description: It was recently demonstrated that two machine-learning architectures, reservoir computing and time-delayed feed-forward neural networks, can be exploited for detecting the Earth's anomaly magnetic field immersed in overwhelming complex signals for magnetic navigation in a GPS-denied environment. The accuracy of the detected anomaly field corresponds to a positioning accuracy in the range of 10 to 40 meters. To increase the accuracy and reduce the uncertainty of weak signal detection as well as to directly obtain the position information, we exploit the machine-learning model of random forests that combines the output of multiple decision trees to give optimal values of the physical quantities of interest. In particular, from time-series data gathered from the cockpit of a flying airplane during various maneuvering stages, where strong background complex signals are caused by other elements of the Earth's magnetic field and the fields produced by the electronic systems in the cockpit, we demonstrate that the random-forest algorithm performs remarkably well in detecting the weak anomaly field and in filtering the position of the aircraft. With the aid of the conventional inertial navigation system, the positioning error can be reduced to less than 10 meters. We also find that, contrary to the conventional wisdom, the classic Tolles-Lawson model for calibrating and removing the magnetic field generated by the body of the aircraft is not necessary and may even be detrimental for the success of the random-forest method.

Behavior composition optimisation
Creators: name: Yadav, Nitin Kumar
Publisher: name: RMIT University
Year: 2024

description: The behavior composition problem involves automatic synthesis of a controller that is able to “realize” (i.e., implement) a desired target specification by suitably controlling a collection of already available, partially controllable, behaviors running in a partially predictable shared environment. A behavior in our context refers to an already existing functionality such as the logic of a device, a service, a standalone component, etc; whereas a target specification represents the desired non-existent functionality that is meant to be obtained through the available behaviors. Previous work in behavior composition has exclusively aimed at synthesising exact controllers, those that bring about the desired specification completely. One open issue has resisted principled solutions: if the target specification cannot be completely implemented, is there a way to realize it “optimally”? In this doctoral thesis, we propose qualitative and quantitative optimisation frameworks that are able to accommodate composition problems that do not admit the “perfect” coordinating controller. In the qualitative setting, we rely on the formal notion of simulation to define realizable fragments of a target specification and show the existence of a unique supremal realizable fragment for a given problem instance. In addition, we extend the qualitative framework by introducing exogenous uncontrollable events to represent observable contingencies. In the quantitative setting, we provide a decision theoretic approach to behavior composition by quantifying the uncertainties present in the domain. In all cases, we provide effective techniques to compute optimal solutions and study their computational properties.

description: Background: Most theories related to the attentional blink (AB), defined as the refractory period of 300 to 500 msecs following a conscious visual identification, during which a second detection task is impaired, argue that limitations of 'visual working memory' (VWM) underlie the phenomenon rather than suppression of attention. The current study examined the relationship between performance on an AB task and classical measures of visual and auditory memory and executive function (EF). Methods: Fifty-one adult volunteers completed the AB task but only 27 of these also completed an extensive battery of traditional measures of short-term and working memory, processing speed and EF. Correlation and regression methods were used to analyse the data. Results: Bivariate correlation showed a significant relationship between AB duration and non-verbal intelligence and processing speed. Multiple regression analysis demonstrated that four factors (non-verbal intelligence, letter-number sequencing, visual search and visuo-spatial recognition memory) explained 40 per cent of the variance, with better reasoning skills and letter-number sequencing associated with a shorter AB, and better visuo-spatial recognition memory associated with a longer AB. Conclusion: The positive beta weight in the model for visuo-spatial recognition memory may reflect that the ability to later recall a target depends on its depth of encoding. On the other hand, the negative betas in the regression model for verbal intelligence and processing speed indicate that AB duration may be a potentially useful measure of temporal rate of visual processing. Finally, the lack of any relationship between the AB and executive function performance measures used suggests that the mechanism of the AB is primarily confined to early sensory processing and lower level working memory. © 2007 Optometrists Association Australia.

