Useless things. I normally use trash things like pattern in painting still life. My father suffers from obsessive compulsive disorder – accumulation of things. In addition to painting, I also work with objects themselves. My interest also closely related to how the concepts of the subject, object and artifact are appliing in contemporary art. There are the tradition of imitation fact, principle of ready-made, the issue of technical reproducibility and virtual reality of things in history of art. As a central theme of my thesis, I selected the part of bodywork Tatra 613, which carries all the testimony about ,,useless and hopeless "situation in which it is located. It is also an object monumental and visually very aesthetic. Yet it is not my intention to settle for the principle of redy-made. Asked about artwork as intermediaries art and its seemingly useless producing and reproducing, I want to try to create another such usless situation. That's why I make a cardboard copy (1: 1) of this object. I also make video with motive 3D copy of the same object. I like to create some voltage between that useless object and valuable art practice. I think, it does not just mean such futility when these objects will be viewed as an art.

(AJ) Food contact materials pose a risk to human health due to a variety of contaminants which they can release into food. These compounds, migrants, include aromatic hydrocarbons, dialkyl phthalates, bisphenols, printing ink photoinitiators, and perfluoroalkyl compounds. The determination of all these substances can be expensive and time-consuming since universally applicable analytical approaches are not available nowadays. This work attempted to develop methods for the simultaneous determination of migrants from all of the mentioned groups in paper-based food contact materials and fatty food. A total of 68 contaminants were studied in paper products using liquid chromatography and gas chromatography coupled with tandem mass spectrometry detection. All analytes were isolated simultaneously using the modified "QuEChERS" method. This method demonstrated acceptable recovery and repeatability for most analytes in the validation study; LOQs ranged from 1.3 to 220 µg/kg. Analysis of 132 real paper products confirmed the occurrence of almost all studied analytes, which were often present in complex mixtures and at concentrations up to 628 mg/kg. A total of 41 potential contaminants were monitored in fatty foods by liquid chromatography with tandem mass detection. Contamination of the mobile phase by...

This project is an examination of the possibility of using existing software to develop Virtual Reality (VR) software that includes key aspects of objects in a user’s surroundings into a virtual environment, producing Augmented Virtuality (AV). A defining limitation is the requirement that the software be consumer-accessible, meaning it needs run on a common smartphone with no additional equipment. Two related AV concepts were considered: shape reconstruction and positional tracking. Two categories of techniques were considered for taking the measurements of reality necessary to achieve those AV concepts using only a monocular RGB camera as sensor: monocular visual SLAM (mvSLAM) and Structure from Motion (SfM). Two lists of requirements were constructed, formalising the notions of AV and consumer-accessibility. A search process was then conducted, where existing software packages were evaluated for their suitability to be included in a piece of software fulfilling all requirements. The evaluations of SfM systems were made in combination with Multi-View Stereo (MVS) systems – a necessary complement for achieving visible shape reconstruction using a system that outputs point clouds. After thoroughly evaluating a variety of software, it was concluded that consumer-accessible AV can not currently be achieved by combining existing packages, due to several issues. While future hardware performance increases and new software implementations would solve complexity and availability issues, some inaccuracy and usability issues are inherent to the limitation of using a monocular camera. / Detta projekt är en undersökning av möjligheten att använda befintlig programvara till att utveckla Virtual Reality (VR)-programvara som infogar framstående aspekter av objekt från en användares omgivning in i en virtuell miljö och därmed skapar Augmented Virtuality (AV). En definierande begränsning är kravet på att programvaran skall vara konsumenttillgänglig, vilket innebär att den behöver kunna köras på en vanlig smartphone utan extra utrustning. Två besläktade AV-koncept beaktades: formrekonstruktion och positionsspårning. Två kategorier av tekniker togs i beaktande, vilka kunde användas för att göra de uppmätningar av verkligheten som var nödvändiga för att uppnå de tänkta AV-koncepten med hjälp av endast en monokulär RGB-kamera som sensor: monocular visual SLAM (mvSLAM) och Structure from Motion (SfM). Två listor med kriterier konstruerades, vilka formaliserade begreppen AV och konsumenttillgänglighet. En sökprocess utfördes sedan, där befintliga programvarupaket utvärderades för sin lämplighet att inkluderas i en programvara som uppfyllde alla kriterier. Utvärderingarna av SfM-system gjordes i kombination med Multi-View Stereo (MVS)-system – ett nödvändigt komplement för att uppnå synlig formrekonstruktion med ett system vars utdata är punktmoln. Efter att noggrant ha utvärderat en mängd programvara var slutsatsen att konsumenttillgänglig AV inte för närvarande kan uppnås genom att kombinera befintliga programvarupaket, på grund av ett antal olika problem. Medan framtida prestandaökningar hos maskinvara och nya programvarutillämpningar skulle lösa problem med komplexitet och tillgänglighet, är vissa problem med tillförlitlighet och användbarhet inneboende hos begränsningen till att använda en monokulär kamera.

