description: Usually, important parameters of young, low-mass star clusters are very difficult to obtain by means of photometry, especially when differential reddening and/or binaries occur in large amounts. We present a semi-analytical approach that, applied to the Hess diagram of a young star cluster, is able to retrieve the values of mass, age, star-formation spread, distance modulus, foreground and differential reddening, and binary fraction. The global optimisation method known as adaptive simulated annealing (ASA) is used to minimise the residuals between the observed and simulated Hess diagrams of a star cluster. The simulations are realistic and take the most relevant parameters of young clusters into account. Important features of the simulations are: a normal (Gaussian) differential reddening distribution, a time-decreasing star-formation rate, the unresolved binaries, and the smearing effect produced by photometric uncertainties on Hess diagrams. Free parameters are: cluster mass, age, distance modulus, star-formation spread, foreground and differential reddening, and binary fraction.

description: A number of assertions have been made regarding the inadequacy and ineffectiveness of social service agencies in the delivery of services to the increasing number of migrant Indians. Little documen­tation is available on the accuracy of these assertions. This study was designed in an attempt to fill information gaps by providing descriptive data on agency perceptions of social services available to treaty Inrlians residing in Calgary. In developing a theoretical framework for examining social services for migrant Indians, the author refers to criteria for assessment defined in terms of accessibility, suitability, adequacy, co-ordination, effectiveness and worker appropriateness. Primary attention is given to the availability and utilization of services, policies, procedures and attitudes regarding service needs of the Indian community. Three sample groups were chosen from the AID Directory, a list of 216 service organizations in Calgary. The 30 agencies included 7 Nati· ?? organizations; 7 frequently-used, non-Native agencies; and 16 non-Native agencies used very little or not at all by Indians. Four interviewers completed semi-structured interviews with representatives of the 30 agencies. The interview guide was designed by the researcher in consultation with several experts in the field of social welfare and with members of the Indian community. The instrument follows five topic headings: interviewer self-completion defining accessibility and suitability; programs; policies; procedures; and attitudes regarding service needs of treaty Indians. Results are reported according to these headings.

description: We present a probabilistic model for natural images which is based on Gaussian scale mixtures and a simple multiscale representation. In contrast to the dominant approach to modeling whole images focusing on Markov random fields, we formulate our model in terms of a directed graphical model. We show that it is able to generate images with interesting higher-order correlations when trained on natural images or samples from an occlusion based model. More importantly, the directed model enables us to perform a principled evaluation. While it is easy to generate visually appealing images, we demonstrate that our model also yields the best performance reported to date when evaluated with respect to the cross-entropy rate, a measure tightly linked to the average log-likelihood.

description: Weak gravitational lensing of distant galaxies provides a powerful probe of dark energy. The aim of this study is to investigate the application of convolutional neural networks (CNNs) to precision shear estimation. In particular, using a shallow CNN, we explore the impact of point spread function (PSF) misestimation and `galaxy population bias' (including `distribution bias' and `morphology bias'), focusing on the accuracy requirements of next generation surveys. We simulate a population of noisy disk and elliptical galaxies and adopt a PSF that is representative of a Euclid-like survey. We quantify the accuracy achieved by the CNN assuming a linear relationship between the estimated and true shears and measure the multiplicative ($m$) and additive ($c$) biases. We make use of an unconventional loss function to mitigate the effects of noise bias and measure $m$ and $c$ when we use either: (i) an incorrect galaxy ellipticity distribution or size-magnitude relation, or the wrong ratio of morphological types, to describe the population of galaxies (distribution bias); (ii) an incorrect galaxy light profile (morphology bias); or (iii) a PSF with size or ellipticity offset from its true value (PSF misestimation). We compare our results to the Euclid requirements on the knowledge of the PSF model shape and size. Finally, we outline further work to build on the promising potential of CNNs in precision shear estimation.

