Modelling of laser plasma interaction with applications to particle acceleration and radiation generation

The development of laser systems with ultra-high intensities has allowed the study of the relativistic interaction of laser light and ionized matter, plasmas, as well as opened up prospects for compact particle accelerators, generation of high intensity X-ray, XUV radiation, and probing QED-effects, which are present in the high intensity regime. To describe laser matter interaction, it is necessary to self-consistently account for the paths of a large number of particles and the corresponding electromagnetic fields, with the addition of stochastic effects at high laser intensities. Although analytical work can capture the essence of the dynamics in a range of situations, the rich dynamics in laser-plasma interaction results in that numerical modelling, and in particular the Particle-In-Cell (PIC) method, is critical to gain a detailed description of the dynamics. This is a stochastic method in which phase-space is sampled with macro-particles and allows for efficient modelling of high dimensional problems, but has limitations due to statistical noise. For some applications, for example shock acceleration and instability growth, continuum methods, i.e. solving the Vlasov-Maxwell system of equations on a phase-space grid, may be preferable to accurately describe the plasma dynamics. In the first two papers in this thesis, we address the problem of implementing efficient continuum methods for the Vlasov-Maxwell system of equations. Furthermore, we treat ion shock acceleration using continuum methods. In the following papers, we address scalings of the electron spectrum in the electron sheath, formed at the vacuum-plasma boundary through the interaction of a relativistic laser and moderately overdense plasma. This is important to determine the spectral properties of high harmonic radiation generated from the laser plasma interaction. We also explore electron wakefield acceleration driven by laser pulses with wavelength in the X-ray regime generated from laser plasma interaction in the moderately overdense regime. By reducing the wavelength, the quantum parameter is enhanced, leading to comparable electron and photon energies already at moderate relativistic amplitudes although with more infrequent emission of photons than at optical wavelengths, preventing radiation losses from becoming a roadblock for the acceleration process.
On minimal projections generated by isometries of Banach spaces

Let В be a real Banach space. Let A be a linear isometry in В which has a fixed point. The present paper is inspiried on a fact that is known to some degree but not precisely discused in any source, i.e., if the space В is represented as a direct (topologie) sum of Im(7 — A) and Ker(/ — A) [where 7 is the identity map of B], then the projection P onto Im(7 — A) along Ker(7 — A) is the minimal projection ( г) (cf. below, Theorem 1.1). In connection with this fact two problems arise. The first problem concerns a possibility of the representation of a space В as a direct topologie sum of Im(7 — A) and Ker(7 — A). In Section 1 we give. a necessary and sufficient conditions of this representation for any linear operation in В (cf. [ 8], [9]). The second problem concerns the estimation of a norm of a minimal projection P. The answer is given in Section 2 with the help of the concave function g (which has no name for the present) and a Chebyshev radius, which were before used by the estimation of a norm of a minimal projection onto hyperspaces [ 6]. As the examples showing the obtained results we take the vector-valued Orlicz space B = LMl ([0, 1]; LM? (0, 1)), the Banach space with symmetric norm (in particular, /l5 c0) and the space C(S*) of the all continuous functions on the circle S1. Note that in the last two examples, our results can also be obtained in a more complicated way with the help of the theory of operators acting on compact topological groups (cf. for example [ 1 1 ], [ 12 ]).
Path Mapping Approach for Network Function Virtualization Resource Allocation with Network Function Decomposition Support

Recently, Network Function Virtualization (NFV) and Software Defined Networking (SDN) have attracted many mobile operators. For the flexible deployment of Network Functions (NFs) in an NFV environment, NF decompositions and control/user plane separation have been introduced in the literature. That is to map traditional functions into their corresponding Virtual Network Functions (VNFs). This mapping requires the NFV Resource Allocation (NFV-RA) for multi-path service graphs with a high number of virtual nodes and links, which is a complex NP-hard problem that inherited its complexity from the Virtual Network Embedding (VNE). This paper proposes a new path mapping approach to solving the NFV-RA problem for decomposed Network Service Chains (NSCs). The proposed solution has symmetrically considered optimizing an average embedding cost with an enhancement on average execution time. The proposed approach has been compared to two other existing schemes using 6 and 16 scenarios of short and long simulation runs, respectively. The impact of the number of nodes, links and paths of the service requests on the proposed scheme has been studied by solving more than 122,000 service requests. The proposed Integer Linear Programming (ILP) and heuristic schemes have reduced the execution time up to 39.58% and 6.42% compared to existing ILP and heuristic schemes, respectively. Moreover, the proposed schemes have also reduced the average embedding cost and increased the profit for the service providers.
Mathematical modelling and integration of complex biological data : analysis of the heterosis phenomenon in yeast

