Recently, a cryptographic construct, called fuzzy vault, has been proposed for cryptobiometric systems, and some implementations for fingerprint have been reported to protect the stored fingerprint template by hiding the fingerprint features. Also, solutions to the most challenging issue in applying the fuzzy vault to fingerprint have been proposed. One of the solutions exploits the idea of the...

In wheat, flag leaf, stem, chaff and awns contribute to grain filling through photosynthesis and/or re-mobilization. Environmental and genetic effects on the relative contribution of each organ were examined by analyzing the consequences of sink-source manipulations (shading and excision) and by comparing carbon isotope discrimination (Δ) values in dry matter (at maturity) and sap (two weeks af...

Fingerprint minutiae based biometric systems attract significant amount of attention as a secure user authentication method. In these systems, protecting the privacy of fingerprint templates plays a very important role in improving user’s acceptance upon providing their fingerprint information. However, due to the non-exact reproducible problem fingerprint minutiae templates can’t be protected ...

Cellular Automata are a powerful formal model for describing physical and computational processes. Qualitative analysis of Cellular Automata is in general a hard problem. In this paper we will investigate the applicability of modern SAT solvers to this problem. For this purpose we will define an encoding of reachability problems for Cellular Automata into SAT. The encoding is built in a modular...

We present a way to enjoy the power of SAT and SMT provers in Coq without compromising soundness. This requires these provers to return not only a yes/no answer, but also a proof witness that can be independently rechecked. We present such a checker, written and fully certified in Coq. It is conceived in a modular way, in order to tame the proofs’ complexity and to be extendable. It can current...

An end milling process is widely used in fabrication of complex contours and shape parts at high spindle speeds. Many researchers try to investigate one of important aspect, which come across during machining is the self exited chatter vibration which causes severe damage of the tool and quality of the machined surface. The present work is focused on the Magneto-Rheological Damping effect on st...

rapeseed cultivation in iran is growing rapidly while this product has been facing specific problems. every year a significant portion of edible oil is imported to the country from other countries. despite this deficit, a great amount of canola is being lost every year. therefore, in compliance with technical points, adding a suitable platform to the exisiting machineries may reduce the losses....

A Numerically-Controlled (NC) machine typically consists of a worktable and a spindle (or cutter) with several axes of freedom for positioning the tool. In this paper, we restrict our attention to machines having only translational freedom. We focus on 2D milling, which can only cut out planar objects, and 2 1 2D milling where only two of the axes are continuous-path controlled and the third ax...
