[pt] O presente trabalho tem por objetivo compreender as representações sociais das mulheres denominadas periguetes. Articulando o debate sobre gênero, mídia e sujeitos desviantes, pretende-se refletir sobre o papel das periguetes na cultura contemporânea. Além disso, discutem-se questões relacionadas aos estudos sobre o corpo, aqui tomado como capital social. As mulheres periguetes são analisadas por suas características e representações, o que nos leva à reflexão sobre um possível modelo típico ideal de beleza feminino. Seja por suas atitudes, postura, gestual ou vestimenta, tais mulheres são ao mesmo tempo reconhecidas, mas também discriminadas. A metodologia adotada consistiu em revisão bibliográfica, contando com o aporte teórico de autores das Ciências Sociais, como Erving Goffman, Howard Becker, Mary Douglas, Mirian Goldenberg e Simone de Beauvoir, entre outros. Além disso, foi realizada uma análise das representações sociais das periguetes presentes na mídia, através de duas personagens de telenovelas, e também na dinâmica das interações sociais presentes no discurso do senso comum, através de Entrevistas em Profundidade. Para tanto, foram ouvidos 24 jovens, homens e mulheres, de 20 a 29 anos, moradores da Baixada Fluminense e Zona Sul do Rio de Janeiro. / [en] The present work aims at understanding the social representations of women so-called periguetes. Managing debates on gender, media and deviant individuals, this study seeks to reflect about the role of periguetes within contemporary culture. Furthermore, questions related to body studies, herein taken as social capital, are also discussed. The periguete women are analysed based on their features and representations, which leads us to reflect over an ideal typical model of feminine beauty. Be it based on attitudes, behaviour, gestures or clothing, such women are at once recognised, but also discriminated against. The methodology chosen consisted of literature review in light of theoretical studies from Social Science authors as Erving Goffman, Howard Becker, Mary Douglas, Mirian Goldenberg and Simone Beauvoir, among others. Besides, it was conducted an analysis of periguetes social representations pictured in the media through soap operas characters, and also an analysis on the dynamic of social interactions within common sense speech, through Depth Interviews . To do so, it was heard 24 young adults, male and female, aged 20-29 years-old, residents of Baixada Fluminense and Rio de Janeiro s South Zone.

Sexmissbruk eller diagnosmissbruk? – En diskursanalys av begreppet sexmissbruk Jakobsson, R.Key words: diagnoses, hypersexuality, medicalization, nymphomania, sexual addiction, sexual behavior, sexual compulsivity, sexual deviation, shame, social construction.Background: Sexual addiction has been given a dominant discoursive power in Sweden which (re)inforces the idea that sexuality is essentially a dangerous and lethal force.Methods: The thesis consists of two sub studies. Firstly, a critical discourse analysis is conducted over scientifical articles of sexual addiction and sexual compulsivity. Secondly, a critical discourse analysis of the concept of sexual addiction in newspapers in Sweden’s largest newspaper, DN, and an evening paper, Aftonbladet. These two sub studies are reflected towards each other to examine the construction and discourses surrounding sexual addiction.Results: The first sub study shows that sexual addiction is a term and concept that lacks empirical data. However, research still speculates that a sex addict can be someone who compulsively consumes any sexual behaviors that deviates from marital sex. The second sub study shows that sexual addiction is a vague concept that could be applied to most people in society; it may include people who masturbate, are unfaithfull, are rapists, perform incest, consume pornography, have difficulties with intimacy and/or have multiple sexual partners.Conclusion: Sexual addiction is a moral concept, which pathologizes people who deviate from erotic normalcy. The media articles presented a vague image of a sex addict that includes a series of sexual behaviors, ranging from masturbation to sex offending. Although research has been conducted for over 30 years, there is no empirical data about what constitutes sexual addiction and what the potential consequences for the individual and society are. In sum, both science and popular discourses presents a potential addiction to diagnoses.Suggested Citation: "Jakobsson. R.

