    Haptic device application in persian calligraphy

    , Article Proceedings - 2009 International Conference on Computer and Automation Engineering, ICCAE 2009, 8 March 2009 through 10 March 2009, Bangkok ; 2009 , Pages 160-164 ; 9780769535692 (ISBN) Mansouri Boroujeni, M ; Meghdari, A ; Sharif University of Technology
    The Haptic device is capable of interacting dynamically with the operator by the forces it can exert on human's hand. Controlling the haptic device and constraining it through the desired trajectory is the common task in the most of the training systems. Haptic interface application in virtual Persian handwriting learning system is investigated in this paper. Two different modes of learning is investigated: The full guidance mode, guides the user to follow a prerecorded trajectory by applying proper force to operator's hand; whereas in partial guidance, combination of haptics andvisual feedback guides the operator and prevents deviation from the desired trajectory. © 2009 IEEE  

    A 6-bit digital phase shifter by using HEMT technology

    , Article Proceedings - 2012 IEEE 8th International Colloquium on Signal Processing and Its Applications, CSPA 2012 ; 2012 , Pages 29-32 ; 9781467309615 (ISBN) Ameri, S. H ; Sabaghi, M ; Pourhossien, A ; Kouchaki, M ; Rahnama, M ; Sharif University of Technology
    A 6-bit passive phase shifter for S frequency band has been designed in a standard HEMT technology. A new switched-network topology has been proposed for implementing the 5.625 phase shift step which these digital bits are series with each other. We used Advanced Design System (ADS2010) to perform simulations. These digital bits will produce 64 different mode phase shift of -177.15 to +177.15 degree. In all cases simulation obtained less than 1 % error  

    A hybrid scatter search for the discrete time/resource trade-off problem in project scheduling

    , Article European Journal of Operational Research ; Volume 193, Issue 1 , 2009 , Pages 35-48 ; 03772217 (ISSN) Ranjbar, M ; De Reyck, B ; Kianfar, F ; Sharif University of Technology
    We develop a heuristic procedure for solving the discrete time/resource trade-off problem in the field of project scheduling. In this problem, a project contains activities interrelated by finish-start-type precedence constraints with a time lag of zero, which require one or more constrained renewable resources. Each activity has a specified work content and can be performed in different modes, i.e. with different durations and resource requirements, as long as the required work content is met. The objective is to schedule each activity in one of its modes in order to minimize the project makespan. We use a scatter search algorithm to tackle this problem, using path relinking methodology as...
