description: Controlling optical fields on the subwavelength scale is at the core of any nanophotonic device. Of particular interest are nanophotonic particle accelerators that promise a compact alternative to conventional radiofrequency-based accelerators. Efficient electron acceleration in such compact devices critically depends on achieving nanometer control of electron trajectories by precisely designed optical nearfields inside the device. However, these nearfields have so far been inaccessible due to the complexity of the devices and their geometrical constraints, hampering efforts to design and optimize future nanophotonic particle accelerators. Here we present the first measurement of the field distribution inside a nanophotonic accelerator. We develop a novel microscopy approach based on photon-induced nearfield electron microscopy (PINEM) to achieve frequency-tunable deep-subwavelength imaging of the nearfield inside nanophotonic accelerators. We compare the two leading designs of nanophotonic accelerators, also known as dielectric laser accelerators (DLAs): a dual-pillar structure with distributed Bragg reflector and an inverse-designed resonant structure. Our experiments are complemented by full 3D simulations, unveiling surprising deviations from the expected designs, showing complex field distributions related to intricate 3D features in the device and its fabrication tolerances. We further envision a tomography method to image the 3D field distribution, key for the future development of high-precision and hence high-efficiency DLA devices as well as other nanophotonic devices.

description: Adiabatic subtraction is a popular method of renormalization of observables in quantum field theories on a curved spacetime. When applied to the computation of the power spectra of light ($m\ll H$) fields on de Sitter space with flat Friedmann-Lemaître-Robertson-Walker slices, the standard prescriptions of adiabatic subtraction, traceable back to Parker's work, lead to results that are significantly different from the standard predictions of inflation not only in the ultraviolet ($k\gg aH$) but also at intermediate ($m\ll k/a\lesssim H$) wavelengths. In this paper we review those results and we contrast them with the power spectra obtained using an alternative prescription for adiabatic subtraction applied to quantum field theoretical systems by Dabrowski and Dunne. This prescription eliminates the intermediate-wavelength effects of renormalization that are found when using the standard one.

description: A generic search for resonances is performed with events containing a $Z$ boson with transverse momentum greater than 100 GeV, decaying into $e^+e^-$ or $μ^+μ^-$. The analysed data collected with the ATLAS detector in proton-proton collisions at a centre-of-mass energy of 13 TeV at the Large Hadron Collider correspond to an integrated luminosity of 139 fb$^{-1}$. Two invariant mass distributions are examined for a localised excess relative to the expected Standard Model background in six independent event categories (and their inclusive sum) to increase the sensitivity. No significant excess is observed. Exclusion limits at 95% confidence level are derived for two cases: a model-independent interpretation of Gaussian-shaped resonances with the mass width between 3% and 10% of the resonance mass, and a specific heavy vector triplet model with the decay mode $W'\to ZW \to \ell\ell qq$.

description: Abstract Introduction: Ethiopia is the main endemic focus of louse borne relapsing fever. Borrelia recurrent is the etiologic agent for louse-borne relapsing fever and occurs as epidemic under conditions of poor socioeconomic status, overcrowding, poverty, draught and famine. Therefore, the aim of investigation was to investigate the occurrence outbreak of relapsing fever, identify the risk factors and suggest practical control measures to alleviate the disease burden of the community. Methods: We conducted facility based unmatched case control study to investigate the outbreak. All patients from 3 January to 29 January 2018 were included. fifty patients un matched with hundred controls that had no previous history of relapsing fever and admitted to for other case in the facility. Study was conducted in on a daily basis and data was analyzed using Microsoft Excel and Epi-Info version 7.2.0.1. Results: Among all confirmed patients 100% (50), was male. There was no death during the outbreak. Mean age of case and control was 26,31 years respectively and their median age was 24,32 years respectively. Statistically significant associations were Mass sleeping (AOR = 6.2, 95% CI [2.02-19.06]), who did not change cloth at night (AOR = 8.8, 95%CI [1.5-50.8]) and residency status at street (AOR = 26.4, 95%CI [4.79-145.5]) and residency status at daily bed room (AOR=48.2,95%CI [7.5-83] showed a statistically significant association. Those Not changing cloth at night was about eight times, Mass sleeping was six times, residency status on street was about twenty-six times and residency status on daily bed room was about forty-eight times likely hood of acquiring relapsing fever compare to those who change cloth at night, who did not sleep in mass and not sleeping in street and daily bed room. Conclusion: Among all case mass sleeping in street, daily bed room and lack of alternative clothes change at night were source and risk factor for the outbreak. Education on the transmission of Relapsing Fever was given to homeless and daily laborer people. The outbreak was contained due to prompt interventions taken and strong preventive measures were recommended to prevent emergence of future outbreak of relapsing fever.

