Untersuchung stationärer Betriebsgrößen des Drehstromasynchron-Linearmotors für Synchrongeschwindigkeiten unter 3m/s
Drehstromasynchron-Linearmotoren (DLM) werden kommerziell mit der kleinsten Synchrongeschwindigkeit von 3,0m/s angeboten. Die Stillstandskraft des DLM mit der kleinsten Baugröße liegt bei ca. 30N, so dass damit eine Glasschiebetür mit einer Masse bis 20kg angetrieben werden kann. Bei der üblichen …

The Theory and Applications of Discrete Constrained Optimization Using Lagrange Multipliers
… of our proposed theory and methods. DLM is able to solve systematically general discrete, continuous and mixed-integer constrained benchmarks, which is a task not achieved by previous methods. DLM has found better multiplierless filter-bank designs that improve over all of Johnston's …

Dynamic Bayesian models for modelling environmental space-time fields
… we implement the dynamic linear modelling (DLM) approach in spatial interpolation and find various potential problems with that approach. We develop software to implement our approach. Secondly, we implement a Bayesian spatial prediction (BSP) approach to model spatio-temporal ground-level …

Telecommuting in the developing world: a case of the day-labour market
… who belong to the Day-labour Market (DLM), which is also made up of employers, job-brokers and intermediary organisations. The DLMs’ main activities involve a great deal of travelling in search of jobs by workers and a search for workers by employers. These travels place heavy economic …

Bayesian treed distributed lag models
… throughout pregnancy. The distributed lag model (DLM) is a statistical method commonly implemented to estimate an exposure-time-response function by regressing the outcome on repeated measures of a single exposure over a preceding time period, for example, mean exposure during each week of …

Parameterfreies hierarchisches Graph-Clustering-Verfahren zur Interpretation raumbezogener Daten
… Diese Vorgehensweise stellt ein Beispiel für die DLM-Interpretation auf der Grundlage eines spezifischen Modells dar und kann zur schnellen Generierung von groben 3D-Stadtmodellen oder als Vorabinformation zur bildgestützten 3D-Gebäuderekonstruktion verwendet werden. Des weiteren stellen wir …

Optimal Energy Management of a SAGD Microgrid Participating in a Volatile Electricity Market
… are provided by an EMS forecaster using Bayesian DLM and timeseries ARIMA forecast models. The DLM has the ability to incorporate several exogenous inputs with resultant improvements: accuracies of up to 85% are achieved. The EMS provides optimal economic dispatch for generation and storage units …

Analyses of Indices of Abundance for Important Groundfish Species in the Northern Gulf of Mexico from 1987-2009, Relative to Shrimp Bycatch; with Age and Growth of Three Sciaenid Species
… fishery as bycatch. Delta-lognormal modeling (DLM) was used to determine the relative abundance of these species over a twenty-three year time period from 1987-2009 using SEAMAP survey data collected by the National Marine Fisheries Service.</p> <p>Six covariates were used in each submodel …

Three-dimensional multi-scale hydraulic fracturing simulation in heterogeneous material using Dual Lattice Model
… unfractured stage. A novel Dual Lattice Model (DLM) is proposed for hydraulic fracture simulation by coupling a solid lattice model with a fluid lattice model. From DLM simulations of hydraulic fracturing of the classical penny shape crack problem under hydrostatic condition, the heterogeneities …

Establishing A Quantitative Foundation for Exactly Constrained Design
… window. <p>The direct linearization method (DLM) is another mathematical method used to quantify information in an EC design. While EC designs provide many advantages, some EC assemblies may be "better" than others. A quantitative measure of goodness is developed in this thesis using the DLM. …

Forecasting value-weighted real returns of TSE portfolios using dividend yields
… the two methods agree, however, the regression DLM approach does slightly better in comparison with the methods of Fama and French in terms of standarized forecast errors.

Quantification of acid loads and delineation of hydrochemical facies at a phreatic mine spoil aquifer
… situ alkaline injection were investigated at the DLM coal mine, Alton West Virginia. These included spatial and temporal investigations into hydrochemical controls that were initiated with reclamation efforts. Approaches included the delineation of hydrochemical facies and analysis of time series …

Electro hydrodynamic manipulation of the process of self-assembly of particles at fluid-fluid interfaces
… using a distributed Lagrange multiplier method (DLM) and the electric force acting on the particles is calculated by integrating the Maxwell stress tensor (MST) over the particle surfaces. One of the key features of the DLM method is that the fluid-particle system is treated implicitly by using a …

Understanding and Predicting Water Quality Impacts on Coagulation
… charge, and particle removal. A diffuse layer (DLM) surface complexation model was formulated to simultaneously predict sorption of NOM and other key species, including silica, calcium, and carbonate alkalinity. Predictions of surface potential were used to estimate zeta potential and resulting …

Basic studies for the incorporation of uranium in sediments
… study shows that the surface complexation model DLM can predict the major three types of uranium behaviours: (1) the increase of uranium adsorption at pH range between 5 and 6.5, (2) the maximum of adsorption at nearly neutral pH and (3) the decrease of uranium adsorption between pH 8 and 11.