description: This paper proposes a method to vibration analysis in order to on-line monitoring of milling process quality. Adapting envelope analysis to characterize the milling tool materials is an important contribution to the qualitative and quantitative characterization of milling capacity and a step by modeling the three-dimensional cutting process. An experimental protocol was designed and developed for the acquisition, processing and analyzing three-dimensional signal. The vibration envelope analysis is proposed to detect the cutting capacity of the tool with the optimization application of cutting parameters. The research is focused on FFT Fourier transform optimization of vibration analysis and vibration envelope to evaluate the dynamic behavior of the machine/ tool/workpiece
Self-exciting hurdle models for terrorist activity

Subjects: subject: Applications (stat.AP)
subject: FOS: Computer and information sciences

description: A predictive model of terrorist activity is developed by examining the daily number of terrorist attacks in Indonesia from 1994 through 2007. The dynamic model employs a shot noise process to explain the self-exciting nature of the terrorist activities. This estimates the probability of future attacks as a function of the times since the past attacks. In addition, the excess of nonattack days coupled with the presence of multiple coordinated attacks on the same day compelled the use of hurdle models to jointly model the probability of an attack day and corresponding number of attacks. A power law distribution with a shot noise driven parameter best modeled the number of attacks on an attack day. Interpretation of the model parameters is discussed and predictive performance of the models is evaluated.

Domain knowledge representation in information systems
Creators: name: Rubin, Eran
Publisher: name: University of British Columbia
Year: 2009

description: Information Systems and software embed knowledge about the domain in which they operate. This knowledge can be very useful to various stakeholders in the organization, including developers, users, and other organizational workers. However, it is not readily accessible and usually intertwined with implementation details. Making this knowledge available would be beneficial for several reasons. In particular: 1) software often needs to be updated to reflect changes in the organization; this causes the embedded knowledge to stay current; 2) the actual system development process often incorporates the use of methods and techniques to properly record domain knowledge; 3) knowledge embedded in software is already available in a digital format; and 4) the tools typically used to manage system development (e.g. source and version controls) can be effective in management and control of knowledge. However, despite all these potential advantages, embedded knowledge is usually not readily accessible to knowledge seekers in the organization. This situation impedes the possible utilization of software-embedded knowledge. The objective of this dissertation is to develop ways of making software-embedded domain knowledge available, accessible, and usable to organizational users. The research challenge is to identify what domain knowledge is involved in systems development, to find ways to formalize it, and to demonstrate that it can be explicitly represented in developed systems. The research covers three main aspects: 1) identifying and formalizing embedded domain knowledge obtained in systems development processes; 2) developing methods for representing this knowledge formally to facilitate its use during and after system development and, 3) demonstrate how this knowledge can be explicitly represented in the final IS implementation code. The first aspect, namely the nature of embedded knowledge, is addressed by analyzing the requirements engineering, systems analysis, and enterprise modeling literature in order to identify the main constructs used for domain representation. Formalization is then accomplished using ontological analysis. The feasibility of explicit representation is attained by suggesting a Model Driven Architectures (MDA) where the formalized knowledge is used to drive processing in the system. Usability and usefulness of the ideas are demonstrated in two ways. First, case studies and examples show how domain knowledge acquired during extant methods of systems analysis can be represented using the proposed representation constructs. Second, a sample system design, supporting explicit domain knowledge representation in system code, is proposed and demonstrated via a simple prototype.

description: The diffractive heavy quark cross sections are estimated considering photon-Pomeron ($γ\pom$) interactions in hadron - hadron at RHIC, Tevatron, and CERN LHC energies. We assume the validity of the hard diffractive factorization and calculate the charm and bottom total cross sections and rapidity distributions using the diffractive parton distribution functions of the Pomeron obtained by the H1 Collaboration at DESY-HERA. Moreover, we compare our predictions with those obtained using the dipole model. We verify that this process is a good test of the different mechanisms for diffractive heavy quark production at hadron - hadron colliders.

description: Research in quantitative evolutionary genomics and systems biology led to the discovery of several universal regularities connecting genomic and molecular phenomic variables. These universals include the log-normal distribution of the evolutionary rates of orthologous genes; the power law-like distributions of paralogous family size and node degree in various biological networks; the negative correlation between a gene's sequence evolution rate and expression level; and differential scaling of functional classes of genes with genome size. The universals of genome evolution can be accounted for by simple mathematical models similar to those used in statistical physics, such as the birth-death-innovation model. These models do not explicitly incorporate selection, therefore the observed universal regularities do not appear to be shaped by selection but rather are emergent properties of gene ensembles. Although a complete physical theory of evolutionary biology is inconceivable, the universals of genome evolution might qualify as 'laws of evolutionary genomics' in the same sense 'law' is understood in modern physics.

