L1 adaptive control within Learn-to-Fly
… theory were required to enable the linear reference systems to be updated (which leads to switched reference systems) as the modeling algorithm adjusts the vehicle model and to be parameterized (which can be captured by linear parameter-varying (LPV) models) by different flight conditions. …

THE REAL WORK OF ASSESSMENT: EQUITY-CENTERED SENSEMAKING IN DUAL LANGUAGE LEADERSHIP
… is positioned under competing normative reference systems and how educational leaders interpret and act upon those representations within accountability-driven contexts. Grounded in Quantitative Critical Race Theory, the Biliteracy Trajectories framework, Culturally Sustaining Pedagogy, …

Verifiable Adaptive Control Solutions for Flight Control Applications
… solution and is extended to time-varying reference systems to support augmentation of gain-scheduled baseline controllers. Compared to conventional adaptive controllers, L1 control has the following advantages: i) it has guaranteed uniformly bounded transient response for system's both …

Overlap
… of a design ordered by two overlapping reference systems. A mixed-use building serves as the project to resolve the complexities of overlap that result from rotation, and to explore ideas of transparency.

Multiple model estimation for linear stochastic hybrid systems with non-homogeneous transition probabilities
… estimation, filtering, and multiple model based systems is presented. More specifically, the often made assumption of a constant time-invariant mode transition probability matrix is relaxed. Recent work done in the area of non-Markov jump stochastic hybrid systems is explored, including semi- …

Assessing Wetland Restoration on the Delmarva Peninsula using Vegetation Characteristics
… particularly when comparing to natural reference systems. As part of the Mid-Atlantic Conservation Effects Assessment Project, 15 depressional wetlands on the Delmarva Peninsula of Maryland and Delaware were surveyed for above-ground vegetation and seed bank community composition, annual …

Interactions of pure aluminium hydrolytic species Keggin polyoxocations and hydroxide with biologically relevant molecules
… species with biomolecules. Pure aluminium reference systems (aluminium monomers, Keggin aluminium polyoxocations - Al13 and Al30, and aluminium hydroxide suspensions) were used for systematic mechanistic studies of the sol-gel transformation of aqueous solutions of aluminium-ions into …

Nakano Flow: Designing for Spatial and Temporal Flow in urban Tokyo
… the site strategies of geometric spatial reference systems and sequenced movement spaces. The new Nakano Station plaza will exist as a platform and scaffold space, upon which new uses and modes of development can be explored and adapted to best accommodate the demands of future urban Tokyo.

EVALUATION OF HYDROLYTIC ENZYMES IN THE DESIGN OF ORAL DRUG DELIVERY SYSTEMS
… a powder (Sternzym® C13030) into drug delivery systems (DDSs) were initially assessed on HPMC-based hydrophilic matrices (HMs) for oral prolonged release. The study was carried out on tableted matrices containing increasing amount of enzymatic product, so that its effect, also in terms of …

Das Lichtpulsersystem des elektromagnetischen CsI(Tl)-Kalorimeters des Babar-Detektors
… absolute intensity is measured by two special reference systems whose stability is monitored using a radioactive source. During the construction phase the light pulser was used to check the electronics in order to ensure its functioning before the insertion of the calorimeter into the detector …

L1 adaptive control for nonlinear and non-square multivariable systems
… nonlinear, and non-square multivariable systems. The objective is to extend the L1 adaptive control framework to cover a wide class of underactuated systems with uniform performance and robustness guarantees. This dissertation starts by investigating some structural properties of …

Cluster Dynamical Mean-Field Theory: Applications to High-Tc Cuprates and to Quantum Chemistry
… study problems in strongly correlated electron systems, including high-Tc cuprate superconductors as well as a few quantum chemical reference systems. We start with an introduction to the background of the interacting electron systems, followed by a brief description on the current understanding …

Graphical pangenomics
… analyze new genomic data in the context of a reference genome. This approach distorts our image of the inferred genome, an effect which we describe as reference bias. To mitigate reference bias, I repurpose graphical models previously used in genome assembly and alignment to serve as a …

Towards a new South African geodetic datum
… to determine absolute co-ordinates (in a global reference system) with an accuracy of about one metre. One purpose of the present study is to present a way of combining the various Doppler observations to the TRANSIT satellites and to derive a single set of geocentric co-ordinates for the …
