Biologisk mångfald är viktigt att främja i den ökade urbaniseringen då det gör att städer kanbibehålla viktiga funktioner när allt fler ytor blir bebyggda och hårdgjorda. Aktörer som harstor inverkan på detta är golfklubbar som ligger i tätbebyggda områden. Golfbanorna är i förstahand områden för golfspel och rekreation, men på grund av de stora ytorna kan delar av banornasom inte i första hand används till spel utnyttjas för främjandet av biologisk mångfald. Syftetmed studien är att undersöka hur och på vilket sätt golfbanor kan fungera som initiativtagareför hållbar utveckling av lokala stadslandskap samt vilken potential golfbanor har för att ökaden biologiska mångfalden i städer. Metoder som använts för att undersöka detta är kvalitativaintervjuer, dokumentgranskning samt observationsstudier. Resultaten visar att golfklubbarnaarbetar på olika sätt med åtgärder för att främja biologisk mångfald. Det är projekt för att ökaarter av pollinatörer, en medvetenhet kring vilka växtarter som bör användas för att främjavariation och samverkan mellan olika lokala aktörer. Men då det råder brist på uppföljning avhållbarhetsarbetet är det otydligt hur pass stor effekt åtgärderna faktiskt har. Studien harkommit fram till att golfklubbar har stor möjlighet att bidra till främjandet av biologiskmångfald och att höja medvetenheten kring hållbarhetsarbete i tätbebyggda områden. / Biodiversity is crucial to preserve during the increased urbanization since it enables cities tomaintain necessary functions when more and more surfaces become exploited. A stakeholderthat can increase biodiversity is golf clubs located in densely built areas. Golf courses areprimary areas for sport and recreation, but due to the large areas that golf courses uses, largeparts of the courses are not used in the game. These areas can instead be used for the promotionof biodiversity. The purpose of this study is to investigate how and in what way golf coursescan function as initiators for the sustainable development of local urban landscapes and whatpotential golf courses have to increase biological diversity in cities. Methods used arequalitative interviews with golf clubs, a review of documents, and an observational study. Theresults show that the golf clubs work in different ways with measures to promote biodiversity.For example, there are projects to increase species of pollinators, awareness of which plantspecies to use to increase variety, and cooperation between different local actors. But due tothe lack of measuring the outcomes of the actions taken, it is uncertain how well the measureswork. The study has concluded that golf clubs have great opportunities to promote biodiversityand raise awareness of sustainability work in densely built areas.

Quantifying the core mechanics of putting is imperative to developing a reliable model that predicts post-collision ball behavior. A preliminary model for the stroking motion of putting and putter-ball collision is developed alongside experiments, establishing an empirical model that supports the theory. The goal of the present study is to develop a correlation between the backstroke of a putt, or the pre-impact translation of the putter, and the post-impact displacement of the golf ball. This correlation is subsequently utilized to generate an algorithm that predicts the two-dimensional ball trajectory based on putt displacement and putting surface texture by means of finite element analysis. In generating a model that accurately describes the putting behavior, the principles of classical mechanics were utilized. As a result, the putt displacement was completely described as a function of backstroke and some environmental parameters, such as: friction, slope of the green, and the elasticity of the putter-ball collision. In support of the preliminary model, experimental data were gathered from golfers of all levels. The collected data demonstrated a linear correlation between backstroke and putt distance, with the environmental parameters factoring in as a constant value; moreover, the data showed that experienced golfers tend to have a constant acceleration through ball impact. Combining the empirical results with the trajectory prediction algorithm will deliver an accurate predictor of ball behavior that can be easily implemented by golfers under most practical applications. Putt distance to backstroke ratios were developed under a variety of conditions.

During the broadcast of a golf tournament, a way to show the audience what a player's swing looks like would be to draw a trace following the movement of the club head. A computer vision model can be trained to identify the position of the club head in an image, but due to the high speed at which professional players swing their clubs coupled with the low frame rate of a typical broadcast camera, the club head is not discernible whatsoever in most frames. This means that the computer vision model is only able to deliver a few sparse detections of the club head. This thesis project aims to develop a machine learning model that can predict the complete motion of the club head, in the form of a swing trace, based on the sparse club head detections. Slow motion videos of golf swings are collected, and the club head's position is annotated manually in each frame. From these annotations, relevant data to describe the club head's motion, such as position and time parameters, is extracted and used to train the machine learning models. The dataset contains 256 annotated swings of professional and competent amateur golfers. The two models that are implemented in this project are XGBoost and a feed forward neural network. The input given to the models only contains information in specific parts of the swing to mimic the pattern of the sparse detections. Both models learned the underlying physics of the golf swing, and the quality of the predicted traces depends heavily on the amount of information provided in the input. In order to produce good predictions with only the amount of input information that can be expected from the computer vision model, a lot more training data is required. The traces predicted by the neural network are significantly smoother and thus look more realistic than the predictions made by the XGBoost model.

