Повний текст джерелаLa dynamique de polymères réticulés de stress, telles que celle qui compose le caoutchouc, n'est pas encore bien comprise. Une combinaison de techniques homodynes et hétérodynes de rayons x coherentes est utilisé pour mesurer les fluctuations du système, une fois étiré. La combinaison des deux techniques permet la mesure des régimes d'écoulement, ainsi que le caractère aléatoire du système. Après l'analyse des données, les résultats montrent que les mesures ont réussi à capturer cet information. La vitesse d'écoulement a été découverte de contenir une nature en fonction du temps semblable à celle de la courbe contrainte-déformation. Après la vitesse d'écoulement a été extraite, la nature aléatoire du système a été analysé. Cette motion a été découverte au hasard de ne pas être dominé par la diffusion classique, mais de certains processus aléatoires plus lents.

Working with Gillette Corporation, an automated mechanical testing tool that bent a small flat piece of steel was designed. The design of the tool was an effort to improve upon previous generations of the same tool. It consisted of three main elements; a servomotor, connected to a torque transducer, which was connected to a break device. A thin piece of steel was loaded into the break device and the motor was activated, moving a flipper arm on the device which bent the steel. While bending this piece of steel, the torque transducer would relay torque and angle information to a computer. This information was collected and displayed in Excel as torque versus angle plots, which would show the moment at which the piece of steel was broken. This entire process was automated so that after loading the steel, one click of a button would run one test. Razorblades were primarily bent with the device until they would break, and for this reason, the measuring tool was called the 'blade break test.' The work consisted of designing a robust mechanical system coupling the three devices mentioned above in series. Code was written in Visual Basic that managed all the individual devices in the measuring tool, getting them to work together and linking them with a computer.
(cont.) A user interface was designed with engineers in mind, imbedding automated data collection and representation through Excel. Finally, a manual was created accompanying the device so other engineers could use, troubleshoot, and modify the 'break test.' The result of this project was the creation of a successful measuring instrument with full documentation and functionality.

Auffret, Thomas. "Mesure et juste mesure chez Platon." Thesis, Paris 1, 2014. http://www.theses.fr/2014PA010569.
Повний текст джерелаTwo mathematical notions seem to structure Plato’s theory of measure. The first one is a postulate, usually known as the “Eudoxus axiom”, the other an algorithm called “anthuphairesis”. Both of them belonged to the mathematical theory developed by Theaetetus expanding Theodorus’ logistics. The main hypothesis of this work is that they constitute the core of Plato’s response against the Homo mensura thesis elaborated by Protagoras. We have thus proposed to replace Protagoras’ theory in the enlarged context of a serious crisis affecting the logical consistency of the mathematical notion of measure, provoked by the discovery of incommensurable magnitudes as well as non–Archimedean sets, exemplified by mixtilinear angles. This implied to examine anew the links between ancient sophistic and mathematics, and particularly Plato’s critics against Hippias’ quadratrix. It was also required to study the close relation between platonic dialectic and the new art of measurement exposed by Plato in the Statesman. Thus, by studying some passages mainly taken from Plato’s last dialogues, an attempt has been made to show how the higher art of measurement could inform dialectics. Plato’s theory of division, as well as the analysis and the generation of the mixed structures which constitute the universe, the city and the individual man have thus been tentatively reduced to this model

Повний текст джерелаA number of clinically relevant variables (plantarflexion MVC, dorsiflexion MVC, range of motion, passive torque, K offset, low K region, and the intercept of the K-absolute torque relation) were shown to be reliable. In addition, the results of the case study demonstrated that it would be feasible to use these experimental procedures and analytic methods on individuals who have sustained orthopedic trauma. Finally, certain variables (the K offset, the slope and intercept of the K-torque relation, and a low stiffness region) appeared to be sensitive to the clinical changes associated with orthopedic pathology.