description: Cet article étudie le lien entre la stabilité économique et la coopération internationale, en soulignant leur rôle central dans la promotion de la prospérité mondiale. Du côté positif, la stabilité économique, qui comprend une inflation maîtrisée, des taux de change stables et une croissance constante, favorise un environnement propice à l’investissement et à la création d’emplois. À l’inverse, la coopération internationale, en garantissant la synchronisation des politiques monétaires et budgétaires, en engageant des négociations commerciales et en faisant face aux crises économiques mondiales, renforce cette stabilité. Selon l’analyse théorique, lorsque les nations collaborent par le biais d’alliances économiques et commerciales, cela conduit à la croissance mondiale et contribue à prévenir les crises économiques. Cela souligne l’importance de la collaboration pour s’attaquer aux problèmes mondiaux tels que le changement climatique et la pauvreté. En conséquence, cette étude souligne le lien étroit entre ces deux facteurs pour parvenir à une prospérité durable à l’échelle mondiale.

DESIGN

description: In the frame of the development of ESA\'s Space Rider, the new European space transportation system, the conceptual design of the Descent Subsystem has been performed, laying the basis for the following development work of next design phases. The Descent System will be triggered at subsonic speed: a first phase of deceleration guaranteed by drogue parachute(s), a gliding parachute will be deployed and the controlled descent phase will begin. This solution will allow for a safe landing, reducing operating costs as well as recovery and refurbishment time of the vehicle. It is the first time that this kind of architecture for a descent subsystem is being developed in a major European space program and it is the most important space project with a gliding parachute since NASA\'s X-38, which was developed until 2001. The design of the Descent Subsystem poses a number of challenges, given the demanding requirements defined for this project: pinpoint landing, featured by low peak g-forces and thus low vertical landing speed. Additionally, strict requirements in terms of available space and power, maximum attainable weight and maximization of reliability and reusability complete the framework. In the phase A of the project a trade-off between different technical solutions has been carried-out by taking in account parameters such as development and recurring costs, readiness level of already available technologies, lead-time and heritage: two main possible architectures for the Descent Subsystem have been identified. The main difference between the two main solutions is the presence of a single reefed drogue parachute or the presence of two different drogues. In this study all the main equipment have been defined, and advantages and shortcomings coming from each solution critically analyzed. Critical areas to be further investigated have been identified to focus on in the next phases of design.

NUMERICAL SIMULATION

description: This work is a numerical and experimental study of fluid-structure interaction at Mach 5.8. Numerical results from low- and high-fidelity models are shown and compared. Procedures and details of the generation of the numerical mesh are given. The mesh topology shape, irrespective of flow direction, shock position, and sonic line location can lead to non-physical results if not optimised. Orthogonality of the cells to the wall is fundamentally important to reach numerical convergence and reliable results. Under an inviscid point of view, piston theory is confirmed to be an appropriate tool in the evaluation of the inviscid pressure over the plate, as it showed good agreement with the empirical data. Concerning the viscous aspects, the shear stress and heat transfer histories shared the same frequency with the structural, and their spatial distribution present a degree for hysteresis. Finally, the boundary layer height changes not only according to local slope and speed of the wall, but it is a function of the actual structural mode of vibration.

description: A forward-facing step (FFS) immersed in a subsonic boundary layer is studied through a high-order Flux Reconstruction (FR) method to highlight the flow transition induced by the step. The step height is a third of the local boundary-layer thickness. The Reynolds number based on the step height is 720. Inlet disturbances are introduced giving rise to streamwise vortices upstream of the step. It is observed that these small-scale streamwise structures interact with the step and hairpin vortices are quickly developed after the step leading to flow transition in the boundary layer.
title: Korpuslinguistische Untersuchung deutscher Intensivierer
Creators: name: Paar, Marie-Hedwig
Year: 2009

