description: The conventional wisdom for the formation of the first hard binary in core collapse is that three-body interactions of single stars form many soft binaries, most of which are quickly destroyed, but eventually one of them survives. We report on direct N-body simulations to test these ideas, for the first time. We find that both assumptions are often incorrect: 1) quite a few three-body interactions produce a hard binary from scratch; 2) and in many cases there are more than three bodies directly and simultaneously involved in the production of the first binary. The main reason for the discrepancies is that the core of a star cluster, at the first deep collapse, contains typically only five or so stars. Therefore, the homogeneous background assumption, which still would be reasonable for, say, 25 stars, utterly breaks down. There have been some speculations in this direction, but we demonstrate this result here explicitly, for the first time.

description: As one of the oldest shaping manufacturing processes, forging and especially hot forging is characterized by extreme loads on the tool. The thermal load in particular is able to cause constant changes in the hardness of the surface layer, which in turn has a decisive influence on the numerical estimation of wear. Thus, also during numerical wear, modeling hardness changes need to be taken into account. Within the scope of this paper, a new implementation of a numerical wear model is presented, which, in addition to dynamic hardness models for the base material, can also take into account the properties of a nitride wear protection layer as a function of the wear depth. After a functional representation, the new model is applied to the wear calculation of a multi-stage industrial hot forging process. The applicability of the new implementation is validated by the evaluation of the occurring hardness, wear depths and the locally associated removal of the wear protection layer. Consecutively, a tool life calculation module based on the calculated wear depth is implemented and demonstrated. In general, a good agreement of the results is achieved, making the model suitable for detailed 2D as well as large 3D Finite Element calculations.

description: This report describes the analyses associated with the discard estimation of 14 federally managed fish and invertebrate species groups during the July 2014 through June 2015 time period and the expected coverage needed by at-sea observers for northeastern US fisheries for the April 2016 through March 2017 period using the Standardized Bycatch Reporting Methodology. An estimated 57,063 mt (125,803,405 lb) of federally regulated species were discarded during the July 2014 through June 2015 time period. The predominant species groups discarded were skates (Rajidae) and spiny dogfish (Squalus acanthias). Across all species groups examined, "No Market" was the reason reported for the majority of discards. Analyses also revealed that for fleets with observer coverage, the coverage within a fleet corresponded with the spatial and temporal patterns of fishing activity in terms of kept weight of all species. The discards reported in this document may not necessarily correspond directly with the discard estimates derived for individual stock assessments because of differences in stratification and data. Hence, the discard estimates are not definitive, but indicative of where discarding occurred among commercial fleets and for which species groups. The sea days needed to achieve a precision-based performance standard (30% coefficient of variation of the discard estimate) were estimated to be 10,746 sea days for the 14 fish and invertebrate species groups across 57 fleets. The sea day analyses used a standardized protocol to account for the importance of the discarded species relative to the amount of discards by each fleet and total fishing mortality.

description: Despite the successes of the standard model, the non-perturbative dynamics of the strong interaction are not fully understood yet. Charmonium spectroscopy serves as an ideal tool to shed light on the dynamics of the strong interaction such as quark confinement and the generation of hadron masses. The BESIII collaboration studies extensively the strong interaction and various aspects that could shed light on physics beyond the standard model via copious e$^+$e$^-$ collisions at the BESIII/BEPCII facility in Beijing, China, in the charmonium mass regime. We present a few of the recent results with the emphasis on charmonium spectroscopy studies using 106$\times10^6$ $ψ^\prime$ events.

description: Vehicle-to-everything (V2X) communication is seen as one of the main enabling technol-ogies for automated vehicles. Collective perception is especially promising, as it allows connected traffic participants to “see through the eyes of others” by sharing sensor-detected objects via V2X communication. Its benefit is typically assessed in terms of the increased object update rate, redun-dancy, and awareness. To determine the safety improvement thanks to collective perception, the authors introduce new metrics, which quantify the environmental risk awareness of the traffic par-ticipants. The performance of the V2X service is then analyzed with the help of the test platform TEPLITS, using real traffic traces from German highways, amounting to over 100 h of total driving time. The results in the considered scenarios clearly show that collective perception not only con-tributes to the accuracy and integrity of the vehicles’ environmental perception, but also that a V2X market penetration of at least 25% is necessary to increase traffic safety from a “risk of serious traffic accidents” to a “residual hypothetical risk of collisions without minor injuries” for traffic participants equipped with non-redundant 360° sensor systems. These results support the ongoing world-wide standardization efforts of the collective perception service.

