description: Békés megye agrárjellege a gazdasági fejlettséget is determinálja. A megye agrárszektorában megtermelt 1 főre jutó bruttó hozzáadott érték jelentősen meghaladja az országos átlagot, de a megye gazdasági teljesítményének növekedése elmarad az országosétól, az egy főre jutó GDP értékében nő a rés. A térség lemaradása azonban megfelelő aktivitással és pályázati szakszerűséggel megállítható. A megye pályázati forrásokból való részesedése és az egy pályázaton elnyert támogatás összege növekedett. A megye pályázati aktivitása magas, a megyék felső harmadában van. A támogatások odaítélésében a bírálók a nagyobb bekerülési összegű (komplexebb) pályázatokat részesítették előnyben. Ugyanakkor kedvezőtlen, hogy az egy projektre jutó támogatás összege, az AVOP-ból finanszírozott fejlesztések esetén alacsonyabb, mint az országos, ami kisebb volumenű egyedi fejlesztéseket jelez. A pályázatok jelzik, hogy a megye felkészült az uniós pályázatokon való eredményes részvételre, ami a 2007-2013-as időszakában meghozhatja a hasznát: segíti a megye gazdasági felzárkózását, benne az agrártermelés és az arra ráépülő feldolgozóipar, illetve szolgáltató ágazatok fejlődését. ----------------- Békés county’s agricultural nature determines its state of economic development. The gross value added per head produced by the county’s agricultural sector significantly exceeds the national average. However, growth in the county’s economic results falls behind the rest of the country and the gap is widening in terms of GDP per head. The region’s lag could be halted through appropriate activism and professional subsidy applications. The county’s share of subsidy resources and the amount granted per application have increased. Its application activity is high, falling into the top third of all counties. In assessing subsidy grants, the judges favour the more complex applications. At the same time it is a disadvantage that the subsidy amount available for one project, in the case of developments financed through AVOP (Agricultural and Regional Development Operative Programme), is lower than nationally, indicating a smaller volume of individual developments. The applications show that the county is ready for successful participation in EU grant-making processes, which could be useful in the 2007-2013 period. It will help the county close the economic gap, including in agricultural production and the processing industry that is built on it, as well as assisting in the development of the service sector.

Product development and production, distribution, planning, and organisation, are based on intensive investigation of consumer demands and product-related expectations. The key to success may be thorough knowledge of the market and the information acquired on producers’ methods of pork and poultry breeding, the maintenance technologies used, and the animals being kept.
title: An empirical evaluation of 2D and interactive 3D terrain visualisations for cycling maps
Creators: name: Cook, Myles Edward

Year: 2017
Subjects: subject: Thematic Cartography

description: The last two decades have borne witness to considerable growth in the availabilityof interactive and 3D cartographies. However, questions about their true usefulness andusability remain, with the results of associated research drawing conflicting conclusions.This knowledge deficit is especially apparent within the design of cycling maps and cycleroute-planners. 3D cartography has enabled new forms of terrain visualisation for these usescenarios, but their usability relative to traditional methods of terrain visualisation is not yetfully understood. In response to this deficit, this thesis aimed to assess the relative usability(measured in terms of efficiency, effectiveness and user-preference) of 2D and 3D elevationvisualisations for cycle route-planners. In order to fulfil this aim, an empirical user-study was conducted with 36 participants.Participants were asked to solve a range of typical cycle route-planning tasks (related toheight detection, slope detection and climb estimation), for a variety of 2D (arrow, colour,elevation profile) and interactive 3D (3D elevation profile and 3D terrain model) elevationvisualisations. Study participants also provided feedback on their visualisation preference foreach of the tasks. These usability factors were assessed using a digital survey, which allowedinclusion of interactive 3D visualisations within a controlled experimental setting, whilst alsoautomatically logging user response times, user answers, and preference feedback. The findings demonstrated significant usability differences between individual2D and 3D elevation visualisations, although it was not possible to broadly state that onedimensionality was more or less `usable¿ than the other. Further, the usability of eachvisualisation was found to be strongly dependent upon the type of route-planning task.However, the 2D elevation profile was most efficient in the widest range of scenarios, andthose (generally 3D) visualisations which demanded interaction or high levels of cognitiveprocessing were least efficient. The results also showed that those visualisations which placedthe lowest cognitive load on the user were most effective; this factor appears to have had agreater influence on efficacy than the dimensionality of the visualisations. For all task types,users preferred 2D visualisations, most especially the 2D elevation profile.

