Deformačně napěťová analýza proximálního konce tibie s totální endoprotézou / Strain stress analysis of proximal tibia end with replacementTekalová, Soňa January 2010 (has links)
This thesis deals with stress analysis strain proximal end of tibia with total joint replacements. The analysis is done on the basis of deformation characteristics of voltage, through the finite element method (FEM). We have developed two-dimensional models of the proximal end of tibia with tibial components total endoprosthesis (TEP), without loss and bone loss. Geometry model is created based on data obtained from computerized tomography, which were further processed in the program, Rhinoceros 3.0 and SolidWorks 2009th Computational solution was carried out by finite element method in Ansys Workbench 12.0. The model without loss of bone tissue was tested the hypothesis that the deformation is very small and there is no violation of the shank prosthesis. Due to loss of bone tissue is lost support to the tibial pulse in the proximal tibia and by a progressive increase in stress, which can lead to a breach of the shank total joint replacement. The analysis results show that, if the loss of bone tissue, so that the tibial part of the TEP will lose support, there is a crack stem total hip replacement due to stress.

A Lifestyle Modification Toolkit to Increase Physical Activity Among Young AdultsNwanna, Anthonia Ninikanwa 01 January 2019 (has links)
Substantial decreases in physical activity have been observed between early to late adolescence in males and females, with decreases in levels of activity into adulthood. Physical inactivity among young adults leads to medical conditions such as Type 2 diabetes, stroke, ischemic heart disease, falls resulting in hip fractures, and depression later in life. Advanced Nurse Practitioners have a significant impact on the problem of physical inactivity among young adults through education to improve knowledge regarding physical activity participation. The focus of this project was to develop a toolkit on lifestyle modification as a resource for physical education teachers and nurses to increase physical activity participation and to decrease sedentary behaviors among young adults. The project practice question asked whether an evidence-based toolkit would address the identified needs of improving lifestyle diet and physical activity in young adults. Pender’s health promotion model guided the planning and development of the project. The Computer Attitude Questionnaire together with the 3-Day Physical Activity Recall was used during a needs assessment. Feedback from the survey was included in the development of the toolkit. A 5-item survey was given to 5 content experts who evaluated the toolkit. Data were analyzed using descriptive statistics to obtain a content validity index score of 1.00. Findings show universal agreement about the content of the toolkit as a resource for physical education teachers and school nurses to encourage physical activity participation in young adults. The implications of project findings for positive social change include the potential to increase the involvement of young adults in activities that improve the lives of the individual.

Kalkylerade kostnader ställda mot verkligt utfall för infraprojekt : Analys och uppföljning av infraprojekt / Calculated costs pledged against the actual outcome for infra projects : Analysis and follow up of infra projectsJansson, Daniel, Gelotte, Marcus January 2015 (has links)
Infrastrukturella projekt har ofta kalkylavvikelser, vilket har varit huvudanledningen till inriktningen för detta examensarbete. Rapporten beskriver mot en teoretisk referensram, kostnadskalkylering vid olika skeden i byggprocessen. Det redogörs hur kalkyleringen förändras och blir mer detaljerad i takt med att fler faktorer om det aktuella projektet efterhand blir kända. I rapporten läggs viss tyngdpunkt på uppföljningar av fyra stycken infraprojekt som kalkylerats hos Bygganalys på ÅF-Infrastructure AB. Kalkylerna har gjorts på uppdrag av beställaren Stockholms stad trafikkontor. Kostnadsuppskattningarna har ställts mot respektive entreprenörs anbudskalkyl/prissatta mängdförteckning för att identifiera vilka kostnadsposter som bidrar till kalkylavvikelser för de fyra projekten. Det redovisas även en uppföljning av den uppskattade ÄTA-summan som gjorts av Bygganalys för projekten, vilket ställts mot den verkliga ÄTA-summan. I uppföljningen av ÄTA-posterna har det även gjorts en identifikation av vilka avvikelser som orsakats av projekteringsfel och vilka som berott på ändrad arbetsomfattning eller kvalitetshöjande arbeten. I rapporten förekommer även slutsatser om orsaker till avvikelserna i kostnadsuppskattningarna och en redogörelse om vad avvikelserna kan bero på. / Infrastructural projects do often have calculated deviations, which has been the main reason to the selected orientation for this exam report. The report describes against a theoretical framework, cost accounting at different stages in the building process and how the calculations change and get more detailed as more factors about the current project gradually becomes known. The point of balance in the report is put on follow-ups of four infraprojects that has been calculated on Bygganalys at ÅF-infrastructure AB in request of the client Stockholm city traffic office. The calculations have been set against each entrepreneurs tender document/priced amount list to identify which costing post that contributes to the calculated deviation for the four projects. It also describes a follow-up of the estimated changed, additional and outgoing work sum that has been made by Bygganalys for the projects, which has been pledged against the actual outcome for changed, additional and outgoing work sum. In the follow-up of changed, additional and outgoing work posts it has also been made an identification of which deviations that has been caused by project planning failures and which that has been caused by changes in the amount of work or quality improvements.

Atributos en la realidad aumentada y su relación con la intención de compra aplicado en las plataformas virtuales de maquillaje en las mujeresAlvaro Rodrigo, Astudillo Moscoso, Ochoa Lister, Francisco Guillermo 03 December 2020 (has links)
El siguiente trabajo de investigación tiene como objetivo identificar cuáles son los atributos en la realidad aumentada y encontrar la relación que estas tienen con la intención de compra aplicado en las plataformas virtuales de maquillaje en las mujeres. Para realizar el objetivo se empleará un análisis cuantitativo con una ejecución de 384 encuestas a las consumidoras de Lima Metropolitana. Por medio del uso de herramientas como la escala de Likert se investiga el grado de efecto de cada una de las variables tiene con respecto a la intención de compra. Las variables identificadas que se consideraron más relevantes son los atributos hedónicos, utilitarios y de calidad de aumento percibida. Se ha encontrado que la relación que estos atributos tienen en los consumidores repercute emocionalmente en su estado de ánimo dependiendo del atributo. En el cual, la intención de compra se puede ver afectada por las distintas percepciones que el consumidor pueda tener en su proceso de compra. Dentro de los alcances y limitaciones encontradas para la investigación se consideraron la reducción del mercado y actividad económica, las cuales limitaron el número de acciones de marketing e intercambios y demanda de la población. Esto es debido al confinamiento causado por el COVID-19 desde el 16 de marzo del 2020 en donde se suspendieron todo tipo de actividades. / The following research work aims to identify which are the attributes in augmented reality and find the relationship that these have with the purchase intention applied in virtual makeup platforms in women. To carry out the objective, a quantitative analysis will be used with an execution of 384 surveys to the consumers of Metropolitan Lima. Through the use of tools such as the Likert scale, the degree of effect of each of the variables with respect to purchase intention is investigated. The variables identified that were considered most relevant are the hedonic, utilitarian and perceived quality of increased attributes. It has been found that the relationship that these attributes have on consumers emotionally affects their mood depending on the attribute. In which, the purchase intention can be affected by the different perceptions that the consumer may have in their purchase process. Within the scope and limitations found for the research, the reduction of the market and economic activity were considered, which limited the number of marketing actions and exchanges and demand of the population. This is due to the confinement caused by COVID-19 since March 16, 2020 where all kinds of activities were suspended. / Trabajo de investigación