The role of tyrosine phosphorylated caveolin-1 in regulating focal adhesion dynamics and cancer cell migration
Creators: name: Strugnell, Scott Stuart
Publisher: name: University of British Columbia
Year: 2009

description: Caveolin-1 (Cav1) is a conditional tumor suppressor whose expression is associated with a poor prognosis for many human cancer types. Cavi is a Src kinase substrate phosphorylated on tyrosine-14 (pYl4Cavl) that interacts with integrin and has been localized to focal adhesions (FAs). We undertook to study the role of pYl4Cavl in FA dynamics and tumor cell migration. Using FRAP analysis, we showed that pYl4Cavl phosphorylation and stabilization of FA kinase (FAK)-GFP in FAs occurs via a process that requires Rho/ROCK and Src signalling. In Cavi expressing MDA-231 breast carcinoma cells, pYl4Cavl was enriched in purified pseudopodial fractions while in low Cav1-expressing MDA-435 tumor cells, transfected Cav1, but not the Y1 4F mutant of Cay 1 -mRFP, was recruited to actin-rich protrusions. In MDA-435 tumor cells, transfected Cav1 and the phosphomimetic Cav1 mutant, Cav1Y14D, were found in close proximity to FA-associated proteins. The recruitment of either Cavl or Cav1Y14D to FAs was associated with increased cell migration. The positively charged Cav1Y14R mutant was not as closly associated with FA associated proteins, and increased cell spreading and stress fiber formation. The spatial association of pYl4Cavl with FAs may therefore regulate FA signaling and dynamics. The Mgat5 gene encodes the Golgi N-acetylglucosaminyltransferase-V that generates B1,6 branched N-glycans that bind galectin-3 at the cell surface forming a lattice domain. We found that the Mgat5/galectin lattice acts together with pYl4Cavl to stabilize FAK in FAs, thereby enhancing FA disassembly and de novo formation leading to the activation of directional tumor cell migration. Our data therefore argue that local interactions between the Mgat5/galectin lattice, Rho/ROCK and Src signalling and downstream phosphorylation of pY14Cav1 at FA sites promote tumor cell migration by regulating local FA dynamics in protrusive domains of tumor cells.

description: Abstract: Family ensures the stability of society, evolves along with it, and acts as a social space in which personal development takes place. State support measures are generally aimed at the socio-economic wellbeing of the family structure. At the same time, the psychological effect of these support measures remains uncertain. The analysis of historical experience of state policy intervention in family relations can serve as a basis for modeling the future. In the last 30-50 years of the 20th century, a boarding school system was introduced for children of northern peoples who lead a nomadic lifestyle. Researchers have noted that the violation of child-parent relationships has led to a number of significant psychological problems, including in family relationships and violation of ethnic identity. The purpose of the current study was to investigate the representation of family identity in the self-concept of the indigenous peoples of Yakutia. Research method: “Who am I?”. The article compares the sakha and indigenous peoples of the north: evens, evenks, yukagirs, chukoch and dolgan. The sample consists of 586 people aged 12 to 79. It was revealed that the self-concept of modern residents of Yakutia reflected the features of the traditional mentality of indigenous peoples. However, the family identity of the indigenous peoples of the north was less represented than that of the sakha. Thus, the results of our research confirm the impact of state measures on the self-concept of the individual.

description: Exchange interactions in α- and γ-Fe are investigated within an ab-initio spin spiral approach. We have performed total energy calculations for different magnetic structures as a function of lattice distortions, related with various cell volumes and the Bain tetragonal deformations. The effective exchange parameters in γ-Fe are very sensitive to the lattice distortions, leading to the ferromagnetic ground state for the tetragonal deformation or increase of the volume cell. At the same time, the magnetic-structure-independent part of the total energy changes very slowly with the tetragonal deformations. The computational results demonstrate a strong mutual dependence of crystal and magnetic structures in Fe and explain the observable "anti-Invar" behavior of thermal expansion coefficient in γ-Fe.