Ebből 67 található a vizsgált Dunaszerdahelyi járásban, melyek eredményesen versenyeznek a „nyugati” üzlethálózatokkal. A szövetkezeti hálózat egységeinek előnye a fogyasztókhoz való közelség és ismertség Gyengeségei között viszont a logisztikai és marketing hiányosságok az elsődlegesek. A kiskereskedelmi üzletláncok között 38%-os súlyával a legerősebb pozíciót foglalja el. A szövetkezet azzal, hogy mentesíti egységeit a raktározás, feldolgozás, csomagolás terhei alól, tovább növelheti piaci súlyát. ------------- The three types of Jednota Slovensko COOP chain store consists of 2,388 units. Of these, 67, which compete successfully with “Western” chain stores, can be found in the Dunaszerdahely district examined. The advantage of the association network units is their closeness to and knowledge about their consumers. Among their weaknesses, the primary ones are shortcomings in logistics and marketing. With its 38% share, the association holds the strongest position among small retail chain stores. It can further increase its market share by freeing its units from the burdens of storage, processing and packing.

description: This document provides a summary of fault parameterisation decisions made for the faults comprising the fault-source model (FSM) for 2023 National Seismic Hazard Assessment (NSHA23). As with the NSHA18, the FSM for the NSHA23 implementation requires the following parameters: simplified surface trace, dip, dip direction, and slip-rate. As paleoseismic data exist for only a few of the approximately 400 faults within the Australian Neotectonic Features database, we use the Neotectonic Domains model as a framework to parametrise uncharacterised faults.

description: We argue that, due to the specific form of the interaction potential between electronic guiding centers, a bubble crystal (BC) with basis may be energetically more favorable than the usual bubble solid. This new BC has well-defined normal eigenmodes, and remains energetically favorable when the effects of finite sample thickness and of screening by electrons in lower LLs are taken into account.

Regularization of Inverse Problems: Deep Equilibrium Models versus Bilevel Learning

description: Variational regularization methods are commonly used to approximate solutions of inverse problems. In recent years, model-based variational regularization methods have often been replaced with data-driven ones such as the fields-of-expert model (Roth and Black, 2009). Training the parameters of such data-driven methods can be formulated as a bilevel optimization problem. In this paper, we compare the framework of bilevel learning for the training of data-driven variational regularization models with the novel framework of deep equilibrium models (Bai, Kolter, and Koltun, 2019) that has recently been introduced in the context of inverse problems (Gilton, Ongie, and Willett, 2021). We show that computing the lower-level optimization problem within the bilevel formulation with a fixed point iteration is a special case of the deep equilibrium framework. We compare both approaches computationally, with a variety of numerical examples for the inverse problems of denoising, inpainting and deconvolution.

description: It is shown that the peculiar features observed in the low-temperature phase diagrams of ZrZn_2, UGe_2, and MnSi can be understood in terms of a simple mean-field theory. The nature of the ferromagnetic transition changes from second order to first order at a tricritical point, and in a small external magnetic field surfaces of first-order transitions emerge which terminate in quantum critical points. This field dependence of the phase diagram follows directly from the existence of the tricritical point. The quantum critical behavior in a nonzero field is calculated exactly.

