pQCD energy loss and thermal field theory in small systems
… of peripheral heavy-ion collisions as well as in smaller colliding systems. The glaring exception to this list of observations of QGP signatures in small systems is the partonic energy loss. However, current theoretical descriptions of partonic energy loss are ill-adapted to small systems. This …

Energy loss and theoretical uncertainties in small quark-gluon plasmas
… have been observations of QGP signatures in much smaller collision systems—including proton proton, and proton heavy-ion collisions—wherein QGP was not expected to form. Experimentally measuring suppression in small systems is more difficult than in large systems, motivating the need for …

An environmental study of the Lourens River estuary
… knowledge was collated. The Lourens estuary is a small system opening into False Bay, Southwestern Cape; it is almost entirely enclosed within AECI security fences and access to the public is restricted. Physicochemical parameters exhibit seasonal variations and the estuary may be marine dominated …

Schopenhauer's Buddhism: A Historical-Philosophical Inquiry
… the Buddhist concept of palingenesis into his system, which generated several contradictions in his late works such as the second (1844) and the third edition (1859) of The World as Will and Representation, and Parerga and Paralipomena (1851), including their posthumous versions. I agree with …

Hadronic gas description of relativistic heavy ion collisions incorporating exact conservation of quantum numbers
… canonical ensemble could be justified. For a small system however, corrections arising solely from exact strangeness and baryon number conservation cannot be neglected. Analytic results for the partition function and the particle numbers are presented. A detailed numerical evaluation is made. …

Designing a higher layer protocol for small distributed microcontroller systems using the control area network protocol
… with designing a Higher Layer Protocol (HLP) for small distributed microcontroller systems using a well-established network protocol: the Controller Area Network (CAN) protocol which, currently, is widely used in the automation industries. Steps were taken to investigate three popular HLPs based …

A probabilistic model for estimating demand for selected existing rural community hospitals that may be facing closure in West Virginia
… through application of the Huff model that in a small system of hospitals and patients, each patient location (i.e., zip code) will send patients to nearly every hospital. The model predicted sufficient demand for two of the four hospitals studied. Conventional methodologies were then compared to …

Partonic rescatterings during jet fragmentation in the QCD vacuum
High energy collisions of small systems like Proton-Proton ($pp$) and Proton-Lead ($p$Pb) have demonstrated surprising evidence for the existence of collectivity where it had previously been thought not to occur. Specifically, the medium produced by these collisions at the Large Hadron Collider …

Machine Learning Force Fields for Molecular Chemistry
… principles computational modelling of molecular systems is a long-standing pursuit in the scientific community. It has traditionally been tackled by developing approximate solutions to quantum mechanics. Simulations using these electronic structure based methods can be highly accurate but are …

Modeling and Analysis of the Effects of Impairments in Fiber Optic Links
In digital communication systems, several types of impairments may be introduced to the signal. These impairments result in degraded system performance; for example, high bit-error-rate or power penalty. For optical communication systems, in this thesis, these impairments are categorized into four …

Quantum Monte Carlo: Applications of the Twist -Averaged Boundary Conditions and the Calculation of Forces
… studying the properties of physical and chemical systems. The application of QMC to extended systems subjects to finite size effects because the simulation is often done with a small system in a super cell geometry. Periodic boundary condition is commonly used in such a setup which leads to large …

Application of quantum Monte Carlo methods to molecular potential energy surfaces
… highly accurate methods scale poorly with system size (n<sup>7</sup> or higher) and are mostly not well parallelized for calculations with multiple processors. One alternative method that has more favorable scaling with system size and is well parallelized is a computational technique …

Spin Polarization of Ground State Electron Gas at Low Densities
… In order to reduce the finite size effect at small system sizes, we apply Twist Averaged Boundary Conditions on electron gas. To our knowledge, this is the first application on continuum systems. With the above methods, we first calculate ground state energies of electron gas at the …