description: Abstract: The development of artificial intelligence technologies is currently rapidly advancing. It can be understood as a set of technological solutions that allow the simulation human cognitive functions (including self-learning and searching for solutions without a predetermined algorithm), obtaining results that are at least comparable to the results of human intellectual activity. Some AI-based technologies are included in our daily lives today. The lack of a philosophical assessment of the prospects for using AI technologies in terms of values entails an increase of social, ethical, legal, and psychological risks of its use. Herein are presented some of the most discussed risks of using AI technology with or by children. In the field of education, these are the risks of the reproduction of inequality (in cases of using adaptive learning systems); risks of unplanned discrimination (in the case of advisory programs); the risks of decreasing motivation and the formation of gaming addictions (in the case of gaming intellectual learning technologies) and others. The use of AI technologies in childcare can lead to a threat to human dignity, and a problem of distribution of responsibility.

description: Eine hohe Innovationsfähigkeit ist die Voraussetzung für die Sicherung der Wettbewerbsfähigkeit von Unternehmen in einer globalisierten Welt. Insbesondere kleinen und mittleren Unternehmen (KMU) fehlt es jedoch an Ressourcen, um im zunehmend beschleunigten Innovationswettlauf mitzuhalten. Daher sind KMU besonders darauf angewiesen, die eigene Kompetenz mit dem komplementären Wissen und Handeln anderer Organisationen zu verknüpfen. Insbesondere Kooperationen in frühen Phasen des Innovationsprozesses scheinen Potential zur Verbesserung der Innovationsfähigkeit zu bieten, sind jedoch bisher kaum wissenschaftlich untersucht. Aufgabe dieser Studie ist es daher, das Kooperationsverhalten von kleinen und mittleren Unternehmen in frühen Phasen des Innovationsprozesses zu analysieren. Die Forschungsgrundlage bildet eine im Rahmen dieser Studie durchgeführte empirische Studie, an der 76 KMU aus der Branche „Medizin-/Instrumententechnik“ teilgenommen haben. Erfasst und detailliert analysiert wird, welches Potential Unternehmen in Kooperationen sehen, wie diese Potentiale bisher und zukünftig umgesetzt werden und welche Schwierigkeiten im Zusammenhang mit Kooperationen auftreten. Die Ergebnisse der Untersuchung zeigen, dass Kooperationen in den frühen Phasen des Innovationsprozesses eine wichtige Rolle spielen. KMU sehen in ihnen vor allem Potential zur Steigerung der Qualität von entwickelten Ideen und Konzepten durch den Zugang zu Know-how und Marktkenntnis. Zur Realisierung des Potentials bezieht ein großer Teil der KMU verschiedene Partner schon in die frühen Phasen ein, wobei Kunden die mit Abstand wichtigsten Kooperationspartner sind. Trotz der festgestellten hohen Kooperationsaktivität zeigen die Untersuchungsergebnisse, dass ungenutztes Kooperationspotential insbesondere in der Zusammenarbeit mit Hochschulen und Forschungseinrichtungen besteht. Die vorliegende Studie identifiziert Barrieren, die für einen zukünftigen Ausbau der benannten Kooperationen im Vorfeld reduziert werden sollten und liefert diesbezüglich Handlungsempfehlungen zur Steigerung der Innovationsfähigkeit von KMU.