description: This thesis examines doctors’ medical negligence and contingent criminal liability during the covid-19 pandemic. In particular, this study analysed medical act, medical malpractice and medical liability (by act or omission) concepts in association with all types of negligence. We also highlighted the lack of a legislative framework in the medical liability field. Moreover, in this study, I refer to patients’ statutory and constitutional rights that arise from the Constitution of Greece as well as International Conventions (right to life, absolute respect of dignity and protection against overt or implicit discrimination in the delivery of health services). I also analysed bioethical challenges engendered by the covid-19 pandemic putting emphasis on medical malpractice. Additionally, a literature review was carried out that revealed telemedicine’s value, especially during the covid-19 pandemic. I again highlighted the lack of a relevant legislative framework. Finally, the screening criteria in intensive care during the covid-19 pandemic, as well as the case of concealment of ventilators in Italy, were mentioned, and the cost-benefit ratio of treatments or interventions in Oncology and Ophthalmology in relation to the risk of SARS-CoV infection was examined.

description: Diese Arbeit analysiert, wie das Public Utility Vehicle Modernization Program (PUVMP) den öffentlichen Personenverkehr und insbesondere die bisher lose organisierten Jeepneys im hoch urbanisierten Raum der Metro Manila zu modernisieren und zu rationalisieren versucht. Ausgehend von der Annahme, dass (1) heutige (urbane) Entwicklungsprogramme meist neoliberalen Logiken folgen und dass (2) Neoliberalismus nach gouvernementalem Ansatz als ein gesellschaftliches Projekt zur Neuordnung von Machtstrukturen zu verstehen ist und dem Machterhalt sowie der Machterweiterung politökonomischer Eliten dient, untersucht diese Arbeit das PUVMP nach Merkmalen des Inklusiven Neoliberalismus nach Craig und Porter (2006). Konkret stellt diese Arbeit heraus, warum und inwiefern das PUVMP beispielhaft für ein urbanes Entwicklungsprogramm in einem Staat des globalen Südens als neoliberal zu gelten hat, wie es auf das neoliberale Imaginary der Global City rekurriert, wie sich eine solche neoliberale Agenda gesellschaftlich auswirken kann. Schließlich zeigt es, warum diese Entwicklung letztlich zu Formen der sogenannten Inclusion Delusion führt.
description: This paper focuses on the question of how the Public Utility Vehicle Modernization Program (PUVMP) seeks to modernize and rationalize the previously loosely organized jeepneys in the highly urbanized area of Metro Manila. Based on the premise that (1) most (urban) development programs follow neoliberal thought and (2) adopting a Foucauldian approach on neoliberalism, understanding it as a societal project reorganizing power structures to consolidate and extend the power of polit-economical elites, this paper applies Craig and Porter’s theory of ‘inclusive neoliberalism’ (2006) on the PUVMP. More specifically, this paper aims to show to what extent the PUVMP proves to be driven by neoliberal logic, especially in following the neoliberal imaginary of a ‘Global City’, how this can affect society and social inequality, and, ultimately, can lead to an excluding phenomenon called ‘inclusion delusion’.

