Doctoral Dissertations 1896 - February 2014
Manufacturing technology has permitted an exponential growth in transistor count and density. However, making efficient use of the available transistors in the design has become exceedingly difficult. Standard design flow involves synthesis, verification, placement and routing followed by final tape out of the design. Due to the presence of various undesirable effects like capacitive crosstalk, supply noise, high temperatures, etc., verification/validation of the design has become a challenging problem. Therefore, having a good design convergence may not be possible within the target time, due to a need for a large number of design iterations.
Capacitive crosstalk is one of the …

Digital cameras and computers are widely available for students and teachers. However, they are mainly used for documentation: creating PPT presentations, handouts, posters, etc. STEM DIGITAL shows how digital image analysis can be applied to environmental (and other) research in STEM courses. Application to studies of air quality, water quality, arsenic contamination, climate change, diffusion, etc.

Measuring The Acceleration Of Falling Objects, John Pickle
Measuring The Acceleration Of Falling Objects, John Pickle
STEM Digital
Earth's gravity pulls all objects toward its center, and near the Earth's surface. Objects in free fall accelerate at 9.8 m/s2 vertically downward, provided air resistance is negligible. This value of acceleration is often referred to as "g". There are many ways to measure this rate of acceleration, and most require a timing device. Typically, stopwatches are the least expensive technology, so these are commonly available in high school science classrooms. With the recent addition of movie cameras on cell phones and digital cameras, another timing tool is available at moderate cost (free if the school policy …

Why are Polar Regions more affected by global warming than other parts of the globe? One reason (there are others) is that as sea ice melts and more open water appears, more energy is absorbed, and warming accelerates. This is a form of positive feedback and it makes the polar climate change faster than the climate in temperate areas. Increasing vegetation on land also has a similar positive feedback effect. This effect is a change in the albedo – the fraction of the incident sunlight that is reflected back to space.

Do Crayfish Change Color If Their Environment Changes? A Guided Inquiry Lab for 7th grade Life Science
Background: There is anecdotal evidence from bass fisherman that crayfish are able to change color depending on their surroundings. A (cursory) literature review of this phenomenon showed that no formal research has been done in this area. Students had an additional informal lesson about research funding (or lack thereof) because of this finding.
Students designed and conducted a controlled experiment to see the effect of changing environment color on crayfish color.
ADI was used to quantify a color change.
Human Variation In Skin Color And Race As A Social Construct, Jennifer Welborn
Human Variation In Skin Color And Race As A Social Construct, Jennifer Welborn
STEM Digital
This lesson is part of evolution unit which follows heredity and genetics
The lesson is interdisciplinary in nature in that I discuss the concept of race as a social construct and the idea that there are “black, white, red, yellow” skinned people is something that people developed. It is not based on biology. Race groupings are human-made groups.
Students first learn about mixing light and how to determine black and white from an ADI analysis. They learn that red and green = yellow, etc.
They then photograph each other’s forearms and analyze the images using ADI.
We then discuss skin …

•The water industry spends a lot of money and effort on removal of natural organic matter (NOM) from drinking waters •Problems with NOM (the more NOM the bigger problem) –NOM interferes with the ability of water treatment systems to remove substances that cause disease •Pathogenic organisms •Toxic chemicals –NOM reacts with chlorine‐based disinfectants forming carcinogenic organic byproducts

Bioretention: Evaluating Their Effectiveness For Improving Water Quality In New England Urban Environments, Mary Dehais
Bioretention: Evaluating Their Effectiveness For Improving Water Quality In New England Urban Environments, Mary Dehais
Masters Theses 1911 - February 2014
Nonpoint source (NPS) pollution is one of the leading causes of water quality problems in the United States. Bioretention has become one of the more frequently used stormwater management practices for addressing NPS pollution in urbanized watersheds in New England. Yet despite increased acceptance, bioretention is not widely practiced. This study explores and evaluates the efficacy of bioretention for protecting urban water quality.
This research found that numerous monitoring methods are used by researchers and industry experts to assess the effectiveness of stormwater best management practices (BMPs) and low impact development (LID) practices that include bioretention. The two most common …

On The Retrieval Of The Beam Transverse Wind Velocity Using Angles Of Arrival From Spatially Separated Light Sources, Shiril Tichkule
Masters Theses 1911 - February 2014
For optical propagation through the turbulent atmosphere, the angle of arrival (AOA) cross-correlation function obtained from two spatially separated light sources carries information regarding the transverse wind velocity averaged along the propagation path. Two methods for the retrieval of the beam transverse horizontal wind velocity, v_t, based on the estimation of the time delay to the peak and the slope at zero lag of the AOA cross-correlation function, are presented. Data collected over a two week long experimental campaign conducted at the Boulder Atmospheric Observatory (BAO) site near Erie, CO was analyzed. The RMS difference between 10 s estimates of …