description: By combining the Wigner function formalism of relativistic quantum kinetic theory with fundamental equations of relativistic magnetohydrodynamics (MHD), we present a novel approach to determine the proper time evolution of the temperature and other thermodynamic quantities in a uniformly expanding hot, magnetized, and weakly interacting plasma. The aim is to study the contribution of quantum corrections to this evolution. We first determine the corresponding Wigner function in terms of the solution of the Dirac equation in the presence of a constant magnetic field. Using this function, we then compute the energy-momentum tensor of the above-mentioned plasma, which eventually yields its energy density and pressure. Plugging these quantities in the energy equation of relativistic MHD, we arrive, after choosing an appropriate coordinate system, at a differential equation for the temperature as a function of the proper time. The numerical solution of this equation leads finally to the proper time evolution of the temperature. The latter is then used to determine the evolution of a large number of thermodynamic quantities in this expanding and magnetized plasma. We compare our results with other existing results from relativistic MHD. We also comment on the effect of point to point decaying magnetic fields on the thermodynamic properties of this plasma.

description: A cost functional involving the eigenvalues of an elastic structure, that is described by a multi-phase-field equation, is optimized. This allows us to handle topology changes and multiple materials. We prove continuity and differentiability of the eigenvalues and we establish the existence of a global minimizer to our optimization problem. We further derive first-order necessary optimality conditions for local minimizers. Moreover, an optimization problem combining eigenvalue and compliance optimization is also discussed.

description: The boundary cancellation theorem for open systems extends the standard quantum adiabatic theorem: assuming the gap of the Liouvillian does not vanish, the distance between a state prepared by a boundary cancelling adiabatic protocol and the steady state of the system shrinks as a power of the number of vanishing time derivatives of the Hamiltonian at the end of the preparation. Here we generalize the boundary cancellation theorem so that it applies also to the case where the Liouvillian gap vanishes, and consider the effect of dynamical freezing of the evolution. We experimentally test the predictions of the boundary cancellation theorem using quantum annealing hardware, and find qualitative agreement with the predicted error suppression despite using annealing schedules that only approximate the required smooth schedules. Performance is further improved by using quantum annealing correction, and we demonstrate that the boundary cancellation protocol is significantly more robust to parameter variations than protocols which employ pausing to enhance the probability of finding the ground state.

Why Solve the Hamiltonian Constraint in Numerical Relativity?

Publisher: name: arXiv
Year: 2004
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The indefinite sign of the Hamiltonian constraint means that solutions to Einstein's equations must achieve a delicate balance--often among numerically large terms that nearly cancel. If numerical errors cause a violation of the Hamiltonian constraint, the failure of the delicate balance could lead to qualitatively wrong behavior rather than just decreased accuracy. This issue is different from instabilities caused by constraint-violating modes. Examples of stable numerical simulations of collapsing cosmological spacetimes exhibiting local mixmaster dynamics with and without Hamiltonian constraint enforcement are presented.

description: The domain dynamics and spin-spin correlation of 2D ferromagnets Cr2X2Te6 (X=Si, Ge) are investigated by a composite magnetoelectric method. The magnetic field-temperature phase diagrams for both in-plane and out-of-plane magnetic fields disclose a triple point around TC and 1 kOe, where ferromagnetic, paramagnetic, and spin-polarized phases coexist. The magnetoelectric signal shows peak features at the phase boundaries and reaches the maximum at the triple point, suggesting significant enhancement of spin-spin correlations at this point. A comparison between two systems reveals that the spin-spin correlations in Cr2Si2Te6 are stronger than that in Cr2Ge2Te6.