The general framework of this thesis is the issue of the genotype-phenotype relationship, through the analysis of the heterosis phenomenon in yeast, in an approach combining biology, mathematics and statistics. Prior to this work, a very large set of heterogeneous data, corresponding to different levels of organization (proteomics, fermentation and life history traits), had been collected on a semi-diallel design involving 11 strains belonging to two species. This type of data is ideally suited for multi-scale modelling and for testing models for predicting the variation of integrated phenotypes from protein and metabolic (flux) traits, taking into account dependence patterns between variables and between observations. I first decomposed, for each trait, the total genetic variance into variances of additive, inbreeding and heterosis effects, and showed that the distribution of these components made it possible to define well-defined groups of proteins in which most of the characters of fermentation and life history traits took place. Within these groups, the correlations between the variances of heterosis and inbreeding effects could be positive, negative or null, which was the first experimental demonstration of a possible decoupling between the two phenomena. The second part of the thesis consisted of interfacing quantitative proteomic data with the yeast genome-scale metabolic model using a constraint-based modelling approach. Using a recent algorithm, I looked, in the space of possible solutions, for the one that minimized the distance between the flux vector and the vector of the observed abundances of proteins. I was able to predict unobserved fluxes, and to compare correlation patterns at different integration levels. Data allowed to distinguish between two major types of fermentation or life history traits whose biochemical interpretation is consistent in terms of trade-off, and which had not been highlighted from quantitative proteomic data alone. Altogether, my thesis work allows a better understanding of the evolution of the genotype-phenotype map.
Generalized Director Approach for Liquid-Crystal-Based Reconfigurable RF Devices

This letter presents a closed-form integral-equation formulation that models the director tilting in nematic liquid crystals (LCs). The proposed formulation is computationally efficient compared to numerical methods and provides physical insight into the matter. Our previous work is generalized from the one-constant approach to all the possible cases that cover the elastic constants. These constants determine in great extent the electrical properties of the LC, and subsequently, the response of the reconfigurable devices that make use of it. Therefore, a more precise but still simple modeling of their influence is pursued here. Simulations show good agreement with numerical implementations. In comparison, the error in the estimation is considerably reduced when using the integral-equation formulation, especially as the polarization voltage or the dielectric anisotropy decreases.
Reduced posting and marking of flight progress strips for en route air traffic control : final report.

Flight progress strips (FPSs) are used by air traffic controllers to obtain information about a flight and to record changes in flight parameters such as route, speed and altitude. A new display system is being implemented in air traffic control centers that will allow controllers less room to post FPSs. This study examines the performance and workload effects of removing some of the redundant behaviors, such as posting and marking, associated with the FPS that are required for en route air traffic control by testing a new marking and posting procedure designed to reduce the controller's need for the FPS. Individual controllers and controller teams operating in either high- or low-altitude sectors participated in the study. Results showed that controllers posted fewer FPSs and marked them less often in the experimental procedure. No detrimental effects on performance, workload, position relief briefings, or team communications were observed. Most controllers reported that they preferred the experimental procedure and online measures of workload using the experimental procedure were comparable to the existing procedure.
Analysis of tip-gap size on tip-leakage flow in an axial fan at design and off-design operating conditions

Large-eddy simulations of the flow in a ducted axial fan are performed to investigate the dynamics of tip clearance flow for several tip-gap sizes at design and off-design operating conditions. The Navier-Stokes equations are solved on a multi-block structured 140-million-cell mesh in a rotating frame of reference for a single out of five blades with periodic boundary conditions in the circumferential direction and prescribed inflow conditions based on experimental data. The results show that increasing the tip-gap size results in various vortices in the tip-gap region, i.e., tip-leakage, separation, and induced vortices, which enlarge the diameter and the strength of the main tip vortex. For the off-design operating condition, the tip-gap vortex for the smallest tip-gap size decays faster than that for the design operating condition. For the largest tip clearance, spiral vortex breakdown occurs at the design operating condition.
Poloidal Rotation and Edge Ion Temperature Measurements Using Spectroscopy Diagnostic on Aditya-U Tokamak

The impurity ion poloidal rotation and ion temperature from the Aditya-U tokamak plasma have been measured using a high-resolution spectroscopic diagnostic. It comprises of a high resolution, 1 m, f/8.7, Czerny-Turner configuration spectrometer along with charge coupled device (CCD) detector. The system monitors the spectral line emission of C2+ impurity ions at 464.74 nm from the top port of the Aditya-U vacuum vessel with the lines of sight covering the plasma minor radius from r = 11.55 cm to 21.55 cm. The impurity ion poloidal rotation velocity and temperature have been estimated using the Doppler shift and Doppler broadening of the spectral lines respectively. The maximum poloidal rotation at a radial location of 21.55 cm in the edge of the plasma during the plasma current flat top was observed to be ~4 km/s for the analyzed discharges and the ion temperatures measured in the edge were in the range of 32–40 eV.
Improving the Quality Properties of Chicken Burger