description: We demonstrate a novel, to the best of our knowledge, concept for an all-optical switch based on the optical Kerr effect in optical interference coatings. The utilization of the internal intensity enhancement in thin film coatings as well as the integration of highly nonlinear materials enable a novel approach for self-induced optical switching. The paper gives insight into the design of the layer stack, suitable materials, and the characterization of the switching behavior of the manufactured components. A modulation depth of 30% could be achieved, which prepares the way for later applications in mode locking.

description: The recently discovered gamma-ray binary 1FGL J1018.6-5856 has a proposed optical/near-infrared (OIR) counterpart 2MASS 10185560-5856459. We present Stromgren photometry of this star to investigate its photometric variability and measure the reddening and distance to the system. We find that the gamma-ray binary has E(B-V) = 1.34 +/- 0.04 and d = 5.4^+4.6_-2.1 kpc. While E(B-V) is consistent with X-ray observations of the neutral hydrogen column density, the distance is somewhat closer than some previous authors have suggested.

The sacrificial layer is cost efficient and environmentally friendly and can be dissolved using only water. We demonstrate an improved performance compared to filters on thin polymer layers from the same coating run. With these filters, a single-element coarse wavelength division multiplexing transmitting device for telecommunication applications can be realized by inserting the filter between fiber ends.

description: We consider the propagation of classical and non-classical light in multi-mode optical waveguides. We focus on the evolution of the few-photon correlation functions, which, much like the light-intensity distribution in such systems, evolve in a periodic manner, culminating in the 'revival' of the initial correlation pattern at the end of each period. It is found that when the input state possesses non trivial symmetries, the correlation revival period can be longer than that of the intensity, and thus the same intensity pattern can display different correlation patterns. We experimentally demonstrate this effect for classical, pseudo-thermal light, and compare the results with the predictions for non-classical, quantum light.

Seine Geschichten legen eingangs den Sachverhalt in literarisch gestalteter Form dar und entfalten das folgende Prozessgeschehen unter Verwendung von Anklageschriften, Gutachten und anwaltlichen Plädoyers narrativ. Durch die Vielzahl der Stimmen, Perspektiven und integrierten Textsorten sind Pitavalgeschichten ausgesprochen hybrid und können einen beachtlichen Umfang erreichen. Hier wird neben der Entstehungsgeschichte, gattungstypischen Merkmalen und der Rezeption von Pitavalgeschichten insbesondere auf das Verhältnis von Fakt und Fiktion und auf die Abgrenzung von der literarischen Rechtsfallgeschichte eingegangen.
description: A Pitaval story is a trial or legal case narrative where neither the offence nor the perpetrator but the lawyers and their pleas are at the centre. The name derives from the author of the first French collection of "Causes célèbres et intéressantes avec les jugemens qui les ont décidées", François Gayot de Pitaval. His stories set out the circumstances of the case in literary form to begin with and then narratively unfold the happenings in court based on indictments, reports and legal pleas. Because of their multitude of voices, perspectives and integrated text forms, Pitaval stories are exceptionally hybrid and can reach a considerable extent. This article, in addition to the genesis, genre specific features and the reception of Pitavals, discusses in particular the relation between fact and fiction and the delimitation from other genres of literary legal case narratives.

description: This paper presents numerical modeling and experimental validation of the signal path loss at the 5.8 GHz Industrial, Scientific, and Medical (ISM) band, performed in the context of fat-intrabody communication (fat-IBC), a novel intrabody communication platform using the body-omnipresent fat tissue as the key wave-guiding medium. Such work extends our previous works at 2.0 and 2.4 GHz in the characterization of its performance in other useful frequency range. In addition, this paper also includes studies of both static and dynamic human body movements. In order to provide with a more comprehensive characterization of the communication performance at this frequency, this work focuses on investigating the path loss at different configurations of fat tissue thickness, antenna polarizations, and locations in the fat channel. We bring more realism to the experimental validation by using excised tissues from porcine cadaver as both their fat and muscle tissues have electromagnetic characteristics similar to those of human with respect to current state-of-art artificial phantom models. Moreover, for favorable signal excitation and reception in the fat-IBC model, we used topology optimized waveguide probes. These probes provide an almost flat response in the frequency range from 3.2 to 7.1 GHz which is higher than previous probes and improve the evaluation of the performance of the fat-IBC model. We also discuss various aspects of real-world scenarios by examining different models, particularly homogeneous multilayered skin, fat, and muscle tissue. To study the effect of dynamic body movements, we examine the impact of misalignment, both in space and in wave polarization, between implanted nodes. We show in particular that the use of fat-IBC techniques can be extended up in frequency to a broadband channel at 5.8 GHz.