I takt med att befolkningen i Stockholmsregionen ökar så ökar även exploateringstrycket på grönytorna i regionen. Ekologisk kompensation har pekats ut som ett verktyg som kan användas för att minska förlusten av biologisk mångfald och ekosystemtjänster i samband med att grönområden exploateras. Syftet med detta arbete har varit att studera hur kommunerna i Stockholmsregionen arbetar med ekologisk kompensation samt vilka möjligheter det finns för att utföra kompensationsåtgärder på golfbanor. Utöver det så har även golfbanornas roll i ett eventuellt system med kompensationspool utforskats. Arbetet har främst bestått av en enkät- och intervjustudie som har kompletterats med en litteraturstudie. Sex stycken kommuner svarade på den utskickade enkäten och ytterligare fyra kommuner deltog i varsin intervju. Två stycken golfklubbar har även deltagit och besvarat ett antal frågor. Baserat på resultaten så drar författarna slutsatsen att golfbanor kan, under rätt förutsättningar, vara recipienter för en rad olika åtgärder för ekologisk kompensation. Exempel på åtgärder som utförts på golfbanor för att bland annat bidra till den biologiska mångfalden har identifierats under arbetet, som exempelvis anläggning av dammar för lekande groddjur. Inga säkra slutsatser kan dras om huruvida golfbanor kan delta i kompensationspooler då det ännu är oklart hur ett sådant system skulle se ut i Sverige. / The population growth in the Stockholm region presents challenges for planners, such as increased exploitation pressure on green spaces in the region. Ecological compensation has been identified as a measure to mitigate damages and minimize net loss of biodiversity and ecosystem services in urban areas. The purpose of this report has been to study to what extent municipalities in the Stockholm region incorporate ecological compensatory actions as well as to unravel any potential in utilizing golf courses as recipients when ecological compensations are to be done. Additionally, the possibilities for golf courses to enroll in compensation pools has been examined. Primary method for this report has been interviews and questionnaires, and has been complemented with a literature study. Six municipalities answered the questionnaire and four municipalities respectively two golf clubs participated in interviews. Based on the results it is concluded that golf courses could be the recipient of various projects of ecological compensation under certain conditions. Such compensatory actions are then dependent on local circumstances. Cases where golf courses are subjects for strategic ecological improvements are described, e.g. construction of ponds that support local amphibian fauna. No conclusions could be drawn regarding whether golf courses could participate in compensation pools due to legal uncertainties on how such a system could be established in Sweden.

Mémoire numérisé par la Direction des bibliothèques de l'Université de Montréal. / Cette étude porte sur le phénomène de chute subite de la performance ("slump") par l'entremise des perceptions de réussite ou d'échec de 20 golfeurs masculins âgés en moyenne de 56,5 ans. Le "slumping" est caractérisé par une emprise émotionnelle qui peut se traduire par une incapacité à rebondir ou à se sortir de piètres performances survenant une âpres l'autre. Le concept de rebondissement implique que le golfeur revient positivement à un niveau satisfaisant de performance suite à un échec initial. En constituant deux groupes de 10 sujets différents en terme de rebondissement, il a été possible de montrer que ce concept est partiellement associé à la notion d'optimisme telle qu'évaluée par le questionnaire cernant le style d'attribution des sujets (ASQ). Un questionnaire portant sur l'anxiété (SCAT) a également été utilisé dans la comparaison, mais aucun résultat significatif n'a pu être obtenu pour différencier les deux groupes de sujets. La présente recherche fait néanmoins ressortir que le phénomène du "slumping", tel que perçu par le golfeur, peut-être opérationalisable et qu'il fait partie intégrante de la performance de l'athlète sur le terrain. Le phénomène n'a pas encore été étudié, d'un point de vue scientifique en sport et les suggestions avancées suite à la réalisation de cette recherche permettront de mieux le cerner pour l'avenir. / This study relates to the phenomenon of the sudden fall in the athletic performance called a "slump", via the perceptions of success or failure of 20 male golfers with an average age of 56.5 years. The slumping is characterized by an emotional influence, which can result in the inability to rebound after a poor golfing performance. The concept of rebound implies that the golfer returns positively to his level of performance with satisfactory results following an initial failure. By setting up two groups of 10 subjects differing in terms of resilience, it was possible to show that this concept is partially associated with the concept of optimism as evaluated by the questionnaire used to determine the style of attribution of each subject (ASQ). A questionnaire relating to anxiety (SCAT) was also used in the comparison, but no significant result could be obtained to differentiate the two groups of subjects. The present research emphasizes nevertheless, that the phenomenon of slumping as perceived by the golfer, forms an integral part of the performance of the athlete on the course. The phenomenon was not previously studied, from a scientific point of view. These results will make it possible for improved golfing performance in the future.

