Computer simulation was used to evaluate four selection strategies for reproductive success in beef cattle. The strategies were no culling; culling of nonpregnant heifers; culling of nonpregnant heifers and cows nonpregnant twice; culling all nonpregnant females. In addition, simulations were conducted utilizing method four for 20 yr, then changed to method three for an additional 20 yr. Cows w...
Human and livestock diseases can be difficult to control where infection persists in wildlife populations. In Britain, European badgers (Meles meles) are implicated in transmitting Mycobacterium bovis, the causative agent of bovine tuberculosis (TB), to cattle. Badger culling has therefore been a component of British TB control policy for many years. However, large-scale field trials have recen...
This paper explores the benefits that can be achieved for stereoscopic visualization when using occlusion culling strategies. Graphics processing units (GPUs) are improving their computational power and functionalities. On the other hand, models are also increasing their size and users require more demanding image quality. Occlusion culling provides significant frame rate speed-ups in densely o...
The characteristics of a livestock area, including farm density and animal species, influence the spread of foot-and-mouth disease (FMD). In this study, the impact of livestock area on FMD epidemics was examined using an FMD transmission model. For this simulation, three major livestock areas were selected: the 2010 FMD epidemic area in Japan as the baseline area (BS), a cattle and pig mixed pr...
nimating geometry procedurally, using a dynamical system (which consists of a set of state variables and a set of equations for describing how those variables change over time) rather than with keyframes, offers the advantages of physical realism , interactivity, compact descriptions, and infinite variety of motion. However, the use of dynamical systems has been inhibited by two factors: their ...
In this paper, we propose a novel 2D plenoptic function called “acentric panorama view (APV).” This novel 2D plenoptic function samples the panorama scenes without oversampling or undersampling. A single APV can be accelerated by view culling and list-priority rendering algorithm. Multiple APVs with special fields of view, 45◦, 60◦, 90◦, and 120◦, can be integrated into a larger configuration c...
