physical activity is connected with adults’ health in many ways, and walking is the most popular form of physical activity among adults all over the world. the authors have previously studied this issue in an under-construction environment in a new town in a developing country. the present study investigates the impact of built environmental features and qualities on walkability in developed ar...

The contribution of this paper to the space transportation system field is to select promising Reusable Launch Vehicle (RLV) concepts by using a formal evaluation procedure. The vehicle system is divided into design features. Every design feature can have alternative characteristics. All combinations of design features and characteristics are compared pairwise with each other. The innovation an...

45 0272-1708/04/$20.00©2004IEEE IEEE Control Systems Magazine T he World Wide Web has provided an opportunity for design and analysis of control systems through the Internet. An increasing number of Web-based software packages have been developed to enhance the teaching and design of control systems [1]. Today, one of the most popular applications in control systems is Web-based educational env...

the use of micro-controllers in actuators provides extended flexibility for on-line data acquisition and sophisticated control implementation. however, attempts to utilize the excellent features of induction motor that is deemed by its strength, robustness, high torque, and relatively low cost in actuators face a fundamental control design challenge. the purpose of this paper is to introduce th...
