Observations of Joints Present in the Lawton Clay Member of the Vashon Stade, Exposed at a Coastal Bluff in Discovery Park, Seattle, Washington

The southwest-facing coastal bluff present at Discovery Park, Seattle, Washington, displays distinctive joints throughout the exposed Lawton Clay Member. Exhibiting a characteristic local stratigraphy of permeable advance outwash over the impermeable proglacial lacustrine clay, this bluff is located in an area of Seattle at high risk from landslides. This project addressed the relationship between the joints observed at this coastal bluff and the coherency of the bluff as a whole, through remote sensing and field measurements. Aerial drone photography taken of the bluff was processed through a photogrammetry software to produce a 3-dimensional Structure from Motion model, allowing for a digital manipulation and broad examination of the bluff not possible by foot. Stereonet plots produced from these measurements provided insight into patterns of varying joint strike along a horizontal transect of the observed bluff face. Taken together, these two visualizations provided a better picture of the possible chicken-and-egg interaction of the joints and bluff topography; they demonstrated the likelihood that the joint formation at the bluff was most likely to be primarily influenced by the local topography of the bluff over other sources of possible tensional stress in the immediate area.

Use of the Maple System in Math Tuition at Universities

The following article explores the application of educational technologies at a University level and their contribution in enhancing the educational effectiveness. It discusses the capabilities of computer algebra systems, such as Maple. It is integrated in the math tuition of the Technical University (TU) in Varna and is used by its students during laboratory exercises.

Using Physical Quantities in Applied Mathematical Problems with Maple

The present article discusses units of measure and their base units, work environments built in the Units package of the computer algebra system Maple. An analysis is drawn of the tools of the application in connection with the use of physical quantities and their features. Maple’s main commands are arranged in groups depending on the function. Some applied mathematical problems are given as examples making use of derivative, integral and differential equations.
