Syftet men denna studie är att förklara om tidskonsumtion som uttryck för Conspicuous Consumption kan påverkas av en människas personlighet utifrån The Big Five”. Studien baseras på en kvantitativ forskningsmetod samt en enkätundersökning genom ett bekvämlighetsurval som genererade 478 svar. Insamlade data analyserades i statistikprogrammet Jamovi. Resultatet visar att hypotes 1, 3 och 4 korroboreras medan 2 och 5 falsifieras. Utöver hypoteserna framkom det att neuroticism är positivt relaterat till tidskonsumtion samt att personer med höga poäng på openness inte lägger någon vikt vid en upptagen eller ledig livsstil eftersom båda anses generera status. Slutsatsen visar att trots att lyxkonsumtion och tidskonsumtion båda genererar status och är en del av Conspicuous Consumption styrs utövandet inte av samma personlighetsdrag. Studiens teoretiska bidrag syftar till att komplettera den begränsade forskningen angående Conspicuous Consumption och tidskonsumtion. Studiens praktiska bidrag har som syfte att öka personers medvetenhet kring hur de konsumerar sin tid samt vad de konsumerar sin tid på eftersom tidskonsumtion kan leda till negativa konsekvenser. Vidare forskning bör undersöka om samtliga personlighetsdrag är positivt relaterade till tidskonsumtion. Det vore även intressant att se om en mer detaljerad The Big Five-undersökning resulterar i starkare kopplingar till tidskonsumtion. / The purpose is to explain whether time consumption as an expression Conspicuous Consumption can be affected by a human ́s personality based on The Big Five. This study is based on a quantitative research method and a online survey based by a convenience samplet that generated 478 responses. Collected data were analyzed in the statistical program Jamovi. The results show that hypotheses 1, 3 and 4 are corroborated while 2 and 5 are falsified. In addition to the hypotheses, it was found that neuroticism is positively related to time consumption and that people with high scores on openness doesn ́t care if it ́s a busy or a free lifestyle because both are considered to generate status. Although luxury consumption and time consumption both generate status and are within Conspicuous Consumption, the use is not determined by the same personality traits. The theoretical contribution of the study aims to supplement the limited research on Conspicuous Consumption and time consumption. The purpose of the study's practical contribution is to increase people's awareness of how they consume their time and what they consume their time on as time consumption can lead to negative consequences. Further research should investigate whether all personality traits are positively related to time consumption. It would also be interesting to see if a more detailed The Big Five survey results in stronger links to time consumption.

This thesis deals with the analysis of data obtained by observing and measuring workplaces of assembly lines with a focus on the efficiency of their utilization, through selected elements of industrial engineering, which the reader can get acquainted with in the theoretical part of the thesis. In this thesis the line productivity during the shifts is analyzed, an ideal line balancing condition is defined and suggestion for changing the time of line consumption norm according to the measured line cycle time is made. According to the complex analyzes of the workplaces, suggestions are concluded and an economic appreciation of these proposals is also elaborated. The author of this thesis finds the main benefit of this work in increasing of the productivity of the analyzed line in the case of implementation of solution designs.

This work focuses on cryptographic protocol with privacy protection. The work solves the question of the elliptic curves and use in cryptography in conjunction with authentication protocols. The outputs of the work are two applications. The first application serves as a user and will replace the ID card. The second application is authentication and serves as a user authentication terminal. Both applications are designed for the Android operating system. Applications are used to select user attributes, confirm registration, user verification and show the result of verification.

This master’s thesis focuses on analysis of time consumption of machining process, the basic units of operating costs of production,optimization and subsequen tapplication to specific part. It is a turning shaft in two operations, named roughing and finishing turning. The aim is to find the optimum combination of life time of cutting tool and cutting speed, which is the main criterion for optimization in terms of minimum production cost or a maximum of productivity.

Ramavtal för förskolebyggnader togs fram 2018 av Sveriges Kommuner och Regioner, förkortat SKR, samt Adda. Ramavtalet innebär en alternativ metod till skräddarsytt byggande av förskolor och arbetet har syftat till att undersöka om några tids- och kostnadsbesparingar kan erhållas genom att använda avtalet. För att besvara frågeställningarna har information framför allt samlats in genom enkäter och intervjuer med sakkunniga inom området. De slutsatser som kan dras är att både tids- och kostnadsbesparingar kan uppstå genom att bygga förskolor med ramavtalet från SKR och Adda. Det konstateras att den tid som passerar från idé och vision av en ny förskola fram till att ett slutbesked utfärdas kan förkortas genom att använda ramavtalet vilket innebär att det är mer tidseffektivt än skräddarsytt byggande. Arbetet visar även att kostnadsbesparingar kan ske genom ramavtalet vilket visas genom att bland annat projektkostnad per förskoleplats och BTA i genomsnitt är lägre för dessa byggnader. Däremot anses de tidsbesparingar som uppstår vara mer markanta än de minskade kostnaderna. Slutsatserna är beroende på inlämnad data som utgör enbart en mindre del av det svenska förskolebeståndet och representerar därför inte hela beståndet. / Framework agreements for preschool buildings were presented in 2018 by the Swedish Association of Local Authorities and Regions, abbreviated as SKR, and Adda. The framework agreement represents an alternative method to customized construction of preschools and the work has aimed to investigate whether any time and cost savings can be obtained by using the framework agreement. In order to answer the questions, information has primarily been collected through surveys and interviews with experts in the field. The conclusions that can be stated are that both time and cost savings can occur by building preschools with framework agreement from SKR and Adda. It is found that the time that passes from the idea and vision of a new preschool until the building is finished can be shortened by using the framework agreement, which means that it is more time-efficient than customized construction. The work also shows that cost savings can be achieved through the framework agreement, which is shown by for example the project cost per childcare places and gross area being lower on average for these buildings. However, the time savings that occur are considered to be more significant than the reduced costs. The conclusions depend on submitted data that represents only a small portion of Swedish school buildings and therefore do not represent the entire building stock.
