Měření dopadu dokumentárních filmů na postoje a chování diváků / Measuring the impact of documentaries on the attitudes and behaviors of viewers

Půlpánová, Petra January 2017 (has links)
The thesis deals with measuring impact of documentary films on attitudes and behavior of the audience. The theoretical basis of this thesis is the assumption that social impact is a dynamic process where the engagement of an individual can lead to change of attitudes and behavior, and the individual's influence on others can change the society. Another assumption is that the impact on an individual is influenced by emotional and rational involvement. The third assumption is that the impact on the viewer changes over time when the extent of short-term impact after seeing the movie is bigger than extent of the impact measured with delay. The analytical part is devoted to the application of the method of repeated questioning, which allows to capture the development of the impact on the viewer over time. Within this thesis, a secondary analysis of quantitative data gathered in research of impact of films on ecological topic screened in film festival One World has been conducted. In addition, a thematic analysis of the in-depth interviews was conducted. These interviews have been carried out in order to establish the reasons and ways in which films impact the viewers. The conclusion of this thesis is that differences can be observed between the short and long-term impact on viewers in specific areas of...

A new helmet testing method to assess potential damages in the Brain and the head due to rotational energy

Carnevale Lon, Sergio Christian January 2014 (has links)
Preservation and protection of the head segment is of upmost importance due to the criticality of the functions entailed in this section of the body by the brain and the nervous system. Numerous events in daily life situations such as transportation and sports pose threats of injuries that may end or change a person’s life. In the European Union, statistics report that almost 4.2 million of road users are injured non-fatally, out of which 18% is represented by motorcyclist and 40% by cyclists, being head injuries 34% for bicyclists, and 24% for two-wheeled motor vehicles. Not only vehicles, are a source of injuries for the human head according to the injury report, 6,1 million people are admitted in hospitals for sports related injuries, where sports such as hockey, swimming, cycling presented head injuries up to 28%, 25% and 16% respectively (European Association for Injury Prevention and Safety Promotion, 2013).  According to records the vast majority of head crashes result in an oblique impact (Thibault & Gennarelli, 1985). These types of impacts are characterized for involving a rotation of the head segment which is correlated with serious head injuries. Even though there is plenty of evidence suggesting the involvement of rotational forces current helmet development standards and regulations fail to recognize their importance and account only for translational impact tests. This thesis contains an evaluation for a different developed method for testing oblique impacts. In consequence a new test rig was constructed with basis on a guided free fall of a helmeted dummy head striking an oblique (angled) anvil which will induce rotation. The results obtained are intended to be subjected to a comparison with another oblique test rig that performs experiments utilizing a movable sliding plate which when impacted induces the rotation of a dropped helmeted dummy head. The outcome will solidify the presence of rotational forces at head-anvil impact and offer an alternative testing method. After setting up the new test rig; experiments were conducted utilizing bicycle helmets varying the velocities before impact from 5m/s to 6m/s crashing an angled anvil of 45°. Results showed higher peak resultant values for rotational accelerations and rotational velocities in the new test rig compared to the movable plate impact test, indicating that depending on the impact situation the “Normal Force” has a direct effect on the rotational components. On the other hand a performed finite element analysis predicted that the best correlation between both methods is when the new angled anvil impact test is submitted to crashes with a velocity before impact of 6 m/s at 45° and the movable sliding impact test to a resultant velocity vector of 7,6m/s with an angle of 30° . In conclusion the new test method is meant to provide a comparison between two different test rigs that will undoubtedly have a part in the analysis for helmet and head safety improvements.

Effektivisering av arbetsmetod vid framtagning av detaljritningar för produktion och montage inom byggbranschen

