In order to select the location of fire stations more scientifically and improve efficiency emergency management in chemical industry parks (CIPs), an improved risk calculation model for hazardous chemicals has been proposed by taking domino effect identification major installations into account. analysis effect, Monte Carlo simulation was used. Then, a established with optimization objectives ...

We propose explicit K-symplectic and symplectic-like methods for the charged particle system in a general strong magnetic field. The are also symmetric. can be expressed both canonical non-canonical Hamiltonian system. If three components of field integrated closed forms, we construct system; otherwise, constructed by extending original phase space obtaining augmented separable Hamiltonian, the...

the results of standard and augmented surgical treatment of partial accommodative esotropia have been compared in this study.in this sequential matched randomized double blind clinical trial, we studied 48 patients (96 eyes) with partial accommodative esotropia between the ages of 13 to to 144 months, referring to strabismus clinic of farabi eye hospital between 1999-2000. these patients were g...

Hazardous waste location-routing problems are of importance due to the potential risk for nearby residents and the environment. In this paper, an improved mathematical formulation is developed based upon a multi-objective mixed integer programming approach. The model aims at assisting decision makers in selecting locations for different facilities including treatment plants, recycling plants an...

Strong final state interaction (FSI) effects can play a central role in the Standard Model prediction of weak K → 2π matrix elements. Here, I discuss how FSI's affect the direct CP violation parameter ε ′ /ε by solving the Omnès problem for the necessary K → 2π amplitudes. The main results of this analysis have been reported in a previous paper 1 and are further discussed in Refs. 2,3. The resu...

Forward Automatic Differentiation (AD) is a technique for augmenting programs to both perform their original calculation and also compute its directional derivative. The essence of Forward AD is to attach a derivative value to each number, and propagate these through the computation. When derivatives are nested, the distinct derivative calculations, and their associated attached values, must be...

The integrated management of water supply and demand has been considered by many policymakers; due to its complexity the decision makers have faced challenges so far. In this study, we proposed an efficient framework for managing in line with economic environmental objectives basin. To design framework, a combination ANFIS multi-objective augmented ε-constraint programming models TOPSIS were us...
