This diploma thesis deals with the tracking of objects using a robotic manipulator Epson C3 and a color camera. The work describes the basic qualities of the device to be used. The OpenCV library and its wrapper EmguCV are used as software tools for computer vision. It discusses the basic issues and principles of tracking objects in the image and introduces some methods of tracking. These methods have been tested and therefore their strengths and weaknesses, which appeared during testing, are listed here. Furthermore, there is a procedure for calculating the new coordinates of the camera and the manipulator effector using homogeneous transformations. The work contains the results of testing the algorithms and their evaluation. The output of the work is a test application for the Epson C3 robot.

<p>Points-to analysis is a static program analysis which computes possible reference relations between different parts of a program. It serves as input to many high-level analyses. Points-to analyses differ, among others, in flow- and context-sensitivity, program representation, and object abstraction. Most program representations used for points-to analysis are sparse representations which abstract from, e.g., primitive data types and intra-procedural control-flow. Thus, a certain degree of information is sacrificed for compact program representation, which results in scalable performance. In this thesis, we present a framework which allows building different versions of Points-to SSA (P2SSA), a sparse, Memory SSA based program representation. Distinct instantiations of P2SSA contain different levels of abstraction from a program's full representation. We present another framework which allows running Points-to analyses on these program representations. We use these two frameworks to instantiate different versions of P2SSA and compare them in terms of analysis precision and execution time.</p>

A hacker might use a rogue access point to gain access to a network, this poses athreat to the individuals connected to it. The hacker might have the potential to leakcorporate data or steal private information. The detection of rogue access points istherefore of importance to prevent any damage to both businesses and individuals.Comparing different software that detects rogue access points increases the chanceof someone finding a solution that suits their network. The different type of softwarethat are compared are intrusion detection systems, wireless scanners and a Ciscowireless lan controller. The parameters that are being compared are; cost, compat-ibility, detection capability and implementation difficulty. In order to obtain resultssome of the parameters require testing. As there are three types of software, threeexperiment environments should be conducted. Our research indicates that alreadyexisting network equipment or the size of the network affects the results from theexperiments.

Recently, the role of guilt within interpersonal relationships has come under scrutiny. This research, though informative, has been primarily gleaned from retrospective accounts. This investigation examines guilt virtually as it is elicited in friendship and significant-other dyads, probing the following issues: (a) experienced guilt and perceptions of conversational appropriateness as they relate to relational satisfaction and relational interdependence, (b) the association between elicitors' and targets' perceptions of relational transgression and relational satisfaction, (c) elicitors' perceptions of predicted and actual outcomes of guilt elicitation, (d) effects of guilt elicitation on targets' perceptions of the relationship, (e) self-esteem's effect on targets' experienced guilt, and (f) effects of relationship type (i.e., friends vs. significant others) on the above. Results indicate that relationship type is associated with intensity of the guilt appeal, and is a factor in the link between relational interdependence and perceptions of a guilt appeal's appropriateness. Additionally relationship type, relational interdependence, and relational satisfaction offered some demonstration of moderating the usage and reception of guilt. Relational satisfaction evidenced no association with partners' perceptions of the relational transgression, while self-esteem demonstrated a near significant association with experienced guilt. Content analyses of elicitors' perceptions of predicted and actual outcomes and targets' perceptions of relational meanings of guilt appeals are presented.

Rouse, Susan L. "A Comparison of Points Versus Sounds as Reinforces in Human Operant Research." Thesis, University of North Texas, 1999. https://digital.library.unt.edu/ark:/67531/metadc278951/.
Der volle Inhalt der QuelleAnnotation:
Research shows that human operant behavior typically differs from non-human operant behavior on schedules of reinforcement. These differences in performance may be related to differences between the experimental preparations used to study human and non-human operant behavior. One such difference is the type of reinforcer used. This experiment analyzed the differential effects of points alone, points backed up by money, and sounds on schedule performance of human subjects. Results show that sounds generated moderate rates of responding, capable of change in either direction. When points backed up with money were the reinforcers, however, high rates of behavior were generated, disrupting the previously established baseline performance. This suggests that while points may be effective in generating high rates of behavior, they may be ineffective in producing sensitive baselines needed to study human operant behavior on schedules of reinforcement.

