Retrospective review of urinary lipoarabinomannan (ULAM) in the diagnosis of disseminated tuberculosis (TB) in medical inpatients at a district level hospital in Cape Town
… co-infection. In 2016 Urinary Lipoarabinomannan (ULAM) became available in SA to expedite the diagnosis and treatment of Tuberculosis (TB) in this vulnerable population. Objectives To describe the experience at a district level hospital following the availability of ULAM testing for investigating …

Thermische und langreichweitige Effekte in nichtlinearer Gitterdynamik mit Anwendungen in der Bio- und Nanophysik
… drei Bereiche, in denen die bekannte Fermi-Pasta-Ulam-Kette, die diskrete nichtlineare Schroedingergleichung und zweidimensionale Fermi-Pasta-Ulam-Ebenen mit Graphit-aehnlichen Wechselwirkungspotenzialen der Teilchen untersucht werden. Im ersten Teil werden fruehere Studien zur thermischen …

Phononic Frequency Combs
… in physical systems described by Fermi-Pasta-Ulam dynamics. The phononic frequency combs is mediated by nonlinear coupling between a primary driven mode and one or more parametrically excited internal modes. We provide experimental evidence for the formation of such phononic frequency combs in …

Distances on rankings: from social choice to flash memories
… theory, we introduce permutation codes in the Ulam metric that were not previously reported in the literature. Compared to known codes, the proposed codes can handle more diverse types of errors, including arbitrary charge-drop errors as well as other errors that affect a single cell, such as …

On groups and initial segments in nonstandard models of Peano Arithmetic
… analogous to the result of Baer, Schreier and Ulam for infinite symmetric groups. The external structure of nonstandard cyclic groups of prime order is identified as that of infinite dimensional rational vector spaces and the normal subgroup structure of nonstandard projective special linear …

Investigating chaos by the generalized alignment index town (GALI) method
… periodic orbits of the well-known Fermi-Pasta-Ulam-Tsingou lattice model. In particular, we study how the values of the GALIs depend on the width of the stability island and the system's energy. We find that the asymptotic GALI values increase when the studied regular orbits move closer to the …

Topological Approaches to Chromatic Number and Box Complex Analysis of Partition Graphs
… namely Bedge(︁P(33))︁, and applying the Borsuk-Ulam theorem to compute its Z2-index. This provides a robust topological lower bound for the chromatic number of P(33), termed the Lovász bound. We have verified the absence of such an S4 within certain sections of Bedge(︁P(33))︁. We also validated …

Computational methods for multi-omic models of cell metabolism and their importance for theoretical computer science
To paraphrase Stan Ulam, a Polish mathematician who became a leading figure in the Manhattan Project, in this dissertation I focus not only on how computer science can help biologists, but also on how biology can inspire computer scientists. On one hand, computer science provides powerful …

Novel Monte Carlo Methods for Large-Scale Linear Algebra Operations
… First of all, we revisit the classical Ulam-von Neumann Monte Carlo algorithm and derive the necessary and sufficient condition for its convergence. To support a broad family of linear systems, we develop Krylov subspace Monte Carlo solvers that go beyond the use of Neumann series. New …

Stochastic recruitment strategies for controlling artificial muscles
This thesis presents a new architecture for controlling active material actuators inspired by biological motor recruitment. An active material is broken down into many small fibers and grouped together to form one large actuator. Each of these fibers is held in a binary state, either relaxed or …

Sensorless temperature estimation and control of Peltier devices
Peltier devices, also known as thermoelectric devices (TEDs), are solid state junctions of two dissimilar materials in which heat transfer and electrical conduction are coupled. A current running through a TED causes heat to flow; likewise, the presence of an external temperature gradient will …

Functional thinking in cost estimation through the tools and concepts of axiomatic design
There has been an increasing demand for cost estimation tools which aid in the reduction of system cost or the active consideration of cost as a design constraint. The existing tools are currently incapable of anticipating the unseen or latent effects of design changes made in an effort to cut …
