    Firenze University Press
    Details
    Publication Date: 2024-03-23
    Description: In the current socio-cultural scenario, the implementation of the university reform aimed at boosting third-level education calls for meditation within the discipline of Architectural Technology (ICAR 12). This review must address the research topics and academic profiles of PhD courses in the Technological Area, also in terms of fostering actions consistent with European strategic lines for the promotion of a knowledge society. Research, innovation, creativity and design are the keywords of this scenario that PhD students and lecturers must bear in mind when considering three fields of study: environmental design and landscape, building production and construction and works and services strategic for the community. This book "Research among innovation, creativity and design" develops the topics addressed during the VII OSDOTTA workshop (the network of PhD courses in the field of Architectural Technology) held at the Mantua campus of Milan Polytechnic on 15th-16th-17th September 2011.

    Teachers' Beliefs and Strategies when Teaching Reading in Multilingual Settings (2022)
    Logos Verlag Berlin | Logos Verlag Berlin
    Details
    Publication Date: 2023-02-01
    Description: Globalization has not only changed our society, it has also had a profound effect on education. Many schools deal with student populations that due to migration have become increasingly multilingual. Politically, few would argue against the importance of multilingualism; rather, it is promoted to the fullest. However, in practical terms the challenges associated with teaching and educational policies have increased manifold as a result of the linguistic diversity among student bodies. Reading is certainly regarded as a key learning skill, however, the question arises as to how the students' life-world multilingualism is taken into consideration. Furthermore, being considered part of teachers' professional competence, teachers' mental processes and perceptions (beliefs) have been the focus in several different academic fields. Previous research suggests that there are significant links between teachers' beliefs and practices. This thesis explores the aforementioned aspects in greater detail, with the overall aim to gain a deeper understanding of teachers' beliefs and strategies when teaching reading in multilingual settings. Using a cross-disciplinary, qualitative research approach, the empirical inquiry is based on case studies within different, linguistically diverse settings. The case studies include classroom observations as well as teacher interviews in German, Swedish and Chilean grade 4 classrooms.

    Modeling of Moving Sound Sources Based on Array Measurements (2021)
    Logos Verlag Berlin | Logos Verlag Berlin
    Details
    Publication Date: 2024-04-14
    Description: When auralizing moving sound sources in Virtual Reality (VR) environments, the two main input parameters are the location and radiated signal of the source. An array measurement-based model is developed to characterize moving sound sources regarding the two parameters in this thesis. This model utilizes beamforming, i.e. delay and sum beamforming (DSB) and compressive beamforming (CB) to obtain the locations and signals of moving sound sources. A spiral and a pseudorandom microphone array are designed for DSB and CB, respectively, to yield good localization ability and meet the requirement of CB. The de-Dopplerization technique is incorporated in the time-domain DSB to address moving source problems. Time-domain transfer functions (TDTFs) are calculated in terms of the spatial locations within the steering window of the moving source. TDTFs then form the sensing matrix of CB, thus allowing CB to solve moving source problem. DSB and CB are further extended to localize moving sound sources, and the reconstructed signals from the beamforming outputs are investigated to obtain the source signals. Moreover, localization and signal reconstruction are evaluated through varying parameters in the beamforming procedures, i.e. steering position, steering window length and source speed for a moving periodic signal using DSB, and regularization parameter, signal to noise ratio (SNR), steering window length, source speed, array to source motion trajectory and mismatch for a moving engine signal using CB. The parameter studies show guidelines of parameter selection based on the given situations in this thesis for modeling moving source using beamforming. Both algorithms are able to reconstruct the moving signals in the given scenarios. Although CB outperforms DSB in terms of signal reconstruction under particular conditions, the localization abilities of the two algorithms are quite similar. The practicability of the model has been applied on pass-by measurements of a moving loudspeaker using the designed arrays, and the results can match the conclusions drawn above from simulations. Finally, a framework on how to apply the model for moving source auralization is proposed.

