Generators, or expressions capable of producing a sequence of results during evaluation, are found in one form or another in a number of programming languages. The use of generators has been limited by a lack of understanding of their operation. Control structures for generating expressions are usually patterned after the control structures found in conventional language designs. A notation for describing the static aspects of generators is presented in this dissertation. This notation is used to describe the operation of the generator-based control structures in Icon and to introduce several novel control structures based upon generator evaluation. Co-expressions are introduced as the expression-level equivalent of coroutines, and combined with generators to provide a powerful programming facility. Finally, machine and language independent models for implementation of goal-directed evaluation and co-expressions are presented.

The purpose of this report is to analyze the advantages of using programme software to monitor masshauling instead of using the conventional method. A comparsion between different programs will also be conducted in an attempt to determine the most affordable. This report is written for NCC Construction AB to help them choose a software most fitting for future projects.The report is based upon literature such as information taken from the developers website, existing reports with similar context, interviews with sellers of the software and interviews with people working in the building sector.The result of this report shows that there are several advantages with investing in a software that helps the management of a project and that it is something that should be taken under consideration instead of the existing method. Topcon is a clear favorite following the inquiries comparisons as done, when they deliver a complete system and not only a supplement to the current approach. Scanlaser are just in the beginning of its development, and is so far only out with an early version of the software, while Topcon has been brought further in development and therefore has more features in the program. To utilize Topcon we fully recommend that the device HT-30 is used.

The evidential quality of photographs has grown out of their early uses in tourism, colonialism, social control and media, and their often unconscious perception makes them not only susceptible to manipulation but also gives them the power to impart messages beyond those consciously considered by the viewer. This thesis explores seemingly innocuous photographs of the 2003 war in Iraq from the BBC and The New York Times online as published evidence that moves beyond simple coverage of the war by using subtle visual cues that speak to historically rooted power relationships between the Western ‘self’ and the Muslim ‘other’. Further, using Baudrillard’s understanding of simulation and dissimulation as a guide, this thesis introduces the notion of iconification and reveals how these images portrayed consistent themes thereby rendering the photographs icons for abstract concepts such as terrorism, oppression, and liberation. / Graduate

There has been much philosophical debate about whether the meaning of pictures can be analysed using theoretical frameworks normally employed within philosophy of language. A specific question within this debate is the question of whether pictures can express propositions. Instead of addressing this question in of pictures in a broad sense, this essay focuses on a specific category of pictures referred to as pictorial signs. These signs constitute a pictorial form of communication that we use in our everyday lives. The question of whether pictorial signs can express propositions should, because of this communicative use, be more approachable than the same question applied to pictures in general. While a standard approach to the question has been to investigate the extent to which pictures may share some syntactic or semantic features with natural language, the approach in this essay is instead to look at how pictorial signs are used. The suggested strategy is to approach the question of propositionality by attempting to translate a particular sign into some sentence in natural language on the basis of how the sign is used, rather than analysing its structure.

