Flerspråkighetens potential i dramatiska verk
- 2022
-
Konstnärligt arbete (övrigt vetenskapligt/konstnärligt)abstract
- "The potential of multilingualism in dramatic works" is an artistic research project that aims to investigate, develop, and deepen the practice of writing multilingual drama for an imagined audience in Sweden. Through placing significant focus on the playwright's practice, the goal is to contribute to the artistic development of dramatic writing in Sweden and in other Swedish-speaking contexts.By using sociolinguistic theories and terms around multilingualism, both the artistic practice and the discourse surrounding it are developed and challenged. Through the application of an integrated ideology of multilingualism, language ideologies based on a monolingual norm are contradicted. In this way, the project makes room for silenced and marginalized voices and perspectives that rarely take or receive a place in Swedish performing arts contexts.Considering language, and thus multilingualism, as social practice and action is the starting point for the research. This post-structuralist approach is in line with the theories of sociologist Pierre Bourdieu and language theorist Michael Bakhtin. In this research drama is considered as both practice and as action. Central concepts are linguistic repertoires, translingualism and speech acts.Within the project, two dramatic works have been created, ASIA/ÄRENDE and UniZona & PolyZona. These constitute the artistic result of the research and can both be described as dialogical polyvocal plays. Common and central to both works is that multilingualism permeates them and constitutes their formal core. The multilingualism has consequences that affect the dramaturgical and musical structures.The creation of the works has taken place in dialogue and collaboration with multilingual actors, directors and translators in Sweden and Finland. The form of the artistic work has been conversations, workshops and periods of writing, translation, and design. Through these processes and works, the issues have been successively investigated. As tools for analysis, reflection and discussion, four categories have been created: dramaturgical, political, emotional and communicative potential. With the help of these, the concrete functions of multilingualism in both dramatic works are examined with the aim of making visible the potential of multilingualism in dramatic works.The project demonstrates that multilingual dramatic writing requires different, less traditional approaches and in this way contributes to an expanded practice for the playwright. The methods used in the creation of the works have been collaborative, transcultural and dialogic, shifting between practices and acts of listening and composing."The potential of multilingualism in dramatic works" aims to show the enormous artistic, creative, political, emotional and communicative potential that multilingualism can bring to the dramatic work and, by extension, the performing arts.

Multiscale Constitutive Modeling of Heterogeneous Engineering Materials
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This work deals with different methods used to determine heterogeneous constitutive model parameters for macro-scale finite element models, based on microstructural variations, caused by the manufacturing process. These methods could be applied to decrease modeling errors associated with the material behavior, improving the predictive capabilities of structural analyses in simulation-driven industrial product development. By providing engineers with more sophisticated tools and methods which lets them consider the complex relationships between the manufacturing process, the resulting microstructure and the final properties, manufactured components have the potential to be further optimized with respect to both weight and performance, reducing their cost and environmental impact.An empirical approach for cast components is presented in Papers I & II, where material testing is used as a basis for constitutive model parameter extraction via optimization. Linear models were created for both thermo-mechanical and thermo-physical material properties, by characterizing specimens extracted from different regions in a lamellar graphite cast iron cylinder head. These models were used to generate heterogeneous constitutive model parameters for the cylinder head, based on the solidification time as predicted by casting process simulations. The influence of several commonly made casting-specific engineering simplifications were investigated, and it was shown that non-trivial errors of a potentially large magnitude are introduced by not considering e.g. the compressive behavior of the material, residual stresses from the casting process, the temperature dependency of the material, or the process-induced heterogeneity.Paper III describes a statistical homogenization-based method, for modeling of anisotropic fiber reinforced materials. A non-linear anisotropic constitutive model was developed and implemented in commercial finite element codes, which is able to consider heterogeneous fiber orientations using only one material definition. The anisotropic elastic constitutive tensor is determined from fiber-matrix homogenization, and orientation averaging using second- and fourth order fiber orientation tensors provided by injection molding simulations. The plastic constitutive parameters are determined by optimization against experimental tensile tests using specimens with different fiber orientations. The method was demonstrated using a injection molded 50 wt.% short glass fiber reinforced plastic.A pixel/voxel-based method is presented in Papers IV (2D) & V (3D), for simple and efficient generation of reduced numerical microstructure models using imaging data as input. The input micrograph or image stack is split into subdomains, which are evaluated individually using numerical or semi-analytical homogenization. The constitutive tensor of each subdomain is mapped to a new, reduced numerical model. The purpose of this approach was to support component level analyses, by representing process-induced microstructural imperfections like e.g. porosity on the macro-scale, in a computationally efficient way. The geometrical description of the microstructure can be retrieved from experimental imaging methods like Scanning Electron Microscopy (SEM) or X-ray based Computed Tomography (CT). Alternatively, it can be approximated from phase field or manufacturing process simulations. The method was demonstrated by reducing a 2D aluminium micrograph by 99.89%, with material property errors of less than 0.5% in Paper IV. Also, in paper V by reducing a complex high-resolution 3D aluminum shrinkage porosity by 99.2%, with a material property error of approximately 1%. The method significantly reduces the complexity of building finite element models of complex microstructures, where the pre-processing step is replaced by image segmentation.

