description: We use integral-field spectroscopy from the SAMI Galaxy Survey to identify galaxies that show evidence of recent quenching of star formation. The galaxies exhibit strong Balmer absorption in the absence of ongoing star formation in more than 10% of their spectra within the SAMI field of view. These Hd-strong (HDS) galaxies (HDSGs) are rare, making up only similar to 2% (25/1220) of galaxies with stellar mass log(M-*/M-circle dot) > 10. The HDSGs make up a significant fraction of nonpassive cluster galaxies (15%; 17/115) and a smaller fraction (2.0%; 8/387) of the nonpassive population in low-density environments. The majority (9/17) of cluster HDSGs show evidence of star formation at their centers, with the HDS regions found in the outer parts of the galaxy. Conversely, the HDS signal is more evenly spread across the galaxy for the majority (6/8) of HDSGs in low-density environments and is often associated with emission lines that are not due to star formation. We investigate the location of the HDSGs in the clusters, finding that they are exclusively within 0.6R(200) of the cluster center and have a significantly higher velocity dispersion relative to the cluster population. Comparing their distribution in projected phase space to those derived from cosmological simulations indicates that the cluster HDSGs are consistent with an infalling population that has entered the central 0.5r(200,3D) cluster region within the last similar to 1 Gyr. In the eight of nine cluster HDSGs with central star formation, the extent of star formation is consistent with that expected of outside-in quenching by ram pressure stripping. Our results indicate that the cluster HDSGs are currently being quenched by ram pressure stripping on their first passage through the cluster.

description: In the last few decades, the field of artificial vision has witnessed an overwhelming growth through academic research and increasing industry demands. One of the more exciting and promising developments in the field has taken form in the 3D vision paradigm. With the advent of 3D vision, the possibility to directly map in three dimensions the shape of an object has opened a wealth of new possibilities. The purpose of this work is to present the theory and design of a low-cost, portable and accurate 3D laser range scanning system. The system allows direct acquisition of 3D images from a scene. The proposed 3D imaging method uses a laser beam for measuring the distance to a target in a fixed point and computing its (X, Y, Z) coordinate in space. Through deflection of this beam using small motorized mirrors, a distant surface may be scanned into a full 3D range image. Unlike conventional ranging systems, the present design uses a single semiconductor laser diode serving as both a laser source and detector. Laser ranging is achieved through frequency modulation of the laser with time-of-flight coherent detection, based on the self-mixing effect in a laser diode. This allows for unambiguous range measurement capabilities over several meters. The benefits of this sensing approach over existing laser-based systems are numerous, and include: (1) Very low cost solution to the ranging problem. (2) No need for external optical sensing elements. (3) Coaxial source and detector configuration eliminates shadowing problems. (4) Coherent detection yields constant ranging error over useful workspace. (5) Velocity and range information available from a single measurement. (6) Interferometric scale measurements possible in fixed-frequency regime.

Being There: Travel Documentaries
Creators: name: Lopriore, Lucilla
Publisher: name: Iperstoria

description: The growing success of TV travel documentaries lies in this unusual way of travelling and in the fully engaging experience that its multimodal dimension offers. Travel documentaries have the power of nullifying time and space, making Star Trekian fictional teleportation possible; they are a powerful way of closing the gap between the viewing audience and distant tourist destinations. Thanks to the wide diffusion of technology and social networks these types of documentaries are more accessible by everyone everywhere. Derived from documentary films, travel documentaries have developed their own genre with specific features and organisation: a genre used by the tourist industry to persuade the target audience or by TV channels to sell tourist products ranging from videos to travel tours. Documentaries offer both the logic of immediacy and that of hypermediacy typical of remediation since they heighten the viewer’s experience of the event as authentic. This contribution illustrates how in the last two decades changes in travel documentary visual format, organisation and use of new technologies have re-mediated both their language, their information structure and their impact on universal audiences.