description: In dieser Arbeit geht es um die korpuslinguistische Untersuchung der Intensivierer (genauer gesagt: Gradadverbien): "enorm", "immens", "gewaltig", "äußerst", "außerordentlich", "außergewöhnlich", "unheimlich" und "unendlich". Diese Wörter habe ich vor allem mithilfe der Kookkurrenzdatenbank CCDB und der Software COSMAS II untersucht, die beide auf das Deutsche Referenzkorpus zugreifen (zugänglich über http://corpora.ids-mannheim.de/ccdb bzw. http://www.ids-mannheim.de/cosmas2). Zu jedem Wort erstellte ich dabei ein Profil, das zeigt, welche Adjektive oder Verben es am häufigsten und wahrscheinlichsten intensiviert. Wenn man diese Kookkurrenzprofile (kombinatorischen Profile) der einzelnen Intensivierer miteinander vergleicht, werden viele Gemeinsamkeiten und Unterschiede zwischen den Intensivierern offensichtlich. Manche zum Beispiel sind nur sehr schlecht geeignet, ein Verb zu intensivieren, wie es bei "äußerst" der Fall ist, bei "gewaltig" wiederum hat sich gezeigt, dass es zur Adjektiv-Intensivierung eigentlich nicht taugt beziehungsweise dabei sehr umgangssprachlich klingt. An den Profilen erkennt man auch, dass manche Intensivierer sehr viele verschiedene Operanden (=durch sie intensivierbare Wörter) haben, andere jedoch ziemlich eingeschränkt sind in ihren Kombinationsmöglichkeiten. Besonders interessant sind die Ergebnisse auch dann, wenn bestimmte Operanden nur bei einem einzigen Intensivierer auftreten – dadurch wird deutlich, dass es sich bei den Intensivierern nicht einfach um Synonyme handelt, die man jederzeit auswechseln könnte. Oft jedoch sind die Profile in gewissen Bereichen sehr ähnlich, beispielsweise passen die Operanden von "äußerst" fast immer auch zu "außerordentlich" – hier ist dann die Suche nach Beispielsätzen über COSMAS II besonders wichtig – denn dann lassen sich semantische Unterschiede besser erkennen und man kann mit Substitutionstests versuchen, einen bestimmten Intensivierer durch alle möglichen anderen zu ersetzen – um zu sehen, ob sich entweder die Bedeutung ein wenig ändert, der Austausch aus pragmatischen/ kombinatorischen Gründen nicht geht, oder ob es in gewissen Fällen tatsächlich keinerlei Unterschied macht, welcher Intensivierer verwendet wird. Auf diesem Weg konnte ich die Intensivierer auf den verschiedenen Ebenen gegeneinander abgrenzen und zeigen, dass sie zwar in gewissen Kontexten sehr ähnlich verwendbar sind, aber oft doch durch kleine Bedeutungsunterschiede zu trennen sind oder sich in ihrer Kombinatorik unterscheiden.

description: Flaky tests, characterized by their non-deterministic behavior, present significant challenges in software testing. These tests exhibit uncertain results, even when executed on unchanged code. In the context of industrial projects that widely adopt continuous integration, the impact of flaky tests becomes critical. With thousands of tests, a single flaky test can disrupt the entire build and release process, leading to delays in software deliveries. In our study, we conducted a systematic mapping to investigate tools related to flaky tests. From a pool of 37 research papers, we identified 30 tools specifically designed for detecting, mitigating, and repairing flakiness in automated tests. Our analysis provides an overview of these tools, highlighting their objectives, techniques, and approaches. Additionally, we delve into the highest-level characteristics of these tools, including the causes they address. Notably, approximately 46\% of the tools focus on tackling test order dependency issues, while a substantial majority (70\%) of the tools are analyzed in the context of the Java programming language. These findings serve as valuable insights for two key groups of stakeholders: (Software Testing Community:) Researchers and practitioners can leverage this knowledge to enhance their understanding of flaky tests and explore effective mitigation strategies; (Tool Developers:) The compilation of available tools offers a centralized resource for selecting appropriate solutions based on specific needs. By addressing flakiness, we aim to improve the reliability of automated testing, streamline development processes, and foster confidence in software quality.
The symbolic construction of the global imaginary in Sydney and Melbourne
Creators: name: Durante, Tommaso
Publisher: name: RMIT University
Year: 2024