Introduktion: Fallolyckor bland äldre orsakar stora samhällskostnader och bidrar även till stort lidande i det vardagliga livet. Bortsett från fysiska skador så är fallrädsla även ett stort folkhälsoproblem. Fallrädsla defineras som en upplevd frånvaro av trygghet för att hålla balans vid aktiviteter, som resulterar till en mängd olika hälsoproblem. Vanligtvis används Fall Efficacy Scale - International (FES-I) och Activities-specific Balance Confidence Scale (ABC-scale) som bedömningsinstrument för självskattning av fallrädsla. Däremot så saknas utvärdering av fallrädsla utifrån ett funktionellt perspektiv. Late-Life Function and Disability Instrument (LLFDI) är ett självskattningsformulär som ursprungligen utformats för bruk vid intervjuer för äldre 60 år och uppåt.Syfte: Syftet med denna studie var att undersöka om det finns ett samband mellan självskattad funktionsnivå enligt LLFDI samt självskattad fallrädsla enligt Iconographical - Falls Efficacy Scale (Icon-FES) och ABC scale bland äldre personer över 70 år. Delsyftet var att undersöka korrelationen bland de tre domänerna i LLFDI för att se vilka nedsättningar som korrelerar bäst med fallrädsla. Metod: Sambandet mellan skattad funktion enligt LLFDI samt upplevd fallrädsla enligt ABS-scale och Icon-FES undersöktes med Spearmans Rho i ett datamaterial med 67 deltagare över 70 år som deltagit i en tidigare studie av fallpreventiv träning. Resultat: En hög statistisk signifikant korrelation enligt Hinkel hittades mellan de funktionella domänerna hos LLFDI och ABC-scale (FU och GNE) och Icon-FES (FU och ANE). Måttliga korrelationer observerades även mellan LLFDI och ABC-scale (ANE) och Icon-FES (GNE). Enbart en domän övre extremitet visade väldigt låg korrelation med fallrädsla.  Slutsats: Eftersom hög korrelation kundes ses bidrar resultat stärker det sambandet mellan självskattad funktion och fallrädsla bland äldre som bor i en hemmiljö. Framtida studier bör undersöka resultatet bland ett könsuppdelat stickprov i form av en tvärsnittsstudie för att mäta prevalens av fallrädsla samt exponering av fysisk inaktivitet os deltagarna.

This essay is an effort to write my thoughts and reflections on my art practice, focusing on the work to-be-realized for my solo show in March 2021 at Galleri Mejan in Stockholm. I’ve had the intention to complement and stabilize my imagined-artwork with my writing, only to realize such a task’s difficulty. Firstly, because language itself can be unstable. Secondly, fear of losing a quality in art that is unstable in its nature. The essay consists of three sections: In the first one, I tell how I think and feel through my art practice. I also propose making space for new knowledge: In my art practice, I lean on magical thinking to stimulate bodily movements.1 I think that we need to balance ourselves between rational thinking and other modes of thinking, and this in-between-space requires continuous negotiations of different kinds. In section two, I explain how I think of images and share how I process them through my work. Then I share stories of entangled images that I’m using as source images in my current work. In the third and last section, I delve into my deep desire to control images. I challenge told narratives and reflect on creative practices of destruction and reparation. / @ Galleri Mejan, Exercisplan 3, March 2021 Media: installation and a video projection. Materials: Clay, ceramic, plaster, linen, and mixed media.   The Making and Breaking of an Icon is a long-term project: I repeatedly destroy and repair a self-made ceramic sculpture. The faceless figure has multiple arms and hands that seem to be hugging or containing the body. At the moment of showing the work at Galleri Mejan, the sculpture was broken, and in process of reparation. Fragments of the sculpture were laying on the ground, I continued to glue them up during the show. A shelf placed up high in the same room displays 7 small plaster replicas of the same figure, but with the addition of a horned cap on their heads. one of the replicas is broken on the ground underneath the shelf. The mold reproducing the plaster pieces is shown by the corner and seems to be in the action of production.  By the entrance, a fetus-like ceramic sculpture is opening both arms. In the other room, the video work "Falling for the Narrative" is showing a performance I did earlier with the sculpture. In this performance, dressed in a self-made costume, I interact with the sculpture as a living thing: I project veneration and aggression on it. The costume that is made of linen, has carrier sacks sewed in the back, filled with rice and coins. the costume weighs around 4kgs. In the corner of the room, a pile of dust is formed on the ground.

This paper explores the implications of metaphorical elements in the contextof physical products that coexist with a digital interface, through an empiricand theoretical approach. Further, problematic aspects of the use ofmetaphors in a digital space will be discussed, and two prototypes will becreated to investigate how icons are perceived in different contexts.In cooperation with home-security company Verisure, the prototypes will beproduced and usability tested. Fundamental interaction design principleswill be implemented in order to investigate the impact of metaphor in iconbasedinteraction. These findings will be discussed and processed into a setof key factors to consider when working with icons.
