Nowadays, active safety has a significant place in the automotive field. Recent studies have shown that electronic driver assistance systems could be improved if the wheelground interface could be determined in real time from the driver’s requests. So, the aim of this paper is to present a real time estimation of the forces exerted between the wheel and the road, using neural networks. The orig...

This paper presents a novel Intelligent Inference System (IIS) for the determination of an optimum preshape for multifingered robot hand grasping, given object under a manipulation task. The IIS is formed as hybrid agent architecture, by the synthesis of object properties, manipulation task characteristics, grasp space partitioning, lowlevel kinematical analysis, evaluation of contact wrench pa...

The NNW-trending Dena Fault, with 140 km length, cuts the major structures of Zagros Fold-Thrust Belt in Borujen region. The fault has divided the region in two zones, in which different structural, andmorphological features as well assedimentation and seismtectonic characteristics have developed. This study presents a new interpretation for the kinematics of Dena Fault based on field evidence....

We study grasps of multiinger dexterous hands under the point contact model. Speciically, we are interested in high-quality force closure grasps. We abstract the problem into the space of force/torque wrenches where the quality is proportional to the magnitude of the largest wrench expressed as a non-negative combination of the grasp wrenches. This abstraction enables us to solve the problem by...

Despite prevention efforts, burn injuries among auto mechanics are described in the literature. Electrothermal ring burns from car batteries occur by short-circuiting through the ring when it touches the open terminal or metal housing. This article describes a 34-year-old male auto mechanic who was holding a wrench when his gold ring touched the positive terminal of a 12-volt car battery and th...

The mathematical approach presented allows main features of kinematics and force transfer in the loaded natural tibiofemoral joint (TFJ) or in loaded knee endoprostheses with asymmetric condyles to be deduced from the spatial curvature morphology of the articulating surfaces. The mathematical considerations provide the theoretical background for the development of total knee replacements (TKR) ...

S we introduced the Distal Jet* to the pro­ fession more than six years ago, it has achieved worldwide acceptance as an esthetic fixed appliance that can produce consistently reliable distal molar movement without the need for unusual patient compliance.1-22 Our experience with hundreds of Distal Jet cases has helped us identify key components of the appliance that could possibly be upgraded an...