Mobila hydrauliska ventiler används ofta i tunga industrier för att styra hydrauliska system för att hantera material. Funktionaliteten är kritisk i dessa situationer då det utgör en miljöfara och säkerhetsfara om funktionaliteten inte är uppnådd. För att säkerställa funktionaliteten kvalitetskontrollerar Nordhydraulic samtliga ventiler i en testbänk innan de skickas till kund. Läckage och manöverkraft är några av de parametrar som testas. Om en ventil inte blir godkänd omarbetas ventilen för att sedan testas om igen. Detta medför interna kvalitetsbristkostnader för Nordhydraulic. Examensarbetet syftade till att reducera ventilavvikelser vid slutprovning genom att identifiera vilka rotorsaker som bidragit till avvikelserna, utforma ett visuellt sätt att övervaka ventilavvikelserna samt att ge rekommendationer till förbättringsåtgärder för att reducera dessa. Examensarbete genomfördes med hjälp av Andersen och Fagerhaugs (2014) föreslagna metod för rotorsaksanalys. Resultatet av examensarbetet visade att slidtillverkningsprocessen, bristfällig dokumentation av data och arbetsinstruktioner var rotorsaker som har bidragit till ventilavvikelserna vid slutprovning. Enligt operatörerna var slidbyte den mest frekventa åtgärden när en ventil inte blir godkänd. Sliderna kvalitetskontrolleras under tillverkningen, men dokumenteras inte. Variationen i slidernas tillverkningsprocess kan därför inte kvantifieras eller uppskattas på ett tillfredsställande sätt, vilket innebar att det var svårt att bedöma huruvida sliderna tillverkas inom de uppsatta toleranserna. Resultatet visade även på utmaningar med dokumentationen av provdatan i enlighet med de specificerade instruktionerna. Detta betonar vikten av förstärkta dokumentationsrutiner för att säkerställa fullständighet i provdatabasen och därigenom förbättra övervakningen av ventiltesterna. Nordhydraulic rekommenderas att utöka sin statistiska processtyrning för slidtillverkningen med hjälp av ett ramverk som examensarbetet har tagit fram. Genom att definiera huruvida slidtillverkningsprocessen är stabil och duglig kan förbättringsarbeten utföras. Examensarbetet har också utformat en dashboard som Nordhydraulic kan använda för att övervaka slutprovningen visuellt och upptäcka anomalier vid slutprovningen. Sammanfattningsvis fokuserar examensarbetet på att reducera avvikelserna hos ventiler vid slutprovning för Nordhydraulic. De identifierade rotorsakerna, tillsammans med det föreslagna ramverket och den visuella övervakningsmetoden, ger värdefulla insikter för Nordhydraulic att förbättra sina kvalitetskontrollprocesser, minimera avvikelser och säkerställa högkvalitativa ventiler till sina kunder. / Mobile hydraulic valves are frequently used in heavy industries for material handling, thanks to their high power-to-weight ratio. Functionality is critical in these scenarios as it poses both environmental and safety hazards if not achieved. To ensure functionality, Nordhydraulic performs quality inspections on all valves before they are shipped to customers, utilizing a test bench. Parameters such as leakage and actuation force are among those tested. If a valve fails to meet the requirements, it undergoes rework and is retested, resulting in internal failure costs for Nordhydraulic.  The objective of this thesis was to reduce valve deviations during final testing by identifying the root causes contributing to these deviations, designing a visual monitoring approach for valve deviations, and providing recommendations for improvement measures to reduce valve deviations. This thesis utilized the root cause analysis method proposed by Andersen and Fagerhaug (2014). The results of the thesis revealed that the spool manufacturing process, insufficient data documentation, and work instructions were identified as root causes contributing to valve deviations during final testing. According to the operators, replacing the spool was the most frequent corrective action when a valve failed to meet the requirements. The variation in the spool manufacturing process could not be quantified or estimated satisfactorily, making it difficult to assess whether the components were manufactured within the specified tolerances.  The results also indicated challenges with the documentation of test data in accordance with the specified instructions. This emphasizes the importance of strengthened documentation procedures to ensure completeness in the test database and thereby enhance the monitoring of valve tests. Nordhydraulic is recommended to increase their statistical process control using the framework developed in this thesis. By defining the stability and capability of the spool manufacturing process to produce within the specified tolerances, improvement efforts can be undertaken. The thesis has also designed a dashboard that Nordhydraulic can utilize to visually monitor the final testing process and detect anomalies. In conclusion, this thesis addresses the issue of reducing valve deviations during final testing for Nordhydraulic. The identified root causes, along with the proposed framework and visual monitoring approach, provide valuable insights for Nordhydraulic to enhance their quality control processes, minimize deviations, and ensure high-quality valves for their customers.

