Chládková, Karolína January 2017 (has links)
Title Impact of compensation exercises on forward shoulder posture in sport climbers Aims The aim is to decide whether in climbers regulary performing compensation excercises occurs lower rate of forward shoulder posture than in non-excercising climbers. Methods The diploma thesis is a pilot study of quantitative nature with participation of 48 probands. The probands were sports climbers, men and women aged 18-35 with no shoulder pain or disorder. The minimal requiered climbing level was determined to VII UIAA. The data were gained by caliper measure of two anatomical points; cranial part of sternum and anterior part of acromion, both in natural posture and upright posture. All measurements were one-off with the aim to gather the data that were consequently processed and statistically analyzed. Results The results confirmed that compensation exercises have impact on forward shoulder posture. The results did not confirm the same values of protraction on both shoulders.

Noggrannhet och precision vid beståndsuppskattning av mobilapplikationen KATAM / Accuracy and precision in stand measurements of the mobile application KATAM

Andersson, Erik January 2019 (has links)
Syftet med arbetet var att utvärdera mobilapplikationen KATAM avseende noggrannhet, tidsåtgång, precision och praktisk användning i jämförelse med volymuppskattning med dataklave och skördarrapport. Resultatet vid diameterjämförelsen visar på snarlika uppskattningar från KATAM respektive dataklaven. KATAM hade högre medelgrundyta, 7 % och grövre medeldiameter, 3,7 %, i jämförelse med dataklaven. KATAM hade även överskattningar av medelstammen volym i jämförelse med skördarrapporten och dataklaven, från 2,5 % till 17,6 % beroende på vilket urval av provytor och vilken programversion av KATAM som användes. Underlaget från volymuppskattningar var litet och hade felkällor vilket gjorde resultaten från mätningarna osäkra. Trots att studien visade på en överskattning av diametern talar den inbördes precisionen för att KATAM skulle kunna bli ett alternativ till Dataklaven vid uppskattning av medeldiametern. / The purpose of this essay was to evaluate the mobile application KATAM of accuracy, time, precision and practical use in comparison to volume estimation with data Digital Caliper and harvester report. The result of the diameter comparison showed similar estimates from KATAM and the Digital Caliper respectively. KATAM had a higher mean basel area, 7% and coarser mean diameter, 3.7%, compared to the Digital Caliper. KATAM also had overestimations in volume as compared to the harvesting report and the Digital Caliper concerning the mean stem, from 2.5% to 17.6%, depending on which sample areas were included and which version of KATAM was used. However, the basis of volume estimates was small and had error sources, which made the results of the measurements uncertain. Although the study shows an overestimation of the diameter, the mutual precision indicates that KATAM could be an alternative to the Digital Caliper when estimating the mean diameter.