This thesis uses experimental archaeology as a method to discover the functional differences between Clovis and Folsom projectile points filtered through a behavioral ecology paradigm. Porcelain is used as a substitute for tool stone for its consistency and control value. The experiment was devised to find out which technology, Clovis or Folsom, was more functional, had a higher curation rate and contributed to increased group subsistence. Paleoindian tool technology transitions can be seen as indicators for adaptation triggered by environmental conditions and changes in subsistence. Folsom technology, when compared to Clovis technology, was functionally superior in performance, refurbishment and curation. Technological design choices made by Folsom people were engineered toward producing a more functional tool system as a sustainable form of risk management. The Clovis Folsom Breakage Experiment indicates that Folsom tool technology was specifically adapted to bison subsistence based on increased functionality and curation.

This study investigates the effects of institutional structure on the privacy rights regimes in the United States and the United Kingdom, from 2000-2006. The goal of this research is to analyze how variation in the institutional arrangements across these two countries allowed for more or less protection of privacy rights for citizens. Domestic terrorist attacks during the time period represent a catalyst for changes in police and government surveillance activities. Veto points literature provides the framework for institutional comparison. The first part of the research provides a discussion of the historical evolution of privacy rights in both states, focusing on government and police surveillance and investigations. The second part of the research, based on veto points theory, compares the institutional arrangements of the United States and the United Kingdom, and suggests that the number of veto points and the ideological proximity of veto players have had an effect on the formulation of policy. Laws governing surveillance, investigations and privacy in the year 2000 provide a benchmark for analyzing how policies change over time.<br>M.A.<br>Department of Political Science<br>Sciences<br>Political Science MA

"Benchmarking significant DBMS costs on Niagara in order to perform a relative performance comparison between the Shared Nothing and the Shared Everything DBMS memory architectures." Thesis, Norwegian University of Science and Technology, Department of Computer and Information Science, 2006. http://urn.kb.se/resolve?urn=urn:nbn:no:ntnu:diva-9310.
Der volle Inhalt der QuelleAnnotation:
<p>This report carries out a relative performance comparison between two DBMS architectures on the Multi Core, Single Die (MCSD) realization Niagara. The two DBMS architectures in question are Shared Nothing (SN) and Shared Everything (SE). The MCSD field is rapidly evolving, and we expect that this technology will become increasingly important in the near future. In order to carry out the comparison, the performance of the architectures must be calculated. This calculation depends on the cost figures associated with each architectural approach. To identify these costs, we present the design solutions made and results discovered in our previous work. Based on this, the most significant costs are determined and scheduled to be micro benchmarked. The natural next step is to examine possible techniques to implement the benchmarks. In order to do this, we first expand on the Niagara chip and the platform on which the micro benchmarks will run. Having a sufficient theoretical platform to continue, we move on to describe the implementation of each micro benchmark in detail. After benchmarking all the most significant costs, we thoroughly discuss the results, some of which are indeed surprising. The costs which are not benchmarked are based on assumptions from our previous work and recalculated to apply to Niagara. For both SN and SE, we evaluate the system for two classes of transactions. The first class is transactions touching one tuple (called simple), the second is transactions touching four tuples (called complex). Each class has two instances, read and update. In order to perform the subsequent analysis, the decomposition of each transaction is presented in detail. When analyzing the outcome of the calculations, interesting results emerge. First, we note that SE is the cheapest alternative when evaluating the simple transactions. This is because the SN approach includes an administrative overhead component that does not pay off when the transaction only touches one tuple. However, for complex transactions, the overhead component results in a parallel gain for SN which outperforms SE. Based on the most dominant costs of both architectures, we perform a sensitivity analysis. For SN, the analysis is based on the cost for message passing. For SE, it is based on the cost for synchronization. The goal of this analysis is two folded. First, it is interesting to see how the results vary. For example, what the ratio between the cost for message passing and the cost for synchronization must be in order to make the two approaches perform equally well. Second, the analysis indicate how error-prone each architecture is to erroneous estimation. The sensitivity analysis examine the performance of SN and SE when the ratio between the cost for message passing and the cost for synchronization is varied. This is done in both the read and the update cases. In addition to examining the simple and the complex transactions, we examine general transactions were the number of operations are not predetermined. The analysis of the general read transaction suggests that when the number of operations increases, the message passing and synchronization costs wipe out the impact of the other costs. It also suggests that when the cost of message passing is greater than 4 times the cost of synchronization, SE performs better when increasing the number of read operations. Similarly, if message passing is cheaper than 4 times the cost of synchronizing, SN is preferable. When increasing the number of update operations, the ratio is 3.33. After concluding the analysis, we suggest a hybrid architecture that might combine the advantages of SN and SE. At the cost of introducing both message passing and synchronization, the architecture introduce parallelism in SE. Lastly, we identify suggestions for future work. Realized and applied to the DBMS model introduced in this report, we believe that several of these suggestions can shrink some of the costs presented.</p>