The security of multi-robot systems is critical in various applications such as patrol, transportation, and search and rescue operations, where they face threats from adversaries attempting to gain control of the robots. These compromised robots are significant threats as they allow attackers to steer robots towards forbidden areas without being detected, potentially causing harm or compromising the mission. To address this problem, we propose a resilient planning, task assignment, and control framework. The proposed framework builds a multi-robot plan where robots are designed to get close enough to other robots according to a co-observation schedule, in order to mutually check for abnormal behaviors. For the first part of the thesis, we propose an optimal trajectory solver based on the alternating direction method of multipliers (ADMM) to generate multi-agent trajectories that satisfy spatio-temporal requirements introduced by the co-observation schedules. As part of the formulation, we provide a new reachability constraint to guarantee that, despite adversarial movement by the attacker, a compromised robot cannot reach forbidden areas between co-observations without being detected. In the second part of the thesis, to further enhance the system's performance, reliability, and robustness, we propose to deploy multiple robots on each route to form sub-teams. A new cross-trajectory co-observation scheme between sub-teams is introduced that preserves the optimal unsecured trajectories. The new planner ensures that at least one robot in each sub-team sticks to the planned trajectories, while sub-teams can constantly exchange robots during the task introducing additional co-observations that can secure originally unsecured routes. We show that the planning of cross-trajectory co-observations can be transformed into a network flow problem and solved using traditional linear program technique. In the final part of the thesis, we show that the introduction of sub-teams also improves the multi-robot system's robustness to unplanned situations, allowing servicing unplanned online events without breaking the security requirements. This is achieved by a distributed task assignment algorithm based on consensus ADMM which can handle tasks with different priorities. The assignment result and security requirements are formulated as spatio-temporal schedules and guaranteed through control barrier function (CBF) based controls.

Instructions for a Walk Off Line engages in a reparative reading of Fluxus and Conceptual artworks, with a focus on the practice of stanley brouwn, to outline a set of strategies for contemporary artists to approach the role of bureaucracy in mediating their relationship with art institutions. This research starts from the observation that modern and contemporary art museums are increasingly invested in inviting underrepresented artists into their spaces without engaging in the necessary structural changes to meet their conditions for being included. Bureaucracy is one of those structural elements that maintains and perpetuates certain norms and excludes those who do not have proximity to them. In the approach to Fluxus and Conceptual works, this thesis relies on intermedia and queer theory to analyse how bureaucratic form, language, and function are appropriated and fused with artistic media to expose normative systems, destabilise them, and deviate from them. stanley brouwn’s Aantal stappen of meters in de richting van diverse steden in the collection of Van Abbemuseum Eindhoven is taken as an exemplary case, as brouwn is known to have a specific set of conditions for the display and dissemination of his work. Situating brouwn’s practice in relation to the strategies of appropriation, exposure, destabilisation and deviation, this research proposes his work and conditions as a relational practice of walking off line. The notion of the line, a recurring formal aspect in brouwn’s work, represents the norm that brouwn and his contemporaries deviate from. The museum staff and the audience are invited into this process through different instructions and conditions for the installation of, and engagement with the work. This thesis demonstrates that these instructions are not static but allow for interpretations and invite playfulness. The strategies in this research are offered in the same way; they are not presented as a single way of walking off line but invite a range of possibilities based on the needs and conditions relevant to the context of working with bureaucracy in the arts today.

Syftet med denna studie är att utreda hur ett stort byggföretag i norra Sverige hanterar eventuella fel som upptäcks på byggplatsen i produktionsskedet, och hur denna erfarenhetsåterföringsprocess kan effektiviseras. För att besvara studiens syfte ställdes följande frågeställningar upp:  Hur går en stor aktör i byggbranschen till väga när de upptäcker ett fel på byggplatsen som kräver en revidering av ritning/modell?  Hur kan en stor aktör i byggbranschen effektivisera sin erfarenhetsåterföringsprocess vid produktionsskedet för att förebygga att eventuella fel återkommer? Studien tar även upp tidigare forskning kring BIM, vad det är och hur det används, andra digitala hjälpmedel samt vad som innebär med erfarenhetsåterföring och ändrings-PM. Rapporten ger även en inblick i vad som menas med kvalitet och olika typer av kvalitetsarbete. För att besvara studiens frågeställningar och syfte så har en intervjustudie genomförts på ett stort byggföretag där samtliga respondenter har varit placerade på projekt som är geografiskt belägna i norra Sverige. I rapportens resultatdel presenteras en sammanställd version av intervjustudien som sedan diskuteras i studiens diskussionskapitel. Resultatet visar att företagets arbete med erfarenhetsåterföring kan förbättras samt att arbetsprocessen inte ser likadan ut på samtliga byggarbetsplatser. I rapportens diskussionsdel presenteras ett flertal förslag på åtgärder och förbättringar som kan nyttjas av företaget för att effektivisera sin erfarenhetsåterföringsprocess samt för att motverka att specifika fel återkommer. Ett utdrag av de lösningar som presenteras är att företaget kan arbeta mer med ständiga förbättringar, vara mer noggranna med uppföljningsmöten och slutmöten, tillämpa mer kontakt mellan projektansvariga samt utföra ett mer grundligt arbete med 3D-modellen. / The purpose of this study is to investigate how a big construction company in the north region of Sweden manage possible errors that occurs during the production, and how the process of experience transfer can improve. To answer the purpose of this study, the following research questions was asked:  How does a large perator in the construction sector, located in the north region of Sweden, act when an error is discovered and requires a revision of blueprint/model?  How can a large perator in the construction sector, located in the north region of Sweden, increase their experience transfer during the production to prevent recurring errors? The study also includes previous research regarding BIM, what it is and how it is used, other digital assistive technologies and what experience transfer and modification-PM means. The report also consists of an explanation of quality and different quality methods. To answer the studies research questions and purpose, an interview survey has been carried out on a big construction company where all of responders have been in projects in the specific region. In the result, a summary of the interview study is presented and discussed in the analyze and discussion part. The work with experience transfer in the company can be improved according to the result, it also shows that standard processes can be different between various workplaces. In the discussion part, a few possible actions and improvements are presented to help the company with transfer of experience and reoccurring errors. Long-term improvement work, more focus on follow-up meetings and final meetings, better contact between project managers and more thorough work on the 3D-model are a couple of suggestions from the writers.