description: The critical peer review (CPR) of Life Cycle Assessment (LCA) studies is a task of value. The majority of benefits lie in the projects and are not realized from the outside. The effect to the outside concerns communication. A peer review can be conducted on various levels. As a measure of quality assurance and to assist the interpretation of results, it is already meaningful to ask some colleagues for their opinion. For credibility and reliability, external reviews are most suitable. The best option is to include interested parties, which will also support communication. Communication of LCA results need to be suitable for the respective target audience. Often results are over-interpreted or simplified too much. The publication of an assertion "A is better than B" is meaningless without some background information and some limitations of that statement. The background information and limitations are meaningless, if the target audience cannot understand them. © 2023 The Author(s), under exclusive license to Springer Nature Switzerland AG

Mediterraneità e bianchezza. Il razzismo italiano tra fascismo e articolazioni contempora nee (1861-2015)
Creators: name: Giuliani, Gaia
Publisher: name: Iperstoria
Year: 2020

description: In the wake on important research published in the last 15 years, this article aims to explore contemporary rearticulations of racial contructions of Italians as white and Mediterranean. It is founded on the idea that these constructions of whiteness and Mediterraneanness – where Mediterraneannes, as opposed to Aryanness, is a result of a complex conversion of historical and racial components in the discourse on Italians’ white identity – are a long-lasting and find their origins in the nation-building process. These constructions then underwent through important rearticulations in the reappraisal of the national identity and body politics during the Liberal Age, Fascism and finally the Republic. Through a methodology that intersects political philosophy, cultural, postcolonial and gender studies, the article investigates Mediterranean whiteness in current Italy as the result of a complex intertwining of Fascist legacies and postfascist dynamics. These legacies and dynamics include what I have called “symbolic anthropophagy” – drawing the concept from latin American decolonial and African-American feminist critiques – ideas of miscegenation and proximity/differences with the black race. These legacies and dynamics are interpreted contraputally in the context of the current rearticulations of race, gender and nation at the time of mass migrations and border control strategies.

"Notations of process of mind" in American poetry since 1945: Readings in Creeley, Whalen, Kerouac, and Ginsberg.

Subjects: subject: Literature, Modern.

description: This thesis examines the pursuit of forms derived from personal experience in (late-) modern American poetry, with a focus on four significant writers of the 1950s: Robert Creeley, Philip Whalen, Jack Kerouac, and Allen Ginsberg. The study begins with a brief overview of the theories that most profoundly influenced these writers: Ezra Pound's Imagism, William Carlos Williams' "Relative Measure," and Charles Olson's "Projective Verse." This overview raises a central issue in American letters, a belief first expressed by Emerson, in "The Poet," that inherited formulations cannot adequately reflect or represent the truly indigenous writer's experiencing of a living world. Pound, Williams, and Olson all experimented with open forms in an effort to document experience in its original energy. For the late-modern writers that centre this study, though, Paterson figures as the defining example of such experimentation, and provides a paradigm of the American poet's struggle to break free from the trammels of received, standard forms. A close study of this text reveals something of the aesthetic problems that the authentically American poet must overcome in order to make form new, the chief of these problems being the necessity to determine the place of tradition in contemporary writing. Readings in the four principal poets of immediate concern follow the commentary on Paterson. Each individual reading begins with an exploration of the author's poetics, indicating substantial connections with the theories of his main mentors or predecessors. Each of Creeley, Whalen, Kerouac, and Ginsberg has explicitly affirmed his belief that poetic form must not be preselected or predetermined, but shaped by the act of composition itself, from the needs of the poem at hand. A demonstration of the poet's theory-in-practice then follows, in the form of a close reading of a representative text from each author's production: Creeley's Hello: A Journal, February 29-May 3, 1976, Whalen's Scenes of Life at the Capital, Kerouac's San Francisco Blues, and Ginsberg's The Fall of America. As the postscript of this study indicates, the authors of these texts represent but a few of the participants in this major trend in American writing during the past fifty years. A brief overview of the theories, and some of the practice, of Paul Blackburn, Denise Levertov, Robert Duncan, Gary Snyder, and Amiri Baraka shows that Williams, Pound, and Olson influenced many contemporary American poets, and that this preference for personal forms is not isolated to a few of the perhaps more widely-recognized figures of twentieth-century American literature.

