Ekerö Trappräcke

Persson, Jonas, Tasevski, Alexander January 2014 (has links)
Detta examensarbete omfattar 15 högskolepoäng och skrivs på Mälardalens Högskola i Eskilstuna med inriktning produktdesign – industriell design. Arbetet genomfördes under vårterminen, april till juni 2014 där en grupp på två personer utvecklade ett trappräcke på Lundbergs produkter AB i Nyköping. Lundbergs tog kontakt med gruppen innan start och presenterade fyra stycken uppdrag. Uppdraget var att utveckla Ekerö räcke i metall, där målet var att få räcket monterbart i trappor och gruppen blev tilldelad en kravspecifikation på vad företaget förväntade sig utav slutprodukten. På grund av den stora säkerhetsfrågan hos ett trappräcke behövdes en analys på problemet och de krav som ställdes på produkten. Gruppen började med att undersöka hur en trappa kunde vara konstruerad för att senare kunna sätta krav på trappräckets utformning. Eftersom det finns så många komponenter på den befintliga produkten så uppstod det många problem när räcket monterades i en vinklad konstruktion. Dessa problem dokumenterades och samlades ihop i olika kategorier så att gruppen senare kunde fokusera på varje område i idégenereringen. I kravspecifikationen var ett av kraven att följa boverkets regler angående trappräckesbyggen. Efter en sammanställning av boverkets regler så hade gruppen tillräckligt med material för att göra en idégenerering. I nästa skede påbörjades idégenerering med hjälp av metoden Brain Writing. Gruppen fokuserade på varje område var för sig där en större mängd idéer blev till ett fåtal som kom att kallas koncept. Med hjälp av verktyg som Pughs matris och QFD samt företagets tankar så uteslöts vissa koncept och andra vidareutvecklades. Efter att ha utvecklat två större koncept av tretton mindre så presenterade gruppen dem för uppdragsgivaren. Mötet resulterade i en kombination av båda koncepten så kunden får möjligheten att montera efter sitt egna val. När slutkonceptet var bestämt började gruppen tillverka en prototyp i skala 1:1 med hjälp av 3d-skrivare samt trä- och metallverkstaden. När gruppen arbetade på prototypen upptäcktes en risk där ett av koncepten lätt gick sönder vid montering. Då valdes koncept 1B istället för koncept 1C. Examensarbetet resulterade i en produkt som efterliknade Ekerö räcke i metall, som dessutom har många möjligheter att anpassas efter kundens krav, önskemål och kreativitet. / <p>Detta examensarbete är konversiellt, vilket är anledningen till de censurerade bilderna.</p>

Borg, berg och bygd. : Selaötraktens fornborgar under den mellersta järnåldern.

Pilgren, Ludvig January 2013 (has links)
This paper deals with hill-forts located on and directly south of Selaön, in the center of Mälardalen, Södermanland, dated to the late roman period and the migration period. Of special interest is differences and similarities between the forts when it comes to their morphology and the hills where they were built. Furthermore, their landscape has been examined and I have tried to put the hill-forts in relation to any iron age settlements.

Att stanna eller flytta? : Kontinuitet och diskontinuitet i det uppländska kulturlandskapet mellan mellersta och yngre järnåldern / To Stay or to Leave? : Continuity and Discontinuity in the Cultural Landscape of Uppland during the Transition between the Middle and Late Swedish Iron Age

Jansson, Fredrik January 2020 (has links)
This paper studies continuity and discontinuity in the eastern Mälaren valley during the transition between the middle and late periods of the Swedish Iron Age. Historically this period has been seen as a period of population decline and turbulence but newer research has questioned this premise. In the areas studied in this paper one showed signs of discontinuity whereas the other seemed to have expanded. The discontinuity could possibly be explained with tectonic uplift causing the waterways over time to become non-traversable. Furthermore I could show a potential link between high status settlements and control over important paths for communication over water.

