description: Anatomische Präparate stehen für die individuellen Lebensgeschichten von Personen, deren Leichname auf unterschiedlichsten Wegen an Anatomische Institute gelangten. Die makroskopische Sammlung der Innsbrucker Anatomie umfasst gegenwärtig gleich mehr als 4.000 Einzelobjekte, wovon etwas mehr als die Hälfte aus Trocken- und Feuchtpräparaten humanen Ursprungs besteht. Um zu verstehen, warum solche Sammlungen überhaupt existieren, ist einleitend die Geschichte der Universität Innsbruck und ihrer anatomischen Lehrkanzel, die älteste ihrer Art in Österreich, wiedergegeben. Mangel an menschlichen Leichnamen war Alltag an Anatomischen Instituten; ursächlich hierfür war, dass lange Zeit ausschließlich Hingerichtete für Lehre und Forschung seziert werden durften. Die Situation änderte sich erst zu Beginn des 20. Jahrhunderts, vor allem mit der Machtübernahme der Nationalsozialisten. Gleichzeitig gestaltete sich die Provenienz der Leichname während dieser Jahre besonders schwierig. Zwischen 1938 und 1943 gelangten 199 Leichname, darunter von 59 im Gefängnis München-Stadelheim Hingerichteten, an die Innsbrucker Anatomie. Eine systematische Aufarbeitung dieser Epoche ist dringend notwendig, ein entsprechendes Forschungsprojekt wurde Mitte 2016 initiiert. Die Identifizierung von Präparaten, welche während der NS-Zeit angefertigt wurden, gehört zu den vorrangigen Aufgaben dieses Projekts. In diesem Beitrag werden nun erste Ergebnisse präsentiert: Bislang konnte ein Präparat eindeutig mit einem während der NS-Zeit in München-Stadelheim hingerichteten Mann in Verbindung gebracht werden. Bei drei weiteren Objekten ist durch das Alter und den Herstellungszeitraum die Verknüpfung mit zwei, bei einem Objekt gleich mit drei unterschiedlichen Personen möglich. Zurzeit können mehr als 1.000 Human- und Tierpräparate als vor 1938 entstanden eingestuft werden. Die restlichen Objekte müssen noch näher untersucht werden.

description: Internet-of-Things (IoT) and cyber-physical systems (CPSs) may consist of thousands of devices connected in a complex network topology. The diversity and complexity of these components present an enormous attack surface, allowing an adversary to exploit security vulnerabilities of different devices to execute a potent attack. Though significant efforts have been made to improve the security of individual devices in these systems, little attention has been paid to security at the aggregate level. In this article, we describe a comprehensive risk management system, called GRAVITAS, for IoT/CPS that can identify undiscovered attack vectors and optimize the placement of defenses within the system for optimal performance and cost. While existing risk management systems consider only known attacks, our model employs a machine learning approach to extrapolate undiscovered exploits, enabling us to identify attacks overlooked by manual penetration testing (pen-testing). The model is flexible enough to analyze practically any IoT/CPS and provide the system administrator with a concrete list of suggested defenses that can reduce system vulnerability at optimal cost. GRAVITAS can be employed by governments, companies, and system administrators to design secure IoT/CPS at scale, providing a quantitative measure of security and efficiency in a world where IoT/CPS devices will soon be ubiquitous.

Stesichorus and the epic tradition
Creators: name: Maingon, Alison Dale
Publisher: name: University of British Columbia
Year: 2010

