Next-generation multiprocessor real-time systems consume less energy at the cost of increased power density. This increase in power density results in high heat density and may affect the reliability and performance of real-time systems. Thus, incorporating maximum temperature constraints in scheduling of real-time task sets is an important challenge. This paper investigates a novel algorithm for...
Model-based approaches to the planning or control of robot locomotion or manipulation requires the solution of complementarity problems that model intermittent contact. Fixed-point iteration is a method of computing fixed points of functions and there are several fixed-point theorems to guarantee the existence of fixed points. With the help of proximal point functions, the complementarity problems...
In this paper, a pedaled, self-balanced, personal mobility vehicle named Legway, is developed. The vehicle is structurally similar to a pedaled unicycle but uses a brushless DC (BLDC) hub motor as its main driving wheel. For this one-wheel vehicle, it is intended that the unstable longitudinal dynamics is stabilized by a feedback control system but the lateral balancing and steering are manually controlled...
An experimental approach to the general gray model GMHN was adopted in this paper. Using the GM(0,N) model, we analyze the free vibrations of a Timoshenko beam-carrying multiple spring-mass system. The relative weighting between the five lowest natural frequencies generated by inputting the three variables k*, m* and ξ*. First, we used the data and experiments from past literature to derive...
Moving object tracking has received much interest in the field of computer vision due to the increasing need for automated video analysis. Particles Filter is a very promising object tracking method since it is suitable for non-linear and/or non-Gaussian applications. Most particle filter applies color information in target model which might fail in the presence of similar colored objects in the scene...
With growing cost of electricity, the power management (PM) of server clusters has become an important problem. However, most previous researchers only address the challenge in homogeneous environments. Considering the increasing popularity of heterogeneous systems, this paper proposes an efficient algorithm for PM of heterogeneous soft real-time clusters. It is built on simple but effective mathematical...
Liver diseases and liver cancer has been the top ten causes of death among ten leading causes of death in Taiwan and always in the top. Usually, in the general liver function examination, biochemical test is the most common and a test that show the most direct reflection of the body condition. The health subject can determine the further inspection according to the inspection results. Nevertheless,...
Ball mill pulverizing system in thermal power plant is one of the most important parameters of unit's security and economy, and must be controlled in certain range. But it has large inertia and lag, So traditional PID control can not satisfy the performance requirement. In view of this characteristic, Hybrid Fuzzy PID Control was introduced. The simulating results indicate the proposed control system...
Experts use natural language in the unstructured decision-making problems, when they are establishing weights by pairwise comparison. In this paper, attribute hierarchical model (AHM) is utilized to establish weights. And grey fuzzy number is introduced, which can fully express experts?? will and make experts?? scoring more scientific. Then a new grey fuzzy unstructured decision-making model is proposed...

Breast cancer is one of the most common cancers and a major cause for death among women. Current clinical treatments are generally divided into surgical treatment, chemical synthetic drug treatment and radiotherapy. However the cure rate of these methods is lower and the poisonous side effect is great. With the development of bio-electro-magnetic, the electromagnetic radiation is frequently used in...