Der volle Inhalt der QuelleAnnotation:
Background: Removal of teeth results in both horizontal and vertical changes of hard and soft tissue dimensions. The magnitude of these changes is important for decision-making and comprehensive treatment planning, with provisions for possible solutions to expected complications during prosthetic rehabilitation.
Objectives: to review all English dental literature to assess the magnitude of dimensional changes of both the hard and soft tissues of the alveolar ridge up to 12 months following tooth extraction in humans.
Materials and methods: An electronic MEDLINE and CENTRAL search complemented by manual searching was conducted to identify randomised controlled clinical trials and prospective cohort studies on hard and soft tissue dimensional changes after tooth extraction. Only studies reporting on undisturbed post-extraction dimensional changes relative to a fixed reference point over a clearly stated time period were included. Assessment of the identified studies and data extraction was performed independently by two reviewers. Data collected were reported by descriptive methods. Weighted means and percentages of the dimensional changes over time were calculated where appropriate.
Results: The search provided 3954 titles and 238 abstracts. Full text analysis was performed for 104 articles resulting in 20 studies that met the inclusion criteria. In human hard tissue, horizontal dimensional reduction (3.79 ± 0.23 mm) was more than vertical reduction (1.24 ± 0.11 mm on buccal, 0.84 ± 0.62 mm on mesial and 0.80 ± 0.71 mm on distal sites) at 6 months. Percentage vertical dimensional change was 11-22 % at 6 months. Percentage horizontal dimensional change was 32% at 3 months, and 29-63% at 6-7 months. Soft tissue changes demonstrated 0.4-0.5 mm gain of thickness at 6 months on the buccal and lingual aspects. Horizontal dimensional changes of hard and soft tissue (loss of 0.1 mm to 6.1 mm) was more substantial than vertical change (loss 0.9 mm to gain 0.4mm) during observation periods of up to 12 months, when study casts were utilised as a means of documenting the changes.
Conclusions: Human re-entry studies showed horizontal bone loss of 29-63% and vertical bone loss of 11-22% after 6 months following tooth extraction. These studies demonstrated rapid reductions in the first 3-6 months that was followed by gradual reductions in dimensions thereafter.<br>published_or_final_version<br>Dental Surgery<br>Master<br>Master of Dental Surgery

