Controlling dust charge in complex plasmas 

McKinlay, Michael (2022-07-21)
A dusty plasma is a four-component plasma consisting of electrons, ions, neutral gas, and microparticles (dust) which collect charge from the surrounding plasma environment. They can be found in every regime of plasma ...

Database Indexing for Skyline Computation, Hierarchical Relational Database, and Spatially-Aware SPARQL Evaluation Engine 

Wang, Chih-Jye (2015-12-10)
Computerized databases are ubiquitous and play an important role in many software projects. The efficiency of these systems are crucial in applications they support. Data indexing is the key to efficient data retrieval in ...

Investigation of Probe-Induced Dust Voids in a Weakly Magnetized Dusty Plasma 

LeBlanc, Spencer (2019-12-06)
Dust voids, or regions free of dust grains surrounded by dusty plasmas, have been observed in a wide array of experimental configurations, from microgravity systems, to 3-dimensional dust clouds, to 2-dimensional monolayers. ...

Microparticle Dynamics in the Presence of Externally Imposed, Ordered Structures in a Magnetized Low-Temperature Plasma 

Hall, Taylor (2019-11-26)
Dusty plasmas are a type of plasma which consists of charged microparticles suspended in a background plasma. In the presence of a strong magnetic field, dusty plasmas have been observed to develop new patterned formations ...

Particle Charge Determination in a Magnetized Dusty Plasma Flow 

Funk, Dylan (2023-05-04)
Dusty plasmas consist of components typically found in a plasma (electrons, ions and neutral particles) as well as micrometer sized dust particles. The structural and dynamic properties of a dusty plasma system are ...

Transmission-Type Impedance Probes for Use in Complex Plasmas 

Doyle, Brandon (2023-12-04)
Impedance probes measure electron density (ne ) and electron temperature (Te) by interpreting frequency-dependent transmission or reflection spectra (S21 or S11) of radiofrequency (RF) signals of low power (10−5 W). This ...