description: In nuclear reaction experiments, the measured decay energy spectra can give insights into the shell structure of decaying systems. However, extracting the underlying physics from the measurements is challenging due to detector resolution and acceptance effects. The Richardson-Lucy (RL) algorithm, a deblurring method that is commonly used in optics and has proven to be a successful technique for restoring images, was applied to our experimental nuclear physics data. The only inputs to the method are the observed energy spectrum and the detector's response matrix also known as the transfer matrix. We demonstrate that the technique can help access information about the shell structure of particle-unbound systems from the measured decay energy spectrum that isn't immediately accessible via traditional approaches such as chi-square fitting. For a similar purpose, we developed a machine learning model that uses a deep neural network (DNN) classifier to identify resonance states from the measured decay energy spectrum. We tested the performance of both methods on simulated data and experimental measurements. Then, we applied both algorithms to the decay energy spectrum of $^{26}\mathrm{O} \rightarrow ^{24}\mathrm{O}$ + n + n measured via invariant mass spectroscopy. The resonance states restored using the RL algorithm to deblur the measured decay energy spectrum agree with those found by the DNN classifier. Both deblurring and DNN approaches suggest that the raw decay energy spectrum of $^{26}\mathrm{O}$ exhibits three peaks at approximately 0.15~MeV, 1.50~MeV, and 5.00~MeV, with half-widths of 0.29~MeV, 0.80~MeV, and 1.85~MeV, respectively.

description: The central role of Value-at-Risk (VaR) within bank market risk regulation received signifcant criticism from fnancial media and government investigations into the events of the 2007–2009 fnancial crisis. Impending reform of bank market risk regulation under the Fundamental Review of the Trading Book (FRTB) demotes VaR, replacing it with a layered framework centred on expected shortfall (ES). However, many of these criticisms assume full integration of internal and regulatory market risk models and further, a linear relationship between risk models and regulatory capital. We examine bank practitioners’ perspectives and experienced realities to better understand the operational relationship between internal and regulatory market risk models, and between risk models and capital. This has important policy implications for the efficacy of the reforms to banking regulation, fnancial stability and navigating the dichotomy of private and public interests.

Assessment of association between Sleep quality and Overweight/Obesity among adults in Addis Ababa, Ethiopia
Creators: name: Shemsu, Muna
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Background: - Worldwide an estimated 35.8 million (2.3%) of global Disability Adjusted Life Years are caused by overweight and obesity. Emerging evidence suggests that the contribution of factors such as sleep quantity and quality to obesity need to be studied in detail as sleep disturbance could contribute to alterations in energy balance. Yet the majority of the evidence on this topic is from wealthy nations, and remains poorly understood in developing countries including Ethiopia. Objective: - The main aim of this study was to determine the relationship between overweight/obesity and sleep quality among adult population in Addis Ababa, Ethiopia. Methods: - A community based cross-sectional study was conducted on 575 adults who were residents of Addis Ababa. Multi stage sampling method was employed to select the study participants. Data on socio-demographic characteristics and anthropometric measurements were collected. A validated Pittsburgh Sleep Quality Index (PSQI) and Global Physical Activity Questionnaire were used to evaluate sleep quality and physical activity of study participants. Depression was assessed with Patient Health Questionnaire-9. Qualitative Food frequency questionnaire and eating habit questionnaire were used for dietary assessment. Sleep quality was categorized in to poor and good based on global PSQI score. Body mass index was computed using weight and height (Kg/m 2 ). Bivariate and multivariate logistic regression analysis was employed to see association between sleep quality and other covariates with overweight/obesity. Result: - A total of 548 adults were involved in this study and 161 (29.4%) of them were overweight/obese. A total of 177 (32.3%) respondents had poor sleep quality. After adjusting for multiple factors, we found that sleep quality was associated with being overweight/obese. Specifically, the odds of being overweight/obese were 3.8 times higher among adults with poor sleep quality [AOR 3.83: 95% CI: 2.33- 6.29] than the odds among adults with good sleep quality. Conclusion and recommendation This study documented a considerable prevalence of overweight/obesity and poor sleep quality among adults in Addis Ababa and further showed a significant association between sleep quality and overweight/obesity. Therefore health promotion programs targeting established risk factors for poor sleep quality are needed. In addition to this, improvements in sleep habits should be considered as part of intervention to prevent obesity.

description: Articulations of vulnerability, of the will to address the challenges posed by climate change, and of criticism of the international community’s inadequate efforts to limit global warming have taken many forms. In the Central Pacific atoll nation of Kiribati, songs associated with emotions are one of the artistic forms used to convey these articulations. In this paper, we turn our attention to a song about climate change that was written in English to reach the global community. We argue that this song, with its highly articulated and evoked emotions, represents a political practice in which the agency of atoll inhabitants is expressed. This song allows the protest against international climate policies to be heard and felt on the global stage. Although Kiribati is considered particularly vulnerable, the composer resists portraying the nation as a victim of climate change. Instead, he emphasizes the people’s agency and calls on the global community to take appropriate action.

