Preliminary study of the flushing operations of the Langmann reservoir, Austria
No full textThe Langmann reservoir is part of the hydropower system in the river Teigitsch and in the reservoir loss of storage volume occurs. The reservoir was therefore flushed, but recently no permission is granted. The reason is the high sediment concentrations that have negative effects on the downstream region. An optimization of the flushing operations that reduces the negative effects and recovers most of the storage volume is required. Hence, insight in the flushing operations and identification of the key processes that determine the flushing efficiency are required. The reservoir is flushed by creating a riverine flow. The key processes that occur during flushing are classified as progressive erosion, retrogressive erosion and bank erosion. The flushing operations are in the maintenance phase; a channel is already formed and only recently deposited sediments are flushed out of the channel. A large peak in the sediment concentration at the transition of drawdown to riverine flow occurs. The Delft3D software is able to simulate the processes except for bank erosion. Bank erosion can be added to the model through an application that is under development. The model is very sensitive to the grid cell size, due to the small dimensions of the flushing channel. It is advised to decrease the grid cell size and to confine the grid to the flushing channel and the near surroundings as most erosion occurs within this area. The model also experiences problems in the water balance. The problems are caused by the rapid changes in water level, discharge and bottom level, but can be solved by adding and subtracting water to the model. The amount of sediment removed from the reservoir is underestimated. Data for calibration and verification are missing and therefore only the sensitivity to parameters that might increase the erosion is investigated. A measurement plan is set up in order to obtain the required data. The peak concentration is not shown in the model and so the model can not be used properly yet, to simulate different strategies that are implemented to minimize the sediment concentrations. Even though the model does not fully simulate the observed hydrological and morphological changes, it is felt that an important first step is taken in simulating the flushing operations. For the optimisation of the flushing operations a tube system combined with auxiliary channels that drain laterally is recommended. It is desirable to optimize the sediment management of the whole hydropower system in the river Teigitsch and make separate models of the three reservoirs. Pages 35-38 and Appendices B,C,D and E are removed due to secrecy.Hydraulic EngineeringCivil Engineering and Geoscience

Time evolution of the Luttinger model with nonuniform temperature profile
No full textWe study the time evolution of a one-dimensional interacting fermion system described by the Luttinger model starting from a nonequilibrium state defined by a smooth temperature profile T (x). As a specific example we consider the case when T (x) is equal to T-L (T-R) far to the left (right). Using a series expansion in epsilon = 2(T-R -T-L)/(T-L + T-R), we compute the energy density, the heat current density, and the fermion two-point correlation function for all times t >= 0. For local (delta-function) interactions, the first two are computed to all orders, giving simple exact expressions involving the Schwarzian derivative of the integral of T (x). For nonlocal interactions, breaking scale invariance, we compute the nonequilibrium steady state (NESS) to all orders and the evolution to first order in epsilon. The heat current in the NESS is universal even when conformal invariance is broken by the interactions, and its dependence on T-L,T-R agrees with numerical results for the XXZ spin chain. Moreover, our analytical formulas predict peaks at short times in the transition region between different temperatures and show dispersion effects that, even if nonuniversal, are qualitatively similar to ones observed in numerical simulations for related models, such as spin chains and interacting lattice fermions
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Steady States and Universal Conductance in a Quenched Luttinger Model
No full textWe obtain exact analytical results for the evolution of a 1+1-dimensional Luttinger model prepared in a domain wall initial state, i.e., a state with different densities on its left and right sides. Such an initial state is modeled as the ground state of a translation invariant Luttinger Hamiltonian Hλ with short range non-local interaction and different chemical potentials to the left and right of the origin. The system evolves for time t > 0 via a Hamiltonian Hλ′ which differs from Hλ by the strength of the interaction. Asymptotically in time, as t→ ∞, after taking the thermodynamic limit, the system approaches a translation invariant steady state. This final steady state carries a current I and has an effective chemical potential difference μ+- μ- between right- (+) and left- (−) moving fermions obtained from the two-point correlation function. Both I and μ+- μ- depend on λ and λ′. Only for the case λ= λ′= 0 does μ+- μ- equal the difference in the initial left and right chemical potentials. Nevertheless, the Landauer conductance for the final state, G= I/ (μ+- μ-) , has a universal value equal to the conductance quantum e2/ h for the spinless case
