Citybanan på rätt spår? : En fallstudie om maktstrukturerna i processen runt Citybanan

KORTFATTAD SAMMANFATTNING Bristen på spårkapacitet genom centrala Stockholm har länge varit ett stort problem och om ingen förbättring sker, väntas situationen bli ohållbar. I uppsatsen undersöks de underliggande maktstrukturerna i planeringsprocessen genom en fallstudie av Citybanan som är en sex kilometer lång pendeltågstunnel i Stockholm. Temat för uppsatsen är stora planeringsprojekt, där utgångspunkten är överskridelser av tidsramar och kostnader. Ett sätt att undvika detta är att göra tillförlitliga prognoser. För att åskådliggöra strukturerna i beslutsprocessen tillämpas en narrativ metod, där kronologi används för att förtydliga händelseförloppet runt Citybanan.

Råvaruinflöde inom träindustrin : En fallstudie på ett norrländskt pappersbruk

Today's global market means that raw materials are sought and bought from all over the world. This creates an higher demand for a well-functioning supply chain. In our thesis we have studied a large paper mill in northen Sweden which experiences issues with flow of raw material. Our aim has hence been to examine which aspects affect the flow of raw materials to the mill, and how these can be adressed using an IT-system. The question we sought to answer was; What factors are important to consider and how do these affect the ability of an IT-system which will support the flow of raw material at the paper mill? We have found that the problems are strongly connected to the low amount of information sharing between the mill and the suppliers.

Bangårdområdet : Sundsvalls nya stadsdel

Det pågår ständigt förändringar i samhällsstrukturen som får effekter på många olika nivåer. Det har skett en övergång från jordbrukssamhälle till industrisamhälle och till kunskapssamhälle. Industriarbetarnas andel av befolkningen minskar till förmån för kunskaps- och servicebaserad verksamhet. Parallellt med denna utveckling har industrin lämnat efter sig stora landsarealer som är välförsedd med infrastruktur. På många platser runt om är det idag vanligt att mark i staden blir tillgänglig på grund av industrins strukturomvandlingar.

The principal was the projectSåNätt, in which the main participant was Volvo Cars Corp. In consultation with a reference group, consisting of delegates from the industry and KTH, a specification of requirements was produced.

Returhantering vid LensLogistics AB: en process- och
flödesutredning för förbättringar

Return handling is often regarded as a slow and complex process. Studies have shown that it is not unusual for a return to cost up to nine times as much as a standard outbound delivery. An efficient return handling process is therefore essential to all competitive companies dealing with logistics. This report investigates, analyzes and gives suggestions on development with the purpose to improve the return handling process at LensLogistics AB in Kista, north of Stockholm, Sweden. The study has been conducted from a deliberately practical point of view in order to suggest improvement suggestions possible to implement and thereby change the entire return handling process.

Grad av nöjdhet och ökad livskvalitet hos uni- respektive bilaterala hörapparatanvändare

Andelen  äldre  i Sverige  ökar. Hos normalhörande  äldre människor  sker  det  en  förändring  i taluppfattningen som är en del av det naturliga åldrandet. Syftet med denna studie är att belysa det  biologiska  åldrandets  påverkan  på  den  åldrande  individens  taluppfattningsförmåga.  En systematisk  litteraturstudie  har  använts  som  metod.  Resultatet  från  övervägande  delen  av använda  artiklar  i  denna  studie  visar  att  normalhörande  äldre  har  sämre  taluppfattning  än normalhörande  yngre.  Den  försämrade  taluppfattningen  är  enligt  artiklarna  ett  resultat  av förändringar i det centrala hörselsystemet. Artiklarna pekar på att dessa förändringar beror på förändrad  lateralisering,  förlångsammad  kodning  av  talsignalen, minskad  nervaktivitet  eller förtvinade nerver i hörselkortex..

Framtagning av en utvecklingsprocess för automation - baserat på konceptet Lean Automation

Due to the globalization today the competition in the market has in- creased and it requires flexibility and produce according to customer demand. In order to reduce the cost of wages industrial companies are now considering moving the manufacturing to low-cost countries. To keep up with the competition in the market without moving the manu- facturing abroad, Lean Automation was developed. The concept of Lean Automation is to reduce the perceived complexity with automa- tion and make automation available for new users and in new applica- tions.Haldex Brake Products are situated in Sweden and want to maintain the manufacturing of the automatic brake adjusters in the country. It is a product well-known and highly exposed to the competition in the mar- ket.

Underröjning i förstagallring :

This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The work was an assignment from Sydved and the aim of the work was to investigate the economical output of removing understorey trees before first thinning. Four treatments were studied. - no cleaning before thinning - cleaning of all trees less than DBH 5 cm before thinning - cleaning of all trees less than DBH 7 cm before thinning - cleaning of all trees less then DBH 9 cm before thinning The result shows a decrease of the cost per m3 for the harvester with about 38% if all trees less than DBH 9 cm was cleaned before thinning compared with the un-cleaned area. At the same time the total net revenue increases with about 22%. .

