A fast convergent optimization algorithm is proposed in this paper to calculate sequential optimal trajectories for pursuing a moving target or under dynamically changing environments. The changing boundary conditions or perturbations in such problems require an efficient algorithm to update the optimal trajectories with appropriate time steps. Concepts of a uniform B-spline and differentially ...
Global adoption of IPv6 requires the provision of a scalable support for multi-homed sites. This article proposes a multi-homing solution based on the usage of the currently available MIPv6 protocol. It is shown that the MIPv6 protocol is suitable to be used for the provision of IPv6 multi-homing support without modifications in the packet formats defined in the specification, and that it only ...
In Air Traffic Control (ATC), controller workload has been an important topic of research. Many studies have been conducted in the past to uncover the art of evaluating workload. Many of which have been centered on the sector complexity or task demand based studies [1,2,3,4]. Moreover, all have the aim to understand the workload that was imposed on the controller and the extent to which the wor...
The rapid growth of WiFi over the past two years reveals the willingness of the Wireless Internet Service Providers (WISPs) to develop this technology and the interest of the users in this new service. However, the lack of unified roaming slows down the deployment of this kind of networks. In this paper, we present a simple solution that allows a mobile node to connect to a hot spot managed by ...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...
in this study, the effects of forming method (extrusion) and environmental factors (solution ph and temperature) on the corrosion performance of az91 magnesium alloys were investigated using potentiodynamic polarization, electrochemical impedance spectroscopy (eis), scanning electron microscopy (sem) and salt spray techniques. the polarization test results of the specimens showed that simple sh...
Today agriculture has to deal with an increasing cost pressure. Innovative Field-Robot-Based solutions can help to handle this challenge. Until now, such systems are not profitable and technically mature for commercial use. In the project AgriApps these issues are addressed. An application based system is developed where a carrier platform can be equipped with different apps. This allows the us...
A computational technique for solution of mathematical model of gas solution in a fluid is presented. This model describes the change of mass of the gas volume due to diffusion through the contact surface. An appropriate representation of the solution based on the M"{u}ntz polynomials reduces its numerical treatment to the solution of a linear system of algebraic equations. Numerical exa...
مهندسان در طراحی های بزرگ و پیچیده، قبل از ساخت نمونه فیزیکی و برآورد هزینه و زمان ساخت آن احتیاج به شبیه سازی کامپیوتری سخت افزار دارند. از طرفی سرعت شبیه سازهای متداول برای حجم بزرگ مدار بسیار کند می شود و این به دلیل محاسبات زیادی است که برای بدست آوردن اطلاعات ریز زمانی مدار انجام می شود. اما در بسیاری از موارد یک طراح احتیاج به دیدن درستی عملکرد طرح خود دارد و نه اطلاعات ریز زمانی آن. در ا...
