Given a closed surface Sg of genus g, a mapping class f in \MCG(Sg) is said to be pseudo-Anosov if it preserves a pair of transverse measured foliations such that one is expanding and the other one is contracting by a number \lambda(f). The number \lambda(f) is called a stretch factor (or dilatation) of f. Thurston showed that a stretch factor is an algebraic integer with degree bounded above by 6g-6. However, little is known about which degrees occur. Using train tracks on surfaces, we explicitly construct pseudo-Anosov maps on Sg with orientable foliations whose stretch factor \lambda has algebraic degree 2g. Moreover, the stretch factor \lambda is a special algebraic number, called Salem number. Using this result, we show that there is a pseudo-Anosov map whose stretch factor has algebraic degree d, for each positive even integer d such that d≤g. Our examples also give a new approach to a conjecture of Penner.

Although formative assessment is fundamental to educational theory and practices, it is a widely misunderstood term for most educators. This qualitative study defines formative assessment as short-cycle assessments in which teachers adapt their instruction to meet the learners‟ immediate needs. This study focused on the transformation of teachers‟ practices and their perspectives of the critical pedagogical principles necessary to enact The Keeping Learning on Track Program® (KLT™) in their classrooms and in teacher learning communities. The participants in this study included 21 formally trained KLT teachers at the St. Johnsbury School. Over a one year period, I observed in classrooms, attended all KLT teacher learning community (TLC) sessions, collected field notes, attended KLT trainings and presentations, and conducted individual and focus group interviews. The primary area of transformation included: the regulation of learning, beliefs and attitudes, accountability, shared leadership, systemic supports, motivation, classroom culture, and teacher practices.

This thesis is about risk management in fast-track construction projects. The aim of the study is to identify the risks in the UAE construction industry, understand how they are dealt with, and propose more effective frameworks for risk management in fast-track construction. A mixed method approach was used to fulfil the objectives of the study. 65 questionnaires were distributed to professionals in the construction industry, including contractors, sub-contractors, project managers and private consultants. Their responses were analysed using statistical techniques, and the results taken for discussion to a focus group of eleven experienced construction managers and experts. Secondary data was also collected via literature reviews of print and website articles, and of books and documents from company, government and industry-specific databases. The findings show that risks in construction projects can be internal or external, and that in the UAE, owner- and design-related risks are seen as the most significant. Knowledge about risk management is present, but more needs to be done to eradicate the problems associated with poorly managed fast-track construction projects. Using the suggestion of the focus group, a framework for risk mitigation was developed based on the Alien Eyes’ risk and Qualitative Risk Management models. The study discusses the implications of risk management for practitioners and academicians in the construction industry. Poor risk management, which is usually the consequence of inadequate recognition of and/or responsiveness to risks and uncertainties, can have a devastating impact upon projects. It is hoped that practitioners applying the findings and suggestions in this study will see positive change, improved profitability and greater competitive advantage as a result.

Master of Science / Department of Architectural Engineering and Construction Science / Bill Zhang / Vibration has been a consideration in many types of structures, and as the advancement of technology has allowed steel and concrete sections to become lighter, vibration has become more of a consideration in the design of structures. This report focuses on occupant induced vibration of steel framed floors due to running as the vibration source. The history of vibration analysis and criteria in structures is discussed. However, lack of research and experimentation on running as the source of vibration exists; therefore, the history section focuses on walking as the source of vibration. The current design criteria for vibration of steel framed floors in the United States of America is the American Institute of Steel Construction (AISC) Design Guide 11: Vibrations of Steel Framed Structural Systems Due to Human Activity. This design guide discusses vibration due to walking, running, and rhythmic activities as well as gives design criteria for sensitive occupancies and sensitive equipment. In order to apply the Design Guide 11 analysis procedure for running as the source of vibration, the Kansas State University Chester E. Peters Recreation Complex is used as a case study. The recreation complex includes a 1/5-mile running track that is supported by a composite steel framed floor. Based on the Design Guide 11 criterion, the running track is deemed acceptable. Lastly, this report discusses remedial procedures in the case of annoying floor vibration specific to floors that have running as a source of vibration. In addition, areas of further research are suggested where running is a source of vibration on steel framed floors.

