Challenges of Business Simulation Games — A New Approach of Teaching Business

Serious games are part of the new emerging world of education environment that is based on sophisticated technology with elements of entertainment. They have been seen as good supplements for supporting the learning processes due to their capability to increase visualisations and challenge the student creativity. They have the potential to significantly improve training and education activities and initiatives. As a part of serious computer games, business simulation games support training and learning focused on the management of economic processes. They have been proven to be useful in empowering and mediating learning business content. This chapter addresses the simulation business games used in the educational process by analysing selected popular games regarding their properties that are considered as important in the learning process. The first part presents a short introduction in the field of business games and the approach used in selection of the studied games. The next part provides a review of related articles and brief overview of the state of the art that has guided the selection of business simulation games to be analysed and assessed. The game parameters used in the assessment have been defined and described. The analysis and the assessment report are followed with brief concluding remarks

MAP Selection Algorithms Based on Future Movement Prediction Capability in Synthetic and Realistic Environment

Efficient mobility management involves micromobility principles. The performance of the Hierarchical Mobile IPv6 (HMIPv6) protocol, a representative micro-mobility approach, is affected by the Mobility Anchor Point (MAP) selection. In this paper, we propose a new selection method based on a prediction of the future movements of Mobile Nodes (MNs). The proposed algorithms exploit the information about the future availability of MAPs and choose those MAPs that assure a better service. An improvement to the evaluation methodology is also proposed. The algorithms are compared to each other not only in synthetic but also in realistic internet topologies, which has not been a practice in the past. The simulation results show promising improvements in terms of distance from chosen MAPs and frequency of MAP changes. Moreover, we showed that, for perceivable improvement of MAP selection, absolute accuracy of movement prediction is not required. As pioneers in the mobility management analysis in realistic environment, we ascertain that offering MAP services over more than one Autonomous System (AS) proves beneficial

Metoda konačnih elemenata; teorija i praktična implementacija

Metoda konačnih elemenata je jedna od najpopularnijih numeričkih metoda za rješavanje parcijalnih diferencijalnih jednadžbi. Cilj ovog rada je na jednostavan način, kroz primjere, prezentirati metodu konačnih elemenata

Dekompozicija matrice na singularne vrijednosti

U ovom radu se daje primjer kako razviti i ubrzati sustav prepoznavanja rukom pisanih brojeva metodama računarskog vida. Dvije su komponente prezentiranog algoritma bitne. Smanjenje dimenzije problema i uklanjanje neželjene varijacije u snimljenim rukom pisanim brojevima. Način rada algoritma je prezentiran na primjeru kolekcije rukom pisanih brojeva koju je skupila američka poštanska služba. Ovaj primjer je poznat kao teški ogledni primjer za klasifikaciju podataka

Application of Linear and Nonlinear Heat Equation in Digital Image Processing

Istraživat ćemo primjenu parcijalnih diferencijalih jednadžbi u obradi digitalne slike. Primjenjujemo jednadžbu provođenja topline kako bismo na slici uklonili šum, istaknuli važne elemente i pripremili je za eventualnu daljnju obradu. Metodičkim slijedom dajemo teorijske značajke linearne difuzije, a zatim izvodimo jednostavne numeričke sheme temeljene na metodi konačnih razlika. Vođeni idejom očuvanja struktura na slici, primjerice rubova, u središnjem dijelu članka uvodimo Perona-Malikovu jednadžbu kao primjer nelinearne jednadžbe provođenja topline. Završavamo s usporedbom primjene linearne i nelinearne jednadžbe provođenja topline na testnim slikama.We will explore the application of partial differential equations on digital images. We will show how to use the heat equation to eliminate noise in an image, highlight important elements and prepare it for possible further processing. We also show known heat equation’s theoretical results in a methodical sequence and then derive simple numerical schemes based on the finite differences method. Guided by the idea of image structure preservation, for example edge preservation, the central part of this article introduces Perona-Malik equation as an example of a nonlinear heat equation. We conclude by comparing linear and nonlinear heat equation application on a couple of test images