description: In antiquity Stesichorus was labelled "Homeric" by the commentators, but his innovation in myth was also noted. Until the discovery of fragments of his poems among the papyri from Oxyrhynchus there was little material from which any conclusions could be reached regarding the poet's treatment of his inheritance from the epic tradition. In this dissertation,therefore , I have examined the new evidence from the papyri with a view to assessing the poet's reliance upon that tradition in both diction and content, and the extent to which he was innovative. The poet's language at a morphological level is seen to be almost identical to that of epic, whereas at the level of phonology the intrusion of a Western or "Doric" pronunciation has occurred. The poets adaptation of Homeric "formulae" reveals a prevalent tendency to avoid the repetition of phrases commonly found in the epic corpus by the introduction of new, unprecedented word-associations. In chapter VI a detailed examination of four of the fragments of four poems,(the Nostoi, the Sack of Troy, the Geryoneis and the Suotherae) indicates the ways in which the poet adapted thematic elements from the epic tradition, amalgamating epic with non-epic , conventional with original material. The second half of this dissertation is devoted to Stesichorus' treatment of the inherited body of Greek myth. In those poems in which the poet was concerned with the legends of mainland Greece, innovations appear , with the exception of the Palinode, not to alter the basic structure of the myths. However, there is evidence of the poet's interest in elaborating upon or inventing legends located in the Greek west, notably in poems relating the exploits of Heracles, but also in his orestela and Sack of Troy. In so doing the poet would create or give authority to a body of myths specifically relevant to his western audience.
An alternative form of Hooge's relation for 1/f noise in semiconductor materials
Creators: name: Grueneis, Ferdinand
Publisher: name: arXiv
Year: 2021
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: Single quantum dots and other materials exhibit irregular switching between on and off states; these on-off states follow power-law statistics giving rise to 1/f noise. We transfer this phenomenon (also referred to as on-off intermittency) to the generation and recombination (g-r) process in semiconductor materials. In addition to g-r noise we obtain 1/f noise that can be provided in the form of the Hooge relation. The predicted Hooge coefficient depends on the parameters of the g-r noise and on the parameters of the intermittency. Due to the power-law distribution of the on-times, the coefficient for intermittency shows a smooth dependence on time t. We also suggest an alternative form of the 1/f noise formula by Hooge relating the 1/f noise to the number of centers (such as donor or trap atoms) rather than to the number of charge carriers as defined by Hooge.

description: The Crab nebula is a prominent pulsar wind nebula (PWN) detected in multiband observations ranging from radio to very high-energy (VHE) $γ$-rays. Recently, $γ$-rays with energies above $1 \mathrm{PeV}$ had been detected by the Large High Altitude Air Shower Observatory (LHAASO), and the energy of the most energetic particles in the nebula can be constrained. In this paper, we investigate the broadest spectral energy distribution of the Crab nebula and the energy distribution of the electrons emitting the multiwavelength nonthermal emission based on a one-zone time-dependent model. The nebula is powered by the pulsar, and high-energy electrons/positrons with a broken power-law spectrum are continually injected in the nebula as the pulsar spins down. Multiwavelength nonthermal emission is generated by the leptons through synchrotron radiation and inverse Compton scattering. Using appropriate parameters, the detected fluxes for the nebula can be well reproduced, especially for the $γ$-rays from $10^2\,\mathrm{MeV}$ to $1\,\mathrm{PeV}$. The results show that the detected $γ$-rays can be produced by the leptons via the inverse Compton scattering, and the lower limit of the Lorentz factor of the most energetic leptons is $\sim 8.5\times10^{9}$. It can be concluded that there are electrons/positrons with energies higher than $4.3$\,PeV in the Crab nebula.

The consequences of non-differentiable angular dispersion in optics: Tilted pulse fronts versus space-time wave packets
Creators: name: Hall, Layton A.

