Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The NTT at La Silla, Chile and NOT on La Palma were used for VRI photometry of 9 Edgeworth-Kuiper objects and 3 Centaurs. For the NOT observations growth-curve fitting was applied in the photometric reductions. The spread in colour of the observed Centaurs and Edgeworth-Kuiper objects is large.

Aesthetic Flexibility : Modularity of Visual Form in Product Portfolios and Branded Products
- 2016
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The increase in competition amongst companies that produce complex or large product portfolios has created a need to utilise modularity strategies not only to flexibly manage technical complexity in a costeffective manner but also for visual appearance. This research aims to understand how the visual appearance of products is affected by modular product development strategies. Specifically, the aim is to understand how such strategies induce constraints and generate possibilities for management of visual appearance in the design process.Five studies have been conducted during the course of this licentiate thesis. Two were conducted with professionals and students in design, while the remaining three are theoretical studies based on findings in the literature, theory building, and experimental research. The goal has been to investigate how designers work when they are put to the task of changing and developing the designs of complex products that are part of a portfolio. The challenge has been to study what suitable strategies exist that manage complex products and product brands, then investigate how these influence designers’ practices.The first study examined how coherence towards a product category influences the design of new products. The outcome of the study was a method to explore visual coherence and diversity in the appearance of a product category.The remaining four studies investigated how modularity, brand management and the redesign of product portfolios influence a design process. The second study described a design phenomenon known as aesthetic flexibility, which was further explored in studies three and five. The outcome from these studies was a proposal for four aesthetic flexibility strategies.The fourth study investigated in what way portfolio extension strategies found in brand management and design research are related, and how such strategies influence aesthetic flexibility. The results from study four were illustrated as a model.The main contribution of this work is the phenomenon of ‘aesthetic flexibility’, which helps understand the factors that influence designers when working with branded modular products. Understanding visual flexibility serves as a starting point in further investigations of how different development strategies affect the possibilities for visual product design.The findings of this work serve to illustrate and explain a complex and multi-facetted design phenomenon which many designers manage more or less intuitively today, thus advancing academics’, teachers’ and professional designers’ understanding of the field.

Desirability in the development of In-Car Infotainment Systems

Ingår i: Workshop: User Experience in Cars.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper describes a workflow for designing experiences whileinteracting with an advanced driver assistant system. Future driver assistancesystems that utilize sensors and Car2X-communication in order to detect threatsin the car environment can help the driver to avoid collisions. To increase theacceptance of such a system, the interaction between the driver and the systemshould be able to generate positive experiences. To generate those experiences,a story-based design workflow was used. Concepts created with this workflowshould be able to address specific psychological needs of the driver. Theimplementation of this workflow revealed different schemes of positiveexperiences during driver interaction in critical situations.

Mercury: First Spectra from 0.7 to 5.5 mum Support Low FeO and Feldspathic Composition

- Spectral measurements of Mercury's surface show an absence of absorptions centered near 0.9 and 1.2 micrometers. At the Moon these absorption bands are ubiquitous at varying depths. We have obtained spectra from the Moon for comparison. The lunar results are shown in a companion abstract.

UBVRI Photometry of Mecury's Integral Phase Curve
- 2007
-
Konferensbidrag (populärvet., debatt m.m.)abstract
- We present results from a photometric survey of Mecury's survey of Mecury's integral phase curve in the Johnson UBVRI system, obtained with the 0.9-m Westerlund Telescope in Uppsala, Sweden. CCD observations of the integrated disk have been obtained for the phase angle range 22-152 degrees. This is the first integral phase curve survey covering the extended visible spectrum of Mecury. We have derived absolute magnitudes and color indices from which Bond albedo, geometric albedo and phase integral have been determined for all bands.We have fitted the data in each band with the Mallama et a. (2002) V-band phase curve which is based on a wider range of more densely sampled phase angles. A magnitude-scaled Mallama phase curve provided adequate fits for each band within the photometric error budget. This implies no evidence of phase reddening in any color, which is in contrast to the Moon. The phase reddening for the Moon was determined by Lane and Irvine (1973) to 0.001 mag/degree between the wavelengths 445 nm and 550 nm.These data will be modeled to derive light scattering properties of the regolith. Of particular interest is the prediction of a disk-averaged normal albedo at 1064 nm with implications for the returned signal strength of the BepiColombo laser altimeter BELA (Gunderson et al, 2006).

Tidskriftsartikel (refereegranskat)abstract
- The Spherical Mobile Investigator for Planetary Surface (SMIPS) concept aims at making use of the latest developments within extreme miniaturization of space systems. The introduction of Microelectromechanical Systems (MEMSs) and higher level Multifunctional Microsystems (MMSs) design solutions gives the robot high performance per weight unit. The untraditional spherical shape makes it easily maneuverable and thus provides a platform for scientific investigations of interplanetary bodies. Preliminary investigations of the SMIPS concept show several advantages over conventional robots and rovers in maneuverability, coverage, size, and mass. A locomotion proof-of-concept has been Studied together with a new distributed on-board data system configuration. This paper discusses theoretical robot analysis, an overall concept, possible science, enabling technologies, and how to perform scientific investigations. A preliminary design of an inflatable multifunctional shell is proposed.