Повний текст джерелаO complexo articular do tornozelo e pé é o local mais comumente afetado por lesões traumáticas ou por sobrecarga em vários contextos, sejam eles esportivos ou situações rotineiras da vida diária. Essas lesões frequentemente causam limitações funcionais por longos períodos, sendo que em alguns casos elas podem gerar sequelas permanentes. O impacto que as lesões, doenças e quaisquer agravos podem gerar sobre a saúde, especialmente sobre a funcionalidade e a qualidade de vida, deve ser abordado no escopo da avaliação clínica na área da saúde. Quantificar esse impacto funcional representa um desafio e uma meta para clínicos e pesquisadores da área, os quais têm utilizado os instrumentos de avaliação baseados no cliente com o intuito de suprir essa necessidade. Os questionários e escalas funcionais são ferramentas que tem a capacidade de abranger os domínios da atividade e participação, sendo capazes de transformar medidas subjetivas em dados objetivos. O questionário Foot and Ankle Ability Measure (FAAM) foi identificado como um dos melhores instrumentos de avaliação já desenvolvidos para quantificar a funcionalidade de indivíduos acometidos por desordens músculo esqueléticas do complexo tornozelo/pé, mas ainda não está disponível para uso no Brasil. O FAAM é composto por duas escalas, sendo uma para avaliação da funcionalidade em atividades da vida diária (Escala de AVD) e a outra para atividades esportivas (Escala de Esportes). O objetivo deste estudo foi fazer a tradução e adaptação transcultural do FAAM, bem como realizar a análise psicométrica da versão brasileira desse instrumento. A avaliação da validade do instrumento foi feita com a aplicação do modelo Rasch, além das análises de confiabilidade teste re-teste e consistência interna com o cálculo do Coeficiente de Correlação Intra-classe (CCI) e do Alfa de Cronbach, respectivamente. As propriedades psicométricas do FAAM-Brasil foram analisadas após a aplicação do questionário em 55 voluntários, de ambos os sexos, com média de idade de 34 anos, acometidos por desordens músculoesqueléticas do complexo tornozelo/pé. O FAAM-Brasil apresentou o CCI1,1 de 0,88 e 0,82 e o Alfa de Cronbach de 0,93 e 0,90, para as escalas de AVD e Esportes, respectivamente. A análise Rasch indicou coeficientes de confiabilidade de 0,92 e 0,88 para os indivíduos nas escalas de AVD e Esporte, respectivamente, e para os itens os valores foram 0,95 e 0,94, para cada escala, nessa mesma ordem. Dos 29 itens que compõem o instrumento, dois da escala de AVD (9,5%) e dois da escala de Esporte (25%) não atenderam aos pressupostos do modelo, o que sinalizou um comprometimento da validade de construto do instrumento. O índice de separação dos itens da escala de AVD foi de 4,17 e para a escala de Esporte foi de 3,89. Para a escala de AVD, o índice de separação dos sujeitos foi de 3,4 e de 2,71, para a escala de Esporte. O tempo médio de aplicação foi de sete minutos. A versão brasileira do FAAM mostrou ser válida e confiável para ser aplicada na população brasileira, mas os resultados da análise Rasch indicam que alguns itens apresentaram inadequações para a amostra estudada, pois apresentaram padrão errático de resposta. Por isso, o FAAM-Brasil deve ser aplicado com cautela em indivíduos que praticam esportes diferenciados, cujas demandas físicas diferem das tarefas descritas nos itens da escala de Esporte.

Повний текст джерелаVarious ways exist whereby balance abilities of the individual can be assessed. However, most of these are subjective methods. This thesis strives to demonstrate the effectiveness of a new device, the Dorsiflexometer that can be used to objectively assess one’s balance abilities. The Dorsiflexometer was constructed and mathematically modelled using appropriate simplifying assumptions. After its construction, the Dorsiflexometer was tested using two experimental set-ups to obtain raw data. Both these set-ups consisted of the two tiltable platforms equipped with three load cells each, the bridge amplifiers and the personal computer (PC). The only difference in the two experimental set-ups is in the type of test that was performed as well as the bridge amplifiers used. Numerous parameters, such as the radius of movement and the Lyapunov number can be extracted from the raw data. A computer program was written to analyse the raw data and present the results in a user-friendly manner. A new parameter, the Sway Index, was used to obtain a single balance value for the tested individual. This parameter proved useful in quantifying balance. An advanced patent search was carried out before the device was constructed. This was necessary to provisionally patent the device – official application number: 2003/6702.