Abid, Usman, Mustafa, Ghadir January 2021 (has links)
STARKA Betongelement AB är ett privatägt företag med fokus på att tillverka prefabricerade betongelement. STARKA jobbar allt från projektering, tillverkning och montering av betongelement. Den process som framförallt studeras är deras projekteringsprocess, här planeras de olika elementen som ska tillverkas samt monteras. För tillverkningen samt montagen framställs ritningar som underlag för detta arbete, dessa ritningar består av detaljritningar. Framställningen av dessa detaljeringar är i dagsläget en tidskrävande process, därav är syftet av arbetet att kunna utveckla en effektivare arbetsmetod som kan både underlätta för konstruktörer samt minska den krävande arbetstiden. Under arbetet följs Design thinking processen som metod vid framtagning av lösningskonceptet. Metoden består av fyra grundläggande faser, med start att skapa förståelse för det problem som antagits. Vidare studeras området kring de problemet, genom olika litteraturstudier, observationer, intervjuer samt olika tester. Efter att ha format en bra grund, skapas olika idéer för hur problemet ska lösas. Slutligen implementeras det slutliga lösningskonceptet på verksamheten samt utvärderas. Resultat består av ett AutoLISP-program som samlar alla nödvändiga funktioner under ett program, för framtagning av detaljritningar till produktionen. De funktioner som förekommer i programmet är följande: måttsättning av detaljer, godsmåttsättning, snittlinje, armeringstext samt hitsymbol. Funktioner och dess specifikationer som används i programmet har identifierats genom intervjuer och observationer med konstruktörerna på STARKA. För montageritningar har två olika lösningar utvecklats, där den första angriper problemet som konstruktörer har vid framtagning av komplicerade detaljer. Detta uppnås genom att utnyttja konstruktionens 3D-modell för att generera de eftersträvade detaljritningar. Den andra lösningen har sitt fokus på att generalisera olika standarddetaljer samt eliminera överflödig information, så som yttermått. Detta skapar i sin tur en bättre förutsättning för fler generella detaljer som kan återanvändas i nya ritningar för att bespara arbetstid. Som slutsats för produktionsritningar, underlättas arbetet genom att programmet samlar alla nödvändiga funktioner. Eftersom funktionerna har sina förinsatta specifikationer, uppstår inget behov att konfigurera de i efterhand och insättningen blir korrekt från första steget. Konstruktörerna har funnit lösningen hjälpsam samt har förenklat deras arbete genom att effektivisera handpåläggning och korta ned arbetstid. Gällande montageritningar, anses användningen av 3D-modeller vara väldigt krävande för datorer, men ett bra hjälpmedel vid komplicerade detaljer. För de vanliga detaljerna underlättar det att kunna använda generaliserade standarddetaljer för att slippa skapa och redigera nya till varje projekt. / STARKA Betongelement AB is a privately owned company with a focus on manufacturing prefabricated concrete elements. STARKA works with everything from design, manufacturing to the assembly of concrete elements. The process that is mainly studied is their design process, here the different elements are planned to be manufactured and assembled. For the manufacture and assembly, drawings are produced as a basis for this work, these drawings consist of detailed drawings. The creation of these details is currently a time-consuming process; hence, this study aims to develop a more efficient working method that can both make it easier for designers and reduce demanding working hours. During the work, the design thinking process is followed as a method when developing the solution. The method consists of four primary phases, starting with understanding the problem that has been given. Furthermore, the area of the problem is studied, through various literature studies, observations, interviews and various tests. After forming a good foundation, different ideas are created to solve the problem. Finally, the final solution is implemented at the company and the implementation was evaluated. Results consist of an AutoLISP-program that consists of all the necessary functions under one program, to create the detailed drawings for production. The functions that appear in the program are as follows: measurement of details, in-cast goods measurement, cut line, reinforcement text and “hitsymbol”. Features and their specifications used in the program have been identified through interviews and observations with the engineers at STARKA. For assembly drawings, two different solutions have been developed, the first of which tackles engineers' problems in creating complicated details. This is achieved by utilizing the construction’s 3D-model to create the desired detailed drawings. The second solution focuses on generalizing different standard parts and eliminating excess information, such as external dimensions. This in turn creates a better prerequisite for more general details that can be reused in new drawings to save working time. s a conclusion for production drawings, the work is facilitated by the program consist of all the necessary functions. Since the features have their pre-inserted specifications, there is no need to configure them afterwards and the insertion becomes correct from the first step. The designers have found the solution helpful and have simplified their work by making “handpåläggning” more efficient and reducing working hours. “Handpåläggning” consist of the functions and methods that the engineers at STARKA use to finalize the drawings. Regarding assembly drawings, the use of 3D-models is considered to be very demanding on computers, but good assistance in complicated details. The standard details make it easier to use standard generalized details to avoid creating and editing new ones for each project.