This study aims to investigate the individual's experience of conscious consumption reduction in relation to society's consumption norms. By not focusing on motives or causes behind the change, but instead illustrating the subjective and social consequences, the study provides a deeper understanding of how the individual's self-perception and social relationships are affected. This will be studied based on the following questions “How does a conscious reduction in consumption affect the individual's self-perception and identity in relation to society's consumption norms?” and “What social and cultural effects do individuals experience when they reduce their consumption on purpose, and how does this affect relationships within the individual's immediate circle?” Previous research has been interested in understanding why individuals change their consumption behaviour. Social resistance from society and the surrounding community has also been a broad area of research. A significant focus has also been to study consumption patterns from a sustainability perspective, where research identifies challenges and how today's society can be treated. This study aims to contribute with an in-depth understanding of how conscious consumption reduction affects the individual's life aspects and relationships, which may have far-reaching implications for our understanding of society's changing consumption patterns. The theoretical framework of the study consists of Emilé Durkheim's social coercion consisting of the normative coercion, the cultural coercion, the material coercion and the structural coercion. In combination with this, Robert K. Merton's social tensions, taken from his strain theory, are also applied. The study is based on qualitative semi-structured interviews, where we study 8 individuals' perceived effects of consumption reductions. The results suggest that a reduction in consumption strengthens the individual's empowerment and promotes self-reflection. Through reduced emphasis on external factors, individuals shape their self-perception beyond materialism. Even though their consumption reduction violates norms, they are met with curiosity. These individuals appear to act as agents of normative change by raising awareness of the impact of consumption and promoting a transformation towards a more sustainable way of living. / Denna studie ämnar undersöka individens upplevelse av medveten konsumtionsminskning i förhållande till samhällets konsumtionsnormer. Genom att inte rikta in sig på motiv eller orsaker bakom förändringen, utan i stället åskådliggöra de subjektiva och sociala konsekvenserna, ger studien en djupare förståelse för hur individens självuppfattning och sociala relationer påverkas. Detta kommer studeras utifrån frågeställningarna ”Hur påverkar en medveten minskning av konsumtion individens självuppfattning och identitet i förhållande till samhällets konsumtionsnormer?” och “Vilka sociala och kulturella effekter upplever individer som minskar sin konsumtion med avsikt, och hur påverkar detta relationer inom individens närmaste krets?” Tidigare forskning har intresserat sig för att förstå varför individer ändrar sitt konsumtionsbeteende. Även det sociala motståndet från samhälle och omgivning har varit ett vida forskningsområde. Ett betydande fokus har även varit att studera konsumtionsmönster ur ett hållbarhetsperspektiv, där forskningen identifierar utmaningar och hur dagens samhälle. Denna studie avser bidra med en ingående förståelse för hur medveten konsumtionsminskning påverkar individens livsaspekter och relationer, vilket kan ha långtgående implikationer för vår förståelse av samhällets föränderliga konsumtionsmönster. Studiens teoretiska ramverk består av Emilé Durkheims sociala tvång bestående av det normativa tvånget, det kulturella tvånget, det materiella tvånget och det strukturella tvånget. I kombination med detta tillämpas även Robert K Mertons samhälleliga spänningar, taget från hans strainteori. Studien baseras på kvalitativa semistrukturerade intervjuer, där vi studerar 8 individers upplevda effekter av konsumtionsminskningar. Resultatet tyder på att en minskning av konsumtion stärker individens egenmakt och främjar självreflektion. Genom minskad betoning på yttre faktorer, formar individer sin självuppfattning bortom materialism. Trots att deras konsumtionsminskning bryter mot normer, möts de av nyfikenhet. Dessa individer tycks agera som agenter för normativ förändring genom att öka medvetenheten om konsumtionens påverkan och främjar en omvandling mot ett mer hållbart levnadssätt.