In this work, we have simulated the optical properties of one-dimensional photonic structures, i.e. photonic crystals and microcavities, in which few-layer black phosphorus is one of the components. The insertion of the 5 nm black phosphorous layers leads to a photonic band gap in the photonic crystals and a cavity mode in the microcavity interesting for light manipulation and emission enhancement.

description: In der vorliegenden Arbeit wurden Rauschanalysen bei dem induktiv gekoppelten Plasma (ICP), dem kapazitiv gekoppelten Plasma (CMP) und dem mikrowelleninduzierten Plasma (MIP) aufgenommen. Rauschanalysen sind in der optischen Emissionsspektrometrie geeignete Mittel, mit deren Hilfe man Störungen durch unterschiedliche Quellen, wie z.B. Probenzuführungssyteme, aufdecken kann. Mit ihrer Hilfe ist es möglich, gezielt Verbesserungen durchzuführen wie z.B der mit einem analytischen Verfahren erreichbaren Präzision. Da in der optischen Emissionsspektrometrie mit einem Plasma als Anregungsquelle Probenzuführungssysteme die größten Rauschquellen darstellen, wurden gezielt im Fall des ICPs und CMPs pneumatische Zerstäubersysteme, bestehend aus peristaltischer Pumpe, Zerstäuber und Zerstäuberkammer, sowohl im Betrieb mit wäßrigen als auch organischen Lösungen, untersucht. Deutliche Unterschiede zwischen den einzelnen Zerstäubern und den dazugehörigen Zerstäuberkammern konnten festgemacht werden. Da die größten Störungen durch die Pulsation der peristaltischen Pumpe verursacht werden, wurden ebenfalls auch verschiedene Pumpensysteme untersucht. Abhängigkeiten konnten nicht nur auf Probenzuführungssyteme sondern auch auf den in der Lösung vorhandenen Gesamtsalzgehalt aufgezeigt werden. Rauschanalysen am MIP wurden im Zusammenhang mit dessen Betrieb mit einer neuartigen elektrochemischen Hydriderzeugung durchgeführt. Eine praktische Anwendung von Rauschanalysen wurde aufgezeigt bei der Auswahl eines geeigneten Zerstäubersystems für die Bestimmung von Elementen in weichmagnetischen Legierungen sowie bei der Adaption geeigneter Analysenbedingungen im Fall des stabilen Betrieb eines ICPs mit organischen Lösungen. Der stabile Betrieb eines ICP mit organischen Lösungen mußte gewährleistet werden, da in einem weiteren Teil dieser Arbeit mit Hilfe eines "online"-Verfahrens eine Abtrennung von Zirkon aus Zirkondioxidkeramiken in organischen Lösungen durchgeführt wurde. Die Abtrennung erfolgte durch die spezifische Komplexion des Zirkons mit Hilfe des Komplexbildners Theonyltrifluoroaceton und anschließender Fixierung des Komplexes auf einer Mikrosäule, die mit einem oberflächenmodifizierten Silikagel (Reversed Phase-18), gefüllt war. Die Abtrennung des sehr linienreichen Matrixelementes Zirkon führte zu einer deutlichen Vereinfachung der Bestimmung der Elementspuren Magnesium, Mangan und Yttrium, bei denen die Bestimmung der jeweiligen Konzentration mit Hilfe des ICPs erfolgte. Die Nachweisgrenzen für diese drei Elemente konnten deutlich gegenüber dem früher angewandten Verfahren mit der Flammenatomabsorptionspektrometrie (FAAS) verbessert werden.

