Student Grade Book Exporter
This was a new project I created for my Computer Science Practicum III capstone course (COMP 495) in the Summer 2013 semester. The project conception came from the following processes: 1. I copied all assignments from the course grade book and manually put them into my Google Task list. 2. I created an Excel spreadsheet that computed my personal statistics for the course and point goals needed to achieve a specific grade level. I directed my team in using the following final approach: a Chrome extension to parse the grade book web page, insert a task for each assignment into the user’s Google Task list and create a course file on Google Drive. The course file is read from an Android device and provides the statistical and achievement calculations. The final application was deployed to the Chrome and Play stores as an invite-only closed beta. The process reduced approximately twenty minutes of work down to around thirty seconds. When made public, this system will assistant other Franklin University students by: having tasks created for every assignment in a course and by having detailed information about their courses on an Android device.https://fuse.franklin.edu/forum-2013/1010/thumbnail.jp
Floral bud cold hardiness of southern highbush blueberry (\u3cem\u3eVaccinium corymbosum\u3c/em\u3e L. interspecific hybrids) in response to late season fertilization
The objectives were to identify the effects of late season fertilization on southern highbush blueberry (SHB) dormant floral bud cold hardiness, flower timing, and plant nutrient uptake. Treatments included two fertilizers 10-10-10 (Super Rainbow) and 46-0-0 (urea) and two cultivars, ‘Emerald’ and ‘Star’, grown in pine bark media. There were four late season fertilization treatments: 1) August: 10-10-10 fertilization (28 g/container applied in August); 2) September: 10-10-10 fertilization (20 g and 10 g/container applied August and September, respectively); 3) October: 10-10-10 fertilization (10 g/container applied monthly; August-October); 4) Urea: 46-0-0 fertilization (3 g/container applied August and September). Dormant root and shoot tissue were analyzed for mineral nutrients. Floral bud tissue was freeze tolerance (FT) tested and floral bud stages were recorded from 24 Jan. to 14 Mar. The FT of ‘Star’ was unaffected by fertilization treatments. In contrast, ‘Emerald’ on 17 Jan. was hardiest in October treatment (at -12.0 °C) and on 8 Feb., the hardiest floral buds of ‘Emerald’ were in September treatment (at -13.5 °C). Regardless of fertilizer, the treatments were similar in N concentration with some variation observed between roots and shoots. In both cultivars, late fertilization increased root N concentration. All fertilizer treatments in ‘Emerald’ bloomed earlier than ‘Star’. No significance was seen between treatments of bloom progression for ‘Emerald’. Treatment October advanced bloom progression in ‘Star’. This work demonstrates that urea and mid-October fertilization had no effect on floral bud cold hardiness and bloom timing was cultivar dependent
Applying Newton’s Law of Cooling When The Target Keeps Changing Temperature, Such As In Stratospheric Ballooning Missions
Newton’s Law of Cooling describes how a “small” system, such as a thermometer, comes to thermal equilibrium with a “large” system, such as its environment, as a function of time. It is typically applied when the environment is in thermal equilibrium and the conditions are such that the thermal decay time for the thermometer is a constant. Neither of these conditions are met when measuring environmental (i.e. atmospheric) temperature using a thermometer mounted in a payload lofted into the stratosphere under weather balloons. In this situation the thermometer is in motion so it encounters layer after layer of atmosphere which differ in temperature, and the changing environmental conditions can influence the thermal decay time “constant” for the thermometer as well. We have used Newton’s Law of Cooling in spreadsheet-based computer simulations to explore how thermometer readings react under these conditions, to better-understand how logged temperature records from stratospheric balloon flights during both ascent (relatively slow) and descent (much faster, especially at altitude) are related to actual environmental temperatures at various altitudes
Data Analysis and Curve Fitting to Determine the Regener-Pfotzer Maximum
Various data analysis methods were explored to more accurately and consistently determine the Regener-Pfotzer (RP) maxima for high altitude cosmic radiation. The radiation has been measured during 15 balloon flights using Geiger counters with five second accumulation times. Of the 15 flights, 10 of them included omni-directional counts data, and 8 of them included vertical coincidence counts data. Count data from altitudes greater than 10 km were analyzed to determine the maxima. The data analysis methods used were moving average filtering and summation of Geiger counts into one minute intervals. Moving average filtering did not give reliable results, so the summation method was chosen. Once the data were summed, several different curves were fit to determine where the RP maximum occurred. The curves tested include second and third order polynomials as well as cubic spline interpolation of the data averaged over 1 km intervals. Second order polynomial fitting did not fit the data well. Third order polynomials and cubic splines gave better results. Third order polynomial fitting was chosen due to its ease of use and the similarity of the results given by the cubic spline interpolation (within 1%). The omni-directional RP maxima occurred at an average altitude of 21.8 km ± 1.7 km, while the vertical coincidence RP maxima occurred at an average altitude of 18.5 km ± 1.1 km. In addition, the vertical coincidence RP maximum occurred at 65 hPa ± 9 hPa, while the omni-directional coincidence RP maximum occurred at 38 hPa ± 13 hPa

The Regener-Pfotzer Maxima during a Total Solar Eclipse
The Regener-Pfotzer (RP) maximum is the altitude at which cosmic radiation intensity is the greatest. A reduction of the altitude of the interaction layer, assumed to be measured by the RP maximum, has been suggested to account for a reduction in the secondary cosmic ray flux measured at the surface of the Earth during a total solar eclipse. To investigate this suggestion, high altitude cosmic radiation was measured using Geiger Mueller (GM) counters carried beneath weather balloons both before and during the total solar eclipse on August 21st, 2017. The pre-eclipse omnidirectional RP maxima occurred at an average altitude of 20.2 km and 20.4 km during the eclipse. The vertical coincidence pre-eclipse RP maxima occurred at an average altitude of 18.3 km and 18.0 km during the eclipse. Our results do not show any reduction in the altitude of neither the omnidirectional nor the vertical coincidence RP maxima outside the range of our observations before the eclipse
Wetland mapping and fen survey in the White River National Forest
Prepared for: John Proctor, Forest Botanist, White River National Forest.Includes bibliographical references (page 10).In January 2011, Colorado State University and the Colorado Natural Heritage Program (CNHP) contracted with the White River National Forest (WRNF) to complete wetland mapping and fen field surveys within the White River National Forest (WRNF). Since, 2008, CNHP has been working with the U.S. Fish and Wildlife Service's National Wetland Inventory (NWI) Program and numerous funding partners to create a comprehensive digital map of wetlands for the state of Colorado by 2015. The digitizing and mapping of the wetlands within the WRNF is integral to CNHP's goal to determine the extent and location of wetlands across the state. In addition to the digitizing of the 124 NWI maps, a subset of mapped wetlands consisting of 39 (original number was 25) fens were field surveyed during 2011. The data collected from this project will be added to the CNHP database of critical biological resources, including unique wetlands such as fens. This project will continue to build upon CNHP's past wetland survey and assessment projects