[EN] Packaging is a permanent presence and takes a significant expression in daily life, it contains, protects, informs and gives character to the products, establishing an inseparable relationship between content and container. This research focused on formal, material and communicative packaging aspects of liquid food products, performs a mapping of the issues related to the interrelation of practical functions (performance for the user), aesthetic (configuration and interaction with the user) and symbolic (significance to the user) from the liquid food packages, having as confluence point the relationship content/ product container in the set of interactions/ user/ environment. Seen as an interface between the product and the user, the packaging of liquid food products, occupies an essential place in our society, allowing an uncountable number of products to reach the hands of those who need them, intact and in perfect condition. The package preserves the physical and temporal natural products, covering them and giving them shape, becoming a product skin like the skin of the fruit or human skin, prolonging their existence, with direct health benefits and well being of the populations. This thesis has as study object the packaging of liquid food products and how its shape expresses its identity, the concept and function of the product it contains and conforms. This research resorted to analytical studies, based on the reflections of Flusser and Lipovetsky, around the man and his relationship to the object and conducted the identification and recognition of archetypal packaging in the universe of reference products (milk, juice, water and hybrid drinks), as well as the morphological and qualitative comparative analysis of liquid food packaging in different materials (glass, multilayer cardboard, metal, plastic), having as a study focus the inseparable relationship between the content and the container. This study resulted in the achievement of Tetra Con)forma project goal so that provided the constructive possibilities of the multilayer material for forming a packagings for hybrid liquid drinks, emphasizing the concepts of nomadism (portability), customization (composition) and theatricality (convertibility), wherein the shape is expressed by the structural dimension portability, in the communicative by the composition and in the symbolic by convertibility. / [ES] El envase es una presencia permanente y asume una expresión significativa en lo cotidiano, al contener, proteger, informar y conferir carácter a los productos estableciendo una relación indisociable entre el contenido y el contenedor. Esta investigación centrada en los aspectos formales, materiales y comunicativos de los envases de productos alimenticios líquidos, efectúa un mapeado de las cuestiones relacionadas con la interrelación de las funciones prácticas (desempeño para el usuario), estéticas (configuración e interacción con el usuario) y simbólicas (significado para el usuario) de los envases de productos líquidos alimenticios teniendo como punto de convergencia la relación contenido/ contenedor en el conjunto de las interacciones producto/ usuario/ medio. Concebida como interfaz entre el producto y el usuario, el envase de productos líquidos alimentícios ocupa un lugar esencial en nuestra sociedad, permitiendo que un sin número de productos llegue a manos de aquellos que los necesitan, intactos y perfectas condiciones de uso. El envase preserva la integridad física y temporal de los productos naturales, recubriéndolos y dándoles forma, transformándose en una piel del producto a semejanza de la piel de la fruta o de la piel humana, prolongando su existencia, con beneficios directos para la salud y bienestar de la población. La presente tesis tiene por objeto de estudio el envase de productos líquidos alimentícios y el modo en el que su forma expresa la identidad, el concepto y la función del producto que contiene y conforma. Esta investigación provino de estudios analíticos, fundamentados en las reflexiones de Flusser y Lipovetsky en torno al hombre y a su relación con el objeto y procedió a la identificación y reconocimiento de envases arquetipo en el universo de