description: The use of Space-Time Block Codes (STBCs) increases significantly the optimal detection complexity at the receiver unless the low-complexity decodability property is taken into consideration in the STBC design. In this paper we propose a new low-complexity decodable rate-5/4 full-diversity 4 x 4 STBC. We provide an analytical proof that the proposed code has the Non-Vanishing-Determinant (NVD) property, a property that can be exploited through the use of adaptive modulation which changes the transmission rate according to the wireless channel quality. We compare the proposed code to the best existing low-complexity decodable rate-5/4 full-diversity 4 x 4 STBC in terms of performance over quasi-static Rayleigh fading channels, worst- case complexity, average complexity, and Peak-to-Average Power Ratio (PAPR). Our code is found to provide better performance, lower average decoding complexity, and lower PAPR at the expense of a slight increase in worst-case decoding complexity.

description: The ground state spin of the negatively charged nitrogen-vacancy center in diamond has been the platform for the recent rapid expansion of new frontiers in quantum metrology and solid state quantum information processing. In ambient conditions, the spin has been demonstrated to be a high precision magnetic and electric field sensor as well as a solid state qubit capable of coupling with nearby nuclear and electronic spins. However, in spite of its many outstanding demonstrations, the theory of the spin has not yet been fully developed and there does not currently exist thorough explanations for many of its properties, such as the anisotropy of the electron g-factor and the existence of Stark effects and strain splittings. In this work, the theory of the ground state spin is fully developed for the first time using the molecular orbital theory of the center in order to provide detailed explanations for the spin's fine and hyperfine structures and its interactions with electric, magnetic and strain fields.

Conduction required for the study is provided by illumination of the surface. Application of illumination removes completely the band bending near the surface and restores initial population of the surface states. Our results indicate the existence of the energy gap 2Δ = 40 \pm 10 meV in intrinsically-populated Si(111)-7x7 surface.

description: The primary purpose of this investigation was to explore the effects of variable doses of home practice Vocal Function Exercises (VFEs) on attainment of pre-established maximum phonation time (MPT) goals in individuals between the ages of 18 and 25 with normal voice. A secondary purpose was to monitor for potentially toxic effects of high doses of VFEs. Three experimental groups completed a six-week VFE protocol and practiced twice daily. The low dose group performed each exercise once, the traditional group twice, and the high dose group four times. Results indicated significant change in VFE MPT for all three groups and higher goal attainment in the high dose group. Low doses appear insufficient to produce substantial change in voice production. Acoustic MPT improved most in the traditional dosage group, which also exhibited best maintenance and best overall outcomes. No toxic effects in vocal fold condition or phonation were observed or measured secondary to high VFE exposure.
Helicity Asymmetry in gamma p -> pi+ n with FROST

description: The main objective of the FROST experiment at Jefferson Lab is the study of baryon resonances. The polarization observable E for the reaction gamma p to pi+n has been measured as part of this program. A circularly polarized tagged photon beam with energies from 0.35 to 2.35 GeV was incident on a longitudinally polarized frozen-spin butanol target. The final-state pions were detected with the CEBAF Large Acceptance Spectrometer. Preliminary polarization data agree fairly well with present SAID and MAID partial-wave analyses at low photon energies. In most of the covered energy range, however, significant deviations are observed. These discrepancies underline the crucial importance of polarization observables to further constrain these analyses.

