Det första skedet när ett byggnadsverk ska uppföras är det konceptuella designskedet, det är här de första besluten om utformningen av byggnadsverket görs. I det traditionella arbetsflödet utformas byggnadsverket först i ett ritprogram, sedan används ett annat datorverktyg för att verifiera att det utformade byggnadsverket kan hantera de krafter som uppstår, t.ex. vind, egentyngd osv. Detta arbeteBefore a new structure can be built, it must be designed. This design phase is a very important step in the building process. The total cost of the structure and its structural performance are largely dependent on the structural design process. The impact of decisions on the design process is initially high and declines as the design matures. However, few computational tools are available for the

The purpose of dynamic asset allocation (DAA) is to overcome the challenge that changing market conditions present to traditional strategic asset allocation by adjusting portfolio weights to take advantage of favorable conditions and reduce potential drawdowns. This article proposes a new approach to DAA that is based on detection of change points without fitting a model with a fixed number of reg

Purpose – The purpose of this paper is to explore, illustrate, and conceptualize how sustainability service is performed and the role it plays in the promotion of sustainable consumption. Design/methodology/approach – Theoretically, this paper takes a practice theory approach, conceptualizing the provision of sustainability service as a set of complex, socio-material, and performative practices.

Report on the medieval parish church of Stora Köpinge in Scania, Sweden. The report is part of a never fullfiled plan of publishing short building archaeological reports on all the medieval churches of the two counties Ljunits and Herrestad at Ystad in Scania as part. The investigation was conducted as a part of the research project "The Cultural Landscape during 6000 years in Southern Sweden", al

Katedralen var en av de mest centrala institutionerna i det medeltida samhället. Kring stiftets biskop samlades den kyrkliga makten och dåtidens elit, dygnet runt firades gudstjänster och här utbildades stiftets präster. En viktig roll för livet i och kring katedralen hade domkapitlet eller katedralkapitlet, dvs det organiserade prästerskap som betjänade domkyrkan och bistod biskopen.I mitt avhandThe cathedral was one of the most important institutions in medieval Europe. The local as well as ecclesiastical elite gathered around it and its bishop; the liturgy was celebrated day and night, year after year; the cathedral served as educational institution of the clergy. The cathedral chapter, i.e. the organized clergy that served at the cathedral, played a decisive part in all this.The overar

Kolhydratsystem så som alkylglycosider, cellulosa och cyklodextrin är miljövänliga förnybara material som används inom många områden i dagens samhälle; som bärare av aktiva substanser i läkemedelstabletter, matsmältningsfiber, papper, kosmetika och hygienartiklar för att nämna några. De är fasta substanser uppbyggda av molekyler ordnade i en viss struktur. Med tiden, och eventuell yttre påverkan, In the solid state, molecules are normally ordered in a specific structure. With time, and as a result of influence from the surroundings, solid materials can change their molecular and/or crystal structure and, as a consequence, obtain completely different properties. Water is particularly important in this respect. Adsorption of minuscule amounts of water from the atmosphere may have huge effect

Putting climate change policy-integration into practice is challenged by problems of institutional misfit,due to, inter alia, deficient vertical administrative interplay. While most focus within the field of climatechange research has targeted the national–local interplay, less is known about the interface of regionaland local perspectives. Here, the aim is to study that interface with a specific

Kisel är ett vanligt förekommande grundämne som gärna bildar en oxid, nämligen kiseldioxid. Kiseldioxid träffar man i hög utsträckning på i det dagliga livet. Det är nämligen huvudbeståndsdelen i sand, glasvaror, kvarts, många keramiska material men också i den färgskiftande ädelstenen opal. Det finns också flera grupper av porösa kiseldioxidmaterial, till exempel så kallade zeoliter som har myckeThe formation process of porous silica materials is an intricate process, involving a number of components that interact to form a highly organized material. Both zeolites and mesoporous silica materials typically require the presence of organic structure director agents (SDAs) around which the silica network polymerizes. For zeolites the SDAs are molecular and for mesoporous silica the SDAs assem

I denna rapport analyseras effekterna av sänkta parkeringsnormer för bostäder för invånarna i det centrumnära, och relativt nybyggda, bostadsområdet Porslinsfabriken i Göteborg. Porslinsfabriken är med en relativt låg parkeringsnorm på 0,57 platser per lägenhet ett bra exempel på en parkeringspolitik som förs i alltfler kommuner. Resultatet visar att 19 procent av hushållen har minskat bilinnehaveThis report analyses the effects of lowered parking requirements for residents in the centrally located, relatively newly built housing area, Porslinsfabriken in Gothenburg. Porslinsfabriken has a relatively low parking requirement of 0.57 places per apartment and is a good example of a parking policy being introduced in many Swedish municipalities. The results show that 19 percent of households h

Landskapets geologi, former och andra naturgivna egenskaper har en förhållandevis undanskymd roll i dagens infrastrukturplanering jämfört med den vikt som läggs vid biologiska och ekologiska företeelser och egenskaper. Många gånger är det dessutom endast extremföreteelser som lyfts fram i samband med infrastrukturplaneringen medan det så kallade vardagslandskapet får träda tillbaka, trots att det

Short presentation of medieval archaeology at the crossroad of different methodological perspectives.

Aim: Hearing loss (as reflected by abnormal sound detection) is a frequently reported consequence of Type 1 diabetes mellitus. We sought to evaluate sound detection, auditory neural function and binaural processing ability in a group of school-aged participants with Type 1 diabetes and to assess their functional hearing and general communication ability. Methods: A range of electroacoustic, electr

Background: Older people with cognitive impairment represent a large group of patients in acute care settings. Research show that these acute care environments can be unsafe and even unfriendly for frail older patients. Research and clinical experience show that being a nurse in acute/specialised medical facilities means to work in a high-speed, technologically complex and demanding environment. W

Many popular first order algorithms for convex optimization, such as forward-backward splitting, Douglas-Rachford splitting, and the alternating direction method of multipliers (ADMM), can be formulated as averaged iteration of a nonexpansive mapping. In this paper we propose a line search for averaged iteration that preserves the theoretical convergence guarantee, while often accelerating practic
