Along with subterranean maps, the new site will also include environmental data that will help users gather more data on climate change. “In discussions about climate change, the world’s oceans are often overlooked despite being an integral part of the issue. About one third of the carbon dioxide that we emit into the atmosphere ends up in the oceans,” says Schmidt. It was no coincidence that A...

This work describes an auto-calibrated method for parallel imaging with spiral trajectory. The method is a k-space approach where an interpolation kernel, accounting for coil sensitivity factors, is derived from experimental data and used to interpolate the reduced data set in parallel imaging to estimate the missing k-space data. For the case of spiral imaging, this interpolation kernel is def...

-Most algor i thms in 3D computer vision rely on the pinhole camera model because of its simplicity, whereas virtually all imaging devices int roduce certain amoun t of nonlinear distort ion, where the radial dis tor t ion is the most severe part. Common approach to radial dis tor t ion is by the means of polynomial approximat ion, which introduces distortion-specific pa ramete rs into the came...

While most of the microwave background fluctuations on angular scales greater than a few arcminutes were generated at z > 800, the low redshift universe does distort the microwave background. Since the Sloan Digital Sky Survey (SDSS) traces the structures in the low-redshift universe, we can gain additional insights into the physics of the low-redshift universe by cross-correlating microwave ba...

Software maintenance accounts for a significant proportion of the cost of the software life cycle. Software engineers must spend a considerable amount of time understanding the software system functional attributes and non-functional (e.g., availability, security, etc.) aspects prior to performing a maintenance task. In this paper, we propose a dynamic analysis approach to recover availability ...

Metadata snapshots are a favored method for gaining filesystem insights due to their small size and relative ease of acquisition compared to access traces [2]. Since snapshots do not include an access history; typically they are used for relatively simple analyses such as file lifetime and size distributions, and researchers still gather and store full block or file access traces for any higher...

Energy profiling is a means to effectively understand the power behavior of smartphone applications. However, no tool that effectively combines portability, accuracy and automation has been proposed yet. In this thesis a new approach is proposed, which sets the basis for such a tool by solving a trace synchronization problem. TRAM (TRAce Merger) uses the event trace from a mobile device and the...

Characterizing the communication behavior of large-scale applications is a difficult and costly task due to code/system complexity and their long execution times. An alternative to running actual codes is to gather their communication traces and then replay them, which facilitates application tuning and future procurements. While past approaches lacked lossless scalable trace collection, we con...