Tais alunos estão, simultaneamente, matriculados em uma escola pública do ensino médio regular da Região Metropolitana do Recife. Nessas escolas, como se sabe, eles estudam as disciplinas Matemática e Física. Além disso, escolhemos focalizar nosso trabalho no ensino do uso do paquímetro, dispositivo amplamente utilizado nas medições de comprimento, no âmbito da indústria, dos serviços profissionais e nas ciências. O quadro teórico adotado é a transposição didática (Chevallard, 1991). A medição de comprimento requer a consideração de vários conceitos matemáticos, entre os quais o de número racional (a medida de comprimento) bem como o da incerteza do resultado dessa medição (o “erro de medida”). Optamos por investigar materiais didáticos disponíveis para os estudantes do citado curso, em particular duas apostilas de Metrologia e as coleções de Matemática de Física. Esses materiais foram analisados do ponto de vista de se constituírem um dos elementos que cumprem o papel de meios da transposição didática dos saberes em jogo. A análise dos dados obtidos revelou vários pontos em que o saber estabelecido no campo das grandezas e da medição de grandezas é abordado de modo inadequado, nos materiais didáticos examinados. Isso conduz à hipótese de que fica comprometida nesses materiais uma transposição didática que se apresente como um instrumento eficaz de aprendizagem dos estudantes. / The aim of this work was to investigate the teaching of length measurement for students Metrology course in a course of the National Technological Education Program - PRONATEC, under the Ministry of Education - MEC (BRAZIL, 2011). Such students are simultaneously enrolled in a public school in regular high school in the Metropolitan Region of Recife. In these schools, as we know, they study subjects Mathematics and Physics. In addition, we chose to focus our work in teaching the use of vernier caliper, widely used device for length measurements in the industry, professional services and science. The theoretical framework is the didactic transposition (Chevallard, 1991). The length measurement requires consideration of various mathematical concepts, including the rational number (gauge length) as well as the uncertainty of the result of measurement (the "measurement error"). We chose to investigate teaching materials available to students of that course, in particular two booklets Metrology and collections of Mathematical Physics. These materials were analyzed from the point of view of constituting one of the elements that play the role of means of didactic transposition of knowledge into play. The data analysis revealed several points where the established knowledge in the field of quantities and measured variables is addressed improperly in teaching materials examined. This leads to the hypothesis that is compromised in these materials a didactic transposition that is presented as an effective learning tool for students.

A Study of the Selling Strategy of the Metrology-- Case Study of Coordinate Measuring Machine

Chen, Cheng-Tung 16 August 2011 (has links)
ABSTRACT(­^ ¤å ºK ­n) The mother of the industrial machinery industry, often regarded as a national benchmark assessment of industrial competitiveness, the traditional concept of the cutting and forming machine tools for the spindle, including optoelectronics, semiconductors, automobiles, 3C electronics and aerospace industries, the relevant production or processing equipment, all belong to this category. With the evolution of technology, increasingly stringent product quality requirements, such as the appearance of the size of the high precision requirements and the material surface, gradually the importance of testing equipment and manufacturing go hand in hand, on behalf of the state's technology industry is expected in the near The future will be an important assessment of industrial competitiveness indicators. On the other hand, the mainland market after ten years of cross-strait exchange, itself played a significant change, from the early to the extreme dependence on imported equipment to produce the world-famous cottage products, no matter how the people of Taiwan to the mainland products exclusion, in the free under the natural law of market competition, the consumer market in Taiwan has long been filled with many mainland-made products. Their number and variety of the broad, deep penetration, simply makes hard to detect, and many exclusive products in the mainland business executives, the factory uses a lot of their own system of equipment are still unaware of the mainland, and even know, but also not find to alternative products. Indeed, many products have to meet the continent needs, these needs is not only reflected in the consumer goods market, is also rapidly spreading to the industrial market. Most of the countries with advanced manufacturing technology in the world, more or less with metrology industry. Taiwan alone will not only have no metrology manufacturing base, and even the Taiwan metrology companies in , mainland China, the increasing decline in ability to survive, the market that introduced by the Taiwan factories in the past swallowed gradually and easily by the local vendors. Worry about the future of Taiwan metrology industry. If Taiwan metrology industry can not get a good position in the world, can we be famous just by create a brand? Case is a company with more than 30 years of metrology sales background, in southern Taiwan. Because the relatively small market, it is difficult to obtain the dominant position of advantage. However, with the rise in the mainland market, the case company is full of many opportunities. This paper will research the sale strategy during these changeable situations. Bisides, metrology includes wide range products, this paper choose Coordinate Measuring Machines (CMM) as the basis of the primary products, mainly because of higher prices, the level of broader considerations in business, relatively high barriers to entry, in addition, it also has many features quite representative of the industry's products. Key words: Metrology, Coordinate Measuring Machines, CMM, hardness, surface roughness measuring instrument, roundness measuring instrument, the contour profile instrument, caliper, height gauge, optical flatness gauge, indicating scale, micrometer , microscopes , projectors , block gauge
