The dynamics of many epidemiological models for infectious diseases that spread in the sexually active population presents a crucial period: the period of the influx or recruitment of susceptible. In this paper, we assume that the recruitment of susceptible is done among the juvenile group. We propose a dynamical system to modelize the disease spread, and we study the dynamical behavior of this...

Graphics processing units (GPU) have been intensively used by high-performance computing applications. However, GPU’s large power consumption is a big issue coexisting with the high parallelism. Although Dynamic Voltage and Frequency Scaling (DVFS) [1] has been heavily studied and successfully applied to real products for saving CPU power consumption, DVFS is still relatively new for GPU energy...

Introduction The most of objects in our real life has smooth shape. The subdivision meshes are developed for representing the characters and the objects naturally in animations and games. The subdivision meshes are methods of representing the smooth surfaces using iterative operation with a few number of data (control meshes). The graphics processing unit (GPU) in nowadays has more flexible str...

Energy efficiency has become one of the top design criteria for current computing systems. The dynamic voltage and frequency scaling (DVFS) has been widely adopted by laptop computers, servers, and mobile devices to conserve energy, while the GPU DVFS is still at a certain early age. This paper aims at exploring the impact of GPU DVFS on the application performance and power consumption, and fu...

Using the graphics processing unit (GPU) to accelerate general-purpose computations has become an important technique in scientific research. However, the development complexity is significantly higher than for CPU-based solutions, due to the mainly graphics-oriented concepts and development tools for GPU-programming. As a consequence, general-purpose computations on the GPU are mainly discusse...

Many embedded systems process huge amount of data that comes from the interaction with the environment. The Graphics Processing Unit (GPU) is a modern embedded solution that tackles the efficiency challenge when processing a lot of data. GPU may improve even more the system performance by allowing multiple activities to be executed in a parallel manner. In a complex component-based application,...