Hepatic microsomal bile acid biotransformation : identification of metabolites and cytochrome p450 enzymes involved
Creators: name: Deo, Anand K.
Publisher: name: University of British Columbia
Year: 2009

description: Bile acids are end-products of cholesterol metabolism and essential for absorption of dietary lipids in the body. Impaired bile flow leads to hepatic bile acid accumulation and liver damage. Hepatic microsomal oxidation offers a potential mechanism for efficient elimination of bile acids. The present study investigated the cytochrome P450 (P450)-mediated hepatic microsomal biotransformation profiles of lithocholic acid, cholic acid and chenodeoxycholic acid using a liquid chromatography-mass spectrometry (LCIMS) based assay. Incubation of lithocholic acid with rat hepatic microsomes resulted in the formation of a major 6β-hydroxylated metabolite, murideoxycholic acid, followed by isolithocholic acid and 3-ketocholanoic acid. Ursodeoxycholic acid, hyodeoxycholic acid and 6-ketolithocholic acid were identified as minor metabolites. Studies using P450-specific antibodies, chemical inducers, and rat recombinant enzymes showed that formation of murideoxycholic acid and 3-ketocholanoic acid were mediated by CYP3A2 and CYP2C 11. Similar metabolite profiles were obtained by incubation of lithocholic acid with mouse hepatic microsomes generating murideoxycholic acid as the major metabolite. Studies using P450 inducers and chemical inhibitors suggested the involvement of murine CYP3A in murideoxycholic acid and 3-ketocholanoic acid formation, and CYP1A, CYP2B and CYP3A enzymes in ursodeoxycholic acid, hyodeoxycholic acid and 6-ketolithocholic acid formation by mouse liver microsomes. Biotransformation of lithocholic acid by human hepatic microsomes generated 3-ketocholanoic acid as the major metabolite, and hyodeoxycholic acid, ursodeoxycholic acid, 6-ketolithocholic acid and murideoxycholic acid, as minor metabolites. Studies with chemical inhibitors and human recombinant enzymes demonstrated that CYP3A4 catalyzed the formation of all five metabolites. The biotransformation of cholic acid and chenodeoxycholic acid by human hepatic microsomes revealed the formation of a single cholic acid metabolite, 3-dehydrocholic acid. Chenodeoxycholic acid biotransformation generated 7α-hydroxy-3 -oxo-5β-cholan-24-oic acid as the major metabolite followed by у-muricholic acid, 7-ketolithocholic acid and cholic acid, respectively. CYP3A4 was found to be the major enzyme involved in the biotransformation of cholic acid and chenodeoxycholic acid in human liver microsomes. A comparison of metabolite profiles demonstrated the dominant role of human CYP3A4 in the oxidation of bile acids at the C-3 position. In contrast, 6β-hydroxylation catalyzed by multiple P450 (CYP1A, CYP2B, CYP2C and CYP3A) enzymes was the preferred biotransformation pathway in rodent liver microsomes.

description: Abstract: The social situation of the development of the child (L.S.Vygotsky) of preschool age includes a set of conditions that ensures the individualization of a child’s development and entry into the world of human culture. In modern society, these conditions are determined by the nature of the interaction between the main subjects of the preschool educational process (N.E.Veraksa, S.A.Kozlova) in the context of developing preschool education. This is done through the use of technologies (E.O.Smirnova) that improve the quality of information communication when interacting with parents of pupils. The empirical study included the following: identification of the difficulties of organizing the educational process in a pandemic (questionnaire of preschool teachers, n = 261), evaluation of the organization's effectiveness and remote forms of interaction of pedagogical preschool workers with parents of pupils (questionnaire of legal representatives of pupils, n = 321). Legal representatives of pupils were mainly satisfied (78.8% completely, 19.3% partially) with the organization of the preschool educational process during the pandemic. Parents and teachers identified common difficulties in organizing the educational process as relating to the organization of holidays and entertainment. The importance of the development and use of online content to improve the interaction between teachers and parents was confirmed. The parents’ preferred forms of information and communication technologies were the use of social networks, parental online meetings, online consultations and educational portals for parents. The optimization of the forms and content of interactions with parents can ensure the improvement of the quality of the educational environment.

description: We characterize the positively charged exciton (X1+) in single InGaAs quantum dots using resonant laser spectroscopy. Three samples with different dopant species (Be or C as acceptors, Si as a donor) are compared. The p-doped samples exhibit larger inhomogeneous broadening (x3) and smaller absorption contrast (x10) than the n-doped sample. For X1+ in the Be-doped sample, a dot dependent non-linear Fano effect is observed, demonstrating coupling to degenerate continuum states. However, for the C-doped sample the X1+ lineshape and saturation broadening follows isolated atomic transition behaviour. This C-doped device structure is useful for single hole spin initialization, manipulation, and measurement.