Stadens förändrade funktion - En ideologikritisk studie av Göteborgs översiktliga planering mellan 1959 och 2011

Den här magisteruppsatsen i kulturstudier är en ideologikritisk analys av Göteborgsstadsplaneringsidelogi mellan 1959 och 2011. Den huvudsakliga frågeställningen är hurskillnaden mellan efterkrigstidens- och dagens stadsbyggandsideologi kan förstås? Med hjälpav Karl Marx värdeteori om kapitalet undersöks de materiella betingelserna förstadsbyggnadsideologins förändrade förhållande.Studien argumenterar för att efterkrigstidens stadsbyggnad helt och hållet anpassades efterden tunga tillverkningsindustrins behov av arbetskraft och infrastruktur. Men också till dentillströmmande arbetarklassens högre krav på levnadsstandard. I analysen av nutidastadsplaneringsideologi pekar studien på förändrade förutsättningar såsom anpassning tillglobal arbetsdelning och ränteorienterat kapital.

Solel från ljudbarriär : längs Annetorpsvägen i Hyllie, Malmö

City of Malmö has ambitions for the district Hyllie to become a demonstrative area ofsustainable urban development. As a part of this the following report aims to investigate the potential in using noise barriers combined with photovoltaics along Annetorpsvägen to generate solar electricity. To quantify the losses that shadows from buildings along the roadmight cause, a 3D-model of the area was constructed in SketchUp. This digital model made it possible to simulate shadows and how they change over the year. A reference model of a photovoltaic noise barrier (PVNB) was constructed and used to find the dates on which the solar cells are shadowed depending on building heights and positioning of the barrier.The results show that two lengths with a total distance of 400 meters is appropriate for applying photovoltaic noise barriers.

Kreativitet i skolan : funktion och förtjänst

This dissertation examines how creativity can be of benefit for the school. It discusses if there is a need or demand for it and how the present situation is in Swedish schools. Defining creativity accurately is difficult but it is relevant to look at the environments that use creativity. There is a vast amount of literature that uses creativity and it varies to some extent. Creativity originates from meetings and combinations, both within and outside of the individual.

Casemetodik och geografi : En studie av elevers och lärares syn på casemetodik i geografiundervisningen

The case method is a relatively new pedagogical method in Sweden that is based on students exercising their skills in the analysis of complex situations and problems that are based in reality and that help students to see a broader perspective and context.The purpose of this study has been to investigate, through interviews with students and teachers, the advantages and disadvantages of the case method in teaching geography.The results of the study show that both teachers and students share almost the same opinion. The conclusion is that the case method is a didactic method that is well suited for teaching geography, as it is based on reality and develops the students? ability to analyze, argue and find solutions in several areas within the subject of geography. If a student is strong in these skill areas they can really benefit from the application of the case method in the teaching of geography, but for students who are weaker in these skills, the case method can be a disadvantage.

Vardag på ett särskilt boende för en äldre invandrare som inte kan det svenska språket : En observationsstudieAn observation study of the everyday life of an immigrant unable to speak swedish and living in a home for elderly

In Sweden the social assistance from a historical perspective, has been a part of the social legislation, since the 18th century. In that time called poor relief. Through the centuries this has established the social assistance we have today. With focus on the child, we have attempted to illustrate how the social workers consider the child perspective when they are dealing with the social assistance. We wanted to get a view of how the social worker reasons about needs the children have and how they can see that the benefit has been provided for.

Utveckling av heltäckande gångbord

This thesis work is a 30hp D-level assignment in design as a co-operation between MälardalenUniversity and Scania CV AB in Södertälje. The purpose was to develope a close fitted catwalk.The market has seen an increasing value for these types of applications and have the ambition to keep up with the rest of the competitors. The catwalks of todays standards shall be estetical attractive, have a non slippery surface and be costefficient.While working with this project I have spent a lot of time with the concept proposals and with the evaluation of the concepts, resulting in a final CAD model and a approximation of the cost estimate. The new catwalk fulfils all the new recommendations and rules as sharp edges, ADR, the height of the stepup and a non slippery surface with built in drainage..

Geosynteter för hållbara vägar : Modell för jämförelse av vägöverbyggnader med eller utan geotextiler och/eller geonät

The different material layers as part of a road construction fill all a function so theroad becomes durable, safe, comfortable and aesthetically pleasing. Recently, anew group of construction materials started to play an important role in roadconstruction ? geosynthetics.This thesis addresses the two most common types ofgeosynthetics used in modern road construction, namely geogrids and geotextiles.The most common use of geogrids is reinforcement of poor subgrade by usinggeogrid soil reinforcement, which occurs when road material particles wedge inthe geogrid?s mesh. Geotextiles act partly as a barrier that prevents the finermaterial in the below ground from being mixed with coarser upper material andalso act as a load spreader.Road contractors often face a choice of whether geogrids and/or geotextiles areappropriate in a particular road project and also how much profit the choice mightbring. This phase in the tender calculation process is the intended scope of thisthesis.The thesis deals with both the "hard" cost-function aspects and the "softer" values e.g.
