Computing Paths in Massive Graphs
… methods for computing path-related queries in massive graphs. First, we study how to efficiently process reachability queries on distributed graphs, which check whether there is a path from one vertex to another. Real-world massive graphs are typically distributed across multiple data centers …

Massive stars in low metallicity environments
The evolution of massive stars has been a key field of research for many decades, as it has significant effects on a variety of astrophysical disciplines. Nonetheless, it is still widely uncertain due to a deficit of observational evidence to verify theoretical models. Recent surveys of the galaxy …

Rotation and magnetism in massive stars
Rotation has a number of important effects on the evolution of stars. Apart from structural changes because of the centrifugal force, turbulent mixing and meridional circulation can dramatically affect a star's chemical evolution. This leads to changes in the surface temperature and luminosity as …

Sublinear algorithms for massive data problems
… problems in the models that address massive data sets. The models include streaming algorithms, sublinear time algorithms, property testing algorithms, sublinear query time algorithms with preprocessing, or computing small summaries for large data. More precisely, we study the …

Tackling Algorithmic Problems on Massive Graphs
… algorithmic approaches for processing massive graphs under these constraints. Specifically, we focus on algorithms for the following graph problems. Motif Counting and Sampling: This involves developing efficient algorithms for counting and sampling small motifs (constant sized …

Mining Security Risks from Massive Datasets
… stealthier by concealing their behaviors in massive datasets. One the other hand, it is becoming more and more difficult for existing tools to handle massive datasets with various data types. This thesis presents the attempts to address the challenges and solve different security problems by …

Analysis of Wireless Networks With Massive Connectivity
… focus on the analysis of wireless networks with massive connectivity.</p><p>In the first part of the thesis, we seek to improve the energy efficiency (EE) of single-cell massive multiple-input multiple-output (MIMO) networks with joint antenna selection and user scheduling. We propose a two-step …

A Framework for Influencing Massive Virtual Organizations
This work presents a framework by which a massive multiagent organization can be controlled and modified without resorting to micromanagement and without needing advanced knowledge of potentially complex organizations. In addition to their designated duties, agents in the proposed framework perform …

Dense stellar systems and massive black holes
… predictions of this theory are black holes. Massive, dark objects are found in the majority of galaxies. Our own galactic center very contains such an object with a mass of about four million solar masses. Are these objects supermassive black holes (SMBHs), or do we need alternatives? The …

Forensic DNA phenotyping and massive parallel sequencing
… termed HIrisPlex-S, we successfully designed a Massively Parallel Sequencing (MPS) assay to complement the system and bring Next Generation Sequencing (NGS) to the forefront of forensic DNA analyses methods. Using Illumina’s MiSeq system enables the generation of HIrisPlex-S’s 41 variants using …

Massive Star Formation at High Spatial Resolution
This thesis studies the early phases of massive stars and their impact on the surrounding. The capabilities of continuum radiative transfer (RT) codes to interpret the observations are also investigated. The main results of this work are: 1) Two massive star-forming regions are observed in the …

Evaluation of massive weight loss body contouring
… Successful bariatric surgery will result in massive weight loss and ptotic skin, which can cause significant functional and psychological problems. As the number of cases of bariatric surgery increases, a corresponding number of massive weight loss patients will require plastic surgery. In …

Energetic Path Finding Across Massive Terrain Data
Before there were airplanes, cars, trains, boats, or bicycles, the primary means of transportation was on foot. Unfortunately, many of the trails used by ancient travelers have long since been abandoned. We present a software tool which can help visualize and predict where these forgotten trails …
