This paper describes a new hardware architecture for binary image erosion and dilation. The design is to be used in a self contained real-time surveillance system. Thus, low complexity and low power consumption are main constraints. To achieve this goal the aim has been to reduce memory requirements and the number of memory accesses per pixel. By storing only the number of consecutive ones that ap

Under hösten 2012 och vintern 2013 ansvarade Stefan Larsson och Per Runeson för en tvärvetenskaplig studiegrupp om Det digitala samhället på Pufendorfinstitutet vid Lunds universitet. Vid sex seminarietillfällen under hösten 2012 och början av 2013 träffades 17 forskare från sex fakulteter, en eftermiddag, var tredje vecka för att få olika perspektiv att mötas och konfronteras kring aspekter på de

In fire safety engineering, information about the expected walking speed of occupants through smoke is one factor that is of great interest to the designer. However, despite the fact that research already in the 1970s demonstrated that people tend to evacuate through smoke, little research has been performed on the topic, and evidently there is a lack of data on walking speed in smoke. This has cr

Natural food webs are embedded in a variable environment, which causes population densities to fluctuate, despite a potential stable equilibrium. Population interactions as well as the characteristics of the environmental fluctuations determine the resulting population dynamics. Populations sensitive to the same kind of environmental disturbances will show correlated responses in their respective

This paper reports on an inquiry into the use of metadata, publishing formats, and markup in editor-managed open access journals. It builds on findings from a study of the document architectures of open access journals, conducted through a survey of 265 journal web sites and a qualitative, descriptive analysis of 4 journal web sites. The journals’ choices of publishing formats and the consistency

Of the many ways hydrogen can be produced, this chapter focuses on biological hydrogen production 12 by thermophilic bacteria and archaea in dark fermentations. The thermophiles are held as promising candidates 13 for a cost-effective fermentation process, because of their relatively high yields and broad substrate palette. Yet 14 many challenges remain to be faced, including improving productivit

Kapitlet utgår ifrån den tidigare modernitetens manifestationer av Durkheims "organisk solidaritet", de former av Gemeinschaft som mest typiskt utvecklades i småstaden vid tiden för Gesellschafts genombrott, där de lyckades hålla samman i grunden splittrade kollektiv. Mot bakgrund av aktuell empiri diskuteras sedan konsekvenserna av dessa gemenskapers upplösnng för människor i vår egen tid. Dessa

Today we use products to shape our identity, by communicating to others who we are and what we want to be. Using products for communication of identity seems especially important for young adults. Persons with disabilities live with double identities. Sometimes it is important to be a person with a disability (e.g., someone in contact with health care and other welfare systems in society), while a

Popular Abstract in Swedish Stärkelsemikrosfärer undersökta i denna avhandling är avsedda för kontrollerad tillförsel av läkemedel som utförs i form av depåpreparat eller slow release-former. Stärkelsemikrosfär är en beredningsform anpassad för inkapsling av protein i terapeutiskt syfte. För att uppnå en kontrollerad frisättning kan stärkelsemikrosfärer täckas av poly (DL-lactide-co-glycolide) (PStarch microsphere is a dosage form suitable for the encapsulation of protein drugs. The starch microspheres investigated in this thesis are intended for release of the drug in a pre-designed way, or in controlled manner. For this purpose the starch microspheres can be coated by poly(DL-lactide-co-glycolide) (PLG) film, which is a release controlling. The term microsphere quality is complicated an

Background The plant respiratory chain contains several energy-dissipating enzymes, these being type II NAD(P)H dehydrogenases and the alternative oxidase, not present in mammals. The physiological functions of type II NAD(P)H dehydrogenases are largely unclear and little is known about their responses to stress. In this investigation, potato plants (Solanum tuberosum L., cv. Desiree) were sprayed
