Protocol Verification Via Rigid/Flexible Resolution
نویسندگان
چکیده
We propose a decision procedure, i.e. an inference system for clauses containing rigid and flexible variables. Rigid variables are only allowed to have one instantiation, whereas flexible variables are allowed as many instantiations as desired. We assume a set of clauses containing only rigid variables together with a set of clauses containing only flexible variables. When the flexible clauses fall into a particular class, we propose an inference system based on ordered resolution that is sound and complete and for which the inference procedure will halt. An interest in this form of problem is for cryptographic protocol verification for a bounded number of protocol instances. Our class allows us to obtain a generic decidability result for a large class of cryptographic protocols that may use for instance CBC (Cipher Block Chaining) encryption and blind signature.

QFT Control of a Two-Link Rigid-Flexible Manipulator
This paper evaluates a new and simple controller design method based on QFT (quantitative feedback theory) for a two-link manipulator whose first link is rigid and the second is flexible. A piezoelectric patch is attached to the surface of the flexible link for vibration suppression of it. This system is modeled as a nonlinear multi-input multi-output (MIMO) control systems whose inputs are two...
متن کاملCONTROL OF FLEXIBLE JOINT ROBOT MANIPULATORS BY COMPENSATING FLEXIBILITY
A flexible-joint robot manipulator is a complex system because it is nonlinear, multivariable, highly coupled along with joint flexibility and uncertainty. To overcome flexibility, several methods have been proposed based on flexible model. This paper presents a novel method for controlling flexible-joint robot manipulators. A novel control law is presented by compensating flexibility to form a...

This research focuses on proposing an optimal trajectory planning and control method of two link rigid-flexible manipulators (TLRFM) for Dynamic Object Manipulation (DOM) missions. For the first time, achievement of DOM task using a rotating one flexible link robot was taken into account in [20]. The authors do not aim to contribute on either trajectory tracking or vibration control of the End-...

Background and aims Traffic noise barriers are the most important measure to control the environmental noise pollution. Diffraction from top edge of noise barriers is the most important path of indirect sound wave moves towards receiver.Therefore, most studies are focused on improvement of this kind. Methods T-shape profile barriers are one of the most successful barrier among many dif...