description: Im Rahmen dieser Arbeit wurde ein optischer Aufbau basierend auf einem Digital Micromirror Device (DMD) entwickelt und charakterisiert, um statische und dynamische optische Dipol-Potenziale für eindimensionale (1d) Quasi-Kondensate auf einem Atomchip zu realisieren. Die Kombination optischer Dipol-Potenziale mit magnetischen Potenzialen verbindet die höhe Flexibilität von optischen Fallen mit den Vorteilen von Magnetfallen wie z.B. effektives evaporatives Kühlen und die Anwendbarkeit von "radio frequency dressed state" Potenzialen. Um die maximale Flexibilität der Potenziale zu erreichen, wurde eine automatisierte Muster-Optimierung für den DMD entwickelt und hohe Graustufen-Auflösung durch Anwendung eines Fourier-Raum-Filters erreicht. Das aufgebaute System ermöglicht das Erforschen neuer Aspekte der Dynamik von 1d Quantensystemen in Bereichen der Quantenvielteilchenphysik bis hin zu Quantenthermodynamik.
description: In this work, an optical system based on a digital micromirror device (DMD) is designed and built in order to realize arbitrary static and dynamic optical dipole potentials for one-dimensional (1d) quasi-condensates of 87Rb created on an atom chip. The hybrid trapping configuration realized by the superposition of this optical potential with the magnetic confinement of the atom chip combines the high flexibility of optical dipole traps with the advantages of magnetic trapping, such as effective evaporative cooling and the application of radio frequency dressed state potentials. To achieve maximal flexibility, automated pattern optimization procedures and selective Fourier space filtering for high grayscaling resolution are developed. This setup will enable the investigation of many different model systems addressing questions from quantum many-body physics to quantum thermodynamics.

description: Recently developed quantum algorithms suggest that in principle, quantum computers can solve problems such as simulation of physical systems more efficiently than classical computers. Much remains to be done to implement these conceptual ideas into actual quantum computers. As a small-scale demonstration of their capability, we simulate a simple many-fermion problem, the Fano-Anderson model, using liquid state Nuclear Magnetic Resonance (NMR). We carefully designed our experiment so that the resource requirement would scale up polynomially with the size of the quantum system to be simulated. The experimental results allow us to assess the limits of the degree of quantum control attained in these kinds of experiments. The simulation of other physical systems, with different particle statistics, is also discussed.

description: Proton radiotherapy can assure a more precise treatment of cancer patients, but is more sensitive to uncertainties than conventional radiotherapy using photons. Therefore, non-invasive in-vivo dose verification is desired. The only clinically applied method for 3D dose verification in proton therapy is positron emission tomography (PET) monitoring. Because of the different underlying physical processes, the dose cannot be deduced directly from the measured PET data. The measured PET data needs to be compared to predicted PET data, generated by simulations. The GATE software provides a useful tool for the simulation of b+-activity induced by proton irradiation. The present work focuses on GATE simulations suitable for the workflow at the MedAustron facility. The implemented modality at MedAustron is an offline PET, i.e. the PET scanner is not located in the treatment room. This thesis investigates which nuclides need to be included in the simulation, and what impact the time structure and biological washout have. Finally, a new simulation approach in GATE, the CrossSectionProductionActor (CS-Actor), was evaluated. To investigate these topics, the b+-activity following the irradiation of a PMMA target and a patient's head were simulated. Also, a full radiotherapy plan was simulated using a modelled human head, based on a CT (computed tomography) scan, as the target. The evaluation of the simulations suggests that for range verification, the simulation of 11C might be sufficient. However, if a higher accuracy is needed, the inclusion of 13N is recommended. The importance of including the irradiation time and biological washout was shown as well. The irradiation time, during which production and decay of nuclides take place simultaneously, is the only aspect not yet included in GATE. An extension of GATE and a further examination of the implemented biological washout model is needed. It was found that the CS-Actor is faster and more accurate than the established Actor that fully relies on a Monte Carlo method, a stochastic numerical technique. Apart from some smaller problems, the CS-Actor could be an applicable alternative. At the moment, the CS-Actor is only available for the simulation of 11C and 15O. Therefore, an extension of the Actor to simulate 13N is desirable.

description: We extend the problem of $(1+1)$ circular dilaton gravity to include charged particles. We examine the two (charged) particle case in detail and find an exact equilibrium solution. We then extend this to $N-$particles and obtain a solution for this case as well. This class of solutions corresponds to $N$-particles of the same mass, spaced evenly around the circle with charges chosen so that the electric field satisfies $E^{2}=$constant. We discuss the relation of these solutions to the previous uncharged equilibrium solutions and examine the behavior when the number of particles is large. We comment on the challenges in further generalizing the solutions we obtain.

