Cloud-Based Analytic Element Groundwater Modeling, Jacob Baird Fullerton
Cloud-Based Analytic Element Groundwater Modeling, Jacob Baird Fullerton
Theses and Dissertations
Managing groundwater resources requires computer modeling software, which in turn brings its own costs in education and usage fees. Although many groundwater modeling programs can be obtained at relatively inexpensive rates the hidden costs of software training remain high in general. What has been done is to make both the software and training available online for free, but this method delegates all responsibility to the users for both accessing the software in addition to learning how to use it properly. In this research the accessibility of groundwater models has been improved upon by creating a web app of an open …
Mitigating Interference During Virtual Machine Live Migration Through Storage Offloading, Morgan S. Stuart
Mitigating Interference During Virtual Machine Live Migration Through Storage Offloading, Morgan S. Stuart
Theses and Dissertations
Today's cloud landscape has evolved computing infrastructure into a dynamic, high utilization, service-oriented paradigm. This shift has enabled the commoditization of large-scale storage and distributed computation, allowing engineers to tackle previously untenable problems without large upfront investment. A key enabler of flexibility in the cloud is the ability to transfer running virtual machines across subnets or even datacenters using live migration. However, live migration can be a costly process, one that has the potential to interfere with other applications not involved with the migration. This work investigates storage interference through experimentation with real-world systems and well-established benchmarks. In order to …
Privacy Protection On Cloud Computing, Min Li
Privacy Protection On Cloud Computing, Min Li
Theses and Dissertations
Cloud is becoming the most popular computing infrastructure because it can attract more and more traditional companies due to flexibility and cost-effectiveness. However, privacy concern is the major issue that prevents users from deploying on public clouds. My research focuses on protecting user's privacy in cloud computing. I will present a hardware-based and a migration-based approach to protect user's privacy. The root cause of the privacy problem is current cloud privilege design gives too much power to cloud providers. Once the control virtual machine (installed by cloud providers) is compromised, external adversaries will breach users’ privacy. Malicious cloud administrators are …
Investigating Virtual Globes For A Prototype Community Archive Of 3d Subsurface Data, Derek C. Whitman
Investigating Virtual Globes For A Prototype Community Archive Of 3d Subsurface Data, Derek C. Whitman
Theses and Dissertations
Geoscience data sharing and processing is very advanced in terms of surface data. Subsurface data sharing has not received the attention that surface data sharing has received and so there are fewer applications or software packages which focus on it. This research is funded by the NSF EarthCube GEO Domain program in an effort to develop a continental-scale repository of 3D subsurface data to facilitate the sharing of complex 3D data and to enable the development of geoprocessing tools and workflows that operate on that data. The work in this thesis is a small part of the EarthCube project with …