Depuis quelques décennies, plusieurs compagnies manufacturières font face à la compétition intense due à l'importation. Même en adoptant de nouvelles technologies et processus, les économies en main-d'oeuvre dans les pays émergeants, sont difficiles, sinon impossibles à rivaliser. Une piste prometteuse pour la compétitivité est d'offrir des produits et services personnalisés. La première contribution de la thèse est un modèle de personnalisation à huit niveaux. Dans ce modèle, les manufacturiers offrent aux marchés une combinaison d'options des produits, des délais de livraison, des niveaux de service et des prix. Des manufacturiers voulant présenter des offres personnalisées doivent en analyser l'implication sur leurs processus d'affaires. La deuxième contribution de la thèse indique les impacts que chaque type d'offre personnalisée engendre aux processus clefs d'affaires, soit le marketing, la production ou l'approvisionnement. Une fois que les stratégies de personnalisation sont déterminées, le défi est de planifier les besoins en ressources pour supporter les offres personnalisées. La dernière contribution est une méthodologie qui s'adresse à cette problématique. La méthodologie consiste en un heuristique à deux niveaux appuyés sur la simulation du type Monte-Carlo. Le niveau supérieur considère la chaîne de valeurs en entier et des variables au niveau du réseau sont déterminées. Le niveau inférieur configure les ressources pour chaque centre du réseau. Ceci est accompli en simulant simultanément, des plans de production qui satisfont des profils de demande stochastique. L'approche est incorporée dans un logiciel expérimental qui permet à l'utilisateur de modéliser un réseau de centres, leurs offres personnalisées et leurs marchés, afin de trouver une solution dans un temps rapide. La méthodologie est illustrée par un cas dans l'industrie de fabrication de bâtons de golf et les offres permettent de refléter la complexité de la personnalisation.

Spring dead spot (SDS), a monocyclic, soil-borne disease caused by Ophiosphaerella spp., affects the rhizomes and stolons of bermudagrass (Cynodon dactylon L. Pers), and is particularly severe in regions with extended dormancy, such as the transition zone. This research evaluates three aspects of SDS management: environmental influences, disease mapping, and the economic feasibility of precision treatments. To measure the relationship between local topography and SDS localization, UAV imagery was collected from 16 golf course fairways across three locations in Virginia and SDS coordinates were recorded. Using state lidar data, environmental factors such as slope, aspect, annual sunlight, and landform type were quantified. Generalized linear mixed-effects models revealed increased odds of SDS occurrence on north-facing slopes and landforms such as peaks and shoulders (p ≤ 0.001), while pits, valleys, and south-facing slopes were associated with decreased odds (p < 0.001). However, topographic features accounted for only 4.2% of the variance in disease distribution, indicating that other factors also play significant roles in SDS development. In parallel, precision treatment strategies (spot and zonal applications) were evaluated in a randomized complete-block design. Compared to full-coverage and untreated controls, precision treatments achieved similar disease control (p ≤ 0.001) while reducing the treated area by 48–52% (p ≤ 0.001), demonstrating a previously described Python script for spring dead spot detections efficacy in generating actionable disease maps. Finally, the economic viability of precision SDS management was assessed at the Independence Golf Club in Midlothian, VA. Cost analyses comparing precision and conventional treatments showed that a GNSS-equipped sprayer, used for precision applications, provided cost savings over a 10-year horizon when applying isofetamid or a combination product of pydiflumetofen + azoxystrobin + propiconazole. Conversely, this strategy was not cost-effective with annual applications of tebuconazole due to its low cost per application. These findings suggest that adopting precision treatment methods with appropriate fungicides can reduce costs and improve sustainability in SDS management. Together, these studies highlight the potential for integrating disease mapping, environmental analysis, and economic modeling to optimize SDS management strategies in turfgrass systems. / Doctor of Philosophy / Spring dead spot (SDS) is the most economically important disease of bermudagrass in the United States. It is caused by Ophiosphaerella spp. of fungi, which infect the horizontal growth structures of the plants causing damage in the fall leaving plants more susceptible to damage over the winter, these areas then fail to emerge from winter dormancy. Damage from SDS is often severe and long lasting making it important to avoid. While SDS has been well-studied, many important questions remain, including ways to improve management efficiency with fungicides and the reasons the disease develops where it does. To address questions on precision management we used a previously described Python script to build custom disease maps of SDS on golf course fairways. We looked at 16 fairways across 3 different locations in Virginia and treated them with either full-coverage applications, precision spot or zonal treatments based on the script, or left them untreated. Fairways treated with the spot and zonal treatments showed similar SDS suppression to full-coverage treatments the following year while using an average of 49% less fungicide. Next, we targeted concerns held by golf course superintendents. The first of these projects looked at the economic viability of these precision treatments over an entire golf course. To answer this, we recorded the amount of labor and money associated with precision treatments over an entire 18-hole course and found that the net present value over 10 years of purchasing a new GNSS sprayer for precision applications could be less than purchasing a new conventional sprayer for traditional applications. Finally, many golf course superintendents will say that SDS occurs more often on north-facing slopes. We looked at SDS locations in fairways that received little to no treatment previously and compared that to topography data. We found that while north-facing slopes and several other factors including the shape of the land itself were more likely to have SDS, the degree to which this is the case is not biologically relevant. These projects together highlight the complex nature of SDS and show that while its biology is complex, it is possible to control using precision turfgrass management techniques.