Experimental study of cavitating flow influenced by heat transfer from heated hydrofoil

description: This study experimentally investigated the influence of heat transfer from a heated hydrofoil on cavitating flow to understand the evaporation phenomenon under high-heat-flux and high-speed conditions. A temperature difference was generated between the hydrofoil and mainstream by installing an aluminum nitride heater in a NACA0015 hydrofoil fabricated from copper. A cavitation experiment was performed in a high-temperature water cavitation tunnel at the Institute of Fluid Science, Tohoku University. The effect of heating on cavitating flow was evaluated by changing the mainstream velocity and pressure, namely the cavitation number, at a fixed heater power of 860 W. Results showed that the heat transfer from the hydrofoil affected cavitating flow in terms of the cavity length, cavity aspect, and periodicity. The effect on the cavity length became stronger at a lower velocity owing to a higher hydrofoil temperature. The variation in periodicity implied that the heating effect reduced the unsteadiness of cavitation. A modified cavitation number was proposed by considering the heat transfer from the heated wall. A thermal correction term was derived by considering that the fluid temperature close to the heated hydrofoil was affected by the turbulent convective heat transfer between the mainstream and hydrofoil. The corrected cavitation number can be considered as a parameter that describes the cavity length in the isothermal and heated cases in a unified expression.

description: Exceptional points (EPs), the degeneracy point of non-Hermitian systems, have recently attracted great attention after its ability to greatly enhance the sensitivity of micro-cavities is demonstrated experimentally. Unlike the usual degeneracies in Hermitian systems, at EPs, both the eigenenergies and eigenvectors coalesce. Although some of the exotic properties and potential applications of EPs are explored, the range of EPs studied is largely limited by the experimental capability. Some of the systems, e.g. with higher-order EPs, are hard to achieve with conventional simulations. Here we propose an extendable method to simulate non-Hermitian systems on the quantum circuits, where a wide range of EPs can be studied. The system is inherently parity-time (PT) broken due to the non-symmetric controlling effects and post-selection. A sample circuit is implemented in a quantum programming framework, and the phase transition at EP is demonstrated. Considering the scalable and flexible nature of quantum circuits, our model is capable of simulating large scale systems with higher-order EPs. We believe this work may lead to broader applications of quantum computers and provide a tool to the studies for non-Hermitian systems and the associated EPs.

This conjecture states modularity of D3 equations for smooth Fano threefolds with Picard group Z. More precisely, we find counting matrices of prime two-pointed Gromov-Witten invariants for them. For this we use the method that lets us find Gromov-Witten invariants of complete intersections in varieties whose invariants are (partially) known.

A segmentation network and a discriminator network were trained jointly, and only the segmentation network was used for prediction. The segmentation network integrates a newly designed MRF block into a variation of multi-residual U-net. The discriminator takes the product of the original CT and the prediction/ground-truth as input and classifies the input into fake/real. The segmentation network and discriminator network can be trained jointly as a whole, or the discriminator can be used for fine-tuning after the segmentation network is coarsely trained. Multi-scale pooling layers were introduced to preserve spatial resolution during pooling using less memory compared to atrous convolution layers. An adaptive loss function was proposed to enhance the training on small or low contrast organs. The accuracy of modeled contours was measured with the Dice similarity coefficient (DSC), Average Hausdorff Distance (AHD), Average Surface Hausdorff Distance (ASHD), and relative Volume Difference (VD) using clinical contours as references to the ground-truth. The proposed ARPM-net method was compared to several stateof-the-art deep learning methods.