description: Globalisation is mainly perceived and understood as an economic driven process. This study argues that an important aspect of this multidimensional process is that it is also a cultural and visual-ideological phenomenon. The 'global' pervades and alters the urban social fabric through media representations and it has the symbolic power to transform urban spaces by creating the 'global imaginary' in a single place. Although globalization scholarship as an 'objective' phenomenon is greatly expanded, so far not much attention has been paid to the feature of its 'subjective' dimension-the symbols, images and metaphors that suggest the common sense of the 'global'. In considering globalization as a material and ideational process, this exegesis carries out an investigation in the two major cities of Australia, Sydney and Melbourne, from an aesthetics of global change perspective and through a phenomenological-interpretative approach. Furthermore, through the lenses of social and political theory, this exegesis analyses and interprets a given body of visual images gathered in the two urban social fabrics under investigation and identified as 'condensation symbols' and ideological markers of globality. Located at the crossroads of global, urban and media studies, this subjective interpretative approach to the people's new public consciousness aims to grasp how the global imaginary is symbolically and socially produced. Yet these images are limited, selective and highly 'subjective' media representations of concepts associated with structures, places and identity; in this sense they are not unproblematic. However, they are crucial keys to access the 'global imaginary'. In visualising, analysing and interpreting change in Sydney and Melbourne, this study suggests that the two cities show an increasing production, circulation and consumption of visual formations that 'condense' hybrid spatial-symbolic scales of the 'local-national' and the 'global'. Indeed, this investigation reveals that the two cities display a fragmented ideological landscape in which the local-national appears increasingly mediated and sustained by the global in a process that sees the symbolical power of the global eventually reinforced. Furthermore Asia appears to be the new globalizing cultural force in Australia. Associated with these dynamics there is a process of integration, fragmentation, re-composition and eventually of cultural hybridization that supports, suggests and sustains the symbolic construction of the global imaginary in Sydney and Melbourne. As a result, it can be also asserted that different forms of globality are possible.

description: Following the requirements for supersonic wind tunnel tests at high angles of attack, the capability to verify the high-angle-of-attack provisions in the T-38 wind tunnel of VTI was needed. Such task is conveniently performed by tests of a standard model. As the volume of reference data on standard models at high angles of attack was small, a series of tests of the HB-2 model at Mach numbers 1.5 to 4 and angles of attack up to 30 was performed to create a reference database for future tests. Results were successfully correlated to lower-angle-of-attack data from other facilities.

title: Die Hizbullah im Blickwinkel der libanesischen Printmedien
Creators: name: Müller-Funk, Lea Suzana
Year: 2010

description: Wie verschieden Realitäten in unterschiedlichen Umgebungen geschildert werden, ist eine der Kernfragen dieser Arbeit. Durch eine Medienanalyse der beiden momentan führenden Tageszeitungen des Libanons – an-Nahār und as-Safīr- wurde im Zeitraum des Libanonkrieges im Juli 2006 untersucht, wie die Hizbullah als medialer Interdiskurs entworfen wurde. Dabei wurden gewollt eine regierungsfreundliche und eine oppositionelle Zeitung gewählt, um zwei wichtige unterschiedliche Diskurspositionen im Libanon einzufangen. Durch einen an Siegfried Jäger, Jürgen Link und Ruth Wodak orientierten Diskursbegriff wurde das Zeitungsmaterial auf drei Hauptdiskursstränge untersucht: die Hizbullah, der Libanon und seine Beziehung zur Hizbullah und Israel als der „Feind“, als der „Andere“ im Konflikt. Dabei wurde vor allem auf die Legitimationsstrategien der einzelnen Akteure Wert gelegt. Trotz prinzipiell unterschiedlicher politischer Grundeinstellungen der beiden Zeitungen konnte eine gewisse Annäherung bezüglich der Berichterstattung über die Hizbullah im untersuchten Zeitraum festgestellt werden. Dabei scheint die Rolle der Hizbullah als Widerstandsbewegung gegen den immer wieder als „inhuman“ geschilderten Staat Israel im Mittelpunkt zu stehen, während das schiitisch-islamistische Element der Hizbullah ausgeblendet wird. Zudem bietet die Arbeit einen Abriss über die Entwicklung der Hizbullah im Libanon und einen kurzen Überblick über die Geschehnisse des Libanonkrieges 2006 und seinen Ausgang, sowie eine kurze theoretische Überlegung zum Begriff des Diskurses. Des weiteren findet sich in der Arbeit ein ausführliches Kapitel über die libanesische Presse selbst: ein genereller Überblick über die Entstehungsweise der libanesischen Presse, über ihre Leserschaft und die Leserdichte einzelner Zeitungen, ihre politische Orientierung und verschiedene verwendete Textsorten sollen einen Einblick über die Funktionsweise der libanesischen Presse vermitteln.