Year: 2021

description: Conventional diffractive and dispersive devices introduce angular dispersion (AD) into pulsed optical fields thus producing so-called 'tilted pulse fronts'. Naturally, it is always assumed that the functional form of the wavelength-dependent propagation angle associated with AD is differentiable with respect to wavelength. Recent developments in the study of space-time wave packets -- pulsed beams in which the spatial and temporal degrees of freedom are inextricably intertwined -- have pointed to the existence of non-differentiable AD: field configurations in which the propagation angle does not possess a derivative at some wavelength. Here we investigate the consequences of introducing non-differentiable AD into a pulsed field and show that it is the crucial ingredient required to realize group velocities that deviate from $c$ (the speed of light in vacuum) along the propagation axis in free space. In contrast, the on-axis phase and group velocities are always equal in conventional scenarios. Furthermore, we show that non-differentiable AD is needed for realizing anomalous or normal group-velocity dispersion along the propagation axis, while simultaneously suppressing all higher-order dispersion terms. These and several other consequences of non-differentiable AD are verified experimentally using a pulsed-beam shaper capable of introducing AD with arbitrary spectral profile. Rather than being an exotic phenomenon, non-differentiable AD is an accessible, robust, and versatile resource for sculpting pulsed optical fields.

description: Rail transportation, especially, high-speed rails (HSR), is an important infrastructure for the development of national economy and the promotion of passenger experience. Due to the large bandwidth, millimeter wave (mmWave) communication is regarded as a promising technology to meet the demand of high data rates. However, since mmWave communication has the characteristic of high attenuation, mobile relay (MR) is considered in this paper. Also, full-duplex (FD) communications have been proposed to improve the spectral efficiency. However, because of the high speed, as well as the problem of penetration loss, passengers on the train have a poor quality of service. Consequently, an effective user association scheme for HSR in mmWave band is necessary. In this paper, we investigate the user association optimization problem in mmWave mobilerelay systems where the MRs operate in the FD mode. To maximize the system capacity, we propose a cooperative user association approach based on coalition formation game, and develop a coalition formation algorithm to solve the challenging NP-hard problem. We also prove the convergence and Nashstable property of the proposed algorithm. Extensive simulations are done to show the system performance of the proposed scheme under various network settings. It is demonstrated that the proposed distributed low complexity scheme achieves a nearoptimal performance and outperforms two baseline schemes in terms of average system throughput.

description: You have in front of you the proceedings of the 5th International Workshop on Worst-Case
Execution Time (WCET) Analysis. The workshop was held on the 5th of July 2005 as a satellite event
to the 17th Euromicro Conference on Real-Time Systems (ECRTS 2005) in Palma de Mallorca, Spain.
It was the fifth event in the series after the successful meetings in Delft (Holland) in 2001, Vienna
(Austria) in 2002, Porto (Portugal) in 2003 and Catania (Italy) in 2004. The goal of these workshops is
to bring together people from academia, tool vendors and users in industry that are interested in all
aspects of timing analysis for real-time systems. The workshops provide a relaxed forum to present and
discuss new ideas, new research directions, and to review current trends in this area. It consisted of short
presentations that should encourage discussion by the attendees. The topics of the 2005 workshop
included paper on the following topics:
- Measurement-based timing-analysis methods,
- Experience from industrial case studies,
- Architectural issues, and
- Timing analysis in real-time education.
In addition, there was an invited talk by Lothar Thiele, ETH Zuerich, on Composable Real-Time
Analysis. There is no paper about this talk contained in the proceedings.
The industrial case studies showed that the techniques have matured to industrial applicability.
Better results are achieved if the methods and tools are integrated into the development process.
Measurement-based methods were controversially discussed. Further talks showed that much support is
needed to deal with architectural features that endanger timing predictability.

Burying as a defensive response in rats
Creators: name: Treit, Dallas R.
Publisher: name: University of British Columbia
Year: 2010

