Schnittstellensynthese: Modellierung - Optimierung - Codegenerierung

Behler, Christian, Defo, Bertrand, Kouamo Sime, Michel, Loke, Tobias 18 July 2006 (has links)
Diese Schriftenreihe präsentiert wissenschaftliche Arbeiten zum Entwurf und zur Selbstorganisation von eingebetteten Systemen. In dem ersten Band dieser Schriftenreihe liegt der Fokus auf der Konzeption von „Rekonfigurierbaren Schnittstellen“. Der vorliegende zweite Band stellt eine vollständige Methodik für die Adaptierung von inkompatiblen Schnittstellen in komplexen, verteilten, eingebetteten Systemen vor. Diese Methodik wird als Interface Synthese (IFS) bezeichnet. In den vier Beiträgen werden im Einzelnen die Modellierung, die Analyse und Optimierung sowie die Codegenerierung als methodische Entwurfsschritte untersucht. Der erste Beitrag behandelt die Modellierung von komplexen Kommunikationssystemen als ersten Schritt des Interface Synthesis Design Flows. Es wird ein UML2.0 Profil sowie dessen Transformation in das Synthesewerkzeug vorgestellt. Die zwei folgenden Beiträge befassen sich mit der Analyse und Optimierung der Schnittstellensynthese. Der erste Ansatz basiert auf der Optimierung der Ausführungspipeline, während der zweite Ansatz eine globale Optimierung durch partitionierendes Clustering in Verbindung mit benutzerspezifischen Protokollen anwendet. Der vierte Beitrag greift die Codegenerierung und somit den letzten Schritt des Interface Synthesis Design Flows auf. Es wird ein dedizierter VHDL-Codegenerator vorgestellt, der insbesondere die Rekonfigurierbarkeit der Schnittstelle unterstützt.

How can physical activity be enhanced through digital rewards? : An experiment where number of steps is rewarded with social media screen time

Tallberg, Marina January 2021 (has links)
Today nearly 9 in 10 internet users use social media each month. Most people enjoy social media and have a beneficiary relationship with the different platforms giving them opportunities to stay connected with family and friends. However, some people have a problematic relationship and can suffer consequences like anxiety, jealousy, depression and/or fear of missing out. As social media use has increased in in past twenty years, people have, during a longer period, become more and more sedentary. Digitalization is one of the reasons to why man has become less active. Television, computers, tablets and smartphones have content designed to make us spend as much time in front of them as possible. Physical activity during the day is important to maintain good health and counteract various types of wellbeing. A sedentary lifestyle can make people feel unhappy, anxious, stressed and in worst case lead to different types of life-threatening conditions. The purpose of this bachelor thesis is to identify how physical activity can be enhanced through digital rewards, from the perspective of people striving for a healthier lifestyle. An experiment was conducted to be able to answer the thesis research questions. The experiment consisted of a one-week test where participants got to take steps for social media screen time. Data and information were collected from the participants before the test week and after through surveys. The self-reported data and information from the surveys were after that analyzed and discussed. The result of the experiment cannot be considered valid due to the low number of participants. However, the results from the ones participating showed an increase in step count in almost all participants and a decrease in time spent on social media. The conclusion of the study indicates that social media screen time can be used as a digital reward to motivate physical activity. In addition, most participants reported being more aware of both social media screen time and their physical activity after the experiment.

Looking back to move forward, how would I embed greater participation throughout mydonor-funded multimedia impact series?

Ashleigh, Conor January 2020 (has links)
This degree project involves a self-reflective analysis of an Australian Centre forInternational Agricultural Research (ACIAR) funded multimedia series. I produced thework in 2017, about the impact achieved in an agricultural research for developmentproject, working with cattle farmers in Indonesia. The overarching purpose of this study isto examine how I would embed greater participation throughout my filmmaking process ifundertaken again. The work is published online and comprises of five short films whichare accompanied by a series of photographs and text story. I chose to examine apreviously completed project of my own, knowing that it was undertaken with a limitedCommunication for Development (ComDev) perspective that has since been developedthrough my Master’s degree at Malmo University. Through my research, I seek first toidentify what aspects of the previous filmmaking process were participatory; second,investigate if there is a filmmaking process that could be recommended for future use toensure a greater level of participation among people; and third, determine if my donorfundedmultimedia impact stories only serve the public relations outcomes of thedevelopment industry.

Influence des contraintes sur la reconstruction de l'Au (111) / Influence of stress on the Au(111) reconstruction