Повний текст джерелаblades plays an important role in fan&rsquo
s efficiency. Therefore, selection of a fan and its pitch angle, which yields the maximum efficiency, is an emerging issue for an efficient mine ventilation. The main objective of this research study is to provide a decision making methodology for the selection of a main fan and its appropriate pitch angle for efficient mine ventilation. Nowadays, analytical hierarchy process as multi criteria decision making is used, and it yields outputs based on pairwise comparison. On the other hand, Fuzzy Logic as a soft computing method was combined with analytical hierarchy process and combined model did not yield appropriate results
because Fuzzy AHP increased uncertainty ratio in this study. However, fuzzy analytical hierarchy process might be inapplicable when it faces with vague and complex data set. Soft computing methods can be utilized for complicated situations. One of the soft computing methods is a Neuro-Fuzzy algorithm which is used in classification and DM issues. This study has two phases: i) selection of an appropriate fan using Analytical Hierarchy Process (AHP) and Fuzzy Analytical Hierarchy Process (Fuzzy AHP) and ii) selection of an appropriate pitch angle using Neuro-Fuzzy algorithm and Fuzzy AHP method. This study showed that AHP can be effectively utilized for main fan selection. It performs better than Fuzzy AHP because FAHP contains more expertise and makes problems more complex for evaluating. When FAHP and Neuro-Fuzzy is compared for pitch angle selection, both methodologies yielded the same results. Therefore, utilization of Neuro-Fuzzy in situation with complicated and vague data will be applicable.

Повний текст джерелаENGLISH ABSTRACT: In the 20th century, many employees in the South African mining industry were involved in occupational accidents which either resulted in personal injury or had fatal consequences. Despite the introduction of numerous industrial safety programmes to prevent fatal incidents and minor injuries, the South African mining industry death toll remains consistently high, at approximately 200 employees per annum. The trend of employee injury and death continues unabated into the new millennium. This safety performance has been met with growing dissatisfaction in the ranks of government, worker unions, employees and business stakeholders. This dissatisfaction is directed at chief executives who are being blamed for the occupational accidents on their mines. There is now growing focus on the leadership of mining companies and how it contributes to shaping an organisational culture for improved safety performance. The researcher examines whether leadership is a key component in creating a safety conscious organisational culture, and uses literature studies and the Anglo American mining company as a practical case study to support the investigation. Anglo American, listed on the Johannesburg and London stock exchanges is the largest mining company in South Africa and also one in which many fatal injuries have occurred; providing an abundance of safety information. The researcher reviews previous literature studies and explains the journey Anglo American undertook to improve its safety performance since listing on the London Stock Exchange in 1999. The concepts of organisational culture, safety culture, leadership and organisational performance, are discussed from a theoretical and practical perspective using literature studies. These are then examined with the ultimate view of understanding their practical impact on organisational safety as espoused in the literature. The literature provides a broad framework on which to assess Anglo American's safety journey from 1999 to the end of 2007. This journey details the safety programmes and efforts employed by Anglo American to eliminate fatalities and injuries and also highlights the impact of the organisation's leadership on the safety performance of the company. It is concluded that the contribution of leadership is pivotal to establishing a safety-conscious organisational culture and that specific behaviours from executives, senior managers, middle managers, supervisors and workers are needed to develop an organisations safety culture for improved safety performance.
AFRIKAANSE OPSOMMING: Gedurende die 20ste eeu was baie werkers in die Suid-Afrikaanse mynbedryf betrokke in beroepsverwante ongelukke wat tot persoonlike beserings of lewensverlies gelei het. Ten spyte van die instelling van veelvuldige beroeps-veiligheidsprogramme om noodlottige insidente en ander minder ernstige beserings te voorkom, bly die dodetal in die Suid-Afrikaanse mynbedryf konstant hoog, teen ongeveer 200 werkers per jaar. Hierdie tendens van dood en beserings onder werkers gaan ongetem voort tot in die nuwe millennium. Hierdie veiligheidsrekord word met toenemende ontevredenheid deur die regering, werkers-vakbonde, werkers en bedryfsinsethouers beskou. Hierdie ontevredenheid word gemik op uitvoerende bestuur, wie blameer word vir beroepsverwante ongelukke in hul myne. Daar word dus toenemend gefokus op die leierskap van mynmaatskappye en hoe dit bydra tot die skepping van 'n organisasiekultuur van verbeterde veiligheidsuitslae. Die navorser ondersoek die vraag of leierskap 'n kern komponent is in die daarstelling van 'n veiligheids-bewuste organisasiekultuur, en maak gebruik van literatuurstudies sowel as Anglo American mynmaatskappy as 'n praktiese gevallestudie om sy ondersoek te ondersteun. Anglo American is die grootste mynmaatskappy in Suid-Afrika en ook die een waar baie noodlottige ongelukke voorgekom het, en dus 'n groot bron van veiligheidsinligting kan voorsien. Die navorser hersien teoretiese literatuurstudies en verduidelik dan die optrede van Anglo American om sy veiligheidsrekords te verbeter sedert sy noteering op die Londonse Effektebeurs in 1999. Die konsep van organisasiekultuur, veiligheidskultuur, leierskap en organisasieprestasie, word bespreek vanuit 'n teoretiese en praktiese perspektief met behulp van literatuurstudies en hierdie word bestudeer met die uiteindelike doel om die praktiese impak daarvan in industrie te verstaan soos uiteengesit in die literatuur. Die literatuur voorsien 'n breë raamwerk waarteen Anglo American se veiligheidstog gemeet kan word vanaf 1999 tot einde 2007. Hierdie tog verskaf detail van hoe Anglo American veiligheidsprogramme gebruik het om noodlottigge ongelukke en beserings uit te skakel en beklemtoon ook die impak van die organisasie se leierskap op die veiligheidsrekord van die maatskappy. Die gevolgtrekking word gemaak dat die bydrae van leierskap kern is tot die daarstelling van 'n veiligheidsbewuste kultuur en dat spesifieke optredes van hoofbestuurders, seniorbestuurders, middelvlakbestuurders, opsieners en werkers nodig is om 'n veiligheidskultuur te bewerkstellig om veiligheid in maatskappye te verbeter.

