Complex systems can be described by coupling several standalone ODE problems that communicate with input and output signals. The need for simulating such systems has increased in recent years. A major issue when simulating coupled ODE systems has been to communicate coupling relations properly throughout integration and how to handle discontinuities. In this paper a concept that aggregates several
Error control coding is an essential part of any well-designed digital communication system. It has been used in structures to protect the information, by enabling reliable delivery of digital data over unreliable communication channels. Even though this is an old topic, enlisted by Shannon in the late 40's, a lot of research is still going on. There have been recently some interesting approac
The purposes of this master thesis are the simulation of the aerator air flow driven by the spillway water flow in the Bergeforsen dam and the behavior of the flow in the stilling basin. Aerators are employed to supply air at critical locations in the flow where low pressure and cavitation may occur in order to protect the structure. The simulations were carried out, first in 2D and then in 3D, wi
En borrkärna från Anholt (Kattegatt) togs upp under IODP-expedition 347 i Östersjön. Kärnan är daterad till ~18-14 ka BP och representerar deglaciationen i slutet av Weichselistiden. Bentiska foraminiferer av arten Elphidium excavatum clavatum analyserades för stabila isotoper (δ18O och δ13C) för att rekonstruera region-ens paleoklimat och paleoceanografi, såsom salinitet, ventilation och produktiThis thesis is based on a sediment record collected from the Kattegat Sea, southwestern Scandinavia (Anholt Island area) during IODP Expedition 347 in autumn 2013, and focuses on a portion of this record spanning ~18—14 thousand years ago (ka BP), representing the last deglaciation at the end of the Weichselian. Benthic foraminifera of the species Elphidium excavatum clavatum were analysed for sta

Undersökning och hantering av arsenikförorenade brunnar i Nicaragua Arsenik förorenar dricksvatten i Nicaragua och framkallar cancer. Lösningen är enkel: sand, tegelstenar och järnspikar. Varje år dör hundratusentals människor till följd av arsenikförorenat dricksvatten. Världshälsoorganisationen WHO listar arsenik på topp-tio-listan över de kemikalier i världen som hotar människors hälsa mest. The awareness of problems concerning arsenic contaminated drinking water sources has during recent years increased. WHO (World Health Organization) decided in 1993 to lower the recommended limit of arsenic in drinking water from 50 μg/l to 10 μg/l, mainly due to observations of its carcinogenicity. New places where the WHO limit for arsenic is exceeded are constantly discovered all over the world.

The majority of the current 3GPP and M2M networks use or will use IPv6 for accessing the internet. These IPv6 networks use Neighbor Discovery as defined in RFC 4861 to identify their neighbors on the link and see if they are active. The increase in the complexity of wireless networks and introduction of battery operated devices sets forth notable challenges to certain assumptions in the RFC 4861.
This research supports the hypothesis that consultation, team work and congruence is a strategy to reduce risk, and that effective consultation reduces the potential for outrage when things do not go to plan. The research sought the opinion of managers on these matters, and if they were aware of own-biases that undermine the effectiveness in which they engage, and of antidotes to such “hazardous t
There are various ways in which Enterprise Architecture (EA) is defined these days. One of the more common definitions is that EA is a dashboard that allows business architects and other stakeholders to govern an enterprise’s transformation process. This dashboard shows current operations as well as its future and desired state. In theory this might seem as a good tool for enterprise architects bu
Recently a new way of constructing variable step-size multistep methods has been proposed, that parametrizes the entire domain of multistep methods. In the presented work the case of explicit two-step methods is looked at, analyzed and related to the already known theory of multistep methods. The error coefficient is derived as a function of the step-size ratio and an upper limit to the method dom
Product Service Systems offer companies the possibility to reduce environmental impacts by diminishing resource consumption, raw material extraction and waste generation. The concept focuses on a system of products, services and supporting networks with the aim of transitioning from selling the benefits of a product rather than the actual product. Naturally, incentives are created for companies to
Bakgrund: Förändringar innebär risker för företagen, ett sätt att minska dessa risker och öka chanserna att det lyckas är att hantera det motstånd som dyker upp. Syfte: Med utgångspunkt i kommunikativt handlande genomföra en analys av relationen mellan ledarskap och förändringsmotstånd samt diskutera vikten av hantering av förändringsmotstånd. Metod: En teoretisk studie med viss hjälp av hermeneut
I Sverige finns det nästan dubbelt så många manliga som kvinnliga chefer. I den transport- och logistikkoncern vi har valt att undersöka är det endast 15 procent kvinnliga chefer. Syftet med vår studie är att utifrån tidigare teorier undersöka och förstå de kvinnliga medarbetarnas inställning till att inta chefsbefattningar och de kvinnliga chefernas erfarenheter av sitt chefskap i organisationen.
Detta arbete är en förkortad version av originalarbetet. För information om originalarbetet kontakta författaren. Räddningstjänsten kan använda sig av aktionsforskning som en mall för ett systematiskt arbete för att ta vara på erfarenheter. För arbetet mot en lärande organisation kombineras aktionsforskning förslagsvis med fallstudier efter devisen fånga, förankra och förändra. På grund av aktio
Fenomenet som avses studeras i denna kandidatuppsats är arbetsplatslärande och studiens syfte är att beskriva och analysera personalvetares uppfattade arbetsplatslärande samt diskutera värdet av att detta lärande utvecklas. Studiens metodologiska ansats är fenomenografi och det empiriska materialet har därmed samlats in genom semistrukturerade intervjuer med åtta yrkesverksamma personal-vetare.
The aim of this thesis is to understand how the feeling of home can appear in a youth care institution for unaccompanied children. Unlike other youth care institutions that deals with psychosocial problems, these youth cares become more permanent to unaccompanied children. The study is made from qualitative approach, with ethnographic studies at a youth care for unaccompanied children. The observa
