Storyworld, gesamtkunstwerk, art ecology: creating narrative geographies in the metaverse
No full textThis paper will bring together two terms originating from disciplines that at first glance may seem to be unrelated to artistic activity in Virtual Environments or Virtual Worlds: ‘Storyworld’ which is largely grounded in the field of Narratology, and Gesamtkunstwerk’ from the field of Aesthetics. These terms will be used as the theoretical framework that explicates on the creation of virtual, three dimensional ‘art ecologies’ for narrative purposes in virtual worlds. One such art ecology, created by the author, will be used as an example as to how such a narrative space has been built
Trends in the Development of Basic Computer Education at Universities
No full textBasic computer education in universities is experiencing huge problems. On the one hand, the amount of knowledge that a university graduate must have is increasing very quickly. On the other hand, the contingent of students varies greatly in terms of the level of training and motivation, and the level of this differentiation is constantly growing. As a result, the complexity of training and the percentage of dropouts increase. Scientists and educators are looking for a solution to these problems in the following areas: revising the knowledge necessary for obtaining at the university in the direction of the reality of their receipt in the allotted time; the use of new information technologies to simplify the learning process and improve its quality; development of the latest teaching methods that take into account the realities. This paper presents a strategic document in the field of computer education at universities - Computing Circulum 2020, as well as an overview of the areas of development of basic computer education, such as learning using artificial intelligence, virtual laboratories, microprocessor kits and robotics, WEB - systems for distance and blended learning, mobile application development, visual programming, gamification, computer architecture & organization, programming languages, learning technologies. In addition, the author gives his experience and vision of teaching basic computer education at universities
The Development of a Genetic Programming Method for Kinematic Robot Calibration
No full textKinematic robot calibration is the key requirement for the successful application of offline programming to industrial robotics. To compensate for inaccurate robot tool positioning, offline generated poses need to be corrected using a calibrated kinematic model, leading the robot to the desired poses. Conventional robot calibration techniques are heavily reliant upon numerical optimisation methods for model parameter estimation. However, the non-linearities of the kinematic equations, inappropriate model parameterisations with possible parameter discontinuities or redundancies, typically result in badly conditioned parameter identification. Research in kinematic robot calibration has therefore mainly focused on finding robot models and appropriate accommodated numerical methods to increase the accuracy of these models. This thesis presents an alternative approach to conventional kinematic robot calibration and develops a new inverse static kinematic calibration method based on the recent genetic programming paradigm. In this method the process of robot calibration is fully automated by applying symbolic model regression to model synthesis (structure and parameters) without involving iterative numerical methods for parameter identification, thus avoiding their drawbacks such as local convergence, numerical instability and parameter discontinuities. The approach developed in this work is focused on the evolutionary design and implementation of computer programs that model all error effects in particular non-geometric effects such as gear transmission errors, which considerably affect the overall positional accuracy of a robot. Genetic programming is employed to account for these effects and to induce joint correction models used to compensate for positional errors. The potential of this portable method is demonstrated in calibration experiments carried out on an industrial robot. Acknowledgements I am not going to thank anybody- because I did it all myself.

Sex differences in the developmental origins of cardiometabolic disease following exposure to maternal obesity and gestational diabetes.
No full textOver the last 30 years, the worldwide prevalence of obesity has nearly doubled. In addition, more and more women in their child bearing years are overweight or obese, which increases the risk for gestational diabetes mellitus (GDM). It is increasingly accepted by the scientific community that the early life exposure to environmental stress influences the long-term health of an individual, which has been termed the Developmental Origins of Health and Disease (DOHaD) theory. Evidence from human cohorts, epidemiological and animal studies have reported that maternal obesity and GDM alter the epigenome of the next generation, conditioning the offspring for cardiometabolic disease development. These effects are most likely regulated by epigenetic mechanisms; however, biological sex is an important factor in defining risk for the development of several metabolic health disorders. The aim of this review is to describe current evidence from human cohort and animal model studies that implicates sex differences in the developmental origins of cardiometabolic disease following exposure to maternal obesity and GDM. Additionally, this review will address the potential mechanisms involved in these sex differences. In many studies, sex is ignored as an important variable in disease development; however, the results presented in this review highlight important differences between sexes in the developmental programming of biological responses to exposures during the fetal stage. This knowledge will ultimately help for the development of effective therapeutic strategies for the treatment of cardiometabolic diseases that exhibit sexual dimorphism.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