description: The rise of deep neural networks offers new opportunities in optimizing recommender systems. However, optimizing recommender systems using deep neural networks requires delicate architecture fabrication. We propose NASRec, a paradigm that trains a single supernet and efficiently produces abundant models/sub-architectures by weight sharing. To overcome the data multi-modality and architecture heterogeneity challenges in the recommendation domain, NASRec establishes a large supernet (i.e., search space) to search the full architectures. The supernet incorporates versatile choice of operators and dense connectivity to minimize human efforts for finding priors. The scale and heterogeneity in NASRec impose several challenges, such as training inefficiency, operator-imbalance, and degraded rank correlation. We tackle these challenges by proposing single-operator any-connection sampling, operator-balancing interaction modules, and post-training fine-tuning. Our crafted models, NASRecNet, show promising results on three Click-Through Rates (CTR) prediction benchmarks, indicating that NASRec outperforms both manually designed models and existing NAS methods with state-of-the-art performance.

description: We calculate the motion of binary mass systems in gravity up to the fourth post--Newtonian order. We use momentum expansions within an effective field theory approach based on Feynman amplitudes in harmonic coordinates by applying dimensional regularization. We construct the canonical transformations to ADM coordinates and to effective one body theory (EOB) to compare with other approaches. We show that intermediate poles in the dimensional regularization parameter $\varepsilon$ vanish in the observables and the classical theory is not renormalized. The results are illustrated for a series of observables for which we agree with the literature.

Tying in CP and Flavor Violations with Fermion Masses and Neutrino Oscillations

description: In this paper we explore the possibility that (a) fermion masses, (b) neutrino oscillations, (c) CP non-conservation and (d) flavor violations get intimately linked to each other within supersymmetric grand unification based on SO(10) or an effective G(224) = SU(2)_L\times SU(2)_R\times SU(4)^c symmetry. We extend the framework proposed previously by Babu, Pati and Wilczek (BPW) which successfully described fermion masses and neutrino oscillations, to include CP violation. Assuming flavor universal SUSY breaking parameters at M^* >~ M_{GUT}, and that CP violation arises through phases in the fermion mass matrices, we show how the presence of GUT threshold induces new and calculable CP and flavor violations. Including SM and SUSY contributions, we find that the BPW framework can correctly account for the observed flavor and/or CP violations in Δm_K, Δm_{B_d}, S(B_d-> J/ψK_S) and ε_K. While SUSY-contribution is small ( ϕK_S) to be in the range +(0.65-0.73), close to the SM prediction. The model yields Re(ε'/ε)_{SUSY}\approx +(4-14)\times 10^{-4}; the relevance of this contribution can be assessed only when the associated matrix elements are known reliably. The model also predicts that the electric dipole moments of the neutron and the electron should be discovered with improvements in current limits by factors of 10 to 100.

Assessment of clinical, cellular and molecular determinants in sarcoidosis
Creators: name: Anantharajah, Anthea
Publisher: name: The Australian National University

description: Sarcoidosis is a complex, multisystem inflammatory disease with highly varied presentations, organ involvement and natural history. Its aetiology has remained enigmatic and previous attempts at investigating the cellular and genetic mechanisms that give rise to this disease have yielded conflicting and inconsistent results, largely due to the heterogeneous composition of patient cohorts studied. This project set out to address the problem of phenotypic heterogeneity in sarcoidosis in order to facilitate a more productive investigation into cellular and molecular determinants associated with this disease. We hypothesised that extreme or homogeneous presentations of sarcoidosis would be associated with distinct cellular and molecular characteristics. Through the establishment of a quaternary referral sarcoidosis clinic, patients with diverse presentations of sarcoidosis underwent clinical phenotyping to identify subgroups with consistent clinical characteristics and disease outcomes. Our phenotypic model identified 3 subgroups (neurosarcoidosis, sarcoid uveitis and hepatosplenic sarcoidosis) that were significantly associated with organ limited disease or associated with a distinct presentation that correlated with organ involvement. Patients with a newly described presentation of isolated tattoo and ocular inflammation were also studied as a distinct subgroup. Genetic analysis which focussed on NOD2 variants, demonstrated a significant association between the carriage of P268S and the development of sarcoid uveitis and multisystem disease. Patients with the extreme clinical phenotype of neurosarcoidosis were found to possess a baseline peripheral cellular signature consisting of reduced effector T regulatory cells and increased T effector memory, Th1 and Th2 cells, that was distinct from other clinical phenotypes of sarcoidosis. Finally, we identified global downregulation of chemokine receptor CXCR5 on lymphocyte populations in patients with active tattoo uveitis which normalised upon remission. This finding of chemokine receptor dysregulation is likely to be significant in a disease process that is characterised by organ restricted inflammation. Our results have demonstrated the utility of clinical phenotyping in heterogeneous disease processes. Further investigation will be required to clarify the mechanistic implications of the genetic and cellular associations identified.