World Englishes and English as a Lingua Franca: Implications for Teacher Education and ELT
Creators: name: Vettorel, Paola
Publisher: name: Iperstoria
Year: 2020

description: The spread of English, first as a consequence of colonization and then of globalization processes, has brought to a diversification of Englishes. Rather than a monolithic language, connected solely to native Anglophone speakers, English has taken nowadays a plurality of forms, from Inner and Outer circle varieties to its lingua franca function as a means of communication among speakers of different L1s across the world. Furthermore, English increasingly constitutes a consistent presence in the out-of-school environment: younger generations in particular come into contact with Englishes in a variety of contexts, from the media to the linguistic landscape; all over Europe encounters with (linguistic) otherness are experienced starting from increasingly multicultural and multilingual school environments. This plurality has significant implications for ELT: first of all, awareness of the multifaceted realities of English ought to be promoted in teacher education to familiarize language educators with its implications in ELT, so that it can be acknowledged in classroom practices in order to prepare learners to be able to effectively communicate via English in its current plural dimension. This paper illustrates exemplifications of how WE- and ELF-informed activities can be incorporated into ELT classroom practices, drawing from two main datasets: lesson plans developed within university-run pre-service teacher education courses addressed at Italian secondary school English language trainee teachers (PAS/TFA), and from a project realized in three primary schools in Italy aimed at fostering awareness of English in the linguistic environment, of the plurality of English(es) and of its lingua franca role.

Female pair/dance figure skaters' self-reported attitudes, behaviors and perceptions related to weight loss.
Creators: name: Taylor, Gail M.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1998
Subjects: subject: Psychology, Social.

description: The purpose of this thesis was to examine the self-reported eating attitudes/behaviors behaviors, as well as weight loss pressures in female pair/dance figure skaters. Two separate studies were completed in order to examine these issues. Forty-one pair and dance female figure skaters (26 pairs, 15 dance) completed two questionnaires that tapped into whether the figure skaters exhibited disordered eating tendencies (EDI), and whether weight loss pressures were evident in this sporting population (SKATE Scale). Results from the EDI indicated that a significant number of the skaters had self-reported eating attitudes and behaviors analogous to individuals with disordered eating tendencies. Also, analyses of the SKATE Scale revealed that the figure skaters perceived themselves and their coach as the most significant sources of weight loss pressures, and that this pressure was mainly for performance benefits. Correlational analyses of the three most commonly used subscales of the EDI with the five pressure sources of the SKATE Scale revealed a strong positive relationship between these two. These results are discussed in terms of the possible relationship between disordered eating tendencies and weight loss pressures, as well as practical implications and future research.
Recovering Stephen Leacock: "Sunshine Sketches of a Little Town" and the cultural production of value.
Creators: name: Meakin, Jonathan M.
Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: Literature, Canadian (English).

description: The central aim of Recovering Stephen Leacock: Sunshine Sketches of a Little Town and the Cultural Production of Value is simultaneously to rupture Leacock's canonized cultural signature and to recover the complexity of his cultural work. To this end, the present study maps Leacock's complexity as an antimodernist discourse of "accommodation and protest" in response to the cultural tensions of the late nineteenth- and twentieth-centuries. Moreover, through the conceptual model of Pierre Bourdieu's field of cultural production, this study explores how Leacock's antimodernist complexity is encoded in the production of his antimodernist discourse, career, texts--his cultural work--and the cultural authority and value invested in that work. The Introduction provides a critical survey of Leacock's production and reception, and outlines the relevance of T. J. Jackson Lears' notion of antimodernism, and Pierre Bourdieu's field of cultural production, to Leacock studies. Chapter One, "Discourse: Visionary and Reactionary--Leacock as an Antimodernist" discusses Leacock's work as an interdisciplinary antimodernist discourse of cultural authority and value. Chapter Two, "Career: The Perfect Salesman and A Cultural Authority," explores Leacock's careers as a professional writer and academic in terms of his antimodernist negotiation of authority and value. Chapter Three, "Text: Antimodernist Sketches of a Little Town," provides a test-case reading of Sunshine Sketches of a Little Town as an antimodernist text that reflects a number of Leacock's concerns towards the realization of social justice. Finally, the Conclusion intimates how this present study as a whole underscores the need, and highlights the possibility, of reading Leacock in terms of broader, international literary-historical periods.

