UBT International Conference

The most fundamental human needs of water are for drinking, cooking and personal hygiene. In order to fulfill these needs, the quality of the water used should cause no risk to human health. The quality of the water in nature also affects the condition of ecosystems all living organisms depend on. At the same time, humans use water bodies as convenient sinks for the disposal of domestic, industrial and agricultural wastewaters. This, of course, degrades the quality of those water bodies. Water resources management involves the monitoring and management of water quality as much as the monitoring and management of …


Conformational Switching And Graph Grammar: Abstract Models Of Self-Assembly, Arnab Dutta May 2012

Conformational Switching And Graph Grammar: Abstract Models Of Self-Assembly, Arnab Dutta

Math Theses

Abstract models of self-assembly are mathematical models that capture the behavior of natural or artificial self-assembling systems. In 1995, conformational switching in self-assembling mechanical systems was introduced and an abstract model of self-assembling systems, conformational switching model, was later developed where assembly instructions are written as rules representing the conformational changes of self-assembling components. In 2004, another abstract model named graph grammar was developed to self-assemble a prespecified graph structure by generating a grammar or a set of rules. We first provide the concepts related to the abstract models of self-assembly, followed by a brief history of the development of …


Detailed Modeling Of Soot Size Distribution Evolution And Pollutant Formation Inside Aircraft And Diesel Engines, Chowdhury Golam Moniruzzaman Jan 2012

Detailed Modeling Of Soot Size Distribution Evolution And Pollutant Formation Inside Aircraft And Diesel Engines, Chowdhury Golam Moniruzzaman

Legacy Theses & Dissertations (2009 - 2024)

Combustion emission of soot and pollutant gas species contributes to poor regional air quality near emission sources and to climate change. It is important to understand the formation mechanism and time evolution of these pollutants inside the combustion engine, through detailed modeling of combustion chemistry and microphysics as well as comparison with observation. In this thesis, two multi-zone gas parcel combustion engine models, one for aircraft engines and another for diesel engines, have been developed to study soot size distribution evolution and pollutant formation inside the engines as well as emissions. The models take into account size-resolved (sectional) soot aerosol …