We introduce some geometric experiments to the students, and particularly the handling of right-angled triangles, with the clear purpose of inserting, firming and emphasizing the importance, historical and practical, of the concept and meaning of the geometric tangent in an entire acute angle in triangle. Later, the students built a rudimentary theodolite that was used to measure vertical angles of tops inaccessible objects from the ground and consequently the estimate of their heights. The prospect objects were trees, poles, masts, antennas, spotlights, among other more familiar to the students of the ninth grade in elementary school.
Neste trabalho apresentamos aos alunos alguns experimentos geométricos e, sobretudo, a manipulação de triângulos retângulos, com o claro objetivo de inserir, fixar e ressaltar a importância, histórica e prática, do conceito e do significado geométrico da tangente de um ângulo agudo. Posteriormente, os alunos construíram um teodolito rudimentar que foi utilizado para medir ângulos verticais de topos de objetos inacessíveis em relação ao solo e consequentemente o cálculo de suas alturas. Os objetos explorados foram árvores, postes, mastros, antenas, refletores, entre outros mais familiares para os estudantes do nono ano do Ensino Fundamental.

Ballscrew is working as a driven device of machine tool to reinforce the manufacturing precision and smoothness. Nowadays, ballscrew is applied extensively in precision machinery, automation equipments, dynamic transmission, semi-conductors, medical treatment, aerospace, and etc; furthermore, ballscrew is developed to apply in superior precision, high speed, environmental protection, long travel and big diameter as well. Ballscrew functions as a power transfer interface between a screw shaft and a nut. Axial load which is depended on the contact angle of steel ball and screw is a major element to affect lifetime value of ballscrew. If contact angle exceeds the design value, steel ball will change its running pattern from rolling to sliding, which will cause the friction increased, bad smoothness, and temperature increased to reduce the lifetime value. Previously, the profile meter which provides high precision with superior using environment request is used for measuring contact angle. The digital projection method which integrates projectors, digital cameras, and image processing software is an efficiency and precision way to examine ballscrew. This method can achieve rapid online measurement and precision requirements for small lead angle through different contact angles measurements and comparing with the profile meter. It also can measure screw diameter over 50mm and length over 2500mm.

For establishing an accurate ellipsometer system in the laboratory, it is essential to calibrate each element of the system. A simple polarimetric technique is developed in this experiment to measure the optical axis and the phase retardation of a quarter-wave plate. By three intensities measured in PA (Polarizer-Analyzer) system with Analyzer at 0, 60, and 120 degree, and another three intensities measured in PCA (Polarizer Compensator-Analyzer) system with Analyzer at 0, 60, and 120 degree, we can calculate the azimuth angle and the phase retardation of the compensator. We find the compensator''s optical activity and its optical axis precisely when using the He-Ne Laser source first. Then we use a Tungsten-Halogen source which produces 632.8nm, 543.5nm, and 488nm light by three different filters to investigate the performances of this 632.8nm quarter-wave plate (compensator) under different wavelength of light.

