Quantum dynamics in classical constant-temperature baths.
(2012)In this dissertation the formulation of various integration algorithms is studied, with a view to simulate quantum-classical systems in contact with a thermal bath. In particular focus is given to the constant temperature ... -
Quantum dynamics in the partial Wigner picture.
(2013)The Wigner formalism can be used to provide a representation of quantum dynamics in a classical-like phase space. However, there are many cases, such as when dealing with spin systems in a dissipative environment, in ... -
Quantum key distribution--Undergraduate curriculum.
(2017)Quantum Key Distribution (QKD) is one of the technological applications of quantum mechanics. The technology allows two users to securely establish an unbreakable key. The key is used to encrypt and decrypt sensitive ... -
Quantum machine learning for supervised pattern recognition.
(2017)Humans are experts at recognising patterns in past experience and applying them to new tasks. For example, after seeing pictures of a face we can usually tell if another image contains the same person or not. Machine ... -
Quantum simulation of open quantum systems.
(2016)Over the last two decades the field of quantum simulations has experienced incredible growth, which, coupled with progress in the development of controllable quantum platforms, has recently begun to allow for the ... -
Radiating solutions with heat flow in general relativity.
(1994)In this thesis we model spherically symmetric radiating stars dissipating energy in the form of a radial heat flux. We assume that the spacetime for the interior matter distribution is shear-free. The junction conditions ... -
The rates and mechanisms of substitution from Ru(II) complexes with different non-leaving ligand environments.
(2019)Results from multiple studies have confirmed that the nature of ligands on the metal centre determines the properties of an anti-cancer agent in a biological environment. Ligands affect solubility, substitution reactivity, ... -
A ray tracing study of VLF phenomena.
(1997)Whistlers have, for many years, been used as probes of the ionosphere and magnetosphere. Whistlers received on the ground have been shown (Smith [1961], Helliwell [1965]) to have propagated, in almost all cases, through ... -
Reactions and reactivity of allyl and related carbamates.
(1997)Carbamate chemistry has flourished since the 1980's which saw the introduction of the carbamoyl group by Hoppe and co-workers, prominent researchers in this area, as a suitable moiety for the activation and stabilisation ... -
Reactions and reactivity of allylic and benzylic carbamates.
(1995)The purpose of this investigation was to study the effect of the carbamate group on the reactions and reactivity of substituted 1,1-diphenylmethane and a,ro-diphenyl allylic compounds. A series of carbamates were prepared ... -
The redox and co-ordination chemistry of some dinuclear diphosphazane- bridged derivatives of ruthenium.
(1991)Abstract available in pdf file. -
Reduction of aldehydes and ketones to their corresponding alcohols in 1-butyl-3-methylimidazolium tetrafluoroborate.
(2017)The use and release of volatile organic solvents (VOS) to the atmosphere have become detrimental to both human health and his environment. In addition, the non-recyclability and the excessive consumption of these solvents ... -
Refractive effects in phase objects and associated phenomena.
(1994)The effect of the refraction of a laser beam propagating through three different phase objects, i.e. a laser produced plasma and two different gas media, is investigated in this thesis. It is shown that these effects ... -
Review of solar energy inclusion in Africa : a case study of Nigeria.
(2017)This work reviews solar energy inclusion in Africa using Nigeria as a case study. It reviewed studies made on viability, challenges and solutions associated with making solar energy a viable energy option in Nigeria. ... -
Rhenium(I) and -(V) complexes of N-donor heterocyclic chelates.
(2016)Abstract available in PDF file. -
Rhodium-catalyzed and uncatalyzed synthesis of boronate esters and their subsequent utility in the Suzuki realm.
(2008)This study has shown that alkythioboranes 1,3,2-dithiaborolane and 1,3,2-dithiaborinane, disproportionated significantly during their synthesis. Their interaction with 1-octene has been investigated, and the rate constants, ... -
A robust air refractometer for accurate compensation of the refractive index of air in everyday use.