The present study was undertaken to produce new low coast chicken burgers with significant nutritional value and to improve the physiochemical properties of the familiar chicken burger using partially replacement of breast chicken meat in formula 1 (F1), using 10% wheat germ and formula 2 (F2) with 30% pumpkin pulp, which were the most palatable ratios being win according to the panelists evaluations. The formulas were investigated for their physicochemical properties, consumer acceptability, approximate chemical composition, minerals content and the profile of amino and fatty acids. The results astonished that, the incorporation of wheat germ and pumpkin pulp made the products more palatable and increased both of crude fiber and carbohydrate content; further more wheat germ increased the crude fat in F1 and pumpkin pulp increased the moisture, ash, crude fiber and total carbohydrate contents significantly in F2. Sensory evaluation declared that there were no significant differences among the control sample and the two prepared formulas in all parameters, moreover adding wheat germ and pumpkin pulp improved the overall acceptability. It was astonishing that F2 was superior to control sample regarding to the organoleptic properties. Data obtained significant increase (P < 0.05) in both cooking loss and shrinkage in F2, otherwise cooking yield decreased significantly. The highest cooking yield (lowest cooking loss, shrinkage and expressible water) was recorded for F1. Adding wheat germ and pumpkin pulp resulted in slightly decreasing in the total essential amino acid content (1.76%, 2.09% respectively) compared to control sample. Wheat germ led to an increase in poly unsaturated fatty acids content (from 71.46 in control, to 74.25% in F1), whereas incorporating of pumpkin pulp into F2 decreased the % of saturated fatty acids while increased the total poly unsaturated fatty acids from 71.46 % in control to 73.74 % in F2. Moreover, using wheat germ and pumpkin pulp in our prepared chicken burgers reduced the final coasts by approximately 7.1 and 27% % respectively.

Charge calibration of DRZ scintillation phosphor screens

As a basic diagnostic tool, scintillation screens are employed in particle accelerators to detect charged particles. In extension to the recent revision on the calibration of scintillation screens commonly applied in the context of plasma acceleration [T. Kurz et al., Rev. Sci. Instrum. 89 (2018) 093303], here we present the charge calibration of three DRZ screens (Std, Plus, High), which promise to offer similar spatial resolution to other screen types whilst reaching higher conversion efficiencies. The calibration was performed at the Electron Linac for beams with high Brilliance and low Emittance (ELBE) at the Helmholtz-Zentrum Dresden-Rossendorf, which delivers picosecond-long beams of up to 40 MeV energy. Compared to the most sensitive screen, Kodak BioMAX MS, of the aforementioned recent investigation by Kurz et al., the sample with highest yield in this campaign, DRZ High, revealed a 30% increase in light yield. The detection threshold with these screens was found to be below 10 pC/mm2. For higher charge-densities (several nC/mm2) saturation effects were observed. In contrast to the recent reported work, the DRZ screens were more robust, demonstrating higher durability under the same high level of charge deposition.

SELECTION FOR GRAIN YIELD IN BREAD WHEAT UNDER NORMAL IRRIGATION AND DROUGHT STRESS CONDITIONS.

To improve grain yield/plant, two cycles of pedigree selection were achieved in a segregating population of wheat (Triticum aestivum L.) in the F 4 , F 5 and F 6 generations under normal and drought stressed environments. Significant differences (p<0.01) among the selected families for the selection criterion; grain yield/plant were observed in all the studied traits under the two environments in F4 and F6-generations. After two cycles of pedigree selection for grain yield/plant the values of gcv and pcv were decreased from F4 to F6-generation in all traits under both environments and were very close to each other, resulted in very high estimates of heritability in broad sense which calculated from the expected mean squares. The average direct gain in grain yield/plant was 90.20, 70.14 and 37.64, 52.46% from the bulk sample and the better parent under normal irrigation and drought stress; respectively. Under irrigation, the best five families, No.127, No.146, No.273, No.377 and No.452 outyielded the better parent Giza 168 by 38.87, 46.57, 42.63, 56.75 and 64.96%; respectively. The family No.452 was like Giza 186 in earliness. Under drought stress, selection for grain yield/plant delayed maturity by 8.59% from the better parent, but, not from the bulk sample. The best families in grain yield; No.202, No.296, No.379, No.389, No.395 and No.397 showed significant delay in maturity than the earlier parent. The best two families No. 92 and No.306 were early as the earlier parent Sisd4 and showed significant (p<0.01) grain yield/plant from the better parent Giza 168 of 26.46 and 59.72%; respectively. In the F6-generation under both environments all the traits which showed positive genotypic correlation with grain yield, days to heading, plant height, biological yield/plant and number of spikes/plant showed negative correlations with grain weight/spike, number of grains/spike, and 100-garin weight.
Avaliação do desempenho de wetlands horizontais subsuperficiais como pós-tratamento de efluentes de reatores UASB

