Analyzing and Graphing Motion on Video
Kinematics, the study of motion, is critical to understanding physics. For that reason it is among the first topics covered in introductory physics classes and it acts as a foundation for much of the rest of the course. Graphs are an important element in the study of kinematics. Interpreting the large amounts of data displayed on graphs is critical to making sense of the field. Because features...
متن کاملGraphing Kendall's tau
Correlation is an important and widely used concept, and it is usually taught through word explanation or graphic description accompaniedwith a numericmeasure if such ameasure exists. In this note, we explore graphing one of the commonly used correlation measures, Kendall’s , in such a way that we display how Kendall’s is calculated and see how Kendall’s is influenced by data features. © 2006 E...
متن کاملTerrestrial Laser Scanning for Plot-Scale Forest Measurement
Plot-scale measurements have been the foundation for forest surveys and reporting for over 200 years. Through recent integration with airborne and satellite remote sensing, manual measurements of vegetation structure at the plot scale are now the basis for landscape, continental and international mapping of our forest resources. The use of terrestrial laser scanning (TLS) for plot-scale measure...
متن کاملEvaluation of a Smartphone App for Forest Sample Plot Measurements
We evaluated a smartphone app (TRESTIMATM) for forest sample plot measurements. The app interprets imagery collected from the sample plots using the camera in the smartphone and then estimates forest inventory attributes, including species-specific basal areas (G) as well as the diameter (DgM) and height (HgM) of basal area median trees. The estimates from the smartphone app were compared to fo...