Der volle Inhalt der QuelleAnnotation:
Cette thèse présente trois contributions en lien avec l'apprentissage et la détection de dissimilarité statistique multivariée, problématique d'importance primordiale pour de nombreuses méthodes d'apprentissage utilisées dans un nombre croissant de domaines. La première contribution introduit la notion de taille d'effet multivariée non-paramétrique, éclairant la nature de la dissimilarité détectée entre deux jeux de données, en deux étapes. La première consiste en une décomposition d'une mesure de dissimilarité (divergence de Jensen-Shannon) visant à la localiser dans l'espace ambiant, tandis que la seconde génère un résultat facilement interprétable en termes de grappes de points de forte discrépance et en proximité spatiale. La seconde contribution présente le premier test non-paramétrique d'homogénéité séquentiel, traitant les données issues de deux jeux une à une--au lieu de considérer ceux-ci- in extenso. Le test peut ainsi être arrêté dès qu'une évidence suffisamment forte est observée, offrant une flexibilité accrue tout en garantissant un contrôle del'erreur de type I. Sous certaines conditions, nous établissons aussi que le test a asymptotiquement une probabilité d'erreur de type II tendant vers zéro. La troisième contribution consiste en un test de détection de changement séquentiel basé sur deux fenêtres glissantes sur lesquelles un test d'homogénéité est effectué, avec des garanties sur l'erreur de type I. Notre test a une empreinte mémoire contrôlée et, contrairement à des méthodes de l'état de l'art qui ont aussi un contrôle sur l'erreur de type I, a une complexité en temps constante par observation, le rendant adapté aux flux de données<br>In this thesis, we study problems related to learning and detecting multivariate statistical dissimilarity, which are of paramount importance for many statistical learning methods nowadays used in an increasingly number of fields. This thesis makes three contributions related to these problems. The first contribution introduces a notion of multivariate nonparametric effect size shedding light on the nature of the dissimilarity detected between two datasets. Our two step method first decomposes a dissimilarity measure (Jensen-Shannon divergence) aiming at localizing the dissimilarity in the data embedding space, and then proceeds by aggregating points of high discrepancy and in spatial proximity into clusters. The second contribution presents the first sequential nonparametric two-sample test. That is, instead of being given two sets of observations of fixed size, observations can be treated one at a time and, when strongly enough evidence has been found, the test can be stopped, yielding a more flexible procedure while keeping guaranteed type I error control. Additionally, under certain conditions, when the number of observations tends to infinity, the test has a vanishing probability of type II error. The third contribution consists in a sequential change detection test based on two sliding windows on which a two-sample test is performed, with type I error guarantees. Our test has controlled memory footprint and, as opposed to state-of-the-art methods that also provide type I error control, has constant time complexity per observation, which makes our test suitable for streaming data

碩士<br>國立交通大學<br>資訊工程研究所<br>83<br>An algorithm for computing the surface intersection between two
general parametric surfaces is proposed. Th algorithm consists
of two steps. In the first step, we find the significant points
- u-turning and border points. The second step traces the curve
component in a numerically stable manner. It is well recognized
that a good surface intersection algorithm should balance three
conflicting objectives: robustness, accuracy, and efficiency.
The proposed alogrithm is robust because it can find at least
one starting point for each intersection component by locating
the significant points. Morever, in tracing process, our
proposed alogrithm should be more efficient because we obtain
the tracing direction explicitly. Nevertheless, we observe that
computing the significant points for NURBS surfaces is not
efficient, especially for high degree surfaces. Also, as shown
in other existing methods singularities cannot be completely
resolved although the employed tracing procedure is capable of
handling many of the singularities.

碩士<br>國立交通大學<br>網路工程研究所<br>100<br>To evade VM-based malware analysis systems, VM-aware malware equipped with the ability to detect the present of virtual machine is proposed. To detect VM-aware malware and locate VM-sensitive divergence points of VM-aware malware, we propose a new block-based behavior comparison scheme (BBC), in contrast to the conventional instruction-based schemes. The BBC scheme divides the malware program into basic blocks, instead of binary instructions, and uses them as the analysis unit. In contrast to the conventional schemes, the BBC scheme significantly decrease the cost of behavior logging and trace comparison, as well as the size of behavior traces. In our evaluation, behavior logging is 23.87-39.49 times faster than the conventional schemes. The total number of analysis unit, which is highly related to the cost of trace comparisons is 11.95%-16.00% of the conventional schemes. Consequently, VM-sensitive divergence points can be discovered in a more efficient way. The correctness of our divergence point discovery algorithm will be also proved in this paper.