description: In typical laboratory settings, the defensive reactions of animals appear to be limited tofreezing, fleeing, and attacking. However, in the present investigations, rats tested in the presence of movable material incorporated it into a striking and adaptive behavioural sequence. Rats shocked once through a stationary prod buried this shock source, even when the shocks-test interval was 20 days. This burying behaviour occurred at a variety of shock intensities and seemed to be controlled specifically by the relation between the shock and the prod; rats shocked through a grid did not bury the prod, and rats shocked by one of two identical prods buried only the shock-prod. Both the position and brightness of the prod seemed to control the burying behaviour. When either of these cues was changed prior to the test, burying behaviour was disrupted compared to control conditions in which these cues were unaltered. Although burying was a directed and consistent response of rats to prod shock, it was not a simple, reflexive behaviour; rats could adapt their burying behaviour to changes in both the kind and disposition of burying materials. Thus, the usual assumption that the rat's defensive repertoire is limited to a few simple behaviours appears to have been shaped by the constraints of standard testing environments rather than by the actual propensities of the rat. These results were discussed in terms of their implications for a "biological" approach to aversive learning.
Kinetic investigation of the planar Multipole Resonance Probe in the low-pressure plasma

description: Active Plasma Resonance Spectroscopy (APRS) is a well-established plasma diagnostic method: a radio frequency signal is coupled into the plasma via a probe or antenna, excites it to oscillate, and the response is evaluated through a mathematical model. The majority of APRS probes are invasive and perturb the plasma by their physical presence. The planar Multipole Resonance Probe (pMRP) solves this problem: it can be integrated into the chamber wall and minimizes the perturbation. Previous work has studied the pMRP in the frame of the Drude model, but it misses important effects like collision-less damping. In this work, a collision-less kinetic model is developed to further investigate the behavior of the pMRP. This model consists of the Vlasov equation, which is coupled with the Poisson equation under electrostatic approximation. The spectral response of the probe-plasma system is found by calculating the complex admittance. This model covers the kinetic effects and overcomes the limitations of the Drude model.

Damit wird der bisherige Höchstwert von rund 64.000 Personen aus dem Jahr 2019 vor der Coronapandemie deutlich übertroffen. Ein Treiber dafür sind die hohen Fachkräfteengpässe in den Unternehmen, die nach einer aktuellen Befragung mehr als Zweidrittel von ihnen betreffen. Gleichzeitig ist die Anwerbepraxis der Unternehmen aus dem Ausland weiterhin zurückhaltend, wie unsere diesjährige Unternehmensbefragung zeigt. Der Fachkräftemigrationsmonitor 2023 analysiert die Zahlen zur Zu- und Abwanderung von Arbeits- und Fachkräften aus dem Ausländerzentralregister für das Jahr 2022, die auf der Personenstatistik der Ausländerbehörden basieren. Zugleich erhebt er zum vierten Mal die Einschätzungen der Unternehmen zum Fachkräftemangel und Rekrutierungspraxis mittels einer Online-Umfrage des Meinungsforschungsunternehmens CIVEY.

description: Spin defects in wide-bandgap semiconductors provide a promising platform to create qubits for quantum technologies. Their synthesis, however, presents considerable challenges, and the mechanisms responsible for their generation or annihilation are poorly understood. Here, we elucidate spin defect formation processes in a binary crystal for a key qubit candidate--the divacancy complex (VV) in silicon carbide (SiC). Using atomistic models, enhanced sampling simulations, and density functional theory calculations, we find that VV formation is a thermally activated process that competes with the conversion of silicon ($V_{Si}$) to carbon monovacancies ($V_{C}$), and that VV reorientation can occur without dissociation. We also find that increasing the concentration of $V_{Si}$ relative to $V_{C}$ favors the formation of divacancies. Moreover, we identify pathways to create spin defects consisting of antisite-double vacancy complexes and determine their electronic properties. The detailed view of the mechanisms that underpin the formation and dynamics of spin defects presented here may facilitate the realization of qubits in an industrially relevant material.

description: We discover new vacuum solutions of the JIMWLK equation, which correspond to center of a gauge group. We improve the color glass condensate (CGC) model by an explicit usage of a density matrix. Studying scattering of CGC states in an external color field, we observe that an amplitude is naturally expressed via group characters. We construct an example that shows how new thin effects may be potentially observed in peripheral collisions. We prove that at any parton density a gluonic CGC state does not become a true black disk. We find a wave function of a true black disk and show that it necessarily contains many quarks. This result corresponds to the necessity of nonvacuum Reggeon loops in a formation of a true black disk.

