Previous research works on solid oxide fuel cells (SOFCs) have mainly focused on the large length scale phenomena, such as physical and chemical transport phenomena at macroscale. A new approach is proposed in this work, which combines concepts from all-atom (AA) modeling with coarsegraining (CG) molecular dynamics (MD) method to reveal the replacement mechanism of Yttria-Stabilized Zirconia (YSZ)

During the last ten years or so, much effort has been spent on developing software architecture by analogy with hardware architecture from where the idea seems to originate. Much of the work has been devoted to specifying standard program units, called components, and their connections. The architecture is then the specific organization of these components and connections. In this paper, I suggest

The effect of airborne particulate matter on human health is today of considerable research interest. Essential parameters include elemental composition sampling with low pressure cascade impactors and analysis by particle induced x-ray emission spectroscopy (PIXE). It is shown that the aerosol generated by arc welding operations is several orders of magnitude denser than aerosols in ambient air.

Increasing aridity is one major consequence of ongoing global climate change and is expected to cause widespread changes in key ecosystem attributes, functions, and dynamics. This is especially the case in naturally vulnerable ecosystems, such as drylands. While we have an overall understanding of past aridity trends, the linkage between temporal dynamics in aridity and dryland ecosystem responses

The ABBI (Audio Bracelet for Blind Interaction) device is designed for visually impaired and blind children to wear on the wrist and produce sound based on the movement of the arm through space. The primary func- tion is to inform a child (or adult) about his/her own movements to aid spatial cognition rehabilitation. How- ever, the device could also be worn by friends and family and be used to inf

The business model concept is becoming increasingly popular within e-businesses and e-business research. However, the concept is often used relatively independently from theory, meaning model components and their interrelations are relatively obscure. This paper analysis three e-business models taxonomies based on a generic business model, which include customers and competitors, the offering, act

We test the hypothesis that the spread in the age-metallicity plot of the solar neighborhood is due to a mixture of stars belonging to kinematically different sub-populations of the Galactic disk, i.e., the thin and the thick disk. We use a kinematic subsample of similar to 600 stars from a sample of similar to 6000 dwarf and subgiant stars from the Hipparcos catalog. All of these stars have a ful

Lattice Boltzmann method (LBM) is a method that can be used to capture the detailed activities of the transport processes at microscale. Here LBM is used to model the porous anode for an anode-supported Solid Oxide Fuel Cell (SOFC). The purpose of this study is to investigate the effects of electrochemical reactions on the transport processes by a 3D model at microscale. A porous 3D modeling domai

The aim of this masters’ thesis is to examine how libraries can better services for patrons with invisible disabilities. My hypothesis is that although libraries are legally obliged to pay special attention to persons with disabilities, in reality the special needs of persons with invisible disabilities are often ignored. Invisible disabilities are disabilities that are not immediately apparent. T

In order to achieve the environmental quality goals it is required to reduce emissions, particularly carbon dioxide emissions from road transport. A step in the right direction, from an environmental perspective, is to increase the use of electric railway. This means that a well-developed and functioning network that is customized to the European standards is required in order to motivate and mana

Vårdnadsrelaterade tvister har ökat markant de senaste åren. För varje tvist finns det minst ett barn som påverkas, men barn saknar i svensk rätt både talerätt och processbehörighet i dessa mål. Det finns emellertid vissa rättigheter som ska tillförsäkra att barnets intressen tillgodoses i processen; barnets bästa och barnets rätt att komma till tals. Barn har rätt att uttrycka sina åsikter och atFamily law disputes concerning child custody, residence of the child and the child’s right of access with a parent have increased significantly over the last years. This means that more children get involved in these kinds of disputes every year. In Sweden, children have no right to litigate and no procedural capacity in these proceedings. Instead there are other rights that are supposed to ensure

Voice problems are common among workers in occupations with high demands on oral communication. For sustaining vocal health, it is important to find efficient ways for how to reduce strain on the voice at work, and one way to do so is optimizing the room acoustics for communication. However, to date we do not know enough about what kind of room acoustic conditions that support voice and speech mos

The purpose of this paper is to discuss how theories of social and intellectual development of scientific fields can be used to analyze LIS, and especially its relationship to other research areas and the library and information field of practice. Scientific fields can be seen as reputational work organizations, where degrees of task uncertainty and mutual dependency control the coordination and d

Wear in forming tools and contact problems between sheet-metal and tool-material are common problems in manufacturing industries and sheet-metal-parts production. In this paper recent tool material experiences are presented. Quantitative determination of wear has been performed using micro hardness indentions made on the tool surface prior to pressings and thereafter measured. Wear tests are perfo

When a Virtual Environment (VE) is designed, decisions regarding the navigation of the viewpoint, interaction with objects, and the behavior of the VE itself are made. Each of these can affect the usability and the cognitive load on the user. A VE that had previously been constructed as a prototype tool for the assessment of brain injury has been studied to establish the consequences of such desig

Mass spectrometry was used to determine the endotoxin (lipopolysaccharide, LPS) marker 3-hydroxytetradecanoic acid and 3-deoxy -D-manno-2-octulosonic acid in cigarette tobacco and smoke particles. Tobacco from cigarettes of different brands purchased in four different countries in Europe and Asia contained similar amounts of LPS. Indoor exposure to environmental tobacco smoke (ETS) in rooms of smo
