configuration of urban land use arrangement system, how to divide and how to use urban lands are advantages of environmental, economic, social, politic and rightly forces. with extension of urbanization and development of urban and regional planning, this concept is more widely hold a special place in the form of projects such as: land preparation, framework planning, general and comprehensive,...

In the present study, field oriented control of step motor implementation has been analyzed sothat it can make a Sensorless control. Efficiency and Facilities of step motor is more than othertypes of electromotor. Therefore, the numbers of mechanisms and different types of turning canbe made into them. Also controlling these motors is easier than other available motors. Steppingmotor has been d...

Most of the basic research on the electrical behavior of CNTs has been carried out on individual or bundle nanotubes. More recently random or oriented CNT networks (CNTN) are emerging as new material for electronic application. We present the fabrication of thick and dense CNTNs, in the form of freestanding films, and the study of their electric resistance as a function of the temperature, from...

− Accurate knowledge of stator resistance is of utmost importance for correct operation of a number of speed sensorless induction motor control schemes in the low speed region. Since stator resistance inevitably varies with operating conditions, stable and accurate operation at near-zero speed requires an appropriate on-line identification algorithm for the stator resistance. The paper proposes...

one of the modern paradigms to develop an application is object oriented analysis and design. in this paradigm, there are several objects and each object plays some specific roles in applications. in an application, we must distinguish between procedural semantics and declarative semantics for their implementation in a specific programming language. for the procedural semantics, we can write a ...

appearance of nationalism in each country is influenced by some social , religious and political factors throughout the history of that country in iranian contemporary history, this process has also been dependent upon opinions and thoughts of some of the nationalist intellectuals and modernists their intellectual products played an important role in various social , intellectual and even artis...

the present study investigated the use of interactive metadiscourse resources (imrs) in terms of appropriacy during a process- based writing course by applying qualitative and exploratory methods. moreover, learners' perception was investigated to find out how confident they felt as they were writing and rewriting the drafts. 30 intermediate efl learners were chosen to participate in this study...