description: Die Auswahl einer Klebmasse stellt einen entscheidenen Schritt bei der Entwicklung eines neuen transdermalen Pflastersystems (TDDS) dar. In dieser Arbeit wurde die perkutane Absorption von Wirkstoffen bei der Anwendung adhäsiver transdermaler Systeme untersucht. Diffusionsprozesse innerhalb der Klebmasse eines TDDS konnten dabei mit Hilfe einer eigens dafür neu entwickelten Methode basierend auf konfokaler Raman Mikroskopie betrachtet werden. Aus den in den Studien gewonnen Erkenntnissen wurde ein neues Konzept für die Entwicklung eines TDDSs erstellt. Dieses Konzept konnte abschließend anhand von zwei Wirkstoffen erfolgreich getestet werden.
description: The selection of a suitable pressure sensitive adhesive represents an important step in the design of a transdermal drug delivery system (TDDS). In this study the percutaneous absorption of drugs during the application of adhesive TDDSs was investigated. Diffusion processes within the adhesive of a TDDS could be observed with a newly developed method based on confocal Raman microscopy. With the knowledge gained in these studies a new concept for the development of a TDDS was established. Finally this concept was tested successfully with two different drugs.
Origin of Cosmic Rays

description: It is argued that there are three `origins' of cosmic rays; the origin of the particles, the origin of the energy, and the site of the acceleration. The evidence for each origin is discussed and a plausible synthesis outlined for the particles of Galactic origin where the energy comes mainly (but not exclusively) from supernova explosions, the site of the acceleration is at strong collisionless shock waves, and the accelerated particles come from the interstellar and circumstellar material swept over by these shocks. If these shocks are capable (as indicated by recent observations and theoretical work) of significantly amplifying magnetic fields this picture appears capable of explaining the cosmic ray particles at all energies below the `ankle' at $3\times10^{18}\,\rm eV$. The particles above this energy are generally taken to be of extra-galactic origin and possible acceleration sites for these UHE particles are briefly discussed.

description: Contemporary children spend less time involved in free play, and developed forms of role play are rather seldom found . These trends are associated with the emergence of global informatization and digitalization. Many scholars argue that a new cultural and historical type of childhood "digital childhood" has developed. The current study focuses on identifying specific traits of play activity in children with high levels of screen time. Research methods include the "Method of diagnostics of role-playing games" by E.O. Smirnova, I.A. Ryabkova and "Diagnostics of the development of playing skills" by R.R. Kalinina, as well as a questionnaire elaborated by the authors to evaluate different aspects of children’s interaction with digital content. The empirical study was conducted from December 2019 to January 2021. 13 children between 4 and 6 years of age participated in the longitudinal study. The analysis of the collected data showed that the level of computer activity was associated with characteristics of play activity such as subject substitution; interaction, organizing the game; plot elaboration; role behavior; play actions; the use of attributes and implementation of rules. The more time the child spent interacting with gadgets, the lower the indicated characteristics of play. The results 20 of the study are interesting for psychologists, educators, and parents, and may be used particularly in elaborating recommendations concerning preschoolers’ interaction with digital media.

description: We show that the Modified Newtonian Dynamics (MOND) regime can be fully recovered as the weak-field limit of a particular theory of gravity formulated in the metric approach. This is possible when Milgrom's acceleration constant is taken as a fundamental quantity which couples to the theory in a very consistent manner. As a consequence, the scale invariance of the gravitational interaction is naturally broken. In this sense, Newtonian gravity is the weak-field limit of general relativity and MOND is the weak-field limit of that particular extended theory of gravity.

description: We perform high-resolution hydrodynamic simulations of a Milky Way-mass galaxy in a fully cosmological setting using the adaptive mesh refinement code, Enzo, and study the kinematics of gas in the simulated galactic halo. We find that the gas inflow occurs mostly along filamentary structures in the halo. The warm-hot (10^5 K < T < 10^6 K) and hot (T > 10^6 K) ionized gases are found to dominate the overall mass accretion in the system (with dM/dt = 3-5 M_solar/yr) over a large range of distances, extending from the virial radius to the vicinity of the disk. Most of the inflowing gas (by mass) does not cool, and the small fraction that manages to cool does so primarily close to the galaxy (R