Järnåldersboplatser och historiska byar : En studie av agrara bebyggelsemönster i mälarbygder under 1500 år

Håga in context – An analysis of the Håga complex in the Bronze Age landscape of the Mälar Valley region / Håga i kontext – En analys av Hågakomplexet i bronsålderslandskapet i Mälardalen

Elliott, Rachel January 2020 (has links)
The Bronze Age in Middle Sweden is characterized by several key sites and monuments which have been interpreted by previous research to play an overarching role in the elite ruling system in the Mälar Valley region. King Björn’s mound (a.k.a. the Håga mound) and the hillfort Predikstolen represent one of these complexes and has been referred to as a central hub for trading between the south and east as well as a central meeting point for alliance networks throughout the Mälar Valley region. The ritual importance of the site has been particularly relevant to discussions around the mound and accompanying cult house, Hågakyrkan, since the excavation of the mound in 1902-3 by Oscar Almgren. The investigation of the mound’s central cairn dated the monument to the Bronze Age Period IV, and resulted in the discovery of one of the most spectacular burials in Sweden, including gold and bronze artefacts indicative of connections with south Scandinavia, particularly Denmark, and a ritual role typified by Kristian Kristiansen’s institutional divisions of elites based on artefact assemblages. To understand how Håga and other Bronze Age sites have attained the label of ‘ritual’ places in the landscape, a discussion is included on previous research which has defined the parameters of sacred versus profane activity utilizing theories on identity as demonstrated through material expression explored by Kristian Kristiansen (1987, 2011) and Susanne Thedéen (2004). This thesis also utilizes the ritual practice theory defined by Catherine Bell (2009) to identify the repetitive traditions which define cultic practice during the Bronze Age in Middle Sweden in order to understand the unique phenomenon of Håga as compared to other sites in the Mälar Valley region: two sites with established cultic complexes (Broby and Skeke), and two sites characterized by industrial bronze production (Apalle and Hallunda). These sites were additionally chosen based on their position along a north-south inlet system which directly connected Lake Mälaren from the eastern Baltic sea to south Scandinavia and north-western Europe. A comparative analysis of the relevant features and finds of each site as well as a brief overview of the evidence of conflict in southern Scandinavia and Europe are used to contextualize the role Håga served leading up to and following construction of the Håga mound. The delimitations and potential uses of the results are included in the discussion / Bronsåldern i Mellansverige kännetecknas av några nyckelplatser och monument vilka tidigare har tolkats av forskare att ha spelat en övergripande roll för hövdingadömet i Mälardalsområdet. Kung Björns hög (s.k. Hågahögen) och fornborgen Predikstolen utgör ett av dessa komplex och har kallats ett regionalt nav för handel mellan söder och öster, samt en central mötesplats för alliansnätverk i hela Mälardalen. Den rituella vikten har också påpekats som relevant till diskussionen kring Hågahögen och närliggande kulthuset Hågakyrkan sedan undersökningen ledd av Oscar Almgren år 1902-3. Undersökningen av högens centralrösen har daterat monumenten till bronsåldern Period IV och resulterade i upptäckande av en av de mest spektakulära begravningarna i Sverige, vilket inkluderade guld och bronsartefakter som ger indikationer på kopplingar till Sydskandinavien, speciellt Danmark, och den rituella rollen representerat av Kristian Kristiansens institutionella uppdelningar av eliter baserad på artefaktgrupper. För att förstå hur Håga och andra bronsåldersfornlämningar har märkts som ‘rituella’ platser i landskapet, diskuteras tidigare forskning som har definierat begränsningarna av sakral jämfört profan aktivitet med hjälp av teorier om identitet baserad på materiella uttryck utforskat av Kristian Kristiansen (1987, 2011) och Susanne Thedéen (2004). Uppsatsen använder sig också av rituellpraktiksteori eller s.k. ‘ritual practice theory’ definierad av Catherine Bell (2009) för att identifiera återkommande traditionerna som exemplifierar kultpraxis under bronsåldern i Mellansverige, för att kunna förstå den unika karaktär Håga har jämfört andra fornlämningar i Mälardalen: två fornlämningar med etablerade kultkomplex (Broby och Skeke) och två kännetecknade av industriell bronsproduktion (Apalle och Hallunda). De fornlämningar som har valts ut för jämförelse har också baserats på deras position längst det nord-sydliga vattenledssystemet som direkt kopplar Mälaren från Östersjön till Sydskandinavien och nordvästra Europa. En jämförande analys av relevanta anläggningar och fynd från varje fornlämning plus en kort översikt av bevisen för konflikt i Sydskandinavien och Europa används för att kontextualisera Hågas roll innan och efter byggandet av Hågahögen. Begränsningar och potentiella användingsområden av resultaten inkluderas i diskussionen.