碩士<br>亞洲大學<br>資訊工程學系<br>107<br>In recent years, the number of people dying from cardiovascular diseases is increasing, and it is a disease that cannot be ignored. Cardiovascular disease has no particularly obvious symptoms before onset and is often overlooked. Clinically, doctors can check whether a patient has cardiovascular disease through a sports ECG. The exercise ECG is an electrocardiogram and blood pressure and heart rate that allow the patient to walk on the treadmill and record their movement status. In the literature, the accuracy of doctors using cardiovascular electrocardiography to diagnose cardiovascular disease falls to about 70-75%. In this paper, we study the use of various machine learning classification algorithms for the analysis of exercise ECG data. The experimental data is data from 100 patients with suspected and known coronary artery disease who underwent exercise electrocardiography after a doctor's diagnosis. We use five machine learning classification algorithms: K-Nearest Neighbor (KNN), Decision Tree (DT), Random Forest(RF), Support Vector Machine(SVM) and eXtreme Gradient Boosting (XGBboost). As a result of the experiment, the XGBboost classifier has the highest performance in all classification models and can achieve an accuracy rate of 84%. The results show that machine learning methods can be used to assist doctors in improving the accuracy of cardiovascular disease diagnosis.

碩士<br>育達商業技術學院<br>企業管理所<br>97<br>With 3C products and Internet communications technology rapid development, people use mobile phones to change the requirements of novelty. At the same time, enterprises face the increasingly fierce competitive environment in recent years and so need to have a clear positioning strategy. Therefore, this study will be referred Hill and Jones (2001) to a competitive advantage - value, innovation, quality, customer response, to explore the mobile phone brand awareness in the consumer industry position.
In this study, all mobile phone users and potential consumers will be the research sample. There are the seven well-known mobile phone brands selected according to the consumers’ familiarity in the market. Through the convenience sampling method the consumers are adopted to collect data. A total of 144 questionnaires were issued, and 127 valid questionnaires were received. Orthosim 2 v.01 was used to analyze the comparison of two figures in order to establish the dynamic model in the study. NewMDSX software was used for the survey analysis of preferences <MDPREF> and ideal point analysis <PREFMAP> to explore the strategy of the brand positioning and consumer preferences.
Dynamic model found the past and current customers in the mobile phone brands’ positioning strategy is consistent under α = 0.001 statistical significant level. However the current and future customers in the mobile phone brands’ strategy is not consistent under α = 0.001 statistical significant level and is consistent under α = 0.05 statistical significant level. Although the environment and time changed, the customer's habits and needs to buy the mobile phone brands have not changed. iP at this stage needs to strengthen the market positioning. It maybe because iP is a new brand and not so clear positioning in the market. It seems that Samsung needs to strengthen its strategic positioning in the past market and Sony Ericsson needs to strengthen its strategic positioning in the future market.

M.Tech. (Chiropractic)<br>Myofascial pain syndrome has become a significant cause of chronic pain and disability in today‟s society. Conditions causing chronic pain can not only cause disability due to pain, but can also lead to other problems such as psychological and behavioural disturbances. Physical deconditioning can also occur due to lack of exercise because of myofascial pain (Rachlin, 1994). The aim of this study was to compare dry needling therapy and ultrasound therapy in the treatment of myofascial trigger points in order to demonstrate any superiority between the two modalities. Participants for this study were recruited by word of mouth and advertisements that were placed around the University of Johannesburg Doornfontein Campus. Thirty people participated in the trial, all of whom conformed to the specific inclusion and exclusion criteria. The participants were randomly placed into two groups. Group A received dry needling therapy, namely the fanning technique, and Group B received ultrasound therapy. Participants in Group A received one treatment per week for four weeks and subjective and objective measurements were taken at each visit. Participants in Group B received two treatments per week for three weeks and measurements were taken at visits one, three, five and seven. Subjective data was obtained through the use of the Visual Analogue Pain Scale, which measured the perception of pain of the participants. Objective data was obtained from pressure algometer readings, which measured pain pressure thresholds of participants, and through the Cervical Range Of Motion (CROM) device. The results of this study indicated that dry needling therapy and ultrasound therapy both significantly benefited participants in terms of the treatment of active myofascial trigger points. Based on the final results, both dry needling therapy and ultrasound therapy are equally effective modalities in the treatment of active myofascial trigger points, with neither modality showing superiority over the other.

