Identifying the factors that affect the severity of vehicular crashes by driver age

Tollefson, John Dietrich 01 December 2016 (has links)
Vehicular crashes are the leading cause of death for young adult drivers, however, very little life course research focuses on drivers in their 20s. Moreover, most data analyses of crash data are limited to simple correlation and regression analysis. This thesis proposes a data-driven approach and usage of machine-learning techniques to further enhance the quality of analysis. We examine over 10 years of data from the Iowa Department of Transportation by transforming all the data into a format suitable for data analysis. From there, the ages of drivers present in the crash are discretized depending on the ages of drivers present for better analysis. In doing this, we hope to better discover the relationship between driver age and factors present in a given crash. We use machine learning algorithms to determine important attributes for each age group with the goal of improving predictivity of individual methods. The general format of this thesis follows a Knowledge Discovery workflow, preprocessing and transforming the data into a usable state, from which we perform data mining to discover results and produce knowledge. We hope to use this knowledge to improve the predictivity of different age groups of drivers with around 60 variables for most sets as well as 10 variables for some. We also explore future directions this data could be analyzed in.

Porovnání vlivu různých typů výustek na intenzitu přenosu tepla konvekcí z lidského těla / The influence of different types of ventilation outlets on the heat transfer by convection from the human body

Zábovský, Ján January 2020 (has links)
The aim of this diploma thesis is to investigate the influence of different types of HVAC system outlets on convective heat transfer from a human body. The first part of the thesis consists of an overview of essentials important for understanding the issue, specifically, metabolism, thermoregulation, heat transfer mechanisms, thermal vote and fluid dynamics. The second part defines the main working hypothesis and describes the used experimental approach leading either to confirmation or disproval of the hypothesis. The chosen approach is based on a measurement with thermal mannequin “Newton” using two different configurations: constant surface temperature and constant generated heat flux. In case of the first configuration, the convection intensity indicator was the value of heat flux generated from each of surface segments of the thermal mannequin. Their surface temperature was the indicator when running the experiment using the second configuration. The value was evaluated by the thermal mannequin as well as the thermal camera Flir i7 which provided more detailed division of the surface. The final part of the thesis describes the progress of the experiment itself, represents gathered values involving analysis of contaminants and confirms or disproves the original thesis.

Optimalizace zadní nápravy sportovního vozidla SIGMA / Rear Axle Optimization of SIGMA Sports Car

Repka, Martin January 2021 (has links)
This master’s thesis deals with analysis and following optimisation of a Sigma TN sports car suspension. Knowledge of vehicle dynamics and strength of materials was used during the optimisation. Kinematic and force analysis was carried out in software ADAMS Car. A FEM analysis was processed in Ansys Workbench environment. Three design concepts were worked out, in which Topology optimisation also found use.

Měření dosahu IEEE 802.15.4 / IEEE 802.15.4 range measurements

Komadel, Lukáš January 2009 (has links)
In the master’s thesis IEEE 802.15.4 Range measurements I want to find out, whether atmospheric conditions have influence over the quality of communication between two ZigBee modules. I would like found the answer by long-time test, because I can’t found the proper place for the measuring, I must found the answer in the literature. In the second part of the master’s thesis I measuring, whether placing one of the module in the car have influence over the quality of communication. The module was placing in the various places in the car, on a dashboard, on a guest-passenger’s seat, in a pocket before guest-passenger and in luggage compartment. The car for the measuring was used Renaul Scénic my. 2004.

Modelování prostředí v kabině osobního automobilu / Simulation of indoor environment in a car cabin

Tuka, Ján January 2011 (has links)
The thesis deals with the evaluation of indoor environment cab passenger car, with a focus on thermal comfort of passengers. The theoretical part contains the fundamentals of heat transfer, analysis of the aspects affecting human thermal comfort and its assessment methods. A brief description of the ventilation and air conditioning systems used in passenger cars is mentioned. The practical part includes numerical simulations of indoor environment, in selected driving modes and at different climatic conditions. Results of simulations lead to evaluation the status of the internal environment in terms of thermal comfort.