I bronsålderns gränsland : Uppland och frågan om östliga kontakter

Ojala, Karin January 2016 (has links)
In archaeological research, the province of Uppland has often been viewed as the northern ‘periphery’ of the Nordic Bronze Age region. At the same time, many researchers have also emphasized the distinctive and ‘independent’ regional character of Uppland and northern Mälardalen. Throughout the twentieth century, Late Bronze Age contacts between Uppland and areas to the east – especially Finland, the Baltic countries and Russia – were much discussed and played an important role in the creation of Mälardalen as a distinctive Bronze Age region. This dissertation examines how images of the Late Bronze Age in the Mälardalen region, more specifically Uppland, have been formed from the late nineteenth century until today, and how views on eastern contacts have affected interpretations of Bronze Age Uppland. The study consists of three parts: 1) A critical discussion on political dimensions of archaeology and archaeological concepts of contact, interaction, similarity and difference, with a special focus on Bronze Age research. 2) A historical examination of representations of the Late Bronze Age in Mälardalen and Uppland, including a discussion about contacts with northern Sweden and a case study of Broby, a Late Bronze Age site near Uppsala. 3) An analysis of debates on contacts between Mälardalen and areas further to the east, through case studies of bronze axes, so-called Mälar celts and Ananino celts, ceramics and inhumation burials. In the analysis, special focus is placed on the Volga-Kama region in Russia and archaeological research in Russia and the Soviet Union. The study shows that discussions on contacts and interaction between ‘East’ and ‘West’ have, in many ways, been affected by the changing political situation during the twentieth and early twenty-first centuries. Knowledge about archaeological research in Russia and the Soviet Union has been very limited among archaeologists in Sweden. In order to further investigate the character and importance of eastern contacts during the Late Bronze Age, more collaboration and exchange between researchers in the different countries is needed. Furthermore, in order to better understand eastern contacts, it is also necessary to investigate in greater depth the relations between Mälardalen and northern Sweden.

Subliminal priming : Manipulation till att välja en specifik kulör på plastpåse / Subliminal priming : Manipulation to choose a specific colour on a plastic bag

Nordberg, Rickard January 2014 (has links)
Primad information är lättare tillgängligt i minnet och kan således lättare bli igenkänt. Förutsättningar för priming är bland annat subliminal perception, mål, tillförlitlighet, icke vaksamt och icke vanemässigt. Studiens syfte är att få bredare förståelse gällande subliminal primings påverkan. Frågeställningen var om kunder i en affär kan manipuleras, primas, till att ta en specifik kulör på plastpåse vid kassan samt om det finns någon könsskillnad vid effekten av priming. Deltagarna var 490 kunder, varav 333 män. Två olika skyltar med olika kulörer placerades vid kassan. Det noterades om kunderna valde den primade kulören på plastpåse eller inte. Kontrollgruppen bestod av 117 personer och dessa fick inte se någon skylt. Resultatet visade en signifikant skillnad, deltagarna valde samma kulör på plastpåse som skylten. Inga könsskillnader påträffades. Forskning visar att primingeffekter kan motstridas genom att individen gör sig medveten av potentiell omedveten påverkan. / Primed information is more accessible in memory and can thus easily be recognized. Prerequisites for priming include subliminal perception, goals, reliability, non alert and non habitually. The study aims to gain broader understanding regarding subliminal primings influence. The purpose of this thesis was to see whether the customers in a store could be manipulated, primed, to take a specific colour on plastic bags at checkout and if there are any gender differences in the effect of priming. Participants were 490 customers, of whom 333 men. Two different signs with different colours were placed at the checkout. It was noted if customers chose the primed colour of the plastic bag or not. The results showed a significant difference, the participants chose the same colour on the plastic bag as the sign. No gender differences were found. Research shows that priming effects can be opposed if people make themselves aware of potential unconscious influences.

