Qualitative simulation is a key inference technique of model-based reasoning and is successfully demonstrated in areas like monitoring, fault-diagnosis and design. For industrial applications, embedded qualitative simulation is required, i.e., the qualitative simulator is coupled with the physical process by a set of sensors and actuators. Often the qualitative simulator must additionally satis...

The step motor is a kind of electric actuator that transfers electrical pulses to angular displacement. How to fulfill the control task of step motor by embedded control system is a practical problem since the common computer control system has a higher cost and more redundant than the customized embedded control system. A dual-ARM7 microcontroller embedded structure is developed in this paper ...

Embedded computer control is increasingly common in appliances, vehicles, communication devices, medical instruments, and many other systems. Some embedded computer systems enable users to obtain their own programs from parties other than the maker of the device. For instance, PDAs and some cell phones offer an open application programming interface that enables users to better customize device...

Image processing and computer vision is being used in a variety of applications including applications in embedded devices (surveillance, quality control, traffic monitoring, etc.). In these applications, the data are used in real-time (in the traffic monitoring and decision-making sensors for example). Real-time video processing is computationally demanding, making microprocessor-based process...

Embedding ethics modules within computer science courses has become a popular response to the growing recognition that programs need better equip their students navigate ethical dimensions of computing technologies such as artificial intelligence, machine learning, and big data analytics. However, popularity this approach outpaced evidence its positive outcomes. To help close gap, empirical stu...

Model-based system development emphasizes the usage of models throughout the development process. In such an approach, modeling becomes of central importance, forming a basis for documentation, communication, decision-making, and design automation. As this design paradigm becomes gradually adopted for the development of embedded computer control applications, new modeling requirements become ap...

Research Laboratory for providing his graph scheduling simulator. This dissertation is dedicated to my family. They have been extremely supportive of me throughout my life. I would like to express my deepest gratitude to my wife, Minji Kim and my daughter, Evelyn Jiahn Lee. Finally I would like to appreciate my parents for their endless supports and love. Without their supports, I would not be ...

In the paper, we propose a scheme about a low-cost remote healthcare monitor system based on embedded server between home and hospital. In the scheme, we design an embedded server based on an ARM9 microprocessor. The embedded server supplies all kinds of interfaces such as GPIO interfaces, serial interfaces. These interfaces can acquire all kinds of physiology signals such as Electrocardiograph...

In Saudi Arabia, the Riyadh Sewage Treatment Plant (RSTP) uses the activated sludge technology as the secondary treatment process for sewage. Due to the complex nature of the process, a rather simplified, yet practical, steady state model that captures the most important features of the RSTP was developed. Actual operating and design conditions were obtained from RSTP data bank. The monthly ave...
