**Abstract:**

Fine-grain reconfigurable devices suffer from the time needed to load the configuration bitstream. Even for small bitstreams in partially reconfigurable FPGAs this time cannot be neglected. In this article we survey the performance of the factors that contribute to the reconfiguration speed. Then, we study an FPGA-based system architecture and with real experiments we produce a cost model of Partial Reconfiguration (PR). This model is introduced to calculate the expected reconfiguration time and throughput. In order to develop a realistic model we take into account all the physical components that participate in the reconfiguration process. We analyze the parameters that affect the generality of the model and the adjustments needed per system for error-free evaluation. We verify it with real measurements, and then we employ it to evaluate existing systems presented in previous publications. The percentage error of the cost model when comparing its results with the actual values of those publications varies from 36% to 63%, whereas existing works report differences up to two orders of magnitude. Present work enables a user to evaluate PR and decide whether it is suitable for a certain application prior entering the complex PR design flow.

**Abstract:** We first review the methodology of the error-avoiding paradigm for the generation of gauge theoretic non abelian connections a.k.a holonomies, over a control manifold that effectively generates a minimal universal set of gates capable of simulating any quantum computation circuit. A family of iso-spectral hamiltonians on N dimensional Hilbert spaces are considered over an associated set of control parameters geometrically identified with a Grassmann manifold and adiabatically traced loops in the manifold are considered. Loops can give rise to u(N) Lie algebra valued 1-forms connection that can generate efficiently 1 and 2 qubit universal quantum gates. Further the 3 qubit generic state vector in Hilbert space C^3 is shown to admit a Gr(4,2) Grassmann manifold parametrization that is associated with points on a Klein quartic algebraic variety. Special lower dimensional restrictions of the variety and their unitary symmetries are investigated.

Professor Garofalakis, among many other distinctions throughout his career, is the first ECE faculty with 10,000+ citations to his work, and he exemplifies the level of excellence which the School of ECE faculty, students and staff strive to achieve.

**Abstract:**

Vortices are presented are presented, starting from multivalued complex functions exhibiting singularities and proceeding to consider the Hilbert space formed by orbital angular momentum (OAM) states that provides representation to ISO(2) Euclidean algebra generators identified as the relevant physical observables. Next, the three classes of physical vortices, i.e. light, electron and atom vortices, are considered and basic construction techniques such as computer generated fork holograms, spiral phase plates, beam splitters, and the paraxial wave equation Laguerre-Gauss solutions are discussed. The mechanical effects of vorticity are investigated next by studying interaction models coupling matter to light carrying OAM of fractional or irrational angular momentum or with so-called C shaped beams. The resulting dynamical equations of motion appeared to be generalizations of the well known Raman-Nath equations of light-matter interaction.
