Walnut Anthracnose is among the major diseases of walnut trees in Qazvin Province which is scattered as an epidemic disease in the recent years. This research is designed to study and comparison of control methods of Anthracnose disease in walnut trees of Roodbar region. After selecting the infected garden and implementing winter and spring spraying treatments, winter spraying treatment and con...

2 Summary The postural adaptation impairments of patients with Parkinson's disease (PD) suggest that the basal ganglia may be important for quickly modifying muscle activation patterns when the direction of perturbation or stance conditions suddenly change. It is unknown whether their particular instability to backward postural perturbations is due to specific abnormalities of parkinsonian post...

This paper presents a total system to register multiple range images to obtain complete object shape in the case where their relative viewing positions are unknown. To determine the relative position of. each viewpoint with respect to a common world coordinate system, the correspondences of the object's planar faces are used. For non-polyhedral objects, we produce a three dimensional convex hul...

parameter identification techniques are particularly attractive to determine the inertial parameters of robot manipulators and manipulated payloads. these parameters are particularly needed in implementation of a model-based controller for robot manipulators. in this paper, the inertial parameters of a manipulated rigid-body object have been estimated. the newton-euler equations will be employe...

Computerized Tomography (CT) is a standard method for obtaining internal structure of objects from their projection images. While CT reconstruction requires the knowledge of the imaging directions, there are some situations in which the imaging directions are unknown, for example, when imaging a moving object. It is therefore desirable to design a reconstruction method from projection images ta...

While CT reconstruction requires the knowledge of the imaging directions, there are some situations in which the imaging directions are unknown, for example, when imaging a moving object.

In this chapter, we consider three of the main problems that arise in the navigation of autonomous vehicles in partially or totally unknown environments, i.e. building a map of the environment, self-localizing, and servoing the robot so as to achieve given goals based on sensorial information. As compared to most part of the existing literature on SLAM, we privilege here a system-theoretic view...

In this paper, we focus on the use of knowledge bases in two different application areas – control of systems with unknown or strongly nonlinear models (i.e. hardly controllable by the classical methods), and robot motion planning in eight directions. The first one deals with fuzzy logic and the paper presents approaches for setting and aggregating the rules of a knowledge base. Te second one i...

an asymptotically stable direct adaptive fuzzy pi sliding modecontroller is proposed for a class of nonlinear uncertain systems. in contrast toother existing approaches of handling disturbances, the proposed approachdoes not require this bound to be known, only requiring that it exists.moreover, a pi control structure is used to attenuate chattering. the approachis applied to stabilize an open-...
