Om kritik : en lägesrapport från den svenska landskapsarkitekturkritiken

How does the criticism of landscape architecture in Swedish professional journals look today? Does it exist at all? What is criticism and what is its purpose? These questions have been the starting point for this degree project. I have found a lot of different answers among journals, books and websites, as well as in interviews with five persons that all have a relation to the landscape architecture criticism in different ways. These answers may look a bit disjointed at first, but are at a closer examination pointing in the same direction ? that the criticism of landscape architecture projects hardly exists today.

Att implementera Service Oriented Architecture kostnadseffektivt

I enighet med teknikutvecklingen förändras även förutsättningarna för kostnadseffektiva IT-miljöer. Systemarkitekturen för mjukvarusystem förändras i samband med detta och verksamhetens systemdesign måste följa denna utveckling för att vara konkurrenskraftig på IT-marknaden. Implementeringar av Service Oriented Architecture, förkortat SOA, har i många fall visat sig vara lönsamma investeringar till en modernare arkitektur. Denna rapport förklarar på vilka sätt SOA kan vara kostnadseffektivt för verksamheter, samt identifierar kritiska framgångsfaktorer som är avgörande vid systemskiften till SOA. I kombination av en teoretisk litteraturstudie, analys av publicerade företagsfall och empirisk undersökning visar sig SOA-baserade lösningar vara kostnadseffektiva genom sänkta kostnader, tidsbesparingar och snabbare produktutveckling. Studien identifierar huvudsakligen fem kritiska framgångsfaktorer som är direkt kopplade till hur pass kostnadseffektiv en implementering av SOA kan komma att bli..

Systemarkitektur för presentation av geografiskinformation- Utredning av Informationssystem och produkter

Banverket Trafik has a responsibility to make sure that the companies who traffic the Swedish railroad have the correct information about the status of the railroad. One of Banverket Trafiks information systems (Opera) presents the train?s actual position on a map and provides the user with physical information about the trains. Due to increasing demands on the information systems, Banverket Trafik needs to update the present system architecture in order to manage the increasing demands on map graphics and map functions. This paper analysis the information system Opera on the basis of theory and support of methods and discuss problems and demands for Opera.

Analys och utveckling avverifieringsenhet för säker kontakteringvid kalibrering av RRUS.

This report presents a master thesis project performed at Elekta AB during the fall of 2013 and early 2014. Elekta is a medical technology company and their main product in the Stockholm office is a gamma knife used for radiosurgery. The gamma knife contains a cluster of a dozen motor servos and motors used for adjusting the patient and the radiation sources over a CAN bus. A self-developed hardware-in-loop simulator running on a PC with LabVIEW is currently being used for integration level testing of the control system of the gamma knife. The simulator has some problems with it not running in real-time and having other performance issues.

Hastighets- och positionsinterface för motorer

The environmental requirements and laws on combustion engine emissions are very tough today andthey will become even more stringent in the future. To achieve these requirements there are highdemands on the control systems for these engines. An improved precision in the measurement of anengine's speed and position gives the electronic control system an even better timing when it comes tofuel injection and ignition. This makes the engine more fuel efficient, reducing the emissions. This thesisis part of a collaborative project between Hoerbiger Control Systems and subsidiaries.

Nytta med NATO architecture framework ur ett förbandsperspektiv!?

Sedan ett antal år håller Försvarsmakten på att utveckla Försvarsmaktens Arkitektur och Försvarsmaktens Arkitekturramverk. Försvarsmaktens Arkitekturramverk skall vara ett stöd och styrning för Förvarsmaktens förändring och vidareutveckling, både nationellt och internationellt, samt spegla version 3 av NATO Architecture Framework. Ett försvarssystem vilket är utvecklat och används vid internationella insatser idag är Internationella Korvettstyrkan.Oförståelse för när, var och hur ett arkitekturramverk skall användas går att identifiera inom Försvarsmakten. Ett sätt, för att bringa förståelse för vad ett arkitekturramverk innebär, är att studera dess nytta. Denna uppsats har till syfte att visa på eventuell nytta med NATO Architecture Framework utifrån Internationella Korvettstyrkan.

