Spontaneous Flow Transitions in Active Polar Gels
(2011-11-20)
Active polar gels are a type of viscoelastic soft material formed by polar filaments which are constantly driven out of equilibrium by the consumption
of chemical fuel such as ATP. Following the approach of Voituriez et ...
Quantum Simulation of a Transverse-Field Ising Model
(2010-12-20)
A popular model that have been used to study ferromagnetism is the Ising Model which is an arrangement of spins along a particular direction and with discrete values of + 1 . 1-D Ising model doesn't show a phase transition ...
Effects of Bending on the Optoelectronic Properties and Failure Mechanism in Organic Photovoltaics
(2011-12-15)
This research investigates the effects of bending on the electrical, optical, structural and mechanical properties of flexible organic photovoltaic (OPV) cells. Bulk heterojunction organic solar cells were fabricated on ...
Molecular Dynamics Simulation of Transport of Encapsulated Drug Through a Lipid Bilayer
(2014-12-15)
Most anticancer drugs are polar, cytotoxic and have complicated structures which cause difficulty in their penetration through the cell membrane. This presents a serious problem in chemotherapy. Is it possible to use carbon ...
Analysis of Magneto Hemodynamics of Blood in a Stenosed Artery
(2016-06-17)
Human body responds to physical activities, external temperature, external magnetic field, and other factors by homeostatically adjusting its blood flow in order to deliver nutrients such as oxygen and glucose to every ...
Thermodynamic Analysis of Unsteady Mhd Boundary Layer Flow With Slip Over a Permeable Surface
(2016-06-12)
Magnetohydrodynamics (MHD) boundary layer flow problems have become important in industrial manufacturing processes such as plasma studies, chemical engineering, electrochemistry, polymer processing, petroleum industries, ...
Surface Modification of Polymeric Biomaterials for Cell/Tissue Integration
(2016-06-17)
This thesis presented the surface modification of polydimethyl siloxane (PDMS) to enhance surface wettability and surface roughness. Physical and chemical modifications were performed on cured surfaces of PDMS and PDMS-based ...
Electro-Magnetic Duality, Magnetic monopoles and Topological Insulators
(2013-05-13)
The Maxwell equations of electrodynamics acquire an additional symmetry if one assumes the existence of hypothetical particles-magnetic monopoles,
carrying a magnetic charge. The additional internal symmetry is the ...
The Design of an On-Chip Silicon Photonic Diode
(2013-05-13)
This work presents numerical calculation of electromagnetic waves in unidirectional on-chip silicon optical diodes. An original optical diode, designed by Wang et. al. [Opt. Express. 19, 26948-26955 (2011)], is based on ...
Fundamentals of Laser Dynamics
(2013-05-13)
The thesis presents the modeling and simulation of three types of lasers namely; Semicondoctor laser, Solid state laser and CO 2 laser. The rate equations were derived and simulated to examine the dynamic behaviour of the ...