description: Computer simulations have been used to study the effect of narrow switched-beam transmission and power control at the base station on the interference characteristics and traffic capacity of digital cellular (IS-136) systems. In simulations, four narrow beams in place of a sectored antenna pattern are used, and a power control mode with up to 30 watts maximum transmitted power is applied. Results indicate that with transmission on four narrow beams at the base station, the improvement in carrier to interference ratio (C/I) is more than 4 dB. Furthermore, with narrow beam transmission and the base station power control, the total improvement in C/I is 8 to 10 dB. If this C/I gain is utilized to maximize the amount of served traffic, the system capacity can be enhanced by more than 100%. Therefore, improvements in system performance with increased capacity and improved quality are expected by incorporating narrow beam transmission and base station power control.

description: Forests provide bird communities with various resources, including food and habitats. Thus, forest attributes, such as size, structure, and species composition, influence the distribution and dynamics of bird species. This study was conducted to examine the association between forest condition, bird species abundance, and diversity within Chungcheongnam Province, South Korea. Zero-inflated binomial regression models were used to analyze a total of 1646 sampling points of abundance and diversity. Forest area, distance to forest edge, and tree size class were selected as covariates. Negative associations between forest area and overall bird abundance and species richness were indicated, whereas distance to forest edge was not a significant factor. This insignificance may be attributed to the relatively small, fragmented, and homogenous forest areas across the studied region. Results for individual bird species indicated that six out of the 35 major bird species had significant associations to the forest edge and three species showed a preference for the interior of the forest. The results of this study imply that other factors, such as food availability and biotic interaction, are more important when determining habitat preference in a relatively homogenous area with a long history of human disturbance.

description: Background: Depression and anxiety are leading causes of disability worldwide but often remain undetected and untreated. Smartphone and wearable devices may offer a unique source of data to detect moment by moment changes in risk factors associated with mental disorders that overcome many of the limitations of traditional screening methods. Objective: The current study aimed to explore the extent to which data from smartphone and wearable devices could predict symptoms of depression and anxiety. Methods: A total of N = 60 adults (ages 24–68) who owned an Apple iPhone and Oura Ring were recruited online over a 2-week period. At the beginning of the study, participants installed the Delphi data acquisition app on their smartphone. The app continuously monitored participants' location (using GPS) and smartphone usage behavior (total usage time and frequency of use). The Oura Ring provided measures related to activity (step count and metabolic equivalent for task), sleep (total sleep time, sleep onset latency, wake after sleep onset and time in bed) and heart rate variability (HRV). In addition, participants were prompted to report their daily mood (valence and arousal). Participants completed self-reported assessments of depression, anxiety and stress (DASS-21) at baseline, midpoint and the end of the study. Results: Multilevel models demonstrated a significant negative association between the variability of locations visited and symptoms of depression (beta = −0.21, p = 0.037) and significant positive associations between total sleep time and depression (beta = 0.24, p = 0.023), time in bed and depression (beta = 0.26, p = 0.020), wake after sleep onset and anxiety (beta = 0.23, p = 0.035) and HRV and anxiety (beta = 0.26, p = 0.035). A combined model of smartphone and wearable features and self-reported mood provided the strongest prediction of depression. Conclusion: The current findings demonstrate that wearable devices may provide valuable sources of data in predicting symptoms of depression and anxiety, most notably data related to common measures of sleep.

