چکیده

The complete strategy to derive theoretical predictions for pseudo-observables (PO) and observables (O) up to two-loop accuracy is based on the following steps: generation and manipulation of diagrams, renormalization, semi-numerical evaluation of diagrams. We perform the first step with the help of the code GraphShot (FORM 3.1) [ 1] while the last is performed using the code LoopBack (FORTRAN 95) [ 2] which makes extensive use of array handling, assignment overloading, vector/recursive functions.

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...

QuantiFERON-TB Gold and Tuberculin Skin Test for the Diagnosis of Latent Tuberculosis Infection in Children

Background: Appropriate diagnosis and treatment of latent tuberculosis infection (LTBI) play the most important role in the control of tuberculosis. This study aimed to determine the prevalence of LTBI among healthy tuberculosis unexposed children vaccinated with BCG using the tuberculin skin test (TST) and QuantiFERON TB Gold In-Tube (QFT-GIT) and comparing the agreement between the two tests....

Automatic Loop-shaping of Qft Controllers via Linear Programming

In this paper we focus on the following loop-shaping problem: Given a nominal plant and QFT bounds, synthesize a controller that achieves closed-loop stability, satisfies the QFT bounds and has minimum high-frequency gain. The usual approach to this problem involves loop shaping in the frequency domain by manipulating the poles and zeroes of the nominal loop transfer function. This process now ...

Coordination of a Bi-Level Closed-Loop Supply Chain considering Economic and Green Transportation Modes

In recent years, comprehensive researches have provided ample support for the supply chains in the coordinated decision-making framework. However, the issue of closed-loop supply chain coordination considering various transportation modes has not yet been addressed in the literature. In this paper, a two-echelon closed-loop supply chain consisting of a manufacturer and a retailer is investigate...