Hole deviation is one of the most significant problems in drilling applications. Deviated holes result in inefficient blasting and have severe economic impacts due to increased equipment consumption. Conversely, straighter holes help in increasing production scales and reduce operational costs. The reason for hole deviations could range from anisotropic behavior of the rocks being drilled to the behavior of the drill string under the action of imposed forces. Deviations caused due to rock anisotropy are complex in nature and non-controllable to some extent but deviations due to mechanics of drill strings can be controlled as they lie in the operator’s area of influence. In this thesis, a 2D mathematical model is constructed which predicts the bending behavior of the drill rod and the model is further extended to predict the buckled profile of the entire drill string. Two bit state parameters are defined which help in better characterization of hole deviation and understanding of deflected state of the drill bit. Epiroc’s drilling data is inserted in the model developed and the buckled profile of the drill string is studied. The developed model is used to further understand the effect of various drilling parameters like bit thrust, angle of inclination, hole length, etc. on hole deviation. Through the results it was concluded that the bending stiffness of the drill rods is the most critical parameter influencing hole deviation for Epiroc’s drilling data and drill string setup. Finally, potential improvements and techniques to validate results obtained from the mathematical model are proposed. / Hålavvikelse är ett av de mest avgörande problemen i borrapplikationer. Hålavvikelse resulterar i ineffektiv sprängning och får allvarliga ekonomiska konsekvenser på grund av ökad utrustningskonsumtion. Omvänt hjälper rakare hål att öka produktionsskalorna och minska driftskostnaderna. Anledningen till hålavvikelser variera från anisotropi hos bergformationerna som borras till borrsträngens beteende under påverkan av pålagda krafter. Avvikelser orsakade på grund av berganisotropi är komplexa till sin natur och kan inte kontrolleras till viss del, men avvikelser på grund av mekanik i borrsträngar kan kontrolleras eftersom de ligger i operatörens inflytandeområde. I denna avhandling konstrueras en matematisk 2D-modell som förutsäger borrstångens böjningsbeteende och modellen utökas ytterligare för att förutsäga den böjda profilen för hela borrsträngen. Två olika borrkroneparametrar definieras för att bättre karakterisera hålavvikelsen och förstå borrkronans böjning. Epirocs borrsträngsdata används i den utvecklade modellen och borrsträngens böjda profil studeras. Den utvecklade modellen används för att ytterligare förstå effekten av hålavvikelse för olika borrparametrar som kraften på borrkronan, lutningsvinkel, hållängd etc. Utifrån resultaten drogs slutsatsen att borrsträngens böjstyvhet är den mest kritiska parametern som påverkar hålavvikelsen för Epirocs borrdata och borrsträngsinstallation. Slutligen föreslås potentiella förbättringar och tekniker för att validera resultat som erhållits från den matematiska modellen.

There is a need for objective methods for wrist angular velocity measurements for accurate risk assessments because there is a high frequency of musculoskeletal disorder in workers. The goal of this project was to validate the accuracy of inertial measurement unit sensors to measure the angular velocity. More specifically, the purpose of this master thesis project was to apply an alternative algorithm to compute the markers velocity, other than the one from the optical system that Jenny Wingqvist, and Josephine Lantz used. The project used an experimental data of 10 participants from the previous project done by Jenny Wingqvist and Josephine Lantz. To validate the accuracy, the data of angular velocity of the sensors was compared with the data of angular velocity of markers. The lowest mean value of the root mean square differences value was 23.5 degrees/s during flexion and deviation standard movements at 40 BPM (Beats Per Minute) and the maximum value was 110.5 degrees/s at 140 BPM. The mean value of the correlation coefficients between markers and sensors angular velocities in standard movements of flexion and deviation were 0.85, 0.88, and 0.89 at 40 BPM, 90 BPM, and 140 BPM, respectively. The smallest and the largest mean value of the absolute difference in 50th percentile was found in 40 BPM (19.4±11.3), and 140 BPM (51.2±28.5) respectively. The decorrelation coefficient between the subjects 50th percentile of the angular velocity was 0.91 for the standard movements. The upper limit of agreement for the standard movements was 78.36 degrees/s, while the lower limit of agreement was -13.76 degrees/s.  The results show that the error was too large, so there is a need of further research to measure the wrist angular velocity using IMU sensors.