Generationsskräpsamling med explicit kontroll av hårdvarucache

This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory..

Boendemiljo? i nationens skyltfo?nster : Internationell orientering i Svenska institutets material om stadsbyggnad 1945-1976

This thesis scrutinises the material on post World War II Swedish architecture produced by the Swedish Public diplomacy organisation "Svenska institutet" ("The Swedish Institute") during the period of 1945 through 1976. The outset is the dilemma encountered by every such organisation: how can the projected narrative of the own nation relate to as many countries as possible, without becoming too general? And how can the organisation address specific countries, without excluding others?By employing a two-sided model of interpreting the material, where it on the one hand is interpreted from the universal properties projected on the narrated architecture, and on the other hand from the particular ideological notions related to the same, the thesis suggests that the Swedish Institute continously relates the architecture to a West-European and American context by consistently connecting its universal properties to particular ideological notions orientated towards the West.The results underline the malleability in regard to ideological notions connected to modernist architecture. Earlier research in the Swedish context has focussed on how modernist architecture in Sweden, under the local tag "funktionalism", was established in regard to a Swedish audience as a particular Swedish architecture by relating it to a alleged continuos Swedish tradition, as well as to notions of a a progressive welfare state. By studying a similar material, though aimed towards a foreign audience, the thesis suggests that these allegations constitue an elucidatory example of how national and ideological narratives can form within the framework of technological-ideological dynamics of modernist architecture.

Posthuset blir hotell En studie av Centralposthuset i Göteborg och dess omvandling

This essay in Art History treats the former Central Post Office in Gothenburg, Sweden, and its recent transformation into a luxury hotel. The magnificent original building in neo-classical style, inaugurated in 1925, has been supplemented by a twelve stories high tower in postmodern style containing hotel rooms and suites, creating a complex architecture. The approach of this essay is that of ?lived architecture?, that is, how people experience and act in relation to the building. It is argued that the history of the building is rewritten in the marketing of the hotel and the management?s concept of creating a comfortable ?mini-world?for its guests.

Layers of land : the palimpsest concept in relation to landscape architecture

This paper researches how the palimpsest concept is used in relation to landscape, and how it can function as a tool within landscape architecture. Palimpsest originally refers to old parchment handwritings, where new text has been applied on top of effaced, but still discernable, earlier writing. Superimposition of information is the core of the palimpsest concept, used within a range of scientific as well as cultural fields. The purpose of this paper is to find how a landscape palimpsest can be distinguished among the many different layers of landscape, such as historical or cultural, and to examine the potential use of the concept in theory and practice of the landscape architecture field. The study is conducted as a literature survey, examining the use of the palimpsest concept within academic works related to landscape.

Se men inte röra - problemet med den performativa besökaren

Cloud computing is a new buzzword within the IT-industry, and introduces a whole new way of working with IT. The technique delivers web based services, which results in that the user no longer needs to install an application locally on a computer. Since the application no longer needs to run on a local entity, but in a datacenter located on a service provider, the users no longer need any specific hardware more than a computer with an internet connection. Cloud computing also offers IT-infrastructure and development environments as services, these three service types is better known as cloud services. Through the usage of different types of cloud services, the need for maintenance and hardware is significantly reduced.

Ystad Sandskog : En socialhistorisk analys av den privata rekreationsarkitekturens utveckling, mellan 1850 och 1940

This thesis is a case study that analyses the seaside resort Ystad Sandskog and its private architecture between 1850 and 1940. The multitude is evident in the area's architecture. The architectural development is analysed with the use of a social historical perspective, including class and hegemony. Regional as well as national affective factors are used in the analysis. Aside from the social aspects, architectural ideological developments, general development of the seaside resort and the area's committee with its prescriptions are all factors considered.By dividing the development in four different chronological phases, which all represents a certain architectural expression exemplified by a selection of buildings and the social class that it accompanies, a culmination in the architectural structural development of Sandskogen is shown.