description: Background: In Ethiopia, despite the increasing availability of Insecticidal Treated Nets (ITNs); its use among net owning households has not been satisfactory. Hence, in addition to scaling up ITNs distribution, periodic assessment of the utilization and associated factors among high risk population is highly recommended. Objective: The objective was to assess level of Insecticide Treated Net utilization and associated factors among under-five children and household net ownership in Adami Tullu District, Oromia Region, Ethiopia. Methods: A community based cross sectional study was conducted in Adami Tullu district from February 10-20, 2014. Data was collected using structured questionnaire and observation checklist. Focus Group Discussions were conducted. Cluster random sampling technique was used to select the study units. Bivariate logistic regression was applied for the analysis of each of the independent variables against ITN utilization among under five children and household net ownership. Those significant variables were entered into model to determine independent predictors of both outcome variables. Results: Household ownership of at least one ITN was 25.3%. The indoor residual spray (IRS) coverage was 97.0%. ITN utilization among under-five children was 63.9% for those owning at least one ITN. Awareness of sleeping under net every night prevents malaria [AOR (95%CI) =4.7 (1.1-9.6)], spouse education [AOR (95%CI) =1.74 (1.2-2.6)], and kebeles (i.e. Boccessa [AOR (95%CI) =2.2 (1.2-4.1)], Elka Chellemo [AOR (95%CI) =2.3(1.2-4.4)]) were the independent predictors of the ITNs ownership. While, ITN utilization among under-five children was affected by knowledge of ITN kills malaria mosquitoes [AOR (95%CI) =3.8 (1.15-12.4), knowing fever as a symptom of malaria [AOR (95%CI) =3.2(1.05-9.6)] and gender of the child [AOR (95%CI) =6.0 (2.5-12.8). Qualitative result found lack of understanding, fear of side effect and misuse of the nets as the main barriers of ITN use. Conclusion and Recommendation: Even though the indoor residual spray coverage reached the national target (90%), the ownership of ITNs and the utilization among high risk population remained far from 2015 target of universal coverage and 80% utilization. Information, Education and Communication (IEC) on the ITN utilization need to address misconception regarding durability of ITNs and focus on avoiding gender discrimination among under-five child

description: In this work, the properties of the method of clustering of variables around latent components (CLV) are investigated. A statistical model is postulated. This model is especially appropriate for sensory profiling data. It sheds more light on the method CLV. The clustering criterion can be expressed in terms of the parameters of the model. It is shown that, under weak conditions, the hierarchical algorithm of CLV finds the correct partition while the partitioning algorithm depends on the partition used as a starting point. Furthermore, the performance of CLV on the basis of a sample is investigated by means of a simulation study. It is shown that this performance is comparable to the performance of known methods such as the procedure Varclus of the software SAS. Finally, two methods for determining the number of groups are proposed and compared.

description: We investigate the tunneling magnetoresistance (TMR) effect using the lattice models which describe the magnetic tunnel junctions (MTJ). First, taking a conventional ferromagnetic MTJ as an example, we show that the product of the local density of states (LDOS) at the center of the barrier traces the TMR effect qualitatively. The LDOS inside the barrier has the information on the electrodes and the electron tunneling through the barrier, which enables us to easily evaluate the tunneling conductance more precisely than the conventional Julliere's picture. We then apply this method to the MTJs with collinear ferrimagnets and antiferromagnets. We find that the TMR effect in the ferrimagnetic and antiferromagnetic MTJs changes depending on the interfacial magnetic structures originating from the sublattice structure, which can also be captured by the LDOS. Our findings will reduce the computational cost for the qualitative evaluation of the TMR effect, and be useful for a broader search for the materials which work as the TMR devices showing high performance.

description: Experiences of loss and change following acquired brain injury (ABI) are frequent and multi-contextual, yet the long-term experiences of people with ABI are not well understood. This study explored the experiences of intrapersonal loss, grief and change in people with ABI, a decade after their injury. Twelve adults with ABI were interviewed 10–13 years post-injury. Using interpretative phenomenological analysis, we identified four overarching themes: a dawning realization of the impact of injury; loss of personhood; loss and liminality; and learning to live with loss and grief. Our findings indicate that in the decade following ABI, people continue to develop awareness of the impact of their injury and experience oscillating acceptance towards enforced changes. Participants reported a diminished sense of agency and autonomy in how they were perceived by and interacted with following injury. Additionally, identity may be lost, suspended, and renegotiated. Findings suggest dynamic, active, and flexible coping strategies that continue to be present over the long term. Considering the persistent nature of the injury and the evolving needs of the individual, a longer term view of rehabilitation outcomes may be required, contextualised by relational and intrapersonal challenges that may present over the longer term.