Повний текст джерелаIntroduction: Musculoskeletal conditions of the foot/ankle are highly prevalent, both in normal and sports contexts. Physiotherapy is essential in their treatment, being the use of self-reported measurement instruments fundamental for proper evaluation of the impact of these conditions on the individuals, as well as the impact of the treatment. The Foot and Ankle Ability Measure (FAAM) is a self-reported measure of assessment of physical function in patients with musculoskeletal conditions of the foot/ankle, with two subscales, Activities of Daily Living and Sports. Aims: Cultural and linguistic adaptation, validation and evaluation of the responsiveness of the FAAM to the Portuguese population. Materials and Methods: The cultural and linguistic adaptation was achieved by the sequential methodology. For the evaluation of the psychometric properties, FAAM and VR-12 were administered to 179 individuals. The data collection was made in three stages: at T0, Test-Retest and T1 (end of treatment). Results: We obtained the FAAM-PT with semantic and cultural equivalence with the original version. This achieved high levels of internal consistency (αAVD=0.98; αDesporto=0.95) and reproducibility (ICCAVD=0.90; ICCDesporto=0.84). It demonstrated good construct validity through the Principal Component Analysis, the relations with the VR-12 summaries (r between 0,241 and 0,575) and related discriminatory questions (BMI, r between -0,212 and -0,290; and walking aids, p=0,000). It showed good reproducibility (ESAVD=0.78; ESDesporto=0.94; SRMAVD=0.87; SRMDesporto=1.00) and good interpretability (SEMAVD=3,14; SEMDesporto=5.60; MDCAVD=8,71; MDCDesporto=15.51; MICAVD=5.96; MICDesporto=19.06). Conclusions: FAAM-PT proved to be a valid, reliable and responsive measure for individuals with musculoskeletal conditions of the foot/ankle, it is recommended in research and in clinical practice.

One of the contributions of the economic development of Taiwan depends on high quality and high stability of the products. In order to maintain the high standard of the products, most companies have only focused on using the newest and finest equipments or establishing a more strict system for quality control. However, they neglected that they must have precision measure to keep the high standard. The industrial angle measures instrument has always been placed for “the preliminary set-up of machine or pre-running”. With the advance of operation technology and the introduction of all kinds of new machines, the instruments are more diversified, the precision is higher, the application is also more extensive, and thus the relative importance of this industry becomes higher. However, there has not been a proper strategy selection evaluation model or system to help the industrial angle measures instrument industry to improve the competitiveness. Besides, many new products have been introduced to the market and consumers with the fast progress of technology development. Enterprises must make innovation and improvement continuously in order to survive. Before promoting new products to the market, an enterprise should consider the difference between the old products and the new ones and also the competitiveness from other similar products. Therefore, to win the market, an enterprise must not only introduce the product’s merits, but must also develop a proper product strategy. From the above discussions of new products, strategy and the importance of their connection, we know that an appropriate strategy for a new product is a key for the successful development of the enterprise. This purpose of this research is to thoroughly study the industrial angle measures instrument and to suggest a strategy selection evaluation model via fuzzy multiple criteria decision making for enterprise application.

Carbon composes lots of material, like diamond and graphite. But the biggest difference is that graphite is a conductor while diamond is an insulator, because of the bonding. The carbon atoms in the diamond hybridize into the three-dimension sp3 covalent bonding, however the carbon atoms hybridize into two-dimension sp2 covalent bonding in-plane and the delocalized pz bonding results in metallic bonding which forms the π band. The interaction between layer and layer is the weak van der Waals' force so that graphite is a conductor. Graphite has been researched for decades. M. S. Dresselhaus和G. Dresselhaus used the tight-binding theory to describe the band structure of graphite in 1981 and A. Grüneis used the TB-GW to describe the band structure of graphite. In my thesis I will discuss the electronic structure of graphite measured by ARPES. Unlike graphene, graphite is a three-dimension material the different position along z ̂ direction, the different the band structure of graphite will be. To graphite, the two valence π bands with the different incident photon energy which respect to different position along z ̂ direction, results in the periodically merge or split of two valence π bands. In addition I will use the tight-bind theory to describe the Fermi surface result from two valence π bands. The major goal is obtain a set of tight-binding parameters that could well-described Fermi surface at high binding energy, moreover using the same parameters to describe the Fermi surface at low binding energy. Then discuss the describing at low binding energy.