description: This report provides insight in the planned enabling solutions to be developed within HYPERRIDE project. The infrastructure requirements, demonstration site descriptions and definition of Key Performance Indicators (KPI) outlined here have to be read in context with the connected deliverables D2.2 and D2.3. Based on the availability of Direct Current (DC) based renewable energy resources and power electronics converters it is a possible development to evolve from currently used Alternating Current (AC) technologies to DC grid systems. Some of the benefits are: improved grid resiliency decreased cost and increased energy efficiency on system level facilitated integration of renewable energy sources and DC based loads increased transmission capacity reduced voltage fluctuations reduced control and synchronisation effort environmental benefits Throughout the last decade, DC systems have been demonstrated for various use cases and rising number of pilot installations all over the world. In the report a description of the most no table installations can be found. A majority of theses demonstrators have been established in Asia. With the analysis of these instalments was possible to identify potential gaps for new infrastructures from interoperability demands in Information and Communications Technology (ICT) solutions, means of failure mitigation and prevention, mechanisms of safety such as breakers etc. The solutions in HYPERRIDE as described in D2.3 will be demonstrated in the pilot sites in Germany, Switzerland and Italy as described in the report. To provide a toolbox for the analysis of the individual infrastructures a set of KPIs have been defined based on the methodology to evolve from available AC definitions proven to be beneficial and adapt those, if applicable, to DC grid infrastructures. In case a gap has been identified new definitions are proposed.

description: Bibliography: p. 117-123.
description: The Gothic novel manipulates several stock devices to create an atmosphere of horror, fear, dread and awe. These devices include various agents of terror, (ghosts, graveyards, castles and disembodied voices, for example), as well as a specific focus upon what is suspenseful, fantastic and horrifying in an essentially contrived confrontation between good and evil. Violence and evil are external threats in the Gothic novel; aspects of the environment. Character development is basically unimportant and the emphasis in the presentation of characters is upon their reaction to the same horrifying plot which is intended to excite and terrify the reader. The limited character development, simple plot and predictable conventions which characterized the Gothic novel combined to ensure these novels short-lived popularity and, subsequently, generally facetious critical treatment. While the limitations of the form and the crudities of the Gothic setting are undeniable, I feel that the Gothic novel provided later writers with a set of symbols with which to amplify horror, fear and dread. As the novel matured as a form, and character development became more focal, these emotions were given a psychological, internal origin and the horrors of self-confrontation and alienation became essential conflicts dealt with in characterization. The Gothic novel contributed a rich and accessible collection of images for the presentation of these conflicts and an external and, therefore, tangible, expression of elusive and undefinable anxieties. My purpose in this thesis is to discuss the influence of the Gothic novel on later novelists by defining the use of Gothic conventions in selected novels of Charlotte and Emily Bronte. Jane Eyre, Wuthering Heights and Villette are novels about women coming to terms with their own personalities and the relationship between the personality and its environment. In these novels, the use of Gothic conventions at moments of intense emotional crisis emphasizes the horror inherent in self-discovery and, in a larger sense, the horror of life. I will discuss both the moments of crisis in the novels and the Gothic conventions which emphasize them in order to demonstrate the powerful emotional contribution made by Gothic imagery.

description: The radial and tangential force components acting on each sub-conductor of a Roebel bar in a large generator lead to mechanical vibration of the stator bars in the slot. This double-frequency vibration results in additional mechanical stress on fixation materials in the slot and causes insulation deterioration and looseness of stator bars. Particularly during short circuits, the stator bars are subjected to immense radial forces. Understanding the origin of these vibrations and developing models to anticipate them is essential to increase the reliability and expected life time of large generators. This paper presents an analytical method for the estimation of Roebel bar forces during symmetrical and asymmetrical short circuits. For this purpose, an analytical calculation method is developed to estimate the transient three-phase currents during different short circuits. These currents induce tangential and radial flux density components along the slot width and length, respectively. An analytical approach is introduced to estimate these flux densities as a function of the slot length. Subsequently, an analytical method for calculating the Roebel bar forces considering three-dimensional transpositions is developed and verified with finite element calculations. Beyond the state of the art, the impact of the rotor field on the radial and tangential components of the stray fluxes are analytically estimated. The result is a comprehensive analytical tool for the estimation of Roebel bar forces during different short circuits in large generators.