Process-Induced Local Material Variations in Finite Element Simulations of Cast and Fibre Reinforced Injection Moulded Components
- 2019
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this thesis is to provide an overview of the methods used in the appended papers, in order to consider heterogeneous material properties in finite element simulations by using process simulations as input. The work deals with both injection moulded and cast components, and focuses on process-induced local material variations and their effect on component performance.The influence of heterogeneous properties originating from the casting process as well as some other common simplifications, which are made in finite element analyses, are evaluated for a cast iron component. It is found that commonly neglected properties such as compressive strength, residual stresses, temperature dependency and heterogeneous properties have a non-trivial and potentially large influence on the simulation results.Lastly, a computational method for fibre reinforced plastics is presented. The methodology enables designers to consider the non-linear anisotropic properties of fibre-reinforced polymers, due to the flow-induced fibre orientation predicted by injection moulding simulations. The method allows material data assignment in each integration-point of the structural mesh. The method is demonstrated to capture the behaviour of the full range of fibre orientations simultaneously with good accuracy.

Composing The Performance : An Exploration Of Musical Composition As A Dramaturgical Strategy In Contemporary Intermedial Theatre
- 2018
-
Konstnärligt arbete (övrigt vetenskapligt/konstnärligt)abstract
- This thesis explores musical composition in the context of contemporary theatre. It suggests methods where compositional thinking – broadly understood – can be used as a dramaturgical device in the creation of theatre performances. Such musicalization of theatre provides new methods for an artistic practice and questions traditional artistic hierarchies and working structures. The investigation departs from a process of transference of radiophonic art to stage performances. From this a series of interdisciplinary works in the intersection between concert, theatre performance, radio play and music theatre has been created, each with different approaches to the roles and functions of musical composition. Through these works the creative processes and methods are examined and analysed. The notion of vertical dramaturgy and polyphony in theatre contexts is discussed and demonstrated, which pinpoints the significance of interaction between the elements of a performance. The interplay between dramatic writing, acting methods and musical composition is under scrutiny, as is the way in which visual elements as video, light and scenography are integrated into polyphonic theatre experiences. Transformation is an essential compositional and dramaturgical tool as it allows a performance to move seamlessly between different art forms, continuously creating new relationships. Through the research a model for interdisciplinary, collaborative work in performing arts emerges. The concepts of Shared space and Shared time are introduced and enable a collective ‘thinking-through-practice’ and expansion of the artistic roles. This joint arena of space and time opens up new connections, interactions and mutual exchanges between artists and art forms. The outcome provides a range of artistic methods in the field of contemporary intermedial theatre where musical composition is one of the dramaturgical devices for composing the performances.

Violence through the life cycle : A public health problem
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Violence has probably always been part of the human experience. Its impact can be seen, in various forms, in all parts of the world. In 1996, WHO:s Forty-Ninth World Health Assembly adopted a resolution , declaring violence a major and growing public health problem around the world. Public health work centers around health promotion and disease prevention activities in the population and public health is an expression of the health status of the population taking into account both the level and the distribution of health. Exposure to violence can have many aspects, differing throughout the life course — deprivation of autonomy, financial exploitation, psychological and physical neglect or abuse — but all types share common characteristics: the use of destructive force to control others by depriving them of safety, freedom, health and, in too many instances, life; the epidemic proportions of the problem, particularly among vulnerable groups; a devastating impact on individuals, families, neighborhoods, communities, and society.Methods: Three different data sources were used in the four articles, three cross-sectional studies (“Life and Health in Norrland” and “Health on Equal Terms 2004 and 2006”) and one longitudinal (“Level-of-Living Survey”).Results: We present an important picture of the strong association between exposure to violence and ill health through the life cycle. A population-based study showed an increased risk of poorer physical and psychological health among boys and girls aged 0-18, as reported by their mothers exposed to violence. Further, a strong association between those exposed to violence and physical and mental ill health was demonstrated in young adults aged 18-25, also after adjusting for possible confounders, specifically for women. Even in an elder group aged 65-84, representative results showed an extensive negative health outcome panorama caused by fear of crime and exposure to abuse both in elderly men and women. Lastly, in trying to provide additional empirical support for the association between exposure to violence and ill health the prospective study demonstrated that violence exposure in adolescence and young adulthood presented a negative association to severe illness burden in adulthood for women but not men.Conclusion: Exposure to violence among both men and women is an important risk factor for ill health and should receive greater attention in public health work. A strong association between violence and various health outcomes was demonstrated in different time periods through the life cycle.