description: The colloidal stability of nanoparticles NP in soil solution is important to assess their potential effects on ecosystems. The aim of this work was to elucidate the interactions between initial particle size di, particle number concentration (N0) as well as the characteristics of dissolved organic matter (DOM) for stabilizing Ag NP and TiO2 NP. In batch experiments using time-resolved dynamic light scattering (DLS), we investigated the aggregation of TiO2 NP (79 nm, 164 nm) and citrate-stabilised Ag NP (73 nm, 180 nm) in Ca2+ solution (2 mM) and two soil solutions, one extracted from a farmland and one from a floodplain soil (each containing 2 mM Ca2+). Our results demonstrate that the initial particle size and the particle number concentration affected aggregation more strongly in the presence of DOM than without DOM. The composition of DOM also affected aggregate size: NP formed larger aggregates in the presence of hydrophilic DOM than in the presence of hydrophobic DOM. Hydrophilic DOM showed a larger charge density than hydrophobic DOM. If Ca2+ is present, it may bridge DOM molecules, which may lead to greater NP destabilization. The results demonstrate that DOM interaction with NP may not only vary for different DOM characteristics (i.e. charge density) but may also be influenced by the presence of multivalent cations and different NP material; thus the effect of DOM on NP colloidal stability is not uniform. © 2019 The Authors.

Negative differentiated optical injection of semiconductor lasers

Subjects: subject: Engineering, Electronics and Electrical.

description: In this thesis, we present a new technique of semiconductor modulation that maintains simplicity of design and overcomes many deficiencies of current direct modulation technologies. This technique of negative differentiated optical injection locking, makes it possible to equal or improve the Q factor and reduce the chirp penalty of a directly modulated laser source. Using this new structure we stabilize the dielectric properties of the slave laser, beyond the performance of standard optical injection locking, by reducing the refractive index excursion in the active layer and minimizing optical frequency chirp. This enables more reliable bandwidth efficient communication without compromising linearity or demanding prohibitive control complexity. We contrast this technique with direct, standard injection locking, electro absorption and Mach-Zehnder modulators at various speeds and find that our particular technique demonstrates desirable trade-offs between performance, control flexibility and simplicity.

description: Classifying the sounds of species is a fundamental challenge in the study of animal vocalizations. Most of these studies are based on manual inspection and labeling of sound spectra, which relies on agreement between human experts. In this study recorded songs of crickets (Grylloidea) from Thailand and Ecuador are analysed and classified automatically. For this, the locations of pulses are determined and different features from the time and frequency domain are extracted automatically from the time series. For the categorization of the sound patterns these different features are combined through data fusion, temporal fusion and decision fusion. Local features and global features of the sound patterns are distinguished. For the classification a fuzzy-k-nearest-neighbour classifier is used. This classifier scheme exhibits a large similarity to artificial neural networks, in particular to radial basis function neural networks. We present classification results for a data set of 28 different species.

description: This classification of speech vs. noise or speech vs. music can be used in speech/audio signal processing applications as an important part to achieve a lower bit-rate or to enhance the performance of coding in multimedia communications. In recent years, some research on the classification has been published. In the previous work some traditional classification algorithms were used, such as linear Least Mean Squares, the Nearest Neighbour and the Quadratic Gaussian algorithms. Some of the previous work also used machine learning software and neural networks with basic training algorithms. This thesis provides an extensive experimental simulation of the speech classification problem. In this thesis, the Extended Kalman Filter algorithm is proposed to train a neural network classifier. Our experiments show that using neural networks in speech/noise/music classification produces a more robust and powerful classification than other traditional algorithms. Furthermore, the Extended Kalman Filter provides a fast convergence and gives results near the global optimal. Our results show that the learning algorithm chosen to train the neural network is very important to the final results. Therefore, the neural network classifier trained with the Extended Kalman Filter is compared with the traditional classification methods but also with other neural classifiers trained with different learning algorithms. The experiments performed for the thesis are clean speech vs. noise classification, clean speech vs. music classification and active/inactive speech classification of noisy speech.