description: The Tianjin coastal region in Bohai Bay, Northern China, is increasingly affected by storm-surge flooding which is exacerbated by anthropogenic land subsidence and global sea-level rise (SLR). We use a combination of synthetic aperture radar interferometry (InSAR), continuous GPS (CGPS), and tide-gauge observations to evaluate the spatial variability of relative SLR (RSLR) along the coastline of Tianjin. Land motion obtained by integration of 2 tracks of Sentinel-1 SAR images and 19 CGPS stations shows that the recent land subsidence in Tianjin downtown is less than 8 mm/yr, which has significantly decreased with respect to the last 50 years (up to 110 mm/yr in the 1980s). This might benefit from the South-to-North Water Transfer Project which has provided more than 1.8 billion cubic meters of water for Tianjin city since 2014 and reduced groundwater consumption. However, subsidence centers have shifted to suburbs, especially along the coastline dominated by reclaimed harbors and aquaculture industry, with localized subsidence up to 170 mm/yr. Combining InSAR observations with sea level records from tide-gauge stations reveals spatial variability of RSLR along the coastline. We find that, in the aquaculture zones along the coastline, the rates of land subsidence are as high as 82 mm/yr due to groundwater extraction for fisheries, which subsequently cause local sea levels to rise nearly 30 times faster than the global average. New insights into land subsidence and local SLR could help the country's regulators to make decisions on ensuring the sustainable development of the coastal aquaculture industry.

description: We present evidence that there is an M dwarf problem similar to the previously identified G dwarf and K dwarf problems: the number of low-metallicity M dwarfs is not sufficient to match simple closed-box models of local Galactic chemical evolution. We estimated the metallicity of 4141 M dwarf stars with spectra from the Sloan Digital Sky Survey (SDSS) using a molecular band strength versus metallicity calibration developed using high resolution spectra of nearby M dwarfs. Using a sample of M dwarfs with measured magnitudes, parallaxes, and metallicities, we derived a relation that describes the absolute magnitude variation as a function of metallicity. When we examined the metallicity distribution of SDSS stars, after correcting for the different volumes sampled by the magnitude-limited survey, we found that there is an M dwarf problem, with the number of M dwarfs at [Fe/H] ~ -0.5 less than 1% the number at [Fe/H] = 0, where a simple model of Galactic chemical evolution predicts a more gradual drop in star numbers with decreasing metallicity.

description: Let S be a complex smooth projective surface and L be a line bundle on S. For any given collection of isolated topological or analytic singularity types, we show the number of curves in the linear system |L| with prescribed singularities is a universal polynomial of Chern numbers of L and S, assuming L is sufficiently ample. Moreover, we define a generating series whose coefficients are these universal polynomials and discuss its properties. This work is a generalization of Gottsche's conjecture to curves with higher singularities.

When a dream turns into a nightmare: Due to negative dream content or to negative appraisal?

description: Nightmares are a well-known phenomenon. The content of aversive dreams seems to be ubiquitous in dreams. Nevertheless, a dream containing aversive contents does not necessarily have to be a nightmare. We hypothesize that nightmares are rather caused by a more negative appraisal of the contents of aversive dreams than by the dream content itself. To investigate this question, N = 99 participants kept dream diaries over 28 consecutive days. An experimental group included persons with frequent nightmares and a control group of persons without nightmares. Violent dream content and emotions during the dream were analyzed by the dreamers themselves and as well as by four external raters. Regarding violent dream content in non-nightmare dream reports, the external raters usually agreed with the dreamers’ ratings. However, there was significant disagreement regarding the nightmare reports. Furthermore, external raters significantly rated the dreams as less positive than the dreamers did, and external raters rated the nightmare reports as more negative than the dreamers themselves did. Taken together, the results support the hypothesis that the classification of a dream as a nightmare does not only depend on its content but also on other factors. This suggests that the dreamers’ ratings of a dream as a nightmare are based on more factors than dream content.

Investigation Of The Mechanism And Technical Implementation Of Acoustic Thermography
Creators: name: Homma, Christian
Publisher: name: Zenodo
Year: 2016
Subjects: Thermography

description: In this thesis project, a newly developed 3D laser vibrometer system was used

to demonstrate that heating of the defect-free bulk correlates with local stresses in the material and is caused by damping of the ultrasound. Two additional mechanisms that lead to crack heating were identi ed as friction and plastic deformation.

The measured quadratic relationship between heating and local displacements in the specimen is explained by an additional modulation of the normal force pressing the crack faces together. Due to the small displacements in the parts, it is necessary to postulate a mechanism strongly dominated by static rather than dynamic friction. Plastic deformation was only observed in extreme cases. Although local stress concentration occurs at crack tips, crack tip blunting as well as crack closure ordinarily prevent plastic deformation and crack growth. For the technical implementation, commonly used systems based on ultrasonic welding equipment were investigated and their disadvantages|especially with regard to reproducibility|were demonstrated and explained. Based on these results, a new technique was developed, which uses a tunable exciter to account for the individual eigenfrequencies of the specimen and to achieve resonant excitation of the specimen and to achieve a resonant excitation of the specimen. This also enabled increased eciency as a lower-power piezoelectric exciter is sucient to achieve the same displacements of the specimen./p>

p>br />
Finally, necessary aspects for a technical implementation were investigated. Of particular interest are methods to characterize and verify the non-destructive nature of the procedure. Detection limits, post-processing methods for the infrared data, causes for false indications and a comparison with conventional NDT methods are also discussed./p>