Повний текст джерелаBackground: Iliotibial band friction syndrome is a common dysfunction seen in athletes. Athletes develop biomechanical changes yet still continue with their sport. However, this syndrome limits their ability to participate at peak performance. This study determined which participants benefitted in terms of biomechanical and clinical outcomes in one of four groups: ankle joint, superior tibio-fibular joint, sacroiliac joint or a combination manipulation group (which contained any two of the three joint restrictions). Methods: This Durban University of Technology Institutional Research and Ethics Committee approved prospective clinical trial, utilised stratified sampling, with 48 participants across four groups: ankle (14); superior tibio-fibular (11), sacroiliac (12) and combination (11). The participants underwent six treatments in three weeks. Data collection occurred before consultations one, three, five and seven. The data included primary measures of the knee score questionnaire (KSQ), the algometer, the visual analogue scale (VAS) and the secondary measures of the Feiss line, the heel leg alignment, bilateral leg length, Q angle and tibio-femoral angle. All data was computed utilising the ANOVA testing, with a p-value <0.05 being significant and a 95% confidence interval. Pearson’s correlations were completed for intragroup associations between primary and secondary outcome measures. Results: The intragroup analysis revealed that all groups had significant changes in the KSQ and VAS, with the exception of the sacroiliac joint manipulation group (KSQ outcome not significant). Intergroup analysis revealed no differences between the groups with the exception of the combination group, which showed a significant increase in the tibio-femoral angle. Most commonly, the Pearson’s correlation revealed that changes in leg length were related to differences in primary outcome measures, irrespective of the group being tested. Conclusion: The outcomes of this study indicated that manipulation of the distal kinematic chain improved alignment and clinical outcomes to a greater degree than manipulating proximal restrictions. It is suggested with caution (due to limited sample size) that patients should first have their distal kinematic chain manipulated before more proximal joints are manipulated to achieve better outcomes.

Повний текст джерелаObjective To assess the learning effect, test–retest reliability and measurement error associated with the SEBT. Design Repeated-measures study. Setting Controlled university laboratory environment. Participants Twenty-two healthy recreational athletes (11 male age 22.3 ± 3.7 years, 11 female age 22.8 ± 3.1 years). Main Outcome Measures Repeated-measures ANOVA assessed learning affects. Intraclass correlations coefficients, standard error of measurement and smallest detectable difference values were calculated to assess reliability and measurement error. Results Results showed that excursion distances stabilised after four trials, therefore trials five to seven were analysed for reliability. Test–retest reliability for all reach directions was high, with intraclass correlation coefficients ranging from 0.84 to 0.92. 95% confidence intervals, standard error of measurement and smallest detectable difference ranged from 77.84 to 94.00, 2.21–2.94% and 6.13–8.15%, respectively. Conclusion These statistics will allow clinicians to evaluate whether changes in SEBT scores are due to change in an individual’s performance or random error. The findings of this study show that the SEBT is a reliable measure of lower limb function in healthy recreational athletes. Changes in normalised scores of at least 6–8% are needed to feel confident that a real change in SEBT performance has occurred.

Повний текст джерелаThe preparation of this thesis examines, in principle,the concept of probability and its basic properties, such as the random variable and distribution function and presents data of basic discrete and continuous distributions, including normal, uniform, the Poisson, and other distributions of linear statistics. Then it refers to the basic concepts of descriptive statistics, such as the organization and the graphic representation of statistical data, grouping observations Frequency histogram as well as descriptive measures of linear data. Mostly, though, this study represents an overview of statistic methods of presentation and analysis of periodic data. By the term "periodic data" we mean random addresses and directions orientation. The presentation of random angles, graphic representations of periodic data and descriptive measures - measures of location, dispersion, skewness and kurtosis - will lead us to a better approach and understanding of periodic distributions. Furthermore, we present in detail the basic periodic distributions, the uniform and the Von Mises distribution. But other unimodal and multimodal distributions will be examined such as wrapped distributions, the cosine and cardioid distribution, skewed distributions, etc. Finally, this thesis will mention a family of symmetric periodic distributions proposed by Mr. Papakonstantinou and an extension of the cardioid distribution, according to the paper published by the scientists Toshihiro Abe,Arthur Pewsey and Kunio Shimizu, where significant advantages are provided over other families of distributions.