Title: The effect of stretching on performance of youth athletes in track and field Objectives: The difference of views on stretching as part of sports training is great, so this work aims to prove or disprove its effect on performance. The work should contribute to the awareness of domestic athletic trainers and the results will be applied practically. This work also aims to demonstrate whether the rate of shortened muscles affects the pupil's speed and endurance performance. The work is also interested in whether a strictly adhered stretching plan will reduce the amount of shortened muscles. Method: The thesis is conceived as an experimental study. The study was attended by 30 probands who were divided into two groups. To evaluate the results, a standardized test of shortened muscles according to Janda is used, as well as a run measured by hand-held stems for 2x40 and 600 meters. Result: There are great differences in the youth age between individuals with the almost same age and do the same sport. There are individuals who do not have shortened muscles, but those who have shortened almost every muscle group. The rate of shortened muscle does not affect pupil performance in athletics. Performance on the sprinter and endurance track was deteriorated or even improved, regardless of whether there...

Det här examensarbetet genomfördes sommaren 2017 på Autoliv Test Center i Vårgårda. Autoliv är världens ledande leverantör av säkerhetsutrustning och utvecklare av säkerhetssystem för fordonsindustrin. Autoliv genomför även krockprovning för kunder som vill genomföra tester av deras bilar före produktion. Vid krockprovning accelereras testfordonet av en krockprovningstrolley som kopplar samman fordonet med en vajer vilket drivs genom ett hydrauliskt framdrivningssystem. Trolleyn är en stålkonstruktion som är placerad i krockspåret vilket griper fast i stålvajern med ett klämsystem. Krockprovningsindustrin är i ständig utveckling med nya säkerhetssystem, hårdare regler och tuffare krav från myndigheter och fordonssäkerhetsorganisationer. Ett nyligen introducerat test kallat NHTSA Oblique 90km/h hade svårt att genomföras på grund av att klämmekanismen slirat vid genomförandet. Målet med examensarbetet har varit att ta fram en ny krockprovningstrolley som fungerar när den genomför NHTSA Oblique 90km/h. Arbetet har varit inriktat på att designa en trolley som fungerar under nuvarande förhållanden utan att göra inverkningar på krockbanan eller framdrivningssystemet. Fyra koncept har designats i 3D, utvärderas i en konceptmatris, diskuterats med erfaren personal och ett koncept valdes ut för fortsatt utveckling. Effekterna av den nya designen på komponenter har undersökts och justeringar genomfördes. En FEM-analys gjordes på det vinnande konceptet för att bedöma hållfastheten på trolleyn samt potentialen för viktoptimering. Resultat var en ny trolleyplatta, 20 cm längre och 10mm tunnare. Den ursprungliga plattans vikt bevarades och designen rekommenderades av personal på ATC. Trolleyn diskuterades och ytterligare rekommendationer gavs. / This thesis was performed in the summer of 2017 at Autoliv Test Center in Vårgårda. Autoliv is the world’s leading automotive safety supplier and developer of safety equipment for the vehicle industry. Autoliv also performs crash testing for customers wanting their concept cars tested before production. In crash testing, the vehicle is accelerated by a crash track trolley that connects the vehicle to a steel wire driven with a hydraulic propulsion system. The trolley is a steel construction positioned inside the crash track gripping the wire with a clamping mechanism. The crash testing industry is in constant development due to new safety systems, harder regulations and tougher requirements from governments and vehicle safety organizations. A recently introduced crash test called the NHTSA Oblique 90km/h had issues being performed due to slip between the clamping system and steel wire. The goal of this thesis has been to develop a new crash track trolley that does not malfunction during crash testing. The work has been aimed at designing a trolley that functions at current conditions without implications on the crash track or propulsion system. Four concepts have been designed in 3D, evaluated in a concept matrix, discussed with senior staff and one concept was chosen for further development. The effects of the new design on components have been investigated and adjustments were made. A FEM-analysis was done on the winning concept to look into the physical integrity of the new trolley as well as the potentials in weight optimization. The result was a new trolley plate, elongated by 20 cm and thinned by 10 mm. The same plate weight was preserved and the trolley design was recommended by senior staff at ATC. The trolley was discussed and further recommendations were given.
