the same.The coordinates are shown in this manner: (r, θ, z). Graphing cylindrical coordinates is easy as long as you know

In the appendix section, we display all betas for respondent 1 and 5. The results vary considerably depending on the beta and the respondent. This pattern and behavior of the model suggest that 100,000 iterations could not be sufficient to have a robust model. Figure 3 shows the beta distribution of the subset iterations (after 10,001 iterations) for beta 1, beta 2, beta 3, and beta 4. As noticed, these beta values have a low dispersion, unimodal and cryptokurtosys; even though, not all beta values

1- What was experimentally wrong with the Ghostbusters ESP study (video link) at the end of your chapter one slideshow, and how could it be improved to meet scientific standards? In the Ghostbusters ESP study, the Dr. Peter Venkman was studying the effects of positive punishment on ESP ability using the man subject instead of the effects of negative reinforcement on ESP ability as he stated, which was experimentally wrong. This was demonstrated when the man subject guessed the right card and Dr

1. The higher drop heights for black walnut on asphalt will less run ins with predators while foraging 2. The lower drop heights for English walnut on asphalt will make foraging more energy efficient 3. A height of 6 m will break English walnut on asphalt and lessen foraging time 4. A height of 9 m will break a black walnut on asphalt and a English walnut on soil with the least energy expenditure A. I would expect individuals to ignore false alarm calls when there is a competitive feeding situation

Several studies have examined the differences in ERP components under immediate and delayed feedback conditions in healthy adults, particularly the ERN and FRN. While both ERP components occur during the processing of errors, there are some notable differences. The ERN occurs in close temporal distance to motor initiation during responses that result in an error, and peaks at roughly 80-100 ms (Gehring, Goss, Coles, Meyer, & Donchin, 1993; Miltner, Braun, & Coles, 1997; Holroyd & Coles, 2002). In

The data is from the 2014 American Community survey conducted by the US Census Bureau. The data is measure on a county level and accounts for all members of the county. The variables of focus are the population of the county and foreign born population to calculate the foreign born percentage of each county. Other variables of interest are the working age population and the number of people unemployed to calculate the unemployment rate. Additionally, there is data on mean income per family in the

In the data analysis section, the researcher’s stated that descriptive statics were used to analyze the questions that asked about the demographic characteristics of the participant. This is an appropriate statistic to use for this type of information. Both inferential and descriptive statistics were used to analyze the close ended questions in the survey, such as yes/ no responses and Likert- scale questions. The Friedman rank test was used to analyze a Likert- scale question measuring the difference’s

Based on Miller and Lovler (2015), pilot testing is a procedure that is used to test a small, intended audience to see if there are any potential issues that could arise once the original test is administered. The data is analyzed and the test is revised based on the findings. There are several benefits of preforming a pilot test. One of the main reasons as suggested earlier, is that it can warn administrators about any failures prior to the main study or research. In addition, a pilot test can point

Student Name: Noor Alharbi Faculty: Dr. Gopal Sankaran, HEA 520 (81) Public Health Epidemiology Fall 2015 11-14-2015 Critique of peer-reviewed published journal articles Critique Two Study Design The study design in a case study is supposed to be epidemiological, whereby test subjects are studied under similar circumstances for a specified period of time. Therefore, in order to acquire accurate results, controlled variables must be administered in equal and measured proportions

Comparisons... Comparisons have become an inevitable and integrated with life and work. Even though myself & most of us don’t like comparisons since every individual is unique and should never be compared for what they are with others and comparison always make sense when it’s made self, within, which can only be the real truth. Even in Agile, it’s advised not to compare two teams with their velocity, since every team features and work are different. Saying that, certain situations, act and benchmark
