Shape optimization problem for semilinear elliptic equation is considered. there is an optimal solution which is computed by the Levelset method. To this end the shape derivative of the functional is evaluated. In order to predict the topology changes the topological derivative is employed. Numerical results confirm that the proposed framework for numerical solution of shape optimization problems is efficient.

In this paper, the translational accuracy performance of two algorithms that allow the pose of an Unmanned Aerial Vehicle (UAV) to be estimated is reported, based on preliminary data. the two algorithms are the 2D Homography and the 3D Iterative Closest Point (ICP) algorithm. Performance is measured against real image data taken with a digital Nikon D70 camera, with lens set at 3 different focal lengths. It is shown that best accuracy is achieved withthe 3D Iterative Closest Point algorithm and that focal length itself has little or no bearing on this performance. Calibration errors may impact accuracy.

this paper proposes a navigation system for mobile robot working in indoor environment, which includes mapping and trajectory generation for the motion tracking problem of the real mobile robot. the mapping process comprises a Gaussian model to improve the accuracy of the environment representation. Withthis new mapping method, the mobile robot knows the obstacle in the environment around robot itself. For the trajectory generation process, a multimodality method is used to explore all feasible paths to reach the target point by estimating the density of distribution of the objective function. Finally, the experiments show the effectiveness of this navigation framework.

the use of an Electrical narrow tilting car instead of a large gasoline car should dramatically decrease traffic congestion, pollution and parking problem. the aim of this paper is to give a unique presentation of the geometric modeling issue of a new narrow tilting car. the modeling is based on the modified Denavit Hartenberg geometric description, which is commonly used in robotics. Also, we describe the special Kinematic of the vehicle and give a method to analyze the tilting mechanism of it. Primarily experimental results on the validation of the geometrical model of a real tilting car are given.

this paper presents the determination of optimal reduction parameters for complex models of the Rational Krylov methods with using Evolutionary Algorithm. the presented algorithms facilitate a precise reduction of linear time invariant, multi-input and multi-output models. the elaborated algorithms are particularly significant for MIMO models, for which the individual channels differ significantly from each other. the prepared algorithms have been applied for the reduction of the subsystems models of a BP-1150 steam boiler.

this paper presents the design and real-time implementation of a Type-2 Fuzzy Logic Proportional-Integral Controller (T2FLPIC) to control the position of a DC servomotor, which controls a robotic arm. Numerous type-2 defuzzification methods were implemented and judged against each other. A comparative analysis withthe conventional Type-1 Fuzzy Logic Proportional-Integral Controller (T1FLPIC) and a PID controller demonstrates that the T2FLPIC has much improved performance than the T1FLPIC and the PID controller. this improvement is evident when it comes to handling of system disturbances and noise.

In this paper a comparative analysis is represented on various navigation guidance methods used for intercepting fast maneuvering moving objects. A glancing revision is introduced on relevant works within the introduction section. Four common methods for navigation under investigation. Results demonstrate their infirmity on smoothly intercepting a moving object. Hence, to improve the navigation guidance methods and to adapt them with robotic problems a modified version of AIPNG is proposed for 2D problems and is developed for 3D problems utilization.

An adaptive fuzzy logic control scheme is developed for tracking a square trajectory by the endpoint of a two-link rigid joint space robot. the control strategy is based on a direct adaptive control scheme in which the controller gains are adapted in real-time according to fuzzy logic systems such that the tracking errors between a reference model and the actual robot system outputs are brought to zero.