description: We report our first discoveries of high-redshift supernovae from the Subaru HIgh-Z sUpernova CAmpaign, the transient survey using Subaru/Hyper Suprime-Cam (HSC). We report the discovery of three supernovae at the spectroscopically confirmed redshifts of 2.399 (HSC16adga), 1.965 (HSC17auzg), and 1.851 (HSC17dbpf), and two supernova candidates with the host galaxy photometric redshifts of 3.2 (HSC16apuo) and 4.2 (HSC17dsid), respectively. In this paper, we present their photometric properties, and the spectroscopic properties of the confirmed high-redshift supernovae are presented in the accompanying paper. The supernovae with the confirmed redshifts of z similar or equal to 2 have the rest-ultraviolet peak magnitudes close to -21 mag, and they are likely superluminous supernovae. The discovery of three supernovae at z similar or equal to 2 roughly corresponds to the approximate event rate of similar to 900 +/- 520 Gpc(-3) yr(-1) with Poisson error, which is consistent with the total superluminous supernova rate estimated by extrapolating the local rate based on the cosmic star formation history. Adding unconfirmed superluminous supernova candidates would increase the event rate. Our superluminous supernova candidates at the redshifts of around 3 and 4 indicate the approximate superluminous supernova rates of similar to 400 +/- 400 Gpc(-3) yr(-1) (z similar or equal to 3) and similar to 500 +/- 500 Gpc(-3 )yr(-1) (z similar to 4) with Poisson errors. Our initial results demonstrate the outstanding capability of HSC to discover high-redshift supernovae.

description: This paper aims at analysing McEwan’s novel Atonement from the point of view of the legal issues embedded in the novel. It will focus in particular on an issue which at a first reading appears as a side-element in the text and remains on the background, but which nonetheless, constitutes a main element of the plot, and the one upon which the whole question of atonement actually relies: the trials, real ones and symbolic ones.

description: Dilaga un discorso monofonico, nel quale la voce di quella che costituisce oramai una parte considerevole della popolazione attiva è del tutto assente; se ne registrano piuttosto i movimenti, come se fossero fenomeni naturali minacciosi (le ondate, i flussi) o ancora più minacciose orde (l’invasione). Costante è la rappresentazione sotto forma di deviazione cognitiva e devianza sociale. La prospettiva, quella di un Noi che definisce il Loro come problema, e così facendo si autoistituisce; si lasciano parlare da un linguaggio preformato, grottesco, senza prospettive di redenzione, persone che si suppongono colte, convinte di esprimere pensieri e capacità di scelta. Come meravigliarsi del razzismo più balordo, se lo si nutre quotidianamente di una lingua capace di influire in maniera catastrofica sulla percezione e sull’azione? Nulla di più volgare di questa chiamata a complice, la strizzata d’occhio: loro sono così, noi invece… Noi chi?

Psychological characteristics of individuals who engage in online sexual activity (OSA)

description: Engaging in online sexual activity (OSA) is a growing phenomenon in much of the Western world. It is frequently argued that excessive involvement in such activity can result in a number of negative consequences including increased psychopathology and psychosocial difficulties, however to date there is little empirical research supporting this claim (Daneback, Cooper, & Mansson, 2005). The overall aim of this thesis was to investigate the expression of sexuality on the Internet using an online questionnaire that surveyed the psychological characteristics and online behaviours of individuals who engage in online sexual activity (OSA). The anonymous questionnaire was posted on sexually oriented newsgroups yielding a sample of 1325 men and women. Participants were aged 18 to 80 years of age, (M = 42 years), and approximately 60% of participants identified as non-heterosexual. Ninety-two percent were male and most engaged in OSA for at least 12 hours per week. Participants in the current study were older, more likely to be male, identify as non-heterosexual (gay, lesbian, bisexual), and be heavier users of OSA than participants from earlier online studies (e.g., Cooper, Morahan- Martin, Mathy, & Meheu, 2002; Cooper, Sheerer, Bois, & Gordon, 1999). Results from the Internet Sex Screening Test (ISST, Delmonico, 1997) indicated that most participants were classified within the At-Risk or High-Risk groups, suggesting that their OSA was likely to be interfering with important aspects of their lives. Participants’ sex and their sexual orientation were related to their pattern of OSA and their offline meeting behaviour. Participants’ Risk-level on the ISST and their sexual orientation were related to scores on depression, anxiety, stress, loneliness and impulsivity, however this pattern was not the same for males and females. Adult attachment style was also related to participants’ OSA. Securely attached participants were more likely to be classified within the Low-Risk group on the ISST and spend less time engaged in OSA. Overall, spending more time engaged in OSA and scoring higher on the ISST was associated with higher levels of depression, anxiety, stress, impulsivity, social loneliness and emotional loneliness. Findings were discussed in terms of methodological implications, suggestions for future research and also implications for clinical psychologists.