description: The development of a hybrid flight engine for a sounding rocket requires intensive preparation work and pretests. To obtain better understanding of the difficulties in design and operation that occur with LOX/HTPB rocket engines, four rocket engines with increasing size and thrust level are successively developed and manufactured. Listed chronologically, those engines are the demonstrator engine, the subscale engine with a cylindrical grain geometry and later a star shaped geometry, the full-scale test engine and the full-scale flight version. At first a small-scale technology demonstrator was developed. It produced a mean thrust of 160N for 5s and had the purpose to validate the design calculations and to gain first experiences with the use of cryogenic propellants, especially regarding cooldown procedures. Based on this test results the so-called sub-scale engine was developed and tested. The engine can be operated with two grain configurations, using either a cylindrical grain or a star shaped grain. The star shaped grain geometries are realized, using an additive manufactured core, outside of which the HTPB is casted. In the low thrust configuration, the engine is operated using a cylindrical single port HTPB grain and it produces a thrust of about 540 N for a duration of 10 s. In the high thrust configuration, the engine is operated using a star shaped HTPB grain and delivers a thrust of 1600 N, with an operation time of 5 s. This grain geometry is a downscaled version of the actual full-scale grain geometry, which provides the opportunity to gain insight on the regression behavior and to validate and improve the performance calculations. The test engines are built in a differential design, so various injector types, as well as preand post- combustion chamber geometries can easily be tested. The nozzle segment can be exchanged in order to find a nozzle design that can withstand the hot exhaust gases, while still remaining lightweight. The next development step is the design of the 10 kN full-scale test engine, which shows the same combustion and performance characteristics as the flight version, but is designed with very high safety margins. The results from this test campaign will be used to build a high performance and lightweight 10 kN LOX/HTPB engine which will power the Warr-Ex3 rocket, the largest sounding rocket ever planned by the WARR (Wissenschaftliche Arbeitsgemeinschaft  fur Raketentechnik und Raumfahrt) student rocketry group. This study will discuss the design, construction and testing of the sub-scale engines, as well as the subsequent design decisions that went into the development of the full-scale engine.

description: Disc winds and planet-disc interactions are two crucial mechanisms that define the structure, evolution and dispersal of protoplanetary discs. While winds are capable of removing material from discs, eventually leading to their dispersal, massive planets can shape their disc by creating sub-structures such as gaps and spiral arms. We study the interplay between an X-ray photoevaporative disc wind and the substructures generated due to planet-disc interactions to determine how their mutual interactions affect the disc's and the planet's evolution. We perform three-dimensional hydrodynamic simulations of viscous ($α= 6.9\cdot10^{-4}$) discs that host a Jupiter-like planet and undergo X-ray photoevaporation. We trace the gas flows within the disc and wind and measure the accretion rate onto the planet, as well as the gravitational torque that is acting on it. Our results show that the planetary gap takes away the wind's pressure support, allowing wind material to fall back into the gap. This opens new pathways for material from the inner disc (and part of the outer disc) to be redistributed through the wind towards the gap. Consequently, the gap becomes shallower, and the flow of mass across the gap in both directions is significantly increased, as well as the planet's mass-accretion rate (by factors $\approx 5$ and $\approx 2$, respectively). Moreover, the wind-driven redistribution results in a denser inner disc and less dense outer disc, which, combined with the recycling of a significant portion of the inner wind, leads to longer lifetimes of the inner disc, contrary to the expectation in a planet-induced photoevaporation (PIPE) scenario that has been proposed in the past.