description: We show that a large class of fermionic theories are dual to a $q \to 0$ limit of the Potts model in the presence of a magnetic field. These can be described using a statistical model of random forests on a graph, generalizing the (unrooted) random forest description of the Potts model with only nearest neighbor interactions. We then apply this to find a statistical description of a recently introduced family of $OSp(1|2M)$ invariant field theories that provide a UV completion to sigma models with the same symmetry.

description: Highlighting the importance of literature in the EFL setting is what this portfolio primarily focuses on, taking into account its numerous benefits. In detail, it is designed to contribute to students’ personal growth, boost creativity and imagination, promote critical thinking and active participation, offer an alternative learning experience and ultimately foster language acquisition. For this reason, Roald Dahl’s The Witches was selected and five teaching sessions were designed to draw attention to the issue of the generation gap and how adults and teenagers can find ways to overcome their differences. These lessons proved to be very constructive as learners understood the use of the word witch as a metaphor for power and authority, created their own imaginary witches, made personal connections, reflected on the differences between adults and teenagers and used logical arguments to deal with conflicts. Most importantly, they realized that learning can be both entertaining and relevant to their own personal interests.
description: Η ανάδειξη της σημασίας της λογοτεχνίας στο πλαίσιο εκμάθησης της Αγγλικής γλώσσας είναι αυτό στο οποίο εστιάζει πρωτίστως αυτό το χαρτοφυλάκιο, λαμβάνοντας υπόψη τα πολυάριθμα οφέλη της. Αναλυτικά, έχει σχεδιαστεί για να συμβάλλει στην προσωπική ανάπτυξη των μαθητών, να τονώσει τη δημιουργικότητα και τη φαντασία, να προωθήσει την κριτική σκέψη και την ενεργό συμμετοχή, να προσφέρει μια εναλλακτική μαθησιακή εμπειρία και τελικά να ενθαρρύνει την κατάκτηση της γλώσσας. Για αυτόν τον λόγο, επιλέχτηκε το βιβλίο «Οι Μάγισσες» του Roald Dahl και σχεδιάστηκαν πέντε διδακτικές συνεδρίες για να επιστήσουν την προσοχή στο ζήτημα του χάσματος των γενεών και στο πώς οι ενήλικες και οι έφηβοι μπορούν να βρουν τρόπους να ξεπεράσουν τις διαφορές τους. Αυτά τα μαθήματα αποδείχθηκαν πολύ εποικοδομητικά καθώς οι μαθητές κατάλαβαν τη χρήση της λέξης μάγισσα ως μεταφορά για τη δύναμη και την εξουσία, δημιούργησαν τις δικές τους φανταστικές μάγισσες, έκαναν προσωπικές συνδέσεις, προβληματίστηκαν για τις διαφορές μεταξύ ενηλίκων και εφήβων και χρησιμοποίησαν λογικά επιχειρήματα για να αντιμετωπίσουν συγκρούσεις . Το πιο σημαντικό, συνειδητοποίησαν ότι η μάθηση μπορεί να είναι και διασκεδαστική και σχετική με τα δικά τους προσωπικά ενδιαφέροντα.

description: The complex coupled short pulse equation (ccSPE) describes the propagation of ultra-short optical pulses in nonlinear birefringent fibers. The system admits a variety of vector soliton solutions: fundamental solitons, fundamental breathers, composite breathers (generic or non-generic), as well as so-called self-symmetric composite solitons. In this work, we use the dressing method and the Darboux matrices corresponding to the various types of solitons to investigate soliton interactions in the focusing ccSPE. The study combines refactorization problems on generators of certain rational loop groups, and long-time asymptotics of these generators, as well as the main refactorization theorem for the dressing factors which leads to the Yang-Baxter property for the refactorization map and the vector soliton interactions. Among the results obtained in this paper, we derive explicit formulas for the polarization shift of fundamental solitons which are the analog of the well-known formulas for the interaction of vector solitons in the Manakov system. Our study also reveals that upon interacting with a fundamental breather, a fundamental soliton becomes a fundamental breather and, conversely, that the interaction of two fundamental breathers generically yields two fundamental breathers with a polarization shifts, but may also result into a fundamental soliton and a fundamental breather. Explicit formulas for the coefficients that characterize the fundamental breathers, as well as for their polarization vectors are obtained. The interactions of other types of solitons are also derived and discussed in detail and illustrated with plots. New Yang-Baxter maps are obtained in the process.

