Evaluating Factors Controlling Damage And Productivity In Tight Gas Reservoirs

Besides zero-lag synchrony, group and cluster states are considered, enabling a description and study of complex synchronization patterns within the presented theory. Most prominently, synchronization takes place in the brain, where it is associated with several cognitive capacities but is - in abundance - a characteristic of neurological diseases. Adaptive control methods are developed, which allow the control of synchronization in scenarios where parameters drift or are unknown.

We discovered an interesting regioselectivity in an intramolecular Heck reaction, which we studied for a series of substrates that are unbiased in terms of the size of the newly formed ring, where very high levels of selectivity in relation to the new carbon-carbon bond are typically observed. This regioselective Heck reaction, combined with the reductive removal of the temporary amino-protecting group, allowed us to synthesize the Sceletium alkaloids: mesembrane, mesembranol and mesembrine.

By using a unique combination of iron catalyst and dichloride oxidant, various kind of naphthalene and phenanthrene derivatives were synthesized via annulation reaction with alkynes including direct C–H bond activation process. Iron catalysts in organic synthesis are strongly in demand because iron is non-toxic, inexpensive and the most abundant transition metal in the earth, although their use is still limited compared with that of rare, precious metals such as palladium, ruthenium and rhodium. Iron-Catalyzed Synthesis of Fused Aromatic Compounds via C–H Bond Activation. This thesis describes the first practical example of iron catalysis in the carbon–hydrogen bond activation reaction to synthesized fused aromatic ring compounds.

Initially, an established 'phase portrait' method, useful for visualising and calculating phase equilibria of polymer-blend films, is generalised to systems without convenient simplifying symmetries. A key feature underlying the theoretical models is the unification of one-dimensional thermodynamic phase equilibria with film evolution phenomena in two- and three dimensions.

In this thesis the static and dynamic properties of GaAs-based oxide-confined VCSELs emitting at 850 nm and 980 nm are analyzed and general rules for achieving energy-efficient data transmission using VCSELs at any wavelength are derived.Energy-Efficient VCSELs for Optical Interconnects These rules are verified in data transmission experiments leading to record energy-efficient data transmission across a wide range of multimode optical fiber distances and at high temperatures up to 85°C.. Energy-efficient data communication is one of the most important fields in “Green Photonics” enabling higher bit rates at significantly reduced energy consumption per bit.

Next, he moves on to answer the crucial question: is the intrinsic bispectrum going to screen the primordial signal in the CMB? In doing so, he introduces SONG, a new and efficient code for solving the second-order Einstein and Boltzmann equations.The Intrinsic Bispectrum of the Cosmic Microwave Background Nominated as an outstanding thesis by Professor Robert Crittenden of the Institute of Cosmology and Gravitation in Portsmouth, and winner of the Michael Penston Prize for 2014 given by the Royal Astronomical Society for the best doctoral thesis in Astronomy or Astrophysics, this work aims to shed light on one of the most important probes of the early Universe: the bispectrum of the cosmic microwave background.

In addition, the author employs the charge-vortex duality to show that the capacitance of the Mott insulator near the superfluid to insulator phase transition serves as a probe for the dual vortex superfluid stiffness. The numerical methods employed are described in detail, in particular a worm algorithm for O(N) relativistic models and methods for numerical analytic continuation of quantum Monte Carlo data.

Clinical trials of glucose sensors in the urine samples of diabetic patients demonstrated that they offer superior performance compared to commercial high-throughput urinalysis devices. The sensors employ off-axis Bragg diffraction gratings of ordered silver nanoparticles and localized refractive index changes in poly (2-hydroxyethyl methacrylate) and polyacrylamide films. Holographic Sensors.

The state-dependent phase shift mediates a deterministic universal quantum gate between the atom and one or two successively reflected photons, which is used to generate entangled atom-photon, atom-photon-photon, and photon-photon states out of separable input states. In particular, it demonstrates the nondestructive detection of an optical photon. Then, quantum bits are encoded in the polarization of the laser pulse and in the Zeeman state of the atom.

This extends the range of TDDFT, which on its own cannot tackle many of the large and interesting systems in materials science and computational biology. To achieve this, the author combines the linear response formulation of time-dependent density functional theory (TDDFT) with linear-scaling techniques known from ground-state density-functional theory. Computing the Optical Properties of Large Systems. This work addresses the computation of excited-state properties of systems containing thousands of atoms.

Tight gas reservoirs have very low permeability and porosity, which cannot be produced at economical flow rates unless the well is efficiently stimulated and completed using advanced and optimized technologies.