Ein Beitrag zur Bestimmung der Grenzlast von Aluminiumträgern mit kreisförmigen Stegausschnitten

description: Ein Beitrag zur Bestimmung der Grenzlast von Aluminiumträgern mit kreisförmigen Stegausschnitten Außer für die Aufbauten bei Seeschiffen kommt Aluminium aufgrund seines geringen spezifischen Gewichtes als Werkstoff besonders im Kleinschiffbau zum Einsatz. So werden beispielsweise Rettungskreuzer der Deutschen Gesellschaft zur Rettung Schiffbrüchiger (DGzRS) sowie Einsatzfahrzeuge der Behörden (Zoll-, Feuerwehrund Wasserschutzpolizeiboote) und Luftkissenfahrzeuge oft komplett aus Aluminium gefertigt. Durch ein relativ enges Netz aus Längs- und Querspanten erhält der Bootskörper ausreichende Festigkeit gegenüber den Beanspruchungen im Einsatz. Die Verwendung von Leichtmetall kommt außerdem einer hohen Geschwindigkeit zu Gute, was eine Hauptanforderung beim Entwurf dieser Boote darstellt. Um jede weitere Möglichkeit zur Gewichtsreduzierung auszunutzen, werden in den Stegen der tragenden Verbände (Querrahmen und Längsträger) oft kreisförmige Erleichterungslöcher vorgesehen, die gleichzeitig zur Durchführung von Kabelbahnen und Leitungen jeglicher Art aus Gründen der Platzersparnis unumgänglich sind. Die Ausschnitte führen allerdings zu einer Schwächung der Träger. Die Versagensart dieser ausgeschnittenen Biegeträger ist abhängig von der Art der Belastung, der Schlankheit der Träger und ganz besonders von der Form und Größe der Stegausschnitte. Ein Versagen kann eintreten durch: Schubbeulen der Stege,Schubbrüche an Schweißnähten,Biegemechanismus (Fließgelenkbildung), Normal- und Querkraftmechanismus infolge hoher Kerbspannungen. Besondere Bedeutung in dieser Arbeit kommt dem letzten Punkt und somit den Stegausschnitten zu, da diese Kerben darstellen. Als Kerben werden in diesem Zusammenhang allgemein Querschnittstörungen in einem Bauteil durch Ausschnitte, Einschnitte und Übergänge bezeichnet, die bei der Beanspruchung des Bauteils Störungen des Spannungsverlaufes zur Folge haben. Diese Störungen äußern sich in lokalen Spannungserhöhungen, die zum Versagen des Bauteils durch Riß- oder Bruchvorgänge führen können. Die Kerbwirkung unterscheidet sich dabei im wesentlichen nach der Art der Belastung des auteils und der Geometrie der Ausschnitte. Durch die elastizitätstheoretische Formzahl wird das Verhältnis der maximalen örtlichen Spannung zu einer festzulegenden Nenn- oder Vergleichsspannung als Maß für die Kerbwirkung erfaßt.

description: This paper shows the experimental details of the stabilization scheme that allows full control of the repetition rate and the carrier-envelope offset frequency of a 10 GHz frequency comb based on a femtosecond Ti:sapphire laser. Octave-spanning spectra are produced in nonlinear microstructured optical fiber, in spite of the reduced peak power associated with the 10 GHz repetition rate. Improved stability of the broadened spectrum is obtained by temperature-stabilization of the nonlinear optical fiber. The carrier-envelope offset frequency and the repetition rate are simultaneously frequency stabilized, and their short- and long-term stabilities are characterized. We also measure the transfer of amplitude noise of the pump source to phase noise on the offset frequency and verify an increased sensitivity of the offset frequency to pump power modulation compared to systems with lower repetition rate. Finally, we discuss merits of this 10 GHz system for the generation of low-phase-noise microwaves.