description: Data representation is crucial for the success of machine learning models. In the context of quantum machine learning with near-term quantum computers, equally important considerations of how to efficiently input (encode) data and effectively deal with noise arise. In this work, we study data encodings for binary quantum classification and investigate their properties both with and without noise. For the common classifier we consider, we show that encodings determine the classes of learnable decision boundaries as well as the set of points which retain the same classification in the presence of noise. After defining the notion of a robust data encoding, we prove several results on robustness for different channels, discuss the existence of robust encodings, and prove an upper bound on the number of robust points in terms of fidelities between noisy and noiseless states. Numerical results for several example implementations are provided to reinforce our findings.

description: The full set of stationary states of the mean field of a Bose-Einstein condensate in the presence of a potential step or point-like impurity are presented in closed analytic form. The nonlinear Schrödinger equation in one dimension is taken as a model. The nonlinear analogs of the continuum of stationary scattering states, as well as evanescent waves, are discussed. The solutions include asymmetric soliton trains and other wavefunctions of novel form, such as a pair of dark solitons bound by an impurity.
title: Perceptual modeling: factors influecing speech intelligibility in a multitalker environment and applications in speech separation

description: The aim of this thesis is the investigation of speech intelligibility in multitalker environments, where the challenge for the listener is to focus on one speaker in the presence of simultaneous interfering talkers or background noise in order to follow the conversation. In general, this is not a difficult task for normal hearing people, but it can be a challenge for people suffering from hearing impairment. Furthermore, it still remains a problem for machines to deal with interfering speech signals. Within this thesis, different speech segregation algorithms and their mathematical and statistical background are presented. There are different approaches of processing interfering speech signals. Motivated by the powerful ability of the auditory system to analyze and segregate incoming sounds, Computational Auditory Scene Analysis (CASA) aims at replicating the different auditory processing stages. Another essential approach in the context of the separation of interfering speech signals which differs from CASA is Blind Source Separation (BSS) which uses results from Statistics and Information Theory to separate a signal mixture into its sources. In the experimental part of the thesis, a speech intelligibility (SI) test was performed which was implemented in MATLAB® (R2015b). The aim was the investigation of factors affecting Speech Intelligibility where the main focus was on analyzing attributes of the masker signals and their influence on speech perception of the target signal. 12 normal hearing listeners participated in the test and the task was to determine the target signals in the presence of different masker signals. The target signals consisted of 14 nonsense-syllables (e.g. 'affa' or 'assa') from the Oldenburger Logatome Corpus (OLLO) spoken by four female persons. The masker signals included sentences from the Oldenburger Satztest (e.g. 'Britta verleiht elf alte Bilder'), the International Speech Test Signal (ISTS) and Speech Shaped Noise (SSN). The test was evaluated using a two-way repeated measures analysis of variance (ANOVA) in SPSS® Statistics (24) including the two within-subject factors "Signal-to-Noise Ratio" (SNR) and "Masker Type". The results showed a significant main effect in both factors (p<0.001) and in further research, ANOVA also demonstrated a significant influence of the factors "Number of Maskers" (p<0.001) and "Spectral Diversity of the Masker" (p<0.001) on speech intelligibility.
