Everything is Translation (Including the Art of Making New Boots out of the Old Ones)

Presented here is a map that does not look like a map but as a sculpture, a glass tetrahedron sunk into a square slab of granite, three gold threads and a red ruby; nothing less than an attempt to capture what it means to be human. A creation epic of our own time, a pictured story of how the semiotic animal - a species blessed with the faculty of imagination - sacrifices an original difference by turning into a set of alternative identities. All told, the intricacies of power-and-knowledge captured by the interplay of the Peircean signs of symbol, icon and index, the paradigmatic lines of power (/, —, =) embracing each other in a perpetual ménage à trois. Everything cast onto the culturally prepared projection screens of religion (ideology), the arts and the sciences. Ethics and aesthetics two sides of the same coin, the tetrahedron the most beautiful of all geometric forms

USABILITY TESTING OF INTERACTIVE SYSTEMS CONDUCTED BY UNIVERSITY STUDENTS DURING A PANDEMIC

This case study describes a usability testing course in which students learn by practicing several evaluation methods. The on-campus format makes it possible for teachers and students to meet to discuss recorded test sessions and students can observe other students’ execution of pilot studies conducted on campus. The COVID-19 pandemic placed new demands on this course. In-person activities were avoided by some students and many test participants. Some student teams tried remote usability testing. Interestingly, screen recordings (with sound) of the test sessions show that remote testing sometimes helped the students focus more on observation and less on (inappropriately) guiding the test subjects. Another effect was that the students found it easier to recruit participants than during the previous years when the university was teeming with students, lecturers, and non-academic staff. However, the recruited participants were often notably limited to the students’ circles of friends

Solvation behavior of cellulose and xylan in the MIM/EMIMAc ionic liquid solvent system – parameters for small scale solvation

Ionic liquid treatment has been reported by several researchers as a possible step in the process of fractionating lignocellulosic biomass within the biorefinery concept. However, understanding how solvation can be achieved and how the feedstock biopolymers are affected is needed prior to a viable implementation. An effective two component solvent system for the wood components cellulose and xylan has been developed. Furthermore, the solvation of these components in the system consisting of the ionic liquid (IL) 1-ethyl-3-methylimidazolium acetate (EMIMAc) in a novel combination with the co-solvent 1-methylimidazole (MIM) is investigated. Focused beam reflectance measurement (FBRM) particle characterization in combination with microscopic analysis and molecular weight determinations (xylan) shows that cellulose and xylan can be most efficiently solvated using only 3 to 4% IL (n/n anhydro-glucose units and n/n anhydro-xylose units) and 9% IL, respectively, while still avoiding any significant polymer degradation. A model for a two-step process of cellulose solvation in the present system is proposed

Safety Margins and Feedback Strategies for AWD Vehicles

The vehicle industry today faces the two-fold challenge of reducing the environmental impact as well as increasing vehicle safety. Electrification of vehicles enables both of these challenges to be addressed by means of improved overall efficiency as well as providing increased possibilities to control the longitudinal forces of each wheel individually.The objectives of this study are to increase the fundamental understanding of the influence of longitudinal forces on vehicle handling and stability. Furthermore, the study shall support the industrial development of electrical driveline systems in particular.The results obtained in this work can be applied for analysis of the performance of current and upcoming driveline and brake systems and as components in the associated active control for these systems. Overall, the present work has expanded the fundamental framework of vehicle modeling, optimization formulations and graphical representations for analysis and optimization of a wide range of driveline system properties and vehicle level characteristics

Screening of hydrogen bonds in modified cellulose acetates with alkyl chain substitutions

This study aimed to elucidate how the glass transition temperature and water interactions in cellulose esters are affected by the structures of their side chains. Cellulose acetate, cellulose acetate propionate and cellulose acetate butyrate with three fractions of butyrates, all having the same total degree of substitution, were selected, and hot-melt pressed. The degree of substitution, structural properties, and water interactions were determined. The Hansen solubility parameters were calculated and showed that the dispersive energy dominates the total cohesive energy, followed by hydrogen bonding and polar energy. The glass transition temperature (Tg) decreased, counter-intuitively, with an increased total cohesive energy, which can be explained by the short-range hydrogen bonds being screened by the increased length of the substituents. The solubility and penetration of water in the cellulose esters decreased with increased side chain length, although the hydrogen bonding energies for all the esters were approximately constant