Der volle Inhalt der QuelleAnnotation:
M.Tech.<br>Purpose: Acupuncture has been a controversial issue in the medical world for many years before the sceptic western medicine slowly adopted its idea. Some mechanisms for pain relief were clinically researched and proven to be valid as well as effective in treating tension-type headaches (Stux, Berman and Pomerantz, 2003) The purpose of this study was to assess and compare the effects of cervical spine manipulation and needling of acupuncture points in those patients with tension-type headache and suggest another complimentary treatment to the chiropractic manipulation, especially in those patients where manipulation is contraindicated to manipulation. If found to be effective, various mechanisms have been suggested in the formation of tension headache episodes. Those mechanisms may be alterations within the spinal cord and/or brainstem gating mechanisms as a result of facet joint dysfunction, sensitization of nociceptors in the peripheral structures of the body and psychological factors. Method: This study consisted of two groups, consisting of 16 subjects in each group. All participants were screened for tension-type headaches and accepted based on the inclusion and exclusion criteria. The subjects were between the ages of eighteen and thirty-five. Group 1 received chiropractic manipulation treatment to the most restricted levels in their cervical spine. Group 2 received treatment consisting of needling of acupuncture points to specific predetermined points. Procedure: Each successful candidate was treated six times over a 3 week period which included a total of seven sessions. Before the beginning of the treatment, the successful candidate completed the Vernon-Mior Neck Pain and Disability Index Questionnaire and the Numerical Pain Rating Scale. Readings for cervical spine ranges of motion were then taken with a CROM device. In group 1, chiropractic manipulation was then delivered to the most restricted segments in the cervical spine. In group 2, needling of six predetermined acupuncture points for relieving tension-type headache was performed bilaterally. The same treatment procedure was administered at sessions one through six, the CROM readings and questionnaires were taken in sessions one, three, five and seven. Results: The results were obtained by using the Mann-Whitney U and t-test. No statistically significant differences were identified between the groups, when comparing the 2 treatment methods at the visits. However, both groups showed a statistically significant improvement over time within each group individually for subjective measurements and for right lateral flexion in the objective measurements. Conclusion: The results were inconclusive with regards to the prolonged effects of chiropractic manipulation and needling of acupuncture points on cervical spine range of motion in patients with tension-type headache. However, it was concluded that both methods of treatment had beneficial effects on how the participants perceived their pain and disability. Due to the small group of subjects and relatively short duration of the study, accurate conclusions could not be formulated. The findings obtained were insignificant and further research needs to be performed on the effects of cervical spine manipulation and needling of acupuncture points on those suffering with tension-type headache.

Abstract
This research intended to examine the scoring technique of the eight finalists in the Women’s Singles in Table Tennis in Rio 2016 (2016 Summer Olympics), and to provide the results as references to table tennis athletes for training in the future. The observation method is used as research methodology with the records of three-stage techniques in the contest in 2016 Rio as objects to find out the technical performances of the eight finalists in women’s table tennis singles. The related variables include: the scoring rate for the stage in serving the ball to attack, the scoring rate for the stage in receiving the serve to attack, and the scoring rate for the standoff stage; the using rate of serving the ball to attack, the using rate for the stage in receiving the serve to attack, and the using rate for the standoff stage; the weight scoring rate for the stage in serving the ball to attack, the weight scoring rate for the stage in receiving the serve to attack, and the weight scoring rate for the standoff stage. The collected data will be analyzed with descriptive statistics and t-test. The results discovered that 1. The evaluation of the athletes in the three-stage techniques: the performance of attack-type athletes is good in the scoring rate for the stage in serving the ball to attack, failing for the stage in the scoring rate of the stage in receiving the serve to attack, good for the stage in the scoring rate in the standoff stage, comparatively low for the stage in using rate in serving the ball to attack, comparatively low for the stage in the using rate of receiving the serve to attack, and comparative high for the stage in for the standoff stage. 2. The difference of athletes’ performance of three-stage techniques: there was no significant difference for the attack-type athletes and chopping-type athletes. There were significant differences in the four variables of the scoring rate for the stage in serving the ball to attack, the scoring rate for the stage in receiving the serve to attack, the scoring rate for the standoff stage, and the weight-scoring rate for the standoff stage. Moreover, the winners tend to perform better than the losers. 3. The major technical factors that affect the attack type athletes were the weight scoring rate for the standoff stage. Suggestions: training in the techniques of attack and defense for the standoff stage should be enhanced, with the stage in serving the ball to attack as the core of technical training to highlight the strong point in the technique. In addition, the techniques for the stage of serving the ball to attack of individual should also be promoted.