description: We study the spin Hall effect (SHE) in graphene using a realistic multi-orbital tight-binding model that includes the atomic spin-orbit interaction. The SHE is found to be induced by the spin-dependent Aharonov-Bohm phase. In the metallic case, the calculated values for the spin Hall conductivity (SHC) are much smaller than the quantized Hall conductivity for realistic parameter values of metallic graphene. In the insulating case, quantization of the SHC is violated due to the multi-orbital effect. The present study suggests that the SHE in a honeycomb lattice is enhanced by chemical doping, such as the substitution of carbon atoms with boron atoms.

description: We investigate the bias dependence of the tunneling conductance between a spin-polarized (SP) scanning tunneling microscope (STM) tip and the surface conduction states of a normal metal with a Kondo adatom. Quantum interference between tip-host metal and tip-adatom-host metal conduction paths is studied in the full range of the Fano parameter $q$. The spin-polarized STM gives rise to a splitting of the Kondo peak and asymmetry in the zero-bias anomaly depending on the lateral tip-adatom distance. For increasing lateral distances, the Kondo peak-splitting shows a strong suppression and the spin-polarized conductance exhibits the standard Fano-Kondo profile.

description: We compute finite volume effects relevant for lattice QCD simulations using background fields. Focusing on constant electric and magnetic fields on a periodic lattice, we determine volume corrections to pion two-point functions using chiral perturbation theory. Among such corrections are the finite volume shifts to the electric and magnetic polarizabilities, which are numerically shown to be non-negligible. We additionally find that all terms in the single-particle effective action can be renormalized by infrared effects. This includes Born couplings to the pion current and total charge-squared, which can be renormalized due to the nature of gauge invariance on a torus.

Analysis and fabrication of MIS solar cells with majority carrier conduction characteristics
Creators: name: Au, Ho Piu
Publisher: name: University of British Columbia
Year: 2010

description: A simple model for a MIS solar cell incorporating the effects of inversion layer charge and non-uniform surface state charge has been generated. The inclusion of these terms in the analysis results in theoretical In I-V characteristics which, under forward bias in the dark, have a two slope nature very similar to that of practical MIS solar cells that have been reported to be operating in a minority carrier conduction mode. As the present model considers solely majority carrier conduction, an alternative explanation of the operation of these devices can be proposed. Experimental data were obtained from Al/SiO[sub x]/pSi solar cells and good agreement with the proposed theory was obtained.

description: Understanding the behaviour of topologically ordered lattice systems at finite temperature is a way of assessing their potential as fault-tolerant quantum memories. We compute the natural extension of the topological entanglement entropy for T > 0, namely the subleading correction $I_{\textrm{topo}}$ to the area law for mutual information. Its dependence on T can be written, for Abelian Kitaev models, in terms of information-theoretic functions and readily identifiable scaling behaviour, from which the interplay between volume, temperature, and topological order, can be read. These arguments are extended to non-Abelian quantum double models, and numerical results are given for the $D(S_3)$ model, showing qualitative agreement with the Abelian case.

description: Bound-state (BS) formation in quantum point contacts (QPCs) may offer a convenient way to localize and probe single spins. In this letter, we investigate how such BSs are affected by monitoring them with a second QPC, which is coupled to the BS via wavefunction overlap. We show that this coupling leads to a unique detector backaction, in which the BS is weakened by increasing its proximity to the detector. We also show, however, that this interaction between the QPCs can be regulated at will, by using an additional gate to control their wavefunction overlap.

description: An efficient method is proposed for numerical solutions of nonlinear Schrödinger equations in an unbounded domain. Through approximating the kinetic energy term by a one-way equation and uniting it with the potential energy equation, absorbing boundary conditions are designed to truncate the unbounded domain, which are in nonlinear form and can perfectly absorb the waves outgoing from the truncated domain. We examine the stability of the induced initial boundary value problems defined on the computational domain with the boundary conditions by a normal mode analysis. Numerical examples are given to illustrate the stable and tractable advantages of the method.

