Structure from Motion: A New Look from the Point of View of Invariant Theory

The Continuation of the Transatlantic Relations on the NATO Framework: A Theoretical Perspective

The unity of two Atlantic sides from the birth date up to now passed too many ups and downs and now on it remains as one of the satiable and long life unity. After the 11 SEP, there were many tensions and challenges among the two Atlantic sides which face the future of this unity into the doubts and suspicions. From this point of view the existing and expansion of the NATO could be mention as a...

Fuzzy sets form A meta-system-theoretic point of view

Probabilistic Sufficiency and Algorithmic Sufficiency from the point of view of Information Theory

‎Given the importance of Markov chains in information theory‎, ‎the definition of conditional probability for these random processes can also be defined in terms of mutual information‎. ‎In this paper‎, ‎the relationship between the concept of sufficiency and Markov chains from the perspective of information theory and the relationship between probabilistic sufficiency and algorithmic sufficien...

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...

Introduction to Schramm-Loewner evolution and its application to critical systems

In this short review we look at recent advances in Schramm-Loewner Evolution (SLE) theory and its application to critical phenomena. The application of SLE goes beyond critical systems to other time dependent, scale invariant phenomena such as turbulence, sand-piles and watersheds. Through the use of SLE, the evolution of conformally invariant paths on the complex plane can be followed; hence a...

اصلاح حرکت در تصویربرداری اسپکت میوکارد با استفاده از مدل‌سازی منحنی چند جمله ای

Background and purpose: Patient motion during myocardial perfusion SPECT can produce artifacts in reconstructed images which might affect clinical diagnosis. This paper attempts to present a new approach for the detection and correction of cardiac motion utilizing the data obtained during the imaging process. Materials and methods: Our method quantifies motion through polynomial curves modelin...