description: We aim to provide a detailed characterization of near-infrared spectra for young LT brown dwarfs, including robust spectral typing, calibrating spectral indices, identifying possible binaries, and selecting suitable spectral standards. We processed and analyzed archival spectra from VLT/X-shooter for a sample of 56 dwarfs with ages between 10 and 600 Myr and spectral types between late-M and mid-T. We re-determine spectral types by comparing them with a set of literature templates and assess a large range of spectral indices, calibrated using a specifically designed literature sample. We are able to identify 15 spectral indices that are useful for spectral typing for specific spectral ranges discussed here and provide the scaling relations with spectral types. Moreover, we also identify 6 spectral indices which can be used to separate young L dwarfs from the field ones. The equivalent-widths of the alkali lines show a correlation with age, increasing towards the objects with higher surface gravity. From our sample, we confirm 3 that are likely to be binaries by their anomalous spectra that appear to be better fitted by a combination of spectral types. Finally, we identify 12 objects as preliminary near-infrared spectral standards for young LT dwarfs. This paper presents a significant step toward understanding the spectral sequence and properties of young L and T dwarfs. The relations and standards provided here will be useful for future spectroscopic work on young brown dwarfs and giant planets.

title: Die Bürgerrechtsbewegung in den USA
Creators: name: Krones, Christoph-Mathias

description: Die schwarze Bevölkerung der Vereinigten Staaten musste über Jahrhunderte hinweg Unterdrückung und Diskriminierung ertragen. Zunächst wurden Schwarze als Sklaven gehalten, dann durch rassistische Gesetzte von den Weißen getrennt. Es dauerte bis in die Mitte des 20. Jahrhunderts, bis sich ihr aufgestauter Frust entladen konnte. Die Afroamerikaner erkämpften ihre Rechte in den 50er Jahren vorerst noch vor Gerichten. Inspiriert durch Rosa Parks und Martin Luther King, Jr. wurde der Kampf um Gleichberechtigung in den 60er Jahren auf den Strassen fortgesetzt. Dies führte zur größten und erfolgreichsten, aber vor allem friedlichsten Bürgerrechtsbewegung der Geschichte der USA. Vierzig Jahre nach dem Ende dieser Bewegung ist ein Afroamerikaner Präsident der Vereinigten Staaten. Der beschwerliche Weg von der Sklaverei ins Weiße Haus wird in dieser Diplomarbeit dargestellt.

description: Auxiliary and Ground Power Units are major sources of noise and pollution at airports. Aachen University of Applied Sciences researches low-emission combustion of hydrogen and has developed the Micromix technology with proven low emission properties. The paper presents the exhaust gas and noise emission analysis comparing kerosene with MMX hydrogen combustion in the GTCP 36-300. The MMX combustor with hydrogen reduces the exhaust gas emissions significantly. The overall noise of the core engine is reduced, too, with higher sound-pressure-level magnitudes in the frequency range between 1000 Hz and 5000 Hz, the range most sensitive in human hearing.

description: In recent years the gas kinematics probed by molecular lines detected with ALMA has opened a new window to study protoplanetary disks. High spatial and spectral resolution observations have revealed the complexity of protoplanetary disk structure and correctly interpreting these data allow us to gain a better comprehension of the planet formation process. We investigate the impact of thermal stratification on the azimuthal velocity of protoplanetary disks. High resolution gas observations are showing velocity differences between CO isotopologues, which cannot be adequately explained with vertically isothermal models. The aim of this work is to determine whether a stratified model can explain this discrepancy. We analytically solve the hydrostatic equilibrium for a stratified disk and we derive the azimuthal velocity. We test the model with SPH numerical simulations and then we use it to fit for star mass, disk mass and scale radius of the sources in the MAPS sample. In particular, we use 12CO and 13CO datacubes.