Modellbasierte Effizienzanalyse grobgranularer rekonfigurierbarer Prozessorarchitekturen

description: Die vorliegende Arbeit befasst sich mit Analysemethoden für grobgranulare rekonfigurierbare Prozessorarchitekturen. Es wird ein modellbasiertes Verfahren vorgestellt, mit dessen Hilfe derartige Hardwarestrukturen auf einfache Weise bezüglich ihres Flächenbedarfs, der Datenrate und des Energieverbrauchs charakterisiert werden können. Weiterhin werden Untersuchungsergebnisse dargestellt, die einen Vergleich grobgranularer Architekturen mit anderen Implementierungsformen ermöglichen. Field-Programmable Gate-Arrays (FPGAs) stellen aufgrund der Rekonfigurierbarkeit auf Bitebene flexible Bausteine mit hoher Verarbeitungsgeschwindigkeit dar, allerdings auf Kosten eines enormen Flächenoverheads und hohen Energieverbrauches. Demgegenüber enthalten grobgranulare Architekturen komplexere, anwendungsspezifisch optimierte Datenpfade, die eine Rekonfigurierbarkeit auf Wortebene gestatten. Es ist ein parametrisierbares Modell für eine grobgranulare rekonfigurierbare Architektur entwickelt worden. Angenommen wird ein zweidimensionales Feld, dessen Basiszellen über lokale Datenleitungen, sowie über segmentierbare Busse miteinander kommunizieren können. Weiterhin sind auf lineare Algorithmen hin optimierte Prozessorelemente unterschiedlicher Komplexität entwickelt worden. Anhand von physikalischen Modellen zur Ermittlung des Flächenbedarfs, der maximalen Taktfrequenz und des Energieverbrauches werden die VLSI-Eigenschaften der Modelle abgeschätzt, und denen von FPGAs, DSPs und Semi-Custom-Entwürfen gegenübergestellt. Die Ergebnisse zeigen, dass grobgranulare Architekturen im Vergleich zu FPGAs je nach Implementierung eine 7 bis 20 mal höhere Flächen- und Energieeffizienz aufweisen. Die Datenrate beider Varianten liegt dabei etwa in der gleichen Größenordnung. Bei Abbildung von Algorithmen, für welche die grobgranularen Datenpfade nicht optimiert wurden, sinkt die Effizienz dagegen erwartungsgemäß deutlich ab.

description: This work develops a motion planner that compensates the deficiencies from perception modules by exploiting the reaction capabilities of a vehicle. The work analyzes present uncertainties and defines driving objectives together with constraints that ensure safety. The resulting problem is solved in real-time, in two distinct ways: first, with nonlinear optimization, and secondly, by framing it as a partially observable Markov decision process and approximating the solution with sampling.
Cosmic Ray Acceleration by a Versatile Family of Galactic Wind Termination Shocks

description: There are two distinct breaks in the cosmic ray (CR) spectrum: the so-called "knee" around $3 \times 10^{15}$ eV and the so-called "ankle" around $10^{18}$ eV. Diffusive shock acceleration (DSA) at supernova remnant (SNR) shock fronts is thought to accelerate galactic CRs to energies below the knee, while an extragalactic origin is presumed for CRs with energies beyond the ankle. CRs with energies between $3 \times 10^{15}$ and $10^{18}$ eV, which we dub the "shin," have an unknown origin. It has been proposed that DSA at galactic wind termination shocks, rather than at SNR shocks, may accelerate CRs to these energies. This paper uses the galactic wind model of Bustard et al. (2016) to analyze whether galactic wind termination shocks may accelerate CRs to shin energies within a reasonable acceleration time and whether such CRs can subsequently diffuse back to the galaxy. We argue for acceleration times on the order of 100 Myrs rather than a few billion years, as assumed in some previous works, and we discuss prospects for magnetic field amplification at the shock front. Ultimately, we generously assume that the magnetic field is amplified to equipartition. This formalism allows us to obtain analytic formulae, applicable to any wind model, for CR acceleration. Even with generous assumptions, we find that very high wind velocities are required to set up the necessary conditions for acceleration beyond $10^{17}$ eV. We also estimate the luminosities of CRs accelerated by outflow termination shocks, including estimates for the Milky Way wind.