Experimentální studium teploty elektronů a iontů v impaktovém plazmatu / Experimental study of electron and ion temperatures in impact plasmas

Kočiščák, Samuel January 2021 (has links)
Title: Experimental study of electron and ion temperatures in impact plasmas Author: Samuel Kočiščák Department: Department of Surface and Plasma Science - DSPS Supervisor: doc. RNDr. Jiří Pavlů, Ph.D., DSPS Abstract: In-situ analysis of a hypervelocity grain impact is a complex discipline, making use of multiple physical phenomena. An important one, if not the most important one, being a dust impact ionisation. Future experiments could benefit substantially from better understanding of the phenomenon. The goal of this work was a study of the impact ionisation per-se, with the objective: to experimentally determine the effective temperatures of post-impact charged ejecta. Importance of this parameter is obvious, although different approaches scarcely ever report similar results. Our way was the analysis in a retarding potential analyzer. Firstly, large data set of laboratory data from dust accelerator was analyzed, secondly a Monte Carlo study of the results and the analyzer itself was performed. Lastly, recommendations for future in-situ experiments are provided based on our results. Keywords: impact plasmas cosmic dust impact ionization

Impacts territoriaux des événements sportifs parisiens (2013-2016) : l’approche par les dynamiques locales / Territorial impacts of sports event in Paris (2013-2016) : a local dynamics approach

Bourbillères, Hugo 26 September 2017 (has links)
Résumé : Depuis les années 1990, l’essentiel des travaux scientifiques sur l’impact des événements sportifs s’est focalisé sur les impacts économiques. Mais, depuis, quelques années, les effets immatériels relatifs à la dimension sociale sont de plus en plus étudiés. Dans ce contexte, la thèse porte sur la compréhension des impacts des événements sportifs récurrents sur le territoire parisien. À partir d’un recensement extensif, ce travail analyse 9 études de cas représentatives de la diversité observée des événements sportifs parisiens. La collecte de données s’appuie sur des séquences d’observation in situ (11), des entretiens semi-directifs (41) et de l’analyse documentaire. Fondée sur la théorie ancrée, posture qui part du terrain pour générer un cadre théorique, l’analyse montre que la compréhension des enjeux locaux ne peut se faire que par une contextualisation précise des situations locales et des volontés politiques.Ce cheminement inductif ouvre sur deux volets analytiques. Le premier construit une analyse des jeux d'acteurs qui révèle la centralité de l’acteur public dans les processus de mise en réseau. Le second éclaire la relation immatérielle qui s'organise entre l'événement et son territoire hôte, à travers la notion d'ancrage territorial. Ces développements conduisent à la proposition d’un « modèle des dynamiques locales », qui ambitionne d’appréhender tout ce qui se joue autour de l’événement sportif : ce qui lui permet d’émerger, autant que ce qu’il génère. En conclusion, considérant la fonction déterminante de l’acteur public dans l’événementiel sportif parisien, une approche plus globale est envisagée où l’agrégation des dynamiques locales pourrait se muer en une dynamique territoriale, initiée par un portefeuille d’événements sportifs complémentaires. / Since the 90s, scientific works on the impact of sports events has been mainly focusing on economics. However, for some years now, intangible effects related to social dimension of these events are increasingly studied. In this context, this work aims to understand the impacts of recurring sports events based in Paris. Started from an extensive census, this work analyzes 9 case studies representative of the observed diversity of sporting events in Paris. Data collection is based on in situ observations (11), semi-directives interviews (41), and documentary analyses. Based on grounded theory which uses a fieldwork approach to yield a theoretical framework, the analysis demonstrates that the understanding of local stakes can only be achieved through a precise contextualization of local situations and political willingness.This inductive pathway launches two analytical determinations: (1) to build a way to analyze interplays of actors that reveal the centrality of the public entity in the networking process (2) to highlight the intangible relationship between the event and its host territory, through the concept of “territorial anchorage.” These developments lead to the proposal of a “model of the local dynamics”. This model aim to apprehend all that revolves around the sporting event: from what allows it to emerge to what it generates. In conclusion, regarding the decisive role of the public entity within Parisian’s sporting events, a more global approach is envisaged where the aggregation of local dynamics could evolve into a territorial dynamic, beginning with a portfolio of complementary sports events.