Phase Detection in Medical Context: Overview and Outlook
Creators: name: Philipp, Patrick
Publisher: name: Karlsruhe
Year: 2018

description: To provide assistance functions, e.g. in context of surgical interventions, the use of a phase detection plays an important role. For instance, by assessing the progress of an on-going surgery, a tailored (i.e. context sensitive) decision support for medical practitioners can be carried out. The optimization of a workflow, e.g. by comparing recorded data with a predefined target model, is another application example. Subsequently, a phase detection provides opportunities to prevent errors, injuries, negligence or malpractices in the medical context. In this work, an overview of notable model approaches for a phase detection in medical context is presented. Based on this, further suggestions for future models are proposed.

description: In this paper, we have explored the observed matter-antimatter asymmetry in the Universe to constrain the model parameters in extended symmetric teleparallel gravity (STG) or $f(Q,T)$ gravity, where $Q$ be the nonmetricity and $T$ be the trace of energy momentum tensor. We have considered two functional forms of $f(Q,T)$ to find the baryon asymmetry to entropy ratio calculated at a decoupling temperature. Two different data sets namely Hubble data set and the Hubble+BAO+Pantheon data sets are used to constrain the scale factor and the constrained model is used to obtain the baryon asymmetry to entropy ratio. It is observed that, model constrained from the Hubble data set favour a narrow range of the $f(Q,T)$ gravity parameters to reproduce the observed baryon asymmetry.

LS3: Latent Semantic Analysis-based Similarity Search for Process Models
Creators: name: Schoknecht, Andreas

description: Large process model collections in use today contain hundreds or even thousands of conceptual process models. Search  functionalities can help in handling such large collections for purposes such as duplicate detection or reuse of models. One popular stream of search functionalities is similarity-based search which utilizes similarity measures for finding similar models in a large collection. Most of these approaches base on an underlying alignment between the activities of the compared process models. Yet, such an alignment seems to be quite difficult to achieve according to the results of the Process Model Matching contests conducted in recent years. Therefore, the Latent Semantic Analysis-based Similarity Search (LS3) technique presented in this article does not rely on such an alignment, but uses a Latent Semantic Analysis-based similarity measure for retrieving similar models. An evaluation with 138 real-life process models shows a strong performance in terms of Precision, Recall, F-Measure, R-Precision and Precision-at-k, thereby outperforming five other techniques for similarity-based search. Additionally, the run time of the LS3 query calculation is significantly faster than any of the other approaches.

description: Icing crystal icing is a severe problem for aviation as it can significantly affect the operation of engines and pitot probes. To reproduce such conditions for fundamental research inside an icing wind tunnel environment is challenging. Here, we summarize our efforts of the last five years to upgrade the Braunschweig Icing Wind Tunnel with ice crystal capability and we present both macroscopic and microscopic observations that reveal some of the underlying physical phenomena.

description: This paper uses various forecasting methods to forecast future crop production levels using time series data for four major crops in Pakistan: wheat, rice, cotton and pulses. These different forecasting methods are then assessed based on their out-of-sample forecast accuracies. We empirically compare three methods: BoxJenkins’ ARIMA, Dynamic Linear Models (DLM) and exponential smoothing. The best forecasting models are selected from each of the methods by applying them to various agricultural time series in order to demonstrate the usefulness of the models and the differences between them in an actual application. The forecasts obtained from the best selected exponential smoothing models are then compared with those obtained from the best selected classical Box-Jenkins ARIMA models and DLMs using various forecast accuracy measures.