Comet 22P/Kopff: Dust environment and grain ejection anisotropy from visible and infrared observations

description: We present optical observations and Monte Carlo models of the dust coma, tail, and trail structures of comet 22P/Kopff during the 2002 and 2009 apparitions. Dust loss rates, ejection velocities, and power-law size distribution functions are derived as functions of the heliocentric distance using pre- and post-perihelion imaging observations during both apparitions. The 2009 post-perihelion images can be accurately fitted by an isotropic ejection model. On the other hand, strong dust ejection anisotropies are required to fit the near-coma regions at large heliocentric distances (both inbound at $r_h$=2.5 AU and outbound at $r_h$=2.6 AU) for the 2002 apparition. These asymmetries are compatible with a scenario where dust ejection is mostly seasonally-driven, coming mainly from regions near subsolar latitudes at far heliocentric distances inbound and outbound. At intermediate to near-perihelion heliocentric distances, the outgassing would affect much more extended latitude regions, the emission becoming almost isotropic near perihelion. We derived a maximum dust production rate of 260 kg s$^{-1}$ at perihelion, and an averaged production rate over one orbit of 40 kg s$^{-1}$. An enhanced emission rate, accompanied also by a large ejection velocity, is predicted at $r_h>$2.5 pre-perihelion. The model has also been extended to the thermal infrared in order to be applied to available trail observations with IRAS and ISO spacecrafts of this comet. The modeled trail intensities are in good agreement with those observations, which is remarkable taking into account that those data are sensitive to dust ejection patterns corresponding to several orbits before the 2002 and 2009 apparitions.

description: In dieser Arbeit wurde mit einem dafür neu entwickelten 3D-Laservibrometermesssystem gezeigt, dass die Erwärmung des rissfreien Bulk mit der lokalen Spannung im Material korreliert und durch die Dämpfung des Ultraschalls (innere Reibung) hervorgerufen wird. Für die Erwärmung von Rissen wurden neben der Dämpfung Reibung sowie plastische Verformung identifiziert. Die gemessene quadratische Abhängigkeit der Erwärmung von der lokalen Auslenkung des Prüfteils l#sst sich im Bild der Reibung durch die zusätzliche Modulation der Normalkraft, die die Rissflanken aneinanderpresst, beschreiben. Wegen der kleinen Auslenkungen in den Bauteilen ist es notwendig, nicht von einem reinen Gleitreibungsfall, sondern vielmehr von einem stark von Haftreibung dominierten Modus auszugehen. Plastische Verformung wurde nur im Extremfall beobachtet. Zwar tritt an Rissspitzen eine lokale Spannungsüberhöhung auf, Rissspitzenverrundung und Rissschließen verhindern jedoch meist plastische Verformung und Risswachstum. Für die technische Umsetzung wurden die allgemein verwendeten Systeme auf Basis von Ultraschallschweißanlagen genauer untersucht und deren Unzulänglichkeiten – insbesondere hinsichtlich der Reproduzierbarkeit – aufgezeigt und begründet. Auf diesen Ergebnissen aufbauend wurde eine neue Technik entwickelt, die durch einen abstimmbare Erreger erlaubt, die Lage der individuellen Eigenfrequenzen zu berücksichtigen

und das Prüfteil resonant anzuregen. Auf diese Weise ließ sich außerdem die Effizienz steigern, da zum Erreichen derselben Auslenkungen des Prüfteils ein

Piezoerreger mit geringerer Leistung genügt. Schließlich wurden für eine technische Umsetzung notwendige Aspekte untersucht. Dazu gehören vor allem Methoden, die nicht automatisch gegebene Zerstörungsfreiheit zu charakterisieren und sicherzustellen. Daneben werden die Nachweisgrenzen,

Techniken zur Aufbereitung der Infrarotdaten, die Gründe für das Auftreten

von Fehlanzeigen sowie der Vergleich mit herkömmlichen ZfP-Methoden diskutiert.