Ring Out Your Dead : Distribution, form, and function of iron amulets in the late Iron Age grave fields of Lovö

Mattsson McGinnis, Meghan January 2016 (has links)
The purpose of this study is to analyze the distribution, forms, and function(s) of iron amulets deposited in the late Iron Age gravefields of Lovö, with the goal of ascertaining how (and so far as possible why) these objects were utilized in rituals carried out during and after burials. Particular emphasis is given to re-interpreting the largest group of iron amulets, the iron amulet rings, in a more relational and practice-focused way than has heretofore been attempted. By framing burial analyses, questions of typology, and evidence of ritualized actions in comparison with what is known of other cult sites in Mälardalen specifically– and theorized about the cognitive landscape(s) of late Iron Age Scandinavia generally– a picture of iron amulets as inscribed objects made to act as catalytic, protective, and mediating agents is brought to light.

Sverige 2112 : Ett narrativ om hur arkitekturen kan utvecklas om världen går igenom stora förändringar på grund av klimatförändringarna. En linjär och vertikal stad. / Sweden 2112 : A narrative of how architecture could be developed if the world is going through major changes due to the climate changes. The wall city.

Eliasson, David January 2012 (has links)
Om världen till följd av klimatförändringarna blir mycket varmare kommer förutsättningarna för hur vi planerar städer, infrastruktur och jordbruk helt att vändas upp och ner. De delar av världen som idag står för världens livsmedelsproduktion kommer vid bara några graders förändring bli obrukbara som betes och odlingsmark. Dessa förändringar kan komma att starta konflikter, och stora flyktingströmmar som tillsammans med förändrade klimatzoner helt kommer att rita om världskartan. i Skandinavien är det då troligt att vi behöver bygga samhällen och städer för miljontals nya immigranter, och detta samtidigt som vi befinner oss mitt i den mest fruktbara jordbruksmarken i världen. Om hundra år måste vi dessutom, oavsett detta, dubbla livsmedelsproduktionen globalt sett. Vårt samhälle blir allt mer rörligt och infrastrukturen utvecklas i allt snabbare takt. Tåget, bilen och flyget har alla förändrat världen och staden, och i framtiden kommer vi kanske förflytta oss med nya typer av till exempel supersnabbtåg. De kommer ge avstånd en allt mindre betydelse. Om vi använder oss av de förutsättningar en sådan ny infrastruktur ger, och bygger både horisontellt och vertikalt uppstår en ny typologi för staden. Stannar man vid detta inser man snart att det är en hissnande tanke, och det är just det som detta examensarbete  undersöker. Ett narrativt projekt som spekulerar i frågan om det här händer, kan då också det här hända? / If the world as a result of the climate changes will be much warmer, the conditions for how we plan cities, infrastructure and agriculture will be completely turned upside down. Parts of the world which today account for the world's food production will at just a few degrees of temperature change become unusable for cultivation. These changes may result in conflicts, and massive refugee flows. Changes of the climate zones will completely redraw the map of the world. In Scandinavia, is it likely that we will need to build societies and cities for millions of new immigrants. At the same moment Scandinavian countries are in the midst of the most fertile farmland in the world. And also, in one hundred years we must, notwithstanding this, double our food production globally. Our society gets more and more mobile and the infrastructure is developing more and more. The train, the car and the airplane as concepts have all changed the world and the cities when they where introduced. The future, might move us towards new types of super-fast speed trains that will give an even smaller importance to distances. And if we use the textures of these new infrastructures, it might lead us to build both horizontally and vertically. Then it appears a new type of typology of cities. If you stay at this thought, you realize that it is completely staggering, and that is exactly what the thesis project investigates. It is a narrative project that speculates on the question; "If this happens, might then also this happen?"