description: In quantum theory, for a system with macroscopic wavefunction, the charge density and current density are represented by non-commuting operators. It follows that the anomaly $I=\partial_t ρ+ \nabla \cdot \mathbf{j}$, being essentially a linear combination of these two operators in the frequency-momentum domain, does not admit eigenstates and has a minimum uncertainty fixed by the Heisenberg relation $ΔN Δϕ\simeq 1$ which involves the occupation number and the phase of the wavefunction. We give an estimate of the minimum uncertainty in the case of a tunnel Josephson junction made of Nb. Due to this violation of the local conservation of charge, for the evaluation of the e.m. field generated by the system it is necessary to use the extended Aharonov-Bohm electrodynamics. After recalling its field equations, we compute in general form the energy-momentum tensor and the radiation power flux generated by a localized oscillating source. The physical requirements that the total flux be positive, negative or zero yield some conditions on the dipole moment of the anomaly $I$.

description: The moiré pattern observed in stacked non-commensurate crystal lattices, such as hetero-bilayers of transition metal dichalcogenides, produces a periodic modulation of their bandgap. Excitons subjected to this potential landscape exhibit a band structure that gives rise to a quasi-particle dubbed moiré exciton. In the case of MoS$_2$/WSe$_2$ hetero-bilayers, the moiré trapping potential has honeycomb symmetry and, consequently, the moiré exciton band structure is the same as that of a Dirac-Weyl fermion, whose mass can be further tuned down to zero with a perpendicularly applied field. Here we show that, analogously to other Dirac-like particles, moiré exciton exhibits a trembling motion, also known as zitterbewegung, whose long timescales are compatible with current experimental techniques for exciton dynamics. This promotes the study of the dynamics of moiré excitons in van der Waals heterostructures as an advantageous solid-state platform to probe zitterbewegung, broadly tunable by gating and inter-layer twist angle.

description: We present the results of a series of optical, UV, X-ray and gamma-ray observations of the BL Lac object S50716+714 carried out by the Swift and AGILE satellites in late 2007 when this blazar was flaring close to its historical maximum at optical frequencies. We have found that the optical through soft X-ray emission, likely due to Synchrotron radiation, was highly variable and displayed a different behavior in the optical UV and soft X-ray bands. The 4-10 keV flux, most probably dominated by the inverse Compton component, remained instead constant. The counting statistics in the relatively short AGILE GRID observation was low and consistent with a constant gamma-ray flux at a level similar to the maximum observed by EGRET. An estimate of the gamma-ray spectral slope gives a value of the photon index that is close to 2 suggesting that the peak of the inverse Compton component in the Spectral Energy Distribution (SED) is within the AGILE energy band. The different variability behavior observed in different parts of the SED exclude interpretations predicting highly correlated flux variability like changes of the beaming factor or of the magnetic field in simple SSC scenarios. The observed SED changes may instead be interpreted as due to the sum of two SSC components, one of which is constant while the other is variable and with a systematically higher synchrotron peak energy.

Limitations of coupled cluster approximations for highlyaccurate investigations of Rb$_2^+$

description: We reveal limitations of several standard coupled-cluster (CC) methods with perturbation-theorybased noniterative or approximate iterative treatments of triple excitations when applied to thedetermination of highly accurate potential energy curves (PECs) of ionic dimers, such as the X $^2Σ^+_g$ electronic ground state of Rb$_2^+$. Such computations are of current interest for the understanding ofion-atom interactions in the ultracold regime. We demonstrate that these coupled-cluster methodslead to an unphysical long-range barrier for the Rb$_2^+$ system. The barrier is small but clearly spoilsthe entire long-range behavior of the PEC. The effect is also found for other X$_2^+$ systems, like X = Li, Na, and K. Calculations using a new flexible framework for obtaining leading perturbativetriples corrections derived using an analytic CC singles and doubles (CCSD) energy derivativeformulation demonstrate that the origin of this problem lies in the use of $T_3$ amplitudes obtained from approximate CC singles, doubles and triples (CCSDT) amplitude equations. It is shown thatthe unphysical barrier is related to a symmetry instability of the underlying Hartree-Fock mean-fieldsolution. Physically meaningful perturbative corrections in the long-range tail of the PEC mayinstead be obtained using symmetry-broken reference determinants.