productos de referencia (leche, zumos, agua y bebidas híbridas), así como el análisis morfológico comparado y cualitativo de los envases de productos líquidos alimentícios en los diferentes materiales (vidrio, cartón multicapa, metal, plástico), teniendo como foco de estudio la relación indisociable entre el contenido y el contenedor. Este estudio culminó con la realización del meta proyecto Tetra Con)forma, que previó las posibilidades constructivas del material multicapa para conformar un volumen con)formador para bebidas líquidas híbridas, enfatizando los conceptos de nomadismo (portabilidad), personalización (composición) y teatralidad (convertibilidad), en que se expresa la forma en la dimensión estructural por la portabilidad, en la comunicativa por la composición y en la simbólica por la convertibilidad. / [CA] L'envàs és una presència permanent i assumeix una expressió significativa el quotidià, en contenir, protegir, informar i conferir caràcter als productes establint una relació indissociable entre el contingut i el contenidor. Aquesta recerca centrada en els aspectes formals, materials i comunicatius dels envasos de productes alimentosos líquids, efectua una localització de les qüestions relacionades amb la correspondència de les funcions pràctiques (acompliment per a l'usuari), estètiques (configuració i interacció amb l'usuari) i simbòliques (significat per a l'usuari) dels envasos de productes líquids alimentosos tenint com a punt de convergència la relació contingut/ contenidor en el conjunt de les interacciones producte/ usuari/ mitjà. Concebuda com a interfície entre el producte i l'usuari, l'envàs de productes líquids alimentosos ocupa un lloc essencial en la nostra societat, permetent que un sense nombre de productes arriben a les mans d'aquells que els necessiten, intactes i perfectes condicions d'ús. L'envàs preserva la integritat física i temporal dels productes naturals, recobrint-los i donant-los forma, transformant-se en una pell del producte a semblança de la pell de la fruita o de la pell humana, perllongant la seua existència, amb beneficis directes per a la salut i benestar de la població. La present tesi té per objecte d'estudi l'envàs de productes líquids alimentosos i la manera en el qual la seua forma expressa la identitat, el concepte i la funció del producte que conté i conforma.

To what extent can virtual reality be used to induce real-life tourism? This question becomes even more relevant in these covid-19 times. However, research on virtual reality concerning tourism has not engaged substantively with this question yet and thus this study seeks to address this question. This thesis is an explorative case study of the development of the prototype of a place-based virtual reality experience of Mariebergsskogen in Karlstad, Sweden. The purpose of this study is to investigate and show how a place-based virtual reality experience can add value to the experience and promotion of Mariebergsskogen. This thesis goes beyond ocularcentrism highlighting the involvement of senses, the whole body and emotions in experiencing a destination. How can a deeper emotional connection to a destination be evoked through virtual reality revealing the characteristics, uniqueness and rootedness of the place? A geomedia approach is taken that combines a sensitivity to place with media to arrive at a multi-dimensional view of Mariebergsskogen considering place representations, engagements and its roots to history. Place is conceptualized by recourse to Lefebvre’s (2011) spatial triad: lived, perceived and imagined that are in a dialectic relationship. The methodological model created has been informed by the project on place-based digital experiences (PDU) at the University of Karlstad in Sweden. Tourists are considered active agents in creating tourism destinations and this study emphasizes their engagement as co-creators in the prototype development process. A methodological model is proposed that combines a place analysis with workshops consisting of a user study and a co-creation workshop supplemented with insights from interviews with virtual reality developers and stakeholders from Region Värmland and Karlstad Municipality.