Chauraud, Dimitri 13 November 2019 (has links)
L’évolution de la reconstruction de surface de l’Au(111) sous contrainte-déformation a été étudiée dans le cadre d’une approche, à la fois expérimentale par microscopie à effet tunnel sous environnement ultra-vide couplée à un dispositif en compression, et numériquement par simulations en dynamique moléculaire. Dans un premier temps, nous avons étudié l’interaction entre les marches atomiques (vicinales ou traces de glissement) et la reconstruction. Nous avons notamment montré expérimentalement une forte dépendance de la longueur de la reconstruction avec la largeur des terrasses, en très bon accord avec les simulations atomistiques. Nous avons démontré de manière quantitative que ce comportement provenait de la relaxation des contraintes de surface, à la fois le long et perpendiculairement aux marches atomiques. Par la suite, nous avons montré que l’apparition d’une trace de glissement, résultant de l’émergence d’une dislocation à la surface, induit une réorganisation de la reconstruction, caractérisée par la formation d’un motif en forme de U. Nous avons par ailleurs observé expérimentalement la présence de décrochements le long de la trace. Les simulations ont confirmé que ces décrochements étaient corrélés avec la modification de la reconstruction. Dans un second temps, l’étude s’est axée sur l’évolution de la reconstruction en chevrons sous contrainte-déformation appliquée. Les observations expérimentales ont montré qu’une contrainte de compression macroscopique était à l’origine d’une modification de la structure en chevrons. Les simulations en dynamique moléculaire ont permis d’analyser l’influence de l’orientation de la contrainte sur les dislocations perçant la surface. Nous avons montré qu’une réorganisation irréversible de la structure en chevrons a lieu, se caractérisant par l’annihilation des dislocations perçant la surface et la suppression de la structure en chevrons. / The evolution of the surface reconstruction of the Au(111) under stress-strain has been studied in the context of an experimental approach, both by tunneling microscopy under ultra-vacuum environment coupled to a compression device, and numerically by molecular dynamics simulations. At first, we studied the interaction between atomic steps (vicinal or slip traces) and reconstruction. In particular, we showed experimentally a strong dependence of the length of the reconstruction with the width of the terraces, in very good agreement with the atomistic simulations. We have quantitatively demonstrated that this behavior is originated from the release of surface stress, both along and perpendicular to the atomic steps. Subsequently, we have shown that the appearance of a slip traces, resulting from the emergence of dislocations at the surface, induce a reorganization of the reconstruction, characterized by the formation of a U-shaped pattern. We also observed experimentally the presence of kinks along the trace. The simulations confirmed that these kinks are correlated with the modification of the reconstruction. At last, the study focused on the evolution of the chevron pattern under applied stress-strain. Experimental observations have shown that a macroscopic compressive strain involved a modification of the herringbone structure. Molecular dynamics simulations allowed to analyze the influence of stress orientation on surface threading dislocations. We have shown that an irreversible reorganisation of the herringbone structure takes place, characterized by the annihilation of the surface threading dislocations and the removal of the herringbone structure.

The Effect of Maternity Care Practices on the Duration of Breastfeeding

Rodriguez, Lisette 01 January 2019 (has links)
The natural practice of breastfeeding has been strongly noted as one of the most cost-effective, health promoting, disease-prevention strategies of the 21st century. Although primary health organizations recommend exclusive breastfeeding for the first 6 months of life with added complementary foods and continued breastfeeding up to 2 years of age or longer, many mothers do not breastfeed their infants for the recommendation length of time. Applied policies and health practices, such as those described under the 10 Steps to Successful Breastfeeding and The International Code of Marketing of Breast Milk Substitutes, have been noted as contributing factors that can considerably impact the manner which women choose to feed their infants. A cross-sectional methodology assessed associations between maternity health practices and breastfeeding duration among women birthing in the United States. A secondary data analysis of the Infant Feeding Practice Study II and its Year 6 Follow-Up was conducted using IBM SPSS Statistics Version 24. Procedures for data analysis included frequencies, Ï?2 tests, and ordinal logistic regressions. Outcomes revealed that feeding infants any formula during their hospital stay drastically reduces the likelihood for prolonged breastfeeding duration. Study results also concluded that offering a pacifier to infants during their hospital stay reduced the length of breastfeeding duration. This study confirms many of the primary breastfeeding practices that are at the frontline of maternity patient care in the United States. Establishing well-grounded practices that aid in the long-term duration of breastfeeding could help save lives and improve child and maternal health outcomes within the United States.

Pohybová aktivita dětí s motorickými obtížemi / Physical activity of children with motor difficulties

Kokštejn, Jakub January 2012 (has links)
Bibliographic identification Name and surname of the author: Mgr. Jakub Kokštejn Name of the dissertation: Physical activity of children with motor difficulties Workplace: Department of Sports Games Supervisor of the work: Doc. PaedDr. Rudolf Psotta, Ph.D. Year of presentation: 2011 Abstract Objective: Current knowledge of developmental disorders in motor skills of school children suggest potential negative impacts on the development of the personality of the child in the mental, social psychological and behavioural areas and also in the area of competence at school. Very little is known about how an insufficient level of motor skills of a child can limit his/her physical activity. This work was performed to discover whether developmentally determined motor deficit in children of older school age is a risk factor for lower physical activity (PA) and whether the attention of the child has a mediation function in the relationship between the level of motor skills and his/her physical activity. Methods: The research was based on analytical-descriptive examination of the motor skills of children, their physical activity in weekly regimes and the attention level, with subsequent comparison of children with a motor deficit (MD) and children without MD, through correlation analysis and analysis of the mediative...

The Correspondence between Receptive and Expressive Task Performances: A Further Analysis of Necessary Conditions

Nachawati, Noor 12 1900 (has links)
This study was a replication and an extension of the 2021 research performed by Spurgin and Borquez on the correspondence between receptive and expressive behavior. Spurgin examined the role of the echoic in a hear-say procedure with adult learners, while Borquez examined the role of the echoic in both hear-say and see-say procedures. Both studies found that receptive and expressive correspondence did not occur consistently across participants. The present study asked if the fading steps used during training contributed to the results of the previous researchers. In the present study, the fading steps were changed to minimize the chance that the participant developed a position bias. The conditions were also counterbalanced to analyze the effects of hear-say vs. see-say, easy vs. difficult words, and the order in which the words were trained on the acquisition of receptive labels and the emergence of expressive labels. The study consisted of five phases: pre-training, hear-say teaching, see-say teaching, receptive testing, and expressive testing. Results indicated that although that acquisition of receptive labels improved, the change in fading steps did not make a significant difference in the correspondence of receptive and expressive language. Results showed similar correspondence in the hear-say and see-say procedures. Easy words and words taught more recently were correlated with increased receptive-expressive correspondence.