Um sistema composto por um reator anaerobio do tipo UASB seguido de duas wetlands horizontais de fluxo subsuperficial construidas em paralelo foi avaliado para o tratamento de aguas residuarias geradas na cidade de Belo Horizonte, Brasil (50 habitantes para cada unidade). Uma unidade foi plantada com taboas (Typha latifolia) e a outra nao foi vegetada. Amostras do esgoto bruto, do efluente do reator UASB e do efluente das unidades de wetlands foram coletadas por um periodo de oito meses. O efluente final apresentou excelente qualidade em termos de materia orgânica e solidos suspensos, mas apresentou baixa capacidade de remocao de nutrientes. Valores medios de concentracao para as unidades plantadas e nao plantadas foram, respectivamente: DBO: 15 e 19 mg/L; DQO: 42 e 64 mg/L; SST: 3 e 5 mg/L; NT: 27 e 33 mg/L; N-NH3: 25 e 29 mg/L; P Total: 1.2 e 1.5 mg/L; Coliformes Totais: 9,0 x 105 e 2,0 x 106 NPM/100 mL; E. coli: 1,3 x 105 e 4,6 x 105 NPM/100 mL. A wetland plantada apresentou concentracoes efluentes e eficiencias de remocao significativamente (Wilcoxon matched-pairs test) melhores em relacao a unidade plantada para a maioria dos constituintes. O presente estudo mostrou que wetlands horizontais de fluxo subsuperficial construidas podem efetivamente tratar o efluente de reatores anaerobios, sendo capazes de atingir a maioria dos padroes de lancamento de materia orgânica e solidos suspensos.
Depth-sensing using AFM contact-resonance imaging and spectroscopy at the nanoscale

Subsurface metrology techniques are of significant importance at the nanoscale, for instance, for imaging buried defects in semiconductor devices and in intracellular structures. Recently, ultrasonic-based atomic force microscopy has attracted intense attention also for subsurface imaging. Despite many applications for measuring the real and imaginary part of the local surface modulus, the physical mechanism for subsurface imaging is not fully understood. This prevents accurate data interpretation and quantitative reconstruction of subsurface features and hinders the development of an optimized experimental and engineering setup. In this paper, we present quantitative depth-sensing of subsurface cavity structures using contact-resonance atomic force microscopy (CR-AFM) imaging and spectroscopy. Our results indicate that for imaging subsurface cavity structures using CR-AFM, the induced contact stiffness variations are the key contrast mechanism. The developed algorithm based on this mechanism allows one to precisely simulate the experimental image contrasts and give an accurate prediction of the detection depth. The results allow a better understanding of the imaging mechanism of ultrasonic-based AFM and pave the way for quantitative subsurface reconstruction.
Superfast Accurate Low Rank Approximation

Low Rank Approximation is among most fundamental subjects of numerical linear algebra having important applications to various areas of modern computing and %they range from machine learning theory and %neural networks to data mining and analysis. The known algorithms compute such approximations by using more flops than the input matrix has entries, but we prove that much fewer flops than entries are sufficient in the case of the average input ("flop" stands for "floating point arithmetic operation"). We prove this twice -- for the solutions by means of two distinct algorithms, and we analyze them by applying two different approaches. Our analysis of both algorithms is quite involved, but we devise them mostly by simplifying, combining, and ameliorating the known techniques, although we propose some technical novelties for further enhancing the performance of the popular Cross-Approximation Algorithms. They are highly efficient empirically, and we prove that they are efficient for the average input. We specify some narrow classes of hard inputs for which the presented algorithms fail with high probability even when we randomize them, but we narrow such classes further by means of preprocessing with new sparse and structured multipliers. The average complexity estimates do not cover many realistic input classes, but our formal analysis is in good accordance with the results of our tests applied to benchmark inputs from discretized PDEs and Integral quations and to random inputs. Our work should already be of practical value but also leads to research challenges. At the end we list some of them, propose two novel extensions of our progress -- to the acceleration of the Fast Multipole Method and Conjugate Gradient algorithms, and explore and slightly extend the recent techniques of Osinsky, which enhance the output accuracy of CUR Approximation.