This diploma thesis titled ?Application of the geodetical method and GNSS method for land location? deals with the topic of laying reference points of lands using the traditional geodetical method and the method integrating the GNSS technology. The comparison of the used methods focuses mainly on the productivity, efficiency and accuracy of the geodetical work. The initial preparatory works included reference points evaluation and recognition. After that a coordinate frame of reference points was established for the use of the geodetical method. The final layout of the reference points was performed by means of the geodetical method as well as the GNSS method employing the permanent measuring station Czepos. The average coordinates fault was taken into account when the accuracy of the coordinates position was analyzed. The laid reference points were used to maintain the actual land cadastration.

Dissertação de Mestrado em Contabilidade e Finanças apresentada à Faculdade de Economia<br>Este trabalho consiste numa análise da relação entre os resultados desportivos dos três maiores clubes portugueses e as variações do valor das ações de mercado dessas instituições. Foram usados modelos que se baseiam nos pontos não esperados obtidos na Liga Portuguesa, Liga dos Campeões e Liga Europa (baseados num modelo que usa as “odds” de apostas para calcular os pontos esperados para cada jogo), sendo que esses pontos não esperados são usados apenas com base no jogo mas também em conjunto com uma variável que calcula a importância do jogo para os objetivos das equipas. Foi também criada a variável de comparação de probabilidades, baseada nas “odds” para a equipa se qualificar em fases a eliminar de competições europeias e usadas para estudar os jogos deste género. Foi usado um modelo GARCH para este estudo. Estas variáveis têm um impacto significativo no valor das ações do Sporting, que apresentam uma valorização significativa quando os resultados da Liga dos Campeões são positivos, no entanto um progresso para as fases a eliminar da Liga Europa causaria um efeito negativo. Quanto aos resultados do Benfica, há indícios de que os resultados positivos na Liga Portuguesa, da Liga dos Campeões e da Liga Europa têm um efeito positivo no valor das ações, sendo que ser eliminado da Liga dos Campeões, mesmo que signifique ir à fase a eliminar da Liga Europa, tem um efeito negativo. Os resultados do Porto, no entanto, levam a concluir que os resultados dos jogos não têm efeito nas ações da sociedade anónima desportiva.<br>This work consists on the analysis of the relation between the three biggest Portuguese football clubs’ match results and their stock value fluctuations. To do so I use models that consider Portuguese League’s, Champions League’s and Europa League’s unexpected points (based on a model that uses betting odds to calculate expected points for each game) unweighted and weighted by the teams’ objectives in each competition and the odds for qualifying a knockout stage, which is going to be called the probability comparison variable and is used to study the results of these type of European competitions’ games. The study is made using a GARCH model. Results show that these variables have a significant impact on Sporting’s stock value, which show a significant improvement when the team achieves positive results in the Champions League, whether it's in the group stage or the knockout stage, however a qualification for the Europa League knockout stage would have a negative impact on this entity’s stock value. As for Benfica, the results show a positive effect if the team achieves its goals in the Portuguese League, Champions League and Europa League, but being eliminated in the Champions League group stage, even if it translates to a qualification for the Europa League knockout stage, would be a negative outcome that would affect negatively the club’s stock value. On the other hand, Porto’s models indicate that the team’s performances on these competitions don’t affect the sporting entity’s stock value.
