Impact of aging on asphalt pavement performance, ductility and DSR measurements
(Texas A&M University, 2002)
In this work, Asphalt binder from Texas, SH 21 was extracted and recovered in different years. This binder was studied and compared with lab-aged binder. This study mainly included dynamic shear rheometer (DSR) measurements ...
Coke profile and effect on methane/ethylene conversion process
(Texas A&M University, 2002)
The objective of this study was to investigate the coke profile with respect to time on stream and the change of product distribution due to catalyst deactivation. A fixed bed reactor was used to conduct this investigation. ...
The viscoelastic properties of linear-star blends
(Texas A&M University, 2000)
In order to understand the nature of polydispersity and characterize the effect of branching architecture, the model blend of linear and star polymer, which is the simplest branched polymer, is contrived. In this blend ...
Accuracy of truncated Leiden and Berlin virial expansions for pure gases and sealing joints between silicon carbide and stainless steel
(Texas A&M University, 2003)
Pure gases such as methane, carbon dioxide and steam were used to make comparisons between Leiden and Berlin virial expansions for the calculation of the compressibility factor, fugacity coefficient and enthalpy residual. ...
The effects of obstacle geometry on jet mixing in releases of silane
(Texas A&M University, 2000)
Releases of silane into air and the effects of obstacles were modeled with the Computational Fluid Dynamics (CFD) code, FLUENT. First the CFD code simulated the release of a free turbulent jet of silane into air to assure ...
Development of a relational chemical process safety database and applications to safety improvements
(Texas A&M University, 2000)
Industrial accidents still show a major concern to both the public and the environment. It has been a governmental objective to minimize these accidents. Several rules and regulations have emerged to reduce the impacts ...
Conversion of methane and acetylene into gasoline range hydrocarbons
(Texas A&M University, 2000)
Conversion of methane and acetylene to higher molecular weight hydrocarbons over zeolite catalyst (HZSM-5) was studied The reaction between methane and acetylene successfully produced high molecular weight hydrocarbons, ...
Frequency domain photon migration measurements: a method to size powders and detect active pharmaceutical ingredients in blending operations
(Texas A&M University, 2004)
Stringent rules and legal interpretations continuously encourage the pharmaceutical industry to innovate effective and practical methods to ensure the safety of its products to consumers. Most recently the final blending ...
Optimization of antiretroviral therapy for HIV infected patients by simultaneous analysis of immune restoration and serious side effects
(Texas A&M University, 2002)
The development of potent antiretroviral drugs has substantially improved life expectancy and quality of life for HIV infected patients. However, current HIV drugs do not induce complete viral eradication, requiring long ...
A new Lyapunov design method for nonlinear process control
(Texas A&M University, 2001)
The present research work proposes a new nonlinear controller synthesis approach that is based on the methodological principles of Lyapunov design. In particular, it introduces a notion of short-horizon model-based prediction ...