description: Abstract Nested case‐control designs are attractive in studies with a time‐to‐event endpoint if the outcome is rare or if interest lies in evaluating expensive covariates. The appeal is that these designs restrict to small subsets of all patients at risk just prior to the observed event times. Only these small subsets need to be evaluated. Typically, the controls are selected at random and methods for time‐simultaneous inference have been proposed in the literature. However, the martingale structure behind nested case‐control designs allows for more powerful and flexible non‐standard sampling designs. We exploit that structure to find simultaneous confidence bands based on wild bootstrap resampling procedures within this general class of designs. We show in a simulation study that the intended coverage probability is obtained for confidence bands for cumulative baseline hazard functions. We apply our methods to observational data about hospital‐acquired infections.

description: Die additive Fertigung, insbesondere das Laser-Beam-Melting (LBM), bietet großes Potenzial für eine wirtschaftlich flexible Produktion hochkomplexer Bauteile. Gleichzeitig stellt ihre Integration Unternehmen vor erhebliche Herausforderungen: Hohe Investitionen in Maschinen und Personal führen häufig dazu, dass Fertigungsaufträge an spezialisierte Dienstleister ausgelagert werden. Diese Dienstleister stehen nun vor der Herausforderung, trotz einer Vielzahl unterschiedlicher Fertigungsaufträge eine effiziente Auftragsabwicklung zu gestalten. Durch die komplexen Zusammenhänge in der Auftragsabwicklung liegt die durchschnittliche Maschinenauslastung derzeit jedoch bei unter 60 Prozent. Die Folge sind hohe Bauteilkosten, welche wiederum die breite industrielle Anwendung hemmen.

Um die Auftragsabwicklung von LBM-Dienstleistern effizienter zu gestalten, wurde das Forschungsprojekt „Intelligente Produktionsplanung und -steuerung für das Laser-Beam-Melting“ (IPPSLaBeM) gestartet. Im Rahmen dessen wurde ein angepasster Auftragsabwicklungsprozess auf Basis des Aachener PPS-Modells entwickelt. Er zielt darauf ab, die Auftragsabwicklung entlang etablierter Best Practices systematisch zu strukturieren und dadurch Effizienz, Transparenz und Wirtschaftlichkeit zu steigern. Eine Orientierung am Referenzprozess ermöglicht nicht nur eine Senkung der Kosten durch verbesserte Prozessqualität, sondern eröffnet auch neue Chancen für die Digitalisierung und Prozessautomatisierung.

Zur Integration der theoretischen Ansätze in den betrieblichen Ablauf wurde der vorliegende Leitfaden entwickelt. Er befähigt LBM-Dienstleister, ihre bestehenden Auftragsabwicklungsprozesse gezielt anhand des Referenzmodells anzupassen. Durch praxisnahe Handlungsempfehlungen unterstützt der Leitfaden KMU dabei, ihre ge-wachsenen Strukturen zu hinterfragen, zu transformieren und eine Grundlage für die digitale Transformation zu schaffen.

Das Vorgehensmodell ist in drei Phasen unterteilt, die Unternehmen Schritt für Schritt bei der Anpassung ihrer Auftragsabwicklung an das Referenzprozessmodell unterstützen. Dabei beginnt das Vorgehensmodell mit der systematischen Überprüfung der Voraussetzungen und Rahmenbedingungen für die Anwendung des Vorgehensmodells. Sind diese sichergestellt, folgt eine Phase mehrschrittiger Handlungsanweisungen, die KMU befähigen, einen Teilbereich der eigenen Auftragsabwicklung zu modellieren sowie zu analysieren, Strategien zur Prozessangleichung aufzustellen und letztlich die Veränderungen im Unternehmen zu verankern. Die finale Phase dient der Reflexion der Vorgehensweise und der Entscheidung über das weitere Verfahren. Dadurch entsteht ein iteratives Vorgehen, welches zur kompletten Angleichung der Auftragsabwicklung führt.