    Measurements in room acoustics (2023)
    Logos Verlag Berlin | Logos Verlag Berlin
    Details
    Publication Date: 2024-04-04
    Description: Regardless of the field, measurements are essential for validating theories and making well-founded decisions. A criterion for the validity and comparability of measured values is their uncertainty. Still, in room acoustical measurements, the application of established rules to interpret uncertainties in measurement is not yet widespread. This raises the question of the validity and interpretability of room acoustical measurements. This work discusses the uncertainties in measuring room acoustical single-number quantities that complies with the framework of the ``Guide to the Expression of Uncertainty in Measurement''(GUM). Starting point is a structured search of variables that potentially influence the measurement of room impulse responses. In a second step, this uncertainty is propagated through the algorithm that determines single-number quantities. A second emphasis is placed on the investigation of spatial fluctuations of the sound field in auditoria. The spatial variance of the sound field in combination with an uncertain measurement position marks a major contribution to the overall measurement uncertainty. To reach general conclusions, the relation between changes in the measurement location and the corresponding changes in measured room acoustical quantities is investigated empirically in extensive measurement series. This study shows how precisely a measurement position must be defined to ensure a given uncertainty of room acoustical single-number quantities. The presented methods form a foundation that can be exibly extended in future investigations to include additional influences on the measurement uncertainty.

    Media and Communication in Europe (2021)
    Logos Verlag Berlin | Logos Verlag Berlin
    Details
    Publication Date: 2023-02-02
    Description: This timely book explores how the media shape the Europeanization of the public sphere within the European Union (EU). Bringing together a range of international scholars in media studies and journalism and covering both traditional and online media, it argues that Europeanization is not just an idea - it is a real, ongoing process that we are experiencing every day. Assessing a wide range of actors and processes and acknowledging the diverse relationships between media and politics, the chapters edited by Agnieszka Stepinska reflect contemporary conceptualizations of Europeanization and unravel the complex mediatization of European politics. It covers topics as diverse as children's socialization within the European Union via kid's TV programmes; the impact of the 'Euroblogosphere' on policy decisions; and international broadcasting as one of the key elements to understanding new public diplomacy in Europe. Using the Polish EU presidency of 2011 as an extensive case study, the book's latter part shows what impact Poland's presidency had on its representation, both domestically and abroad, and questions the Presidency's actual power of attracting media attention. 'Media and Communication in Europe' is a valuable resource for any student and researcher interested in the complex relationship between the media and the EU.

    Study of an alternative phase field model for low interfacial energy in elastic solids (2022)
    Logos Verlag Berlin | Logos Verlag Berlin
    Details
    Publication Date: 2024-04-05
    Description: In 2005, the hybrid model was published by Prof. H.-D. Alber and Prof. P. Zhu as an alternative to the Allen-Cahn model for the description of phase field transformations. With low interfacial energy, it is more efficient, since the resolution of the diffuse interface is numerically broader for the same solution accuracy and allows coarser meshing. The solutions of both models are associated with energy minimisation and in this work the error terms introduced in the earlier publications are discussed and documented using one and two dimensional numerical simulations. In the last part of this book, phase field problems, initially not coupled with material equations, are combined with linear elasticity and, after simple introductory examples, a growing martensitic inclusion is simulated and compared with literature data. In addition to the confirmed numerical advantage, another phenomenon not previously described in the literature is found: with the hybrid model, in contrast to the examples calculated with the Allen-Cahn model, an inclusion driven mainly by curvature energy does not disappear completely. The opposite problem prevents inclusions from growing from very small initial configurations, but this fact can be remedied by a very finely chosen diffuse interface width and by analysing and adjusting the terms that generate the modelling errors. The last example shows that the hybrid model can be used with numerical advantages despite the above mentioned peculiarities.

    Anthropometric Individualization of Head-Related Transfer Functions Analysis and Modeling (2021)
    Logos Verlag Berlin | Logos Verlag Berlin
    Details
    Publication Date: 2024-04-14
    Description: Human sound localization helps to pay attention to spatially separated speakers using interaural level and time differences as well as angle-dependent monaural spectral cues. In a monophonic teleconference, for instance, it is much more difficult to distinguish between different speakers due to missing binaural cues. Spatial positioning of the speakers by means of binaural reproduction methods using head-related transfer functions (HRTFs) enhances speech comprehension. These HRTFs are influenced by the torso, head and ear geometry as they describe the propagation path of the sound from a source to the ear canal entrance. Through this geometry-dependency, the HRTF is directional and subject-dependent. To enable a sufficient reproduction, individual HRTFs should be used. However, it is tremendously difficult to measure these HRTFs. For this reason this thesis proposes approaches to adapt the HRTFs applying individual anthropometric dimensions of a user. Since localization at low frequencies is mainly influenced by the interaural time difference, two models to adapt this difference are developed and compared with existing models. Furthermore, two approaches to adapt the spectral cues at higher frequencies are studied, improved and compared. Although the localization performance with individualized HRTFs is slightly worse than with individual HRTFs, it is nevertheless still better than with non-individual HRTFs, taking into account the measurement effort.
