Model based fault diagnosis of fuel cells requires the development of a highly accurate system model. However, Fuel cell systems are considered to be very complex systems that are very difficult to model. Moreover, confidentiality issues with the manufacturer can sometimes impose constraints on the development of the model. This paper presents an approach to develop an accurate proton exchange membrane...
The increasing cost in power consumption in data centers, and the corresponding environmental threats have raised a growing demand in energy-efficient computing. Despite its importance, little work was done on introducing models to manage the consumption efficiently. With the growing use of Cloud Computing, this issue becomes very crucial. In a Cloud Computing, the services run in a data center on...
People's extensive and ignorant lifestyles impose an increasing amount of destruction on the environment, which lead to an increased governmental and research interest towards the development and use of green technology such as fuel cells. Fuel cells are recently receiving a major share of research interest due to their promising features. This paper presents an offline parameter identification approach...
Fuel Cells received a major research interest in the past few years. However, despite their promising features, Fuel Cell systems still lack a solid fault diagnosis and predictive maintenance study. There are numerous faults that have to be detected and diagnosed on a fuel cell power generator system, ranging from chemical faults, to electrical and power electronics faults. Several fault diagnosis...
The world's awareness towards the amount of destruction that our extensive and ignorant lifestyles in the past few decades have imposed on the environment is growing day after day. This resulted in an increased governmental and research interest towards the development and use of green technology. Fuel cells (FC) are one of the green technologies that received a major share of research interest in...
High quality transformer oil is required to increase the reliability and the life time of the transformer. This oil carries information about the operating condition of the transformer. Therefore, the transformer oil properties should be monitored in order to give early warnings and maintain the transformers efficiency. When the oil quality is decreased, it should be either changed or regenerated...
Global wind electricity-generating capacity increased by 28.7 percent in 2008 to 120,798 Gigawatts. This represents a twelve-fold increase from a decade ago, when world wind-generating capacity stood at less than 5 GW [1]. With wind becoming a key part of the electrical mix in Denmark (20% with 3.1 GW), Spain (8% with 10 GW), and Germany (6% with 18.4 GW), wind turbine reliability is having a bigger...
RoboCup is a worldwide competition designed to advance robotics and Artificial Intelligence research through a friendly competition. In this paper, sub-system flow analysis based on the robo-soccer competition requirements is detailed. The robot kinematics equations for planar motion in the X-Y plane are presented. Because the motors can operate individually or in groups, Broida's method was not good...
