Developing A Website For The Sword Of The Spirit Using An Agile Development Approach, James Smith Jan 2017

Developing A Website For The Sword Of The Spirit Using An Agile Development Approach, James Smith

Senior Honors Theses and Projects

This creative project was created using an agile development process. Working in coordination with an organization called the Sword of the Spirit, a website was developed for their use. Using the agile approach, multiple iterations of the project were created and brought back to the organization for testing and feedback. The website was developed and is currently working here: https://sites.google.com/view/sosovemight/home.

For this project, a website, administrative email, and data collection and storage process were created. Security was added to ensure only registered profile holders would be able to view the information on the website. This was developed solely for the …


Smartphone Based Ubiquitous Sensing Platform Leveraging Audio Jack For Power And Communication, Ranjana Joshi Jan 2017

Smartphone Based Ubiquitous Sensing Platform Leveraging Audio Jack For Power And Communication, Ranjana Joshi

Dissertations and Theses @ UNI

With the popularization of smartphones, various smartphone centric ubiquitous sensing applications, which use a smartphone in conjunction with external sensors for data acquisition, processing, display, communication, and storage, have emerged. Because smartphones do not have a universal data interfaces, many ubiquitous sensing applications use the earphone and the microphone channels of the 3.5mm audio interface for data communications so that they can work with various types of smartphones. The earphone channels of the 3.5mm audio interface can only send AC signal out of a smartphone, hence DC power needs to be harvested from the earphone channels.

In this research, based …


Surface Ozone And Its Precursors At Summit, Greenland: Comparison Between Observations And Model Simulations, Yaoxian Huang, Shiliang Wu, Louisa J. Kramer, Detlev Helmig, Richard E. Honrath Jan 2017

Surface Ozone And Its Precursors At Summit, Greenland: Comparison Between Observations And Model Simulations, Yaoxian Huang, Shiliang Wu, Louisa J. Kramer, Detlev Helmig, Richard E. Honrath

Michigan Tech Publications, Part 1

Recent studies have shown significant challenges for atmospheric models to simulate tropospheric ozone (O3/and its precursors in the Arctic. In this study, ground-based data were combined with a global 3-D chemical transport model (GEOS-Chem) to examine the abundance and seasonal variations of O3 and its precursors at Summit, Greenland (72.34° N, 38.29° W; 3212 ma.s.l.). Model simulations for atmospheric nitrogen oxides (NOx/, peroxyacetyl nitrate (PAN), ethane (C2H6/, propane (C3H8/, carbon monoxide (CO), and O3 for the period July 2008-June 2010 were compared with observations. The model performed well in simulating certain species (such as CO and C3H8/, but some significant …
