In modern chemical process industry, process state transitions, orgrade changes, are common operations. For example, for a papermachine, a common operation is to change the surface weight of theproduced paper. In this case it is of importance that the transitionto the new grade is done fast, but without a breakdown asa result. This paper addresses this problem by combining optimizationtechniques a
Flexibla och ekonomiska system för eldrift av vägfordon är ett område med aktiv utveckling och forskning. Denna rapport tillämpar sådana system för drift av alla stadsbussar i Lund. En programvara för simulering och ekonomisk optimering av sådana system har utvecklats och några systemkonstruktioner presenteras. Ett försök till realistiska kostnader och resultat uppskattningar av de viktigaste kompFlexible and economic systems for full electric operation of road vehicles are an area of intense research and development. This report applies such systems to the operation of all city buses in Lund. Software for simulation and economic optimization of such systems is developed and a few system designs are presented. An attempt to a realistic cost and performance estimate of the main components i

Green products are becoming part of contemporary consumer cultures and part of everyday life. But how are green products constructed? And how do they work? This paper is concerned with the role that marketing plays in the making and circulation of green products. My aim is to illuminate the process of green making. Departing from an understanding of marketing as socio- material practice I analyse
Vi löper ofta risker som vi inte tar. Och vi vet ofta litet om de situationer där vi tar risker. Dessa två iakttagelser utgör den här bokens utgångspunkter. Det är utgångspunkter som inte passar så väl ihop med mycket annat som vi brukar ta för givet i risksammanhang. Läsaren får därför många tillfällen att ompröva sin syn på saker som skillnaden mellan fara och risk, vad ett riskobjekt är och vad
In trying to get products out to market, manufacturers of FMCG (Fast Moving Consumer Goods) differentiate themselves through e.g. promotional efforts and display packaging (Point-of-Purchase packaging). For the display packaging, companies turn to contract packagers who are able to supply this service, providing the design, manufacturing and assembly and packing of the display packaging. This pape
This book examines some of the economic, political and social issues facing the Scandinavian countries of Sweden, Finland, Norway and Denmark. Topics discussed in this compilation include Denmark's energy sector transition toward agro-biomass; Sweden's exchange-rate volatility trade with Germany; Norwegian quota reform in gender corporate representation; legislation, culture and development of qua
Purpose: Supply chain efficiency (economic and ecological) is affected by packaging design. The purpose of this research is to investigate how integrated approaches aiming for ecoefficient supply chains are used in packaging development processes and how a set of preselected factors influences the adaption of more or less integrated approaches at companies. Design/methodology/approach: The researc
Popular Abstract in Swedish Richard Hughes (1900-1976) blev mycket känd genom sin debutroman A High Wind in Jamaica, 1929. Han förhastade sig inte med nästa roman, In Hazard; den kom först 1938. Intervallerna blev allt längre. The Fox in the Attic från 1961 inledde hans romancykel The Human Predicament, och fortsättningen kom med The Wooden Shepherdess 1973. Av en planerad tredje del publicerades The two last novels by Richard Hughes (1900-1976), the first in his planned The Human Predicament series, are partly set in Germany in the years between the First and the Second World War. Much of the action in The Fox in the Attic (1961) takes part in and around Munich, culminating in a fictional reconstruction of the so-called Hitler Putsch on November 8-9, 1923, the future dictator's aborted ea
Thin films of crystalline mesoporous cerium dioxide were prepared by using a template of a copolymer surfactant (Pluronics 123) at ambient conditions in ethanol. The synthesised ceria was produced via a direct calcination step, without using a gelling stage. The precipitated CeO2 matrix was crystalline with a high surface area. The solution height over the synthesis vessel before the ca
This dissertation has three cornerstones: * Haptics * Human-Computer Interaction (HCI) * Blind Users Haptics deals with controlling human movements and getting feedback through the sense of touch. A haptic interface transmits forces to a person’s hand or fingers in a way that mimics the sensation of touching real objects. Virtual haptic touch can be particularly useful for people with visual i
Mobility Management (MM) syftar till att främja hållbara transporter och minska resandet med bil genom att förändra resenärers attityder och beteenden. Denna rapport är framförallt ett underlag inför framtida satsningar på MM-åtgärder i Lund och Helsingborg. Detta är ingen före-efter analys då det i nuläget inte finns material för att göra en sådan studie. Istället kan rapporten användas för en fr
Popular Abstract in Swedish Den enorma variationen av beteenden och utseenden som återfinns i djurriket har i alla år fascinerat och länge förbryllat biologer. Rovdjurens skoningslösa utgallring är en av de stora drivkrafterna bakom evolutionen av alla dessa karaktärsdrag. Rovdjuren är såklart även en viktig strukturerande kraft i sötvattensmiljöer och har där lett till utvecklingen av mängder av The varieties of prey phenotypes that have been revealed in nature are vast and many of these phenotypes are the result of the selective force that predators have had on prey traits in the past. Even within species and populations we see variations due to both differences in the selection forces they live under but also due to individual trait variation. In this thesis I investigate both the direc