Prolegomenon to an understanding of the Jatra of India : the travelling popular theatre of the state of West Bengal
Creators: name: Farber, Carole
Publisher: name: University of British Columbia
Year: 2010

description: This thesis presents the first extended ethnographic account of a popular professional theatrical form and life-style—the jatra of West Bengal, India. The research material presented and analysed was collected from 1970-1972 in West Bengal and the immediately surrounding states of Assam, Orissa and Bihar. The cognitive universe of the jatra jagat (world), the cultural practice of the jatra business, and the interactional constraints operating among the various categories of people within the jatra profession, are described and interpreted. In addition, this thesis presents the first systematically and anthropologically annotated translation of a popularly performed jatra play, Pariah Paiser Pvithibi (The World for F-ive Paisa). The central point of the thesis revolves around an interpretation of the concerns of the professional jatra business—an aesthetic business, the business of cultural performance. The argument is that this performance form, from its asserted putative origin, has been a critical and self-reflective commentary on Bengali social and cultural life. The jatra is inextricably bound within the existential and cultural dilemmas of Bengali life, dilemmas and contradictions that traditionally were resolved at both metaphysical and practical levels. Now that the jatra is embedded within a capitalist business world, critical commentaries and revolutionary desires remain unresolved within the profession itself. In spite of this, the jatra remains critical of both itself and Bengali social and cultural life, embedded as it is in the current context of feared and despised Western cultural imperialism and internal domination. The anthropological interpretation and analysis presented in the thesis is informed from a number of sources; the views expressed by people within the jatra world, the work in anthropology that currently goes under the heading of 'symbolic anthropology', critical theory and literary criticism, and semiotics. With these points of view in mind, the thesis presents an analysis of the jatra advertising system, the jatra performance system, and a larger peripatetic performance system, as well as a statement about the interpretation of meaning in Bengali life.

description: On the 4th of July, 2006, the 6th International Workshop onWorst-Case Execution Time Analysis (WCET'06)
was held in Dresden, Germany, co-located with the 18th Euromicro International Conference on Real-Time
Systems (ECRTS'06), both with support of Euromicro Technical Committee. The goal of the workshop was
to bring together people from academia, tool vendors and users in industry that are interested in all aspects
of timing analysis for real-time systems. The workshop provided a relaxed forum to present and discuss
new ideas, new research directions, and to review current trends in this area. The workshop was based on
short presentations that should encourage discussion by the attendees.

description: We introduce the beta generalized exponential distribution that includes the beta exponential and generalized exponential distributions as special cases. We provide a comprehensive mathematical treatment of this distribution. We derive the moment generating function and the $r$th moment thus generalizing some results in the literature. Expressions for the density, moment generating function and $r$th moment of the order statistics also are obtained. We discuss estimation of the parameters by maximum likelihood and provide the information matrix. We observe in one application to real data set that this model is quite flexible and can be used quite effectively in analyzing positive data in place of the beta exponential and generalized exponential distributions.

description: We discuss the generation of large-scale magnetic fields due to the breaking of the conformal invariance in the electromagnetic field through the $CPT$-even dimension-six Chern-Simons-like effective interaction with a fermion current in inflationary cosmology. It is shown that the magnetic fields on 1Mpc scale with the field strength of $\sim 10^{-9}$G at the present time can be generated even for the scale of the effective interaction being the Planck scale.
