Developing a Virtual Consumer: From Human Skin to FE Modelling

--- Att skapa en virtuell konsument: från mänsklig hud till FE modellering --- Interaktionen mellan konsument och produkt ur ett upplevelseperspektiv blir allt vanligare att simulera i den virtuella världen. För att nämna några exempel så simulerar IKEA liggkomfort medans bil- och flygplansindustrin simulerar sittkomfort. Det är ett spännande område av flera anledningar varav två är att dels så äIn the 'on-the-go' society of today, the use of single unit beverage packages has increased. Consequently, the interaction between the consumer and the package have also attracted greater interest when trying to gain advantages in a competitive market. One way of gaining such an advantage is by decreasing the developing costs of products: either by reducing time spent, or money invested in

Statistical Approach for the Design of Refresh-Free eDRAM with Retention Timing Constraint

In digital integrated circuits, memories are often a limiter for main performance, power and area. Over the past decade, integrated memories have gained dominance in terms of area and power cost. In applications like machine learning or image processing the area share can be above 80% consuming more than 50% of the total power budget. On-chip memories in CMOS technologies can be categorized as sta

Characterization of black corrosion in reinforced concrete structures: analyses of field samples from southern Sweden

I den här studien karakteriseras fenomenet anaerob korrosion utifrån både litteraturstudier om korrosionsprocesser och korrosionsprodukter samt genom undersökning av fältprover från betongkonstruktioner i salthaltiga undervattensmiljöer i södra Sverige. Anaerob korrosion av armering i vattenmättad betong är ett omfattande men hittills relativt ouppmärksammat problem. Detta fenomen kan leda till alIn this study, the phenomenon of black corrosion is characterized by both literature studies on corrosion processes and corrosion products, and by analyzing field samples from saline subaqueous concrete structures in southern Sweden. Anaerobic corrosion of reinforcement in water-saturated concrete is an extensive but yet relatively unnoticed problem. This phenomenon can lead to serious damages tha

Comparison of geospatial support in RDF stores: Evaluation for ICOS Carbon Portal metadata

The evolution of World Wide Web (WWW) into semantic web is happening with the aid of standards like Resource Description Framework (RDF), SPARQL and a few others from World Wide Web Consortium (W3C). Over the years, semantic data management technologies have been introduced as software platforms commonly known as RDF stores. Lately these RDF stores have been tested for processing and maintenance o

Investigating the accuracy of Digital Elevation Models from UAV images in areas with low contrast : a sandy beach as a case study

Elevation models are important in many applications in Geographical Information System (GIS), both when applying environmental analyses and in urban planning studies. The production of elevation models has been a difficult and expensive task using traditional surveying techniques. Remote sensing methods for producing digital elevation models have solved the difficult part of the task, which consis

Pedestrian Evacuation Modelled by a Conservation Law with a Two-inflection-point Flux Function

When designing a building one must consider safety aspects. One such aspect is that in the case of an emergency people should be able to efficiently evacuate the building. In this paper we investigate how the width-profile of a corridor leading to an exit might affect the efficiency of evacuation. We model the dynamics of crowds using a continuum model, leading to a one-dimensional non-linear hype

Insights from experimental hybridization on floral trait inheritance and reproductive isolation in self-compatible and self-incompatible Arabis alpina L. (Brassicaceae)

Hur ärvs blomdoft? Att lukta gott är inte bara viktigt för oss människor. I växternas värld är doft, eller de kemiska doftsignalerna, livsviktigt för att kunna locka till sig pollinatörer eller avskräcka fiender. Vi vet redan mycket om hur insekter reagerar på kemiska signaler från växter och hur doft varierar mellan olika växtarter, men fortfarande väldigt lite om hur blomdoft ärvs inom växtpopuOne of the main challenges in evolutionary ecology is to identify the factors and agents that drive diversification. Two of the most diverse groups of organisms on earth are plants and insects, and evidence strongly suggests that the diversification of both groups is driven by the interactions between them. One fruitful way for understanding how these interactions evolve and diversify is to identi
