This paper describes dynamic system identification, and full control of a cost-effective vertical take-off and landing (VTOL) multi-rotor micro-aerial vehicle (MAV) — DJI Matrice 100. The dynamics of the vehicle and autopilot controllers are identified using only a built-in IMU and utilized to design a subsequent model predictive controller (MPC). Experimental results for the control performanc...

This paper considers the problem of generating optimal guidance trajectories for high-speed waypoint transitions by an autonomous helicopter. Given a set of waypoints and a desired order for passing through them, an optimal control problem is solved using collocation for every pair of consecutive waypoints. The linear hover model of the Yamaha R-50 helicopter is employed in the optimal control ...

during a study on fauna of the frit flies (diptera: chloropidae) in khorasan razavi province (iran) in 2014 and 2015, nine species of six genera were collected and identified. platycephala rugosa (nartshuk, 1964) is recorded for the first time for iranian fauna. geographical distribution and biological notes are provided.

leishmaniasis has long been known as a significant public health challenge in many parts of iran. phlebotomus pa­patasi and p. sergent i are the vectors of zoonotic cutaneous leishmaniasis and anthroponotic cutaneous leish­maniasis respectively, and 5 species of sand flies including p. kandelakii , p. neglectus , p. perfiliewi , p. keshishiani and p. alexandri are considered as probable vectors...

background: cutaneous leishmaniasis (cl) is endemic in many parts of iran. this study was conducted to investigate the fauna and some biologic factors of sand flies and detect cl vector(s) in kharameh district which is one of the most important foci of the disease in fars province, southern iran.   methods: to identify the fauna, a total of 1549 sand flies were collected from april 2014 to marc...

Recent developments of the aerodynamics models for the comprehensive analysis CAMRAD II are described, particularly the unsteady aerodynamic models and dynamic stall models, and the free wake geometry calculation. Three models for the unsteady aerodynamic loads in attached flow are implemented: from incompressible thin-airfoil theory, from ONERA EDLIN, and from Leishman-Beddoes. Five dynamic st...

Fixed-wing unmanned aerial vehicles (UAVs) with the ability to hover have significant potential for applications in urban or other constrained environments where the combination of fast speed, endurance, and stable hovering flight can provide strategic advantages. This paper discusses the use of dynamic inversion with neural network adaptation to provide an adaptive controller capable of transi...

In this paper, hierarchical control of an UAV (unmanned aerial vehicle) is proposed. The proposed controller is made up of two sub-systems, namely inner-loop controller and outer-loop controller. The inner-loop controller is an attitude control system while the outer-loop control system is a trajectory control system. In the proposed architecture, a DFNN-(dynamic-fuzzy-neural-network-) based re...

the paper contains the first report on the biology of snail-killing flies (sciomyzidae) in khuzestan. it is based on field and laboratory studies conducted during november 1971 and april 1973, as well as field observations in may 1972, at the dezful medical research station. additional biological information obtained during studies is given for pherbellia fuscipes (macaquart), p.grisescens (mei...

following annual report of new cases of cutaneous leishmaniasis from different areas of kuhpayeh district, esfahan county, an investigation was carried out on some ecological aspects of phlebotomine sand flies during 2000-2002. sand flies were collected biweekly from outdoor and indoor resting places with the aid of 30 sticky traps from the be ginning to the end of the active season. female san...
