This paper introduces a practical analytical approximation of projectile trajectories in 2D and 3D roughly based on a linear drag\nmodel and explores a variety of different planning algorithms for these trajectories. Although the trajectories are only approximate,\nthey still capturemany of the characteristics of a real projectile in free fall under the influence of an invariant wind, gravitational pull,\nand terminal velocity, while the required math for these trajectories and planners is still simple enough to efficiently run on almost\nall modern hardware devices. Together, these properties make the proposed approach particularly useful for real-time applications\nwhere accuracy and performance need to be carefully balanced, such as in computer games....
Ecology plays a central role in biology and deserves special attention in scientific education. Nonetheless, the teaching and learning\nof ecology face a number of difficulties. In order to tackle these difficulties, electronic games have recently been used to mediate\necology learning. This paper presents an electronic game that fulfills these gaps in order to make the studentsââ?¬â?¢ work with ecological\nconcepts more concrete, active, and systematic. The paper presents the computational model of the ecological system included in\nthe game, based on a real ecological case, a sand dune ecosystem located in the semiarid Caatinga biome, namely, the sand dunes\nof the middle SÃ?Å?ao Francisco River, in the state of Bahia, Brazil. It includes various ecological relationships between endemic lizards\nand the physical environment, preys, predators, cospecifics, and plants.The engine of the game simulates the physical conditions\nof the ecosystem (dune topography and climate conditions with their circadian and circannual cycles), its biota (plant species\nand animal species), and ecological relationships (predator-prey encounters, cospecific relationships).We also present results from\none classroom study of a teaching sequence structured around Calangos, which showed positive outcomes regarding high school\nstudentsââ?¬â?¢ understanding of thermal regulation in ectothermic animals....
Theissue on neural network method to solve concave games is concerned. Combined with variational inequality, Ky Fan inequality,\nand projection equation, concave games are transformed into a neural network model. On the basis of the Lyapunov stable theory,\nsome stability results are also given. Finally, two classic games� simulation results are given to illustrate the theoretical results....
There is ample evidence that technology-enhanced instruction could result in students� learning. With the advancement\nand ever-increasing growth of technology, the use of educational electronic games or computer games in education has\nappealed to both educators and students. Because of their potential to enhance students� interest, motivation and\ncreativity, computer games can be used to teach various skills and strategies to different types of students, particularly\nschoolchildren. These games have also made inroads into language learning classrooms as they provide language\nlearners with a rich learning context to engage in authentic and meaningful learning experiences. This paper reviews the\npotential of integrating computer games into second/foreign language syllabi and curricula by offering a synopsis of the\nassumptions, prior studies and theoretical background in support of these games in language education. At the end, the\npaper touches upon the role of teachers and the likely inhibiting factors affecting the integration of computer games into\nEnglish language programs....
