In this paper, a virtual lab based on MATLAB and FlightGear flight simulator is discussed and developed. The virtual lab consists of number of experiments that enhances the understanding of fundamental concepts of classical control for undergraduate students. The objective of the virtual lab is to design a stability augmentation system for C310 aircraft model according to known flying qualities then implement a hold autopilot for the aircraft. This objective is achieved through a series of experiments, animation and simulation to illustrate main concepts of classical control like modeling, time domain analysis, frequency domain Analysis, non-minimum phase systems, root locus, feedback design and PID compensation. These concepts are demonstrated in four experiments through the analysis and design of a flight control system for Cessna 310 aircraft on FlightGear flight simulator. The developed virtual lab can be used easily by students to study and visualize classical control principles using FlightGear and MATLAB GUI with an attractive case study of a flight control system.

Urban sprawl is an observed remarkable phenomenon within a city's structure. It translates its behavior of urban growth through creating newly developed areas to fulfill the increasing urban demands of its inhabitants. Although urban sprawl happens in all rural and urban settlements, it is essential to trace this phenomenon in the secondary cities as they consider transitional zones for various activities between the rural settlements and primate cities. Therefore, the research attempts to trace this phenomenon inside the secondary Egyptian cities through a deductive approach to locally state this phenomenon and deal with it according to the intermediate role of these cities. Firstly, the research defines the phenomenon of urban sprawl and its reasons by detecting a group of pillars that generally affect its occurrence. Subsequently, it moves to secondary Egyptian cities and compares, globally and locally, the appearance of these pillars. Finally, the research frames features of concurrence and conflict between the global and local appearance of reasons for urban sprawl in the secondary Egyptian cities. Subsequently, it figures the learned lessons from its comparison-based review for the reasons for urban sprawl by proposing a road map that can help in mitigating this phenomenon within the secondary Egyptian cities.

In 1996, the OECD coined the term knowledge city. This caused several developed countries to seek developing and adapting the features of their cities to be upgraded to knowledge-based economic cities. Hence, various experts worked on demonstrating and identifying the features of this concept. An objective of these cities was drawn: providing sound conditions for the enhancing, creation, and exchange of knowledge and innovation. The concept was found to be interdisciplinary: economic, political, social, as well as being urban and architectural. So, this chapter aims to observe the urban and architectural potentials of these cities, as well as their comparative importance. The comparative importance of these potentials is deduced through the study and analysis of some recognized KC models. Finally, a number of indices contributing to assessing the performance of such potentials are deduced.
